Socket AM5 platform for Ryzen 7000 and 8000 series

This ATX board uses the AMD B650 chipset and the AM5 LGA 1718 socket to support Ryzen 7000 and 8000 series processors. Four 288-pin DDR5 slots accept up to 192 GB of non-ECC un-buffered memory in dual-channel mode. The 6+2+2 phase digital VRM is built for stable power delivery with current CPUs.

PCIe 5.0 M.2 from the CPU and PCIe 4.0 from the

The top M.2 socket runs at PCIe 5.0 x4 with Ryzen 7000 chips and at PCIe 4.0 x4 with Ryzen 8000 Phoenix parts. Two additional chipset M.2 slots and four SATA 6 Gb/s ports provide further storage. USB 3.2 Gen 2x2 Type-C delivers 20 Gb/s, while 2.5 GbE LAN and Wi-Fi 6E handle networking.

Tool-free PCIe release and CPU-less BIOS updates

The primary PCIe x16 slot has a quick-release latch so a graphics card can be removed without tools. Q-Flash Plus lets you flash the BIOS using only a USB drive and standby power, no CPU or memory installed. Smart Fan 6 offers hybrid headers with fan-stop and multiple temperature sources for quiet cooling.

Questions about this item

Will my Ryzen 7000 CPU work with the PCIe 5.0 M.2 slot?

Yes, Ryzen 7000 processors enable PCIe 5.0 x4 or x2 speeds on the primary M.2 connector, while Ryzen 8000 Phoenix 1 CPUs run it at PCIe 4.0 x4.

Can I install four DDR5 DIMMs and reach 7600 MT/s?

The board supports up to 192 GB across four slots; 7600 MT/s is listed as an overclocked speed and stability with four modules depends on the memory kit and CPU memory controller.

Does the rear I/O include a 2.5 GbE port and Wi-Fi 6E?

Yes, the motherboard provides a 2.5 GbE LAN jack and onboard Wi-Fi 6E (802.11ac) with Bluetooth, so no extra network card is required.
