Patrol Scrub
Patrol Scrub 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 feature is set to Enable, the IO hub will read and write back one
cache line every 16K cycles if there is no delay caused by internal processing. By us-
ing this method, roughly 64 GB of memory behind the IO hub will be scrubbed every
day. The options are Disable and Enable.
*If the feature above is set to Enable, Patrol Scrub Interval will be available for
configuration:
