Bitmain is proud to introduce our newest iteration of AntMiner, the S5+. This model is comprised of three hashing modules, each of which is approximately the same form factor as the S5, with the addition of an extra hashing board located in the middle. The new design squeezes 144 BM1384 chips into the same area that the S5 fit only 60 chips into.

Specifications:

• Hash Rate: 7722 GH/s ±5%
• Power Consumption: 3436W (at the wall, with AC/DC 93% efficiency, 25℃ ambient temp)
• Power Efficiency: 0.445W/GH (at the wall, with AC/DC 93% efficiency, 25℃ ambient temp)
• Rated Voltage: 12V
• Chip Process: 28nm
• Chip quantity per unit: 432x BM1384
• Dimensions: 275 mm x 372 mm x 155 mm
• Cooling: 6x 12038 fan
• Operating Conditions: 0 °C to 40 °C
• Network Connection: Ethernet

The three modules are linked together and operated with one controller board located on the middle unit. Customers must buy the set of three modules as one unit; Bitmain is not selling the individual modules of the S5+.

In addition to the higher hashrate, the AntMiner S5+ also achieves a better power efficiency than the standard S5. At 0.445J/GH, the S5+ is approximately 13% more efficient than its predecessor.

Comparison

	AntMiner S4+	AntMiner S5	AntMiner S5+
Chip	204x BM1382	60x BM1384	432x BM1384
Hashrate	2570GH/s	1155GH/s	7722GH/s
Power Draw	1500W	590W	3436W
Power Efficiency	0.58J/GH	0.51J/GH	0.445J/GH
Dimensions(mm)	432*442*133	298*137*155	275*372*155
Weight(boxed)	14.4kg	3.5kg	11kg

A New Cooling Solution:
The S5+ uses an unpainted aluminum casing. It also does away with the larger heatsinks of previous models; instead each chip is fitted with its own small heatsink for greater heat dissipation.

Each of the three modules contains two 12038 axial fans, one on each end. Each fan runs at approximately 4,200 RPM.

Ordered

2x S5+ with shipping to estonia
18.958 BTC

Ordered.

$2,475 shipped to US.

I went with bitmaintech's new hashnest offering instead

I got 10th for 6.66 btc.

Frankly I rather have this unit but the wife would kill me.



The price is good 2375 usd  for 7.7 th

with shipping  to usa 2473.37   keeps under that 2500 barrier.  (thank you)



As for my  choice of 10th for 6.66 btc

bitmaintech has sold 10,514  1th contracts for PACMIC v3 in the last 20 hours

that is about 7000 btc in sales.

It would be interesting to see what turns out to be the better buy.

This looks amazing

Nice to see it's a lot cheaper than the $3000 that was previously mentioned, updated spreadsheet

https://i.imgur.com/VC0ihQD.png

I think somebody inquired last time whether that takes into account the pending reward halving, and I believe you mentioned that you assumed a constant difficulty.  Could you clarify the parameters you're using just for this thread :)

considering trying this out myself, be interesting to see how it plays out

The 10x v3 should make around 0.105BTC?

I would guess the v3's unless your power cost is very low.

Couldn't resist at this price.  It's been too long since I got a new miner. 

Plus winter is coming; this 1 miner will heat 1/3 of my house.  Hopefully it is not too loud in the basement.

Sorry, yes assumes static BTC/USD and difficulty, no-one knows on the former or the latter just gives a quick baseline to work from according to your own thinking and risk

EDIT: The reward drop isn't for nearly a year so didn't see the point including that, some people will have import duty on top and maybe PSU's as well.

Also assumes no halving?  Since that one is semi-reasonably known (absolutely in block count, more fuzzy in date)

i hope someday my solo mining rig got a block, so i cant buy this miner  :D
this miner price is more than 30.000.000 in indonesian rupiah
with ship, tax and custom duties, it could be more than 40.000.000

my calculation, 3436watt is 120.000 idr in 24h
i assume that static diff, coins per day 0.07368986 = 273.000 idr, so the income is 153.000 per day
and 261,4379085 days to get roi  :D

Please update regarding my question - Question from BITMAIN

I am really wonder, Does all China states and cities charge apply so much tax as 1.527 BTC (403.750 USD) by buying each single unit of s5+ ? what about hongking shipping does any such tax applies on hongkong shipping address ?

phil, I cannot really get that pacmic stuff.
You pay for Th, then they will pay you until principal is paid, then they say the machine belong to them.
So, where is your profit?
Is today the first day and is there a pacmic thread?
Thanks

So we need to buy 3x PSUs to power this thing?

Yeah you will need 3x PSU for this to run.

Or just two of these https://www.protact.net/netzteile/6/servernetzteil-mit-2.250-watt-und-12-pci-express-stromanschluessen?c=8 (https://www.protact.net/netzteile/6/servernetzteil-mit-2.250-watt-und-12-pci-express-stromanschluessen?c=8) (I am guessing).

I don't think you can use only 2x PSUs. According to bitmain's product info

I don't see why not.
As I understand, there are 9 boards, just go 5/4.

pacmic: it looks like it gives you 69120 satoshis/day in bonus per Th (0.185/day or $5.5/mo). So, 10Th=$55/mo bonus, which comes down to ~1.8% interest.
They don't include the cost of mining, so it looks like contract will be paid off in ~73 days if difficulty increase is 1.57% on average.
So, you'll get ~$13 of BTC in bonuses per 10 TH (6.66 BTC), so investing ~6.7 BTC will get you 0.048 BTC in profit in ~73 days
The risk is that difficulty might increase faster and you never get your 6.66 BTC back completely

  link

https://www.hashnest.com/contracts


they pay two payments one is interest (your profit) one is contract payback.

it comes to about 12-14% per year.  so 1 or 1.1 percent a month.  my 6.66 btc should earn .21 btc profit in about 75 days.  so in theory 6.66 btc will be 6.87 btc

I am getting 0.00006912 BTC/day (6912 satoshis) for one contract (1Th), which is equal to ~0.0021 BTC/mo per contract.
Hence, 10 contracts (10Th) will get someone 0.021 BTC/mo in "interest" on 6.66 btc spent.
Total expected interest on 6.66 BTC invested in 75 days (until the contracts are finished)=~0.051 BTC
As a result, i am getting a different interest rate than you.
What is wrong with my math?

I'm tempted to buy one of these S5+ miners, but my lack of faith in Bitmain firmware is preventing me from doing so. I think I'll wait for the first batch to arrive with guinea pigs customers & see what the feedback is before making up my mind. Hopefully they have finally managed to find someone who knows how to write their firmware properly using the mainline cgminer instead of their terrible fork using crazy settings.

Fair enough as to waiting on the guinea pigs to report back on how these monsters behave in the wild ... though I'd take the notion that bitmain write terrible firmware for their rigs with a pinch of salt (last I checked the so called best ever cgminer never neither increased my earnings nor reduced my electric costs over the bitmain fork ... ever!). I'm just frustrated there is no alternative mining software for their rigs readily available .... and the noise from this beast of-course.

..... and the heat!

Don't forget it's a 3000W heater in disguise as a Bitcoin miner.  ;)

I can deal with the heat about oct 15th or so. not now. So I think I will pass.

I will send you a pm

AntMiner S5+ Batch 1

SOLD OUT

 If you have 2 PS with enough +12VDC power output, use one to power 5 blades the other to power 4 blades + controller + the FANS (per the published specs it looks like Bitmain might have gone to higher-airflow Delta 4200RPM fans on the S5+ vs. the 4000 RPM fan on the S5, so probably 14-16 Amps JUST for the fans, possibly as high as 20A.)




 This is VERY unfortunate, there are folks that would be interested in a "same form factor as the S5" 1/3d version of this.



 Limitations of the hardware mostly, possibly a DRIVER update might help a hair but there isn't much you CAN do to "optimise" an ASIC-based unit once it's in production without a complete redesign of the hardware itself.

That was either fast or a great marketing strategy.

Or they only had 20 in stock.

I think i saw they had 200 ready to go in another thread..

Where does the better efficency (+13%) comes from? Is it clocked @ 325MHz?? Any changes in the Vcore?

1155 (GH/s) / 60 (1384 chips@S5) / 350MHz (frequency@stock S5) * 432 (1384 chips@S5+) * (325 MHz S5+ or X) = 7722 GH/s

Looks nice...

greets

Interesting!

6 X 4200 RPM fans means this thing is going to be insanely loud - even compared to the S5.  

I'd love to see if you could under-volt this, to allow it to run on 2 X 15A breakers.  Otherwise maybe Bitmain can offer a scaled-down version (6 hashing boards) running about 5.15 TH/S at about 2300W?

about to order one of these beauties

edit : just noticed they are sold out of batch 1

I see 8.9BTC not 6.6BTC. 

Looks like they still have some in stock.

I think there are so many people going through new miner withdrawals they sold many of these as soon as they were available today. They may have also had a large scale operation cut a great deal with them.

Total BTC Transaction is 9.3004BTC sent for 7.7 TH.
I have a slew of S3s to move and decided to take a gamble.

I will say I do not like several things about the design. I think someone else pointed out the huge potential for a single controller card to take down the rig.
Taming the heat until it cools down will be a PITA.
I feel like many regarding noise, it is a part of mining, but I understand some people are unable to deal with it, or their wife is unable to deal. Fortunately I love the sounds of high speed fans and my gf doesn't live with me so I do what the hell I want.

I have also had my issues with Bitmain and am being a hypocrite because I said I wouldn't ever purchase a new miner from them again. OTOH I've had great success with the used S5s I picked up and the past couple of months I have seen great returns on the repaired S4s, S5s, and S3 / S3+ units.

 My efficiency is the only thing holding me back at this point along with needing another 100 amps of power dropped in my main, but I am discussing this with the power company and local laws requiring a licensed electrician to do the work. If the power company came out and dropped another 100 amps of service for me they will not turn it on until a licensed electrician is here to perform the work on my end. I work with someone who was reported when he had the service increased to his shop for a rebuilt plasma machine we worked on for a month - and I helped him with the work. He is competent to do the work, but they want that license. If his house burnt down and he didn't end up with a licensed electrician involved there is no homeowner coverage.
There is a huge 'good ole boy' network around here and the electricians, etc will get their money.

Will I make up 9 BTC in efficiency? No.
I will sell the S3's for 80-100 each or so. I have people I work with who will pay me to come to their house, set it up, and show them how everything works. Not to  mention I can sell them an ATX PSU because I have a dozen not being used.
I also have some fantastic break out boards from sidehack and novac to go on a DPS2000BB power supply so people can connect 3 or 4 S3s. I bought many S3s and S3+ units and sold several S3 "packages" which paid for my 2880 PSU and break out board along with several other parts of my infrastructure as I've evolved this year.

There are many people out there who grew up geek like many of us. They want to mine coin for the same reasons as many of us - because it is a challenge, fun, will change the world, and on. They aren't afraid to pay someone for their time and energy, not to mention support. It is nice to come home and see a 1/2 gallon of crown sitting by the door with a bow on it and a note that says something like "thanks for all the help!". I haven't sold anything online dealing with BTC.

I do like the fact the S5+ is based on a proven chip.
I do not think the S7 will be shipping to US customers until mid-October. I hope I am wrong, I really do.
I also wanted to open the door with Bitmain again. I've spoken with them privately a few times and believe they have been sincere in trying to patch up our relationship. I had a deal over the S4 power supplies go very badly, and have dealt with the same issues as everyone with firmware, etc, but they have support people who care, and that speaks volumes to me.

I am slightly concerned about the efficiency of next-gen miners popping out at .3 by the end of September, but when I saw Sfards isn't getting product on shelves for reasonable numbers and were originally supposed to have miners in our hands two months or more back, KNC isn't letting anyone have anything, unless you want a lightbulb you cannot really get much from anyone outside of great stick miners from Sidehack and Novac. Spondoolies haven't even given us a peep that they will sell to us, much less have something working they will let a group-buy be involved in. I feel like time is more important than ever with the halving a year away. I know what I think will happen, and it looks even more gloomy for most of us small guys then.

We have the price kicked under 2500 so no major attention there I hope, but I am not going to stress about this. If it ends up in a two week customs evaluation so be it. The way it goes is the way it goes today for me and mining, but I feel like it was a good decision to get my nano farm updated, some additional hash at a decent rate, keep myself out of cloud mining.

I hope this is a killer toy to play with, and outside of a couple of SP20s, S4s, breakout boards and some cables everything I have is used. If I look at the used market right now the prices are way out of line. I couldn't find anything used I would even consider relative to the price of this unit. The initial prices were way out of line for the S5+, and I hope the activity they have seen with the price under $2,500 has shown them something positive.

I know many people think it is a bad choice, but consider it may be a good choice for many people. As long as Bitmain sends me what they say, It makes sense for me.

you are mistaking my post on bitmaintech's hashnet division.

 they are offering 10th for 6.66btc

they opened the cloud contract and the beast miner on the same day.


I purchased the cloud contract as the beast will not work for me until winter power rates start in OCT

­> There are 3 PCI-e connectors for +12V DC input on each hash board and ALL of the 3 are required.

This means I cannot power the whole thing with 3 EVGA 1300W. Because they have only 8 PCIE (4 single and 2 split).

Edit: I can buy a split PCIE cable to replace 1 single PCIE cable per PSU. Each board will be powered with a single connector and 2 connectors from a split cable.

shoot me a pm I think I have some spare 2 plug evga cables.

each evga psu will supply 1200 watts 24/7/365

so 3 should give 3600 watts

I prefer to use more power supplies in those situations. Obviously that depends on it being an option for you. IMO even if it is a smaller one so you are not as close to maxing your others. If you aren't calculating the draws correctly relative to the Y and using good Ys, you could get yourself in trouble. It can make a huge difference in the safety factor.

I plan to use two 2880s for one S5+. I may have another small miner or something which draws a little wattage also connecyed, but certainly try to stay under 75%.

B1 sold out!

Edit: Not anymore it seems :)

 The latter - they are using 16 chips per chain = .75v per chip instead of 15 in the S5 = .8v per chip.

 I WISH since they decided they were going to do something like this that they had gone to at least 18 and optimally 20 chips per chain, for some SERIOUS efficiency gain.



 Spondoolies got bought out or merged a bit back, no clue if the resulting company has any plans to ever sell to anyone else ever again. Their web site hasn't been updated in quite a while other than the "news" of the buyout/merger event.


 A pair of 117v 15A breakers is good for over 3500 watts at nominal voltage.
 2 server power supplies should work that way at stock clock, though with VERY little margin, and I would NOT try that if your outlets routinely deliver much less than 117 VAC.
 Probably NOT a good idea overall.
 I'd also be very cautious about even trying this unless you have checked your wiring and it's in VERY good shape - or unless the wiring is oversized (I always wire my 15A circuits with AWG 12, which is specced for 20 amps capasity, so I never have to worry about the wiring overheating - the cost difference from 14 AWG as specced for 15A is minimal).

After originally being put off by the S5+, I'm now warning to the idea. If I retire my existing hardware, I have enough amperage to put this in our cage at a data center with enough headroom to be comfortable. We're running at 208 volts.

The trick is the power supplies. Basically you need something like 1300 watts each? I don't have anything like that right now.

And this is a string design, so there's no under clocking options, right? You have to feed these beasts the documented power and that's it?

Bitmain recommends their own server power supplies, of course.

Too bad this guy only has 1100 watt PSUs left. He's out of 1300 watt units, I think:

https://bitcointalk.org/index.php?topic=1037372.0

There's this 2880W option too. I guess you'd need two of them, which is cheaper than the Bitmain route where you'd need 3 1600W units:

https://bitcointalk.org/index.php?topic=966135.new#new

Any other PSU options that would provide enough power but be reliable and affordable?

Yes, they merged with a company and Guy said they were going to do industrial size things for themselves and there were many questions ignored along the lines of - if the home miners would even be able to put one of the "industrial" miners in a home, or, if maybe it would be possible to form a group buy and host something somewhere, all depending on exactly what "industrial" means in that context. Maybe I should have clarified a bit further. I expected to hear something by now of what they are doing if they have something of next-gen status going out the door, or even close to going out because even if us nano guys couldn't afford it a B2B or self-mine rig of high quality is still big news.
In the official Spondoolies thread it isn't that far back where Guy was talking through exactly who they merged with and what the plans are / were.



Yes, the S7 sale date is very much int he air, but as others have said it is probably being installed or has already begun being installed in the "test-mines". I believe It comes down to a decision of when relative to competition. If there is not any serious competition to S5+ efficiency, ie Sfards doesn't get  it together or one of the other players who can actually get something on shelves a single manufacturer can wait, mine, play with pricing structures, and generally take all the time they want. My end of September guesses are because many miners will be ready for heaters by then. If someone drops a product to fit that segment I think the pressure on Bitmain to bring something else to market will increase proportionally.

From a home miners point of view I agree with the efficiency of 20 chips / chain. However from Farm point of view they do not need that efficiency because of their low $ /KWH. If the S5+ had been built with 20 chips / chain it would have cost more and have a lower hash rate.

In fact on my maths even an S5 which is slightly less efficient than an S5+ so long as your electricity is < 13 Cents /KWH then you do not, on the current difficulty, want to underclock, less than this and you should overclock.

What we can hope is that they have made the S5+ such that it can accept an undervolted supply which in combination with reduced frequency will enable us to improve efficiency as the difficulty increases.

Rich

Can this be rack mounted?  Does anyone know?  Looks like brackets on the front sides but they seem funky

Appears to have some stock again.  Thank you Bitmain for not making it just China market.   

Now I need to do some ROI math.  Wish it had PSU's included with it, but not a deal breaker.

I can personally vouch for Finsky who is the US distributor for Jabberwock's break out boards.
I purchased some of the first one's he had sent form Jabber. I think they were the first ones and they are still running hard right at this moment. I'd managed to find my own supply for the actual power supplies and was only getting the boards, but my last order included power supplies as well because prices went up all over for these babies.
Finsky and Jabber are both great guys and great contributors to the Bitcoin scene. I can't say enough good things about Finsky though as he is the one I dealt with the most. We actually ended up talking about all sorts of things over days or weeks. He can also hook you up with cables because keep in mind you'll need both ends of the cable to be the same. They must be the same end which you connect to any of the Bitmain S3, S5, etc series miners. In other words the sockets go on both ends of the cables because the boards have the pins just like the miners.
I'm assuming the S5+ has the same connection style, I have cables of all varieties so haven't paid close attention to that part heh.

I also purchased many 2000 watt power supplies, cables, and breakout boards from Sidehack and Novak:
http://www.gekkoscience.com/products/IBM2K_board.html
I think this board is a work of art. It has many functions which would come in handy with a miner setup this way and I am considering using these. The DSP2000BB Power Supplies are inexpensive and you get pure quality with the boards.
The functionality for the DSP2000 breakout board is shown on the smaller power supply document:
http://www.gekkoscience.com/misc/V0.5_Board_Doc.pdf

You cannot go wrong with either one of these rigs. It is truly a matter of looking at the details and determining which fits exactly the way you want to set things up.

Consider some of these data points:
The 2880 has a fan module which connects to the front. You will receive that with the power supplies if you order them from Finsky, but with the 2000 you can install whatever fans you want and control the speed. The 2880s are howlers, but if you stack two 2000s, put two 120mm fans on them and run them hard you are going to make noise with them as well. If noise bothers you.

Where are you located? The 2880 break out board is made in Europe so I imagine shipping is less for them. Finsky handles the US and then again Sidehack is in the US.

If you want to do current sensing, load balancing, fan control then you'll want sidehacks board.

The DSP2000 is gold rated where the 2880 is platinum. Not a huge difference on the monthly power bill for two power supplies, but it certainly adds up over time, and with a larger quantity.

There are other things you may find which are a priority for you, but fortunately both of those guys are very helpful and most importantly honest. They will tell you if you pick something which doesn't make sense even if it costs them a sale. You cannot buy that kind of honesty, it is there or it isn't.

Strange, I am trying to place an order for upto 10 s5+ but it's stating it's out of stock :(((

Shows out of stock again.  It might have had some saved in carts and released them causing a small second time of showing stock.

But now I'm just getting out of stock.

Please folks -- ears on rack mount chassis are NOT the only thing you use to mount them! Or better not be.
All heavy rack mount gear is supposed to be sitting on a support shelf/brackets. The ears are mainly only to keep them in position.

https://i.imgur.com/VC0ihQD.png

For me there's ROI in about 180 Days as my Electricity rate is about 0.08    ;D

BITMAIN please offer the option to split this into 1/3 miner with these specs: 2.6TH@1150 watts for about 800 USD.

Is very easily doable with the design of this since its essentially 3 miners stuck together.

Wow! Thanks for the great info. Very helpful.

I'm in the US. If I go through with this then the S5+ would be in a data center, so fan noise isn't a problem. The louder the better ;)

Since noise isn't a problem and I don't need anything fancy like load balancing, it's looking like a pair of 2880 watt units might be the way to go. But I'll also take a look at what gekkoscience has. I'm already fan of theirs (ordered my sidehack sticks minutes after they went on the market).

this spec is for upcoming S7? probably...

Anyone know if the S5+ is strong enough to be placed on rail style shelves? Or does it need to be on a full shelf (i.e. supported across the middle)?

It's hard to tell from the picture how physically strong across the middle this unit is. Is it really just 3 units bolted together, or are they integrated in a single piece of sheet metal?

Now that I look at the dimensions though, I'm not sure it's wide enough for some rails. Looks like it's only 14.6" wide.

What is the monthly growth of difficulty? Zero? If yes  then calculations are not useful.

2 is fine, still only about 165W per PCI-E.

When is batch 2 planned?

Looks like batch 1 already has been sold out for sure, has not shown up with available again.

Crap, looks like I missed out on batch 1.

So how many https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 does it take?  Also how many PCI-e cords does each one have?

It seems like it would be 3 of those.  But I could not tell if they had 6 or 8 PCI-e cords from pictures.

12x PCI-E

Thanks! Could not find this.   To bad they did not make it only use 2 of these PSU's it's close on watt's.   

But I guess PSU's were not big decider on when they made this unit.

So each of the 9 hash boards draws about 330 watts apiece?

So the remaining 500-sh watts is for the fans and the controller?

Exactly!  I don't see any benefit in helping give Bitmain an advance on their operating costs.  I enjoy mining as much as anyone.
But only if after the principal is paid you walk away with used S5's or some collateral, other than that it's a loan. 

Itll be about 90W for the fans, 20W for the controller and the rest is PSU inefficiency. I calculated with 90% PSU efficiency so at 93 it makes it 170W per PCI-E when using 2 a board.

I'm a noob here so feel free to correct anything I say.  Also forgive the grammar mistakes and spelling, just off surgery and painkillers and typing don't go together.

Question 1:  Does anyone know the size of Batch 1 production run?  (In other words how fast is the network going to explode with centralization and difficulty through the roof)  
Question 2:  Does anyone know when the Batch 2 Production run will be available and its size?  (Are they doing reserves? in small stock (IE I don't buy 100 of em))

Comments and analysis on the Hashnest offer.  I looked at the contract (and going over legal contracts is part of what I do for a living).

I'm agreeing with most other people on the Hashnest deal.  That's basically a loan so you can finance their capital costs on revamping/retooling their own data centers (probably with beefy miners we haven't even seen yet), and perhaps production operations.  While doing that you get a small 'bonus' (in the financial world we call that interest) in the meantime until that principal is paid back.  And the 'bonus' is variable rate they are paying YOU for that loan is a lot lower then what a bank would give them (variable interest/bonus rates they are letting a volatile market decide).  And they have the ability to STOP paying you if bitcoin takes a crap, their costs skyrocket, or some other disaster happens.  Which is a big no no.  

Go to a bank and try taking a short term business loan out.  Tell the bank you want the clause put in that if your business model becomes unprofitable and you haven't paid them back after 120 days that you stop paying them back and they do not get any accrued interest or principal payments during that time period.  But should your model recover, you will start payments again.  Oh and that YOU not the bank gets to decide when that period starts and stops, and that it can start and stop at multiple times.  And the stopping can include the time period of forever.  IE  Never paid back with no collateral.  See how fast you get laughed out of the building, if not escorted out by security.  Hench why they are trying the cloud mining contract deal.  Sucker born every minute as they say.

Second thing, or are we at three at this point (Hell I don't know):

I also did a quick comparison between their second hand S5's they are selling (of which I just purchased two literally a day ago).  And the new S5+  All these things are from the bitmain post or their own website.


First Warranty:

Second hand unit, (don't know what they it through)  Only get 30 days. | S5+  New unit, 90 days.  However these are Solid State devices.  If taken proper care of they should technically last forever.  (We all know that's not true but you get the point.)

Hash Rates:

S5:    1155 GH/s      70.4 or so dB fan (AKA Loud as F)
S5+   7722 GH/s   6x70.4 or so dB fan (AKA Data Center Unit, Loud as F x 6  Never gonna be a home miner unless you got a sound proof basement)  

Only good thing is the cooling system of individual sinks seems much more efficient on the S5+.  That's also probably partly why the operating conditions increased from 35C to 40C as a maximum over the S5 as well.  It also means the product can likely stand up to a lot more wear and tear before components start giving out due to heating and cooling.  IE they just improved their manufacturing processes.


Price to GH/s:

Second hand:  $351 (when I got it, now 348 today, but I'll work these off my price.)
S5+:              $2375  On their website

Now remember this is basically 6.5 S5 miners or so strapped together, units with three boards each.  So lets to a Gh/S to $ comparison.  Also I'm looking at a brand spanking new unit vs a second hand, but both do have at least some warranty coverage and can be tested and nailed out of the box.
$351 gets me 1155 GH/s
$2,375 gets me 7722 GH/s

$351 goes into $2,375 = 6.766x  (I know you cannot buy a .766 of a miner but humor me)

So I could buy 6.766 S5's for the price of an S5+  Simple math 1155 Gh/s x 6.766 = 7815.17 Gh/s  Then let us do the math of that between the two:  7815 Gh/s / 7722 Gh/s  = 1.012  

[b]IE  You're actually getting 1.2% better return on Gh/s for $$$$ spent with the simple S5 over the S5+.[/b]


Power efficiency comparison:
(I'm not doing power consumption comparisons because where I'm at that's irrelevant.  Maybe where other people are that is important.  Efficiency is the key for me.)

Now here is the bright spot where the S5+ seems to really shine though and where all those engineering dollars went.

S5:     unit is 0.51W/GH
S5+:   unit is 0.445W/GH

Math:  .445W/GH / .51W/GH = 0.8725

This means you're using almost almost a full 13% less power from an S5+ than running multiple S5's.  12.75% less power to be exact. :P  That would be a significant impact on your electrical bill if you're in a high kW/h area.  Then again, if you're looking for a fat tax write off because you're smash and grab bitcoin seller paying ordinary US tax rates (which will be most home people) and you're working this as a cottage business in your basement, that's a business write off you're going to lose.  

PS:  Regardless I'd take the lower operating costs, but this is definitely for people who have committed space for serious mining operations.

Overall Summary:  GH/s ain't that great for the price, but the 12.75% discount on the power usage isn't too shabby.  Someone mentioned breaking these up into multiple units.  I'd have to see the specs and re-run the analysis over on that single unit to see i that was worth it.  Especially at the price of $800 per single unit they quoted, which is a slight premium over the 3 stacked units.

Cniht   :-\

Do you think it's going to work at 90% efficiency with their own PSU power supply APW3-12-1600-B2 https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 (https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694)  (Note they claim 93.8% efficiency)

Or is that thing just a POS under normal working conditions and we should stick to normal computer PSUs?

I'm guessing you are wanting to hid from 1 activity.  But when looking at watts this high going from ATX to server psu's can save you a lot.

Someone can go out there and compare.  But unless there is a big deal/bargain on a good ATX server PSU's win on price anymore.

Its pretty accurate, single voltage PSUs tend to be very efficient and the power measurements are taken from the wall.

The product page specifies the controller board must be powered on after the hash boards.

I will use a seperate smaller gold or platinum atx unit, or put a time delay relay inline with the second 2880.
The relay wouldn't void warranty would it? It is still being powered on after the hash boards.

I can't answer that, sorry. Worst case you're frying and paying for a controller, can't be that expensive.

I'm not worried about frying my controller from simply adding a relay. That kind of thing is something I tell people how to do over the phone a couple of times a week. I'm more concerned about posting pictures of how to do so and then having my warranty voided, that is if I went that route. I won't do so for the sake of warranty until I know something in writing from BITMAIN.

I should have been more clear in my reply because I mainly wanted to point out to anyone who hasn't noticed the product specification page states you have to power the control board after the hash boards are started and most people are going to need a separate power supply for doing such until they are shown an easy way to do it. Many people aren't going to know how to do this, that, or the other which accomplishes the same thing. That is obvious from how many people purchase on / off switches for the mobo on / off for their ATX power supply. Not that some don't do it for other reasons, but I am talking in general a lot of people purchase that particular part thinking they need it, or it is a requirement. Remember the thread about the 20 dollar "special" paperclips?

I will shoot a ticket over to support and ask the same question about the relay to test the waters.

Not sure what you mean by that part in bold part.

Can't believe the day finally came to a new Miner being released? Any reviews or videos on this product out yet?

I do see that power ratio vs. hash rates is a win vs the S5, but here it stops in my calculation of reaching ROI in 180 Days or more.
Everybody seems to forget the PSU needs for this evel miner.
If you need 2 x 2880 Watt breakout boards around 340$ and 42 PCI cables for around 126$ and then last 2 x IBM Blader sever PSU of around 90-100$ for a refurb. So total you have to add around 660$ pr unit to just get this beast up running!
Thats a hughe cut in earnings....
If you use the same amount of Breakout boards, cables and Blade psu`s for an S5 setup, you are able to run 8 S5´s for the same amount of money, giving 9.6TH.
If someone can explain to me why this should be a better deal, please explain, since I cant see it :-o

Hi all .. I am new here. 

Can someone, with the right knowledge, help me with the points below, please.

- Where is the manual?

- Is the extra wattage from the 3 PSUs beneficial for performance efficiency?

- Is there any instructions on how to start the hash boards before the controller board?

Just a PS to everyone.  

I could be just extremely high on narcotics (I am on some good stuff after surgery) but I think they are selling the S5+'s again.  As of the time of this post, 7:15 AM EDT.  Maybe they are just doing it a few a day at a time to test demand.  Dogie I think had the ability of little birdies to whisper in his ear I think.  Maybe he can find out what the marketing scheme is for distribution on these babies.

Wish I had a Server PSU that did 1600W in a normal  US 110-120V outlet.  Anyone know of one which is also rated in plat or titanium 80+ let me know connections included of course and miner ready.

https://www.bitmaintech.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B (https://www.bitmaintech.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B)

I think they mention this in the first post at least.  I'm assuming by their specs they are using their own little PSU device since they also recommend it.  It gives efficiency and temp it was taken at.

Specifications:

1. Hash Rate: 7722 GH/s ±5%

2. Power Consumption: 3436W (at the wall, with AC/DC 93% efficiency, 25C ambient temp)

3. Power Efficiency: 0.445W/GH (at the wall, with AC/DC 93% efficiency, 25C ambient temp)

Their PSU:  https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 (https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694)
(unfortunately rated for a 205V and at for the foreseeable future I am someplace that cannot take neither the noise nor the electrician dropping in the appropriate plug, so it's out for me but I can dream baby.)

I ordered shipped to US  ;D

There isn't a manual or firmware online yet. Normally the manual on a + model is very similar to the base one.
They will get one up there though in the same place the others are:
https://www.bitmaintech.com/support.htm

It isn't that you must use 3 PSUs if you can accomplish the same things those 3 would do in a way that doesn't violate the warranty.
They require each hash board to be powered by the same PSU.
You can use a separate PSU for a separate or more hash boards.
They require the controller board to be powered by a separate PSU so it comes on after the hash boards are already powered on.

A bit of advice I learned. Don't void the warranty. It simply isn't worth it.
Always buy direct from BITMAIN if it is a BITMAIN product. Unless you get something in writing from BITMAIN stating otherwise when it comes to warranty, there are not any official resellers. If you do not buy direct, you aren't covered. This includes zoomhash. Again though, I have seen special arrangements made, you'd better make sure you get it in writing from BITMAIN not the reseller. I've been both screwed and saved by BITMAIN on this. Once I bought from Zoomhash and it was a fiasco, and once I asked BITMAIN first and they told me the vendor (not zoomhash) was not telling me the truth so that saved me a chunk of change.

Unless you are a rich guy who can afford to drop thousands over and over and don't care if 7.7TH are down, don't and do brother.

yes , Here are some Videos presented by ITOP Corp (http://www.itop-corp.com)

http://www.itop-corp.com/asset/file/image/20150814/20150814103047_22202.jpg (https://youtu.be/jGK2ZGuFZWI)

I guess with the extra wattage the PSUs will run with slightly less heat.

What do you mean by "and don't care if 7.7TH are down".. Do you mean down (failure) due to not following the warranty instructions?

@cniht & @sloopy,
I appreciate your responses.

Looks like you're powering that with 5 x 750 watt PSUs? Hard to tell which PSUs are powering what, but I'm thinking of a similar set up.

Are you seeing around 3500 watts at the wall, as advertised?

With those cables coming out the top plus the power supplies, this will take a lot of space out of a traditional rack.

i can't wait for someone to make a good review on this rig. how loud this machine is? they fail to speak about that but i'm not willing to bring a helicopter in my home as a miner.

And still no one who can tell how this unit should be a better deal? I think its more expensive to own and run than regular S5?

5x750watt server PSU , I don't think it is enough , total 750*5= 3750 *85% (power supply efficiency)= around 3187.5

if you use server PSU , should be more than 3500 , depends on the powersupply efficiency .

okay  lets do it this way.  I have 3 psu's on hand to run it.    this is 2473 shipped to my home.

6 s-5's are 2267 shipped to my home

6 s-5's with a little over clock do 1250 each = 7500gh  at .5  =  3750 watts    6 controllers  so you can disable 3 of them and run   30 watts less so you have 3720 watts


1 s-5+ with a little under clock will do 7500gh at .445 = 3337.5 watts   so   you get equal hash  and 400 watts difference in power.

that is about 30 dollars a month in power  in favor of the s-5++  

 price is the same for psu's

price is 196 more for s-5++   and at 1 dollar a day power savings the price is  =  after 196 days.

so until the 196th day the s-5's ae cheaper.  and even at day 196  since you double up on the s-5 controllers you have 3 spare controllers.


Or let the s-5's each use 1 controller power cost is 32 a month. so in 180 days you are equal cost.

The risk of the s-5+  is the controller dies you are dead in the water.
The 6 s-5's allow up to 3 controller deaths and you can just double up the gear.

Most guys buying an s-5+  are really big and getting a bulk deal.

http://itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)

We tested running with one 2880 and 3x750 server PSU , it is 92DB , just for your reference .

Thanks for the clear answer, that just tells me that I should stay away from the S5+ if I cant reach ROI in 180 days.

Just bourght 50 used S5 instead to up the farm, so it has to be really big farms if they see any ideas in buying this unit. Home miners seems to forget the 600$ + they have to add to the cost just to get this beast running.
Heads up for your clearing I thourght I was missing something...

Yes, that is what I meant, and do not take my posts or replies as harsh in any way, but I do hope to present things as they were presented to me by BITMAIN representatives via e-mails.

The phone support people I have dealt with have all been over the phone. Those guys answer the phone from the main number and transfer to customer service. I do not know if they are all living in Colorado, but all spoke english very well, and were straight up with me about the way things are. - Unfortunately they do not make final decisions. At least decisions like should we swap this unit for another, but they can certainly help you out, and have me. I went through batches 1 and 2 of the S4 power supplies before I gave up, but it wasn't from those particular support guys lack of trying. Through many discussions with several of them I learned what happened, what was going down, what they could do about it, and what they couldn't. I have mixed emotions about them offering to send me a server PSU (DSP2000) with a break out board, but today I look back and think at least they offered when they knew they couldn't fix theirs.

Email is where you talk to people who have the authority to make decisions. I spent days reading existing threads for the products I was interested in either before or after I purchased them. I wish I'd read every page before, but some of the units were used deals I grabbed quickly from e-bay. My worst experience was a new purchase through Amazon. Avoid those in my opinion although you can find a deal on ebay sometimes but you have to watch and be patient. The prices are generally much higher than they are here in the marketplace.

I also avoid resellers for new equipment because they simply have to mark it up. I will again throw an exception out there. Lee from Lees group seems solid, but Phil and others can give you the best information on his setup. He is more local to the factory, gets great deals, and I have seen him meet and beat BITMAINS store price, but he requires you host with him for X amount of time which I cannot do. When it comes to the point I cannot afford to mine I will have to pickup another addiction of putting my hands on something. I have no doubt others can vouch for other resellers who they have seen with great deals, but the only ones who matter are the ones you can get that deal from today, and (repeating myself again) who BITMAIN will put in an e-mail they will warranty for that person / company.

If you are asking everything specifically looking at the S5+ I have to say, my expectations of the S4 were too high relative to what I received. The product, was not what I expected for the money I spent, so the S5+ I am keeping my expectations in check. Even though it was 9+BTC /  2,500.00 USD I know it very well could arrive DOA, maybe one or more boards do not function, maybe I have to fight it a bit to get it on the net, maybe the CGminer is old, maybe the corner of the shipping box is ripped off, maybe there are fork truck holes through the box, bent heat sinks, loose cables, dirt and rust, and on, and on. I am not saying these things would all be the fault of BITMAIN, I am saying these are more realistic expectations from what I have seen reported and through my own experiences. I do expect it to be packed well, even though there is a thread right now for one of the used S5 batch 7 units where the guy said his wasn't. It has been rare I hear of them using poor materials or methods in packaging. All of my S4s were packed perfectly in anti-static and a great soft foam cage to handle bounces. I expect good fans. They will be loud as hell and rock the house, but again the S4 had some issues with fans and needed to have the stickers pulled back and grease added. BITMAIN took care of people on the fans. I think most of us who lost a fan under warranty bought our own replacements and sent the originals back, but I know of cases where BITMAIN did send a fan out without having the original back as well.   
Other than political stuff with warranty and the time it takes to ship things they have improved, and there are always opposing views to anything you say here, but consider this. I was one of the biggest opponents to BITMAIN gear when the S5 was released and you couldn't have melted one and poured it in my house without getting shot, but a few months ago I picked up a couple of used ones, and after getting over the high temps they report I have been happy. The S3+ is the best built BITMAIN miner I have owned. (I didn't get in on the S1) If the S5+ stays on pace with the S5 with the exception of the obvious things which will need attention right away - cooling! Then I know what I bought, and I bought Batch 1. Buying BATCH 1 of anything from BITMAIN is a huge risk but also can be a big advantage depending on many variables - the early adopter ideal -

Keep to the warranty statements to the letter.
IF you aren't sure, ask BITMAIN and get in writing from them. I do not say this to say people are dishonest, I say this because misunderstandings happen, and they happen even more when the boss is in china, or the questions and answers are being translated from english to chinese, just get it in writing and e-mails are fine.
Keep your documentation from your order being placed and confirmed like you keep your bitcoins. Backed up, printed copies stored in several locations haha. Seriously though, that is your only warranty ticket and what you will be asked to send them for any warranty claim. Keep a digitized / scanned / emailed copy handy,and a printed copy somewhere else.
Just because a guy here on the forum pulls his apart on day one and re-pastes the heat sinks doesn't mean you need to do so. They are dead serious about not doing anything without their permission and people can tell many things. They put marks, stickers, etc all over the place sometimes. I do check the cable connections. I'm not dismantling the thing to do so without their permission which I will ask and I expect them to say yes. It is not unheard of at all for things to work loose between here and there, and I haven't been told no but CYA - cover yo ass -

Again, I am not saying all of this and repeating certain things to say BITMAIN is a bad company. If I thought that I wouldn't have ordered one. I am saying these things either because they are first-hand experiences, or there are clearly defined, informative posts from reputable forum members reporting the issue more than once. By reputable I don't mean they have HERO or LEGENDARY by their name those accounts are bought and sold daily. I mean people I have read things from which proved to be true time after time and as much as any online persona can have trust, I trust what they say. Some of those people only have 100 posts, and most have much more, but it isn't the quantity in my opinion. Some of them are huge assholes at times as well heh.

I will have my own pictures up when possible. Maybe customs decides they want to mine for a few weeks, not much I can do if that happens, but I know how to ship products to many countries and so does BITMAIN. My information will be facts. When I give an opinion I will state such. I tip my hat to BITMAIN on the S5+ not because it is a piece of breakthrough technology and something which will give me some huge advantage, but simply because they are the only company putting something out which we have a chance to ROI with. This whole game is a gamble and I have no doubts I am rolling the dice by having placed the order, but at least it was under 2,500 and they do have a good record for shipping on time. For the rest I cross my fingers and stay positive and relaxed until there is a real reason not to be.

As far as the S5+ making more sense than buying 6.7 or however many S5s dude was asking about.
There are several reasons for my use but I have to run and I am sure people are sick of my longass posts but a couple are the efficiency and the ability to control the heat because of the density. I didn't use a heater in my house after Christmas last year and I do not plan on doing so at all this year. I will be able to run ductwork to route the heat the way I want. Pushing or stacking the S5s doesn't work out the same for the way I have in mind without much more work. I have a bunch of S3s I will be selling soon and this seems to perfectly fit the bill. I do not like the central point of failure, and if this first unit comes in the way I hope (not expect) then I plan to order at least two more right away again, because it is a gamble. I don't go to casinos, I play with bitcoin and support the economy by buying, mining, and spending coin.

We shall see how the unit does, but I will keep a positive attitude and hope for the best. If the S7 drops in two weeks great, we have more offerings, but I am again gambling a bit because I do not think it will.

For everyone, please post up your experiences, n00bs or not, put up pictures and what you think about things. Document the good and bad. That is the only way we can help each other. I don't want 15 legendary reviews which basically say the same thing. I want to hear from Jane and Tommy how they made out with their new gear on top of the Legendary guys who have been around since CPU days. Keep it all coming!

Bitcoinware (Canada) is going way overboard with their pricing. $4,599.95 CAD

Just wow.

http://bitcoinware.net/collections/frontpage/products/antminer-s5-plus?utm_source=bitcoinware.net+newsletter&utm_campaign=abc5548e4c-new+products&utm_medium=email&utm_term=0_d5fe4ea7fe-abc5548e4c-231875677&mc_cid=abc5548e4c&mc_eid=e4aaf8d181

That website never has any decent deals, I highly doubt they get much business. It should cost around $3300 with the exchange rate and shipping

Thanks for the video. That thing is very loud. Probably good for a datacentre or in the basement. Probably not a good home miner.

let's go the other way . For my 3 x S5+ I have 6 x EVGA G2 1300W+some extra 2 x PCI-E EVGA cables and
  3X Bitmaintech  APW3-12-1600-B2 PSU .  
Plenty of PCI-E plugs for powering 3 x S5+


I do not think that you're going to make longer cables.  So that  30W  saving never has happened.

But 6 x overclocked S5  is 7500 GH/s x 0.51=3851W , not 3720W.


Why under clock ? At normal speed 7722 GH/s x 0.445W/GH  =3436W

3851 - 3436 =415 W savings + extra 222GH/s


My expenses with 3 x Bitmaintech PSU were   600 USD
EVGA  PSU-s is itself already recouped , almost with video cards mining time.


I do not think that you're going to make longer cables. However, if you do,  you need time for it . time =money


I have left  three of S5 controllers.
I am sure that they will also work in S5 + Miner if the power given to them properly.

Now, the most important thing.  I've already sold  20 x Antminer S5 for  33BTC  
20 x 1155=23100GH/s         3X7722=23166Gh/s
https://bitcointalk.org/index.php?topic=858962.msg11959170#msg11959170

Therefore, I will use the same money (33BTC)  again for bying 3 x S5+
Saving extra 1,4kW/h  per hour,
per month 1000 kW/h

save me with  six months  the price of three APW3-12-1600-B2  power supply

And no, I  did not get a discount for 3 x S5 and I do not care.
Obviously, I can not even get coupons , because the last S5  I bought a long time ago.

Tupsu, as said your self. No gain by the S5+ vs the S5.
So in the end you are going to spend more money than those 33BTC to get them up running and as I see it you would be better of keeping the S5`s and wait for the S7 being released some time this fall.
I think the S5+ is a way of "Keep the Buzz" go around the Bitmain brand when some new miners are enterring the marked soon.
Last but not least, if you fry a controller, like they do once a while, you have a complete dead S5+ while you only miss 1.1-1.3TH on a S5
No matter how you turn it around the ROI point for the S5+ is much longer than a S5

r they worth investment still?

The time and the right decisions.
That is all that counts in the world of BTC.
(I've done a lot of wrong decisions before,  hopefully purchase 3x S5+ is not one of them)

I have today exactly 100TH/s  x S5 in Hashnest. I can always sell it and buy  some S7 (If S7 comes to Hashnest for sale)
I leave only all my water cooled S5. Winter is not far away.

I do not believe that  is a simple way   to make water-cooled S5+ and get it ready before winter.


I have left  three of S5 controllers from water cooled S5 miners with 4 blades.
I am sure that they will also work in S5 + Miner if the power given to them properly.

There is a slight electricity gain on efficiency.   I will be honest though I see it back in stock and I'm having trouble pulling the trigger.   I have ran many ROI  math, and I just am not sure. 

The positives i see is it is much less space, and also easy to use 220/240.  I have a 240 line just sitting there waiting for me to put miners on it.   But I have not pulled the trigger yet guess I will think about it some more.

My biggest fear is buying it and next gen from a any of the companies pops up.   It is just hard to predict.

dunno man... i think 2 undercloked sp3x are better :o
i mean, psu in miner and less noise...
now it depends on the price of sp3x, underclock, price of electricity, etc....

The trick though is to find an SP3x. I had hoped that some might free up as people buy the S5+, but I haven't seen much availability yet.

Yeah I've been trying to get my hands one one for a couple weeks now.. To no avail, they are super hard to come by.. Bitcoinware has them with 4 week shipping delay for 2200.. Ouch

I would generally agree with you, if Spondoolies Tech sell spare parts for the normal price.
But they will not do it.
My preference is currently Bitmaintech. All these miners are easier to repair.

You guys have to understand this unit is designed with Density in mind. So for all the guys who have rack space to fill you can fit these S5+ Units nicely in a 4U Rack space compared to S5 units, obviously the small efficiency bump was due to under clocking and better cooling. In light of bitmain offering PacMic V3 and the S5+ unit at the same time this is an indication that the chip is end of life and the PacMic is to fund there tap out of there new chip for an S7 coming sometime in the next few months. Obviously the sale of all there second hand S5's is a clear sign they are cleaning out there farm to upgrade to the newer miners. Most other companies KnC, Spondoolies aren't offering any new miners to public I still think bitmain is a good company even though there focus is shifting to making gear for themselves with a side market of selling to enthusiasts around the world but make no mistake there top priority is having the most efficient gear for themselves first

Agreed. I think they are always one step ahead of what they offer to the public  ;D

I have no doubt they have a plan that is best for them.  I do suspect they also have some of the best unknown electricity rates.  I suspect the got rid of quite a bit of thier S5's during last batch.  And might have but S5+'s in for temporary hashing.

But I think their electricity is so low they likely could run a S5 easily for most of the PacMic contracts.  Although electricity price they give public on it is nothing special - fixed at 0.098 USD per kWh .

I do see uses for S5+'s.  I just see a lot of unknowns.

Few things I'd like to comment on that may help or may not help with the general discussion.  I got my first S5 from Amazon, I it's new, it's a 90-day warranty.  I think the 90 day warranty is cool. (They literally said the seller was Bitmain and it comes in standard packaging like from China)  Also Amazon is a huge company, dealing through them gives little ole me a bit of muscle for returns or other things because of defects (at least within the first 30 days).  But I definitely got screwed on price, $569 after taxes.  Most of that being just Amazon markup.  (MY FIRST mistake in bitcoin mining).  Then I got a ATX Corsair 750 bronze also from Amazon. (SECOND mistake)  After hooking the things up I was getting like a whopping 83-85% power efficiency rating.  After actually learning what an 80+ bronze/Silver/Gold/Plat/Titanium rating even means then I realized running two of these S5's as a test run (which was my plan at first before trying to turn this into a mini-business.) I would be having massive expenses in kw/h costs over that gold EVGA 1300W2 which is gold and will run two miners solo.  So it accomplishes my objective.  Luckily Amazon with their return policy allowed me to 'correct' this mistake.  I just ordered the other power supply, and am returning the 80+ Bronze supply.  Then I learn about the difference between a Server PSU and an ATX PSU and it is giving me even more food for thought, so definitely 'read, read, read' as you said.

However on the warranty stuff, they start on a lot on the little card (basically about all the ways they can shred your warranty) they give you about not making modifications etc etc.  However on their support/troubleshooting page they literally give you pages upon pages of disassembling the devices and putting them back together and adding thermal paste etc.  No where on ANY of those pages does it say those actions violate or invalidate the warranty.  I had to use those pages because I had a hash board that literally wasn't firing, and I still have 1 dead chip on the other hash board.  Granted, you're not really 'modifying' their device like with the Inline delay that you mentioned between cords.  But while I agree Email in writing direct from Bitmain Support is always the best option.  I'd think they have to grant a little leeway since they are freely offering up instructions on how to basically disassemble and reassemble their device as official 'Support Troubleshooting'.  I take the phrase 'don't modify our device' on the warranty as in don't change the core structure of any of our components  (moving them around would be fine).  But as you are trying to do, you want the CYA.

I completely agree in the future avoiding re-sellers like the plague, even Amazon.  Just buy bitcoins from exchanges and then purchase your goods for Bitmain.  In the least saves a ton on fees and that middle man margin.

(Page in question I had to use to test hash boards  Btw I got the board fixed, loose connection or something.)
https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB (https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB)

PS:  I did not take the actual hash boards off the heat sinks to check the paste.  That was just a little too scary for me right now when dealing with an alien product I just blew $500+ on.

But if Bitmain is going so far as to push you toward pages with that detailed of work for a retail consumer then you should have to have some minor wiggle room as far as doing things and not invalidating the warranty.

With regard to the comment about the stacking and heat, I also agree with you.  I didn't take any of that into account in my analysis  Same with cost on PSUs.  But I also basically am looking at the S5+ as 'made for' a data center environment.  It just doesn't seem to be home miner friendly.  But you're right.  All the other things out there, Bitmain seems to be the ONLY company selling products that offer a true ROI.

So what kind of Wattage PSUs should one be running?( assuming they are getting 3x identical PSU) for the S5+

They recommend 3 of their PSU's - https://www.bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

I would agree with going with server PSU's on these.  Unless you happen to have them paid off ATX is going to be more expensive.

3 of their psu's leaves 1300-1400 watts of overhead.


I would prefer 2x 2000 watt servers  and only have 500-600 watts of overhead.

Someone mentioned having a separate PSU for the controller board and/or at least some separate power connection to the controller board and that it 'must' be powered on AFTER the hash boards.  Do you have any insight into that?

Guys, how much you pay duty tax for this S5+?

depends on you VAT country law

 They specify they use the specs of an "ideal S5", not an actual S5.

Very big hash power (7.7 Th/s), very big (11 kg) product. Definitely not for home use. 7.7 Th/s for 1 machine is great. I would buy only if I have a warehouse/garage.

if you live in indonesia, it might between 6jt - 9jt idr.
i do the math in first page.

 Oh crap :o..i live in indonesia.

20% VAT

No. THey write:

Contract Suspension
If after 120 days, a PACMiC has still not recovered the initial capital for its user, and is not mining enough revenue to pay for its own electricity cost (fixed at 0.098 USD per kWh, calculated using an ideal AntMiner S5 hashing at 100% uptime per PPS payout), whether because of difficulty increase or BTC price decrease, the PACMiC will continue paying out for ten days as though it were running, even if the machine is turned off. If these conditions persist for ten continuous days, the contract will be considered temporarily suspended. During the suspension period, mining revenues and profit payments will also be temporarily stopped. If after the suspension period, difficulty has dropped or bitcoin price has risen, making mining possible again, the contract will be reinstated and pick up where it left off.

Q:Is the PACMiC really risk-free?

A: Like all forms of bitcoin mining, there is a certain level of risk involved. If network difficulty unforeseeably skyrockets, or if the price of bitcoin drops too much, the Antminer S5 units backing the PACMiC may not be profitable to run and be forced to go offline, in which case contracts would be suspended (possibly indefinitely) and the user may not recover the initial cost of the miner. However, the AntMiner S5 is currently the most power efficient bitcoin miner available on the market, and would be among the last to be forced to power down under unfavorable market circumstances. It is our comprehensive evaluation that the likelihood of PACMiC holders not recovering their initial cost is indeed quite low. We ask that all users please understand the risks inherent to any sort of bitcoin mining, and also to understand that there is no such thing as a risk-free product.

i placed an order for 6 x antminer s5's 1 day before the s5+ was released and paid in full, now  the bitmaintech support wont let me transfer my funds to a new order and pay the remaining difference to receive the s5+....not very pleased.

they are not about customer service I have contacted them multiple times on an RMA for 2 crappy U3's I have that burnt out and they wont RMA them for me because I purchased them through a reseller and not directly from them because they had a minimum order of 20 units and who the hell wants 20 of those? They are crap they freeze all the time and generate like 20% errors for me

Yeah i emailed them about it and this is the response i received

"Hi,
Sorry, we're arranging the shipment of S5 very soon and the order has been confirmed by financial team, we cannot change it any more.
Thanks for the understanding.

Best Regards"


IE the order has not shipped yet but fuck you we won't change your order as we already have your money.

not great for a company you just spent 2500 usd with.

S5+ is today  2341 USD

Friday, it was the price  2375 USD

Should I now cancel the order of Friday and today to make a new order  ;D

not sure if your missing the point or just trolling i ordered OLD s5's before the new S5+ was released and i would like to change my order...... i think it pretty reasonable since they haven't shipped my order and it would be very easy to do

that is common in most of the countries.

http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)


For the orders , Bitmain should have their standard procedure that involved different departments like Sales, Finance , Logistics, I think that is the difficulty to make the change,
but any way , they should write down this kind of thing somewhere to let customer know in advance.

 I want to buy today, and tomorrow I want buy  something else  for the same money. Things just do not work that way,

At next time,  buy for US dollars, and you have three days to pay.

I agree with Tupsu.  Organizations have processes in place and some are too much of a hassle to reverse.  It wouldn't be too easy to do.  

An order was made and they processed it.  I would only agree with you if you tried to change the contents of your order within 24 hours.

There is not really a huge difference between a bunch of S5s and S5+ so do not worry and just focus on what you need to do next.

They used to do that without an issue but they are not motivated to move the price you paid for old hardware to new, it's all about profit relative to customer satisfaction and they are the only game in town right now, simply not motivated to do what you are asking.

Basically it seems that Bitman found a way to sell you 7 S5's in one shot in the form of the S5+.

watching

 Seems pretty specific to me.

http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)

there is no issue we connect the hash boards & the control boards at the same time.
There are some running Videos and some of my customers already got the miners on hand from ITOP Corp (http://www.itop-corp.com)

you can check more details here https://bitcointalk.org/index.php?topic=1146965.220

I ordered two S5's Second hand and my wire went through on Friday, the 'second' day after the order was placed.  Naturally also 'right' on the weekend, which sucks.  Was because I placed the original wire order after 2PM on day 1, thursday (literally 14 hours after I made the order on their website).  They now have my order listed as 'expired'.  Now MY bank is open 7 days a week so it doesn't matter.  Not sure on their own.  I wrote them a ticket asking if they were going to fill the now 'expired' order Monday (technically now) or were going to just credit my account the money and I'd 'reorder' the same units.  I also noted that the price had actually fallen $18 USD per unit from the time I placed the 'expired' order.  

How much you want to bet they fill my original 'expired' order and don't let me re-order leaving me with a $36 credit?   :D

Update to this:  My email just came through that the 'expired' order was paid. Can't blame them for hustling on that deal.

Tupsu they state they use this calculation based on the S5.  That doesn't mean they use an S5, that's how they calculate your ROI.  They would be boneheaded to use the S5.

If I was them why the F would I use an S5 when I just released a miner S5+ that saves me 13% overhead and can run a full 7 PACMiC contracts at a time on one device?  I completely agree with the level of risk aspect you state.  But I would re-state my previous response:  You (the purchaser of these) are giving them a loan.  A loan with no hard and directly quantifiable interest, or collateral, and that they can shut down payment at a whim with no recourse.  They are getting WAY better Electrical rates than the .098 they quoted, and in all likelihood keeping the excess 3-5 cents per kw/h for themselves or to cover their ass should the market take a dump.  None of which btw is illegal.  Little shady on the ethics side, and definitely not transparent, but that's the world today, especially in China and it is NOT illegal.  So as they say Caveat Emptor.

PS:  Side note, whoever was in their marketing departments needs to be shot.  I know religion has fallen by the wayside these days, and China is officially 'Atheist', but selling your contract at .666 bitcoin internationally?  Maybe that is just Karma's way of telling people to stay away.

Just to clarify, for 2x complete 2880W PSU's to power 1x S5+ (with an extra 2000+W in power leftover...) this would be your cost:

2x Breakout boards - $140
19x PCIe cables (2 per hashboard is more than adequate + 1 for controller) - $47.5
2x refurb PSU's - $140 (can occasionally be found for less online)

So that gives $327.50 + shipping, which would run no more than $45 to the US.

More efficiently would be to run 2x S5+ on 3x PSU's (And still have 1800+W of additional power for other miners):

3x breakout boards - $210
38x PCIe cables - $95
3x refurb PSU's - $210 (can occasionally be found for less online)

Brings it to $515 + shipping, or $257.50 per miner.   All you would need in addition to the above would be C19 cable to whatever plug you are planning on using.  On top of that, you can still run 2 or 3 S5's on the leftover power from these PSU's if you lay them out correctly.

These are my prices for North America, J4bberwock has similar prices for EU orders. Both options are still cheaper than using 3 of Bitmain's PSU's.

P.S. Sloopy, as usual you are too kind, the words are much appreciated.

I see you have been posting a lot.  Are you a official reseller?  (IE bitmain warrenty is still valid if bought from you, as it does not transfer people which kills most resellers).

Just was not sure if you are official reseller or unofficial.  Thanks.

Hong Kong is out of VAT, so if you choose on webpage HK, you will see NO VAT!

And I'm sure they will kill this now that it was posted.  I'm sure it was a mistake if website does not charge vat based on website and not address.

If you don't pay vat when you should would it not cause problems during shipping?  Seems like they would catch it.

It done on the base of chinese VAT regulations. if you order miners to HK, you dont pay VAT. You can check it on webpage!

https://www.bitmaintech.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B
and it wont be changed!

Ahh ok from  your post I thought you meant just ordering from website caused not vat.  That it was not basing it on destination but website.

There are no official resellers any more and there is no qualification by Bitmain. The only recommendation is to buy from the official webstore (which is still going to be the cheapest anyway), anything else you do so at your own risk, and with them for order and warranty support.

http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)

If you Placed order for S5+ at USD2341, and now you need to cancel the order again it is USD2307 now :)

Well you've sort of just proven my point, if you buy from a 3rd party then support and warranty is via a 3rd party not Bitmain. Hence if you want to guarantee you don't get a situation like Minersource again, you purchase directly from Bitmain.

I am not defending dogie , but   he said it is cheaper to buy from bitmaintech then itop.

Now itop may not like that but that was true.

https://www.bitmaintech.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B

2307 plus shipping


so we are talking about a big mark up here.

My question to iTop is will you reduce price or keep the markup?

I payd today order, made  on Friday. 2375 USD for miner + shipping

I pay 20% of VAT. So my loss total for 3 day is 81.60 USD

id consider buying from itop since he takes paypal, but the higher price is a dealbreaker.. i can see why one would charge a slight premium to cover merchant fees but not that much

The biggest thing in my mind is if you buy direct from bitmain you have 90 day warranty.  Warranty do not transfer so if you buy from ITOP you have no bitmain warranty, unless they are lying to bitmain and send it in as if they still owned it and did not sell it.

I think, Itop  bought they  more expensively , than the current Bitmaintech S5+ price.

I lost with  my order only from friday to monday 81,6 USD

They bought them a week earlier. I do not think there is a lot of profit in the  http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)  price.

Mine shipped today as well estimated arrival Wednesday  ;D

Lucky you :P

Just a side note, don't you need three APW3-12-1600-B2's to run the S5+?  Or did I miss something?  Thought each third of a unit took six nine connections.

Yes if you buy all new you need three of them.   Some people have PSU's they have already ROI'ed sitting there.    So he might be using a mix of psu's.

Hopefully he did not order 1 psu and expect it to run.   I suspect he did not, but I could be wrong.

http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)

We provide the full warranty same as the manufacturer does for whatever products we resell , we charge a littlie bit more to cover the extra expense it may causes ,more payment options and better customer service .

What is the cfm of one of the S5+?

Does anyone want to share your daily average TH per S5+ unit?  (out of the box)

THANKS!!

How are you doing this though?  Are you having customers send to you or sending to bitmain as if it was you?

Bitmain terms are here: https://bitmain.zendesk.com/hc/en-us/articles/202661989-Limited-90-Day-Warranty-Terms-

They clearly post: "it does not extend to owners of the product other than the original owner" and as first buyer and not official reseller you are original owner.  They even warn of resellers may claim to have warranty that do not on sales "Some resellers may claim the units be qualified, however, it may not be."

Can you please show us documentation where Bitmain say's your not an official reseller yet you may transfer warrenty?

Actually i already bought another 2 PSUs for 442$ with shipping..

Question on this Dogie,

I got my first S5 unit from Amazon they literally stated the seller was Bitmain and it came from a Colorado distribution center.  It also stated it had a 90 day warranty.  While not the 'official' website I trust that counts as buying directly from Bitmain and that my warranty (which was included in standard boxing as displayed from China) is completely valid.  I cannot see a company the size of Amazon being duped in such a fashion and if they were they would take immediate hostile action toward that seller/re-seller.

I also ask this because I'm still within my 30 day 'return' window even though the machine runs fine outside the a few problem I've managed to get around.

I'm curious to see a pic of these with two of the 2880 PSU.. See how clean it looks like this for a data center environment

seems this batch is sold out?

Yes.

AntMiner S5+ Batch 1

Sold Out


And my fridays order status is
Unpaid
Unshipped
Expired

So I wonder, my order is filled or not.

the sh s5 7th batch is sold out also....hmm... the s7 time is near  ;D

No I think not ,  we will get at least 1 month of s-5+  more likely 2 months of s-5+.


BTW I would hope to be wrong about my guess.

oh...i do hope you're wrong and they will pull it out....s5+/s4 are at another scale of mining as s5/s7...let's hope they are considering separate types of buyers for these large scale/little scale mining rigs....feeling stupidly confident  ;D

The S5+ sold out fairly quickly. Id have to agree with Philipma1957 that if Bitmain has a new unit already deployed, or about to be... Their business model has always been to use the units first then begin liquidating when their next generation is ready to go in to the legacy unit's place.

Id be surprised if we see any significant upgrades anytime soon. Mining difficult has nearly stalled and will remain relatively flat until the new ASIC wafers are production ready.  Difficulty may rise come winter... But for now even mining with S3+ units is in fact profitable, which are far less efficient than the S5/S5+.

Strato 

It really is not that hard to get 240.   So I do not think they will consider it a different miner status.  I would not expect to see a jump to next gen right after selling batch 1.

I think there are a few batches to come.   It is a pretty good machine as far as specs.    I feel this miner is still one that a hobby miner could run, not all but most.  Not to mention they have mastered making this chip being used.  So they chances are can make it pretty cheap.    And selling these helps make next gen without needing a loan/investor.

I'm fairly confident they will sell more batches of the s5+, it just makes sense from a business perspective.. Why release new gen when the competition is non existent.. S5+ was tempting but I opted to get some sp20's instead for the stealth factor

Of course they would definitely list their 2nd Batch of s5+ might be today or tomorrow,as it's just the beginging  yet.

Depends, the S2 and S3++ were used to help consume the last of a generation's chip supplies and the S5+ may be the same. There's probably a finite number of S5+s planned and even if they're selling better than expected there may not be significant follow up stock. The S7 has to appear at some point.

Hi, thanks for your question.

Currently, it seems Bitmain do not allow warranty claims through resellers but we are attempting to communicate and work with them on this issue.

In the mean time, I can confirm that we are offering an ITOP 90-day warranty - the same as the manufacturer - on all purchases of the S5+ made through our official site. If you need to return a faulty unit, you can send it back to us within the warranty period and we will continue to offer this unless we can do it through Bitmain in the future - this is our guarantee.

As a result, our costs are a little higher due to extra expenses in dealing with warranty claims but we offer more payment options and better customer service and support on our full range of products.

the paypal option is nice Gareth.. but soon you will have other resellers stocking up on these offering them for under 3k.  I know Scott at HolyBitcoin is getting a shipment in and accepts paypal as well, i think he is planning on offering them at 2999.97

They are on ebay at $2900 + $60 shipping

http://www.ebay.com/itm/Bitmain-Antminer-S5-7-7TH-ASIC-Bitcoin-Miner-Brand-New-Factory-Sealed-Box-/262009233717?hash=item3d00f7a135

Can you list the TOS to your warranty?   Bitmain has a page with TOS for warranty.

Thak you for saying offering "we are offering an ITOP 90-day warranty".  I still think you should say like manufacture not same as.  With being a unofficial reseller it truly is not same as.   So you are getting better but still not there on describing it.

yeah not bad, some guy had one for 2500 earlier and it was snatched up quick lol, makes me wonder why he had it so low with ebay / paypal fees.. probably just trying to get his money back after realizing he didnt have 220v

I think it will be based on profit.  These sure do use up a lot of chips which could clear out inventory.  But also I think with current gen chips they have perfected process so if they make money I could see making chips for it and doing more batches.

Or the could wait till next gen before making more chips.   I think all depends on financials that likely will not be shared.

Well that's your fault for not paying attention to what was coming down the line from Bitmain. The S5+ hasn't been a secret for quite some time.

 There is NO BLOODY REQUIREMENT FOR 220 to run a S5+. Never has been. I don't understand why this rubbish BS claim keeps popping up.

 Yes, it might be a bit more efficient, as you get less I2R losses in the input circuitry to the PS and a hair less in the wiring. It's NOT a requirement.

There's this thing called "profit". Google it.   ;D

That would be a foolish reason since it only needs 12v DC

If you go with recommended PSU's it is required.  The PSU's they recommend don't work with 120.   

But yes you could keep throwing 120 lines to lower power PSU's.  But would not make a lot of sense.   Just look at amount of PCI-e cables it takes.  But if you ROI'ed on a lot of ATX supplies and had multiple line's of 120 close together yes you could run it.

It makes perfect sense if you're like me and have a dozen PSUs sitting around collecting dust... and there are many former miners in a similar situation. Just sayin'.

Although I'm absolutely NOT interested in the S5+ at all. It's barely an improvement on the S5. It looks to me like Bitmain is simply trying to find a way to quickly dispose of the previous generation chips to make way for the next gen.

They "recommend" their own PSU and it has nothing to do with what is optimal, only what is profitable ;)

120V PSU's are no less effective at powering this beast, so long as each PSU has enough rating to fully power each board fully (only 1 PSU per board), but 12V is 12V.  240V PSU's gain a couple percentage points in efficiency, and when you get into the larger server PSU's they require 240V, but the hardware could care less what's feeding it.

The amount of PCIe cables it takes to run would not change whether you had 9 individual PSU's or 1 4000W PSU, not sure what relevance that has to PSU selection? The best PSU for the job is either the one you've already paid for, or the one that will do the job for the least amount of money that meets your expectations (efficiency, etc) without dying.

I hope everyone with an S5+ is having a blast and I would enjoy seeing more pics and vids from others. I know you are out there!
Of course people in the US who ordered Friday are likely seeing their orders arrive tomorrow at the earliest as most show shipped first thing Monday (my time) and show clearing Alaska customs today.

I think the increase in efficiency plus what RichBC and Phil have been working on with regular S5 units has a huge potential with the S5+:
https://bitcointalk.org/index.php?topic=1151460.0
If they can find a way to do this with a variety of power supplies which is cost effective...
Show them support and some of the electrical engineers should give some opinions of what they think in that thread. I bet there are many following / lurking closely :)

This is my "second chance" with BITMAIN, and from what I have seen so far it fits my nano farm perfectly.

Good luck to all, and may the mining angels smile on you.

If you ROI'ed on a lot I agree it could make sense.   But 3 PSU's running on 240 makes a lot nicer setup.

Having 9 PSU's might work but just not the way I mine personally.   Again I can see why you would want to use them, but chances are those 9 are not gold.  If you had 4-5 gold rated PSU's that could do it sure go for it.  I personally just like gold or better getting that extra efficiency.

Yeah or two 2880w PSU's IMO would be ideal.. Less clutter and more room for additional s5+ units.. Instead of a whole bunch of random atx PSU's that one would have lying around.. Yeah it would work but it's not practical other than someone running just one in their garage or whatnot

yeah There is and I can get one ebay at 2900 with multiple discounts and six months to pay it.

so competition  will knock iTop out.

One thing to consider on ebay is fees.  By the time ebay and paypal take a chunk of sales really these ebay sellers are making quite a bit less then iTop even though it looks closer at first glance.

I still think we most likely will see another batch.   And I could be wrong on that.  But I just think they have perfected making these chips at this point, and they can use a LOT of them in these S5+'s.  I don't see them turning down profit to pay for net gen.

Then again I could be wrong and they just did one batch to deplete old stocks of chips.

*Edit iTop now shows sold out. I wonder how many they had.   We will see if they were selling from all stock or selling some and ordering them bitmain.  I don't see them holding a big stock.

Also iTop said they had units for their warranty I wonder how many units if any they keep for those iTop sales if they need warranty work.

Of course we'll see another batch. There's no way that the S5+ is a one time event. But at this late stage there's no way it will run as long as the S3 did (what was that, 6 batches?)

Here's my fantasy:

1. BTC amps back up to the $1000 range just before Bitmain announces batch 2. They price accordingly at 2.3 BTC per S5+.

2. I place my order.

3. BTC drops back back to today's $240-ish.

4. Difficulty stagnates.

5. Profit.

Don't laugh. It could happen.

Were hoping to see more batches but honestly its not a sure thing.  I think it is a good chance, but not sure.

If they were doing to get rid of extra chips we will not see it again.  If we see batch 2 we can expect to see a few i think.

I agree that we don't know for sure what will happen. We have little visibility into Bitmain's business and we're all just guessing.

But in addition to just using up current (old) chips, Bitmain will need to recoup their development investment with the S5+. It's easy for us to look at an S5+ and say "that's just 3 S5s bolted together". But the fact is that they every product, even an incremental one, costs money to bring it to market.

Whether they can recoup their costs and use up their old chips with one run of the S5+ is unknown, but I think it's unlikely.

What's more likely is that they'll keep making these until there's no demand or they're out of chips. Clearly there's demand, so if they still have chips they'll be more batches.

Further, we can look at this from a historic perspective. Has there ever been a mining product from Bitmain in the past that only had a single batch? Even the U3 had 2 batches, and it probably was a niche item.

Yes.
Antminer S3++
and Antminer L1
https://www.bitmaintech.com/productDetail.htm?pid=00020140830074550960Um75pnzg06E3

I think that we are still seeing S5+ batches, but only used miners, and not before a couple of months.

How to cool this fella is my main worries

Actually wasn't the L1 basically zero batches given that it never shipped?

Anyway, I take your point. I just hope that they have at least one more batch up their sleeves because I want an S5+ and couldn't move fast enough for batch 1.

My bet is that the recent announcement of the BM1385 chip (for the S7) will curtail some of the demand for the S5+. Some folks will wait for the S7, currently unkdefined schedule, some folks will just take the S5+ now if they can get it.

The actual announcement of the BM1385 chip, even without an S7 schedule, will likely reduce the overall demand for the S5+.

I think it will effect it and other miners.   It will all depend on when the S7 comes out.

As of right now we don't know much just some released specs.   So S7 could be very soon or could be months they don't really say much on when S7 launches.  Also we don't know price of S7.

This is the easy part.. S7 price will be 0,0011-0,0013 BTC for 1 GH/s

Hmm what makes you assume that?

S5   1.3-1.5BTC
S5+  8-9BTC
S7   ?

I doubt it will be quite that low, with the efficiency improvement.

 And who the heck figures in GH any more anyway? 8-O

Hashnest users ;)
HashPower(GHS)

Cost almost 10 BTC due to prices ill pass on that and buy 10BTC instead and wait on price make more of BTC trading than mining. If got free energy then so be it good to take a gamble but right now not for me ill maybe buy some cloud mining and take gamble that way than risking 10BTC to buy equipment wait on delays and problems on first batch. No doubt their is going to be problems on first so maybe wait and buy later.

Are you certain that using 2 is fine? The product description page says all three are required. It may be that each PCIe plug powers a specific set of chips; the 3 PCIe connectors may not share a common power bus at all as in, say, the S3 design. Without knowing the actual S5+ design, or having an actual unit to look at, saying "2 is fine" is only speculation at this point unless something more is known than what bitmain has disclosed so far.

Bitmain could confirm this here, but they aren't posting much these days. If anyone already has a unit, they could also confirm whether using 2 out of the 3 connectors works and post here.

http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com/)

What Bitmain customer Service told us was we have to use all 3 connectors for each board, As my understanding if each board need at least 382W(3436/9), in average each connector should be bear 127w@10.6A , and if it works  using only 2 connectors instead that will be 191w@15.9A for each connector , it is high risk to heat up or burn your cables if they are not good enough.   

regardless of "x" amt of batches, s7,8,9,X,11 & so on ... end of the day it WILL always be :

TOO EXPENSIVE !
-almost no chance of ROI *unless FREE or SUPER LOW elec rates*
even with that if i'm not mistaken it'll take a minimum of 4-5 months with FREE elec. excluding psu+cable+taxes+0 downtime+100% luck+PERFECT scenario
-prices will always change along with btc price
-miner issues with S&H, HW, FW etc

if you the buyer DO NOT have FREE or super low elec. rates, imVERYho FORGET about it ! DO NOT BUY. buying STOPS so does the KILLING !

most people till now really surprises me that they DO NOT:

-take into account of diff jumps or reduces bla bla bla but always put it at WORSE case scenario 
-also use a lower prediction of BTC prices for ROI calculations please
-add in shipping ! or any taxes if applicable
-psu, cables, fans, etc . . .

just ma couple of sats. $ is yours, decision is yours. atm things does look -ve

I thought Bitmain killed their entire Scrypt Miner ASIC project along with KnC.  Weren't able to pull it off, especially when some of the script coin people were warning they were going to intentionally try to FUBAR things for those units should they start shipping them with slight changes.  Not saying there aren't some small scale ASIC in capable of script mining, just they were going to intentionally make the script more resistant if major manufacturers got in the game.  Seems they didn't like the thought of all the centralization occurring.  (Not like it isn't happening anyway)

This still doesn't answer the question of whether all 3 are *required* by design, or can 2 be used if the cables can handle the increased current?

BTW the power requirements aren't as high as you mention: 3436W quoted by bitmaintech is at the wall, using a 93% efficient PSU. So the DC power to the S5+ would only be 3436*0.93 or 3196 watts, or 355W per board. *If* the design allowed the use of 2 connectors per board, this would put 178W per connector (14.8A). This isn't bad, considering S3+ units can easily be powered with 2 PCIe cables and those use around 355W as well.

They make a big deal about using 3 per board, so I would not try to personally.  They actually ship a piece of paper with some general instructions, and an email with it to.   And in all of them it made sure you use 3 per board.

So under pcie specs should it run if high quality psu with nice cables... yes.  But they make sure to tell you only run with 3 in each.  If you do 2 i'm sure it violates warranty.

so... x27 6pin pcie cables per miner....  im planning to use 3 hp 1200w power supply per miner... but.. 9 cables per power supply ..  ??? this seems hard to do... anyone knows where to purchase those 6 pin pcie cables awg 16.. ? :)

please see test here. https://www.youtube.com/watch?v=pu6qtsuw8-4

today it is $220-ish.  Tomorrow will be $200 ish

Here is my first testing with a S5+ - https://bitcointalk.org/index.php?topic=1157426.0

Finally got something big enough to need my 240.  Pretty amazing as far as footprint they put over 7T is a very small area.

Yes, it's not exactly heading in the right direction...

I've got a new fantasy now. On the new BM1385 chip announcement thread, suchmoon pointed out that the S3 was shipped a mere 2 weeks after the announcement of the BM1382 chip. If that means the possibility of the S7 being released in the first week of September, then I'm glad I missed the S5+ boat.

If there is another batch of S5+'s, they had better be heavily discounted or I'll just wait to see what happens.

If I was reading right, X28 6pin PCIE. Needs 1 for the control board.

http://www.itop-corp.com/asset/cache/__h64__/internal/logo.png (http://www.itop-corp.com)

If you use cables like this , you will need 9 of these . more tidy , main cable is 12AWG , and split is 16AWG .

http://www.itop-corp.com/asset/file/image/20150820/20150820100803_26230.jpg (http://www.itopshop.net/16awg-pcie-6pin-cable-used-for-antminer-s5-p-273.html)

Yes, this is true. You need a separate power cable for the controller, so people should take that into account in their planning.

It is crazy the amount of PCIe cables being used, but it does work great.   I used the suggested bitmain psu's and it is crazy they have pcie cables left over even after everything is plugged in.

But so far vary positive experience with bitmain PSU's.  The are not the cheapest but they come with no breakout board to mess with and no cords to mess with hooking up to breakout board.  So I was happy with them.  

My first impressions of the S5+

It's smaller than I thought it would be.  
It runs fine with 3x1300 watt psus.  
It isn't any louder than a group of S5s.  
It stays cooler than S5s running in the same conditions at lower clocks.

There's a whole discussion around how many cables per board you really need. Bitmain says 3, but if it's just a matter of cable capacity and not how the board is designed to route power, then you can probably get by with less cables as long as they're beefy enough.

Did you wire your 3 1300w PSUs to handle 28 connections (3 for each of 9 boards plus one for the controller) or did you make due with less?

If you wired all 28 with Y splitters from 3 PSUs you must have made klondike_bar happy...

I wired each board with 2 cables, one being split to having 2 connectors.  All connections are filled.  I used 3 EVGA 1300 watt PSUs.  I really am impressed with how cool it stays compared to regular S5s.  My S5+ @ 325 frequency is sitting at 59 degrees while my S5s @ 275 frequency are sitting at 66 degrees.

You can see it mining away here:
https://www.nicehash.com/?p=miners&addr=1NastyFRkeUTmMdbMmzggDVTQA6r3ibUoX&a=1&l=1

Many comments I can reply to in one quote! The reason it says 3 connectors are required is because I wrote that long ago for S5, and they just updated the numbers in the announcement without reconsidering what it was actually saying. If you've got 16AWG then you could use 2 PCI-E from the same branch, 18AWG and you'll need 2 branches and you should keep checking on it for the first 30 minutes.

Only problem I see is if something goes wrong.   If for some reason you need warranty it seems using 2 instead of 3 might be "inadequate power supply" and void warranty.

If they would care/void warranty I have no idea.   Thanks for writing it out I didn't look into it after all the warnings, but glad to know it works for those who need it and have right equipment.

ALL the 3 PCIE connectors are needed to be connected to power supply on each hash board since it is based on serial power solution and there is no DC/DC inside the miner. Including the one PCIE connector on control board, there are 28 connectors in total.
Several PSU will be needed to support the miner, anyone spare PCIE connector from PSU will be connected to control board.
But be sure to power all the other PSU first and power on the last PSU which control board is connected in the end. this is very important!! :)

If you could, please elaborate for folks.
We are an unruly bunch, and while I plan to follow the rules, it would be great to know and understand the reasoning on a couple of these points. I do not plan to debate them, I want to understand, so please take your time, and explain them for us. Most / many of us are involved in the purchasing of miners for one of two simple reasons or both:
A. We like to gamble and take a little risk to earn.
B. We have a bit of an anarchist deep down who truly believe this technology will disrupt the monetary systems.


The points I see which require further clarification:
1. Why does the controller board need to be powered on last? Is it a matter of establishing proper communication with the serial chains? Did you learn something with the S5 which causes the three modules in series to have issues?
1A. I have a follow up regarding this to say, if it is truly important to power up the controller last, then why not require the controller to be powered from a separate power source? Will it void the warranty IF the controller board is powered by a separate power source? I can see this being dangerous if that power source failed since none of the fans will run and I assume all of the hash boards will melt down.

2. The instructions sent with the miner call for you to inspect each heat sink on the hashing boards to make sure none have fallen off during shipment. How do you recommend we do so without removing the hash boards? You can't see them all by popping the fans off.


My comments on using two PCI connectors are if you do it without understanding what you are doing and measuring the current being drawn you are simply asking for trouble. Why risk it? Why take more of a chance of causing cable issues and melting down your investments or worse, burn down your home / business? We stress our cables simply connecting them. Most of the break out board designs cause stress when you have all cable locations populated and then simply sit the miner and the power supply on the shelf and connect the cables. Further consider the heat in the US and maybe wherever you live. Unfortunately for me, we aren't done with 45 c and higher ambient (heat index) days yet and these babies are going to be pushed to their limits. Be smart and use all three. It is a safety factor as well as BITMAIN aren't going to cover your warranty when you charcoal a single PCI connector on the hash board.

Those two statements are unconnected and don't make sense as a justification. If each board can still only be powered by one PSU due to cross-loading, then each board's 3 PCI-E connectors are still connected. While we don't have any high res images to see if we can see tracks, each of the PCI-Es is still in-line and *appears* to be powering the same plain. That agrees with the cross-loading argument which would mean that each PCI-E is the same as the next, meaning the only limitation is maximum load and not because it doesn't have DC/DC.

Hello Bitmain,

Can you tell me what version of cgminer you have included in your firmware, & weather it is the mainline cgminer or your own forked version?

Also, when will a version of the firmware be available for download?

Thanks.

This is a particularly important question. Although it's easy to speculate why switching the controller on last is necessary, it would be good to have it spelt out why, also is this advisory or essential? My concern, as well as the one above, is suppose there is a brief power outage everything will the power back on simultaneously, or are we expected to have an automatic time delay built into the controller power?

More importantly, if it's so crucial why the hell wasn't a time-delay built into the power circuit of the controller to begin with? Especially given most miners (think farms...) will be turning all the PSU's on at the same time with the flick of a breaker.

already s5 batch 1 pre orders sold out that sure was quick. Wonder when the next batch of orders will be available or to buy without pre order and in stock to buy. Tempted but no way in hell am  I doing pre orders ever fk that too much risk involved. Any details of when will be in stock to order as normal? or just going to be done in batches?

cough. _{look at my sig}

i tend to agree with this. if each board is drawing <400W you could provide that with only 2 cables. my guess is that it does two things:
1) prevents people from burning up cheap 18awg cables (that are limited around 150W)
2) slightly better balance of power distribution so the connector or copper traces dont fail

I absolutely understand that the official line will always be use all 3, however the technical explanation as to why you must use all 3 didn't really make sense.

Maybe someone who has an S5+ can tone out each side of the power connector pins. I think it's that simple, right?

If they're all connected with no resistance, then they're all going to the same place.

That would mean the pragmatic answer is you can probably use 2 16 AWG cables.

I have an S5+.  I am running it on default freq with 3x evga 1300 PSU. 

With the PSU's I am using; each board uses 373 watts and the controller uses 185 watts for a total of 3542 watts.

I don't think anyone would necessarily have a problem running off of only 2x connectors on each blade so long as the PSU and cables they are using are very high quality and gauge.  However;

I also don't see the point in not connecting all three.  The miner costs ~ 9.35BTC.  Cables and connectors are nothing compared to this.

That is kinda my feeling.  I can see why people with PSU's with less PCIe connectors want 2 per.  But Bitmain made a big deal about 3.

If you have a problem and it's obvious it only had 2 plugs I think they will void warranty.  So that one extra plug on each to keep warranty valid is worth it to me.

what an abomination.

maybe they know how cheap the connectors are on the boards..... made in china...
 ;D

It is actually a very nice miner from my experience with it so far.  It is not for everyone with the amount of electricity needed.  And also you do need a lot of PCIe cables I don't deny this.   But the recommended psu works great with them.

So far 1 day and 7 hours running not a single issue and running up to spec.   So actually looks good as far as miner stand point.

wut's your ambient temp & miner chip temp ?

My highest temp is 44 C the ambient temperature is 25 C. 

I have almost no errors.  Pool reports slightly higher hashrates than the miner itself.

The 1x heatsink on each side of every chip really increases the heat dissipation.  It also makes the design dependent on constant airflow. 

After my warranty ends I will try using a fan controller and testing how low the fans can be set while keeping the chips at a reasonable temperature.

My ambient temp is around around 78F which is kinda mild.   I think I have made it past most of the hotter day's in summer.   I have a lot of fans in my main mining room to help pushing new air.

One hashing blade is hitting 57c but most are hitting low 50's.   Very low errors and preforming as spec says.

I previously checked on the site for S5+ manual and firmware, but they are present now.

The manual makes more sense regarding the control board power connection, kind of...
It states to connect it to any power supply, but it is still worded oddly.
I am going to assume it must not matter, but I am at a loss why they say anything about it other than to connect it to a power supply unless there is something they are trying to tell us.

If anyone has any ideas what they are truly getting at feel free to post up.

Regarding the control board connection the manual states:
"...And be sure to connect the hash boards to the PSU first and then connect the controller to PSU"
"Connect connector on control board to any power supply"

If you are connecting the controller to the same PSU as hash boards, why does it matter if it is first or last, it will get power at the same time...
They have stated this several times, so there must be something there.

 and just because I love to repeat things that make me contemplate the mysterious statements in life I will repeat this from the manual as well:
"Higher input voltage will cause higher mining efficiency"

So how high can someone go?

I see improvements in this manual over previous generations. I appreciate there is a manual for this model.
I hope we see some clarification on the points made because whatever issue (if there is one) they are getting at with the control board power confuses the hell out of me. I previously thought that maybe they wanted the hash boards powered up slightly before the control board, but the way the manual reads with connecting to any power supply that can't be it and besides you don't want to be fiddling around getting that powered on with any delay when that many chips are putting out heat -- less fans.

I have seen an unfinished heatsink. It isn't cut out all the way. I will get a picture "from the guy" and get it posted. Overall it looks like a good unit. IT needs to be tested on a couple of other pools and ck solo to collect more data by "the guy" before anything lengthy is posted.

Did you change any fans on miner and where do you keep your miner? Air circulation looks like enough  :)

As far as the power I think you are worrying a little to much on it.  I think they designed controller unit to look for blades being powered on, so blades being powered on is a good thing.  If for some reason it the controller is booted up first and didnt work just reboot it :)  I have had 0 issues with mine.

As far as power getting more efficient not sure.  220/240 is more efficient then 110/120.  But I suspect almost all have it on 240 and not multiple 120's.  But not sure how far they are thinking.

What do you mean by you have seen a unfinished heatsink can you take a picture?

well if world was perfect into 4 months the roi will come and some eletrecity costs too

Yeah, I have a pic and will put it up tomorrow... err later today. It is a heatsink which wasn't completed but it was installed anyway.

I agree regarding the power. When they make such a big deal about something by putting a different blurb about it in every announcement, manual, etc then it would be great to have some clarification.
I've e-mailed them to ask. Things like that make me want to know why. Part of playing with stuff like this for me.

I've seen 0 problems other than a couple of minor things. As long as it hashes well there is certainly nothing to complain about. The speed and density are fantastic and it runs much cooler than an S4 in the same space and ambient temps.

EDIT: Looks like batch 2 is shipping.

I wanted one of these before the new chip announcement. While I'm still tempted (bird in the hand), I'm probably going to wait for the S7.

I take it back. This is probably a scam. See my next post on this thread.

Yeah, I saw that link this morning too, but now I think it's a scam.

Note that the text of the link above says "bitmaintech.com", but the actual domain is "bitmaintech.co". Looks like "bitmaintech.co" was registered on Friday August 21st, 2015.

The main bitmaintech.com site says nothing about batch 2.

I first saw notice of the last batch on reddit, but the link to the article was also likely a scam. The news article link on reddit was "bitcoinmaqazine.com" (note the 'q'), not bitcoinmagazine.com.

Be careful. This is probably a scam.

The question is did dailey123 intentionally obscure the above link, or was it an innocent mistake?

There's no mistake!

If you put this true link: https://bitmaintech.co/productDetailc054.php?pid=0002015081407532655504JMKzsM067B you must edit for change it for intentionally obscure...

Do you guys really think this is the last batch?

woah huge post.. so this guy was trying to scam others with a fake bitmain site? lol thats pretty crazy

yeah and if you signed in he has access to you bitmaintech password ,not good if you have cloud with them.

Sadly people will to to extreme lengths to scam people.   I did not click any of it as I don't want to possibly get infected or other bad things.

But if you clicked it change your password.   The good thing is I think you have to accept changes on payout in email.  I could be wrong but I think email confirms it.  So if I remember right that would help stop him.

When in doubt, try and login in with completely bogus Id/Password. I did so using offensive words at every usual place, it was completely happy with what I put in. I always wonder if the scavenger of the Id/Password info recognizes what I've told them to do.

LOL thats hilarious.. it accepted total bogus user/pass combos, he/she is probably looking at his logs and saying wtf

Since I am an English speaker, I use English words. Perhaps some folks would like to try offensive/stupid words in another language. Give the poor scavenger something to read. Bonus points for those folks that can blend multiple languages together.

Whats even more sad than that if they just put half the time they waste into helping people they might actually be able to make something of there life.. But sadly they choose to be the dirt on the bottom of our shoes..

How long has it been now since BitMain has had S5-anything to sell?  I am starting to worry.

Shit I think I log with this website. I changed my password on bitmain but that suck.

I'm not worried but I do wonder if they are done with the S5 gear.  The S5+ really is a nice miner lots of power in not much space.

But now they announced a new chip it's hard to say what they are doing.    Everyone knew this could be a one batch to use up a lot of old stock of chips.  It's looking more and more like this is true.

yeah it seems more and more likely that this was just a one time batch to clear out existing chips

What seems odd about that is that Bitmain had to engineer and test a new hashing board, as well as a new controller with lots more ports for hashing boards and fans. Wouldn't it have just been easier to build more S5 miners until they ran out of chips? Seems like a lot of work to just run out the existing supply of chips, as well as support the S5+ product for some period of time after it's produced. It seems that S5+ didn't have to a "triple wide power sucker", it could have just as easily been a hashing board improvement for the existing S5 controller and frame.

Could the S5+ have been some kind of prototype that became a product? If the BM1385 chip had the same layout as the BM1384 (i.e. the S5 chip), then I would speculate that the S5+ was a prototype for the S7, but my limited understanding is that the boards for the BM1384 and BM1385 will have to be different.

We know they got rid of a LOT of chips through this product that is for sure.   Also they were selling used S5's trying to clear out their data centers.

It could have been a prototype for all we know.  It is a good design for all we know they had them in their data centers and decided to open sales to public.  We just don't know it's all speculation.

As a home miner, I hope that the S5+ does NOT portend the design of the S7.....

I am a home miner aswell.  I hope it does as there are many benefits.  Having so much hash in a little area is a very nice feature.

I don't expect them to follow this design for the S7 as I think they will make it run off 110.   But I honestly hope S8 or what ever it's big brother is follows this design.  I was scared of 240 at first but after I love it and hope to see more models that use it (yes I know 2 120's could run it but it would not as common).

It honestly is a great miner and has lot's of advantages.

Given my home situation, my single SP20 is a "tolerable nuisance" at well under 500W. A 3KW screaming S5+ would not fly. Just like I don't expect an SP35, or S4, or numerous other miners would fit my home situation.

Maybe I am in a shrinking minority.

Honestly S5+'s were a better built unit.   Instead of plastic sides with one fan, the metal unit with push/pull fans.  I see your point for some on amount of electricity.

But I think you will see more and more in this category.  For better or worse mining is changing.  I think rack mountable high electricity units are where were going to.  But S7 likely will be a 110/120 machine as Bitmain has not seemed to leave this on initial launch of chips.

Disagree that S5+ were a better built unit. Simply counting Watt density per machine (watts per fan) you can see that airflow must be at least double compared to S5, and everyone still remember S5 often failing even at good conditions with stable internet. I can accept that the unit is comparable, since they increased CFM by doubling fans and eliminated "hot spots" using heatsink for each chip. The biggest disadvantage is huge CFM with huge noise and also more sensitive to dust. S5+ has been built for huge datacenters to save space and cables. It is just well done to fit one standard 220/16A power line.

These seem to be tested better.  Honestly the fail ratio I don't think we have seen someone post one single bad board heck even with a single bad chip even.  I am surprised at that honestly.  I have had a network outage and zero damage to unit, so that is good.

Inspecting it once I got it I personally did not see any signs of use or wear.  I was expecting them to see they had used them but it appeared new.  It honestly is a good design and just works.  

But I agree with electricity requirements it is not for all people.  There are some that a 16A is to much for, and that is understandable.  And that is why we keep seeing a 110/120 unit with initial chip release as there is a market.

Hi guys got my s5+ unit got to say overall very disappointing, powered up my unit and it caught on fire, half of the heat sinks have fallen off during transport from china would have thought that bitmain would do a better job now im waiting for a response from them.
https://i.imgur.com/stC2yYR.png

My last S5+ was with broken fan, But I do not blame Bitmain for that.

broken fans is one thing but having the unit catch on fire and heat sinks not suck on with enough thermal past is another thing keep in mind these units are valued at $2300 usd

There need not be a single drop of thermal grease.
They are glued with thermal glue.
Edit. Older version is still with termo pads.

I bought them 3pc, so I know very well the price.

I am surprised it seems like a few want to have a big flaw.  But the S5+ really is just a better designed unit then the S5.  I have no doubt it cost more money to make the casing and fans, but it was worth it.

Sadly I think good chance 1 batch was it for these guys.  Guess we will see if they use design again with new chips hopefully one day.

Interesting. I tried honeypotting with a new empty account and there was no attempt to log in yet.

i belive that the fact that the roi can be over 1 year its a very unusuall to invest even just for staing with the miner after and got deprecated over 1 year but ok if does not have those erros that you claim into the po box trasportations it can be good not for me im slow low investment but i find appealing to mine btc at the speed of 7.2TB

New Day. New faulty S5+ miner  board.

What impact does the one missing Asic in string design?
When I lose the entire blade?

https://i.imgur.com/IHHOYov.jpg (https://i.imgur.com/IHHOYov.jpg)

1 asic lost, 1 asic with x

You do not lose the entire blade every time.  Depends on how the chip was lost or what chip were lost, it could be a total loss, but not because you lost one chip doesn't make it automatically lose the whole hashing PCB.  Yes it can be but based on your Miner Status Page, you did not lose the whole hash PCB.

Please follow the warranty document included with your S5+ shipment.  

FYI: https://bitmain.zendesk.com/hc/en-us/article_attachments/203226375/S5__brief_user_guide_and_warranty.pdf

(Please do not shoot the messenger...  Please!!!)

In general if a chip fails you will loose all of the chips after it in the chain. The chain continues to work because there are two chips at each stage plus a resistor in parallel with them, this keeps the chain powered, however dependant on the fault the other signals are not passed through. So this could be last chip in the chain or could be any chip if the chip that is not recognised is still passing the other signal through.

From my 3 x S5+ working normaly only one, as it should be mine.

Last miner was with broken fan.  and it turned out that there was a not working blade.

https://i.imgur.com/2SuSet5.jpg  (https://i.imgur.com/2SuSet5.jpg)https://i.imgur.com/VJO0lVE.jpg (https://i.imgur.com/VJO0lVE.jpg) https://i.imgur.com/4SZQqzU.jpg  (https://i.imgur.com/4SZQqzU.jpg)https://i.imgur.com/vvDtqzu.jpg (https://i.imgur.com/vvDtqzu.jpg)

I took the fan from another S5+ and  A broken fan-sided last blade  is  broken.


https://i.imgur.com/CIIZ3Et.png (https://i.imgur.com/CIIZ3Et.png)

At first it was only 1 missing ASIC , like the the second miner.

https://i.imgur.com/6pJ87Fg.jpg (https://i.imgur.com/6pJ87Fg.jpg)

So I already know that a single ASIC loss may be the loss of the entire blade.

Therefore, I paid 7500 USD and got
one just [non]broken miner, that can immediately break one blade  
one just broken with transport ,
and  one 100% working miner.

All they had mined for at least a month, if not more, before selling

3. In some cases, the warranty will be void, but Bitmain can still do repairs at
your own expense if requested. The following events will void the warranty:

a. Customer removes/replaces any components by himself without receiving
permission from Bitmain first;
b. Damage caused by electrical surges, lightning, or inadequate power supply;
c. Burnt parts on hash boards or chips;
d. Miner/boards/components damage due to water immersion or corrosion due to
wet environment.

Anybody looking to buy an S5+? PM me.

you got mp! i mean pm! ;D

Anybody of S5+ buyers who will not use a S7 coupon or have extra-pm me if you can spare (for a price, if needed).
thanks

I am looking for one coupon for s7 User ID: david99  Thank You

I'd consider it to do a review I guess. I don't like missing models out, PM me.

I think my S5+ controller has now died. I've operated dozens of S5's for a LONG time. This is the first time I've run into this issue with a controller. I even took special care with my S5+ to make sure it was run in an extra cool environment. Very disappointing.

Then who is at all qualified for local EU warranty?
And what does this mean?

That is not good to hear :/.  Good thing is they should have them as S7 appears to use same controller.

I still have had no issues.   I do keep have a decent amount of CFM from fan's pushing air through my miners.   Not sure if that is making any difference but I like it and it's made my other miners make it through summer mining.

Good question I was not aware of EU warranty center.  But I'm sure they would make lots of EU happy if they had this.

But the anwser is that means he has to deal with China warranty I believe.  So it's dealing with shipping there most likely.

You're right.

Yes, this is obvious.
But what does it mean if you get direct EU warranty?



I only heard some rumors about a EU office but got no verification, so this is interesting...
BTW: In the past I have offered to help them with EU based warranty stuff as we have done for rockminer. Most EU warranty
and distribution was handled by us.

You will need to email bitmain on this on.  I do not know of one or heard of anyone using one.

So either they made a slip of togune, or possibly we will see one sometime put in EU.  But you will need to ask BM direct as none of us are going to know this.

Is it possible to just order a new controller?  Seems like that would be cheaper than waiting weeks for a response to my RMA request, mailing this monster away, and then waiting god knows how long to get a new one.

I think it depends on who you talk to.   On S3's they originally would sell them straight out,  but later made it where you had to do a RMA.  On this it was since they were able to fix most of them, and sell again.

But it's worth a shot to ask.  Just tell them you want to buy and not mess with.   If they do it would be quicker and no having to ship old controller out.

Hopefully I can get ahold of someone.  I put in a ticket yesterday.  Would be great if the controllers were cheaper than shipping...

On the other hand, if there were 3 people who were interested in buying individual S5+ 1/3 units, and had their own controllers, I'd also be open to that option.

Please let me know if they let you buy controllers and if it's a fair price.  That is a interesting idea for down the road if I sell.

Having a controller for each one would make it lots easier to sell.  Finding a buyer for entire unit is a little more limited audience.

You probably only need a new BBB from some used S5 miner and S5+ firmware

I havent opened mine up.  Is it another miner that is not using the SD card?  Looked empty in your shot but thought I would check to make sure.

Thanks for all your good information you have shared.

I also have not yet been opened S5+ controller.
But he also works with S5 software . It will see only four blades.
S5 controllers work with S5+ software.
From this I conclude that both BBB are identical or interchangeable.

Yesterday I asked Bitmain if I could buy 2x more controllers for my S5+; they said they don't have any spares.

It could be they just don't want to sell the controller board by itself.  It has some nice features others would like to get it by itself.  Also S7 appears to use the same one..... so I think they brushed you off nicely.

But most likely they just don't want to sell separate.  We know they have them there for warranty.   So chances are this means if you only replacement where you ship in old one.   

Tupsu I want to try using an S5 controller with a 1/3.

Can you tell me which of the 4 pin cables are 12v and which are ground?

Thanks

Two are 12v and two ground. But I do not remember which is which. ++-- or --++

The next time you are near the miner can you trace the cables from the pcie end to the 4 pin.  This should easily show you which is which.

Mining revolution 😜 Upgrade our existing S5 up to 2,9 TH/s 😜

You can run it with S5 controller  (18 pins)  and with S5 or with S5+ software.

You can put up to 2 x S5 + boards to work with the existing Antminer S5

One Antminer S5  and one S5+ single board  working together at 2 TH/s see picture below[/b][/size]

Thanks for the information.

Are you using the S5 or the S5+ firmware on the S5 / S5+ combos?

S5 firmware , because S5 + firmware does not support  the function "Customize the fan speed percentage"

That sound pretty tasty.

Do you have a picture of of Frankenstein (2xS5 + 2xS5+ Blades)? I'm curious as to how you place the boards to other heatsinks so that they get cooled.

No pictures.
My  setup work in the S5+ housing with  2x S5+   fans.  Total 3x S5+  blades. One runs with separate S5 controller.

2 other S5+ blades are connected with self-made long S5 data cables to normal S5 miner controller.


S5 cable is only 8cm
and S5+ data cable is 16cm long.
My self-made long data cables is 22 cm long.

frankenstein s5+++ :o
 ;D

nice work!

I see, i only have S1 housings. But maybe you could sell those blades as an upgrade kit :)

If you werent in the europe this could have been interesting for me.

Hi guys! Does anyone know what is the model of the adhesive thermal paste Bitmain use to stick the heatsinks? I want to see if the heatsinks are dropping because of the heat. Bitmain states that the miners can work in ambient temperatures of up to 40 ºC and the highest temp they might have had is 28 ºC (room temp), and still, I found 4 boards with heatsinks dropped…

I am also having only 1 out of 3 S5+ working perfectly... I have got another 5 antminers, I started having troubles with these units. I really regret my decision of buying these S5+´s…

the more complicated, the more complex, will result in a machine prone to more defects....
lucky notlist3d! ;D

Do not fix it yourself. Send it back to bitmain.

I did get lucky mine is still working great.   Sadly power company did a upgrade and I lost electricity during it, turns out they like to work on wires that are not live :).  But if was not for that I would have hit 30 day mark of working and not having to change anything.  I think 24 day's was highest I got on getting pictures of it.

And Ferol is right about fixing these.   If you do anything even fan mod you kill your warranty now day's.  So make sure you get bitmains permission before trying to fix it.

Yeah, I’m about to send the damaged units back to China, I just wanted to know what kind of thermal paste/glue did they use, its a limited time warranty. I feel very disappointed about these units and the glued heatsink design; they just wanted to get rid of the remaining chips before releasing the S7 model…

Just received my new beaglebone ... i'm having 4 green light and 1 red on the daughter board .. still no power on the beaglebone ...

anyone has a troubleshoot HOWTO on the daughter board ?

Hard to believe I have receive a DNA from Bitmain :/

They have not really released any documentation that I know of that would help on troubleshooting on the daughter board.  I hate to say it... but I think you will need to ask them for help again :/

I am suprised they shipped DNA.  Makes me wonder if they were wrong originally on their guess of what was not working.

I told them i have 4 four green lights (D1 to D4) plus a red one at D5 on the daughter board.

Fan running slow...

I would be surprise the BBB is DNA too.

That is pretty specific seems like that would help them on finding it.  Sadly you will have to contact them, you cant do much of anything now without ruining warranty.

To bad they don't compensate for downtime.    You might ask nicely for them to ship next part out without you having to ship parts back to make it faster, not sure if they will do it.  They might want to look at entire thing after it all, which would suck.

My bad i posted this in the S5+ section and it's for a S5. ! Sorry guys :(

Notlist3d thanks for your feedback men, appreciated !
