Maybe you have C1E enabled on your BIOS. You have to disable that xD

The CPU speed is being adjusted to save power because the CPU is not being used at that exact moment.
Disable "CPU speed controlled by OS", and any kind of other BIOS power-saving features.

But honestly, this will not impact performance - run any kind of stress testing software and watch it jump back up to what it used to be....


edit:
You have to be able to at least access the BIOS, but if something is locked, then you're SOL..

i think the "locked" ones allow you to change the speedstep to disabled. Also Win7, I think you can change it in power settings to max performance.

I think it maybe a combination of EIST, C1E, and TurboBoost

xD

Just went into the BIOS and the only possible thing was something called AC power saving
