DIMMs
The processor/memory board contains eight DIMM
sockets labeled M1 through M8 (Figure 5-5). Each
socket can hold a single 72-bit DIMM module with
32MB, 64MB, or 128MB of memory. When all eight
sockets are populated, the processor/memory board
supports a maximum of 1GB of memory with 128MB
DIMMs. The first DIMM should be installed in the first
(M1) socket and subsequent DIMMs installed in
sequence (M2 - M8).
Installing DIMMs
When properly installed, the DIMM module is oriented
at an angle of 90 degrees relative to the
processor/memory board.
1. Remove the processor/memory board as described
earlier in this section.
Notice: Observe static precautions. Use an antistatic
wrist strap. Hold DIMMs only by their edges.
2. Holding the DIMM module only by the edges, remove
it from its antistatic package.
3. DIMMs are keyed so they can only be inserted one
way. Position the DIMM over the socket on the
board (Figure 5-5, A and B). The notches in the
bottom edge of the DIMM mates with the raised
bumps in the DIMM socket.
