edge of the DIMM. Be sure to press straight into
the connector. Be sure that the retaining clips

are in the
closed position. If a gap exists between the
DIMM and the retaining clips, the DIMM has not
been properly installed. In this case, open the
retaining clips and remove the DIMM; then,
reinsert the DIMM.
d. Repeat these steps for each memory module
that you install.
