Displays the amount of video memory utilized.
Specifies whether system memory tests are run during system boot. The
options available are Enabled, Disabled and Hardware Based. By default,
the System Memory Testing option is set to Disabled.
Specifies the memory operating mode. The options available are fault
resilient memory, Optimizer Mode, Advanced ECC Mode, Mirror Mode,
Spare Mode, and Spare with Advanced ECC Mode. By default, the
Memory Operating Mode option is set to Optimizer Mode.
NOTE: The Memory Operating Mode can have different defaults
and available options based on the memory configuration of your
system.
Specifies if Non-Uniform Memory architecture (NUMA) is supported.
Node Interleaving options available are Enabled and Disabled. If this field
is Enabled, memory interleaving is supported if a symmetric memory
configuration is installed. If Disabled, the system supports NUMA
(asymmetric) memory configurations. By default, Node Interleaving
option is set to Disabled.
Specifies the number of DIMM ranks per DDR channel to configure as
spare ranks when Memory Operating Mode is set to Spare Mode or Spare
with Advanced ECC Mode. Spare Ranks per DDR channel options
available are 1 spare rank per DDR channel and 2 spare ranks per DDR
channel. Based on the memory configuration of the system, this option
allows 2 spare ranks per DDR channel. By default, Spare Ranks per DDR
channel option is set to 1 spare rank per DDR channel.
Specifies the memory size to dedicate to Fault Resilient Memory (FRM)
when Memory Operation Mode is set to Fault Resilient Mode. For FRM
mode one memory riser per processor is dedicated for FRM. This option
allows configuring the size of memory dedicated to FRM on each FRM
riser. FRM Redundant Memory Size options are Full Riser, 64GB, and
Half Riser. Half of the FRM size will be reserved for redundancy and not
included in the total system memory size. By default, FRM Redundant
Memory Size option is set to Full Riser.
