Overview Removing DIMMs
Installing DIMMs
Overview
You can increase system memory up to 768 megabytes (MB) by using synchronous dynamic random-access
memory (SDRAM) dual in-line memory modules (DIMMs).
Figure 3 in "Inside Your Computer" shows the
location of the DIMM sockets on the system board.
When you add system memory, you may install DIMMs in any socket. For optimum operation, Dell
recommends that you install a DIMM in socket A first (closest to the processor) before installing a DIMM in
another socket.
Installing DIMMs
To upgrade memory, perform the following steps.
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals,
disconnect them from electrical outlets, and then wait at least 5 seconds before you remove
the computer cover. Also, before removing the computer cover, see the other precautions in
"
Safety First—For You and Your Computer ."
1. Remove the computer cover .
2. If necessary, remove any DIMMs that occupy sockets in which you plan to install the upgrade DIMMs.
3. Install the upgrade DIMMs.
a. Locate the plastic securing clips at each end of the socket (see Figure 1 ).
b. Press the clips outward until they snap open.
c. Align the two slots on the bottom of the DIMM with the two ridges inside the socket.
NOTE: Make sure to insert the bottom of the DIMM into the socket. The bottom of
the DIMM has two slots.
d. Press the DIMM straight into the slot running down the center of the socket until the
securing clips snap into place around the ends of the DIMM.
