"The DFI AK74 offers FSB increments of 1MHz from 100-133. Now on a VIA Apollo Pro A motherboard, 1MHz FSB increments, would be great for oveclocking that Pentium 3 600e. But unfortunately the Duron/Athlon Bus system, is not a great overclocker. The DFI AK74 does not offer any voltage increases and I was only able to push a Duron 700 to 105MHz Front Side Bus. Not much of an overclock."
