AM5 socket for Ryzen 7000, 8000 and 9000 series

This ATX motherboard uses the AMD B850 chipset and an AM5 socket that accepts Ryzen 7000, 8000 and 9000 series processors. It provides four DDR5 slots with a maximum capacity of 192 GB and supports AMD EXPO profiles for memory overclocking. The board also includes Wi-Fi 6E, 2.5 Gb LAN and rear USB 10 Gbps Type-A and Type-C ports for fast connectivity.

PCIe 5.0 x16 slot and PCIe 5.0 M.2 slot

The primary expansion slot runs at PCIe 5.0 x16 when a Ryzen 7000 or 9000 series CPU is installed, dropping to PCIe 4.0 x16 with an 8000 series chip. The top M.2 socket supports PCIe 5.0 x4 speeds with the same processors, while a second M.2 slot operates at PCIe 4.0 x4. Four SATA 6 Gb/s ports and additional PCIe 3.0 x1 slots complete the storage and add-in card options.

Builders who need PCIe 5.0 graphics

Enthusiasts planning a high-end GPU and the fastest available M.2 drive will benefit from the PCIe 5.0 links on this board. Users staying with PCIe 4.0 components or requiring more than three M.2 sockets should consider alternative models.

Questions about this item

What does the 8000+ MT/s DDR5 rating mean when I install memory?

The board supports DDR5 speeds up to 8000+ MT/s when overclocked via AMD EXPO or ASUS AEMP profiles, running dual-channel across four 288-pin slots with a 192 GB maximum.

How does the PCIe 5.0 x16 slot behave with different Ryzen series?

With Ryzen 9000 or 7000 CPUs the top slot runs at PCIe 5.0 x16; with Ryzen 8000 CPUs it runs at PCIe 4.0 x16 (x8/x4 mode).

What clearance and mounting does the M.2_1 slot need?

M.2_1 accepts 2280 Key M drives and is covered by the onboard M.2 heatsink; it runs PCIe 5.0 x4 with Ryzen 9000 or 7000 and PCIe 4.0 x4 with Ryzen 8000.
