Ryzen 5000-Ready B550 ATX Board

This ATX motherboard uses the AMD B550 chipset and AM4 socket. It supports Ryzen 5000 series CPUs after a BIOS update, plus 3rd Gen Ryzen and 3rd Gen Ryzen with Radeon Graphics. Four DDR4 slots accept up to 128 GB in dual-channel mode. PCIe 4.0 x16 from the CPU and two M.2 slots with thermal guards target builders who want current-gen storage and GPU bandwidth.

Verify BIOS, Memory and Cooler Clearance

Check the vendor CPU-support list for the exact BIOS revision required by your chosen Ryzen 5000 processor. Confirm your DDR4 kit appears on the qualified vendor list for speeds up to 4733 MHz O.C. Ensure your CPU cooler fits the 12+2 phase 50 A DrMOS VRM heatsink layout and does not overhang the first DIMM slot or the primary M.2 heatsink.

Dual M.2, 2.5 GbE LAN, Wi-Fi 6, Front USB-C

The primary M.2 connects via CPU PCIe 4.0 x4 and the second via chipset PCIe 3.0 x4, both with thermal guards. A 2.5 GbE port and Intel Wi-Fi 6 802.11ax handle networking. Front-panel USB 3.2 Gen 2 Type-C, four SATA 6 Gb/s, Realtek ALC1200 audio, DisplayPort 1.4 and HDMI outputs complete the I/O.

Questions about this item

Will a Ryzen 5000 CPU work out of the box or do I need to flash the BIOS first?

The board requires a BIOS update for Ryzen 5000 series processors. If you do not have an older AM4 CPU to perform the update, use the Q-Flash Plus feature with a USB drive and the latest file from the manufacturer website.

Which M.2 slot gives PCIe 4.0 speeds for my NVMe drive?

The top M.2 connector (M2A_CPU) is wired to the CPU and supports PCIe 4.0 x4 with 3rd Gen Ryzen or Ryzen 5000 chips. The second slot runs at PCIe 3.0 x4 from the chipset.

Can I run four sticks of DDR4 at 3600 MHz on this board?

The memory QVL lists validated kits up to DDR4 4400 (OC) on 3rd Gen Ryzen. Four DIMMs at 3600 MHz is a common stable configuration, but final compatibility depends on the CPU memory controller and the specific kit.
