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
