On AMD CPUs, Cool'n'Quiet is usually disabled when you OC using the BIOS. The solution I use is to manually turn off C'n'Q in the BIOS, set the OC parameters (voltage, NB-CPU frequency, HT frequency, CPU frequency) appropriately and then manage P-States with PhenomMSRTweaker in Windows. I use the stock P-States for the Balanced power profile (P1-P4) and the OC'ed P-State (P0) for the performance power profile, so when I surf etc., the PC uses the Balanced profile and when I game, I manually switch to the High Performance profile. Works like a charm for me.
Best of luck with your OC efforts.

It's not true of my OC'd C2Duo hackintosh. It will throttle back to 6x333 = 2GHz when idle. Then again, it doesn't have the multiplier unlocked. How do unlocked Sandy Bridge CPUs do with idle speeds?

The FSB as you traditionally understood it is dead as the CPU has consumed all the parts. You don't really mess with BCLK anymore (you can, but the range of speeds can be rather limited).
You instead end up adjusting the turbo multiplier. So if you leave EIST and the various C states on, it rolls back the multiplier when idling.

Am I correct to say that I have to forgo the automatic speed adjustment by using this utility?
