Space savings is nice, but the efficiency doesn't justify the way-too-high pricing. Most folks are POWER limited, not space limited - the efficiency gain even THERE is minimal.
Price needs to come down to make this unit worth even looking at - if your electric is cheap enough for it to even have a PRAYER of ROI before the bitcoin halfing next summer, you can ROI even faster with standard S5s (while they are still available).
Also, looking closer at the pictures, it looks more like 2 PCI-E per hash board, not 3. Specs indicate 2 connectors would run one hash board with reasonable safety, even if the heat issues aren't as bad as I think they are and you CAN overclock these some.
Re center: perhaps having sides helps with cooling and center unit alone would be overheating at full speed.
That doesn't look likely at all, with the layout of the boards in each part of the unit.
Apart from saving on a controller, what is the the advantage of having 3 combined units?
Save 2 controllers, actually, per trio - but that's a very minimal gain vs. the flexability and other advantages of having single units.

The price is uneconomical at $3061 (plus $90 shipment, I assume) for 7.7 TH at 3400w- checked at minimal increase of 1.57% and 10c-it gives more than 360 days.

Its the hashrate of nearly 7 S5s in the same package as 3 S5s, with better directed cooling. Its beneficial for people wanting to run high density setups with some form of heat exhaust. Re center: perhaps having sides helps with cooling and center unit alone would be overheating at full speed.

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.
come on bitmain sell them like this!!!!!!!
solves a shit ton of issues.
and if I am right the center would do 2550 gh at 1134 watts the lower cost would allow it to come into the usa with zero repeat zero duty issues.
I would be willing to do a long series of tests for you if you sell me a center piece with the controller. At a decent price.
I guess 900 is low but you would get a long write up showing how to run it .
What a nice way for home miners to get back into mining sell us the center piece with an add-on option for later!!!
This pricing avoids all usa duty issues since the center piece would be well under 2500 usd price.

Where did you get this idea that shipping above 2500 will have duty problems?
My last order was 2 S4+ and 4 S5, that was about 4000 dollars order. and got right to my place in 2 bussinnes days in FL shipped from bitmaintech.
More then one of us has had duty issues over the 2500 price mark. Fedex did this with a few buyers. DHL also did it.
I ordered all my bitmaintech gear using ups to ship. I also always order in the 1000 dollar range. Just to avoid issues.
Yes i also use UPS, i hate the idea that S5s are still cheaper than to get this new monster.

S5 are still available at http://www.bitmaintech.com
Is it too late to buy an S5? Did they announce when will S6's be send?

Fool, let me point out the blatantly obvious what you clearly have completely missed ...
Bitmain supplies S3,S3+,S5,S5+ miners, that do NOT come with PCI-e cables.
Your statement is quite clearly that any PCI-e cable is OK to run over spec.
Try engaging your brain before typing.

That's some pretty strong punch. I will keep this one on my wall as it made me exclaim myself in real life.
I don't have anything to say for or against but still between the lines of punch and kicks there's some good information there.
I'll have to check those dual 6pin cable...
August 09, 2015, 05:09:26 PM
The PCI-e cables themselves have a specification that they are expected to work within.
Some manufacturers may build cables closer to those limits than other manufacturers, but they are still within the specifications.
If you're defaulting to the "you only run 75W because the specification says so", then good for you. The rest of us will continue doing what we've been doing for years.Some manufacturers may build cables closer to those limits than other manufacturers, but they are still within the specifications.
I feel like you're arbitrarily deciding what will work or not. I've actively tried these things and I've actively measured cable temps so it doesn't really make sense for you to say its all about to explode.
Your the one who is "arbitrarily deciding"You have someone somewhere telling you what to say is OK. Keep being a good little doggie and doing as you are told. Ignore specifications, they're only for he faint of heart who think failures and fires matter
I haven't worked with Bitmain in months, who is "telling me what to say" now, what will you default to next? Maybe its your hated towards Bitmain telling you what to say, I didn't see you hating on the SP20s 300W stock PCI-E connections. But now of course you're outraged that Bitmain has the option to run 190W connectors to use less PCI-E connectors, or 125W connectors using more.I also enjoy how you're somehow blaming the entire industry using and being okay with 300W PCI-E connections on me as if its something I decided. People have been using 300W PCI-E connections for years and will continue to do so regardless of if you throw a tantrum about a PSU you had dying while running 80W connections.
It's not the cables that failed or the S2, it's the S2 PSU as I stated - yeah you've no idea what you are talking about.
Meanwhile,
My 2xS3 - one the cables are fine, the other the cables get quite warm.
My S5 - cables are all OK.
In all cases using high quality PSUs - not running above spec.

You probably were running those S3's in a cool environment .... I've had a few scrapes with singly powered S3 boards during the winter. The cables may be in spec when running at those speeds, but bitmain's testing is also based on average ambients, so low(er) ambients will result in better efficiency and higher power draws ....
Bitmain's testing is based off Eastern farm temps of 35-40C without evaporative. That's about the limit for an S4+ without risking them flicking off but the other previous miners can go higher without issue. That's not to say anything about the S5+'s performance or capability, I have not tested it.
More waffle than fact ... as far as I know, 25C is the stated rating ambient (for power draw cum et al?), with a recomended 35C operating ambient. To me that says tested at 25C.
You really are a chancer. What reason do I have to know "bitmain's testing protocols" (whatever that means) if they clearly state the basis for their specifications' ratings (ambient inclusive)? You really do not need to know more than that, just read the specifications ... (no wonder bitmain customer service is down the drain if they count you amongst them, you fraud).
So where did you pick that nonsense of Eastern farm temps of 35-40C other than the need to waffle no end, when you could have read it off the specs? By the way, no need to answer, I tired of your tripe.

They didn't insist on anything, it was arbitrarily inherited from the rev 3+ S3 board which had 2 PCI-E connectors per 160W board. And its not a rare thing, look back in this thread, plenty of people (including me) running S5s on single PCI-Es.
You say that like the board design was unchanged between the two.S5 is a stringed power design, S3 had voltage conversion, which implies AT LEAST a major redesign if not a "from scratch" design of the S5 hash boards specifically including the power circuitry. There was no "inherit" based on looking at the COMPLETE REDESIGN of the power setup for the S5.
bitmain should have been running 8 pin pci-e plugs since the s3.. this is from a seasonic 850 watt psu, running 2 s3s.. running at 225 speed. this psu came with 4 PCI-E cables with 2 plugs each.. so all 4 of the pci-e plugs on the s3s were plugged in. as you can see, it melted.. the s5 uses more power from the pci-e then the s3 does.. any plug in style the same as this will eventually melt..
So you were running 620W over 8 PCI-E connectors (77.5W) and it melted. Maybe you should both consider that maybe its your Seasonic PSUs that could have a problem, not the rest of the world or the other 10,000s of S3s. Jump to:
