Am I missing something? You'd spend $300 for three PSUs to run the blades but you can get an EVGA G2 1600 for about $320 and it'll power the whole thing with a 10 year warranty. I don't see why you wouldn't just go that route and have "one switch to rule them all".

Well, my batch 3 is running now on 2 HX850's.  And I haven't burned the house down yet...but since the overall draw is 1293 at the wall for this one, I think 3 is the way to go on it.

Each hash board pulls 400 watts so you should have at least 600w per blade using the 80% rule.
One 850w would not do on two boards.
I would do 850w+850w+750w for blades 1+2+3
I use 1000w for each of two boards. So three 1000w would cover two s7's.

Well, 4.825 btc lighter, I went ahead and bought batch 8 so I can finally replace my last S5 and S3.  I'm going to have to bite the bullet and buy another psu since I don't trust 2 hx850's to power this one like I did my batch 3.  But oh well.  I can get a new RM750 for $99 so it's not that much.

I just hope this one performs as well as my batch 3.  That thing is great.

That Temp and HW are way too high.  I would be doing a reset and an increase on the fan speed.  Thanks for sharing this test with us.  There is hope for the B7!!!

wow, 700 frequency.ain't that too high ?it only gives you extra 200 GH/s and a lot of HW errors 0.1 %.
Can you try with 650 Mhz instead ? I belive you will get better results
Your temperature is also too high, it exceeds 70c, you are close to danger zone.

P.S. You may want to higher fan speed if you are on manual

What's your fan speed?

Playing around with different clock freqs. Here's a snapshot from my current test.

Any guesses when the next batch after 8 is out for s7? looking to buy one in next month but batch 8 really isn't my favorite so far for spec/price wise. I'd buy one for about 1400 sure, but 1650 I feel is just a bit much

Yeah but in all the cases above the buyer didn't even ship the units back! I got screwed in this way on ebay years ago. I had an account with over 200 feedback, all positive, and had it since the site started back in the late 1990s.

Once ebay over tripled their fees they went downhill quick. You used to be able to ban people with under any number of feedback from bidding on your auctions which I always did on high value items $1,000+, at least over 10-20 feedback I remember for sure. Not anymore. You also used to be able to send negative feedback for buyers, which kept them in check. Not anymore. The buyers started to send me negative feedback for the stupidest things after that, basically ruining my perfect account. I had to kiss ass and give kick backs just to get the damn feedbacks removed, much like the feedback scammers on Yelp. They really get you by the balls and it sucks.

The final straw for me was when I got a charge back for a very large ticket item, and never even got the item shipped back to me. They went and took the money straight out of my bank account one day. It overdrafted me and made it so that my bills, rent, and everything that month were screwed up because I sold the item to free up the cash for bills and rent and the end of a hard month.

I hate ebay now when I used to love it and stand by it. I used to make almost all of my purchases and sales on it religiously. Not anymore. I'll use it for a few things if I have to but only as a last resort. I mostly only buy now as I can't take the risks associated with selling on that shit site. They really ruined a good thing.

Some of it on ebay is probably NOT an intentional scam.
Just some hopeful newbs buying a machine that they don't really know how to handle, then messing it up and running to the protective cover of ebay (apart from the obvious OP case).
NOT as described-sure, after they burn it down by using LIVE connector (see Phil's posts about this problem) to controller after misinterpreting bitmain's ESL instructions (much better than my chinese, admittedly).

What was sold is completely irrelevant.  It was sold for fiat using fiat transacting companies.  What's the point of fiat if you have no protections?

Jeez guys, do you guys realize what you're talking about?
Selling a device designed to make open uncontrollable currency , and at the same time complaining, that there should be more control and oversee?
You guys for real?

yeah I meant when you search on ebay all you see is really high prices (add shipping) for s5 or s3.  its true fees are high, but i sold some stuff (not bitcoin related) and once in a while you get reduced fees, etc.  

edit: looking back at my last comment, "scam" might of been a bit harsh ด็้็้็้็้็้༼◉Д◉༽ด็้็้็้็้็้

Be careful with Teamviewer. As they do have a "free" version that will eventually change to a subscription model one day. This is entirely a speculation on my part, but usually when a software is free and gets really popular they either get bought out by another company or the free goes away.

OK I was thinking you had reversed but for some reason I had it in my mind that paypal was 4%.  Is it less for ebay sales through paypal then a normal paypal transaction?  Or maybe they reduced it?

Which means you may need to swap PCI-e cords to the boards AFTER you have shut off the PSU.  DO NOT turn on the PSU until all PCI-e cords have been swapped to determine if it's bad cords or bad rail in the PSU.

We are also assuming you have tried a soft reboot from the system menu...  Sometimes, that's all that's needed.

Looks like no power to the last hashing board. (far left looking at the front of the miner)

I had bought a week ago antminer s7 but one chain problem and hasrate 3000 ~ghs working..Please help me...the following problem photographs,

You can get occasional deals like that.

Final value fees charged by eBay are normally 10%.  This does not include any possible listing fees.  I had it reversed.  PayPal is normally always 2.5% for anything sold on eBay.
