Memory Installation

Memory performance is affected by different DIMM configurations. To reach optimal
memory interleaving, be sure to install identical DIMM types with the same size,
speed, and number of ranks on those memory slots corresponding to the correct pro-
cessor.
The following table indicates recommended DIMM configurations with a single pro-
cessor, based on the guideline, you may adjust your memory configuration according
to your PCIe expansion card configuration.
2nd Gen Xeon Scalable (82xx/62xx/52xx/4215) processors support Optane DC per-
sistent memory module (DCPMM).
