Steps
1 To open the memory riser, open the flip out brackets on the memory riser.
2 Locate the appropriate memory module socket.
CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or
metallic contacts.
3 Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket.
4 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: Do not apply pressure at the center of the memory module; apply pressure at both ends of the memory module
evenly.
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in only
one orientation.
5 Press the memory module with your thumbs until the socket levers 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.
