memory question (pc100 - pc133)

How can you tell pc100 from pc133 modules?

I mean, from looking at them.

Thanks,

Mike

Look at the part number on the chips. There is a "-" and
then a number, and that number is the clock time in
nanoseconds. The inverse of that time gives the clock rate.

You can see some examples here. Notice how the -75 or 7.5ns
is 133MHz or PC133. I cannot find any examples of datasheets
for PC100, but would assume there would be a similar
relationship between the "dash-number" and the speed.
