Cause / Actions
Correct the data in memory
and to the requestor.
Correct the data in memory
and to the requestor.
Correct the data in the spare
DIMM or the off-line branch.
Correct the data in memory.
Drop. If sync was issued to
prepare a fast reset for alert
recovery then replay any
queued configuration
command destined for an
alerting DIMM or a DIMM with
a corrupted status CRC.
WARNING: Possible double
DIMM configuration
command execution may
incur undesirable side-
effects.
Successive correction
attempts performed by
software.
