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
North Bridge 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 North Bridge will be scrubbed every
day. The options are Enabled and Disabled.
