so about my board not working very well with OC what is the safest OC i can get away with? I’d like to hit 4 Ghz if possible
A better board, cheaper too, would be the Asrock z77 Extreme4. 4.0 is easy to hit, if your serious about overclocking you should set a goal of 4.4-4.5 and shoot for that. 4.0 is really only .3ghz faster than stock, and you would not notice any difference whatsoever.
Think of it this way:
Power phases are like highway lanes, the less you have, the more chance cars can get jammed in them. The cars can get jammed like traffic, because there aren't enough lanes for those cars to get to. In this case, car=clean power to the CPU, the more lanes you have the more cars you can carry, resulting in more clean power to the CPU!
Thanks. I think I may do a bit more reading on this because now I am curious as to what power phase I have.
