Hardware options installation 37
Advanced Memory Protection options are configured in RBSU. If the requested AMP mode is not supported
by the installed DIMM configuration, the node boots in Advanced ECC mode. For more information, see "HP
ROM-Based Setup Utility (on page
48 )."

Advanced ECC memory configuration
Advanced ECC memory is the default memory protection mode for this node. Standard ECC can correct
single-bit memory errors and detect multi-bit memory errors. When multi-bit errors are detected using
Standard ECC, the error is signaled to the node and causes the node to halt.
Advanced ECC protects the node against some multi-bit memory errors. Advanced ECC can correct both
single-bit memory errors and 4-bit memory errors if all failed bits are on the same DRAM device on the DIMM.
Advanced ECC provides additional protection over Standard ECC because it is possible to correct certain
memory errors that would otherwise be uncorrected and result in a node failure. Using HP Advanced
Memory Error Detection technology, the node provides notification when a DIMM is degrading and has a
higher probability of uncorrectable memory error.
General DIMM slot population guidelines
Observe the following guidelines for all AMP modes:
• Install DIMMs only if the corresponding processor is installed.
• When two processors are installed, balance the DIMMs across the two processors.
• White DIMM slots denote the first slot of a channel (Ch 1-A, Ch 2-B).
• When two processors are installed, install the DIMMs in sequential alphabetical order balanced
between the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so on.
For detailed memory configuration rules and guidelines, use the Online DDR3 Memory Configuration Tool
on the HP website ( http://www.hp.com/go/ddr3memory-configurator ).

Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
• Observe the general DIMM slot population guidelines (on page 37 ).
• DIMMs may be installed individually.
