My over clock incressed!? Are you talking the differnce in the Max Bios and the Rampage Bios!? If that is the Question, then the answer is yes. I was able to go 3.1 stable in prime with stock volts. Then at 3.3 I had to jump up the NB once to get it Prime stable... Now, I'm just going to see If I can get a setting to go and try 4ghz... I'll type out the settings I was trying at when I was getting the IRQ error... Then Tonight I'll be trying my Striker II board again.. I have a feeling that board wasn't dead... Now that I know The Asus Bios..
