Checking the amount of free space in the memory dump output
destination
Ensure that the output destination of the MEMORY.DMP file has free space
equal to at least the physical memory size plus 400 MB.
Configuring the settings for taking a complete memory dump
A complete memory dump collects information including the user mode. This
is why a complete memory dump provides more possibilities for identifying
the cause when analyzing a failure. Note, however, that a complete memory
dump requires more free space in the output destination according to the
installed physical memory size. If you can ensure sufficient free space for
storing the memory dump file, we recommend taking a complete memory
dump.
Before performing the following procedure, also ensure that the content of
Setting the Windows system environment on page B-2 is also configured in
