DIMMs
General DIMM slot population guidelines
Observe the following guidelines for all AMP modes:
• Install DIMMs only if the corresponding processor is installed.
• Do not mix LRDIMMs, UDIMMs, or RDIMMs.
• White DIMM slots denote the first slot of a channel (1-A, 2-B, 3-C).
• 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 forth.
• The minimum DIMM requirement to make this server bootable is one DIMM installed in slot 1-A.
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).
