memory mirroring due to expansion or removal of DIMM is detected, "Advanced Memory Protection"
operates as "Advanced ECC" configuration.
In this case,"Advanced ECC" is displayed in POST’s "Advanced Memory Protection Mode".

At the time of failure, identify damaged DIMM(s) from IML and replace DIMM(s) one by one.
