mode will only start to work for ADDDC after a faulty DRAM module is spared. The options
are Enable and Disable.
Patrol Scrub
Patrol Scrubbing is a process that allows the CPU to correct correctable memory errors
detected in a memory module and send the corrections to the requestor (the original
source). When this feature 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 Enable and Disable.
Patrol Scrub Interval (Available when Patrol Scrub is set to Enable)
Use this item to specify the number of hours (between 0 to 24) required for the system to
complete a full patrol scrubbing. Enter 0 for patrol scrubbing to be performed automatically.
The default setting is 24.
IIO Configuration
EV DFX (Device Function On-Hide) Features
When this feature is set to Enable, the EV_DFX Lock Bits that are located in a processor
will always remain clear during electric tuning. The options are Disable and Enable.
