f. mirroring
The system supports memory mirroring if identical memory modules are installed in the two channels
closest to the processor (memory is not installed in the farthest channel). Mirroring must be enabled in
the System Setup program. In a mirrored configuration, the total available system memory is one-half of
the total installed physical memory.
G. advanced ecc (lockstep) modes
In this configuration, the two channels closest to the processor are combined to form one 128-bit channel.
This mode supports Single Device Data Correction (SDDC) for both x4- and x8-based memory modules.
Memory modules must be identical in size, speed, and technology in corresponding slots.
h. Optimizer (independent channel) mode
In this mode, all three channels are populated with identical memory modules. This mode permits a larger
total memory capacity but does not support SDDC with x8-based memory modules. A minimal single-
channel configuration of 1GB memory modules per processor is also supported in this mode.
