Patrol Scrubbing is a process that allows the CPU to correct correctable memory errors
detected in a memory module and send the corrections 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
