Gigabyte B840M D2H mATX Motherboard | AM5 | 2x DDR5 Slots
Description
The Gigabyte B840M D2H is a compact mATX motherboard built around AMD's B840 chipset for AM5 processors. This budget-friendly option supports the latest AMD Ryzen 7000, 8000, and 9000 series CPUs, making it ideal for mainstream builds where space is limited but performance matters. The board's 5+2+2 phase VRM design provides stable power delivery for modern processors without the premium cost of higher-tier chipsets.
Memory capabilities include dual DDR5 slots supporting up to 128GB with speeds reaching 7600MHz, giving you room for future upgrades. Storage options include two M.2 slots - one PCIe 4.0 slot supporting drives up to 25110mm (M.2 2580) for maximum performance, plus a second PCIe 3.0 slot for 2280 drives. The single PCIe x16 slot handles discrete graphics cards, while 2.5 Gigabit Ethernet and USB 3.2 Gen 1 ports provide solid connectivity for everyday computing tasks.
Setup is straightforward with AMD EXPO memory profile support for easy DDR5 overclocking. The board includes practical RGB headers for lighting customization and dedicated connectors for CPU fans and water pump systems. In the box you'll find the motherboard with pre-installed I/O shield, mounting screws, and a CR2032 CMOS battery. The three-year warranty covers your investment in this no-nonsense foundation for compact AMD builds.
