The ECS K7S5A PRO does not have any adjustments for Multipliers on jumpers or in bios. With SpeedFan and CPUFSB you will be able to change the FSB but not the multiplier. A couple of days ago there was a page floating around here that showed how to wire mod the socket for different multipliers. No welding, just placing stands of thin wire from one hole in the socket to another in a particular order for each multiplier. This will work with CPU's that are not Locked. I have read in other forums where some people have welded, and modded there boards to adjust multipliers, but that is way to involved, and probably more expensive than a new board with adjustments.
