I have a problem with my new gainward gtx 295..every time the gpu reach 75-76° C the system freeze ( no blue screen, no errors, only the system plants..) and the only action to take is to hard-reboot manually ( from case )..
what can be the problem?
Here are some of my pc's specs:
GPU: Gainward GTX295
MOB: Asus P6T
RAM: Corsair Dominator 3GB DDR3 1600
CASE: Antec Nine Hundred Two
CPU: INTEL CORE i7 920 + Noctua NH-U12P SE1366
PSU: ENERMAX REVOLUTION85+ 850W
Last time i have system freeze like that the reason is my oc is not acurate. Just try to run your system without any tweaking or oc, return to the factory default , and do a fresh install of your driver.
If you are a user of windows7 maybe the graphic driver are not good.
The default fan speeds of most graphics cards is less than 60% of the speed they can run at. Using a program such as RivaTuner allows you to manually increase the speed at which the fan turns and therefore improve airflow around the card, lowering temperatures.
What OS? it is abnormal for a vista or windows 7 system to fail like that (if it is due to teh gpu) and not ahve TDR fire at least once. Are there display driver restarts in teh event viewer? Is soemthing else getting hot in tune with the GPU? It stands to reason that if the gPU is under load so is teh rest of the system. Make sure any OC is rock solid, and that the memory/cpu passes memtest as well. Without an error message its hard to say if it is for sure the GPU.
Though I have had hard locsk without BSOD becasue of other components related inone way or another to an OC.
