System Memory: Dell™ OptiPlex™ GC System User's Guide
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 3 in "Inside Your Computer" shows the location of
the DIMM sockets on the system board (DIMMs must be non-error checking and correction
[non-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.
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 their electrical
outlets, and then wait at least 5 seconds before you remove the computer cover. Also,
before you upgrade memory, see the other precautions in "Safety First—For You and Your Computer. " |
- Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."
- If necessary, remove any DIMMs that occupy sockets in which you plan
to install the upgrade DIMMs.
- Install the upgrade DIMMs.
- Locate the plastic securing clips at each end of the socket (see Figure 1).
- Press the clips outward until they snap open.
- 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.

- Replace the computer cover, and reconnect your computer and
peripherals to their electrical outlets and turn them on.
- Enter System Setup and verify that the memory total shown on the System Information screen matches the amount now installed in the computer.
- If the memory total is incorrect, turn off and disconnect your computer and peripherals
from their electrical outlets. Remove the computer cover, rotate the power supply, and
check the installed DIMMs to make sure that they are seated properly in their sockets.
Then repeat steps 3 and 4.
- Run the Dell Diagnostics to verify that the DIMMs are operating
properly.
To remove a DIMM, press the securing clips outward simultaneously
until the DIMM disengages and pops out slightly from the socket (see Figure 2).
