Socket AM5 platform

This GIGABYTE B840 EAGLE WIFI6E board uses the AMD B840 chipset on an ATX form factor. It supports Ryzen 9000, 8000, and 7000 series processors in the AM5 socket. Dual-channel DDR5 memory and a 8+2+2 digital VRM design deliver stable power for gaming and productivity builds.

PCIe 4.0 x16 graphics slot

The single PCIe 4.0 x16 slot determines which graphics card you can install and the bandwidth available. Two PCIe 4.0 M.2 slots and one PCIe 3.0 M.2 slot provide high-speed storage options. The rear I/O includes DisplayPort and HDMI outputs for processors with integrated graphics.

Wi-Fi 6E and 2.5GbE LAN

Onboard Wi-Fi 6E uses the 6 GHz band to reduce congestion, while Bluetooth 5.3 handles peripherals. A 2.5GbE LAN port adds wired throughput. EZ-Latch mechanisms for PCIe and M.2 plus a WIFI EZ-Plug antenna simplify assembly, and Q-Flash Plus updates the BIOS without a CPU or memory installed.

Questions about this item

How much can X3D Turbo Mode lift gaming frame rates on a Ryzen 9000 CPU?

The BIOS feature can raise gaming FPS by up to 18 percent on Ryzen 9000 processors, though the exact gain varies by game.

What practical speed ceiling does the Wi-Fi 6E and 2.5 GbE LAN combination impose?

Wi-Fi 6E adds the 6 GHz band for extra bandwidth and less congestion, while the wired port caps at 2.5 Gbps for high-throughput local traffic.

What clearance and mounting points does the ATX board need inside a case?

It measures 30.5 cm by 24.4 cm and uses the standard ATX screw pattern, so any ATX-compatible chassis with matching standoffs will fit.
