Ive been trying to hit at least 4.5 ghz but i seem to be stuck at 4.4 at 1.18v with LLC at extreme. i cant seem to get any higher. I know that my voltage is in good range for now. What am i doing wrong? I havent really played around with other voltages much at 4.5ghz(only 1.2, 1.21, 1.25 and 1.3) could my processor be at its limit already with such a voltage of only 1.18? please help!
