Is it better to run the S7s at 12.75v instead of 12.5v from the 2880w psu? Not overclocked B9s. Can it hurt the miners? Thank you.

no if you are providing 12.5 volts at stock freq you should have almost 0.0005 errors what do you get with your 12.5 volt setting at stock freq?

I will receive them on monday, I'm preparing the rig to receive them. The 2880w psu can be jumped to raise the voltage 0.25v more to 12.75v. Normal voltage is 12.5v. My overclocked SP20s runs at 12.75v without issues and they hash really strong with minimal errors but the S7 seems to be less reliable. Thank you!

and since they never compensated me for the low hashing batch 1's i received I do not buy any for myself anymore.
The last one I purchased for my self was a batch 2 that is rated for freq 575
I still feel they owe me about 150 usd in compensation or maybe 134 usd. I asked for coupons not coins,
They blew me off so I no longer buy for myself..
I also ended my mining in China over this. Frankly I don't understand why anyone not in China mines on a Chinese pool when kano.is has proven to crush the Chinese pools.
Me and at least 2 others have not received any compensation still either for the Batch 1 fiasco...

Frankly I don't understand why anyone not in China mines on a Chinese pool when kano.is has proven to crush the Chinese pools. You are right about being upset about this, of course. That said, maybe look at it from a karmic sense/perspective. You got low hashing B1, then you got very high hashing B2 (I remember that you said they could do 625 instead of 575). Maybe it was the universe smiling at you for B2 or maybe a friendly product manager at Bitmain- who knows? In essence, these two purchases are balanced, don't you think? Of course, coupons would be a nice gesture. I ordered pretty much one of each batch (stopped at 7) and my B1 performs very slightly below spec, but B5 can do 625 easily (5Th). So, averaging gave me what one should expect-average hashing in comparison with what was expected.

Anyone have different batches that can compare temperatures? Does Batch 8/9 run much hotter due to the higher overclocking or does the lower total chip count kind of balance things out? I want to see if someone who have the 162 Chip S7 compare temperature against Batch 8/9 with 135 Chips.

Prior to S7 sales Antpool was approx %18-%19 of network. Thanks to you guys that support diversity, they jumped to almost %23-%25 in just 3 months. Keep buying those S7's. Can't wait to see the growth after the S8/S9 sales. Good job guys. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Yes, very sarcastic post NOT meant to break or shatter ones delicate nature. Disclaimer: My numbers could be off by %50.

Here you go nhando, B7 and B8 screenshots, they are at sidehack's place and I am guessing they are on the same rack, fan speed is manual 60%.

I still think Pluto is a planet. People are kind of oblivious, everyone flock to the bigger agglomeration, its a survival instinct. By default the miners are set to Antpool, too and then they advertise 0% fee. So people thing the less = better. But Antpool keep the txfee, so the fee is much higher than Kano's 0.9%. The other thing is that Bitmain might be keeping a lot of S7 for themselves. It would be rather profitable for them to do so.

Thats correct math, except Antpool has a 0% fee. So 100% luck would be 100 coins. And Kano after 0.9% fee is indeed at 104~105BTC. So even with Antpool's 0% fee, you lose more using Antpool than Kano. Even if Kano would be at 100% luck overall, Kano would be superior, because the TX fee account to more than the 0.9% we pay Kano pool. And also Kano has a great backend, which help eliminating Orphans.

We are running about 100 of these units and the GLOBAL hw error state is of about 75%.
We have a huge number of hardware errors, on batch 6/7 miners at stock clock. Not sure where to go from that, these numbers can't be healthy.
Don't know what to do with this so far, other than downclocking but such high numbers aren't normal.
Wasn't batch 6 supposed to run at 600 mhz and batch 7 at 625 mhz default? Yes, sorry I had my numbers wrong. Those are Batch 8's. They come overclocked at 700 mhz per default, and have 45 chips per board.

We were using Minera as a monitoring panel and found out the HW error % is totally innacurate.
After checking back directly on all antminer's interface we have a decent hw error rate. However, if we overclock our batch 7's they tend to raise above.
Nevermind my point then, our HW errors are well within acceptable range.

EVERYONE, Please be careful of SCAMMER CCLIU or LUCKYPYRATE trying to sell you S7. He will pretend to use others for Escrow but then find an excuse to say it's a bad idea and tell you to use LBC as escrow. Don't fall for his trap. He have multiple accounts. Bottom line is, if he won't escrow with someone you trust, DONT FALL FOR HIS SCAM.

When you use escrow as buyer pick one you can agree with buyer on. Don't just let buyer pick escrow. If you do that your essentially defeating the purpose. Also if you get a PM without asking about buying, or shopping around very good chance it's a scam. Normal sellers don't sent out random PM's trying to get a sell for the most part.

Nothing to worry about. Bitcoin Classic is still in discussion phase and hopefully something comes out as a solution to the current issues and controversies regarding block size. AFAIK, both core and classic coins will be available for end users/miners. (Not sure about that though)
