post your errors guys & gals.
most of mine are no more than 0.001%
what's your highest & lowest ?
any difference between miner & pool side ?

Anyone try connecting 3 S7 together yet? Since they have the extra FAN and Hashboard connectors like the S5+. Would be cool, just 1 network cable to run and good for failover should 1 controller die.

I'm using a AX1200 to drive two boards and the controller and one RM750 to power the other hash board. Just making sure this is fine to do. Both running on 240v same breaker
That is the incorrect way of connecting it and may cause damage if you don't do the power on and off order properly. Please see the User guide P4 which will show you exactly the power on and off cycle and how to connect it. Using 2 PSU that you have is fine, just have to do it the right way. The AX1200 is a very pricey PSU, and since you have 240V, why not sell that PSU and just get a IBM server PSU with J4bberwock board? You can power multiple S7 for much cheaper per S7 and you don't have to worry about the power on and off order as you will have plenty of connections available.

I had an ax1200 and rm750 that's why I'm using them. Got them about 6 months ago.
I did follow the boot up procedure. Powered on all boards before the controller. Boards 1&2 powered by ax1200 and board 3 & controller powered by rm750. The pci to the controller is delayed power via a relay for 5secs
Then you should be good. You mentioned a backward configuration initially.

Haven't bought any miners direct from Bitmain since the S3/S5 days and I don't seem to remember any such delays in fact I was nearly always generally very pleased with the turnaround times then again that was before they started adding these obnoxious disclaimers right in the Product titles like:
ANTMINER S7 BATCH 8 - Shipped out within 5 days with full payment
Speed: 4.73TH/S
Weight: 4.5 kg
Price: 2.51 BTC
( 996.47 USD )
Anybody opt for the $70 extra dollars in hopes that a Batch 8 premium price would buy a more expeditious turnaround in the order time like maybe even similar or close to the old days of the S2/S3/S5 days?
Is this a stupid question?
Thanks in advance

Don't bother. They will ship about the same date and you save $70. The Batch 9 unit also comes with all the extra Hashboard controller and fan connections. They are caught up on the shipping date as most remaining Batch 9 will be shipped out next week.

Can you power an antminer s7 off an evga 1300 and a corsair 500 watt psu? I'm thinking the 1300 for the blades and the 500 for the controller. Would this setup work?

Use this one you need to use your own wires just wire them up yellow=+ black=-
even has a variable dc output from 10vdc to 13.8 vdc This is what I use works great to.
here is the link for the PCI-E connectors. these are what I used very good quality.

Things that are happening in bitcoin right now and WILL affect our mining on S7:

https://bitcointalksearch.org/topic/m.12409946
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)

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.

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.

January 23, 2016, 09:06:09 PM
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.

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.
Antpoool last month Luck
24 Hours 3 Day 1 Week 2 Weeks 1 Month
106.00% 108.00% 111.00% 107.00% 103.00%
https://www.antpool.com/poolStats.htm
and it claims lifetime to be 100% lets say that is true
kano.io claims lifetime to be 104.33% lets say that is true.
so an antpool miner that earns 100 coins before fees before fees = 97.5 coins after 2.5 % fee and no transaction fees so total of 97.5 coins
a miner that mined with kano would be getting 104.33 coins = 103.39 coins after .9% fee and about 4 blocks worths of fees say 1 more coin 104.39 coins
so a big time miner not in China is getting 97.5 coins after fees at antpool and a bigtime miner with kano would be getting 104.39 coins
So I get if you are in China why mining at antpool makes sense due to firewall issue. but 97.5 coins vs 104.39 coins no contest where anyone should mine.
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.

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.
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.
Yes, very sarcastic post NOT meant to break or shatter ones delicate nature.
Disclaimer: My numbers could be off by %50.
I still think Pluto is a planet.
