- That's the first I've heard of 1MB*3s. What you're really referring to is
- the fact that they use 1mb*4 bit chips instead of 1mb*1bit chips on the sim.
-
- On an older 1mb * 9 sim, you would have nine discrete 1mb chips.
-
- On a newer 1mb * 9 sim, you would have two 1mb*4 bit chips (= to 1mb * 8)
- + one 1 mb * 1 chip (sometimes they actually use a 1mb * 4 chip here too),
- for a total of three chips.
-
- It should make no difference whatsoever: both types of simms are 1MB * 9 bits,
- just packaged differently. The result should be transparent to the computer.
