Yes. But just for kicks, what mobo is it that you have and what CCPU? I am guessing its a Intel Core 2 with the 1333FSB.
Now even though it may not have suuport its truly dependant on your chipset. Most of the time only the P35 and up will support all the Core 2 Duos and Quads but some of the older mobos (Asus has a P965 that supports the 45nm Penryn chips) will support them.
