Since the ICs for the reduction circuit are getting harder and harder to find, I was thinking that any build I do will involve dual bios options for 1.4GHZ and 733MHZ. That would require that the underclocked bios be set to 66/67MHZ FSB. My question is, would slowing things down that much affect things like memory speeds or anything else affected by it to a degree that would be noticeable? Will I create a bottleneck anywhere else in the system by clocking the FSB that insanely low?
