ASUS A8S-X motherboard.

I've searched the manual, PDF's and ASUS's website and cannot find
this info.

So, does it contain something similar to COP or any other overheat
protection for the CPU?

The CPU is an AMD 64 3200+ Venice Socket 939 if that helps.

Thank you.

Did you look in the bios menu? There is often a user
adjustable setting there.

The processor has built-in thermal protection.

My bios has no such features/selections, I've checked a dozen times
till I'm sick of looking at the bios.

So you say this:If the temp goes too high, the cpu shuts down even if
the motherboard has no such settings? It's a function of the CPU and
NOT the motherbaord?

Do I have it correct?

It is not in the BIOS. It is a feature of the processor. If the
processor goes over a temperature specifically defined for that
processor, the THERMTRIP signal is asserted. It connects to the
PS_ON# logic tree, and should shut off the motherboard immediately.

On previous boards, a marketing term was applied to this (COP),
because a chip was added (adds expense to build). With the newer
processors, the processor already has the logic signal for
the protection function. It will still cost a couple pennies, but
is not really such a big feature, as to have a name any more.

Still, you can ask tech support, whether it is hooked up for certain.
I don't see an easy way to verify it, and it is not listed anywhere
on the Asus FAQ page for your board.

THANKS

However would you go with it being RARE for the board not to support
THERMTRIP feature responses?
