DIMM Installation Rules
At least one DIMM must be configured in slots supported by CPU 1.
Optimal memory performance can be achieved if the processors in a server are
configured with the same number of DIMMs and the DIMMs are evenly
distributed among the memory channels. Unbalanced configuration reduces
memory performance and is not recommended.
In unbalanced DIMM configuration, DIMMs are not evenly configured for memory
channels. If a processor is configured with 3, 5, 7, 9, 10, 11, 12, 13, 14 or 15
DIMMs, the DIMMs are not evenly configured for memory channels.
Memory configuration must comply with the DIMM installation rules. For details,
see the
DIMMs in vacant DIMM slots.
