Hello and from me After I flashed my bios and unlocked overclock settings in invidia inspector for my video cards (650m sli) I cant get any stable overclock. I play 10-15 min (for example CS:GO) then screen go black for 10 seconds and my clock are stock again... I lower the overclock but same thing... even +50 MHz (mem and base) I tried with different voltages too... no changes. When they went back to normal after the black screen everything run normal no problems. I use latest Nvidia drivers, may be they are the reason I dont know. My os is Windows8.1 If someone has some kind of solution or something please share buy for now
