The IIsi has 1 Mb on board plus 4 SIMM slots that take 256K, 512K, 1meg, 2meg
and 4meg SIMMs in sets of four. Thus the possibilities are 1, 2, 3, 5, 9 & 17
megs. (1meg + (4 x SIMM size))

Realistically, the best value would be 1meg SIMMs which brings you up to 5Mb.
For the price Apple charges for other SIMMs, it's probably not worth going
to 3Mb.
