via automatic voltage control during processor idle states. The options are
Disabled and CLTT (Closed Loop Thermal Throttling).

BIOS.
Memory RAS (Reliability_Availability_Serviceability)
Confi guration
Use this submenu to confi gure the following Memory RAS settings.
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 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 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.
