MSI B450M Bazooka Max Wifi DDR4 AMD Motherboard

The MSI B450M Bazooka Max WiFi is a Micro-ATX motherboard built on the AMD B450 chipset, designed for Socket AM4 processors including 1st, 2nd, and 3rd Generation AMD Ryzen desktop CPUs, as well as Ryzen processors with Radeon Vega Graphics and Athlon with Radeon Vega Graphics desktop processors. For memory, the board provides four DDR4 DIMM slots supporting dual-channel configuration with a maximum capacity of 128GB (requires ComboPI 1.0.0.3-based BIOS or above). Base JEDEC speeds range from 1866 MHz to 2667 MHz, while A-XMP overclocking profiles push supported memory up to 4133 MHz on Ryzen Gen 3 (R5/R7/R9) platforms. Both non-ECC UDIMM and ECC UDIMM (operating in non-ECC mode) modules are supported. Storage options include four SATA 6Gb/s ports alongside one M.2 Key-M slot compatible with 2242, 2260, and 2280 form-factor drives, running at PCIe 3.0 x4 with Ryzen processors or PCIe 3.0 x2 with Athlon processors. The B450 chipset also enables RAID 0, RAID 1, and RAID 10 configurations across SATA devices. For expansion, the board features one PCIe 3.0 x16 slot (full x16 speed with Ryzen 1st–3rd Gen) reinforced with MSI’s Steel Armor, and one PCIe 2.0 x16 slot operating at x4 mode, enabling 2-Way AMD CrossFire multi-GPU configurations. Connectivity is handled by an Intel Wireless-AC 3168 module delivering Wi-Fi 802.11 a/b/g/n/ac on single band (2.4 GHz or 5 GHz) at up to 433 Mbps, paired with Bluetooth 4.2 support. Wired networking is provided by a Realtek 8111H Gigabit LAN controller. Audio is managed by a Realtek ALC892 codec delivering 7.1-channel High Definition Audio with isolated audio circuitry for reduced interference. USB connectivity combines chipset-driven USB 3.2 Gen 1 (2 internal, via header) and USB 2.0 (4 rear panel + 4 internal via headers) with four processor-driven USB 3.2 Gen 1 Type-A ports on the rear panel. The rear I/O also includes an HDMI output, PS/2 combo port, and HD audio jacks. The board ships in the standard mATX form factor at 9.6 in. x 9.6 in. (24.3 cm x 24.3 cm) with 8 mounting holes, a 128 Mb UEFI AMI BIOS with ACPI 6.2 and SMBIOS 3.2 support, EZ Debug LED indicators for fast troubleshooting, and headers for 2 RGB and 2 ARGB LED strips. MSI backs this product with a 3-year warranty. Verified Specifications: – Chipset: AMD B450 – Socket: AM4 – Form Factor: mATX, 9.6 in. x 9.6 in.
