6800GT Crashes and hard reboots - FIXED

[bluegnu]

This may help some people, which is why I'm posting.

I was experiencing game freezes (checkerboard graphical glitches) which were requiring a hard reboot to fix. Tried the patch...no fix. Tried rolling back to older Nvidia drivers...no difference.

Stupidly I assumed the fault was with the game, driven largely by the huge amount of problems people were/are having with it. However, I did decide to check and see whether it might be hardware related, and low and behold! the core temp of my 6800 was running 115 degrees. A quick repositioning of my PCI card setup to allow more airflow and guess what? Not one crash since.

So...if you are experiencing similar problems it might well be worth you checking how hot your card is running. You never know.

How odd.

The default Core Slowdown Threshold is 145 degrees celcius (I have a 6600GT and 81.95 drivers). You should be fine up to the temperatures you're reaching.

I wonder what's going on?

How do you find out how hot your system is running?

Good point. Hadn't really thought about it, but my cards default
Core Slowdown is set at 120 degrees. So...maybe it's not a factor of the core temp getting too high, yet increasing ventilation has cured the fault.

In answer to the other question: You can see what temp the card is running at by checking in the Nvidia Properties > from the desktop.
