I've got the same system, from what I've gathered, we got the throwbacks of the KX133 chipset, you can probably only run 100mhz (200ddr)fsb processors on it.
the only option for overclocking the processor, as the uninformed have told you to do, is to modify the bridges on the processor itself. there are no bus speed nor multiplier options on this board.
go with a 1.3, 200mhz if you want, but be prepared for troubles, I don't think the board was designed with that kind of power drain in mind.
btw: I have a 1Ghz in mine now, doesn't run too well with the Geforce 2 MX either... one or the other has to go to run wide open.
why, oh WHY, is the world run by morons?
