The operating memory speed is a function of the rated DIMM speed, DIMMs installed per channel, processor model, and the speed selected in the BIOS/Platform Configuration (RBSU) of the UEFI System Utilities.
Depending on the processor model, the number of DIMMs installed, and whether LRDIMMs or RDIMMs are installed, the memory clock speed can be reduced to 1866 MT/s.
Maximum memory capacity
The maximum memory capacity is a function of the DIMM capacity, number of installed DIMMs, memory type, and number of installed processors.
