ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

Here is the difference between stock firmware and oct 23 600 firmware running 15 s7's against nicehash.
If you look at the start on the left for about an inch that is the stock firmware running.
After that all oct 23 firmware. The downward spikes are rebooting on my end for naming configuration.
Two more s7's from oct 12 order will arrive tomorrow.

Thanks for the image tip dmwardjr.

what's green and what's blue? are we comparing first inch of green with the rest of the green or first inch of blue with the rest of blue?

Very interesting. I assume everything was set the same, Frequency extranonce etc? Would be instructive if Bitmain would let us know what the differences were?

The green is the pay rate which you can't see in the graph.  The blue is the average hash of the miners, show in Th on the right.

Well if I can run one of these bad boys off of 2 HX850's, I am going to have to sell my last S5 and S1-S3+ upgrade (OC'd and hashing at 500 which is sweet and reliable) just to get one out of the next batch so my 4 HX850's can be used.  Guess I'll have to test it first to see if I can reliably do that.  I worry about pumping 800 Watts through a PSU that's rated 850 Watts.

It would probably work, but the S7 I'm running of 2x PSU's are a lot more unstable than the ones I run on 1 PSU. 100 GH/s lower as well, and can't handle overclock at all.
100 GH/s more on the ones I run of Bitmain's PSU and an EVGA 1600W G2.

Multi-meter readings show a 0.1V difference on the dual PSU setup, compared to 1x PSU. So the problem might actually be that the PSU's themselves. Running 2x boards on XFX1250 and 1x board + controller of a cheap ass Corsair 650W.

sorry, but first inch of blue is essentially at zero-so, it did not work with previous software, but works with current or you are talking about a second inch compared with the rest. i see some increase there (maybe 5% or so).

Everything identical, extranonce of course.
Would be nice for a blurb from bitmain but "works better" comes to mind.

I just received a shipping notice from UPS for delivery tomorrow for an order from 10/18; although, it is still showing Unshipped in Bitmain.      I still have more orders on 10/24 and 10/25.

was it b2 or b3? it would be helpful to know.
my 10/16 b2 order is still nowhere to be seen.

Why did they make batch 2 available anyway if they don't deliver it at least on par with b3, without even considering that one might expect b2 to be delivered BEFORE b3 as the common logic suggests.

The order was for Batch 3.

sorry, but first inch of blue is essentially at zero.

First inch of blue mass where the new miners are running.
First inch is just below 75TH, after that pretty much right on it.

Hmm, well I'll definitely have to do some testing with my 4 PSU's on my B3 that's coming tomorrow.  I was originally planning running 3 PSU's with it, 1 for each board +controller.  I know they can handle that.  But if I can squeeze out enough juice to power a second S7, I'd rather do that than my S5+S3 combined mostly for the energy efficiency when it comes down to it.  If I have to consider a new PSU, I'll have to evaluate that cost with the next S7 batch to determine if ROI is possible.

I worry about pumping 800 Watts through a PSU that's rated 850 Watts.

In theory, you should have no issues with pumping 800W sustained out of an 850W power supply. 50W is a decent margin.

So an HX850 should be fine, the only difference I see is that the RM850 is fully modular while the HX850 is partially modular.

Yes the second inch, 5%, thank you for clarifying that for me sir.
I watch these graphs all day every day so I took way too much for granted on the explanation.

[Xian01]

In theory. The initial RM750's and RM850's were a bit notorious for running into thermal issues and potentially causing all sorts of havok. I believe Corsair has since replaced the inferior components they were using in the RM series.

80% is max I would do for safety. 60% is safer.
I'm running 3 corsair rm1000 watt psu's to power two s7's, that is at 80% for two boards on s7. At 80% it keeps the fan running slowly to cool.
When you drop $2000 on a rig, don't skimp on psu.
Even a corsair AX1200 is good. Good price on ebay.

But an AX1200 can't power a single S7 since they use 1210W.

Correct, that would be for two boards.
Here are corsair rm1000 used I just googled. $115 shipped. Half of mine are used.
