thank you for taking the time to field my question. i just took delivery of my shiny new asus p8p67 pro motherboard. in the manual there is a section regarding overclocking etc and the acronym "d i g i" and "vrm" are used . i can't find what these letters mean in the asus website, google or bing. i would be very grateful if you could clear this up for me. thanking you in advance, allen dyer vancouver island bc.
