30 ATI Overdrive 3

ATI Overdrive 3

Use the ATI Overdrive 3 aspect to maximize the performance of the graphics processing unit (GPU) on your graphics card. An on-chip thermal sensor constantly monitors the temperature of the GPU allowing the maximum clock speed to be maintained while avoiding overheating. If the GPU gets too hot, the ATI Overdrive 3 aspect will automatically decrease the clock speed until a safe temperature is reached. The ATI Overdrive 3 aspect will never reduce the graphics processor speed below the default clock speed.

Use the Automated clock configuration utility to obtain the ATI recommended the ATI Overdrive 3 aspect speeds for the graphics processor clock and video memory clock. Alternatively, manually set these speeds to meet your specific requirements. Finally, the ATI Overdrive 3 aspect can be configured to run when the computer is booted or only when running 3D applications.

•If your computer cannot restart after setting a higher clock speed, press and hold the SHIFT key during system start-up until you hear three beeps. Once your computer has full booted, disable Enable new clock settings at logon.

To access the ATI Overdrive 3 aspect

•Select ATI Overdrive 3 in the Catalyst™ Control Center advanced view.
