• 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 configuration 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/--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/--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.

Example:

A:>syscfg --MemTest=Enabled

MemTest=Enabled
