Overview:
When upgrading memory DIMMs 1A and 3A must match. DIMMs 5B and 7B DIMMs 2C and 4C and DIMMs 6D and 8D must match and must be installed as a pair. When DIMMs 1A and 3A are populated the system is automatically configured for 2:1 interleaving. When all 4 banks are populated the system is automatically configured for 4:1 interleaving. When four six or eight DIMMs are populated with identical DIMMs the system is automatically configured for bank interleaving.

NOTE: In the online spare configuration the ROM automatically configures the last populated bank as the spare memory. If only banks A and B are populated bank B is the spare bank. If banks A B and C are populated bank C is the spare bank Online spare memory is configured through RBSU.

NOTE: Mirrored Memory uses mirrored banks to provide a high level of memory redundancy. Customer chooses to implement or not: User selectable via BIOS and default is off.
