Mode
Sets 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 Mirror
Mode 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 Spare Mode is
enabled, the memory size
reported to the operating
system does not include the
spare portion.
