Overclocking your computer's processor speed can be a risky endeavour. When it runs past its advertised abilities, you run the risk of overheating your machine. However, with the proper technique, your machine may safely outperform the maximum power and speed at which it ran previously. Dell's XPS 420 computers use a Quad Core Q6600 processor, which is built to run at 2.4 gigahertz, or GHz. By overclocking your device, you may see speeds up to 3.0 GHz.

Skill level:

Things you need

  • Dell XPS 420 Quad Core Q6600 computer
  • Phillips head screwdriver
  • Electrical tape
  • Utility knife

  1. 1

    Open the case of your computer by unscrewing the screws from the side panel and lifting it outward.

  2. 2

    Locate the fan inside the computer and remove the four screws on each of its corners.

  3. 3

    Pull the fan from the board it is attached to very carefully.

  4. 4

    Remove the processor chip by lightly prying the metal case away from its slot.

  5. 5

    Cut two very small strips of electrical tape, roughly 1/8 of an inch wide and 1/4 of an inch long.

  6. 6

    Place them over two of the metal circles on the processor. When examining the processor, there will be a ridge on either side. Orient the processor chip so these ridges are to the left and right sides of the processor and that they are below centre of the chip. On the right side, count seven rows up. Cover the metal circle to the far right of the chip, directly above the ridged area, with the tape and flatten any excess over the side so it does not cover any of the other metal contact areas. Do the same thing for the metal circle exactly two rows up.

  7. 7

    Replace the processor, metal casing and fan inside the computer as you found them.

  8. 8

    Replace the outer cover of your PC.

Tips and warnings

  • When overclocking your personal computer, you run the risk of overheating your machine. Make sure your computer is well-ventilated. If it gets very hot, turn it off for a while and let it cool down; otherwise, your system may get damaged. When encountering the computer's fan, be sure to clean off any dust that may have built up inside the device. This will ensure a more efficient cooling mechanism.
