do you think we'll make btc on pacmic 3?.
I bought 5TH on day one. So far so good.

So far, so good. Looking like I will get more BTC out than I put in at the completion of the contract.

yeah I think I will. but for now I stopped auto buy.

I need to focus on this s-7

how loud it will be-most likely too much for a residence,
i will probably try to order at least one to play with

Im so tempted to buy right away. But I should better wait for you guys to see what sound it produces.

Someone actually mentioned on the S5+ putting an inline delay device on the cable that goes to the controller so that it would intentionally power on AFTER the hash boards. I thought it was an interesting idea but he was wondering if that would violate warranty even though he wasn't modifying the device just putting another device in-between the the PSU and the connection. I personally think that should have been part of the controller design ANYWAY through firmware, by hey that's me. It just seemed a bit assinine to have an intentionally separate connection that another switch had to be flipped to power on a unit.

I do not think a delay is necessary, the words in the S7 document are slightly clearer than the S5+

Quote

If you use different PSU for hash boards and control board, please make sure to power the hash boards first and the control board only after the hash boards have been powered.

The key bit being in bold and although not exactly what it says I would interpret as being that Control & Hash can be turned on simultaneously, the only NoNo being Control first, Hash second?

1210 watts quoted "at the wall" - an EVGA 1300 would have about 10% power reserve, even my favorite Seasonic X1250s have some power in reserve.

Indeed. Some of the more common official peak ratings are in my PSU guide, although for 24/7 its still going to officially be the stated rating. That being said, I've ran many corsair PSUs past their limits in challenging conditions and they've done fine.

Only if you can run each board on two instead of three connectors, contrary to bitmains instructions.
However, they said to use two connectors per board for S5 and some people used just one successfully (with a good quality connector such that found in EVGA).

I'm using an EVGA G2 gold 1300 now with two S5s and it's running at roughly 93/94% efficiency. Per my 'at the wall' meter. all red VGA cables used, vertical strato setup with a box fan. I just checked this. Was running at like 97% efficiency when only was running one Tongue

, but lot less load.

good, but it doesn't actually answer my question re using 2 cables/board instead of three. EVGA 1300 has only 8 connectors and you need one of them for controller, so that leaves 6 left for three boards in S7-will it work? I guess that we will have to wait until someone does it first (my money is on Philip since he was always a fan of evga).

Maybe that can be in batch run 2. (HINT HINT Bitmain)

I see people asking about coupons. Don't hold your breath. It's a new product and the first batch went quick.
Bitmain does not need to offer coupons until/if sales slow.

the first batch will be there only at 9pm pacific tomorrow, it wasn't on sale yet.

^^ so thats 8.4 months @ 0.1 usd/KWh lets say difficulty will be around 71b (+30% - thats a shot in the dark) then we will ROI in 9.66 months.

PS: awww, count another 500 bucks in for shipping + taxes. so 2 more months...

My usual spreadsheet, people have said it's been useful in the past.

Price doesn't include shipping, import taxes if applicable or PSU's. Assumes static diff and BTC price, it's just to give a rough idea

Mining still dead in the UK at $0.23, and shipping to a host is probably going to be a year to breakeven when the inevitable diff rises happen so no new machines for me Sad

Congrats on launching this, Bitmain ! Very impressive specs.

I'm more interested to see BM1385's voltage curve as we didn't get one this time. It doesn't feel like .25 is the limit and like the S3 to the S4 and the S5 to the S4+ we could see even high efficiencies on a theoretical S8.

They have shown us three points on the curve with :-

0.71V 0.263W/GH
0.66V 0.219W/GH (S7 / 18 Chip Chain with 12V supply)
0.60V 0.181W/GH (S7 / 18 Chip Chain with 10.8V supply)

The S5 with BM1384 bottoms out at 0.6V. I do not know if being full custom opens the way to a lower core voltage but my guess as both BM1384 & BM1385 are 28nM is that BM1385 will also bottom out at 0.6V?

Very tempted to purchase one of these units, but this round, I think I'm going to purchase $1,823 USD worth of BTC on Coinbase when these go on sale instead.

Have ~22THs wrapped up in PACMiC v3 anyway. I would be very interested to know the underclock potential of these if they were running @ ~1kW each.

Congrats on launching this, Bitmain ! Very impressive specs.

Let's hope for some coupons

I'll be interested to see if coupons materialize. My bet is that they won't. I think Bitmaintech is a different animal than they were 12-18 months ago. Maybe coupons if the S7 doesn't run at spec, but I'll bet that's very unlikely, since I expect they already have plenty of experience running them in-house (e.g. Hashnest).

If anyone wants to run a few of these machines, but doesn't have the capacity, we at http://toom.im can take some. We can provide a server-grade PSU with 16 awg leads for these for $80 each.
