Why does my rig crash (hard - very hard - like I have to run Windows repair to get it back!) when I use per-GPU arguments like this?
-I 20 -g 1 --expiry 20 --scan-time 20 --thread-concurrency 21712 --gpu-engine 1100,1100,1145,1145 --gpu-memclock 1250,1250,1750,1750 --gpu-vddc 1.106,1.106,1.113,1.113
I have two pairs of 7950s in my rig - 2x Twin Frozer in the first two slots and 2x VaporX in slots three and four. When I run the same settings across all the GPUs with over clocking and undervolting set in MSI Afterburner, like the following, everything works OK, but the VaporX GPUs hash slower than they should:
-I 20 -g 1 --expiry 20 --scan-time 20 --thread-concurrency 21712
I disconnected the Twin Frozers and tuned until I came up with the best clock speed and voltage for the VaporX'es, but I can't figure out how to have different GPUs run on different settings.
