as far as i know, i cannot raise my agp voltage on my graphic card and not going to inted to since it's very hot itself on stock speed already. i could only manage a 10mhz overlocking on both gpu and memory. SUCKS
about the setting to 2x, wouldnt it mean then it will only run at 156mhz? that's not even with the usual 4x which supposed to be 266Mhz
sure, i'll run 2x for a while and let's see how it is... but now i think it's my monitor that has some problems, because when i run at 75khz it still flickers, and when i run it at 85khz it it refreshes from time to time..
