How Do You Overclock a CPU?

To overclock a CPU, install and launch an overclocking utility, increase the CPU speed by 1 degree, restart the computer, check the CPU settings, gradually increase them, then reduce the settings by 2 or 3 degrees. This 45-minute procedure requires an overclocking utility and a CPU performance utility.

  1. Install and launch an overclocking utility

    Install an overclocking utility if your computer does not already have one. Open the program.

  2. Increase the CPU multiplier speed

    From inside the overclocking utility, increase the CPU speed by 1 degree.

  3. Restart the computer

    Reboot the computer. If you do not see any error messages, it is safe to continue overclocking.

  4. Examine the CPU performance

    Open your CPU performance utility, and run a stability test. If your CPU passes the test, increase its speed by one degree, reboot the computer, and run another stability test.

  5. Increase other settings

    After your computer passes the second CPU stability test, examine other CPU variables such as the voltage settings, fan speed and memory timing. Increase one setting, reboot the computer, perform a stability test, and open a graphics-intensive game or another program that taxes your computer. If the machine exhibits increased performance, adjust another CPU setting and repeat the rebooting process. If there is no improvement, undo the setting, and increase another one.

  6. Push the CPU to the brink of instability

    Keep increasing the CPU settings until your system is on the cusp of instability, then reduce them by 2 or 3 degrees. Reboot the computer.
