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 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 Enable and
Disable
.
Patrol Scrub Interval
This feature allows you to decide how many hours the system should wait before
the next complete patrol scrub is performed. Use the keyboard to enter a value
from 0-24. The Default setting is 24 .
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.
Device Tagging
Select Enable to support device tagging. The options are Disable and Enable.
