How to Overclock the Pentium e2180 CPU
Be careful when overclocking your CPU. (cpu image by aldan from

Intel's e2180 is a dual-core processor in its "budget" line of Core 2 Duo processors. Running the Intel Allendale core at 2 GHz, the e2180 was highly regarded in overclocking circles for its ability to achieve high clock speeds compared to its low price. Overclocking the e2180 is a matter of increasing the Front Side Bus speed of your motherboard in relation to the e2180's CPU multiplier. Overclocking is inherently dangerous, as you're pushing your CPU beyond Intel's suggested specifications, so take extreme caution when proceeding.

Skill level:


    Setting the Overclock

  1. 1

    Reboot the computer and enter the BIOS. This is usually done by pressing "Delete" at the power-on self-test (POST) screen as the computer starts, but check your owner's manual for specifics.

  2. 2

    Locate the "Advanced Settings" or "Frequency Settings" option and select it with the "Enter" key.

  3. 3

    Under the Frontside Bus (FSB) settings tab, increase the FSB setting from 200MHz to 205MHz. Press "F10" to save the settings to the motherboard and reboot the computer.

  4. 4

    Verify that the computer boots properly and stably into Windows. Reboot again and re-enter the BIOS. Continue increasing the FSB by 3 to 5MHz and rebooting until the computer no longer boots into Windows properly.

  5. 5

    Reduce the FSB setting by 10 to 15MHz after the computer no longer boots properly into Windows. Restart and allow the computer to run for a few minutes to make sure everything is operating properly.

    Test the Overclock

  1. 1

    Visit the downloads page for Prime95 (see Resources) and download the program file to your desktop.

  2. 2

    Double-click the newly downloaded program file to start the installation process. Follow the prompts and select the "Just Torture Testing" option.

  3. 3

    Choose the "Blend" test option and allow the program to run for at least 12 hours, but 24 hours is ideal. Periodically check in on the test window to see if the testing has failed. If it has, reboot the computer back into the BIOS and reduce the FSB by 3 to 5MHz.

  4. 4

    Continue the testing/rebooting process until you can successfully run a Prime95 torture test for at least 12 hours. At this point, your overclock is considered "Prime Stable" and you can resume using your computer normally.

Tips and warnings

  • You'll need to have proper system cooling to achieve the highest possible overclock.
  • Overclocking your CPU often voids your warranty, so consult your owner's guide beforehand.
  • Improper overclocking can result in irreparable damage to your CPU, so take extreme caution when overclocking.
