When computer manufacturers specify a SIMM speed, they're telling
you the slowest speed that will work.  Anything faster than that
will work just as well.  Faster SIMMs probably won't result in a
faster computer, however, since the motherboard probably won't be
ready to received the data much faster than a SIMM of the specified
speed would supply it.

Not necessary -- the SIMM itself tells the motherboard when the
data it asked for is ready for collection.
