CLI Guide
• On 12G and later systems: OptimizerMode, SpareMode, MirrorMode, AdvEccMode,
SpareWithAdvEccMode
Description
Selects the memory operating mode. This feature is active only if a valid memory
conguration is detected. When OptimizerMode is enabled, the DRAM controllers
operate independently in 64-bit mode and provide optimized memory performance. When
MirrorMode is enabled, only half of the installed memory is reported as available to the
operating system. When
AdvECCMode is enabled, the two DRAM controllers are combined
in 128-bit mode to provide optimized reliability. Memory that cannot be teamed by the
controllers is not reported to the operating system. When SpareMode is enabled, the
memory size reported to the operating system does not include the spare portion.
Example:
A:>syscfg --memoperatingmode=optimizer
memoperatingmode=optimizer
Applicable Systems PowerEdge 11G and later systems
MemOpVoltage or dimmvoltage
Table 73. MemOpVoltage or dimmvoltage
Valid Arguments
• On systems prior to 12G: auto, 1.5
• On 12G and later systems: AutoVolt, Volt15V
Description
Sets the DIMM voltage selection. When set to AutoVolt(default value), the system
automatically sets the voltage to the optimal setting based upon the DIMM capability and
the installed DIMM population. This option also enables setting the system DIMM voltage to
a higher (1.5V) setting if the DIMMs support multiple voltages and have been set to a lower
voltage.
NOTE: Volt15V represents 1.5 Volt.
Example:
A:>syscfg --dimmvoltage=auto
dimmvoltage=auto
Applicable Systems PowerEdge 12G and later systems.
MemTest or memtest
Table 74. MemTest or memtest
Valid Arguments
• On systems prior to 12G: enable, disable
• On 12G and later systems: Enabled, Disabled
Description
Enables or disables the POST extended memory test.
