System Memory: Dell™ OptiPlex™ GX100 System User's Guide
Overview
You can increase system memory up to 512 megabytes (MB) by using synchronous dynamic random-access memory (SDRAM) dual in-line
memory modules (DIMMs).
Figure 7
in "Inside Your Computer" shows the location of the DIMM sockets on the system board (DIMMs must be non-
error checking and correction [ECC]).
When you add system memory, you may install DIMMs in either socket. For optimum operation, Dell recommends that you install a DIMM in socket
A first (closest to the processor) before installing a DIMM in socket B.
Installing DIMMs
To upgrade memory, perform the following steps.
1. Remove the computer cover according to the instructions in "
Removing and Replacing 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. Press the DIMM straight into the slot running down the center of the socket until the securing tabs snap into place around the ends
of the DIMM.

4. Replace the computer cover, and reconnect your computer and peripherals to their electrical outlets and turn them on.
The system detects that the new memory does not match the existing system configuration information and generates the following
message:
The amount of system memory has changed.
Strike the F1 key to continue, F2 to run the setup utility
