How to Use Overdrive in the AMD Catalyst Control Center

Save

AMD OverDrive in Catalyst Control Center offers you greater control over the operation of your video card. You can overclock, or boost the speed of, your graphics chip and its integrated memory, increase the voltage of the video card to stabilize overclocking or maximize the fan speed to prevent overheating. Increasing the clock speed or voltage of your graphics processing unit too much, however, could potentially damage the hardware, so make only minor or incremental changes to the GPU.

  • Right-click an unoccupied space on the desktop, and then choose "Catalyst Control Center" from the context menu.

  • Click "Performance," click "AMD OverDrive" and then check "Enable Graphics OverDrive."

  • Drag the slider for "High Performance GPU Clock Settings" or "High Performance Memory Clock Settings" to the right to increase the frequency. Avoid adjusting the clock speeds for either component by more than 10 to 20 MHz at a time.

  • Drag the slider for "Power Control Settings" one tick to the right. Depending on your configuration, CCC might prevent you from increasing the voltage altogether.

  • Select "Enable Manual Fan Control," and then drag the slider to the preferred operating speed. You shouldn't need to adjust the fan controls unless you notice your system runs hot after overclocking your card.

  • Click "Apply" to save your changes. Use your computer as normal for at least an hour. If your PC remains stable even when running graphics-intensive software like games, or 3D or Blu-Ray media, you can overclock the GPU and RAM even further in increments of 10 to 20 MHz.

Tips & Warnings

  • If your PC crashes, restarts without warning or shows any other signs of instability, revert your graphics settings to the defaults. Go to the AMD OverDrive screen in CCC and uncheck "Enable Graphics OverDrive."
  • Depending on your video card, CCC might not display all of the options described above.
  • Forcing the GPU fans to constantly operate at a select speed could damage or reduce the shelf life of the fans.
