Instability under Windows 8

Hello,
I wanted to post here to see if anyone else has been having problems under Windows 8 with ATI cards.
I have a Win 8 machine that was happily doing BRP-4 with two nVidia 650ti's. I got a good deal on a pair of 7970's and upgraded the machine as an intermediate step to making a rig that could properly feed the ATIs (the one they are in now can't take full advantage of the cards yet because of the processor and PCI-E bandwidth).
I'm running CCC 13.1, and have the latest BIOS on my motherboard and the latest Windows updates. The card temperatures hover around 60-63C, and CPU temperature is negligible. The cards will crunch happily for hours, and then I'll experience one of the following:
- A whole series of computation errors, or
- The graphics driver will crash, or
- Windows 8 will crash and restart (this is the most common).
Once I get a crash, I tend to get several in the span of a few minutes, and then everything settles down for hours. But the next morning when I get up, I can see that the system crashed again during the night.
The cards have a small factory overclock, but everything else is stock. I have never seen any indication that the problem is heat-related.
As I type this, I've been running a Furmark burn-in test on the cards, and they've been doing an OpenGL render at 100% GPU with temperatures at 74C and 90% fan speed for an hour now, no problems whatsoever.
Any input?

That's a good idea; I'll try that with one card, then the other. I'm at 3 1/2 hours on the stress test now with no problems.

In my windows 8 laptop I can't do GPU units but for some time it was crashing doing the CPU units. I backed the processor time off and it's been running the past 12 days with out a crash/restart. I really think it's heat related for me and it could be heat issue for you as well.

I might also see if I can underclock the boards a little, or one of them if I can isolate the problem it to one board. The 74C was a stress test running the cards at absolute maximum rendering capacity; Einstein runs at 60.

After a little research, I found some people complaining that ATI drivers are causing Windows 8 to crash under certain circumstances when the computer turns off the display or otherwise goes into a lower power mode. I also ran a program called WHOCRASHED that parses the crash logs, and though most of the NT kernel crashes could not be pinpointed to a specific driver, one was attributable to one of the card's drivers.
I set the energy mode to high performance and also turned the clock rate and memory on the cards down about 5%. Everything seems perfectly stable and no more invalid results or computation errors; I'll try to isolate the problem more specifically when I have time.

Fixed.
I turned off the GPU throttling, and set the system never to turn off the display in the energy settings. No crash in 24 hours.
I think I may stay with Windows 7 for my next build.

Great news :) and thanks for sharing the answer to ya problem I will have to re check all my laptop settings and may even go back to windows 7. Also I wanted to say about the temp. post, I didn't mean for it to sound like that was the problem. Some here run around that temp. and even a bit higher. If possible I try to always stay below 60c even if I have to add a house fan "desktop style little fan". This is however my choice. None the less great news on the no crash as of yet and hopefully no more.
