Choose the Processor and BIOS Together

The AM5 socket supports AMD Ryzen 7000, 8000 and 9000 Series desktop processors, subject to the exact CPU-support list and required BIOS update. Check the exact CPU entry and required firmware before assembly or an upgrade. The main graphics connection supports up to PCIe 4.0 x16. The usable lane arrangement depends on the installed Ryzen model, so check its configuration when planning the graphics card and other expansion devices.

Four Slots for DDR5 Memory

Four DDR5 DIMM slots support dual-channel memory and AMD EXPO. Memory-kit support and available profile speeds depend on the processor, module layout and installed BIOS. Check MSI’s memory compatibility list for the intended kit. Select the memory with the board and processor as one platform, allowing room around the CPU cooler and DIMM positions. A memory profile is an optional configured setting; it does not guarantee that every combination of modules and processor will reach the same speed.

Map the Storage Connections

2 M.2 slots support PCIe 4.0 x4 storage. M2_2 is unavailable with Ryzen 8500 and 8300 Series processors. The supported slot configuration therefore needs to be checked against the exact processor chosen. Six SATA 6Gb/s ports also support suitable internal drives. SATA_A1 and SATA_A2 do not support RAID. CPU choice affects available CPU-side lanes. Plan the locations before installing the operating-system drive, additional SSDs and other expansion devices so the completed machine uses the connections intended for each component.

Wired and Wireless Connections

Realtek 2.5Gbps LAN supplies the wired network connection. Wi-Fi 6E and Bluetooth provide wireless connections. Access to the 6 GHz band depends on operating-system support and local regulations. The speed reached in use also depends on the router or switch, the network path and the available service. Place the system and its network connections around a stable desk arrangement for the intended workload.

Rear USB, Display and Audio

The rear panel includes 4 × USB 5Gbps Type-A, 3 × USB 10Gbps Type-A and 1 × USB 20Gbps Type-C. HDMI and DisplayPort provide motherboard display connections when the installed processor has integrated graphics; they cannot provide an image from a CPU without graphics. Realtek ALC4080; optical S/PDIF handles onboard audio. Match external drives, monitors and audio equipment to the specific connection and function each device requires.

Which processors does it support?

AMD Ryzen 7000, 8000 and 9000 Series desktop processors, subject to the exact CPU-support list and required BIOS update. Match the exact CPU and required BIOS before installation.

Which memory generation does it use?

It uses DDR5 DIMMs in four slots. Memory is purchased separately; kit compatibility and configured speed depend on the CPU and BIOS.

How are the M.2 slots configured?

2 M.2 slots support PCIe 4.0 x4 storage. M2_2 is unavailable with Ryzen 8500 and 8300 Series processors. The supported slot configuration therefore needs to be checked against the exact processor chosen. SATA_A1 and SATA_A2 do not support RAID. CPU choice affects available CPU-side lanes.

Does the motherboard include wireless networking?

Wi-Fi 6E and Bluetooth provide wireless connections. Access to the 6 GHz band depends on operating-system support and local regulations.

Will HDMI work with every supported CPU?

No. The HDMI and DisplayPort connections require a processor with integrated graphics.

What case size is required?

A case supporting its Micro-ATX mounting layout and 244 × 244 mm board dimensions.
