Gigabyte B840M DS3H is one of the first motherboards based on the AMD B840 chipset, which replaces the A620. The main advantage is factory support for all three generations of Ryzen processors for the AM5 socket: series 7000, 8000, and 9000. There is no longer a need to flash the BIOS with a USB flash drive to start the system. The power subsystem is organized in an 8+2+2 phase scheme—for the processor, integrated graphics, and SoC.
Pull the Ear
The heatsink cools the lower VRM shoulder and one of the two M.2 slots, which is equipped with a Thermal Guard heat-dissipating plate. Both slots support screwless mounting of drives, and the graphics card slot is complemented by a convenient EZ-Latch fastener—it allows easy removal of the GPU even in tight spaces. The rear panel includes three digital video outputs from the iGPU, and a front internal USB Type-C can be connected.
Overclocking via AI
The board supports two intelligent overclocking functions: X3D Turbo Mode and Aorus AI Snatch. In the first case, an additional CCX chiplet is deactivated to primarily engage the one where there is a 3D cache, which is useful in games. In the second, artificial intelligence determines the optimal frequencies for the CPU and DDR5 RAM (up to 8200 MT/s, but now in asynchronous mode). A 2.5 Gbps Ethernet adapter and a 7.1-channel audio chip from Realtek handle the network and sound.
