Just built an athlon 64 3500 system, 2 gigs ram, 6800 gt 2 x 200gb hdd's in raid 0, msi neo2 platinum mb, problem is I am not getting how to overclock it in the bios. I try adjusting the fsb up but its not doing anything, there is a multiplier.. only options are 4x to 11x although the manual shows its suppose to go up to 20x. what am I missing? anyone here have experience with overclocking a64's with this mainboard? this is my first athlon 64 system, and first non gigabyte/asus board as well.
