Ah, then it could be a problem in your Windows installation. Anyway, just for the history, i have APM off, turbo off, Cool N Quiet, C1, C6 enabled. Unfortunately, if you 've done something to your registry or something to your core behaviour, i don't know what to tell you. It's not normal to use only 2 P-states...
