Patrol Scrub (Available when it is supported by the hardware components)
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 Enable, read-and-write will be performed
every 16K cycles per cache line if there is no delay caused by internal processing.
The options are Enable and Disable.
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 Enable to use Demand Scrubbing for ECC memory correction. The
options are Enable and Disable.
