Topic: ANTMINER S5+ is available to order, 7.722TH/S 0.445J/GH - page 18. (Read 40238 times)

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

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.

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.

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

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

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.

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://bitcointalksearch.org/topic/all-sold-1100w-platinum-94-server-psusbreakout-boards-wcables-1037372

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?

 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).

B1 sold out!

Edit: Not anymore it seems

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%.

It is not cloud mining contract.
This is a BTC loan with very small percentage .

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

­> 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.

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

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.

Looks like they still have some in stock.

I see 8.9BTC not 6.6BTC. 

about to order one of these beauties

edit : just noticed they are sold out of batch 1

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?

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...
