Computer rebooted during Orthos, find out why?

[quadomatic]

I was testing my overclock of my Phenom II with Orthos, and the computer rebooted about 9 hours in while I was asleep (I looked at the orthos log files and the last successful test had been recorded).

I don't really know why the computer rebooted...I don't know if it blue screened, or if something got too hot and the computer rebooted because of some failsafe setting (it can't have been the CPU since my unlock disables temperature monitors...).

Any ideas on how I can figure out the cause, or if some log file was made on reboot?

If it BSODed, you should have a memory.dmp file which you can analyze:

You can also turn off auto-reboot on BSOD in the advanced system properties. Makes it easier to determine why the computer rebooted.

Doesn't look like it BSOD'ed.

The memory.dmp file says it was modified yesterday at 3PM. It was from an earlier BSOD, so it doesn't look like it BSOD'ed.

I guess it's possible that it's the PSU, but I'm not sure how likely that is. The computer still turns on just fine, and I'm using it right now at the overclock I was testing.

If it didn't BSOD, then it's likely not a memory issue, right?

a hard reboot with no BSOD can be caused by the CPU.

a shutdown however is more indicative of a thermal issue. i would say that you werent stable at that frequency.

i would back off a little and try again tonight.

I ran orthos once before this at a slightly lower voltage, and 9 hours in, one core had a fatal error and stopped its test, but the other 3 were still going (for 14 hours IIRC).

I bumped voltage .25V more after that, so I guess it's possible that the extra heat made it give out.

Are you on a UPS? It's possible you just had a brief power interruption; it doesn't take much.

No, I'm not on a UPS.

If it was a brief power interruption, wouldn't it have shut down, not reboot?

Also, nothing else (like my alarm clock) plugged into the same outlet was affected.

May be the OS updated and restarted while you were asleep.

My OS isn't set to do that.

Aren't you monitoring temps?

What kind of cooling does your motherboard have? Mosfets can get extremely hot, and cause instability.

I can't monitor CPU temps, since the quad core unlock disables temperature monitoring for the CPU.

My CPU has a Freezer 7 Pro, but my motherboard doesn't really have any cooling. The northbridge chipset has a relatively large heatsink, but that's about it.

UPDATE: Apparently a couple people with the same motherboard as me have had problems because of a lack of MOSFET cooling. I'll probably pick up these:

I'll have to count how many MOSFETs my motherboard has though...I think I'll need 3 packs

Same heatsinks I used on mine. I used 2 packs, with a few left over. Gigabyte 785g USH.

I have an unlocked quad. Using a program like Everest or AMD Overdrive, you can still get CPU and motherboards temps, but not core temps. I don't consider the readings Gospel, but at least I have a ballpark figure and a frame of reference.

AMD Overdrive doesn't give me Core temps. It does give readings TMPIN1, TMPIN2, TMPIN3, and TMPIN4 (which is -297.4 degrees Celsius...). Are those TMPIN readings for the CPU?

UPDATE: found that it's "TMPIN1 = CPU die temp. TMPIN2 = Chipset temp. TMPIN3 = System/Motherboard temp"
