All about AMD OverDrive Technology

AMD OverDrive technology is an overclocking feature that lets you customize the performance level of graphics processors and/or CPUs that are installed in your system. The type of settings that are available vary between systems:

  • Settings for overclocking the CPU are available for systems installed with a Black Edition AMD processor.
  • Settings for overclocking the graphics processor are available for systems installed with at least one AMD graphics card that supports GPU overclocking.

If your system supports only one setting type, the settings appear in the AMD OverDrive page.

If your system supports both types of settings, the settings are divided between the CPU OverDrive and Graphics OverDrive pages. Settings for both pages can be enabled and disabled through a master control on the AMD OverDrive page.

Note: Before you can overclock a CPU or graphics processor, you must first review and accept the AMD OverDrive technology license agreement. You should also make sure that you are using high-quality system components to ensure maximum system stability.

Right-click the Control Center system tray icon in the Windows® system tray (taskbar notification area), point to 3D Settings > Force Maximum Performance Clocks, and then select one of the following:

  • Disabled—Allows applications to run at custom 2D GPU and memory clock speeds, if needed.
  • Enabled—Allows all applications to run at 3D clock GPU and memory clock speeds.

Overclocking CPUs

If your system is installed with a Black Edition AMD processor, you can test different CPU performance levels to determine which ones can be used to overclock your CPU. Once performance levels have been determined, you can manually set your CPU to the one that best suits your needs.

A performance level is a combination of the CPU clock speed, core voltage, and multiplier.

When done correctly, overclocking can help you maximize the capabilities and increase the performance of your CPU.

Settings for CPU overclocking can be found in either the AMD OverDrive or CPU OverDrive page. The availability of pages vary depending on the AMD OverDrive™ technology settings that are available for your system.

Finding CPU Performance Levels using Auto-Tune

Before you can overclock a CPU using AMD OverDrive™/CPU OverDrive technology, you must first run Auto-Tune to test and determine which performance levels can be used.

Auto-Tune is a test tool that finds performance levels by gradually increasing the clock speed and core voltage of the CPU and testing for system stability.

If at least one acceptable performance level is found, you can manually set your CPU to any of the levels. If no performance levels are found or if Auto-Tune cannot complete, no overclocking changes are made.

Use the AMD OverDrive or CPU OverDrive page as appropriate to run Auto-Tune. The availability of settings in the page varies depending on results from Auto-Tune.

  1. If your system supports only CPU overclocking, navigate to the AMD OverDrive page using one of the following groups. If your system supports both CPU and graphics overclocking, navigate to the CPU OverDrive page instead:
    • Standard View—Performance > Clock Controls.
    • Advanced View—Performance.

    Alternatively, click the Configure CPU OverDrive link, if available, on the AMD OverDrive page.

  2. Select the Override existing CPU settings check box.Selecting the check box allows you to ignore the CPU settings that are currently used by your system when you run Auto-Tune.
  3. Click Auto-Tune.
  4. In the Testing CPU dialog box that opens, click Start to begin detecting performance levels. If needed, review the warning that appears and click OK to continue.The clock speed and voltage currently being tested are shown in the dialog box, along with the progress of the test and the number of performance levels found.
    Tip: To stop the test, click Stop.
  5. Restart your system.

If Auto-Tune completes and more than one performance level is found, the highest level is shown, and you are prompted to restart your computer. You must restart your system before the performance levels become available for selection on the page.

If Auto-Tune cannot complete or only one performance level is found, a message appears notifying you of the test result, and you are prompted to restart your system. No overclocking changes are made to the CPU.

Enabling/Disabling CPU Performance Levels

Enable the CPU overclocking settings to access the performance levels found through Auto-Tune or disable them to use factory default CPU performance levels.

Note: CPU overclocking settings are available only for systems installed with a Black Edition AMD processor.
