Installing System Components
Memory Mirroring Support
The system supports memory mirroring if eight or twelve identical memory
modules are installed in the system. Mirroring must be enabled in the System
Setup program and can be used only if memory sparing is not enabled. In a
mirrored configuration, the total available system memory is one-half of the
total installed memory.
