Q6600 underclocking itself even though speedstep is disabled

Hi, my CPU is overclocked to 3.0, however in CPU-Z it shows it much lower around... 2.1 and it sometimes just fluctuates but never goes above the stock 2.4 Ghz. My temperatures are good (40-50C) and Intel Speed Step is disabled. Windows reads the processor at 3.0 Ghz.

I'm not sure what to do?

Here's my PC:

ASUS P5Q Pro Turbo
Q6600 2.4 Ghz @ 3.0 Ghz
Corsair Dominator RAM 1066 (2Gb)
800 W OCZ Gamestream PSU
Nvidia 8800GTS

Have you tried pushing your CPU to 100% to see what speed you get?

I just used Super Pi and the CPU does actually surpass the 2.4 to the 3.1 Ghz I have it overclocked to. But, I would still like to know why it is underclocking, and i would rather have it constantly at my OC.
