Overclocking describes a process by which computer CPUs (Central Processing Units) are sped up past the default factory limits. Overclocking a CPU such as the Intel Core 2 Quad Q6600 greatly increases the speed of the host computer and allows the computer to perform more tasks, particularly CPU heavy tasks like games. Overclocked CPUs generate extra heat and strain on the system, which are the main deterrents to overclocking. Some older computer models cannot handle the excess heat and therefore refuse to boot when overclocking settings are applied.

Skill level:


  1. 1

    Restart or power on the system holding the Intel Core 2 Quad Q6600 processor. Hold the appropriate Function key during boot to enter the boot menu. Typically, the correct key is F11.

  2. 2

    Select the "BIOS Feature Setup" option and press enter. Select the "External Bus" option and hit enter. Modify the numerical value in the "External Bus" field to the next highest value above the default. This setting influences the speed of the Intel Core 2 Quad Q6600's front bus.

  3. 3

    Locate the "CPU Core" field and select the "Multiplier" option. Increase the numerical value in the "Multiplier" field by 1. This determines the Intel Core 2 Quad Q6600's processing frequency. Exit to the main boot menu.

  4. 4

    Press "Save and Exit." The computer will finish booting and the Intel Core 2 Quad Q6600 is now overclocked.

Tips and warnings

  • If you do not want the overclocking to be permanent, write down the default values in the "External Bus" and "Multiplier" fields so that you may restore them if the need arises.
  • Be sure your CPU has a cooling system that can sufficiently dissipate the extra heat generated by overclocking the processor.
