Memory Module Installation
Figure below displays the notch marks as they should look on your DIMM memory
modules. DDR2 DIMMs have 240-pins and one notch that will match with the onboard
DIMM sockets. DIMM modules are installed by placing the chip firmly into the socket
at a 90-degree angle and pressing straight down until it fits tightly into the DIMM
socket.

Installing a DIMM
Carefully follow the steps below in order to install the DIMMs:
To avoid generating static electricity and damaging the DIMM, ground yourself by
touching a grounded metal surface or using a ground strap before you touch the
DIMM.
1. Do not touch the connectors of the DIMM. Dirt or other residue may cause a
malfunction.
2. Hold the DIMM with its notch aligned with the memory socket of the
motherboard and insert it completely into the socket. Lift the locking tabs at
each end of the DIMM socket to lock it in position.
3. If you install two DIMMs, install the second DIMM using the same procedure as
above.
4. If the DIMM does not go in smoothly, do not force it. Pull it all the way out and try
again.
5. Make sure the DIMM is properly installed and locked by the tabs on both sides
of the socket.
