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.
Only one once with 17 running against nicehash.
Can't even ping the miner. HAVE to power reset.
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.

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.

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...

I'm doing 8 total, 2 each to outside boards and 3 to center plus controller. 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.

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.

Why are you running on nicehash?  I can't figure out why people still are.  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.

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.

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.

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.

I can vouch for max having seen his setup and dealing with him in the past. He's straight.

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

What are they charging per kw? assuming you buy like 10,000? Any setup fees or other maintenance fees?

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.

Depends on the gauge wire on your PCI-e cables.  It's a bit risky to do it with only one.  Two 16 AWG PCI-e cords will do fine.  Mine are at room temperature with only 2 x 16 AWG PCI-e cords.  J4berrwock's 16 AWG cords are the ones I'm using.

Edit your title! there is no s7 available on your site at this moment!

I agree. They really should put more support in this thread since this forum is probably 99% of all their sales.

Bitmain, any plan to make a 2 board model with S5 style heatsink ?
That is probably what they are doing, there was a mention of a 3.x TH/s S7 somewhere in this thread. Something about being competitive with another 3,x TH/s miner coming out from another company

Interesting thing I noticed on my Batch 1 order I received a month late earlier this month.

I decided to change the airflow and vent into my garage for the winter since I live in Texas and we don't ever run the heater.

I chassis-connected all nine of my s7's that were delivered weeks after the Chinese holiday. I had noticed that two of the miners were always a little bit lower on 24 hour averages and seemed flaky. I have two miners that will randomly start throwing a mild amount of errors and switchover to my second and third pools, which I never thought much of to be honest.

When I took them all down from their prior mounts and connected them I noticed the rev dates on the hashing boards. I have seven 1.6 version boards, a single 1.5 and a single 1.4 board, guess which ones I am noticing the weirdness from...

Anyone else notice the flakiness from the 1.4/1.5 boards? After waiting for over a month I guess it surprised me that I got the older rev boards from B1.


Ufo

My early B1 is even worst, V1.3. So much for ordering early. 2 of the boards didn't work, later found out they have loose chips. This board doesn't work with controller with later version hash boards. My second B1 and B3 came with V1.7.  It does hash at 1.62 TH (running it by itself) on average.
This is good information. Do you have to pull the boards to see the revision?
I imagine the rear fan has to come off to pull the boards.
They are not connected to anything internally. Just the external hash connector and the three pcie.
And my middle hash board is not as snug as the other two.


I just checked my Batch 1 which was shipped about the 14-15th and all 3 boards are V1.5 and have had no problem to report. I run at 612 freq and get 4.85TH/s
The revision in on the hash board at the top at the back as you look at the right hand side of the board.
The one I just put a fan on has three v1.4 boards.
It runs 600 and 4.86ths
