Perfect Heat

[slee_15]

Im thinking of overclocking my celeron 733mhz to 1ghz but before i do it i would like to know what is the critical temp. (like a temp. my CPU should not go over) this would be usefull as it is Summer here in AUS and i would like nothing to go wrong....

Cheers

Hi slee_15 ;)
First of all you have to see wich for your cpu the max temp is on the intel-celeron spec-information sheet...if I well remember it would be about 80°c.
So you have to don t reach a temperature higher than 60-62 °c when your cpu is working at the highest priority.
Some people claim that the max temp must be 45°c...don t know how it would be possible when some tests using a overclocked PIII and a water cooling system have revealed maximum temperatures of about 60°c in full load mode.
Remember that another important factor woul be the core voltage...don t worry to increase it of about 0.3/0.4 points ...in some cases a higher voltage will increase the cpu stability...obiviously you have to cool well your cpu.

For any kind of stability, you wanna stay under 55C, preferably under 45-50C. Some processors can handle 60 but many will just run for awhile and lock up. That 80C shiznit is just an operating temperature... realistically, no processor could run at those temps with any kind of stability.

As far as Vcore goes... check out my sig on my second machine. The default voltage is 1.75V, I am running it at 1.60. It's still OC'd and it'd go higher if it weren't for my stupid PCI graphics card (don't get me started, long story). Back when I had a Celery 600@1026, I ran it at 1.95V... so sometimes it is necessary to add voltage, but not always. Don't increase voltage unless your computer becomes unstable, and if you raise it more than .2V or so, get better cooling.

For overclocker it is critical to stay within 45-50 as raising the vcore becomes dangerous when your at temps near 55 since you can just burn the chip out without proper cooling when raisng the vcore, as that is why people here tell you not to raise the vcore as much without adding special cooling.
