System Memory: Dell™ OptiPlex™ GX1 Small-Form-Factor
System User's Guide
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.
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." |
- Remove 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.
- 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. |
- 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.
|
NOTE: Press the top center of the DIMM,
and then press the top corners of the DIMM. This action firmly seats the DIMM in the
socket, which allows the securing clips to snap into place around the end of the DIMM. |

- Replace the computer cover,
and reconnect your computer and peripherals to their electrical outlets and turn them on.
|
NOTE: If Enabled, the Chassis Intrusion option will cause the
following message to be displayed at the next system start-up:
ALERT! Cover was previously removed. |
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
- Press <F2> to enter the System Setup program, and check
the value for System Memory.
The system should have already changed the value of System Memory
to reflect the newly installed memory modules. Verify the new total. If it is correct,
skip to step 7.
- If the memory total is incorrect, turn off and disconnect your
computer and peripherals from their electrical outlets. Remove the computer cover, and
check the installed DIMMs to make sure that they are seated properly in their sockets.
Then repeat steps 4 and 5.
- When the System Memory total is correct, press
<Esc> to exit the System Setup program.
- 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 from the socket (see Figure 2). It should pop out slightly.
