Figure 2-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket.
A DIMM must occupy the black XMM1 socket.
For maximum performance, populate the sockets so that the memory capacity is spread as equally
as possible between Channel A and Channel B. Refer to
Populating DIMM Sockets on page 15
for more information.
8. Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted and
properly seated. The DIMM must be pushed all the way down into the socket and sit evenly in the
socket to avoid memory corruption. Make sure the latches are in the closed position (3).
9. Repeat steps 7 and 8 to install any additional modules.
10. Replace the computer access panel.
11. Reconnect the power cord and any external devices, then turn on the computer. The computer
