Installing Dimms; Removing Dimms - Dell 6100 Supplemental Manual

The system reports that the total memory is 32 MB
less than the actual memory installed. For example,
if your system has 4 GB of memory, the system
reports only 4160512 KB.
Exit and save the system setup information.
NOTE: The value of Extended Memory is given in
kilobytes. To convert kilobytes to megabytes, divide the
kilobyte total by 1024.
If the total is incorrect, one or more of the DIMMs
may not be installed properly. Repeat steps 1 through
10. Make sure that the DIMMs are firmly seated in
their sockets.
11. Enter the system configuration utility. Then save
the system configuration information and exit the
utility.
Running the system configuration utility and saving
the system configuration information are required
for the system to recognize the newly installed
DIMMs. See Chapter 5, "Using the System Configu-
ration Utility," in the User's Guide for instructions on
running the utility and saving the configuration.
12. Run the RAM Test Group in the system
diagnostics.
See Chapter 5, "Running the System Diagnostics,"
in the Installation and Troubleshooting Guide for
information.

Installing DIMMs

The memory module has 32 DIMM sockets arranged in
four banks. Install DIMMs consecutively in groups of
four starting with socket J2.
NOTE: Use only DIMMs approved for use in this system.

To install the DIMMs, use the following procedure.
CAUTION: Handle DIMMs carefully. Hold them
only by their edges. Do not slide them across any
surface. Applying too much pressure on retaining
clips can break the clips or damage the socket.
1. Remove the memory module as described in
steps 1 through 4 of "Performing a Memory
Upgrade" found earlier in this section.
2. Place the memory module flat, with the component-
side up and the memory module oriented with the
edge connectors toward you.
3. Install the DIMM by orienting the pin-1 end of
the DIMM with the pin-1 end of the memory
module socket (see Figure 1).
4. Hold the DIMM at a 90-degree angle to the mem-
ory module and press the DIMM carefully into a
socket until it is held by the retaining clips.
Check for proper installation by ensuring that there
is no gap between the retaining clips and the DIMM.
If the DIMM is not properly installed, remove it
according to the following removal procedure. Then
reinsert the DIMM into the memory module socket.
5. Continue with steps 7 through 12 of "Performing
a Memory Upgrade" found earlier in this section.

Removing DIMMs

To remove the DIMMs, use the following procedure:
1. Remove the DIMMs from the memory module by
starting from the highest-numbered socket.
2. Open the retaining clips just enough to pull the top
edge of the DIMM away from the retaining clips.
3. Pull the DIMM away from the socket, and store it
properly.
