How to use

Install the motherboard into a compatible Micro ATX chassis and fit an AM4 processor, CPU cooler, and DDR4 memory modules according to the manual. Connect storage devices to the M.2 slot(s) or SATAIII ports and attach graphics and expansion cards to the PCIe slots as required. Hook up power connectors from the PSU, connect front-panel headers, USB and audio cables, and attach an HDMI cable to the onboard HDMI port for video output. Enter the UEFI BIOS on first boot to configure boot order, memory settings and enable or adjust A.I TP and A.I FAN controls if needed. Use BIO-Flasher or Smart Update to apply BIOS and driver updates.

Recommendations

For optimal performance, use a PCIe 4.0-capable Ryzen processor and PCIe 4.0 NVMe SSD to take full advantage of M.2 bandwidth, populate memory channels in pairs for best DDR4 performance, keep BIOS and drivers up to date using BIO-Flasher or Smart Update, and ensure adequate case airflow when overclocking or running high-load tasks.
