Whenever you install more than one SIMM, they should be matched. Usually you
can get away with different speed just by setting the computer to access at
the slowest SIMMs speed.

Yes, but that was with 16bit modules. If you put 32bit modules into a 32bit
machine, they don't have to be doubled up. Same with 64bit DIMMs, in a 64bit
machine only one is needed to work.
