AMD B840 Micro ATX Board

This GIGABYTE B840M AORUS ELITE motherboard targets builders who want a compact AM5 platform with WiFi6E and high-speed DDR5 support. It fits Micro ATX cases while still providing four DDR5 slots and modern connectivity.

Upgrade from B550 or older AM4

Moving from an AMD B550 or earlier AM4 board lets you run Ryzen 7000, 8000 and 9000 series processors with DDR5 memory up to 8200 MT/s overclocked. The jump is worth it when you need PCIe 5.0 graphics bandwidth and integrated Radeon graphics with DisplayPort 1.4 at 3840x2160 resolution.

Straightforward AM5 install

The AM5 socket uses a land-grid array so there are no fragile pins on the CPU; align the triangle markers and lower the retention lever. Common issues are forgetting the BIOS update for newer Ryzen 9000 chips and not seating DDR5 modules until the latches click on both ends.

Questions about this item

What size case and mounting holes does the Micro ATX board need?

The board uses the Micro ATX form factor, so it fits any case with Micro ATX or larger motherboard trays and standard ATX mounting holes.

How do I install the DDR5 memory and which slot order avoids the common mistake?

Install modules in the two grey slots first for dual-channel operation; the board has four 288-pin DDR5 slots supporting up to 256 GB total.

When will the WiFi 6E module need attention or replacement?

The onboard WiFi 6E is soldered to the board and has no user-serviceable parts; if it fails the motherboard would require professional repair.
