Memory As long as no errors have occurred on the memory board, the system periodically switches which set of banks it reads from to be sure that both sets are monitored for memory errors. DIMM Installation Requirements In addition to the DIMM configuration requirements for advanced ECC memory, observe the following DIMM configuration requirements when installing DIMMs for single-board mirrored memory: • Bank C mirrors bank A, and bank D mirrors bank B. Banks A and C must always be populated. • DIMMs in the mirrored banks must be configured identically to the banks they are mirroring. Corresponding banks (for instance, bank A and bank C) must be populated with DIMMs of the same capacity. IMPORTANT: If any one of the above requirements is not met, the system automatically switches to advanced ECC memory and displays an error message during POST. Software The following software components of the memory system provide memory configuration and management capabilities: • ROM-Based Setup Utility (RBSU) • Insight Manager 7 IMPORTANT: The optional online spare memory and single-board mirrored memory features do not require special software drivers and are operating system independent.
