Installing a DIMM
To install a DIMM, align it with the socket and press it down until the
holding clips secure the DIMM in place.
The DIMM socket is slotted to ensure proper
installation. If you slip in a DIMM but it does
not completely fit, you may have inserted it
the wrong way. Reverse the orientation of
the DIMM.
