2 general questions re: voltage/heat, and "breaking in" a CPU.

Hello everyone.

As the subject says, I have two questions of more a general nature, rather than specific hardware problems I am having.

1) Which is the limiting factor when overclocking between the voltage setting, and CPU temperature? I realize that they are interrelated, but if I can keep the CPU temp down, can I continue to raise the voltage? Or should I stop at a specific voltage no matter how hot I'm running?

2) Is it true that when overclocking a processor, "breaking it in" for awhile at a lower speed helps it? I've heard some say yes, and some say no. I'm just looking for opinions here.

Thanks for any help anyone can provide for either question. 🙂

Prudent and "cautious" overclocking practice is to add no more than 10% to a CPU's spec Core Voltage. For example, if the processor is designed to run on 1.6v, adding 10% of this value(0.16v in this case) to the Core Voltage gives you 1.76v. Pretty easy formula to remember.

This "10% rule" is broken with abandon by owners of the new small blue "glass" slugs that are today's CPU's. Perhaps the fact that the new CII's/PIIIE's put out only ~75% of the heat that their older copper encased siblings do makes people think that over-volting the crap out of these CPU's is good practice.

The truth is that efficient cooling is more necessary with the 0.18 micron CPU's than it was with the older 0.25 micron processors.

It is your CPU, after all. Happy overclocking!

The "burn-in" process as done by OCer's has no foundation in fact, say the EE's. Nonetheless, it works for some people.
 
I understand. Well, right now I am O/C'ing my Celeron II 533, and running it at 1.85v (VCORE in the BIOS reports 1.82v). If I knew what the spec voltage for the Celeron II was, I guess I'd be able to tell by how much I'm violating the 10% rule. 🙂

So, what is the spec voltage for the Celeron II?
