There are a number of items that are part of Windows XP activation.

You are allowed to change up to 3 reported items at one time without triggering a product activation event.

Since AMD CPUs do not report an internal serial number to Windows, an AMD CPU is not part of product activation.

If all you change is the CPU itself, there will be no problems with XP.

There is a well detailed article on product activation posted at www.aumha.org

Before changing your CPU, there are a couple of things you should check.

1. What version of BIOS is on your motherboard?

2. Does the version of the BIOS support the new, faster CPU?

3. Is your RAM the correct speed for the front side bus speed requirement of the new CPU?

Most of this information should be available at the motherboard manufactures web site.
