Rig stats and pics
-
On the back of the 2 cards on the mb where you have the card outputs i have a pc fan blowing into there should i have that the other way around if the fans on the card are pushing the hot air into the colder air coming out of the fan?
-
2x5850’s using cgminer with the standard scrypt config. Nothing special. Both cards OC’d a little. Getting around 650Kh/s combined but I am solo mining.
-
How are you getting on with solo mining? I had all mine going for a day or 2 before the inrease in difficulty but didnt hit any blocks :(
-
tbh you’re gonna struggle with those cards plugged directly in to the mobo. The air gets diffused all over the place rather than neatly out of the backplate (connector end) which is fine for a single GPU but useless for multicard setups. Raising the card so i can suck in cool air rather than the hot air from the back of the card in front (clue: shut down the rig and feel how hot the back of the card is) will help hugely. I tried the 120mm fan trick but ended up with a bunch of 12" desk fans.
Go to page 4 of this thread for some pics… Pyxis uses 4x 7950’s and i use 4x 7970’s and we both came up with the same(ish) designs although Pyxis looks more refined ;).

Thanks for the help, will check it out and see what i can do.

[/quote]Jeese Nut, just seen your rigs, what is the total combined wattage of all that? Gotta be touching 6000/7000W+ what are you plugged into? The Cooker or Shower ring main? :D
-
Just shy of 7000w including the fans and the AC unit which runs on fan only mode most of the time (anothe 1.5kw when it gets too hot).
All running from the neighbours shed! :-X
-
Several machines running multiple or single cards at PC repair shop in Burbank.
7950 -550k
7850 -345k
6870 -365k
7770 -120k
5770 -140kSome of the systems are being used for data recovery too offset Cost of mining.
My PC repair shop is located at 340 N victory blvd. Burbank CA 91502. 8184506705 if you need a quick help with mining hardware.

[/quote]Lmao, I hope it isn’t mine ;D ;D ;D

Joking aside i have a separate 40A breaker at the house attached to ~50m of 10mm SWA that runs down to my cabin where there’s another CU that has 2 circuits for the miners (3 on 1, 2 on the other). I did try them all on 1 circuit for shits and giggles but the 2.5mm T&E got rather hot! :-[

[/quote]Yeah man it would get warm, it’s only good for circa 22Amps you are pulling around 30Amps :D
I wired my shed up to a 30Amp breaker on the MB, I have my own little hobby workshop in there, complete with compressor, welder, spray booth, temp controlled curing cabinet (except my miner is currently set up in that :) ) -

Hey guys :) updated the thread to include pictures. Please submit your pics I would love to look at your mining rigs and I’m sure others in the community would love to as well. Each week I will pick one picture which will go on the main page of this thread and will be called “Rig of the week”. The rig of the week winners will receive a 50FTC reward for their picture. Please include your Rig stats (Cards, KH/s, Temps etc) and your FTC address.

My single 7850 doing ~370 kHash/s at 64 celcius temp.
[just noticed 4 HW errors. Crap…] -

Stats:
1. (1) 7700 - avg 133 k/h - avg 76f ( I use this one )
2. (2) 7850 - 645 k/h - avg 60f (One died, waiting for replacement)
3. (2) 7850 - 600k/h - avg 78
4. (1) 7950 - 515 k/h - avg 73f
No overclocking and zero hardware errors on all of them…

Edit: Blah! Sorry the pic is so big!
Edit Edit: All of them are running Debian 7 with cgminer 3.1

Which 7850s are you using here? What options are your passing?
I can’t get over 530 on mine.

I am running Gigabyte and MSI 7850’s and that is both cards combined I posted. MSI is getting 300 k/h each and the Gigabytes I’m getting 343 k/h each when it is full speed, but I am waiting for a replacement on one of the Gigabytes… No overclocking and zero h/w errors…
Edit:
Gigabyte - Thread Concurrency = 8192 Intensity = 16 no-submit-stale
MSI - Thread Concurrency = 8192 Intensity = 16,20 Shaders = 2048 no-submit-stale -
My Stats:
2x 6970 501k/h each, total 1000k/h
Temp: 90/87 degrees
Did a bit of overclocking, 950 on the GPU and 1450 on the MEM -

[/quote]Well I’d like to nominate nutnuts rigs, a kickass ::) 15Mhash ::) setup that could have been mining other coins with but instead chose to mine feathercoin. :)
