memory module can reach 2933 MT/s. If the Skylake processor is used, the
maximum operating speed of a memory module can reach 2666 MT/s only.
Observe the following when configuring DDR4 memory modules:
– Install memory modules only when corresponding processors are
installed.
– Do not install LRDIMMs and RDIMMs in the same server.
– Install filler memory modules in vacant slots.
Observe the following when configuring DDR4 memory modules in specific
operating mode:
– Memory sparing mode
▪
Comply with the general installation guidelines.
▪
Each memory channel must have a valid online spare configuration.
