Below 200, in the 190's, they are in 1 Mhz steps. But just above 200, they are not. What I remember from looking at it during the last boot was: 200, 203, 204, 206, 207 (I think), 208. So that could be a bummer if you are trying to squeak every last bit of juice out of 400 Mhz DDR.
But I'm happy with it. I'm at 11x193 FSB (2123) with my 2100+. (I'm picky about stability, and anything much over this will generate prime95 errors, though sometimes not for hours.) Getting 16500+ 3d marks.
