YSTEM 6048R-E1CR60N/L User's Manual
Isoc Mode
Select Enable for Isochronous support to meet QoS (Quality of Service) require-
ments. This feature is especially important for Intel's 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, and 2400.
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).
A7 Mode
Select Enable to support A7 (Addressing) mode to improve memory performance.
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 DIMMH3

Memory RAS (Reliability_Availability_Serviceability) Configuration
Use this submenu to configure the following Memory RAS settings.
RAS Mode
When Independent is selected, all memory modules 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 corrections 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.
