3. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 8-6 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 XMM4 socket. Always populate XMM4 before XMM2, and XMM3 before
XMM1 (populate the black sockets before white sockets in each channel).
A DIMM must occupy the black DIMM1 socket.
Populate the DIMM sockets in the following order: DIMM1, DIMM3, DIMM2, then DIMM4.
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
for more information.
4. Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).
5. Repeat steps 3 and 4 for any additional modules that you want to install.
NOTE: The computer automatically recognizes the additional memory when turned on.
