Memory ECC Events
The memory ECC event messages monitor the memory modules in a system. These messages monitor
the ECC memory correction rate and the type of memory events that occurred.
Table 10. Memory ECC Events
Event Message Severity Cause
ECC error correction
detected on Bank # DIMM
[A/B].
Information This event is generated when
there is a memory error
correction on a particular Dual
Inline Memory Module (DIMM).
ECC uncorrectable error
detected on Bank #
[DIMM].
Critical This event is generated when the
chipset is unable to correct the
memory errors. Usually, a bank
number is provided and DIMM
may or may not be identifiable,
depending on the error.
Correctable memory error
logging disabled.
Critical This event is generated when the
chipset in the ECC error
correction rate exceeds a
predefined limit.
Persistent correctable
memory errors detected on
a memory device at
location(s) <DIMM
number>.
Warning This event is generated when
there is a memory error
correction on a particular Dual
Inline Memory Module (DIMM).
Multi-bit memory errors
detected on a memory
device at location(s)
<location>.
Critical This event is generated when the
chipset is unable to correct the
memory errors. Usually, more
than on DIMM is listed because a
single DIMM may or may not be
identifiable, depending on the
error.
Correctable memory error
logging disabled for a
memory device at location
<location>.
Critical This event is generated when the
chipset in the ECC error
correction rate exceeds a
predefined limit.
