hmmmm maybe you have some kind of difference in the system because from what i have been seeing mostly everyone has been having this issue on xp because of the way xp handles the clocks and the threads. really it should be easily fixed with an amd driver because i don't believe xp has the ability to change the clocks based on load while vista does. and the amd driver hasn't changed in awhile.
