The Intel Core i5 is a next generation processor designed and manufactured by Intel. The i5 can be used in both desktop and laptop PCs and stands near the top of Intel's line-up, with only the Core i7 ahead of it. While the processor is available in several variants, including both dual-core and quad-core designs, all i5 CPUs feature an advanced architecture -- based on a 45 nanometre lithography process -- that not only allows a huge number of transistors to be packed onto a relatively small size die, but also brings down operating temperatures while delivering solid performance for demanding users running processor-intensive applications.

Skill level:


  1. 1

    Turn on your PC and press the "Delete"or "F2" key immediately upon bootup.

  2. 2

    Navigate through your system BIOS (binary input output system) using the arrow keys until you locate the "System Performance" menu or "Overclocking" on some newer systems, then press "Enter."

  3. 3

    Highlight the "Expert User" option (if it exists) to allow access to the system speed settings.

  4. 4

    Scroll down until you see "FSB Frequency" and press "Enter." Because most CPUs are multiplier locked this is the only option available for overclocking.

  5. 5

    Increase the FSB (front-side bus) speed by no more than 5-10 mhz. Press "Escape," then "F10" and click "Yes." This will save settings, restart your computer and boot into Windows. Test the system stability by running several of your applications. If the computer responds normally, you can try another slight increase in the FSB speed. Keep in mind a 5 mhz FSB increase, may yield a 75 mhz CPU clock increase due to the high multipliers used.

Tips and warnings

  • A high quality aftermarket cooler is recommended to help ensure system stability when overclocking.
  • Overclocking may void your warranty and damage your CPU, proceed with caution.
