8. Insert the DIMM into the connector by aligning the edges of the DIMM with the slots at the ends of the
DIMM connector (see “System-board optional-device connectors” on page 32 for the locations of
the DIMM connectors).
9. Firmly press the DIMM straight down into the connector by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the DIMM is firmly seated
in the connector.
Note: If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly
inserted; open the retaining clips, remove the DIMM, and then reinsert it.
