Problem #2: Computer randomly shuts off?

[djBon2112]

Alright. If you read my last post, you'll know I was having problems running my CPU at ~2.8 GHz. Well, that's resolved. Sort of.

Now my computer just randomly turns off. It did it last night while testing 2.7 GHz, and it's also doing it now after about 10-12 minutes of Orthos.

It seems like a heat-related shutdown, but my CPU temps never go above about 48 degrees C (MAX), and nothing else in my computer seems unusually hot to the touch after the shutdown.

I'm stumped. Anyone have any ideas?

I'm running the CPU (Opteron 170) at 2.8 GHz, 1.52 volts, on water. Max load temps never excede 48 degrees C, and idle is around 25-29 degrees C.

i have the same problem when i get to 2300mhz it randomly reboots and goes to 1979mhz which is what its set at in my bios.

i think its heat related, even though my amd was at 86F at the time or motherboard related.

Can anyone help us?

this is generally indicative of a bad OC.

Still unstable...

Try running at a much lower OC (just drop the FSB by about 40) and see what happens.

If you ask me, more voltage is needed

That's most likely because Clockgen/other Windows clock generators don't last after reboot. When your computer restarts for any reason, it looks back to the CMOS to find it's clocks, and since whatever changes you made in Windows aren't saved in CMOS, they aren't loaded.

Anywho, this is the OP using my friend's account: My problem isn't my overclock per se. I know it's stable in games and when [H] Folding, and running the OCCT torture test it lasts indefinately. It seems something must be overheating, but I don't know what it is. If anyone has the same motherboard as me (and hell my friend Chilly here ), do you know WHAT parts cause the auto-shutdown when overheating (besides the CPU obviously)?
