Socket AM5 DDR5 Platform

The B840M GAMING PLUS WIFI6E is an AMD AM5 micro-ATX motherboard built for Ryzen 9000, 8000 and 7000 series processors. It delivers an 8+2+2 digital VRM on a 6-layer PCB to keep power delivery stable under load. Four 288-pin slots support up to 256 GB of DDR5 6400 with AMD EXPO profiles for straightforward memory tuning.

Build Integration Essentials

A single PCIe 4.0 x16 slot with reinforced UD latch handles the graphics card while two CPU-sourced M.2 sockets accept 2280 or 2260 drives at PCIe 4.0 x4 speeds. Four SATA 6Gb/s ports and RAID 0/1/10 cover additional storage. Rear I/O supplies USB 3.2 Gen 2 Type-A, USB 3.2 Gen 1 Type-A and Type-C plus a front-panel USB 3.2 Gen 1 Type-C header for case connectivity.

EZ-Latch And Wireless Suite

PCIe EZ-Latch releases the graphics card with one click and M.2 EZ-Latch secures drives without screws. WIFI EZ-Plug simplifies antenna attachment for the onboard Wi-Fi 6E and Bluetooth 5.3 module. The integrated I/O shield speeds assembly and the BIOS adds X3D Turbo Mode for one-click gaming optimisation on compatible Ryzen CPUs.

Questions about this item

How does the 8+2+2 VRM handle heat during sustained loads?

The 8+2+2 digital VRM uses advanced heatsinks on a six-layer PCB to dissipate heat and keep power delivery stable under continuous use.

What noise or thermal output should I expect from the board itself when running all day?

The motherboard is passively cooled with VRM heatsinks and an integrated I/O shield, so it adds no fan noise and minimal heat to the chassis.

Which DDR5 memory kit do I need to have ready for this board to post?

You need unbuffered non-ECC DDR5 DIMMs; the board supports up to 256 GB across four slots at 6400 MT/s with AMD EXPO profiles.
