To replace a DIMM, orient the DIMM so that the cutouts on its edge connector
align with the crossbars in the central groove of the socket, as shown in
Figure 4-20. Insert the DIMM straight down into the socket, making sure that it
fits into the vertical guides at each end of the socket. Press firmly until the
DIMM snaps into place.
