Hold the memory module by its edges. Don't touch the gold contacts with your fingers. If you do, wipe the contacts with a clean, lint-free cloth to remove any finger oils.

Orient the module with the label facing down and align the gold contacts with the socket.

Insert the contact edge into the socket at a shallow angle. The gold contacts should mostly be covered by the socket.

Press the edges of the memory module down until the side clips lock it in place.
