CPU running at half speed - please help

I am putting an old P4 together. CPU reads at 1.3 GHz instead of 2.66 GHz. I have done some searching and found about the multiplier being wrong, but I can figure out how to change it. I have a jumperless mobo and can't find the right setting in the BIOS.
BIOS has FSB at 400 and RAM at 266. Should be 533 and 333. Option for 333 doesn't show up, just 266 and auto. I ran speed test and processor is truely running at 1.3 GHz.

Please help me with some suggestions on how to fix this. Mobo is Intel D845GEBV2. Thanks

what CPU and RAM do you have ? have you checked if they support higher clock than FSB 400 and DRR 266 ?

Normally this caused from incorrect settings within the bios. The FSB should be manually set and then this will change your processor speed.

You may want to try and search for bios updates aswell.
