Banks A, B, and C can be Þlled in any order as long as both slots in the bank are Þlled. It is
easiest to start with the last clip in Bank C. Insert the rightmost SIMM of a pair Þrst.
If you are installing SIMMs in bank A, loosen the rightmost SIMM in the motherboard bank
to get the leftmost bank A SIMM in.
All SIMMs must be 72-pin, fast-paged mode, 80-nanosecond RAM access time or faster.
Slower SIMMs will not work reliably. 30-pin SIMMs from older Macintosh computers and
DIMMs (Dual In-line Memory Modules) from PCI Macintosh computers are not
compatible. Make sure that the memory modules you purchase are the right ones for your
computer.
To increase your systemÕs RAM. install additional SIMM modules in vacant DRAM banks;
if there are no vacant banks, replace installed SIMM modules with modules of higher
capacity.
