Mode-specific guidelines
The configurations allowed depend on the memory mode selected in the System BIOS.
Table 43. Memory operating modes
Memory Operating Mode
Description
Optimizer Mode
The
Optimizer Mode
if enabled, the DRAM controllers operate
independently in the 64-bit mode and provide optimized memory
performance.
Mirror Mode
The
Mirror Mode
if enabled, the system maintains two identical
copies of data in memory, and the total available system memory is
one half of the total installed physical memory. Half of the installed
memory is used to mirror the active memory modules. This feature
provides maximum reliability and enables the system to continue
running even during a catastrophic memory failure by switching
over to the mirrored copy. The installation guidelines to enable
Mirror Mode require that the memory modules be identical in size,
speed, and technology, and they must be populated in sets of 6 per
processor.
Single Rank Spare Mode
Single Rank Spare Mode
allocates one rank per channel as a spare.
If excessive correctable errors occur in a rank or channel, while the
operating system is running, they are moved to the spare area to
