Glad someone is having the same questions I'm having. I have the same setup, i5 3570k on Asus p8z77-v pro with cooler master 212 evo cooler. Auto overclocked and got pretty much the same results, 4.5 ghz. However i dont understand all the settings and after reading the board, decided to just go back to default and try to figure out how to manually do it. Still tryin to figure it all out, but it did seem to run fine with the auto oc.
