GIGABYTE B840M Eagle Wifi6 AMD Motherboard

The GIGABYTE B840M Eagle WiFi 6 is a Micro ATX motherboard built on the AMD B840 chipset and the AM5 socket platform, designed to pair with AMD Ryzen 7000, 8000, and 9000 Series processors. Its compact 24.4 cm x 24.4 cm footprint makes it an efficient choice for space-conscious builds without sacrificing connectivity or expandability. Memory support is a clear highlight: two DDR5 DIMM slots accommodate up to 128 GB of system memory (64 GB per slot) in a dual-channel configuration, with speeds ranging from 4400 MT/s up to 7600 MT/s via overclocking profiles. Both AMD EXPO and industry-standard XMP modules are supported, giving builders straightforward performance headroom through one-click profile activation. GIGABYTE’s X3D Turbo Mode BIOS feature applies tailored optimisation parameters that can improve gaming frame rates and reduce latency for compatible Ryzen 9000 Series processors, including non-X3D variants. The board also incorporates the company’s AI-Driven PCB technology — encompassing AI-ViaFusion, AI-Trace, and AI-Layer sub-technologies — which targets signal integrity through optimised via sizing, intelligent trace routing, and per-layer material selection. Thermal management centres on integrated molded heatsinks with a 5 W/mK thermal pad, a multi-cut fin design for improved airflow, and the Smart Fan 6 system. Smart Fan 6 supports PWM and DC fans plus water-cooling pumps, with up to 24 W (12 V × 2 A) per header, over-current protection, 7-point fan curves, and a Fan Stop function for silent operation under light loads. Connectivity is led by a Realtek RTL8851BE Wi-Fi 6 module covering 2.4 GHz and 5 GHz bands with 802.11ax (80 MHz) support and Bluetooth 5.3, complemented by a Realtek 2.5GbE wired LAN port. The rear I/O includes DisplayPort 1.4 (up to 3840×2160 @ 144 Hz) and HDMI 2.1 (up to 4096×2160 @ 60 Hz) for systems using integrated AMD Radeon graphics. Audio is delivered through a Realtek HD Audio CODEC supporting up to 7.1 channels, with a PCB-level noise guard separating analogue audio circuitry from digital interference. Storage options include one CPU-connected M.2 (PCIe 4.0 x4, types 2280/25) and one chipset M.2 (PCIe 3.0 x2, type 2280), alongside four SATA 6 Gb/s ports with RAID 0/1/10 support for SATA devices and RAID 0/1/5/10 for NVMe (RAID 5 restricted to Ryzen 9000 Series). USB provision spans back-panel USB 3.2 Gen 1 and USB 2.0 ports, plus internal headers including a USB Type-C header with USB 3.2 Gen 1 support.
