The BIOS allows for plenty of voltage and frequency modification to satisfy overclockers, and even includes the ability to increase Sideport memory voltage. Those looking to squeeze better energy efficiency and lower temperatures out of their CPUs will be somewhat disappointed as the minimum CPU voltage is -0.30V (1.025V in the case of our X3 720 processor). The fan control options allow you to set the CPU fan's starting voltage, and the temperature range. There are no settings for the other two fan headers.

Editor's Note: The MSI board came from AMD with a BIOS version assured to be the latest and greatest. The Asus board, on the other hand, came from Asus, with a BIOS dated some 3 weeks earlier than the version AMD was offering for the board on its media FTP site. The more recent BIOS version at AMD was not recognized by our board to be compatible with it, and there were no other BIOS options on the Asus web sites.
