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.
