Patrol Scrub Enable
Patrol Scrubbing is a process that allows the CPU to correct correctable memory errors
detected in a memory module and send the correction 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 options are Enabled
and Disabled.
Patrol Scrub Period
Use this feature to select the Patrol Scrub period. The options are 24 hours, 10 hours, 4
hours, and 1 hour.
Demand Scrub Enable
Demand Scrubbing is a process that allows the CPU to correct correctable memory errors
found in 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 corrected as well. Select Enable to
use Demand Scrubbing for ECC memory correction. The options are Enabled and Disabled.
