16-MB single-density as well as 8-MB, and 32-MB double-density

also support 64-MB SIMMs, when available, to achieve 384-MB
system memory.

Rules for Adding Memory

•
Use only the same type of SIMM in a given bank
•
You may combine different types of SIMMs for a particular
memory configuration as long as the SIMMs in each bank are of
the same type.
•
Always install SIMMs in pairs. For example, for a total memory
of 16 MB, install two 8-MB SIMMs into the sockets marked S6
and S5 (bank 1) or S2 and S1 (bank 3). You can not use a
16-MB SIMM alone for a 16-MB memory.
•
Always install SIMMs starting from an inner socket.
example, install SIMMs in socket S6 before in socket S5, or in
socket S2 before socket S1.
•
Always remove SIMMs starting from an outer socket.
example, remove SIMMs in socket S5 before in socket S6, or in
socket S1 before socket S2.
