Link L1 Enable
Select Enable for Link L1 support to reduce power consumption. The options
are Enable and Disable.
COD Enable (Available when the OS and the CPU support this feature)
Select Enable for Cluster-On-Die support to enhance system performance in
cloud computing. The options are Enable and Disable.
Early Snoop (Available when the OS and the CPU support this feature)
Select Enable for Early Snoop support to enhance system performance. The
options are Enable, Disable, and Auto.
Isoc Mode
Select Enable for Isochronous support to meet QoS (Quality of Service) require-
ments. This feature is especially important for Intel Virtualization Technology. The
options are Enable and Disable.
Memory Configuration
This submenu allows the user to configure Integrated Memory Controller (IMC)
settings.
Enforce POR
Select Enabled to enforce POR restrictions on DDR4 frequency and voltage
programming. The options are Enabled and Disabled.
Memory Frequency
Use this feature to set the maximum memory frequency for onboard memory
modules. The options are Auto, 1333, 1400, 1600, 1800, 1867, 2000, 2133,
2200, 2400, 2600, 2667, 2800, 2993, 3000, 3200, and Reserved (Do not select
Reserved).
Data Scrambling
Select Enabled to enable data scrambling to enhance system performance and
data integrity. The options are Auto, Disabled and Enabled.
DRAM RAPL (Running Average Power Limit) Baseline
Use this feature to set the run-time power-limit baseline for DRAM modules. The
options are Disable, DRAM RAPL Mode 0, and DRAM RAPL Mode 1.

Set Throttling Mode
Throttling improves CPU reliability and reduces power consumption via automat-
ic-voltage control during CPU 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.
A7 Mode
Select Enable to support the A7 (Addressing) mode to improve memory perfor-
mance. The options are Enable and Disable.
DIMM Information
This item displays the status of a DIMM module as detected by the AMI
BIOS.
•
P1 DIMMA1
•
P2 DIMME1
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.
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.
