The memory board contains sixteen DIMM sockets
(Figure 5-5) arranged in four banks. Each 168-pin
socket can hold a single 72-bit DIMM module with
32MB, 64MB, 128MB, or 256MB of memory. When all
sixteen sockets are populated, the memory board
supports a maximum of 4GB of memory with 256MB
DIMMs. DIMMs must be identical within a bank.
When properly installed, the DIMM module is oriented
at an angle of 90 degrees relative to the memory board.
1. Remove the 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.
