1. Remove the memory module cover.
2. To avoid possible damage to the memory module from electrostatic
discharge (ESD), ground yourself by touching the unpainted metal surface
of an I/O connector on the computer’s back panel.
3. To release a memory module from its socket, carefully spread apart
the inner tabs of the memory module socket just far enough for the
memory module to disengage from the socket (it should pop up slightly)
(see Figure 7).
4. Lift the memory module out of its socket.
If you only have one memory module, install it in the DIMM A socket. Memory
modules arekeyed, or designed to fit into their sockets in only one direction.
The slots on the system board are notched so that the memory module can be
firmly seated only one way.
Align the memory module’s edge connector with the slot in the center of the
memory module socket. With the module at a 45-degree angle, press the
memory module’s edge connector firmly into the memory module socket.
Pivot the memory module down until it clicks into place. If you do not hear a
click as each end of the memory module snaps into the tabs, remove the
memory module and reinstall it.
NOTE: 192-MB memory modules are designed for either the socket labeled
DIMM A or the socket labeled DIMM B; they are not interchangeable. Be sure
that the memory module is inserted with the double-stacked memory chips
facing you. A 192-MB memory module inserted with the double-stacked
memory chips facing down does not fit properly in the socket.
