Hi i get some problems with my mining rig
Since i added 2 gpu (Sapphire hd7950) my rig became unstable. When i launch cg miner it work well but after a few minutes 2 of my gpu start to fail, khash are changing constantly between 450 and 510khash, the 2 others card are working great btw but after a random time i always get a bsod
I'm running these gpu on a Asrock h61 btc pro mobo with 2X2 go of ram, i got one cooler master V1000 psu for 3 gpu and a cooler master V850 psu for 1 gpu and i'm using powered risers.
I also plugged the 2 SLIpower molex on the mobo
When i disconnect 2 gpu it's working well, it's really when i start mining with 3 gpu that problems occurs.
I'm not overclocking the gpu, running them at stock clock, Engine at 925 and Mem at 1250mHz.
My .bat is the following :
cgminer.exe --scrypt -o stratum+tcp://freedom.wemineltc.com:3334 -u kewomot.amd -p t --thread-concurrency 21712 --gpu-engine 925,925,925,925 -I 17,17,17,17 -w 256 -g 1 --gpu-fan 75,75,75,75
Thank you
