I'll have to buy water cooling if want 3.0ghz on 64 bit.
The best I could get with my 9850 was 2.95GHz stable and some runs at 3.0GHz under Vista 64bit and that was @1.55v with water cooling

With 32bit OS's I could get up to 3.255GHz stable

The red circle in AOD is CPU Tweak
I found it best to keep it enabled for overclocking

You probably better off to disable ACC
If you can get past a 300MHz overclock you probably don't need ACC
