How to use

Install a compatible 3rd Generation AMD Ryzen CPU into the Socket AM4, fit DDR4 DIMMs into the memory slots, and mount the motherboard in an ATX case. Connect power from a compatible PSU to the 24-pin ATX and CPU power headers, attach storage devices to the M.2 and SATA connectors, and install graphics cards into the PCIe slots if required. Use the UEFI BIOS and ASUS software utilities to configure memory, storage RAID and fan profiles, and apply performance tuning settings.

Recommendations

For stable operation under heavy workloads, ensure adequate case airflow and attach system fans to the motherboard’s hybrid headers. Use quality thermal paste and verify VRM heatsinks and thermal pads are properly seated. For best storage performance, install NVMe SSDs in the PCIe 4.0 M.2 slot and configure RAID through the BIOS if required.
