NOTE: Ensure the socket ejector latches are fully open, before installing the memory module.
3. Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the
memory module in the socket.
CAUTION: To prevent damage to the memory module or the memory module socket during installation, do
not bend or flex the memory module; insert both ends of the memory module simultaneously.
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in
only one orientation.

memory module evenly.
4. Press the memory module with your thumbs until the ejectors firmly click into place.
When the memory module is properly seated in the socket, the levers on the memory module socket align with the levers on
the other sockets that have memory modules installed.
