Help on overclocking

Hi all, I want to overclock my old P4 2.4GHz (Prescott) CPU. I have the stock cooler, how much can I expect to get from it?

My main question is, I know I also need to raise the core voltage, but how much exactly? I don't want to burn anything...

Thx for any help, J.M.
 
I wouldn't expect too much out of the stock cooler. Before you try ocing, you'll want to know your idle and load temps

Looking around a bit, seems that the max safe temp for prescotts is around 68-69*C

You don't necessarily need to raise your vcore right away either.

this guide should also help

thanks, I just tried upping the "CPU frequency" to 140mhz (from 133) and ran a few mins of 3Dmark, the temp went to some 49C. I guess this is good:cool: Also noticed that with the fsb also RAM freq. increases, should I be worried about this?
 
1st off read the guide.

Then another guide.

Then a few more.

They're there for a reason.

Next up, what's your motherboard?

I inputted my comp. specs when I was creating profile, it's MSI PT880 (neo).

I was on 144 fsb and when running 3dmark the comp suddenly restarted by itself:rolleyes: :mad: the CPU was only 51C or so! I don't know what made it to do that, probably it was a component other than the CPU, memory maybe?
 
It can be a few things:

1. Your mobo can't handle that fsb

2. Your cpu isn't getting enough juice

3: Your ram can't run at the speed you're trying to make it run at

for #1: if your mobo supports it, you may be able to up the voltage to the northbridge otherwise you'll have to lower the fsb

for #2: up the vcore a little until it's stable (if you can). Keep in mind that more voltage = more heat

for #3: up the ram voltage and/or loosen the timings. If that doesn't work then you'll have to run a memory divider

A few minutes doesn't really give you a good picture of the load temp, try running memtest, prime95 or OCCT for a while (about half an hour)

running memtest will also tell you how your memory is coping with your oc
 
It was the memory. I've switched it from default 400Mhz to def. 330Mhz and it doesn't crash any more. This must be one crappy memory if it can't stand 10% frequency increase :mad:
 
I noticed one really odd thing- as something heats up (looping one test in 3dmark), the FPS goes down (by some 5 or so %). Is this normal? I don't think so and I have no idea what could be causing it. Any advices?
