Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and peripherals.
Open the system.
Remove the cooling shroud.
Removing the memory Modules:
Locate the appropriate memory-module socket(s).
To release the memory-module blank from the socket, simultaneously press the ejectors on both ends of the memory module socket.
If a memory module or a memory-module blank is installed in the socket, remove it.
Installing the Memory Modules:
Align the memory-module's edge connector with the alignment key of the memory-module socket, and insert the memory module in the socket.
Press down on the memory module with your thumbs until the memory module snaps into place.
Repeat above procedure to install the remaining memory modules.
Replace the cooling shroud.
Close the system.
Reconnect the system to its electrical outlet and turn on the system, including any attached peripherals.
Press <F2> to enter the System Setup, and check the memory settings. The system should have already changed the value to reflect the newly installed memory.
If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat the steps, checking to ensure that the memory modules are firmly seated in their sockets.
Run the appropriate diagnostic test. For more information, see Using System Diagnostics.
