The issues on backwards compatibility of PC133 and PC100 with PC66 is as old
as the hills.  PC-66 came in two distinct varieties:  2 clock and 4 clock,
whilst PC100/PC133 is 99.99% 4 clock.  If the machine requires 2clock PC66
then 4 clock PC100 and PC133 will not work.  This was an accute problem with
the TX chipset.

PC66 is in usually far more expensive than PC100/PC133 as the modules/chips
have not been manufactured for over 4 years.
