Patrol Scrub
Patrol Scrubbing is a process that allows the CPU to correct correctable memory
errors detected in a memory module and send the correction to the requestor
(the original source). When this item 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 using this method, roughly 64 GB of memory behind the IO hub
will be scrubbed every day. The options are Enable and Disable.
