BIOS.SysProfileSettings.MemPatrolScrub (Read or Write)
Description
Patrol Scrubbing searches the memory for errors and repairs correctable errors to prevent the
accumulation of memory errors. When set to Disabled, no patrol scrubbing will occur. When set to
Standard Mode, the entire memory array will be scrubbed once in a 24 hour period. When set to Extended
Mode, the entire memory array will be scrubbed more frequently to further increase system reliability.
Read-only unless System Profile is set to Custom.
Has a dependency on the System Profile. Can only be set if the System Profile is set to Custom. Is set to
Standard if the System Profile is set to Performance Per Watt (DAPC), Performance Per Watt (OS),
Performance Per Watt (HWPM), or Performance. Is set to Extended if the System Profile is set to Dense.

have a negative impact on memory subsystem performance under some circumstances. Read-only unless
