Overclocking Pentium 4 2.4

[GimpyFuzznut]

Can someone point me towards some information about overclocking a Pentium 4 2.4 processor? Now, I understand that there are two versions of this chip - one which isn't very overclockable and one which can reach 3.0 easily. I bought this CPU with a Dell system and now have it in a nice ASUS P4800SE board with a Zalmann cooler on it. This chip runs at 533 FSB and does not have HT. Last time I checked in the BIOS, the settings for the CPU were locked but the ASUS motherboard does have some options like 5%, 10%, etc overclocking. Anyone want to help me out or is this the chip that cannot overclock?

Forgot that I had SiSoftware Sandra installed. My CPU information is...

Overclocking that cpu should be simple. The ASUS P4800 series have all sorts of adjustments and tweaks you can do. I prefer to do the manual overclock by fiddling with the FSB instead of the 5%, 10%, etc, stuff. You can also adjust the voltage in the bios quite easily.

You will definitely be able to overclock that cpu, the real question is how much.

I've got a similar chip that I am going to try overclocking. It's a P4 2.26 GHz Northwood with 533 MHz FSB. I bought an Epox motherboard to OC it with. Let me know how far you get.

Hop the FSB to 166MHz and sees if it boots. Then you get 3GHz.

Not that simple. You'll need some flexible ram. And the divider options on a 533 MHz FSB processor are limited.

on an asus boards you can use their % Overclocks or if you select manual instead it will open up a lot more options. PCI/AGP freq. lock, FSB clock, etc. Up the FSB incrementally and run prime tests. depending on your memory, you may need to run a divider. if you are running pc3200 you shouldn't need the divider though.

The best one to buy (if they can even be found anymore) is SL6Z3. I had mine running at 275 fsb!

Very nice. Sold it for a quick $.

Ive been using a 3.2E ever since.

If he already has PC2700 or PC3200 ram..then it is that easy..

So true. I upped my old northwood from 2.66B/533 to 3.32B/664 by simply raising FSB. I had DDR333 ram, so ram was not an issue. If memory served me right, I did not have to raise voltage. Achieving 25%OC in an hour, I was quite happy.
