something must be wrong with catalyst 11.7... now I have 16% - 17% cpu usuage on my 6 core amd phenom II. With catalyst 11.6 I had about 0% cpu usuage.
Now I have 11-7_vista_win7_32-64_xcode (the video converter) installed aswell, I don't remember if I did have it with catalyst 11.6.
Very happy with the performance on my HD 5870 with the latest update. I can get identical speeds on poclbm (~450 mhash/s) as I can on phoenix's phatk, except poclbm is drastically lighter on the CPU than Phoenix is. Great work, definitely worth a tip.
How do you get that much (450 mhash/s)? I can only get about 400....
I have the problem with catalyst 11.6 drivers and youtube while mining with my radeon 5870... it downclocks my card to 400Mhz.. then I close the youtube tab in firefox 5 then the gpu clock goes up to normal again.
