Socket AM4 platform board

The MSI B450M MORTAR is a micro-ATX motherboard built on the AMD B450 chipset for Socket AM4 processors. It supports Ryzen 1st and 2nd Generation CPUs as well as Ryzen models with integrated Radeon Vega graphics. Four DDR4 slots run up to 3466 MT/s in dual-channel mode.

Builders needing legacy I/O or compact upgrades

This board suits builders who need a mix of modern and older ports: one PCIe 3.0 x16 slot, one PCIe 2.0 x16 slot, two PCIe x1 slots, four SATA 6Gb/s ports, two M.2 sockets, HDMI, DisplayPort, PS/2 and multiple USB 3.1 Gen 1 and Gen 2 Type-A connections. Users requiring integrated Wi-Fi or native PCIe 4.0 support should consider a different chipset.

Two M.2 sockets for fast storage

The board provides two M.2 connectors, allowing a pair of high-speed SSDs to be installed directly on the PCB. This is the key spec to verify when planning a compact system that relies on M.2 storage rather than 2.5-inch SATA drives.

Questions about this item

Will my existing AM4 cooler fit this board?

The board uses the standard AM4 socket so any cooler rated for AM4 will mount without extra brackets.

Can I run four sticks of DDR4 at the rated 3466 speed?

Four slots are wired for dual-channel DDR4; populating all four may require a lower frequency depending on the memory controller in your specific RYZEN processor.

Does the HDMI port work with a Ryzen CPU that has no integrated graphics?

The HDMI and DisplayPort outputs are driven by the processor; a RYZEN chip without Radeon Vega graphics will not provide video through those ports.
