How to overclock a Dell:

I have a Dell, and I retract all statements that they don't overclock. I now say it is hard to find out how to overclock. However, here is a short guide on how to do it if you have one:


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.majorgeeks.com/download.php?det=420).
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.


So far, I have only managed to overclock by 7% on my p4, but that's with the stock cooler. once I get the kit, I will be able to go much futher :)

happy overclocking :D


I TAKE NO RESPOSIBILITY FOR ANY DAMAGE TO HARDWARE, FINANCE OR OTHERWISE, THAT COMES AS A RESULT OF THIS POST.
Remember, If you overclock, your processor can overheat and break. Use a testing sofware (e.g. OCCT) to make sure the processor is still running properly

Yes, it isn't impossible. Just very very complicated compared to a own built system.

Just a note though, if you are going to make a "guide" or even a mention like this. You need to warn people to keep an eye on temperatures.

Also, do you have any control over what voltage your cpu is getting? How about temps? Does it pass prime95?

If so, great! I know a lot of people who can't get as far as you have. (But probably on different systems).

Also bear in mind that if anyone does try this it probably invalidates any warranty they may have with Dell

And Novatech bear no responsibility for any damage which may be caused by following the above guide!

Forgot to mention! If you have socket775 then your temps will be accurate.

But if you have a socket 478 P4 then the temperatures are actually SOCKET temps. SO keep that in mind.

It's not detectable really, certainly not provable!

You just need to bear in mind that the motherboards used in dell's and similar systems are a long way away from what go into custom builds, they are cheapo and not designed to OC at all!

Also, they might be built with a generic PSU that might be able to cope with the system at stock, but not when overclocked. (I'm stopping adding stuff every other post now, I promise :D).

OK, cheers ppl. The first post now has a disclaimer, and I haven't found a program that tells me what the CPU temp is, so if anyone could help me....
(i've tried speedfan, CPU-Z, CPUcool, OCCT and i think that's it.)

oh, and i forgot about the guide section. should this be moved? I think it is a guide?

Fair play if it works thats great for all dell owners. I searched high and low and never found a way.

Coretemp and Realtemp

nope, don't work :(

have you tried cpuid's hardware monitor or everest to get temps

yeah, didn't work. Might be something to do with the dell mobo. not sure :(
OCCT seems to think I only have 2 temp sensors - one for each HDD

If you cannot find out your cpu temp, then I would suggest returning to stock settings as soon as possible!

When you have done this, I would try the following programs:
-Realtemp
-Coretemp
-PC Wizard
-EVEREST free trial
-Speedfan

Those aren't in any particular order. But you need to know what temp your cpu is at. otherwise you might be killing it.
