1.7.3 Installing a DIMM
Make sure to unplug the power supply before adding or removing DIMMs or
other system components. Failure to do so may cause severe damage to both
the motherboard and the components.
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.
1.7.4 Removing a DIMM
To remove a DIMM:
1. Simultaneously press the retaining
clips outward to unlock the DIMM.
2. Remove the DIMM from the socket.
Support the DIMM lightly with your fingers when pressing the retaining clips.
The DIMM might get damaged when it flips out with extra force.
• 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.
• The DDR2 DIMM sockets do not support DDR DIMMs. Do not install DDR
DIMMs to the DDR2 DIMM sockets.
