MemOpMode or memoperatingmode
Table 58. MemOpMode or memoperatingmode
Valid Arguments
● On systems prior to YX2X: optimizer, mirror, advancedecc
● On YX2X 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
MemOpVoltage or dimmvoltage
Table 59. MemOpVoltage or dimmvoltage
Valid Arguments
● On systems prior to YX2X: auto, 1.5
● On YX2X 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
MemTest or memtest
Table 60. MemTest or memtest
Valid Arguments
● On systems prior to YX2X: enable, disable
● On YX2X and later systems: Enabled, Disabled
Description
Enables or disables the POST extended memory test.
