How to Overclock the Asus P5Q3 Motherboard

The Asus P5Q3 motherboard from ASUSTeK Computers is designed on the Intel P45 motherboard architecture and supports both Core 2 Duo and Core 2 Quad CPUs. Because both of these processors use the same basic structure, overclocking either of them on the Asus P5Q3 board is an easy and simple task that requires users to know only both basic arithmetic and how to enter their PC's BIOS.

Skill level:


  1. 1

    Power down your computer, then turn it back on. You can do this either through your Windows Start menu or by physically holding down your power button.

  2. 2

    Press "F10" at the Asus splash screen during boot up to enter your BIOS menu.

  3. 3

    Use the directional arrows on your keyboard to navigate the menu, highlighting the "Advanced" tab. Press "Enter" to go into the submenu.

  4. 4

    Highlight the "CPU Ratio Setting" option and press "Enter" to adjust the setting. This is your computer's multiplier. You can use either the number keys on your keyboard or the arrow keys to manually input a new ratio.

  5. 5

    Press "Esc" to back out of the settings, and press it a second and third time to back out of the "Advanced" submenu and your BIOS completely. When prompted, press "Y" to save your settings and restart your PC.

Tips and warnings

  • You can get an estimate of your overall CPU speed by multiplying the ratio by the front-side bus speed.
  • Overclocking hardware increases the heat generated by the hardware. Counter this with more fans on the tower, a larger heat sink on your CPU or, if you intend to push the processor to its limits, liquid cooling.
