8. Turn off the server and disconnect it
from the power source.
9. Remove all memory cards and
DIMMs.

configuration for the server (see
Replacing a DIMM and Replacing
the memory card ). To determine the
minimum memory configuration for
your server, see Solving
undetermined problems.
11. Reconnect the server to the power
source and turn on the server.
12. Make sure that the reported
memory size is the same as the
installed memory size.
13. Run the test again. If the memory
passes the test, one of the
uninstalled memory cards or DIMMs
is the failing component.
14. Repeat the steps to remove all
memory cards and DIMMs as
necessary, using different memory
cards and DIMMs to isolate the
failing component. Change only one
component each time to identify the
specific cause of the error.
15. Replace the failing memory card or
DIMM.
