Ok guys kinda newb to CPU troubleshooting, sorry if I screw this up.

I have a P4 2.66Ghz and I noticed the other day that it was only running at 1.6Ghz.

Looking into the BIOS (P4VM800) I find:
133 FSB with 12x muti. [LOCKED]

There are no EIST/speed stepping options.

I upgraded to the latest BIOS - same issue.
Disabled spread spectrum - same issue.
Disabled CPU thermal throttling - same issue.

Any ideas? Any way to get that multi up to 20 where it should be?

My mobo manual

Thanks guys

Hmm, are you sure it isn't a mobile P4? The chip looks to be fully supported by your board. 533mhz FSB northwoods don't have speedstep, so either it's a mobile, it's not actualy a 2.66ghz(that wouldn't make sense either, there is no 1.6ghz chip for 533mhz FSB), or there is something wrong with the motherboard or cpu.

Mobile P4 chips dont have heatspreaders. So if your chip has a heatspreader, it's not a mobile.
