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.
