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-C, Ch 3-B, Ch 4-D).
• Do not mix RDIMMs or UDIMMs.
• When one processor is installed, install DIMMs in sequential alphabetic order: A, B, C, D, E, F, and so
forth.
• When two processors are installed, install the DIMMs in sequential alphabetic order balanced between
the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so forth.
• For DIMM spare replacement, install the DIMMs per slot number as instructed by the system software.
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 ).
