my 955 c2 didnt like high volts at all.... my 940 took the volts way better than 955 and actually had a higher validation, but the 955 need less volts to get higher stable clocks (around 1.5v for 3.75ghz on 940 prime stable, 1.48v for 3.85ghz prime stable on 955..) i could barely even bench my 955 over 1.5v let alone try to prime on it
