According to this, there are only two choices (page 23 "Host/DRAM
Clock Ratio").

FSB533 probably gives you DDR266 and DDR200 as options.
On FSB400, DDR200 would be the only practical option, as
the even lower setting isn't necessary.

Those ratios are probably coming from the Northbridge memory
controller design. And page 17 here, confirms the two choices.

If you had three double-sided sticks of RAM installed in the
system, I wouldn't wish for an extra high memory clock. It
might not be very stable as a result. If you were running
one stick of RAM, then you could overclock the CPU a bit and see
where it goes.
