Memory options
This server contains eight FBDIMM slots. You can expand server memory by installing supported
Registered DDR-2 FBDIMMs.
Memory configurations
The server supports the following Advanced Memory Protection (AMP) options to optimize server
availability.
• Advanced ECC supporting up to 16 GB of active memory using 2-GB FBDIMMs.
• Online Spare Memory providing additional protection against degrading FBDIMMs supporting up to
12 GB of active memory and 4 GB of online spare memory utilizing 2-GB FBDIMMs.
• Mirrored Memory providing protection against failed FBDIMMs supporting up to 8 GB of active
memory and 8 GB of mirrored memory utilizing 2-GB FBDIMMs.
Maximum memory capacities for all AMP modes will increase with the availability of 4-GB FBDIMMs,
including a maximum of 32 GB in Advanced ECC mode. For the latest memory configuration information,
refer to the QuickSpecs on the HP website ( http://www.hp.com ).
The Advanced Memory Protection option is configured in RBSU. By default, the server is set to Advanced
ECC mode. For more information, refer to HP ROM-Based Setup Utility (on page 45 ). If the configured
AMP mode is not supported by the installed FBDIMM configuration, the system boots in Advanced ECC
mode.
The following configuration requirements apply to all AMP modes:
• FBDIMMS must be ECC Registered DDR-2 SDRAM FBDIMMs.
• FBDIMMs must be installed in pairs.
• FBDIMM pairs in a memory bank must have identical HP part numbers.
• FBDIMMS must be populated as specified for each AMP memory mode.
