sor via automatic voltage control during processor idle states. The options are
Disabled and
CLTT
(Closed Loop Thermal Throttling).
Socket Interleave Below 4GB
Select Enable for the memory above the 4G Address space to be split between
two sockets. The options are Enable and
Disable
.
Channel Interleaving

BIOS.
Memory RAS (Reliability_Availability_Serviceability)
Configuration
Use this submenu to configure 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.
Lockstep x4 DIMMs
Select Enable to enable Lockstep support for x4 DIMM modules. The options

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.
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
Enable
and Disable.
Device Tagging
Select Enable to support device tagging. The options are
Disable
and Enable.
