Installation of Memory Modules
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 EPYC
processor. Based on the guideline, you may adjust your memory configuration
according to your PCIe expansion card configuration.
The motherboard will support odd-numbered modules (1 or 3 modules installed) but
is unable to activate Dual Channel Technology. For great performance, a balanced
memory population is recommended.
