I have overclocked my G3258 to 3.8 GHz without changing any voltage (not much, I know, but it isn't stable at 4.0). Problem is, there are 3 types of voltages I can change. I am running an MSI mATX "military class" motherboard and the voltages are: VCCIN, CPU core voltage, and CPU ring voltage. Which do I increase? They are on auto and when I press +, the VCCIN is at 1.2, and the other two are at 0.8, even though when running benchmarks the CPU voltage is higher than that. Should I change voltage and leave on auto or go to override mode? Thanks.
