I'v been having trouble with my XT, basicly it randomly crashs, forcing me to reboot. One time the GPU recovery worked most time it doesn't. I beilve it's from overheating, so i'v been using ATI tool to log my temps, and to keep my card unclocked. i'v been running at 231/272 to keep my system stable. Which still leaves me in the 79-90C's. I am just wondering if anyone knows how hot the card can safely run before it should start causing problems.
