How many of you with BE processors just crank the multiplier up? I am find myself curious as to why most reviewers simply crank up the multiplier instead of doing it like everyone else and messing with the reference clock to get faster speeds. Do you get the same performance increase by a higher multiplier that you get when you tune everything to the reference clock (such as memory, HT Link, North Bridge). I can get my Athlon II X4 620 stable at 3510 mhz and playing with all the ratios, but as a max out this processor I am considering a Phenom II. From what I read I've gotten about as much over clock out of my Athlon II as I'm going to get.
