Socket AM4 Micro-ATX Foundation

The MSI MAG B550M Bazooka is a Micro-ATX motherboard built on the AMD B550 chipset for Socket AM4 processors. It supports 3rd Gen AMD Ryzen CPUs and future Ryzen processors with a BIOS update. The board provides a compact platform for mainstream desktop builds.

Value Builders And Compact Cases

This board suits builders who need a small form factor with dual-channel DDR4 support up to 128 GB across four slots. It offers one PCIe x16 slot, two PCIe x1 slots, four SATA III ports and two M.2 interfaces. Users needing more than one full-size graphics slot or extensive rear I/O should look at full-size ATX alternatives.

Dual-Channel DDR4 Up To 4400 MHz

Memory compatibility is the decisive specification. The board validates dual-channel DDR4 speeds from 1866 through 4400 MHz. Matching your kit to this supported range determines whether the system will post and run at the intended frequency.

Questions about this item

Will my existing DDR4 memory modules work at 3200 MHz on the MAG B550M Bazooka?

The board supports dual-channel DDR4 at 3200 MHz among many other speeds up to 4400+ MHz so your modules will run at that frequency if they are rated for it.

How can I confirm the Realtek ALC892/897 audio codec is functioning after I build the system?

Install the Realtek audio driver from MSI's support page then open the sound control panel and verify 7.1-channel output is selectable and plays test tones on each channel.

Which accessories are included and what must I source separately for a complete build?

The box contains the motherboard a CMOS battery one SATA cable and the rear I/O shield; you will need to supply a CPU cooler mounting hardware RAM modules storage drives and a power supply.
