Anyone powered his S7 using only 1 PCi-E 6 per board ? I have powered them with only 1 cable per board for the last 2 days and they were working fine Just today I read somewhere that it actually needs all 3 cables per board.
wow that's gutsy. cables not getting warm?

I Dont know why but when I set manual fan speed on my S7 B2 its not geting above 1.5th after setting fan back to auto its at 4.6th. Just tried setting it to 70% for 5 min but still its strange isnt it?

Does anybody know of any decent data center for miners in Southern California?
I have no clue where to look for a data center ( with the exception to a multi-level underground nuclear hardened facility out in Iowa ).... what questions to ask.... what to watch out for.... etc. I would think that data centers would not like to have average joe schmos putting their equipment in their centers that have large corporations and what not hosted there.... just out of security sake. great north data is really pretty good http://www.greatnorthdata.com/https://bitcointalk.org/index.php?action=profile;u=400812Canada Based. My next order from bitmaintech and or avalon will be going to his place What are they charging per kw? assuming you buy like 10,000? Any setup fees or other maintenance fees? The last quote I got from Great North Data was $60/KW but you had to have a minimum requirement of 30KW in equipment. I wanted to send 20 S5s to them but that was only 11-12KW and they would not take it. From: James Goodwin [mailto:james@greatnorthdata.com] Sent: Monday, May 11, 2015 6:40 PM To: Carl Grissom Subject: RE: Re: Hosting Inquiry
Carl,
I'm very sorry, but I've been talking to my business partners and they would like me to only sign contracts for at least 30kW. So I'm afraid we cannot take your machines. Sorry if I have wasted your time, this was only decided today. I could probably offer a slightly better rate if you were able to get to 30kW in demand.

It seems only 1 board is working; I would suggest trying a software reset after changing between auto and manual. Also I would turn the manual setting to 50% or below.

Hi, I'm based in Canada too and I do hosting. My rates are (Taxes included) 74.73 CAD which is currently ~ 57 USD / kW. I don't have any minimum and I'm currently working on a new website where customers will be able to manage their miners. There is no minimum needed.. (Why would there be...??) My website is currently http://cryptominer.ca . Just PM/send me an email if you are interested.

Running against nicehash. S5's would every so often crash the os against nicehash as it was switching rentals. My remote pdu allowed me to cycle the power and bring them back up. The s5's are gone now.
Just now my first s7 had the os crash with nicehash. Did the remote pdu power recycle and it is back hashing away. More of an impact when 5th are taken out rather than the 1th.
Now I only have a single S7 but haven't had this issue before. Up 2200 minutes still with nicehash.

Seems like negative amounts each time I look at site. I think you would make more off a standard pool. But I could be wrong on this. It's currently -8 percent compared to mining BTC.

That's over 350W DC for 1 cable. The connectors/pins are only rated for a maxijum of 324W, and those ratings aren't overly conservative given the demanding environments mining puts on them (vibration + high ambient temps). Plug more cables into them, like now... Edit: Plus it violates Bitmain's ridiculous warranty terms...

Considering I usually mine on slush and their luck is down, I'm making more on nicehash than I would be putting my hash at slush. I move back and forth though. I'll probably test my luck on slush again because good days there are nice on the wallet. nicehash is just a steady stream even though it's not ideal. I much prefer renting my hash out on MRR though.

Pretty stable usually. Payout pretty good on MRR? That's the problem I had, luck would go in the toilet on regular pools and I had 45 s5's. Got tired of switching. I have used putty in a batch file to shift pools and reboot on s5's. I have used a proxy server (the java one on ubuntu) but I seem to get a lower payout with the proxy. Need more time to play.

That way I can use 2 dell 750 PSU with 8 cables. Using high quality 16awg cables and breakout boards. No issues. Been monitoring temps of connectors and cables. Avg connect temp is 79F. Miner runs at 55-59c and ambient temp is 69-72F. That would be 175w per cable on the boards with 2 plugged in. Consumer PSU may not handle this since cables are lower gauge and will heat up more.

Pretty stable usually. Payout pretty good on MRR? MRR can payout good. Depends on what you set your rental rate at, I tend to set mine a bit higher then 100% and have had good rentals, but not much lately with the increase in hash network-wide and high diff. I like MRR too because I point all my miners to it and it proxies my connections so switching pools is a simple mouse click and all my miners switch together rather than having to log into each one and manually changing the settings.

Can you use their proxy to switch all your miners to any pool? Even if not renting? Sounds like an easy way to flip pool all at once on your own gear and pools.

The wire gauge on the bitmain 1600 psu's is pretty teenie. Maybe that is why the "three cable rule" is pushed. My corsair rm1000 modular cables are pretty beefy. I use two per board with the daisy chain from one of them, filling all connectors. The board next to the controller socket gets the daisy chain from the second cable.

Can you use their proxy to switch all your miners to any pool? Even if not renting? Sounds like an easy way to flip pool all at once on your own gear and pools. That's exactly why I use them. You can set up 5 pools and you can turn off your rentals if you don't want them to be rented (or just price them really high so if they are rented, you're making bank). All your miners are set up to MRR through their web ui, then on the MRR page, you simply select which pool you want them to mine while not being rented. And if you have a lot of miners, that saves a lot of time. But I have to add that they all mine the same pool, so you can't have 3 mining on one pool, 5 on another...all 8 would be on the same pool.

wow that's gutsy. cables not getting warm? I'd also be worried about the connectors, sure they'll be overspec'ed but not infinitely.

One is asking for trouble. I imagine it will get pretty hot, and your talking about possible burning with 1. Get a better PSU and use more then 1 per board, is best advice.

I thought I fixed the issue this weekend but that wasn't the case. It should be fixed now. The website is very minimalistic, but it's in my todo list to improve the company image. I'm currently busy building the backend for now..
