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.
