Memory RAS (Reliability Availability Serviceability) Conguration
Use this submenu to congure the following Memory RAS settings.
RAS Mode
When Independent is selected, all the memory channels operate independently. When
Mirror is selected, the motherboard maintains two identical copies of all data in memory for
data backup. When Lockstep is selected, the motherboard uses two areas of memory to run
the same set of operations in parallel to boost performance. The options are Independent,
Mirror, and Lockstep Mode.
Memory Rank Sparing
Select Enable to enable memory-sparing support for memory ranks to improve memory
performance. The options are Disabled and Enabled.
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 Disable
and Enable.
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 Disable and Enable.
Device Tagging
Select Enable to support device tagging. The options are Disable and Enable.
