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.
