What a buyer needs to know

Use it for: an AM5 Mini-ITX build that needs DDR5 memory and two M.2 2280 storage slots. This board is in our two Terra proposals. Check before buying: confirm the CPU's required BIOS version, memory support and cooler clearance. ASRock lists two DIMM slots, Wi-Fi 6E and two M.2 2280 slots; storage-link speed depends on the slot and processor. Install the supplied antennas for wireless use. Evidence: the manual specifies the hardware, but does not certify your Linux image, wireless module revision or suspend behavior. Confirm support for your installed module and OS version; keep Ethernet available during setup. Compare current board prices and seller bundle contents instead of choosing solely by chipset name.
