PhenomMsrTweaker: Cool and Quiet customized

[mattkosem]

Is there some trick to getting the powersaving state working with CnQ disabled? It doesn't ever kick into the lower profile on my system with CnQ disabled on my system.

Actually, there is a possibility to enforce a enabled P-state (and P1 is enabled, even if Cool and Quiet is not). This is why the tool is able to apply changings to a currently active P-state: it temporarily switches to the other state, saves the modified settings for the target P-state and switches back, applying the new settings.
But is there a good reason for having Cool and Quiet disabled? Is there no such BIOS option or do you use an OS with a crappy driver? You could enforce P1 by using CrystalCPUID's MSR Editor and setting the register 0xc0010062 to 0x1 (eax, edx: 0x0). If there is a popular demand for enforcing P-states, I could add this functionality to the tool.

On my board, and presumably others, having CnQ enabled with a NB frequency over 2600mhz causes Vista x64 to be unable to boot. The symptom of the issue is a BSOD during the Vista loading screen. Given that issue, I'd love to be able to enable a lower power state with it disabled.
