I have Gigabyte's P55A-UD3R and I don't know much about that voltage stuff (qpi/vtt, etc.). And since I don't want to burn anything I have been thinking about switching all setting that are on "auto" into "normal". But before I do that I want to know what differences these modes have? Also if I'm going to OC my system some more (right now bclk 153, turbo and ht on) when should I start bumping the voltages higher??
