System Memory: Dell OptiPlex GX200 System User's Guide
You can increase system memory up to 1 gigabyte (GB) by using Rambus
in-line memory modules (RIMMs). Figure
9 in "Inside Your Computer" shows the location of the RIMM sockets on the
system board.
 |
NOTES: To reach the maximum 1-GB memory total, you
must install two 512-megabyte (MB) RIMMs (when available) that each have a maximum of 16
memory devices. The system supports no more than a total of 32 memory devices on all
installed RIMMs. See Figure 1 for the location of a
label on the RIMM that identifies the number of memory devices it contains. You can also
determine the number of memory devices installed through the System Memory option in System
Setup. All RIMM sockets must be occupied either by a
RIMM or a continuity card. |

For optimum performance, Dell recommends that you install a RIMM in
socket A first (closest to the processor) before installing a RIMM in socket B.
 |
NOTE: Before disconnecting a peripheral from the
system or removing a component from the system board, verify that the standby power
light-emitting diode (LED) on the system board has turned off. For the location of this
LED, see Figure 9 in
"Inside Your Computer." |
 |
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer from the Dell Support website at support.dell.com. |
To upgrade the system memory, perform the following steps.
- Remove the computer cover.
- To access the RIMM sockets on the system board, rotate the power
supply.
- If necessary, remove any RIMMs or continuity modules (C-RIMMs) that occupy sockets in
which you plan to install the upgrade RIMMs.
 |
NOTE: Retain any C-RIMMs to enable future upgrades.
|
- Install the upgrade RIMMs (see Figure 1).
Locate the plastic securing clips at each end of the socket. Press the clips outward
until they snap open. Press the RIMM straight into the slot running down the center of the
socket until the securing tabs snap into place around the ends of the RIMM.
 |
NOTE: All RIMM sockets must be occupied by either a
RIMM or C-RIMM. |

- Rotate the power supply back into position, making sure the securing
tab snaps into place.
- Replace the computer cover, and reconnect your computer and
peripherals to their power sources and turn them on.
After you remove and replace the cover, the chassis intrusion
detector causes 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 System Setup, and
check the value for System Memory.
The system should have already changed the value of System
Memory to reflect the newly installed memory. Verify the new total.
 |
NOTE: If the memory total is incorrect,
turn off and disconnect your computer and peripherals from their power sources. Remove the
computer cover, rotate the power supply, and check the installed RIMMs to make sure that
they are seated properly in their sockets. Then repeat steps 5, 6, and 7. |
- While in System Setup, reset the chassis intrusion detector by
changing Chassis Intrusion
to Enabled or Enabled Silent.
 |
NOTE: If a setup password has been
assigned by someone else, contact your network administrator for information on resetting
the chassis intrusion detector.
|
- When the System Memory total is correct, press the
<Esc> key to exit the System Setup program.
- Run the Dell Diagnostics to verify that the
RIMMs are operating properly.
To remove a RIMM, press the securing clips outward simultaneously
until the RIMM disengages from the socket (see Figure
2). It should pop out slightly.
