[ReTiCuLeX]

Well so far my systems runing stable I think im gona go ahead and overclock with my watercool kit instead of my hsf but first I need to find out is there a bios to change the multiplier on the board without modifying it ? If not does any one know how to modify the a7m266 easier then what the current sites say ? My asus board has 4.7ohm resisters alrdy on it so do I still gota modify it with differen't resisters ?
