Strange Q6600 Problem

I have a Q6600 with a big Zalman heatsink on it, OC'd to 3.0GHz. Idles at just under 50 degrees and goes up around 70 degrees under 4 threads of the P95 Small FFT test.

This is all fine and well, and were the numbers I was shooting for. However, (and it seems to happen randomly), the computer will boot and both CoreTemp and CPU-Z will show that the multiplier changed from 9 to 8, and the CPU is running at 2.6GHz.

I'm relatively new to overclocking, so maybe this is a common problem.

Any ideas?

Its not a problem,there is a feature in BIOS called speedstep,when enabled your CPU downclocks in idle mode so the multiplier changes from 9 to 6,disable it if u want to OC

It's not changing it to 6, it changes it to 8.

And Speedstep has been disabled the whole time :/ 

It's a dice roll every time I boot to see if I'll get 8 multiplier or 9...
