i give my x2 6000+ and tiny bump to 3.2ghz once in a while...but most of the time I have it running at the stock 3.0ghz just cuz I dont want to risk anything with the stock fan...it does fine at stock speed anyways
Phenom II 940, stock 3.0ghz OC at 3.6 stable, custom water cooling from the den. Temps Idle at 28C, temps rarely see 40C full load
Phenom 9850 B.E. stock 2.5ghz OC at 3.0ghz stable only on Windows 7 RC 64 bit, with Rosewill 92mm 6 pipe, with a 120mm fan I put on it to replace 92mm. Temps Idle at 37C and never see above 50C full load.
