I pulled this from the old sun hardware FAQ.  Hope it helps.

MEM LAYOUT: Memory consists of up to sixteen 1M (501-1408) or 4M
                (501-1625 or 501-1739) x 9 30-pin 80 or 100ns SIMMs, in
                four banks. The SIMM slots span the middle of the board,
                in two columns.

                Banks must be filled in the order 0, 2, 1, 3, and SIMM
                types may not be mixed within banks.
