NOTE:
Minimum one memory kit per processor must be installed.
It is recommended to install three identical memory kits for triple-channel symmetric memory
configurations to increase memory transfer speed.
Mix configurations of UDIMM/RDIMM are not supported.
Maximum Memory Speed
See the table below for the actual maximum memory transfer speed in Independent Channel / Memory
Sparing Configuration.
DDR3 memory speed depends on the type of DIMMs, the native memory bus speed of the memory
controller and memory configuration. All memory buses operate at the clock frequency of the DIMM with
the lowest frequency.
