Would overclocking my 2.22 ghz quad core to 3ghz do it any harm? Because with an AMD utility it won't let me overclock it more than 2.5. Is it a good idea?

Unless you have some pressing need, don't overclock. It's a bad idea as components are rarely that long lived anyhow nowadays...

No.

If you are to overclock your processor, you must do it in BIOS, not by using an application.

Why? You get more control over what the processor will do, and you are able to overclock it more than the utility will allow.

Overclocking in general will make your warranty go out, so if you fry the cpu you'll have to buy a new one.

I recommend going to your motherboard manufactures forum and search for overclocking tips here. Most likely, someone who has the same processor as you have asked a question of what values to set so that it will run as stable as possible.

However, note that not all cpu's are identical, even though they are the same model. So if his cpu was able to overclock to 3ghz, it doesn't necessarily means that your will be able to as well.

I was considering the same thing last year, and when I tried it I nearly killed my PC. Just live with what you have, and save up for an upgrade.

Also, going from 2.2 to 3 is a big jump. Make sure you have really nice cooling.

Yeah, that's the sort of response I was expecting.

It's just that I have a HD 4870, it's an absolute monster of a crad, and I read somewhere that it will only run at it's ideal with a minimum of a 3ghz CPU. One of my friends said they could run Crysis at a good speed at very high, they have exactly the same rig as mine but with a 3ghz CPU. I can run Crysis on very high but I get large slowdowns in scenes with a lot of pressure. So I guess I'll need to save up for a 3ghz.

every cpu i have had i overclocked it as far as it will go ,just make sure there is sufficient cooling and do a stress test to make sure it doesn`t crash , as far as i`m concerned it doesn`t make it last any less as long as u don`t burn it out .

Just take it up in steps and do the burn test .

Aye, me too. I took my intel c2d from 2.2ghz to 3.2ghz

I take my Celeron 630 up to 900 when I play Flatout, otherwise it stays 630. My Athlon 1.8, however, is permanently underclocked to 1.4 in a vague attempt to make it run cold.

Hmm...

Well, what's the ideal temperature for a CPU?

My AMD Phenom quad core idles at 35 celsius most of the time, and runs very quite too.

Overclocking it to 2.5ghz brings it's temperature up to 38 celcius.

So how come, if that's still a very low temperature, my rig freezes when I overclock it any more?

There's more to it than just temp. At that temp, you can safely increase the voltage which should make it more stable. It could also be an unstable memory clock rate.

Okay, thanks for the tip.

Can you tell me where I can find how much voltage is being used throughout the system?

Your bios will tell you, usually under "computer health".

Hmmmm... if something goes wrong, do we take it to the computer doctor? He writes it a little computer prescription and it gets better?
