Micro ATX AM4 motherboard

The GIGABYTE B450M DS3H V2 is a Micro ATX board built on the AMD B450 chipset for Socket AM4 processors. It accepts Ryzen 3rd Gen, 2nd Gen, 1st Gen and Athlon CPUs with Radeon Vega Graphics. Four 288-pin DDR4 slots support dual-channel memory up to 128 GB at speeds from 2133 to 3600 MHz (OC). The board provides HDMI and DVI-D outputs for integrated graphics.

Builders needing four DDR4 slots

This board suits builders who want four memory slots on a compact Micro ATX form factor and need HDMI or DVI-D for a display driven by the CPU graphics. It also provides an M.2 slot with PCIe Gen3 x4 and SATA modes for fast storage. Users who require more than four DIMM slots, additional video outputs beyond HDMI and DVI-D, or a different chipset feature set should consider other models.

Four DDR4 slots up to 128 GB

The key specification is the four 288-pin DDR4 slots supporting dual-channel memory up to 128 GB with speeds ranging from 2133 to 3600 MHz (OC). This capacity and slot count determine whether the board fits a memory-heavy build or a compact system that still needs maximum RAM headroom.

Questions about this item

What does the 3600 MHz DDR4 rating mean once the board is built?

3600 MHz is the highest overclocked memory speed the board can reach with compatible modules; standard speeds run at 2133, 2400, 2667, 2933 or 3200 MHz without overclocking

How does the PCIe Gen3 x4 M.2 slot limit drive performance?

The slot caps throughput at PCIe Gen3 x4 bandwidth, so NVMe drives faster than that will run at the slot's maximum instead of their rated peak

What physical space and mounting does the Micro ATX board need?

The board fits any Micro ATX or larger case with standard standoff holes and uses a 24-pin ATX plus 8-pin CPU power connector for installation
