memory channel. If either of these conditions is
found, correct and retry with the same DIMM.
(Note: Event Log may contain a recent 00580A4
event denoting detected change in DIMM
population that could be related to this problem.)
2. If no problem is observed on the DIMM connectors
or the problem persists, replace the DIMM
identified by LightPath and/or event log entry.
3. If problem re-occurs on the same DIMM connector,
replace the other DIMMs on the same memory
channel.
4. Check IBM support site for an applicable service
bulletin or firmware update that applies to this
memory error.
5. (Trained Service technician only) If problem
re-occurs on the same DIMM connector, inspect
connector for damage. If found, replace system
board.
6. (Trained Service technician only) Replace affected
Processor.
7. (Trained Service technician only) Replace system
board.
S.51006 [S.51006] A memory mismatch has been
detected. Please verify that the memory
configuration is valid.
Explanation: One or More Mismatched DIMMs
Detected
Severity: Error
User response: Complete the following steps:
Could follow an uncorrectable memory error or
1.
failed memory test. Check log and service that
event first. DIMMs disabled by other errors or
actions could cause this event.
Verify that the DIMMs are installed in the correct
2.
population sequence, according to the service
information for this product.
3. Disable memory mirroring and sparing. If this
action eliminates the mismatch, check IBM Support
site for information related to this problem.
4. Reflash UEFI firmware.
Replace DIMM
5.
(Trained Service technician only) Replace Processor.
6.
S.51009 [S.51009] No system memory has been
detected.
Explanation: No Memory Detected
Severity: Error
User response: Complete the following steps:
Make sure that one or more DIMMs are installed in
1.
the server.
If no memory fault is recorded in the logs and no
2.
DIMM connector error LEDs are lit, verify that all

System x3550 M4 Type 7914: Installation and Service Guide
DIMM connectors are enabled using the Setup
utility or the Advanced Settings Utility (ASU).
3. Re-Install all DIMMs verifying the correct
population sequence, according to the service
information for this product.
4. (Trained service technician only) Replace the
processor.
5. (Trained service technician only) Replace the
system board.
S.58008 [S.58008] A DIMM has failed the POST
memory test.
Explanation: DIMM Failed Memory Test
Severity: Error
User response: Complete the following steps:
1. You must AC-cycle the system to re-enable affected
DIMM connector or re-enable manually using F1
setup
2. If the node has been recently installed, serviced,
moved, or upgraded, check to ensure that DIMMs
are firmly seated and that no foreign material can
be seen in the DIMM connector. If either condition
is observed, correct and retry with the same DIMM.
(Note: Event Log may contain a recent 00580A4
event denoting detected change in DIMM
population that could be related to this problem.)
3. If problem persists, replace the DIMM identified by
LightPath and/or event log entry.
4. If problem re-occurs on the same DIMM connector,
swap the other DIMMs on the same memory
channel across channels one at a time to a different
memory channel or Processor. (check service
information for this product/Install guide for
population requirements for sparing/paring
modes). If problem follows a moved DIMM to a
different memory channel, replace that DIMM.
5. Check IBM support site for an applicable service
bulletin or firmware update that applies to this
memory error.
6. (Trained service technician only) If problem stays
with the original DIMM connector, re-inspect DIMM
connector for foreign material and remove, if found.
If connector is damaged, replace system board.
7. (Trained service technician only) Remove affected
Processor and inspect Processor socket pins for
damaged or mis-aligned pins. If damage is found,
or this is an upgrade Processor, replace system
board. If there are multiple Processor's, swap
Processor's to move affected Procesor to another
Processor socket and retry. If problem follows the
affected Processor (or there is only one Processor),
replace the affected Processor.
8. (Trained Service technician only) Replace the
system board.
