That may be a problem then. If it's PC66, then PC100 or PC133 may not
work. I have an Intel motherboard that uses PC66 RAM and it refuses
to work with PC100 or PC133. I actually get a message on the screen
that the RAM is the wrong speed.
Some PC100 RAM will work at the slower speed, some won't. I've never
tried PC133, but the refresh may be too slow and data will fall off......
Come to think of it, I have some Wallstreet laptops that take PC66 RAM
(and some that take PC100 RAM ). The 100s will work with PC100 and PC133,
but the 66's require 66 or 100.
