Notes for the configuration of memory mirroring
Even if "Mirrored Memory with Advanced ECC Support" is set in "Advanced Memory Protection" and Memory
Mirroring Configuration is selected, in case DIMM configuration that cannot constitute memory mirroring due
to expansion or removal of DIMM is detected, "Advanced Memory Protection" operates as "Advanced ECC"
configuration.
In this case, POST's "Advanced Memory Protection Mode:" is displayed "Advanced ECC."
IML also records the relevant error events.
Notes for replacements at failure
At the time of failure, identify damaged DIMM from IML and replace DIMM one by one.
