Overclocking a computer’s processor or memory causes it to go faster than its factory rated speed. A processor rated at 2.4GHz might be overclocked to 2.5GHz or 2.6GHz, while memory rated at 200MHZ might be pushed to 220MHz or higher. The extra speed results in more work being done by the processor and, or memory in a given time, increasing the overall computing performance of the PC. This article will guide you through each step of overclocking your CPU for faster processing speeds which will increase clock speed of your computer.
You will need:
- Needle-nose pliers
- Computer fans
- Heat sink compound
- Screwdriver set
- Computer power supplies
- Backup drives
- Assemble all the necessary tools and materials listed.
- Verify whether your motherboard can be adjusted in the BIOS setup, with jumpers or not at all.
- Find out clock speed limitations of the motherboard.
- Run all diagnostic applications you have and fix all system problems.
- Create a complete backup of your system, documents and applications you don’t have on CD-ROM. Do not overwrite these copies.
- If you have a BIOS adjustable motherboard, make changes according to your motherboard manual, and skip to Step 15.
- Shut down computer.
- Leave computer plugged into surge protector.
- Disconnects all peripherals from computer.
- Remove the chassis cover.
- Ground yourself to computer with any professional grounding equipment you have. Otherwise, ground yourself by touching a metal part of the chassis.
- If your motherboard has adjustable jumpers, locate the jumpers that control the CPU speed.
- Use needle-nose pliers to change jumper settings. Move jumpers to positions indicated in your motherboard manual for the clock speed you want. Check the internet for recommendations.
- Install a CPU heat sink compound, and a speciality cooling fan, if appropriate and possible.
- Put system back together, and reboot.
- If computer does not boot, and CPU still works, try lowering the clock speed. If that doesn’t work, restore the original configuration.
- Check all functions, and run a CPU-intensive program.
Tips and warnings
- CPUs have rated maximum speeds. Exceeding the maximum speed is far more likely to cause problems than more conservative adjustments.
- Overclocking an Intel processor explicitly voids its warranty. Other manufacturers have similar exclusions. Intel prevents overclocking of some CPUs by disabling higher multiplier settings.
- Expect a shorter life for an overclocked processor, including the possibility of its immediate failure.
- Prepare to deal with seemingly unrelated problems that can be caused by overclocking: destruction of other internal component, loss of data, system and application crashes, and an inability to boot the system. These problems may occur randomly or materialise well after you have altered your motherboard.
