Hi All
I would really love some help solving a problem I am having with my rig. I just installed my second GPU (Gigabyte 7950). Each GPU will mine fine by itself but when I try to start them both my system immediately crashes. I have been using bitminter because of it's ease of use but trying with guiminer I had the same results. I have never been able to figure out cgminer(?). any help at all would be appreciated.
MOBO: MSI 970a g46
GPU's: Gigabyte WF3 Rev2 X2
AMD Sempron 145
PSU: 850W
I am at a real loss here. Should I try the crossfire cables?
Thank You
Throw away those crossfires, guiminer and bitminter.
Learn to use cgminer or bfgminer. Setup both cards with default clocks. Download GPU-Z to view the RT clocks.
Once you have them both running with the default clocks, increase core on both until you get h/w errors. Back down with core a bit, start lowering memory until you get significant drop in hash rate.
Download MSI afterburner to set clocks to whatever you want.
