I have changed my P4 from a 2.8G to a 3.4G. When the computer restarts, it says
"Alert! The processor is not supported on this system, and will run at a reduced speed."
The computer runs better than before with the L2 cache now being doubled I would guess.
It still does not recognize the CPU as 3.4G. It thinks it is 2.8G. Here is the info on my system.
I have CPUID, Everest and Belarc for any other information that is needed.
Just let me know.

Thank you for your time in helping me with this.
