Gigabyte B840M DS3H mATX Motherboard | AM5 | 4x DDR5 Slots
Description
The Gigabyte B840M DS3H is an mATX motherboard built around AMD's B840 chipset, designed to support the latest AMD Ryzen 7000, 8000, and 9000 series processors through the AM5 socket. This budget-friendly board strikes a practical balance between essential features and affordability, making it well-suited for mainstream builds where space is at a premium but performance expectations remain solid. The 8+2+2 phase VRM design provides stable power delivery for these modern processors without unnecessary complexity.
Memory support is comprehensive with four DDR5 slots accommodating up to 256GB of system RAM, with speeds reaching as high as 8200MHz when paired with compatible modules and proper XMP configuration. Storage connectivity includes two M.2 slots, both supporting PCIe 4.0 for fast NVMe drives, while a single PCIe 4.0 x16 slot handles discrete graphics cards. Network connectivity comes via 2.5 Gigabit Ethernet, offering faster wired speeds than standard gigabit connections, alongside USB 3.2 Gen 1 ports for peripherals.
The board includes practical touches like RGB LED pin headers for lighting customization, dual CPU fan connectors, and water pump connectors for custom cooling setups. Essential accessories ship in the box including mounting screws, while the CR2032 CMOS battery comes pre-installed. With its three-year warranty and focus on core functionality over premium extras, this motherboard delivers the fundamentals needed for a reliable AM5 system build.
