Memory RAS (Reliability-Availability-Serviceability)
Configuration
Use this submenu to configure the following Memory RAS settings.
Memory RAS Configuration Setup
RAS Mode
When Disable is selected, RAS is not supported. 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
Disable , Mirror, and Lockstep Mode.
Memory Rank Sparing
Select Enabled 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 Enable, read-and-write will be
performed every 16K cycles per cache line if there is no delay caused by internal
processing. 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 to
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 .
