I was wondering, is it possible to turn off cores on the C2Q Q9000 (the mobile one)?? Or you have to have 4 cores on at all times? And I don't mean turn off on the fly, but rather like a setting you can change pre-boot.
Some BIOS's have the option to disable cores. Another way is Start > MSConfig (or Start > Run > Msconfig is you're on XP). Select the Boot tab, then Advanced options and you can set how many cores you want in there.
