Gigabyte B840M H AM5 DDR5 Micro ATX Motherboard

The Gigabyte B840M H is a Micro ATX board for the AMD AM5 platform, offering a modern base with DDR5 memory and X3D Turbo Mode support to unleash gaming performance. It targets builders assembling a current Ryzen system with a compact profile and tidy connectivity.

Platform & chipset

The board is based on the AMD B840 chipset in the AM5 socket and supports AMD Ryzen 9000, 8000 and 7000 series processors. X3D Turbo Mode is designed to unlock a new level of gaming performance, and a friendly BIOS with multi-theme support, AIO Fan Control and Q-Flash Auto Scan keeps setup and maintenance straightforward.

Memory & expansion

Two DIMM slots in a dual-channel arrangement support DDR5 memory with AMD EXPO module support for quick memory-profile tuning. For expansion there is a PCIe x16 slot with an EZ-Latch mechanism for quick, convenient release of the graphics card, which simplifies building and upgrading.

Power, cooling & connectivity

Power delivery is built as a 5+2+2 phase digital design for steady feeding of the processor. Fast storage is served by an M.2 slot on a PCIe 4.0 x4 interface, and networking is based on a GbE LAN connection. This combination gives the SSD a wide data path alongside a reliable wired network link for everyday use.
