1.7.3 Installing a DIMM

Follow these steps to install a DIMM.
1. Unlock a DIMM socket by pressing the
retaining clips outward.
2. Align a DIMM on the socket such that the
notch on the DIMM matches the break on
the socket.
3. Firmly insert the DIMM into the socket
until the retaining clips snap back in place
and the DIMM is properly seated.
A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT
force a DIMM into a socket to avoid damaging the DIMM.
