I'm having issues with my 7950 rigs. No matter what I try, none of my 7950 cards (all 16 of them) will run above ~600Kh/s. Here is my current command line:
./sgminer -k darkcoin -I 18 -g 2 -w 256 --thread-concurrency 24000 --gpu-engine 1050 --gpu-memclock 1400 -o stratum+tcp://east01.us.trademybit.com:4440 -u x -p x --api-listen
I'm seeing people getting ~1.5Mh/s+ with the above settings but I can't seem to replicate it. The only thing I haven't tried upgrading the drivers. I'm on Catalyst 12.9 running Xubuntu 12.10.
Any ideas? I think I'm basically down to upgrading the drivers but I wanted to get some input before I go down that long road with Linux and mining cards...
