Vilket OS har du? XP Pro SP2 skall väl klara dual core?
Som
Wernborgdrloop redan påpekade, klarar t.om XP Home av dualcore.

"While Windows XP Home does not support more than one physical processor, there's a lot of confusion about whether or not it supports multiple processor cores in a single physical processor. This is implemented in several ways, of which the most widely used is Intel's Hyper-Threading technology. Also, AMD is currently rolling out a series of 64-bit processors called the X2 dual core series, which features two processor cores per die.
How much of this is supported? The answer is all of it -- in XP Professional, and, surprisingly enough, in XP Home as well. If you install XP Home on a system that has a single processor with dual cores or hyper-threading (what is referred to as two logical processors—XP Home will recognize both of them, and will install the appropriate Hardware Abstraction Layer (HAL) to work with it."
