This section includes instructions for removing and installing DIMMs on
the memory board.

DIMM sequence

Load the DIMMs in the following order:
• Bank 1: DIMMs #1, 2, 3, and 4
• Bank 2: DIMMs #5, 6, 7, and 8
• Bank 3: DIMMs #9, 10, 11, and 12
Always fill banks completely. Partially filled banks are ignored by the
system.

To install DIMMs

Caution! Use extreme care when installing a DIMM. Applying
too much pressure can damage the socket. Keyed DIMMs insert
only one way.
1 Remove the memory board (refer to page 52), and place the board
component-side up on a nonconductive, static-free surface.
2 Holding the DIMM only by its edges, remove it from its antistatic
package.
3 Open the plastic ejector levers (Figure 25, A) at each end of the
DIMM socket on the memory board .
