Hey guys I'm having trouble getting my 7950 vapor-x higher than 160 kh/s. Have tried running with -g 2 but it automatically disables 1 thread. I also can't seem to be able to run vertminer (neither 0.5.2 or 0.5.3), when I run the .bat it closes instantly. So I'm stuck with cgminer for the moment.. Any thoughts? Win 7 x64, 4gb RAM, Sempron 145
