6950 11.4 overclocking woes

post #1 of 7
Thread Starter 
Alright, I'm in the middle of doing some open cl stuff, and I realize that it's not running at the speed it should, I check MSI afterburner and my clock speeds are jumping all around, all the way from 750 to 925 (925 being what it should be steady at). I open CCC and check and it doesn't report core clock speed, so I adjust the power slider and it locks in my OC in afterburner at 925.

This a known issue, or am I going crazy?

When using AB, you want to keep CCC disabled, so the programs do not conflict. (Also check MSCONFIG to make sure CCC doesn't run on startup).

Yes it is a known issue. Using Afterburner to OC out of CCC parameters will disable CCC power control, causing your GPU to throttle.

Best thing to do is unlock CCC to allow higher clock speeds. For HD 6950 Unlocked its 950/1450 now i have it @ 1620/2500 lol.

Forgive my double post, but that doesn't seem to do anything. I'm having the same issues. This wasn't a problem at all until today when I had to reinstall windows.
