Rank Interleaving
This feature selects from the different rank memory interleaving methods. The
options are Auto, 1 Way, 2 Way, 4 Way and 8 Way.
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 North Bridge 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
North Bridge 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.

This feature enables Data Scrambling. The options are Enabled and Disabled.
Device Tagging
