ATI Overdrive 3 
</h2>

<p class="pBody">
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.
</p>

<p class="pBody">
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.
