Actualy - for SDRAM this isn't strictly true. Most of the
datasheets show the speed in MHz. Sometimes a 'ns equivalent' value
is shown as well.
The difference between these units is speed (obviously enough), but
to determine this for a random DIMM is hard unless you have a special
test unit. Why don't the markings on the chips suffice?

Harry.
