I have to disagree here, there are several motherboards models from differant manufactues that won't support the Thoroughbred version of an XP and I personally had problems with an MSI 6380 Via KT266a
chipset motherboard that only supports Palomino.
Best check the motherboards website.
True Thorouhbred runs cooler compared to Palomino at any given CPU speed but they perform the same.
Also AMD did send out a sevice bulletin about the use of copper based or all copper heatsinks on the Thoroughbred core due to it's reduced core size and the better heat transfer characteristics of copper or similar materials, although contrary to this Thoroughbred retail CPU's come with an all Aluminium scrived design heatsink.
