The AMD OverDrive 3.1 application was designed to be a utility the provides the ability to maximize the capability, flexibility, and adjustability of the AMD chipset products. It allows user to tune parameters to ensure system stability, optimize performance, and control cooling/acoustic characteristics. AMD's free tweak and overclocking suite is called OverDrive. One of our editors once stated 'AMD OverDrive is the work of the Devil'. And he meant that in the most respectful way. I agree, the software is diabolical, dark evil... very good.
