Memory Settings details Option System Memory Size System Memory Type System Memory Speed Video Memory System Memory Testing Memory Operating Mode Current State of Memory Operating Mode Fault Resilient Mode Memory Size[%] Node Interleaving ADDDC Setting Description Specifies the size of the system memory. Specifies the type of memory installed in the system. Specifies the speed of the system memory. Specifies the size video memory. Specifies whether the system memory tests are run during system boot. The two options available are Enabled and Disabled. This option is set to Disabled by default. This field selects the memory operating mode. This feature is active only if a valid memory configuration is detected. When Optimizer Mode is enabled, the DRAM controllers operate independently in 64-bit mode and provide optimized memory performance. When Dell Fault Resilient Mode (FRM) is enabled, a percentage of the total installed memory is configured to create a fault resilient zone starting from lowest system memory address for use by select hypervisors for host virtualization resilience. Specify the FRM percentage by using the Fault Resilient Mode Memory Size[%] feature. When Dell NUMA Fault Resilient Mode (FRM) is enabled, a percentage of the installed memory in every NUMA node is configured to create a fault resilient zone for use by select hypervisors for host virtualization resilience. Specify the FRM percentage by using the Fault Resilient Mode Memory Size[%] feature. Specifies the current state of the memory operating mode. Select to define the percent of total memory size that must be used by the fault resilient mode, when selected in the Memory Operating mode. When Fault Resilient Mode is not selected, this option is grayed out and not used by Fault Resilient Mode. Enables or disables the Node interleaving option. Specifies if the NonUniform Memory Architecture (NUMA) is supported. If this field is set to Enabled, memory interleaving is supported if a symmetric memory configuration is installed. If the field is set to Disabled, the system supports NUMA (asymmetric) memory configurations. This option is set to Disabled by default. Enables or disables ADDDC Setting feature.

Specifies the type of memory installed in the system.
System Memory Speed
Specifies the speed of the system memory.
Video Memory
Specifies the size video memory.
System Memory Testing
Specifies whether the system memory tests are run during system boot.
The two options available are
Enabled
and
Disabled
. This option is set to
Disabled
by default.
Memory Operating Mode
This field selects the memory operating mode. This feature is active
only if a valid memory configuration is detected. When
Optimizer Mode
is enabled, the DRAM controllers operate independently in 64-bit mode
and provide optimized memory performance. When
Dell Fault Resilient
Mode (FRM)
is enabled, a percentage of the total installed memory is
configured to create a fault resilient zone starting from lowest system
memory address for use by select hypervisors for host virtualization
resilience. Specify the FRM percentage by using the Fault Resilient
Mode Memory Size[%] feature. When
Dell NUMA Fault Resilient Mode
(FRM)
is enabled, a percentage of the installed memory in every NUMA
node is configured to create a fault resilient zone for use by select
hypervisors for host virtualization resilience. Specify the FRM percentage
by using the Fault Resilient Mode Memory Size[%] feature.
Current State of Memory Operating Mode
Specifies the current state of the memory operating mode.
Fault Resilient Mode Memory Size[%]
Select to define the percent of total memory size that must be used by
the fault resilient mode, when selected in the Memory Operating mode.
When Fault Resilient Mode is not selected, this option is grayed out and
not used by Fault Resilient Mode.
Node Interleaving
Enables or disables the Node interleaving option. Specifies if the 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 the 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
