That failure might very well be heat-induced. However, know this: I've run my Nvidia GeForce 6800 GT with the core temperature at or near 100 degrees centigrade for extended periods, with no ill effects.


Hmm. Potentially bad news, potentially good news. It only seems to go wrong after playing for a while, so it could be overheating (outside spec), or it could be a batch of VRAM that's oversensitive to the heat (i.e. inside spec).

As a data point, it only goes wrong after the game's been running for 10-15 minutes or so, which (to me) strongly suggests something heat-related.

I'll try that RivaTuner program and see what happens. I'll also try FarCry, and see if the same problem occurs.
