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
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.
Data Scrambling
Select Enabled to enable data scrambling to ensure data security and integrity.
The options are Disabled and Enabled.
Device Tagging
Select Enabled to support device tagging. The options are Disabled and
Enabled.
Thermal Throttling
Throttling improves reliability and reduces power consumption in the
processor via automatic voltage control during processor idle states. The
options are Disabled and CLTT (Closed Loop Thermal Throttling).
