2.6.2 DIMM installation
To install a DDR2 DIMM:
1. Locate the Four DIMM sockets on the
motherboard.
2. Unlock a socket by pressing the retaining clips
outward.
3. Align a DIMM on the socket such that the notch on
the DIMM matches the break on the socket.
4. Firmly insert the DIMM into the socket until the
retaining clips snap back in place and the DIMM is
properly seated.
A DDR2 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!
