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. The module should pop up slightly 
(see Figure 8).
4. Lift the memory module out of its socket.
	
##
1. If you only have one memory module, install it in the DIMM A socket.
NOTES: 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.
Memory modules are keyed, or designed to fit into their sockets, in only 
one direction. The slots on the system board are notched so that the mem-
ory module can be firmly seated only one way.

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. 
3. 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.
