Message Description Action
S.51003 [S.51003] An
uncorrectable
memory error was
detected in DIMM
slot % on rank %.
[S.51003] An
uncorrectable
memory error was
detected on
processor % channel
%. The failing
DIMM within the
channel could not
be determined.
[S.51003] An
uncorrectable
memory error has
been detected
during POST. Fatal Memory
Error Occurred.
1. Check the IBM support website for an applicable retain tip
or firmware update that applies to this memory error.
2.
If the problem remains, replace the affected DIMMs.
3.
(Trained technician only) If the problem occurs on the same
DIMM connector, check the DIMM connector. If the
connector contains any foreign material or is damaged,
replace the system board (see Removing the system board
and Installing the system board).
4. (Trained technician only) Remove the affected
microprocessor and check the microprocessor socket pins
for any damaged pins. If a damage is found, replace the
system board.
5.
(Trained technician only) Replace the affected
microprocessor (see Removing a microprocessor and heat
sink and Installing a microprocessor and heat sink).
S.51006 [S.51006] A memory
mismatch has been
detected. Please
verify that the
memory
configuration is
valid. One or More
Mismatched
DIMMs
Detected. Note: Each time you install or remove a DIMM, you must
disconnect the server from the power source; then, wait 10
seconds before restarting the server.
1. This could be an uncorrectable memory error or failed
memory test. Check the error log. DIMMs disabled by
other errors or actions could cause this event too.
2.
Make sure that the DIMMs have been installed in the
correct sequence (see Memory module installation).
3. Disable memory mirroring and sparing. If this action
eliminates the mismatch, check IBM support website for
information related to this problem.
4. Refresh the UEFI firmware.
5. Replace the DIMM (see Removing a memory module and
Memory module installation).
6. (Trained technician only) Replace the affected
microprocessor (see Removing a microprocessor and heat
sink and Installing a microprocessor and heat sink).
