6. If the System Memory value is incorrect, one or more of the DIMMs may not be
installed properly. Repeat steps 1 through 5 again, checking to make sure that the
DIMMs are firmly seated in their sockets.
7. Run the Resource Configuration Utility. Then save the configuration and exit the
utility.
Running the Resource Configuration Utility and saving the configuration is recom-
mended to ensure that the system recognizes the newly installed DIMM(s). See
“Using the Resource Configuration Utility,” in the User's Guide for instructions
on running the utility and saving the configuration.
8. Run the system memory test in the Dell Diagnostics.

2. Align the DIMM's edge connector with the slot in the center of the DIMM
socket, and insert the DIMM in the socket (see Figure 8-5).
The DIMM socket has two alignment keys that allow the DIMM to be installed in
the socket in only one way.
3. Press down on the DIMM with your thumbs while pulling up on the ejectors with
your index fingers to lock the DIMM into the socket (see Figure 8-5).
4. When the DIMM is properly seated in the socket, the ejectors on the DIMM
socket should align with the ejectors on the other sockets with DIMMs installed.
5. Repeat steps 1 through 3 of this procedure to install the remaining DIMMs.
6. Perform steps 4 through 8 of “Performing a Memory Upgrade” found earlier in
this chapter.
