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

Can this be rack mounted?  Does anyone know?  Looks like brackets on the front sides but they seem funky
Please folks -- ears on rack mount chassis are NOT the only thing you use to mount them! Or better not be.
All heavy rack mount gear is supposed to be sitting on a support shelf/brackets. The ears are mainly only to keep them in position.

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

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

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

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

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

this spec is for upcoming S7? probably...

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.

Wow! Thanks for the great info. Very helpful.

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

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

I don't think you can use only 2x PSUs. According to bitmain's product info
Quote
Do not connect more than one PSU to the same hashing board!

You can use as many PSUs as you want as long as you don't have multiple PSUs powering the same individual board (of which there is 9).

Do all PCI ports need to be powered?  Or will it run with 2 on each board?

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

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

But now I'm just getting out of stock.

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?



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.

B1 sold out!

Edit: Not anymore it seems Smiley

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.

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


 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.

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.

Spondoolies haven't even given us a peep that they will sell to us

Quote
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.

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.

I am slightly concerned about the efficiency of next-gen miners popping out at .3 by the end of September

Quote
From what I'm seeing in announcements, I'd guess the ONLY miner at under .3 that will show up before December for non-major-farms will be the S7 - and when that actually goes on sale is very much up in the air.
 I don't think the Lketc will actually be available on August 20, I'd guess that date is when they plan to announce full specs and preorder.

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.

I'd love to see if you could under-volt this, to allow it to run on 2 X 15A breakers.


 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).

Bitmain can offer a scaled-down version


 They've already said that they have no intention of doing so on the "sale" website page, it's buried somewhere sorta-near the middle in the specs fine print stuff.
