With all Core2Duo and Xeon cpus, the typical way to overclock them is to increase the front side bus speed. In order to do that, you have to have a motherboard and BIOS that lets you set this manually. Most Dell machines do not have this functionality, but here's a thread where someone asks that question: http://www.xtremesystems.org/forums/showthread.php?t=182861
