Option Description
System Memory Size Specifies the size of the system memory.
System Memory Type Specifies the type of memory that is installed in the system.
System Memory Speed Specifies the speed of the system memory.
Video Memory Specifies the size of 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 Specifies the memory operating mode. The option is available and is set
to Optimizer Mode, by default. Options such as Fault Resilient Mode and
NUMA Fault Resilient Mode are available for support when the Advanced
RAS capability processor is installed on the system.
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. Option is displayed when 8 DIMMs are
installed on the sled.
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 the ADDDC Setting feature. When Adaptive Double
DRAM Device Correction (ADDDC) is enabled, failing DRAMs are
dynamically mapped out. When set to Enabled it can impact the system
performance under certain workloads. This feature is applicable for x4
DIMMs only. This option is set to
Enabled by default.
Memory Training When the option is set to Fast and memory configuration is not changed,
the system uses previously saved memory training parameters to train the
memory subsystems. The system boot time is also reduced. If memory
configuration is changed, the system automatically enables Retrain at
Next Boot to force one-time full memory training steps, and then go back
to
Fast afterward.
When option is set to Retrain at Next Boot, the system performs the
force one-time full memory training steps at next power on and boot time
is slowed on next boot.
When option is set to Enable, the system performs the force full
memory training steps on every power on and boot time is slowed on
every boot.
DIMM Self Healing (Post Package Repair) on
Uncorrectable Memory Error
Enables or disables Post Package Repair (PPR) on uncorrectable memory
error. This option is set to Enabled by default.
Correctable Error Logging Enables or disables correctable error logging. This option is set to
Disabled by default.
Memory Paging Policy This field sets memory paging policy.
