Memory Module Installation
Figure 10 below displays the notch marks as they should look on your DIMM
memory modules.
DDR DIMMs have 184-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 (Figure 3-1) until it fits tightly into the
DIMM socket.

Installing a DIMM
Carefully follow the steps below in order to install the DIMMs:
1. 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.
2. Do not touch the connectors of the DIMM. Dirt or other residue may cause a
malfunction.
3. Hold the DIMM with its notch aligned with the memory socket of the
KEMX-4040 and insert it completely into the socket. Lift the locking tabs at each
end of the DIMM socket to lock it in position.

4. If you install two DIMMs, install the second DIMM using the same procedure as
above.
5. If the DIMM does not go in smoothly, do not force it. Pull it all the way out and
try again.
6. Make sure the DIMM is properly installed and locked by the tabs on both sides
of the socket.
Removing a DIMM:
To remove the DIMM, use your fingers or a small screwdriver to carefully push away
