Question about putting ACC -2% to all four cores. What exactly does it do? I have a X2 unlocked to X4 overclocked to 3.8ghz (19multix200) at 1.456v. Settings are hyper,ACC all cores -2%. I am trying to get it to 3.9 or 4.0ghz. Does the settings i modify in the ACC affects my clocks? I might be limit out.. but I have a feeling that i can squeeze out another 100 or 200mhz. Please help me out here. Temps are fine, idles at 38c full load while running prime is around 55-58c on Zalman9900 air cooler. PSU is good, putting out enough power. Should i try to raise the north bridge voltage a bit? because is on stock voltage now. Voltages are all stock except Core and Vdim. Any suggestions would be appropriated.
