The system reports that the total memory is 32 MBless than the actual memory installed. For example,if your system has 4 GB of memory, the systemreports only 4160512 KB.Exit and save the system setup information.NOTE: The value of Extended Memory is given inkilobytes. To convert kilobytes to megabytes, divide thekilobyte total by 1024.If the total is incorrect, one or more of the DIMMsmay not be installed properly. Repeat steps 1 through10. Make sure that the DIMMs are firmly seated intheir sockets.11. Enter the system configuration utility. Then savethe system configuration information and exit theutility.Running the system configuration utility and savingthe system configuration information are requiredfor the system to recognize the newly installedDIMMs. See Chapter 5, “Using the System Configu-ration Utility,” in the User’s Guide for instructions onrunning the utility and saving the configuration.12. Run the RAM Test Group in the systemdiagnostics.See Chapter 5, “Running the System Diagnostics,”in the Installation and Troubleshooting Guide forinformation.Installing DIMMsThe memory module has 32 DIMM sockets arranged infour banks. Install DIMMs consecutively in groups offour starting with socket J2.NOTE: Use only DIMMs approved for use in this system.To install the DIMMs, use the following procedure.1. Remove the memory module as described insteps 1 through 4 of “Performing a MemoryUpgrade” found earlier in this section.2. Place the memory module flat, with the component-side up and the memory module oriented with theedge connectors toward you.3. Install the DIMM by orienting the pin-1 end ofthe DIMM with the pin-1 end of the memorymodule socket (see Figure 1).4. Hold the DIMM at a 90-degree angle to the mem-ory module and press the DIMM carefully into asocket until it is held by the retaining clips.Check for proper installation by ensuring that thereis no gap between the retaining clips and the DIMM.If the DIMM is not properly installed, remove itaccording to the following removal procedure. Thenreinsert the DIMM into the memory module socket.5. Continue with steps 7 through 12 of “Performinga Memory Upgrade” found earlier in this section.Removing DIMMsTo remove the DIMMs, use the following procedure:1. Remove the DIMMs from the memory module bystarting from the highest-numbered socket.2. Open the retaining clips just enough to pull the topedge of the DIMM away from the retaining clips.3. Pull the DIMM away from the socket, and store itproperly.______________________Information in this document is subject to change without notice. 1997–1998 Dell Computer Corporation.
