Comments:
Only speeds that are legitimate are available, that is, the user can only specify speeds less than or
equal to the auto-selected Memory Operating Speed. The default Auto setting will select the
highest achievable Memory Operating Speed consistent with the DIMMs and processors
installed.
6. Patrol Scrub
Option Values:
Help Text:
When enabled, performs periodic checks on memory cells and proactively walks through
populated memory space, to seek and correct soft ECC errors.
Comments:
in a 24-hour period, correcting any Correctable ECC Errors it encounters by writing back the
corrected data to memory.
7. Demand Scrub
Option Values:
Help Text:
When enabled, executes when an ECC error is encountered during a normal read/write
of data and corrects that data.
Comments:
Error encountered during a fetch from memory by writing back the corrected data to memory.
8. Correctable Error Threshold
Option Values:
Help Text:
Threshold value for logging Correctable Errors (CE) – Threshold of 10 (default) logs
10th CE, "All" logs every CE and "None"' means no CE logging. All and None are not
valid with Rank Sparing.
Comments:
logging of a SEL Correctable Error Event. Only the first threshold crossing is logged, unless
"All" is selected. "All" causes every CE that occurs to be logged. "None" suppresses CE logging
completely.
When Rank Sparing RAS Mode is configured, "All" and "None" are not valid, so they will not be
presented as choices.
This threshold is applied on a per-rank basis. The Correctable Error occurrences are counted for
each memory rank. When any one rank accumulates a CE count equal to the CE Threshold, then
a single CE SEL Event is logged, and all further CE logging is suppressed.
