At what temp does a 1900+ XP fry at. I just ordered one for my KT400 Dragon Ultra. For those that don't know it will shut down if the chip hits 85C. Unless you change it from default, which as soon as I can I will lower it to bout 50C.
According to AMD's specs the chips can handle temps of 90-95c but I wouldn't test that out. Theoretically shutting down at 85c should save your chip but I have mine set to shut down at like 55c b/c you never know how long it will take your board to shut it down once it hits the high temp (meaning if your heatsink falls off it will take a fraction of a second for your chip to overheat and I dont know if the board can shut the chip down that fast, so the lower the shutdown temp the more time you have to to get the system off before it cooks).
