Basically, when I increase the core clocks along with shader clocks (or just core clocks), and then I open a game or something, the driver crashes, and the card underclocks itself (to 405 mhz core clocks etc). I then have to reboot for it to restore the original clocks (550, etc). I am not significantly increasing the clocks either, just a little bit (20hz or so, just to see what is stable and what is not).

I read somewhere that it might have to do with voltage, or the GPU BIOS as stated above? Maybe it is just EVGA Precision... I will try other software to see if I have any luck.

Bump

I tried using MSI Afterburner but still had no success. I saw that I couldn't change the core voltage either. Also, it comes up with an error when I close it or apply something.
