Overclocking is the process of increasing a computer's default clock frequencies for an added performance boost. To overclock successfully you must have a thorough knowledge of your computer's internal components. Accelerating clock frequencies can be a challenging task if you don't know what you're doing, which could result in permanent heat damage. Overclocking a Sony Vaio laptop safely requires patience and multiple attempts to find the optimum performance boost, while retaining performance stability.

Skill level:
Moderately Challenging

Things you need

  • Prime 95
  • Set FSB 2.3

  1. 1

    Download and extract Set FSB 2.3 -- a free overclocking tool and the only one compatible with the Sony Vaio -- to the computer and run the program (see Resources).

  2. 2

    Click on the "Arrow" icon next the "Clock Generator" field and select the clock generator for the Sony Vaio laptop from the drop-down menu. Click "Get FSB" to confirm your selection.

  3. 3

    Increase the "FSB Frequency" by increments of 10MHz, for example from 200Mhz to 210Mhz. Click the "Set FSB" button to apply the custom configurations.

  4. 4

    Download and install Prime 95, a free overclock testing tool (see Resources). Double-click on "Prime 95.exe" to run the program.

  5. 5

    Click on the "Options" tab on the top of the Prime 95 window and select "Torture Test." Click on the "Start" button to initiate the test and allow it to run for at least 30 minutes. If the computer retains stability and doesn't crash, click on the "Stop" button to stop the test and increase the "FSB Frequency" by another 10MHz in Set FSB.

  6. 6

    Click on the "Start" button in Prime 95 to run the "Torture Test" again and repeat this process until you find the optimum performance boost for the Sony Vaio. If the computer does freeze, restart it and lower the "FSB Frequency" to the last stable level.

Tips and warnings

  • Overclocking is trial and error process that requires multiple attempts to get right. Take your time and have patience to be successful.
  • Don't increase the "FSB Frequency" by a large increment because it could cause a sudden heat flash that could permanently damage the computer's internal components.
