Calculation Board
 For the new cooling system design , The S5+ uses individual tiny heatsinks and uses all aluminum body, it gives higher heat dispassion ability and reduces the weight at the same time.

Control Board

You can now purchase from ITOP Shop http://www.itopshop.net/world-biggest-miner-antminer-s5-bitcoin-miner-77-t-3436w-p-271.html (http://www.itopshop.net/world-biggest-miner-antminer-s5-bitcoin-miner-77-t-3436w-p-271.html)

Is this for real? I would like one if it is real. I went to your shop it is over 3200 needs 2 psus. I think it is not price correctly.

With shipping I am near 3400. I need psu for it and I know that shipping into the USA at a price over 2500 causes a lot problems.

I think I will pass.

Wow that's really nice!!

Your photos fail to show how it is powered making it less likely it is real.  You also do not show a working unit.

Looks like there's 3 PCIe connections per hashing board and one on the controller.

If this is a fake, it's a pretty good one.

However, I'm surprised that the announcement comes from this user rather than from Bitmain themselves...

NO It's not fake;),

I have ordered drones miners and things and follow ITOP and have done a good amount of business with no issues. I can assure you it's not fake.

looks like you may be correct so it would need 3 evga 1300 psu's
 

still pretty costly 7 s-5's =  2950 shipped to the usa  .   I can get 8050gh from 7 s-5's .

 so I save about 500 in price  and get 350 more hash..


   watts would be more about 4200 vs  3400   but 800 watts cost 58 more power wise each month so I spend the 500 in savings in 8.6 months.  So getting this machine

at this price would take me more then 8 months to be better then buying s-5's


I left out the 2500 price barrier causing usa buyers an import problem.

I left out the extra hash the 7 s-5's do.

So this deal is not good if it is real.  

Needs to be about 2450 shipped to be better then me getting s-5's   I will end up getting s-5's to avoid the shipping import issue.

Pretty bad ass unit, but like philipma1957 says it's hard to justify that price with the additional costs of importing to the US and psu costs.

yeah I like it but it is over priced.  and if this is really a bitmaintech s-5+  why did they not list it first?

I would think it is a  loud machine 6 fans for 3400 watts will need serious speeds.

I would imagine it is a screamer! And, I guess it is similar to the S3++ which unless you live in China there is almost no way to know about them, or get your hands on one. 

For all we know Bitmain has been implementing the S5+ over a couple months, and that is why the used S5 units are being sold off completely now.

yeah it is perfect for the bitmaintech farms

They can use 2 of their own psu's to run this

This would take the place of six s-5 machines in the bitmaintech farms it uses 3445 watts vs 3600 watts. It gives 7700 gh vs 6900 gh

I don't really see the upside, the performance ratio is in the vicinity of S5's albeit more compact. Sound like the same chips but a better board. I think its too much heat packed in so little space. People kept arguing me but i still believe this is far from a home miner, and its not much of a upgrade. Its just centralized mining optimized.

I agree this gear is designed to work in an s-5 farm

Forgetting the import tax issues if I got this unit I need to tear it down and alter the fans since the sound is too loud.

wow...awesome is really nice hardware sha256 miner
 :o need 3400W Psu, and cost $3,300,  ::)

......... Why would another company be launching a bitmain product? ....

I asked this here


https://bitcointalk.org/index.php?topic=902305.msg12083099#msg12083099

Wow this looks pretty badass, might be what Bitmain has been hiding up their sleeve, makes sense they are starting to hit the market from a third party as they've likely been mining in pro farms for months already

It's fun to see but if this is really from Bitmain I'm very disappointed.  Waisting peoples time with new + models after months of waiting for S2 upgrade kits which were announced.  Not very ingenious slapping oc S5's together but interesting none the less.

SCAM SITE !!!!!

http://www.scamadviser.com/check-website/itopshop.net

What makes you to say it is scam site ?

Your website says there are currently 2 in stock.

Please take a picture of both units with a piece of paper with your username and date written on it.

If you cant do this then your website is a scam and Blockhunter is a sock puppet account as quite a few of his posts seem to be randomly telling everyone how great your services are.

Edit:
@itop_james I see you online but no response for some reason  ::)

Yes , we will make a complete review with some pictures of the machine is working when we back to work on Monday , but will not take  pictures as you instruction that write usename and date , thanks.

It's up on bitmain.cn (http://shop.bitmain.cn/goods.php?id=47) as well as this (http://www.liyingfei.com/antminer/antminer-s5-plus) Bitmain related site.

yea I'm not a sock puppet and james is not a scammer. And if you can read I said I follow this company. So if your pointing out the obvious great job. But your detective skills are weak. It's real and so am I. :)

it is 19000 CNY that is 3058 usd

This price will cause you an issue if you ship it to the USA.

Anything over 2500 USD has import problems.

So if it is real and it looks real it simply costs too much for a home miner.

Too bad.

Needs to be 2499 just to avoid import tax issues.

6 overclocked s-5's = 6 x 1300 that's 7800gh  at 600 676 watts each you are doing  3600 4056 watts

this does 7700gh at 3400 watts    a savings of 200 watts

No offense intended but if you have been here a while you'll be aware of the scams that take place.

Will be interesting to see if those pictures get posted monday as promised.

they are on bitmaintech's site and they are cheaper  then itop is selling them.

no offense taken. If you would like to check out who I am you can follow me on Twitter @wearewewill you can see pic's of drones I got from james for my nephews. Or check out this article about me here.  
http://us.newsbtc.com/incakoin-nka-can-approximately-double-its-existing-amount-of-coins-every-90-days/

Repeating myself once again this appears to be a real product.

It cost too much.


if you live in the USA and do imports over 2500 there is a lot of extra paperwork.


  Two 3 piece orders of s-5's  cost = 1288 + 1288 that is 2676 shipped   for the s-5's

the s-5+  is 3378 shipped


one does 7800gh at 4056 watts

other does 7700gh at 3400 watts


so to save 656 watts  you pay 702 usd   

two separate orders of s-5's no import duty issues
1 order of s-5+ import duty issues

656 watts at 10 cents is 48 bucks a month so in 14 months you make up the 702 price premium

This item is absolutely senseless to buy at current pricing.


Now maybe the s-5 goes out of stock and the only item offered is this one.  When that happens then you won't have a choice.

right now just buy 3 s-5's and order 3 more the next day. 

No. Even at 220V  6 overclocked s-5's  need more, as 3600 watts, if you use bitmain PSU-s.

yeah I thought I corrected that.


at 1300 1 s-5 does 676 watts x 6 = 4056

I have it correct here
https://bitcointalk.org/index.php?topic=1146965.msg12085674#msg12085674

I went back and fixed it here

https://bitcointalk.org/index.php?topic=1146965.msg12085484#msg12085484


so this big new s-5+ is 7700gh at 3400watts   and 6 over-clocked s-5's are 4056 watts

you power savings is 656 watts about 48 usd a month (at 10 cents a kwatt).

price is 700 usd more  which takes 14 months  at 10 cents a kwatt.

Basically it is just plain over priced.   

 If it cost 2675 shipped  instead of 3378 shipped   you could argue it was better. Since you are paying the same and saving 50 a month in power.

The problem of it costing more then 2500 would still exist. You get import duty issues over 2500.

 

 A Spondoolies SP20E can achieve the same efficiency as this unit claims, which is noticeably better that the S5.
 The new Sfards unit can achieve even better by a bit, though the reliability of that unit is looking distinctly "early Gridseed".

 Is there a reason you insist on selling these in a no-rack-mount configuration despite their rackmount unit sizing? Would make more sense to sell them as individual S5-sized units, NOT as triples.

 The price is WAY too high to ever be able to ROI on the unit, unless the rate of difficulty increases drops to under half of this years "so far" rate, or bitcoin value kicks up a LOT.

 The "cooling" design is a sad joke, the airflow is way too constricted and passes over WAY too many heatsinks to work worth anything for the last couple rows of chips in the air flow path. "push pull" fans do NOT double the airflow, the ONLY thing they do is reduce the back pressure allowing a SMALL flow rate increase.


 These comments assume that the unit is actual, not just a good photoshop job scam or a picture of a prototype concept that is a REAL BAD IDEA at best. <edit> just saw Bitmain confirm the unit is real, which doesn't affect my other comments.
 0.45 efficiency is not enough to make this unit viable for a significant length of time IF AT ALL past the block reward halving next summer, any more than the S5.

 If you wanted to make a unit that WAS viable past the halving, run 20 chips per chain not 16. That would unleash the REAL efficiency potential of the BM1384 and might actually rival the NEXT GEN units that are on the way from Bitmain and Innosilicon (I discount BitFury and KnC as neither sell to end users any more).

 I would anticipate the S7 finally being retailed within a week of Bitmain selling out their last used S5. Possibly up to a week before, more likely the same or next day, possibly as much as a week later.

 The only way I could be more certain that the S7 is in production would be to see operating S7s in the Hashnest farm or in Bitmain's manufacturing place in person - they've got to be replacing those used S5s with SOMETHING after all.

I can't wait til Monday to see these review pics and stuff itop will be posting hopefully

Strange way of unveiling a new product, learning about it from the distributor.  Seems Bitmain reached deep into their pockets
and pulled out a bunch of lint. :D

Maybe Bitmain has no intention of selling this themselves, they could've been special gear for larger farms who paid big $ to get the most hash / power they could squeeze.

Now some of them are unloading to make way for new stuff?

Most likely this was a unit to be sold domestically as a smaller batch to finish off the chips, will see.

It is on bitmaintech's China website.

Now look what all the talk about this monster has done to the price of BTC .....

wow were getting closer to my big in level.

I was offered one at a great discount to test from ITOP. I'm pretty excited to try this out. I will keep everyone updated.

so can anyone confirm this is a legit product or not? is this the only website to buy this from?

You can also try getting it from Bitmain's Chinese store: http://shop.bitmain.cn/goods.php?id=47

Yeah confirmed, was intended for the domestic market only though.

I think it would be nice if you give us a DB.  Sound reading. I would love to know if it is over 75 db

Dear customers,

The S5+ is now opening for sale in Mainland China market(as some one has already found on the bitmain.cn), and it will be available for sale on global market next Friday. Then you can purchase the S5+ on our official website of bitmaintech.com.  


We recommend Bitmain customers to purchase our products on our official website, unless you have your own particular reasons to buy from other channel, for example, you known about the seller quite well, or you trust the seller, or the seller can provide very good support to you.

how about the s7?

I think it will be after sept 30th

But my sources are not the most reliable

Wow thank you for letting us know, that puts an end to the speculation

I hold thumbs for the S7.
This miner is out of the home miner hobbyist market with those power requirements. :-[
 

However this brings the question; Does this mean we no longer get an announcement on the alleged s7 next month-ish?

I wouldn't mind that much, considering if this "was it", just mean what i have right now will stay effective for a bit longer. But i would like to see a newer small factor miner soon.

the 3400 watts its like 36 cents expensive per hour in consumption needs at least the 0.02 BTC per hours getting in mining yip seems nice the every TH gives you like 0.01 soo might even be 0.07 to just spend 0.02 its 250% profit a day like 1 BTC per day and spend only 40 dollars per day seems like a 160 dollars porfit per day till its pays the miner
let me see things right the all mining power its like 10 PH and to get a 10 mins 25BTC soo its 150 BTC per hour and 4000 BTC per day if you have 7,7TH you get like 4 BTC per day max and not the 1 BTC but you need a bit like to get the full 1000 dollars per day and pay the miner.
if the all net its just 10PH

 Hair less than that at current difficulty, but close. That WILL drop over time of course. PS - that's per DAY not per HOUR, you'd be looking at ballpark $30/day income NOT $300ish per unit, at current difficulty and bitcoin price.


 I AM curious why this unit isn't designated as an "S6" rather than a S5 varient, as the form factor is a LOT closer to rack mount than single.

 My main issues with the unit are:
 (1) It should be a single size unit like the S5, not a "triple", as the flexability is nonexistant and the cost increment per unit is HIGH.
 (2) WAY too expensive, chance of being able to ROI this thing is pretty much ZERO unless your electric is VERY VERY cheap (UNDER 5c/KWH).
      It might be viable if it was under $2800 but even at that price WITH shipping it would be marginal.
 (3) CUSTOMS ISSUES at least for US customers, anything over $2500 gets a lot more paperwork needed AND a lot more scrutiny and probability of customs hassles
 (4) the efficiency isn't enough better than a S5 to make it worthwhile, especially at the major price increase over equivilent hashing power out of S5s
 (5) the thermal design seems VERY iffy given the increase in power density and the much higher airflow restrictiveness.

 If it was a 20 chip per string design, the efficiency WOULD be a lot better (still not equal to various claims about next-gen stuff I've seen, but at least competative with them), the probability to ROI would increase a lot IF the price was the same or lower, and the heat issues would be a lot less.


 Personally, I have ZERO interest in this unit as designed and priced. I'm still waiting for the S7 or the announced Lketc unit (Innosilicon A3 based most likely).

Well it is smart to put individual heatsinks on all the chips, I am surprised they didn't do that originally with the S5.

Well, those individual heatsinks are on the backside of the chips, but, aside from the increased weight for shipping, I'd have prefered the S3 type top heatsink on the reverse side rather than those little things.

Do not think. Look at the image .

http://www.itop-corp.com/asset/file/image/20150808/20150808093917_81008.jpg

So the only one who has these sexy beast machines is ITOP until Friday.  Could they be sold out by then if they are being offered in China?

Actually, I am right and wrong in the same measure.... seems like they have individual heatsinks on each chip as well as on the backside of the PCB. That is some strange contraption there ..... well, from what we've become accustomed to from them.
In any case, unless they offer these beasts modularly, I shall not be in the market for them (both on price and power requirements).

Yes, they have done so. A few s5's with small heatsinks went on the market. It has not increased shipping costs. I think it was a test series before the development of the model s5 + and perhaps before s7 if one appears.

Aahh ... thats where I was wrong too. The S5 has small heatsinks on the rear and the large heatsink on the chip heads. From the picture of the S5+, it looks like they've done away with the large heatsink completely and they have slightly larger individual heatsinks on the chip heads and the smaller heatsinks (similar to what some S5's shipped with) on the rear.

Vorta modified his s5 in this way, but also Bitmaintech did a short series s5 modified in this way: https://bitcointalk.org/index.php?topic=902305.4500
Rabinovitch confirmed this in Bitmaintech .
Please note that a so modified s5 has a higher heat capacity . Slower reach appropriate working conditions. The use of such heatsinks reduces the dimensions of the device and/or reduces the level of HW errors.

I want just the center unit and the controller for 900 shipped.

I want to buy add on left or right sides for 750 a piece.

That's genius. Might lose a few pennies on the shipping but you'd avoid so many issues with imports.

I wonder if this is something that can happen.

There are many indications that this may be a mythical s7 . That would be good news for everyone. Despite the progress in reducing the demand for energy is still insufficient.

But the s5+ just seem undervolted S5 stuff, with more chips. If bitmain labeled that S7, that would be hella inappropriate. They might have came up with the S5+ in the mean time since that's good for their market and mines but its not really a new generation, is it?

Truth and PCB redesigned. But it has not yet seen even the really serious announcement of a new device. Until now everyone was talking about s6 not s5+. It is true that without the new ASIC will not reach newer heights here . In addition, with increasing density of elements will be increasingly difficult to work without air conditioning .
In case of new device with the new chip is a fear that will be put up for sale with a delay .

I do not think that Bitmaintech has the technical resources to bring 2 or 3 new devices operating on them in parallel. Personally, I would be focused on the most promising solution. A solution used in the S5+ seem to only an intermediate step.

And here it is thanks ITOP

As soon as one of these are in my possession I will let everyone know.

I am very curious what we'll see, what are the possibilities of overclocking and what difficulties in supply and stable operation . Maybe new software?

no no no  I got a great idea.

let then sell the s-5+ center piece as a stand  alone.

does 2550 gh at 1150 watts.


you can buy add-on left right s-5+'s if you wantin a week or two  or you can wait for an add-on s-7 say late sept or early oct.


this is a really good idea.


I really think they should do this.

genius idea  8)

I think they shouldn't bother with the add-ons, just sell the single by itself.

 Might be interesting though if they sold an add-on with 2 boards to attach to an S5. It DOES have those 2 "spare" connectors on the controller board.....

I dont think they will though, aren't these geared towards data center ops?  Maybe after they see the low demand on these they will consider, but I think for first few months it'll be as is

Some times I still dream. BTC to the moon!

philipma,
nobody forbids dreams.
Let's see why Bitmaintech concentrated forces on the creation of an intermediate solution . Why do they have lost so much time to create s5 + ?
Let's look back in the series of devices.
Let's examine what is more important: sale of devices or hashnest ? What is the future of hashnest when changing 25BTC - 12.5BTC . As for me, here we have answers to basic questions.

where you get these pictures ? I have not even arrive at my office today. I did not send you any further information to you ...

I recieved this information from PM

Upon looking again I see they are impersonating you.
My apologies ...

The antminer s5+ is real, the official china chinese bitmain website is selling it now. Just for 200 unit only. only for local.

http://shop.bitmain.cn/goods.php?id=47

The price has been drop from RMB 19000 to RMB 17200 / unit.

Im joining they private forum, this unit has given the low respond, because of the Noise 85dB!

It is extremely high noise level!
We have a new situation. Bitmaintech rapidly changing and sells s5 . We have a new deal to s5 . Only 352 USD ( 1.323 BTC) .
Hashnest also got a new s5 delivery .
It looks like the S5 will get a good deal on the market.

The USD352 is second hand unit from local China. I have very bad experience with second hand unit.
Before you buy, you must think the environment of this unit, mainly the china warehouse is full with dust and they running with water cooling systems, which will make the screw get rusty....

I did the math on the thermal design of this unit. I think it should be fine, and basically equivalent to an Antminer S5.

In our facility, the new S5s (with heatsinks on both sides of the board) have ASIC temperatures of about 42-50°C when using 20°C intake air. This means that the temperature difference between the ASIC silicon and the intake is about 25°C. Given that the power usage is about 10 W, this makes the thermal resistance to air about 2.5°C/W. The delta-T is about 5°C, which makes the back ASICs about 5°C hotter than the front.

This S5+ reduces the power per ASIC to 8 W. This means that the ASICs at the front of the machine should be about 20°C hotter than the intake air at the front, or 5°C cooler than the S5. The fan to power ratio for the S5+ is about half the S5s, making the delta-T about 10°C, or 5°C hotter than the S5. Add those two things together, and the rear ASICs should be pretty much the same temperature in the S5 as in the S5+.

If anyone wants to buy one or more of these, Toomim Bros can host them. http://toom.im. (I hope someone sends us one. I want to see how well they work.)

They did the right thing. If you want to put this amount of equipment on the market, the price must be lower.
The units may be dusty that is the fact but i have not heard about rusty screws or other components. This testifies to the high humidity in the mine.

yes,. they did the right thing. Maybe just im unlucly to get those unit. Photo as below

http://www.mms.net.my/bit/2250.JPG
http://www.mms.net.my/bit/2263.JPG
http://www.mms.net.my/bit/2264.JPG

Those must have been running even before the S5 was released! They have an S3 control board and not the latterday BBB ...... . I got my first S5 in the very first batch and it had a BBB!

WOW! And to think you paid more for this than anyone did for a brand new one must leave you feeling sick.

those are S3++ for second hand unit/. no luck at all. direct from china mainland bitmain.

I thought I was seeing things! Thanks for clearing that up .... How much did you pay for the S3++ from bitmain then (if you do not mind)?
To clean that up, get some surgical spirit (Methyl Salicylate) and a fine bristle paint brush ... and it'll be as good as new! I use that spirit because its very cheap from a pharmacy and works a treat even for removing thermal paste, but if you know of better and cheaper ....

 No evidence of rust, and no dust, on the pair of used S5s I got early this week.

 I'll also point out BitMain is giving a warrentte on these, think it's the SAME they were giving on new units.

 I DO wish they'd dropped the price a week sooner. 8-(

UPS in Canada lazed the f*** out last week and i'm supposed to receive mine today, any minute now. Good thing the warranty got extended to 30 days instead of the initial 15days, otherwise i would barely have any time to test it.

lol i just giggled a bit when I saw this...Id love to hear your logic on how this is "fake" when you were promoting the cloudthink.io scam and all they had was a horribly done "graphic" images of a fake miner.

and how did I promote cloudthink.io

my only post on that thread is here:

https://bitcointalk.org/index.php?topic=1141984.msg12045567#msg12045567


 it is an offer to review.   far from a promo.   So please be accurate.
---------------------------------------------------------------------------------------


and the op is asking 3299 usd for this  thread's item while it  now lists for 2750 on bitmaintech chinese site

So while the item has turned out to be real this seller wants far too much for it.

If you have trouble resolving this then let me know order details.

Did you start working for bitmain again??

No, but doesn't stop me chasing up a resolution.

I have send back all the unworking hashboard and control board to Mr Gao, but, long time no news no feedback from them. Im have not much hoping for that.

Hi All ,

Good news , Customers from USA , ITOP will ship locally , No tax and shipping cost issue .

Thanks!

What are the PSU's on the picture?  Are they the ones sold by Bitmain for the S4's?

We use several case psu and server psus ,try to get enough PCIE 6pin connectors, this is the pictures we do testing.
http://www.itop-corp.com/asset/file/image/20150811/20150811130436_11101.jpg

why do i smell ceramic hearing elements under heatsinks?

oh god so many psu..

This thing seems like a big pain the ass with needing what 18 pcie connectors?

You can use 2x IBM DPS-2000BB and J4bberwock BreakBorad where you have 12 pcie connectors per board

much more than that , 9x3+1(control board)=28  pcie 6pin connectors.
total 28 pcs

Wow, very efficient miner indeed :)

Can you prove your website is legitimate, your account is new.

Read the thread in its entirity ... the man has been made to jump through a thousand hoops already!

But 28 6pin PCI-E connectors for a single rig is mind boggling to say the least. Is the 6 pin PCI-E connector the highest rated power plug that exists?

it is 3400W per whole device, so 3400/3/3=377W per board. Two pci-e connectors per board is enough.

indeed it does and might be there first big mistake .  S5 + .


but it is real


https://www.btcgermany.de/bitcoin-mining-antminer-s5/

you have to translate that page my bad.



we should know this Friday for sure in the US I think bit main said this Friday for US sells

this sure does not work for a home miner....that is for sure.......3436 watts ...not at my 13c kwh in the usa

(then again winter is coming if you lived in a trailer with electric heat) :)

anyway at 13c kwh plus the say with shipping price of ..what was it 3300 bucks would be ugly ugly

only 2c kwh iceland or china farms would be interested in this (or not) imho :)

heh 321.61  usd electric cost at 13c kwh for 30 days (assuming you did not have to cool it) WOW!

I'll keep the two titan(s) I have running at 2500 watts thank you very much ......and let them be my "fair well off the stage" tribute to home miners next year

but I agree with other posts on here "they are not really even trying anymore' just a re-package and lame one at that

anyway my 2 satoshi's


for those who know ...would you be better off (or have to) use like 16awg Y cables like with the KNC Titans and Neptunes
just to be safe because of the plugs used (maybe?) not being up to snuff or is that a non-issue...just looks like would/could be a handy
addition ..it kinda screams "fire' from the pictures too me :)

but I don't know someone else with the expertise if 16awg Y cables for the PSU's would be prudent?

not to mention no home outlet will support 3400 watts.. so it would have to be specially wired in its own sub panel. and this thing looks like a fire hazard..

8 pin is rated at 150W officially, but for our use won't double whatever number each of us is comfortable with on 6 pin as it only adds 2 more ground wires.


No? You can power it from up to 9 PSUs if you want and split what circuits the PSUs are on as you like.

so i just run extension cords to different outlets? lol

seems that way if you don't have outlets that are close and run separate circuits. But it seems these are Beast Mode miners and more for rack mounted server farms..

Hash porn :)

I don't know, this thing kind of scares me. At this point I'd rather wait for the S7 which should hit soon enough.

If they were on different circuits, pretty much. I've got 2x 32A and 2x 20A circuits (all 240v) extension-ed into one room so I can test some pretty large things if required.

Did you mean the 3 modules ? yes , you can just connect each module and get around 2.5T hashrate ,
we may use incorrect PSU that make one board have xx , it gave us 7.1T at peak . see following screen shot .

Looks to be a number of xxx on the middle board of the middle unit. temp is showing cooler, but I guess that's because some chips are not hashing?

with this out the s-7 will be delayed into October at best.

I don't know, these aren't "new" so maybe this is the last hurrah for these chips.

Really not so different from the S3++ that got released in China, and the S5 was not that far behind it.  The S7 will be released as soon as it needs to be, so it likely has more to do with the competition's products than another one of their own. Anywhere from 1-3 months if I had to guess, depending on outside pressure.

I'd be willing to bet tapeout is either already finished or in progress as we speak for the new BM chip.

Peak means nothing, it is average that customers are concerned about and that screenshot doesn't give me any warm fuzzies about this product! And 6 fans at 4000rpm, how loud is this thing?

 It MIGHT ROI on 5 cent electric. There are places in the US you can get under 5c/KWH though not many.


 Way overkill, even running 2 connectors per hash board would be less than 200w / connector, most PCI-E cabling on power supplies is speced to handle at least 225.



 I'm sure you can use seperate outlets per power supply, 3x 1200W+ power supplies should handle this unit pretty easy. Just don't power one board from different power supplies, just like on any Antminer that needs that much power per board.

 It would appear the actual need is for *19* PCI-E, 2 per hash board and one on the controller (fan power). Not sure why they put the 3'd power connector on each board, not that it HURTS anything.



 I'm certain that the S7 already exists, and that BitMain is bulding them as fast as they can to replace their "farm"/Hashnet S5s they're selling off used - when they run low or out of S5s then they'll start selling the S7. I'm HOPING for end of August to mid-September but it's very up-in-the-air right now.

 I don't see this "S5+" unit having a noticeable delaying effect on the S7, it's just not efficient enough. Bitmain SHOULD have come out with it 6+ months ago and called it the S6 - THEN it would have had a good sized market. As of today, it's too little too late and too expen$ive.

Bitmain,

The simple truth is that you need to realise what your customers want.  We want something the same size and shape
as an S5 but more powerful, more efficient, and at a price advantage compared to a S5, kind of like going from S3 to S5.

Ideally, you would be able to take the new hash cards for this new machine and replace the failed cards in S5's as needed.

As for myself, I am not interested in the monster that is pictured above.

If you can't or won't give customers what we want, somebody else eventually will.

At the very least, break that thing up into middle and side units that can be bought separately.

Any chance that the hash boards for these things might work in an S5?

As we Engineers say...... Go Back to the Drawing Board!

I suspect this exactly what the Big customers have asked for. A very large Hash in a very small space. Yes the efficiency could be improved but at the expense of the Hash, and if you have very low priced electricity why would you want that...

unsafe as hell to but one way . lmao

What people are also forgetting is this is exactly what the big Chinese customers have asked for. The S5+ was not even intended for international markets.

Not to stir the pot, but how is it that PCIe connectors are only rated at 150W? That must be application-specific derived from GPU's. The connectors are based off the #5556 Molex Mini-Fit Jr connectors, which are rated for 7 or 8a (depending on type of pins used) per 12V+ circuit when used with 16 or 18awg wire (84-96W x 3 = 252-288W RATING): http://www.molex.com/pdm_docs/ps/PS-5556-001.pdf

Also in regards to temperature and current testing: 

I have purchased EVERY BITMAIN MINER since s3, s4, s5, s4+ - this one even with .05 power and NO diff increase (we know that's not going to happen)  It would take over 6 months to break even!  

I live in Vegas and that's a terrible gamble.

Rant over...

Boomin

They didnt did this for fun! Some big customer ask for it. Unfortunatly we are small here in US. (Canada)

I guess we will have to wait for S7 cause there is no other company that will deliver before.

I know lketc is looking to release on august 20 but until I see the miner we cant be sure.

Home mining is getting harder and harder!  :-\

What? You could run this whole thing from a single 240v socket....its 14amps at the voltage, would run comfortably even on the 20A circuit

And you could easily run a single PCI to each hashboard, if you have a server style PSU with breakout boards...its all about running the proper gauge wiring.

you can run this in one 2880 watt psu from finksy/j4woocky

just under clock it a bit.  maybe down to freq 275 or freq 262.5

 you would do around 2600 watts off  the 240 volt circuit  and hash at 5775 gh.


or you can have 3 different  120 volt plugs like I do in my garage . 

I have 5 circuits at 120 volts .

and I have  2 at 240 volts.

my question is how do I get it to be quiet .

I have to under clock it. to get it to be not be crazy loud.

I can power it safely.

I can do 10kwatts in my house safely.

The problems are sound and heat.

This is one goofy contraption.  why the obsession with PCI connectors?  Is that really the best solution for industrial scale mining? 

If it is true that lktec is releasing their new rig on or about August 20th, then you can bet top dollar the S:Next-One from bitmain will be on the scene sooner than you can bat an eyelid! Keep your eyes peeled.

I prefer it greatly over a proprietary power supply. High end efficient used +12V server power supplies will beat new every time, not only in price but performance as well.

Buy yourself an automatic wire cutter/stripper machine, some 5000ft spools of 16awg primary wire, reels of crimping pins and bags of end connectors. And you will never have to buy a PCI-E cable again, and you can make them just the length you need.

thats all good for smaller scale home hobby miners.. but you gotta think giant farms would prefer all in one units similar to the s4+, SP10 and SP3x.. just makes the server rooms cleaner and easier to swap things in and out.. but then again ive seen some china farms that simply dont give a crap about cable management and are just giant rats nest of wires everywhere.

Nope, 6 pin PCI-E connectors have certainly run their usefulness, both economically and practically. They should have reverted to the trusty old screw terminals that were sported on the S1.

not sure that would be very good for my 2 MW facility.  that is a shit ton of work! 

When you look carefully at the PCIe power connector spec, one of the +12V lines was allowed to be NC (Not Connected). If it was connected, it was required to be +12V. Hence to be absolutely safe, you can really only count two of the +12V pins as delivering power. Hence a more conservative estimate would be much closer to the 150W value for long term use (i.e. not the absolute maximum). They probably didn't want the connectors to discolor over time due to the heat.

Yes, I know that most all miner vendors assume you can get well over 200W per connector. Not everybody buys a power supply where the PSU manufacturer has connected all three +12V lines with 16AWG wire.

PCI-E specs the 6 pin version at 75 watts because they are being VERY VERY conservative. It was the 8 pin version (2 extra ground leads, NO extra +12 leads, DUMB choice IMO) that specs 150 watts.

 These are PCI-E specs, NOT connector specs.

 Power supplies with PCI-E connectors are a LOT more common, I see no point in reverting to primitive screw-type terminals and many reasons NOT to do so in the wattage range these miners run.


 P.S. - worked at Qualidyne for a while, where 100 amps was a LOW current output on many of the PS I tested for use in mainframes, commonly at +5v. This was a long time back though, you needed most of a square foot to fit a 1KW power supply into back then, switchers had a lot lower frequency capability due to the parts being many many generations older tech....



 One plus side (for me) on using standard ATX power supplies - eventually the living ones can get switched into real computers, if Bitcoin mining ever becomes completely uneconomical and I get to switch back to working on my d.net/GIMPS/Folding@Home planned farm....




 Not a real good idea, but if you use the heavy-duty A/C type cords it would work. I prefer to just wire additional outlets close to the mining area(s).

I priced it out and with my 1 MW facility it would have added at least 100K USD to the overall build out cost. I'm willing to do a lot of work to get that. Most of that would be in the overpriced power supplies that are bundled with the miner making the overall cost per ghs that much more. Saves money ongoing because I can guarantee you my server power supplies are more efficient than say the ones in a S4. 1-2% savings of 1 MW let alone 2 MW will add up quick.

The key is the automatic wire cutter stripper machine: https://www.youtube.com/watch?v=3vb0RM1xMCw

I liked the screw terminals of the S1 but the plug and plug of pcie on both ends using the breakout boards allows for easier swapping of equipment. Which, when mining on an industrial level that is pretty much an ongoing task.

Older pic showing clean pcie install: https://i.imgur.com/E6Ju4Us.jpg

EDIT:

https://i.imgur.com/mi2T3Tt.jpg

Also don't forget the modularity it has in that it allows us an upgrade path to new hardware without having to buy the power supplies all over again.

QuintLeo-  All the more reason for people to be getting away from ATX power supplies.  They are over-priced, and under-built.  I think it's past time everyone stops pretending they'll ever re-purpose 20x ATX PSUs for anything, lol.


Very nice farm, and excellent choice of PSU.  There is no better, in my extremely biased opinion.

looks cool but i doubt its real

I believe your farm is using 220v AC. So please try our APW3 power supply. If you want to build some large hash power, please talk to us in advance, and we can ship the PSU by sea, which will be very very cheap right now. It has 1600w capacity and it is very good for the S5+ deploy.

https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

We are preparing the oversea sale of the S5+. Right now we are very sure on Friday we can open the sale officially, if nothing unexpected happen.

Here we go... Drumroll.   :-)

The biggest  APW3-12-1600-B2 manufacturing mistake is too short PCI-E cables.

The problem is, even the two side by side placed S5 Miner, not to mention S5  +

What an absolute clusterfuck!!

Historically, odd numbers are new chips with Bitmain. So it's safe to assume that this is indeed the "last hurrah". S7 will be a new chip.

You're an idiot.😜

For medium amount of cables (lets say 1500+ cables), I agree that the automatic wire cutter and a semi automatic wire crimper are probably the way to go if you have someone or some time to operate them.

For even better efficiency, and for more than 5000 cables, I'd probably suggest to go for the fully automatic cutting/crimping machine:
https://www.youtube.com/watch?v=XUzsm2FQteA

The cost is roughly $6k for the automatic machine.
Semi automatic crimper + automatic wire cutter/stripper will cost $2k to $3k depending on options and brand.

Of course, it takes a lot of time for the assembly of the cables.
So, as I said from the beginning, it's only a good option if you have the time or someone to make the cables.
If you don't, buying the cables and server PSUs + breakout boards is the most economical option.

There are pros and cons to use server PSU ,  like 2800W , you buy from china , it is 6KG each, it will be expensive shipping cost .
http://www.itop-corp.com/asset/file/image/20150812/20150812211924_53091.jpg

I think the IBM 2880W is a good option since 3 of these PSU's can run 2 of these miners.  3 PSU for every 2 miners is not bad.

That automatic wire cutter stripper crimper machine is just too badass I want it. Looks like it takes a bit of setup to get it running. Thanks for the link!

I prefer the 2880w power supply mainly because it is modular with the breakout board, and that allows me to select the awg of wire to use for the pci-e cabling, the length, and reuse it in case of a dead supply.  It is extremely efficient compared to almost every other power supply, does not get very hot, and has 3 fans to cool so if one dies it wont. Add in the fact they are available in the states in bulk shipped for less than the cost of the breakout board.

I think just one of these 2880w power supplies could power one s5+, even at standard clock. Right now my farm is powering 5 S5 per 2880w power supply and my metered pdus are reporting about 3300w being consumed. I may order one up just to test.

This is what a 6 2880w / 30 S5 readout looks like on one of my pdus: https://i.imgur.com/JTw7HZ0.jpg

Hi all,

Just a quick update to let you know we've just uploaded a quick preview of the miner!

https://www.youtube.com/watch?v=6o3QLdlxbLo

Tutorial coming soon...

Enjoy!

where are my breakout boards on your PSUs ?  ;)

Care to share clock speed and voltages ?

432 chips = 7.2 times of antminer s5. With only 7.7THS that means it is underclock right ? I think there s many overclock rooms, maybe for 9THS with 4500W

Thanks..

The amount of heat would be crazy, that would be 3 * 24/7 Oven of heat crammed in a tiny bundle :S.
I look forward to specs but laws of physics apply to mining gear too.

Its not that bad, a little over 15,000 BTU/hr.  If you wanted to air condition it a small 1.5 Ton window unit could handle it.  Otherwise just dump the heat to outside.

There isn't too much headroom on the S5 and S4+/S5+ (also due to heat) because of the fixed voltage.

I saw a gui for this s-5++ and this unit was at freq 325  which is lower then the s-5's   freq 350


now  can you bump this to  freq 350  and push 8200gh  ?

I have no idea.

Hi all,
As you can see the below screenshot , there are 6 x 120mm cooling fans with 4000RPM above , it is really nosie,I am thinking the possible way to make it cooled by water cooling , any ideas ?

http://www.itop-corp.com/asset/file/image/20150811/20150811205427_82838.jpg

Oh my god, this is as loud as 10 S5 if its the same fan.

I think water cooling would be challenging to say the least, i don't know if there's heatsinks that would fit and you would need to deassemble it and have the heatsinks fit just right in between the boards. There is so much heat, maybe some silent but higher cfm/pressure fan would be better.

Same noise as an S4+ at a decent ambient or a HashCoins Ares so its to be expected. It should be possible to watercool although you'll still need some fans to move air over the boards (and backsides).

Well with default clock and 432 chips it should be 8316 ghs right ? Or it already too hot just go by default clock ?

Since every rooms on my farm has 5500 watt caps, I wish I can get atleast near 5000 watt system. Like that S5+ OC to 4000-4500 watt and around 400 watt more for 1/2 PK AC. It doesnt matter if it goes to 0.6-.065 watt/GHS as long its under 0.7

We did not find the breakout boards for 2880 PSU on your store, does this board also transfer the AC socket onto the board or not ? Could you show me please , we may purchase some for our customers in future .

Below are pics of his board. Yes it transfers AC through the board as well.

https://i.imgur.com/yqJjKXo.jpg?1

Yes , this really helps , if I use it for S5+ and connect 14PCIE 6pins of them, which ones I should connect , or just choose any 14 of them  . thanks

Does not mater on this board they are all the same.

I am really wonder why BITMAIN have no statement about this new rig yet, They are totally silent about this thing they are not accepting nor denying.

Could be that you just didn't read the thread;

James,

the PCIe connectors are all soldered to a common 12V, so any one is fine.  I have run the cables/connectors up to and over 300W each with single-cable powered Neptune modules without a problem. Contact J4bberwock directly and he can quote you for a bulk order, if you are in North America and are looking for a small quantity to sample PM me.

As I mentioned before though, I would be hesitant to run a full S5+ off a single 2880W PSU for long term as it is over 3100W DC draw. However 3x PSU's for 2x S5+ would work well IMO and still give you better efficiency from the PSU's.

Thanks for the clarification, i didn't read this before, i haven't seen anything or any news about Antminer s5+ even on Bitmain chiness website,but it's already Friday today so let's see what result do we get.

I don't understand how if you worry about a single PSU and a single S5+, why THREE S5+ and TWO PSU's would be OK. Did you get things a little reversed here? Maybe you meant 3xPSU and 2xS5+?

I'm sure that's what he meant.

Now is the early morning at 8:00am , they don't start to work yet maybe .

hi itop, can you upload video about that miner, so i can hear how loud that 6x bad*ss fan singing..

wonder if this one is real

In the U.S. This is a more common style 110v or 220v so do these breakout boards get made for USA different from say Europe?
https://i.imgur.com/rT1znrz.jpg?1

 


yeah he did as 3 x 2880 = 8640 watts    and 2 x 3446 = 6892 watts

and you could have   the  extra power to try freq 350 if you have cooling

Yes , you can watch the video at youtube here
http://www.itop-corp.com/asset/file/image/20150814/20150814103047_22202.jpg (https://youtu.be/jGK2ZGuFZWI)

oh thanks..
sounds like saw machine  ;D

Yes thank you, reversed my numbers accidentally.  Edited

They only come in the one configuration.  The C13-C14 connector/receptacle like you posted is only rated for 10A max.  The C19-C20 is not less common, but used in different server/enterprise applications, and is rated for 16A.  (2880W / 240V = 12A, I've measured it as high as 13.5A at the plug)

http://www.ebay.com/itm/AC-power-cord-C20-to-C19-12-AWG-4ft-White-Lifetime-Warranty-/311422141814?


the cable above and a 240 volt pdu like this



http://www.ebay.com/itm/Dell-AP6031-New-Open-Box-PDU-90-DAY-WARRANTY/291411660176?


you can do 2 of the 2880 watt psu's

Well,Finally the wait is over, Bitmain have just officially lunched at their official website, i have checked it's final prise with tax and within china local shipping it's about

10.512 BTC
( 2778.75 USD ) each unite.


Which means it's almost $420 per s5 unit equal. As it's hashing power is about 6.6 s5 units equal and so it's final price is about $420 each s5 equal.

i think it price should be under $1800 as with final checkout would have even cost upto $2100 plus with tax with local within china shipping. (My personal suggestion)

It's quite expensive at the moment.

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

bigger is better?

Not sure how bigger applies to this miner and how it is better.

It's like saying less space is better.

I think it's not quite bigger,it's seems even a bit smaller then 3 of s5 size with less power consumption as well,but the problem is it's price right now,it's quite high.

I understand this miner serves a few purposes..

It makes the biggest single "Real" miner on the market.

It helps bitmain get rid of excess old stock.

& it creates a single miner out of 6 or 7 miners making it easy for people to manage in a server environment...

------------------------------------------------------------------------------------------------------------------------------

Thats fine & dandy for some but for the home miner this sux balls unless another miner is around the cnr....

Hey Bitmain...

Why not create a miner like this

Make it (Top Speed Locked @ 3500gh @ no more than ur power supply - 1600w)

This would give u the best gh per watt miner on the market & Be available for everyone to use (Maybe the 240v option only???)

It would kill the S4+ by 1000gh making the upgrade path for most a non issue & Keep the miner to one psu, one plug.

Edit : Just because someone else (Maybe Phil) mentioned this before,

Sell it like this but with the full controller, Then u'll have an avenue to sell another one like this later as an upgrade for 4.5 btc

Looking at ur current pricing & going off ur past pricing, With current market rates.

Sell the miner @ 5 btc plus postage...

This will keep it off most of the worlds customs & taxation rader making it a doable thing...

The S5+ is too big (Power wise) & too pricey (It will get picked up by customs & taxation) for most normal miners...

There's one thing i can assure u off thou if u have excess stock to move, The home miner market is sitting on a cliff at the moment waiting for a product to move it in the right direction..

With my above spec's, U would clear house! 

Edit : Cause someone mentioned this before (Maybe Phil)

Sell the first one with the full controller, This will give u the avenue to sell a second one later at 4.5 btc providing an easy user upgrade.

This option makes u another 0.5 btc plus delivery & saves u cost on a second controller.. (Whatever thats worth)

well 2375 plus 98 to ship to New Jersey   so 2473 total   direct from bitmaintech


or 3299 plus 76 to ship to NEW JERSEY  from here.

so 2473 bitmaintech  vs 3375 itop     only a 902 usd markup ::)

now at 2473 

10 cent power 2% diff you have a profit after 422 days
 9 cent power  2% diff you have a profit after 325 days
 8 cent power  2% diff you have a profit after 284 days
 7 cent power  2% diff  you have a profit after 244 days
 6 cent power  2% diff you have a profit after  220 days

ITOP hasn't marked it up that much. 2696$$ US priced from bitmain in China.

And I did receive s5+ today from ITOP-CORP
I'm at work here on the east coast but cannot wait to start playing around with this bad boy later. :)

show me a link for 2696

I can not find it just 3299 and it is 76 to ship

 Don't forget the block reward halving in July next year - looks like near the end of the month right now, but I'd bet it'll keep moving up - still likely sometime in July though.

 Don't forget to add in cost of power supplies too.



 https://www.bitmaintech.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B
 $2375 plus shipping.

 
 Seems like BitMain is out of used S5s - or more likely since this is the 14'th they're setting up for a "21 August" batch and just haven't completed the website update for that.
 They also have the price listed a few bucks lower, probably due to Bitcoin price drifting down some the last few days - $348 vs $352 yesterday.

I have more then enough psu's   to run one of these


So for me I do not need to think psu.

Use Bitmain 1600 Watt PSUs with S5+.It seems to me a cheap and reliable solution.The real decision is will there be S7 and when will they release it?

2600 USD for S5+?250 day of ROI.Well, I expect the price will be below 2000 USD including transport.

Don't be in a rush to order, the website currently says Sold Out.

Maybe they priced it too low.....  :)

Or they made too few.......

Thank you Phillip. I also have C19-C20 cables (closer to 7' long) and PDU's that can accommodate 3-4 PSU's in my thread (found in my sig), along with boards, cables and PSU's. Plus, with the $CAD being quite low right now, it is reducing the actual cost of shipping for US customers significantly, and is quite affordable.

 S5+ wasn't sold out very long, if at all.
 S5 used batch 7 are still showing sold out right now though.

They changed the shipping date portion again so i'd be surprised if they dont do a 3rd batch of used units soon.

Looking at the pics/specs its obvious they can make an S5 sized unit with this hardware. The specs for that would be 2.6TH@1150 watts for about 800 USD.

I hope they go this route as that would be a way more manageable home miner.

It's not about home miner problem ... The real fact here's that very soon in upcoming January the blockchain is gonna turn half and so 7.7 Th would be almost equal to 3.3 Th means it would requires the double of the current hash power while more increase in difficulty but also expecting the rate to get high as well.

It should push value up a bit. Probably, but yes i think its going to push off some miners. So it should be also followed with a big diff drop. I believe it may be ROI-able depending on how strong the true next gen/wave will be.

try june not jan  and in the world of btc 5 or 6 months is huge.

I beg your pardon, You have just said it's going to half the blockchain in JUNE 2016 instead of JAN 2016 ?

yes am I mistaken?

 you said 2016 Jan

I said 2016 JUN

Wiki has 2016 Nov


 my source is wiki  and they estimate Nov 2016

https://en.wikipedia.org/wiki/Bitcoin

User(s)   Worldwide
Supply growth   25 bitcoins per block (approximately every ten minutes) until mid 2016,[2] and then afterwards 12.5 bitcoins per block for 4 years until next halving. This halving continues until 2110-2140 when 21 million bitcoins have been issued.

No probably i might be wrong as i have read somewhere that blockchain is going to get half in upcoming January 2016,but might be you are right and i wish that would be true so we have about 9 months to get RIO,which i can absolutely as electricity cost here at my place is 0.08.

well, July-ish - but subject to network hash rate changes: http://bitcoinclock.com/

Yeah

June - Me
July -  http://bitcoinclock.com/
Nov -  Wiki


Are all better then Jan.

Jan would be a problem as it is not far away. (under 5 months)

I think 1 year is plenty problematic :)  Could you point to the wiki page that claims November?  That needs fixing.

That's quite helpful now, i got it. Thanks mate for sharing.

I am a bit confused here... Please correct me if i am wrong or explain to me if i am totally wrong.

I heard that there are total 21000000 BLOCK's for BTC for the Entire BTC Network or Life when this 21000000 Blocks will be discovered then there would be no more Blocks, But what i can now see in this website that BLOCKS COUNT 369889 and bellow it's showing...

Hour Hand   Minute Hand   Second Hand
Blocks per Revolution     210,000   2016   144

Which means that 210,000 Blocks is only meant to be in the 4 years Cycle ? So there would be about 210000 Blocks in each cycle or there's something else ?

The reward will keep halving so getting the "total/max" isint going to happen in our lifetime, so feel free to not worry about it. Everything else is so far in the future BTC is not in any danger of terminality. When we get there we can do whatever.

The 21m isint how many blocks its maximum BTC supply.

Ahhh ok i hope it will keep going for long enough, Actually i am just moving ahead with 200 TH small mining firm soon,almost at the final stages of the setup,so hope for the best.

Upcoming januari- it is a chronology of the Mayan ?

Reward-Drop ETA: 2016-07-27 16:38:45 UTC (49 weeks, 4 days, 23 hours, 50 minutes)

Yeah i never heard Jan 2016 either from any logical source. Sound like someone meant to say Jun and he typoed or misread to Jan. In a nutshell we have about a year. A little less. That clock seem very accurate, although it will probably get knocked ahead bit by bit to a slightly earlier date.

 Yeah the clocks says July, but It could shift to June(my guess)   if diff has steady +2 % or even August if diff has steady -2%

 July 2016, actually - late in July by current estimate, but with hashrate almost constantly increasing that date estimate keep creeping forward a little. I'd guess the actual halving will be mid-July 2016.

 ROI on this unit before that point depends mostly on your electric cost, and somewhat on the rate of difficulty increase. I believe, based on my estimate, that a S5+ will still be profitable after the halving - but only BARELY and not for all that long afterwards.


 I suspect that the wiki page hasn't been updated in a while, if it's still estimating November - but I think June is a bit pessimistic. Possible if difficulty explodes at some point due to rapid adoption of next-gen miners and the current stuff doesn't get shut down very fast, but I don't think that's REAL likely.



 The S5 is back in stock now, with a "shipped within 10 days" note. Guess they're getting a bit more "flexable" about their batching as their inventory goes down on their farm....

How difficulty adjustment works:

Every 2016 blocks, the Network adjusts the current difficulty to estimated difficulty in an attempt to keep the block generation time at 10 minutes or 600 seconds.

Thus the Network re-targets the difficulty at a total difficulty time of:  2016 blocks * 10 minutes per block = 20160 minutes / 60 minutes = 336 hours / 24 hours = 14 days. 

When the Network hashrate is increasing; a difficulty ( 2016 blocks ) should take less than 14 days.  How much less can be estimated by comparing the % Network hashrate growth + what the Network hashrate was at the beginning of the difficulty ( 2016 blocks ) against what the Network hashrate was at the beginning of the difficulty ( 2016 blocks ).  This is only an estimate because you cannot account for "luck"; but you can calculate reasonably well using explicitly delimited stochastic ranges.

The easy way to think about this is to look at this graph and see how close to 0 the current data points are on its y axis.  If the blue line is above 0 the difficulty ( 2016 ) blocks should take less than 14 days; if it is below it should take more. It hasn't been below 0 in a very long time.

Here is a short video of Unboxing S5+ from ITOP-corp
 

https://www.youtube.com/watch?v=itpcni266aA
Quick video setting up the S5+

Here's the first run but one board failed due to paper clip jumper on PSU

https://www.youtube.com/watch?v=mnjPqqQxZWI

I've got a couple more videos uploading on you tube if anyone wants to see a bit more about this.
It really is quite nice. The total weight seems to be the same as 2 S3's
It seems built sturdy the sound was t nearly as bad as expected. Up close about 90db and 2 feet away 75db
I anticipate a much louder operation running the 2880 IBM PSU's but this was tested with corsair 750 Gold @ each blade. @353W/blade X9 plus fans and control board. Running factory clock settings
I will get as much info out as I can as soon as I can.

nice what is the real performance in the pool?

if someone manages to find a push=>pull solution for more quiet fans i think i will by one of this babies...if not, i'll just wait for the s7.

we are seeing 7.7- 8.0 TH at stock settings

Damn those fans are going flat out, and seemingly without reason. If you're at 25C ambient, then even at a 40C ambient those chips would be at 60C = still far below the cutoff. May be able to get away with removing / unplugging the front 3 fans, especially at that ambient.

We are going to see what happens ;) will post results soon.

https://i.imgur.com/mXBfafU.jpg?1


You can see we changed the freq up a bit

We removed front fan power and
Noise level was the same, chips immediately rose to 70C back fans spun to 4700rpm we aborted test.

A humble request to upload some better quality video's instead of the one you have uploaded,we really can't see anything proper in your videos,that's quite disappointing.

I will have better quality videos posted soon.
Sorry those were quick videos from my iPhone

 I wonder why Fan 2 is higher than the others? A few RPM sure, but 240ish seems like something is partly blocking it, different model from the rest FNAR, or something wierd going on?


 Are the front fans push or pull? If they're push, would make more sense to try unplugging the rear fans and see how that affects cooling IMO.

https://youtu.be/pu6qtsuw8-4

I hope this is a bit better quality.
I will post more tests and vids soon.

This is fairly reasonable for homemade ghetto videos :) She is loud as fuck xD

If i ever get one somehow i'll have to replace absolutely all the fans.

It is easy to change the frequency , thank you very much for your quick action to post the testing results as soon as your getting product from ITOP Corp (http://www.itop-corp.com)

under configuration click advance settings. That brings up frequency values.
From there it's easy to change settings.

Thanks again itop :) that was very fast shipment. And thanks for the poster.

Hmm... I want one....

I too what one..but I also want a high maintenance 'gold digger' hot girlfriend I can't afford too ..neither one ROI's worth a damn ...but I'm not so far
gone as a nerd yet I'd get this miner ....not that I really have a shot at the hight mantence girlfriend either..but hey I only chase 'practical' type
'impossibilities"  (see Mom there is still hope!) :)

then again somewhere down the line...at a future time... may find a used abused discarded asic unit above (or girlfriend) that I may still find attractive
and take home like a lost cat..so there is hope :)



 

IBM 2880 H PSU's came in today, so I'll get that put together soon for a bit more testing.

Some excitement is going on because of the newcomer)) also want one for start  ;)

Friday's orders should start dropping in the US on Wednesday.
I am going to take a vacation day if I can work it out with all the items on my schedule for this week.
I have other personal appointments for Wednesday morning and Bitmain is requiring a signature so I may as well be here :)

Why would I buy from Itop, when Bitmain is selling them direct for $1000.00 cheaper? And even @ Bitmain price of $2307 + $75 shipping to USA...

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

It would take 122 days to ROI WITHOUT POWER COSTS NOR DIFFICULTY INCREASE. Add in power costs (approx 1/2 of daily earnings) and difficulty, This device WILL NEVER ROI.

Run away! You are throwing good money after bad on this folks.

You would Totally ROI on free electricity, why do you FUD so? :P

I'll just stick to S5 however.

The bigger thing I think besides paying more is the warranty. They have not answered my question how someone who is not a official seller can promise same warranty as manufacture - https://bitcointalk.org/index.php?topic=1152746.msg12169075#msg12169075

Maybe they have bought enough miners just for parts and replace dead miners?

They should say they provide a similar warranty not same as manufacture then.   Are they paying for components from Bitmain? Are they acting like they did not resell and try to use bitmain warranty even though they are not official reseller and have transferred to another person ending the official warranty?

We know Bitmain has a stock of all components.  I just wish Itop would say they provide similar not same.   And I could be crazy maybe it's just me thinking they should specify not official reseller and similar not same warranty.  Maybe if Itop would post their warranty TOS I would feel better about it.

Who knows maybe just bugs me.

Well he says they charge more to offer better customer services. So he says the same warranty is held by them by holding extra funds to replace damaged stuff. I don't know how they can be sure they wont run out of stock however...

Like the controller there is one per unit.  I just don't see them having a ton of extra unit's.  But I could be wrong.

And like bitmain warranty service there is a ticket system, phone number, email, US team, China Team.   I just don't see how Itop can say they have same as that level.  And to say they have better service then a almost 24 hour system.  

They can offer different... but same seems to push to sound like official reseller and they are not.  Again I could be crazy.  I just think they need to list their  TOS for warranty and make it clear they are not official and not the same warranty.

Looks like batch one of the S5+ might be officially sold out, i know day one it was greyed out but it came back up a couple hours later.

Also looks like the used S5 batch might be sold out, it has been greyed out since early this morning.

yeah and do you think that 1k justifies this "better" customer service and local warranty? i dont think it really does.. to each their own though, im sure itop has sold plenty

I am still trying to get them to say like warranty not same as - https://bitcointalk.org/index.php?topic=1152746.msg12177661#msg12177661 they seem slow on request.... so I really don't see the better customer service.

Were talking a small company.  They have not shown more then 1 miner in a picture so we don't know stock, or parts they have.   

I think them saying "better" customer service is something hard to gauge. And as I said before how does a small company beat "And like bitmain warranty service there is a ticket system, phone number, email, US team, China Team.   I just don't see how Itop can say they have same as that level.  And to say they have better service then a almost 24 hour system. "

I don't see it happening but again I could be wrong.

I have had no issues. I ca only count for me but 5 stars
service

The bigger problem here is the price right now. :/
BTC Fork ?!

 got down to 200 on coinbase  back up to 230

my guess is bitmaintech converted all of its s-5+ sales to hard cash.

They had more the 200,000 usd in s-5+ sales

cashing out fast like that? Or this?
http://www.bbc.co.uk/news/technology-33974826

 They tend to grey out stuff while they're adjusting their posted "bitcoin price =".

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

After they launched New chip BM1385 Chip ( 230W / T) , I think people prefer to wait for the S7 that based on this new chip .

How did mining hardware thread end up here???
It took a bit of searching to find it. One of the Mods make a goof?

One technical question I have:

- What i know/heard is that when you have one dead chip in S5 device the whole blade will stop working, where this is not the same on S3 devices.

Is this true and does it mean that because of bad cooling (let's image) you kill one chip from the blade the whole blade would stop working and you have 1/2 of S5?

Please someone confirm this.

Best regards,

The first post is ITOP selling the machine so I think this is the right place. Bitmain have their own official thread for discussions of their machine.

https://bitcointalk.org/index.php?topic=1152746.0

I do not believe it. Bitmain wallet
1KwA4fS4uVuCNjCtMivE7m5ATbv93UZg8V

It just blows my mind how little people on this forum understand supply and demand. Yes bitmain is selling them for a lower price. Sorry bitmain doesn't have any for you to buy. So no you are not buying anything from bitmain at a lower price. They have been out of stock since the listing was made... So their price is pretty irrelevant now isn't it?

Both are still greyed out and states sold out.

I received the wires for the 2880 PSU's
Thanks ITOP for those. This miner is running smooth and cool.
Next I will get this running on the 2880's :)

I agree I get people sending me offers for less then what bitmain sold them for and there sold out I am like hmm how do you come up with that number if I have it and no one else does then obviously the price on the website is irrelevant because I have one to sell in hand and he doesn't right? or they say something better is coming so I say go ahead and wait and see how long that will be

It just boggles the mind that this stuff sold out at these btc prices to mine.....from what I can tell better deals on ebay and ebay is
frigging high to boot!.....(the ways of crypto are mysterious to me!) :)

I was having a bit of trouble finding a pin-out for the 2880 server PSU jumper switch and AC pug wiring. Anyone?

A LOT of times companies padd their sales stats... Just sayin'..  ;)

So far I found this to set up the 2880 PSU
