I bought a AMD ATHLON X3 (tri core 3.2ghz) and an Asus M5A78L-M LX which has the core unlocker feature and you need to flip a switch. I was wondering what are the advantages of doing this and the disadvantages?
Disadvantages are that it may not have a stable and functioning 4th core. If you do have a stable 4th core it will raise temperatures and power consumption. If you are using the stock heat sink it may be inadequate for a quad core. Unlocking mine raised load temperatures by about 10C which pushed it close to the recommended max. Of course a aftermarket cooler solves this issue.
