System memory Overview This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module (DIMM) sockets. 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. • For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs). • Refer to www.asus.com for the latest Memory QVL (Qualified Vendors List) Recommended memory configurations DIMM_A2* DIMM_A2* DIMM_B2* DIMM_A1 DIMM_A2* DIMM_B1 DIMM_B2* 1-10 Chapter 1: Product introduction
