416473-001 HP 4GB PC2-5300 SDRAM Module

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.
