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.

Demand Scrub

Demand Scrubbing is a process that allows the CPU to correct correctable
memory errors found on a memory module. When the CPU or I/O issues
a demand-read command, and the read data from memory turns out to
be a correctable error, the error is corrected and sent to the requestor
(the original source). Memory is updated as well. Select Enabled to use
Demand Scrubbing for ECC memory correction. The options are Enabled
and Disabled.
