AMD OverDrive™ application interface

ACC Link Using the AMD SB750

AMD OverDriveTM is a powerful tool with

numerous features and options which
includes clock frequency adjustments, clock
multiplier settings, voltage tuning and memory
timings.

Advanced Clock Calibration is a performance

accelerating feature. This feature is available
with the AMD 790GX platform and can enable
a greater performance turing margin for the
AMD PhenomTM Black Edition CPUs.

The diagram shows the configuration that
enables Advanced Clock Calibration on the
AMD 790GX platform. The below chart visually
describles the benefit of this feature.
