Board for AM4 DDR4 builds

The MSI B450 Tomahawk Max is an ATX motherboard built for AMD AM4 processors and DDR4 memory. It supports memory speeds up to 4133 MHz when overclocked. An extended PWM heatsink covers the power delivery to keep high-end CPUs running at full speed. A rear Flash BIOS button lets you update firmware with only a USB key and no other components installed.

Suits single-GPU and CrossFire systems

Builders who want a single graphics card or a two-way AMD CrossFire setup will find reinforced STEEL ARMOR PCIe slots. The board does not meet the needs of buyers who require three or more graphics cards. It also lacks integrated Wi-Fi or Bluetooth, so users who need wireless connectivity must add a separate card. Overclockers who want more than four DIMM slots should look at larger platforms.

DDR4 support to 4133 MHz

The decisive specification is DDR4 memory support up to 4133 MHz when overclocked. This ceiling determines which memory kits can run at their rated XMP or DOCP profiles without manual tuning. If your chosen kit specifies a higher speed, the board will not reach that frequency. Match your memory to this limit to avoid stability issues or wasted performance headroom.
