ATI stalwarts have AMD to thank in recent years for stepping up factory support for overclocking virtually every aspect of system operation. The AMD OverDrive utility not only replicates the OverDrive clocking controls built into Catalyst drivers, it also provides a full range of BIOS style CPU speed, voltage, and system controls unified in a tabbed window. Nice touches include fan controls, a simple benchmark, and a burn-in stability test. OverDrive is also the quickest and easiest way to disable Cool and Quiet downclocking technology when you're looking for consistent performance or high clockspeed stability. If you're running an AMD rig, this one-stop application is a must for system-tuning.
