Ok so i used ntune or nvidia control panel to overclock the memory bus and core bus. this worked fine and i did it in increments playing crysis in between till i got to the point where there were artifacts then i backed it down a notch. so i see improvemnet but the settings dont stay. from reading around i guess i have to do a bios flash is this correct? would the one sticky on flashing the bios be what i have to do?
