How to use

Install the motherboard into a compatible ATX chassis, connect the Hi‑Density CPU and ATX power connectors, and mount CPU, cooler, memory and storage according to the manufacturer’s instructions. Enable DDR5 XMP or AMD EXPO profiles in BIOS to apply pre‑tested memory overclock settings. For NVMe storage, install PCIe Gen5 or Gen4 M.2 SSDs into the designated M.2 slots and secure the M.2 heatsinks to improve thermal performance. Use the BIOS EZ Flash feature to update firmware via USB if needed. Configure fan curves through ASRock A‑Tuning Fan‑Tastic Tuning and select PWM or DC mode as detected by the fan headers. Connect network devices via onboard Wi‑Fi 6E or the 2.5 Gb/s LAN port and set up audio preferences with Nahimic software where applicable.

Recommendations

Use compatible DDR5 modules that support Intel XMP or AMD EXPO to achieve stable memory overclocking. When installing high-power CPUs or performing heavy overclocking, use a high-quality power supply and ensure good case airflow; secure the reinforced PCIe slot and use the M.2 heatsinks to maintain SSD performance.
