GTX 460 (GV-N460OC-1GI)

Hi!

I currently own a GTX 460 1GB (GV-N460OC-1GI). I have overclocked the card to 875Mhz on the core and 2000Mhz on the memory.
For this to work I needed to up the voltage to 1.062V. After running OCCT for 10 minutes, the screen go blank (e.g black as in no signal) and I have to reboot. No errors was detected during this time and the core temp reached 81 degress Celsius. This ofcuz only occurs when I run OCCT and I am fully aware that this software has any GPU on it's knee's. If I back a little on the memside and lower it to 1800Mhz, I can run the same program (OCCT) for 1h or more without errors. With 850 on the core and 2000 on the mem, I can do the same.
What I really would like to know is what happens after 10 min at that temperature, cuz I know the GPU can handle that temperature quite easily.
It's specified for the same temperatures as the GTX480, which has a maxtemp of 105 degress Celsius.

The blank screen is not a normal crash cuz usually if I go to high the driver stops working and the app running crashes.

Hi
Only guessing but from what you have said I would expect that it isn't the GPU that is overheatiing at all but the power chips/VRMs and that they are the ones that can't handle the heat.

Thank you for the quick answer. *takes a bow*

It could also be a million other things... you should consider giving us your system's specs when posting an overclock. Anw if I were you I would try the overclock with my case open and or a fan pointed straight at the card to see if something else is overheating... Also try running loops of 3D mark to see if you got any artfacts to make sure the voltage your giving it is enough. I graphics cards since my GT 7800 and quite honestly apart from bragging rights I dont think its worth the performance cause the heat those things put in your case is just immense.
