Can somebody post here a guide step by step how to overlock my comp ? Specs below. If you need more info about my PC, tell what u need, ill post it here.

Well you certainly don't have the easiest system to work with. What kind of Celeron is it anyway? Is it from the Pentium 4 era, or a laptop?

You will need to see how far your memory will go, and what the default FSB (front side bus) speed is. Usually to OC you simply:

1. Make sure PCI-e speed is locked to 100MHz
2. Lower RAM timings to prevent your RAM from holding you back
3. Raise the FSB gradually. test, if stable raise more, if not maybe raise voltage a notch (CPU voltage, FSB voltage perhaps, Northbridge voltage, all factors coming into play)
If you, for example, have DDR400, while your CPU is running at a 333MHz FSB, the first step would be to try and achieve a 400MHz, so that your RAM and CPU can work together at the same speed, syncronized. It's a great strategy because it will prevent you from having to overclock your memory, which isn't as easy as CPU because of all the little timings.

Anyway, I wish you good luck, since it's not a Core 2 Duo system it may be rather hard letting your stuff run faster than specified. Also don't forget to check up on your temperatures, if they are high already you need to invest in better cooling first.

If this sounds too hard for you, I suggest looking up your motherboard specifications and doing a google on what other people have achieved using it. That way you have some reference material and perhaps a guide on how you shoud do it.

Looking at those specs, I bet it's a Pen-4 era Celeron.

Anyway, I'd suggest that you go into the BIOS and turn your years up as many times as possible. To 2012 to be safe...

That'd already have been a splendid "overclock". :p

But no, really... I think you should leave that system alone. If you need more, consider an upgrade.

Holy crap, this is a joke right, april fools, right? Please update your computer, even the elderly is quicker than that in terms of "Speed". Even though their CPU(Brains) are winding down.
heh i have an even worse pc a pentium 4 @ 1.8GHz ( thats stock )

with 736 mb ram and 32 mb integrated graphic card

Is it your main computer or is it in use? If so, then thats horrible, thats what I am assuming, but if not then thats what I am not talking about, I have a really crappy one, but it's not in use or main.
Yap, I would like to update my computer, but it's easy to say when you have such a good parents. My parents uses this PC only for work that means there is no reason to update, especially for games. Yap they think that a games is waste of time. That's how it is.
even if you overclock a celeron to 4.9ghz, it won't even equal an e8400 at stock. The netburst arch is such fail, overclocking won't do much.
Hope this helps...

You don't really want to overclock that, the Northwood cores suffered from a sudden processor death when overclocking.

Exactly.


I've tried to overclock a Pentium 4 before and while it didn't die, it suffered from extremely high temperatures even with a good cooler.

If at all possible I'd try saving up to get a better computer. You can get a Pentium e5200, a cheap motherboard and 2GB of DDR2-800 RAM for pretty cheap, and just use your existing power supply. (Although you probably would want to upgrade the power supply at some point too).

The e5200 has been known to overclock to 3.5GHz+ easily. Plus Dual Core = :drool:.

$140.

It may be more expensive in your country, but I doubt it is by too much. Do some odd jobs for people, and before you know it you'll have enough.

BigIg is stalking me.

That's the exact same computer I just recently built for my family as a HTPC....stop stalking me BigIg!
Well I've built the same computer before but with a e2200 and a decent GPU. :p
I built a similar one, but the motherboard wasn't the exact same one. It had Silver colored chipset coolers, but I assume the technical differences were minor (all specifications look nearly the same). I instead used a E2160, as the E5x00 wasn't out at the time. I've always loved that motherboard for a budget build. It took the E2160 to at least 3.0GHz (never tried higher, as the FSB:RAM ratio was locked, which is the downside of that board, so even at 3.0GHz with a FSB of 333MHz, where the RAM should have been running it's rated 667MHz, it was running at 800MHz or 900MHz, I forget). Still, a great board for a budget level CPU.

As for the topic in question, that's likely an OEM PC, so overclocking is out of the question.

Not necessarily. I've overclocked a few processors from OEM PCs using Clockgen, but since Clockgen doesn't give you much control I could only OC 200MHz, which doesn't feel like alot more. And that was with an AMD Processor, not a Pentium 4.
Yeah, but I wouldn't overclock through software. The gain he'll get will far outweigh the costs and risks. Northwoods were susceptible to SNDS (Sudden Northwood Death Syndrom), not that the voltage can probably be raised anyway, and if his parents use that computer, and it's probably theirs, I wouldn't advice it. It seems he's asking for games anyway, and while that CPU is really no good, the video card is the bigger bottleneck.
True, I was just saying.. it's possible. :p

It aint worth it believe me, i overclocked Celeron's and it was in vane, you gain very little performance if not close to 0 in some cases. Its not the same as overclocking a Intel Core2, or a AMD, so my advice would also be against it (at least until you get a new PC, after that if you want to experiment you can use the Celeron as a test subject :lol: )
A e 7200 is dirt cheap nowadays
