i had the same asus board, and the reason its showing the 6x multiplier is the power saving functions of the processor. When you start using it again, it will raise the multiplier back up to what it needs to be at. On my Q6600, i can get away with 1.35v and get 3.4Ghz and be 100% stable, but i have a G0 stepping, so i have a little more overclock headroom than you probably do. I have mine set at 425x8 and 1.35 volts to get 3.4 with higher FSB.
