i have a celeron II 566 @118fsb runnning at 1004 but its not very stable (dont know why yet). the voltage is at 1.95 but i want to go higher. most people i hear of are running theirs at 2.0 or 2.05 volt. i try to set it to 2.0 and it wont even boot into win2k. any ideas?

As I'm sure you already know - more voltage = more heat. What kind of cooler are you using and what are your temps at idle and under load?

the better the cooler, the better the heat dissipation. So if you don't have a great cooler, get a better one and you should be able to get there.

homemade water cooled 80 peltier system. mbm5 says idle is around
-45F under load around -5F to 0F.

Damn, that friggin' thing is frozen! You'd need Mil Spec chip to operate properly at -45F.

what's a Mil Spec chip? is my proc too cold?

From MIL-HDBK-179A:

Commercial IC Grade; 0 to +70C (Consumer Grade)
Mil Spec Grade; -40 to +85C

At -45F you're at -42.7C, which is even below the required capability for a military specification IC. These ICs are specially packaged and tested for operation installed in the fuselages of aircraft without any environmental protection. All the ICs in a home computer, including the CPU, are designed to commercial specifications.

That's all I was saying.

I have always been curious to know where to get handy information like this... and why should I trust such a statement? I guess, in short, I need to ask -- what's your source?

im no electrition but from what i know the higher the voltage, the lower the current. now we all know that the current is what produces the heat in electrical appliances. so i dont know why the pc bitches when we set a higher voltage, when were are reducing the current and making it cooler.
