Description
Specifies the current version of the system complex programmable
logic device (CPLD) firmware.
Specifies the UEFI compliance level of the system firmware.
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 voltage 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.
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.
Specifies the current state of the memory operating mode.
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.
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 impact the system performance
under certain workloads. This feature is applicable for x4 DIMMs only. This
option is set to Disabled by default.
When option is set to Fast and memory configuration is not changed,
the system uses previously saved memory training parameters to train
the memory subsystems and 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 Enabled, the system performs the force full
memory training steps on every power on and boot time is slowed on
every boot.
This option controls DIMMs slots on the system. This option is set to
Enabled by default. It allows to disable system installed DIMMs.
