Overclocking refers to increasing the number of clock cycles run by a computer's central processing unit (CPU), front side bus (FSB), random access memory (RAM) and graphics processing unit (GPU). Clock cycles are measured in hertz (Hz), which is the number of cycles per second. If a CPU is designed to function at 1Ghz (one billion clock cycles per second), to overclock it would increase it beyond 1Ghz to something like 1.2Ghz. Using software to overclock a Dell computer may void your warranty and/or cause other harmful effects. Follow this advice at your own risk.

Download ClockGen to the computer (see Resources). Run ClockGen and click the "PLL Setup" button. This will adjust the Phase-locked loop chip on the motherboard of the computer.
Click the "Read Clocks" button and you should see some letters and numbers in a grid in the bottom of the window. Click on the drop-down list at the top of the window. These are the PLL chips supported by ClockGen.
Try the first PLL in each family -- the families all start with the same letters. Click "Read Clocks," then click on the main ClockGen window and select "Clocks." If you have a working PLL selected, you should see clock speeds for the different values. Test the different PLL families to see which gives you the best results.
Gradually increase the clock speed and test the results. If you increase the clock speed too much, you can make the computer unstable. The goal is to increase the clock speed enough to gain performance but not so much that the computer becomes unstable. Take it slowly and test each setting before you move on to the next setting.
Tips and warnings
- Do not enable "Apply Current Settings At Startup" in the "Options" until you have found a stable configuration, otherwise it may be difficult to disable an unstable setting.
- This may not work on your system. If your PLL is not supported, you may have limited or no overclocking functionality.
- This may damage the computer and/or void the warranty. Use this software at your own risk. Back up any important data before proceeding.
