Option
Description
System Memory
Specifies whether the system memory tests are run during system boot. Options are Enabled and
Testing
Disabled. This option is set to Disabled by default.
Dram Refresh
By enabling the CPU memory controller to delay running the REFRESH commands, you can improve
Delay
the performance for some workloads. By minimizing the delay time, it is ensured that the memory
controller runs the REFRESH command at regular intervals. For lntel-based servers, this setting only
affects systems configured with DIMMs which use 8 Gb density DRAMS.
Memory
Specifies the memory operating mode. The options available are Optimizer Mode, Single Rank Spare
Operating Mode
Mode, Multi Rank Spare Mode, Mirror Mode, and Dell Fault Resilient Mode. This option is set to
Optimizer Mode by default.
Current State of
Specifies the current state of the memory operating mode.
Memory
Operating Mode
Node Interleaving Specifies if Non-Uniform Memory Architecture (NUMA) is supported. If this field is set to Enabled,
memory interleaving is supported if a symmetric memory configuration is installed. If this field is set to
Disabled, the system supports NUMA (asymmetric) memory configurations. This option is set to
Disabled by default.
ADDDC Setting
Enables or disables ADDDC Setting feature. When Adaptive Double DRAM Device Correction (ADDDC)
is enabled, failing DRAMs are dynamically mapped out. When set to Enabled it can have some impact to
system performance under certain workloads. This feature is applicable for x4 DIMMs only. This option is
set to Enabled by default.
Opportunistic
Enables or disables opportunistic self-refresh feature. This option is set to Disabled by default and is not
Self-Refresh
supported when DCPMMs are in the system.
Persistent
This field controls Persistent Memory on the system. This option is only available if the persistent memory
Memory
module is installed in the system.
Persistent Memory details
About this task
The Persistent Memory screen details can be found in the NVDIMM-N User Guide and DCPMM User Guideat

Processor Settings
You can use the Processor Settings screen to view the processor settings and perform specific functions such as enabling
virtualization technology, hardware prefetcher, logical processor idling.
Viewing Processor Settings
To view the Processor Settings screen, perform the following steps:
Steps
1. Power on, or restart your system.
NOTE:
The Memory Operating Mode option can have different default and available options based
on the memory configuration of your system.
NOTE:
The Dell Fault Resilient Mode option establishes an area of memory that is fault resilient.
This mode can be used by an operating system that supports the feature to load critical applications
or enables the operating system kernel to maximize system availability.
NOTE:
Only Optimizer Mode should be selected when Intel DC Optane Persistent Memory is
installed.
