How to Increase Performance of an Intel Pentium 4 Processor


At the time of its release, the P4 series was praised for its durability and overclocking potential. With modern cooling systems supporting a P4, you can push the default clock speeds of a P4 far beyond that of its factory settings.

Things You'll Need

  • Pentium 4 with at least an 800 front side bus (FSB)
  • Restart your computer.

  • Quickly scan the flash screen (the first screen your computer displays after it's turned on) for the key needed to access the BIOS. It's generally the "Delete" key, but it could be different in your case. Press this key as soon as possible.

  • Use the arrow keys on your keyboard to find the "FSB Frequency" option (your BIOS may refer to it as "CPU host frequency"). Select that option and press the "Enter" key. Set the "FSB Frequency" one level higher than it is by default. Save the changes.

  • Look for "CPU Voltage." Set the "CPU Voltage" one level higher than it is by default. Doing this will increase the odds of maintaining stability in your processor. It can also fry your processor. Do not take it up anymore than one level. Save the changes.

  • Save the BIOS settings and exit. Your computer will finish booting and take you to Windows.

  • Run various application on your machine to test stability. Games, streaming video, movies--anything that will put some strain on your machine. If you don't encounter any large issues (such as lockups), you have successfully overclocked your machine.
