My cpu model is wrong

[sagi_strauss]

Hey, I had win xp, with amd 2600, 512ram
now, after installing sp1, suddely the bios says the model of amd is 2000, and windows sure he is 2000, and uses only 1600mhz!
How could I fix it and make it use all the cpu?
Thanks for all responders ;-)

It looks like the system bus is set to 133mhz...if you have the 333mhz version of the CPU, go into your BIOS and set it to 166mhz, and check your manual for a jumper to set the FSB also.+
