1. Power down your comp.
2. Open the case.
3. Look for the PLL on your mainboard. Tips for finding the PLL can be found here (http://www.podien.de/FSB.HTM).
4. Once you've found the PLL, write down the make and model number, then close up your case.
5. Power back up.
6. Download CPUFSB (http://www.podien.onlinehome.de/CPUFSB.HTM).
7. Install the program.
8. You MUST reboot the system after installing.
9. Run the program.
10. On the left you should see 4 drop-down boxes.
11. For the Mainboard Manufacturer, select Abit. (As far as I know, most, if not all current Dell mobos are stripped down versions of Abit's.)
12. For the Mainboard Type, leave it at None.
13. For the PLL manufacturer, select the maker of the PLL that you found in step 3.
14. For PLL Type select the model number that was stamped on the PLL.
15. Hit the "Save" button to save the settings.

NOTE: If your PLL has the "fine tuning" option, use it instead of the below "Frequency to Set" option. It allows you to adjust in smaller increments and typically can give you a slightly higher overclock. It follows essentially the same steps, just click the "Fine Tuning" button first.

16. Under the "Frequency to Set" heading, click the up button a couple of times until you are at the desired FSB you wish to set. (Obviously, start with a small OC and work your way up until the system becomes unstable or freezes.)
17. Hit the "Set Frequency" button.
18. Hit the "OK" button.
19. If the FSB is too high the system will freeze immediately. Reboot and try again with a lower FSB.
20. Click the "Save button again once you have reached a stable overclock. This will retain the FSB setting.
20. Once you have acheived a stable overclock, you can click the "Exit CPUFSB immediately after call..." checkbox and place a shortcut to CPUFSB in the Startup folder. This will start CPUFSB on Windows startup, and then immediately exit once the FSB has been set. Alternatively, if you only want to overclock at certain times, don't do this.

DISCLAIMER: I am not saying that this will work for EVERY Dell. Some adjustment of the settings may be needed (ie: mobo). However, it can be done
