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 | Information | This event is generated when |
detected on Bank # DIMM |
| there is a memory error |
[A/B]. |
| correction on a particular Dual |
|
| Inline Memory Module (DIMM). |
|
|
|
ECC uncorrectable error | Critical | This event is generated when the |
detected on Bank # |
| chipset is unable to correct the |
[DIMM]. |
| memory errors. Usually, a bank |
|
| number is provided and DIMM |
|
| may or may not be identifiable, |
|
| depending on the error. |
|

|
Correctable memory error | Critical | This event is generated when the |
logging disabled. |

|
| correction rate exceeds a |
|
| predefined limit. |

|
|
Persistent correctable | Warning | This event is generated when |
memory errors detected on |
| there is a memory error |
a memory device at |
| correction on a particular Dual |
location(s) <DIMM |
| Inline Memory Module (DIMM). |
number>. |
|
|
Critical | This event is generated when the | |
detected on a memory |
| chipset is unable to correct the |
device at location(s) |
| memory errors. Usually, more |
<location>. |
| than on DIMM is listed because a |
|
| single DIMM may or may not be |
|
| identifiable, depending on the |
|
| error. |
|
|
|
Correctable memory error | Critical | This event is generated when the |
logging disabled for a |
| chipset in the ECC error |
memory device at location |
| correction rate exceeds a |
<location>. |
| predefined limit. |
