8. To install the DIMMs, repeat the following steps for each DIMM that you install:
a. Turn the DIMM so that the DIMM keys align correctly with the connector on
the system board.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, handle the clips gently.
b. Insert the DIMM by pressing the DIMM along the guides into the connector.
Make sure that the retaining clips snap into the closed positions.
Important: If there is a gap between the DIMM and the retaining clips, the
DIMM has not been correctly installed. In this case, open the retaining clips
and remove the DIMM; then, reinsert the DIMM.
