1.4 System memory This motherboard comes with two Double Data Rate 5 (DDR5) Dual Inline Memory Module (DIMM) sockets. The figure illustrates the location of the DDR5 DIMM sockets: DIMM_A DIMM_B Channel Channel A Channel B Sockets DIMM_A DIMM_B A DDR5 memory module is notched differently from a DDR, DDR2, DDR3 or DDR4 module. DO NOT install a DDR, DDR2, DDR3 or DDR4 memory module to the DDR5 slot. • 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. • You may install 8 GB,16 GB, 24 GB, 32 GB, and 48 GB unbuffered, ECC and NonECC DDR5 DIMMs into the DIMM slots. • The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. • For system stability, use a more efficient memory cooling system to support a full memory load. • 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. • Supported memory types, data rate (speed), and number of DRAM modules vary depending on the CPU and memory configuration, for more information please refer to CPU/Memory Support list under the Support tab of product information site or visit https://www.asus.com/support/.
