2.3.1 Overview
The motherboard comes with eight (8) Double Data Rate 4 (DDR4) Dual Inline Memory
Modules (DIMM) sockets.
The figure illustrates the location of the DDR4 DIMM sockets:
2.3.2 Memory Configurations
You may install 16 GB, 32 GB, 64 GB, 128 GB DDR4 RDIMMs into the DIMM sockets using
the memory configurations in this section.
• 6 DIMM configuration is not recommended for AMD EPYC™ 7002 Series processors.
• When mixing 2DPC and 1DPC, ensure that each channel’s total DIMM size should be
equal. The DIMM size of 2DPC should equal to that of 1DPC, for example, if 2DPC is
using a 32GB memory module (32GB * 2), then a 64GB memory module should be
installed for 1DPC.
• All memory modules for 2DPC should be the same.
• Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.
