ANTMINER S5+ is available to order, 7.722TH/S 0.445J/GH

[zagamon]

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

Or just two of these 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

Do not connect more than one PSU to the same hashing board!

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

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.

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

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.

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.

AntMiner S5+ Batch 1

SOLD OUT

[QuintLeo]

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

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

Do not connect more than one PSU to the same hashing board!

 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.)

Customers must buy the set of three modules as one unit; Bitmain is not selling the individual modules of the S5+.

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

the so called best ever cgminer never neither increased my earnings nor reduced my electric costs over the bitmain fork

 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.

AntMiner S5+ Batch 1

SOLD OUT

That was either fast or a great marketing strategy.

AntMiner S5+ Batch 1

SOLD OUT

That was either fast or a great marketing strategy.

Or they only had 20 in stock.

[lovenlifelarge]

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

[flikflak]

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

[SFMiner]

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?

[markj113]

about to order one of these beauties

edit : just noticed they are sold out of batch 1

[Darthswan]

I see 8.9BTC not 6.6BTC. 

[zagamon]

Looks like they still have some in stock.

[sloopy]

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.
