Memory problems Memory problems The amount of memory displayed is less than the amount of memory installed. Action The amount of available memory shown might be somewhat less than expected because of basic input/output system (BIOS) shadowing in random access memory (RAM), video takes 1 MB, and ACPI and USB also can take up to 1 MB. Verify that: 1. You have installed the correct type of RIMMs for your computer. See "Working with memory" on page 93 for instructions on adding RIMMs. 2. The RIMMs are properly installed and securely connected. 3. If you added or removed memory, you saved the new configuration before exiting the Configuration/Setup Utility program. 4. All RIMM connectors have either a RIMM or a continuity module installed. 5. You do not have more than 32 devices total on your RIMMs. If the problem persists, run the memory test from the diagnostic program supplied with your computer. (See "IBM Enhanced Diagnostics program" on page 126 for further information.) The system might have detected a bad RIMM and automatically reallocated memory to enable your computer to continue to operate. If you cannot correct the problem, have the computer serviced. 122 PC 300PL User Guide

1.
You have installed the correct type of RIMMs for
your computer.
See “Working with memory” on
page
93 for instructions on adding RIMMs.
2.
The RIMMs are properly installed and securely
connected.
