"Here's a little known secret for you to chew on: that triple-core AMD Phenom II X3 you purchased actually has four cores. The last one's just locked down for pricing purposes. A Korean site has disclosed information that enables owners of select motherboards to unlock that fourth core, and apparently, all you need is a Biostar mobo and / or a BIOS that has an option labeled Advanced Clock Calibration. When said selection is flipped to \"Auto,\" the fourth core is loosed from its shackles and able to ever-so-slightly up your frame rates and overall level of excitement. Of course, you're taking a big risk by running a chip in a fashion it was never intended, but what fun is life without a little edge-side living?[Via Slashgear]"^^<http://www.w3.org/2001/XMLSchema#string>
