The figure illustrates the location of the DDR4 DIMM sockets: DIMM_A1 DIMM_A2 DIMM_B1 DIMM_B2 Channel Channel A Channel B Sockets DIMM_A1 & DIMM_A2 DIMM_B1 & DIMM_B2 • You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules. • According to Intel® CPU spec, DIMM voltage below 1.35V is recommended to protect the CPU. 1-11 ASUS PRIME H270M-PLUS
