Memory problems
The amount of memory
displayed is less than the
amount of memory
installed.
40 IBM PC User Guide
Action
The amount of available memory shown might
be somewhat less than expected because basic
input/output system (BIOS) shadowing takes
some random access memory (RAM) and ACPI
and USB can take up to 1MB.
In addition, this system features an integrated
video system in which some memory is used by
the video controller. Windows will only report
the memory available for its use. For example, if
the system uses 4MB of memory for video and
the total system memory is 64MB, Windows will
report 60MB.
Verify that:
1. You have installed the correct type of
DIMMs for your computer. See "Working
with memory" on page 23 for instructions
on adding DIMMs.
2. The DIMMs 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.
The system might have detected a bad DIMM
and automatically reallocated memory to enable
your computer to continue to operate.
If this does not correct the problem, contact IBM
technical support.
