GIGABYTE B840M D2H
GIGABYTE B840M D2H uses the AMD B840 chipset and an AM5 socket, supporting AMD Ryzen™ 9000, 8000, and 7000 series processors. Its mATX (Micro ATX) form factor ensures compact dimensions suitable for smaller builds, while the board offers a 5+2+2 phase digital power solution for stable processor power delivery. Thanks to X3D Turbo Mode, you can activate optimisation parameters with a single click. For Ryzen™ 9000 X3D processors, this boosts gaming performance, and for Ryzen™ 9000 non-X3D models, it achieves a similar level of performance to their X3D counterparts—up to 18% depending on the game. The board features two DDR5 slots with dual-channel support and AMD EXPO™ profiles, allowing memory overclocking up to 7600MT/s.

Expansion slots and storage
There are two PCIe slots available – one PCIe 4.0 ×16 with PCIe EZ-Latch for easy, one-click graphics card release, and one PCIe 3.0 ×4. For storage, the board offers two M.2 slots (one PCIe 4.0 ×4 and one PCIe 3.0) and four SATA III ports, providing flexible options for both fast NVMe drives and conventional storage.
Fast network connectivity and audio
The rear I/O panel includes a 2.5Gb LAN port for high-speed network connection with minimal latency, an HDMI 2.1 output, two USB 3.2 Gen 1 (USB 3.0) ports, four USB 2.0 ports, and an 8-channel sound card with high-end audio capacitors and Audio Noise Guard technology for a clean audio output.
Advanced features and user-friendliness
The board integrates UC BIOS with an intuitive interface, Q-Flash Auto Scan function for automatically finding the BIOS file on a USB drive, and an EZ Debug Zone with centralised LED indicators for quick diagnostics during PC assembly. The GIGABYTE Control Center software unifies control of RGB Fusion lighting, Smart Fan 6 for quiet and efficient cooling, and other tools. With technologies like D5 Bionic Corsa for AI overclocking and AI-Driven PCB Design for signal optimisation, the B840M D2H offers a modern platform focused on both performance and ease of use.

Choosing a motherboard
When choosing a motherboard (or mainboard), it is important to pay particular attention to the motherboard's socket type, format and chipset. These are among the most important parameters and ensure the board's compatibility with the processor, expansion cards and other components. The specific socket determines your choice of processor, while the remaining connectors dictate which other components you need for your future computer.Specifications
