Installing Memory Modules
1. Open the system. See " Opening the System " in Troubleshooting Your System."
2. Locate the memory module sockets. See Figure 6 -1 .
3. Press the ejectors on the memory module socket down and out, as shown in Figure 6 -6 , to allow the memory module to be inserted into the socket.
4. Align the memory module's edge connector with the alignment keys of the memory module socket, and insert the memory module in the socket.
5. Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the memory module into the
socket.
When the memory module is properly seated in the socket, the ejectors on the memory module socket align with the ejectors on the other sockets that
have memory modules installed.
6. Repeat step 2 through step 5 of this procedure to install the remaining memory modules.
7. Close the system. See " Closing the System " in "Troubleshooting Your System."
8. (Optional) Press <F2> to enter the System Setup program, and check the System Memory setting on the main Setup screen.
The system should have already changed the value to reflect the newly installed memory.
9. If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 1 through step 8 of this procedure, checking to
ensure that the memory modules are firmly seated in their sockets.
10. Run the system memory test in the system diagnostics. See " Running the System Diagnostics ."
