1-4-2 Installing a Memory
A DDR3 memory module has a notch, so it can only fit in one direction. Follow the steps below to correctly install
your memory modules in the memory sockets.
Step 1:
Note the orientation of the memory module. Spread the retaining clips
at both ends of the memory socket. Place the memory module on the
socket. As indicated in the picture on the left, place your fingers on
the top edge of the memory, push down on the memory and insert it
vertically into the memory socket.
Step 2:
The clips at both ends of the socket will snap into place when the
memory module is securely inserted.

DDR3 DIMM
Before installing a memory module, make sure to turn off the computer and unplug the power
cord from the power outlet to prevent damage to the memory module. DDR3 and DDR2 DIMMs are
not compatible to each other or DDR DIMMs. Be sure to install DDR3 DIMMs on this motherboard.
