Memory RAS (Reliability_Availability_Serviceability) Configuration
Use this submenu to configure the following Memory RAS settings.
Patrol Scrub
Patrol Scrubbing is a process that allows the CPU to correct correctable memory errors
detected on a memory module and send the correction to the requestor (the original
source). When this item is set to Enabled, the IO hub will read and write back one cache
line every 16K cycles, if there is no delay caused by internal processing. By using this
method, roughly 64 GB of memory behind the IO hub will be scrubbed every day. The
options are Enable and Disable.
Patrol Scrub Interval
This feature allows you to decide how many hours the system should wait before the
next complete patrol scrub is performed. Use the keyboard to enter a value from 0-24.
The Default setting is 24.
Demand Scrub
Demand Scrubbing is a process that allows the CPU to correct correctable memory errors
found on a memory module. When the CPU or I/O issues a demand-read command, and
the read data from memory turns out to be a correctable error, the error is corrected and
sent to the requestor (the original source). Memory is updated as well. Select Enable to
use Demand Scrubbing for ECC memory correction. The options are Enable and Disable.
Device Tagging
Select Enable to support device tagging. The options are Disable and Enable.
