Processor and Chipset Platform

The AM5 socket and AMD B850 chipset support compatible AMD Ryzen processors. CPU compatibility can depend on the installed BIOS revision, so the processor support list should be checked when combining the board with a newly released CPU.

Memory Support

The board provides 4 DDR5 DIMM slots in a dual-channel configuration, supporting up to 256GB. Listed memory capability reaches Up to DDR5-8200 OC. Actual available speeds depend on the installed processor, memory kit, BIOS and selected XMP or EXPO profile.

PCI Express Expansion

1 x PCIe 5.0 x16, 1 x PCIe 4.0 x16 and 1 x PCIe 4.0 x1. This provides a suitable connection for a compatible graphics card while additional slots can support expansion hardware such as capture, sound or networking cards where the board layout allows.

Fast M.2 and SATA Storage

1 x PCIe 5.0 M.2 and 1 x PCIe 4.0 M.2. The board also includes 4 SATA 6Gb/s ports for compatible 2.5 inch SSDs, hard drives and other SATA devices. RAID support for compatible SATA and NVMe storage

Networking and Wireless Connectivity

Wired networking is provided by Realtek 5Gb Ethernet. The integrated Wi-Fi 7 and Bluetooth 5.4 connections support cable-free networking and compatible wireless peripherals.

Audio and Display Connectivity

Realtek ALC897 7.1-channel audio provides onboard sound for speakers, headsets and gaming audio. Any HDMI or DisplayPort connections on the motherboard require a processor with compatible integrated graphics and do not operate from a CPU that has no integrated display capability.

Cooling, RGB and PC Building Features

Flash BIOS, Clear CMOS, EZ M.2 Shield Frozr II, EZ PCIe Clip II and 5Gb networking. 3 x Addressable V2 and 1 x RGB header. Fan headers and UEFI control options allow compatible case fans and CPU cooling hardware to be configured for balanced temperatures and acoustics.
