Anyone running Win 8 yet with all Speedstep/EIST/C1E stuff enabled?

My MSI P67A-G45 board with i5-2500K is refusing to throttle down if I attempt any overclock. Win 7 worked fine and it would always pull back to 1.6GHz as expected.

My current OC is 4.2GHz with no voltage changes. Yeah, I know, a real wuss OC for you guys. But it used to work fine.

The weird thing is I can set the multi to 33 in the bios, get into Win 8 and then raise the multi with the MSI Control Center. Speedstep continues to work fine. It's almost like Win 8 does not like the initial mismatch between what is being reported and the actual speed?
 
My 3820 is overclocked to 4.3 ghz, and I see it idling at 1.2 ghz in CPU-Z in Windows 8. Using a MSI X79A-GD65.
 
i7 2600K at 4.5 idle around 1.6 ghz with no issues on windows 8.
