How to use
Install the motherboard into a compatible micro ATX case, mount an AM5 CPU and apply an appropriate cooler to the CPU socket. Insert DDR5 modules into the two DIMM slots, connect storage devices to the M.2 slots or SATA ports, and attach power using the 24‑pin ATX and hi‑density CPU power connectors. Connect front-panel headers, USB Type‑C front header if applicable, and install the latest BIOS via BIOS Flashback or update through the UEFI. Finally, install the operating system and ASRock drivers; the preinstalled LAN driver eases initial driver installation.
Usage recommendations
For stable memory overclocking, use DDR5 modules with Intel XMP or AMD EXPO profiles and enable the corresponding profile in UEFI. Ensure adequate cooling for the VRM and M.2 areas when using high‑power CPUs or PCIe Gen5 SSDs, and update the BIOS to the latest version before first use to maximize compatibility with newer Ryzen processors.
