MSI MAG B550M Vector Wifi DDR4 AMD Motherboard

The MSI MAG B550M Vector WiFi is a Micro-ATX motherboard built on the AMD B550 chipset, designed to support 3rd Generation AMD Ryzen Desktop Processors as well as AMD Ryzen 4000 G-Series Desktop Processors in the AM4 socket. Its compact 9.6 in. x 8.3 in. (24.4 cm x 21 cm) footprint makes it a practical choice for space-conscious builds without compromising on connectivity or feature set. Memory support spans two DDR4 UDIMM slots capable of holding up to 64 GB in a dual-channel configuration. JEDEC-rated speeds range from 1866 MHz up to 3200 MHz, while A-XMP overclocking mode extends potential speeds up to 4600+ MHz (1DPC 1R configuration). Both non-ECC and ECC UDIMM modules are supported, though ECC operates in non-ECC mode. Storage options include one M.2 Key-M slot routed directly from the AMD processor, supporting PCIe 4.0/3.0 x4 and SATA protocols in 2242, 2260, and 2280 form factors. The slot is covered by MSI's M.2 Shield Frozr thermal solution to manage SSD temperatures and reduce thermal throttling. Four SATA 6 Gb/s ports provide additional drive capacity, and the board supports RAID 0, 1, and 10 across SATA devices. Expansion is handled by one PCIe x16 slot (supporting PCIe 4.0 or 3.0 depending on the installed processor) alongside two PCIe 3.0 x1 slots. For displays, an HDMI 2.1 port and a DisplayPort output each support resolutions up to 4096×2160 at 60 Hz when using a Ryzen G-Series processor with integrated graphics. Wireless connectivity is provided by an Intel Dual Band Wireless-AC 3168 module, supporting Wi-Fi 802.11 a/b/g/n/ac on both 2.4 GHz and 5 GHz bands with speeds up to 433 Mbps. Bluetooth support covers versions 2.1 through 4.2 including BLE. Wired networking is handled by a Realtek RTL8111H Gigabit LAN controller. Audio is powered by a Realtek ALC892/ALC897 codec delivering 7.1-channel high-definition audio. RGB personalisation headers include one 4-pin RGB LED connector and one 3-pin addressable RAINBOW LED connector. The board also includes an extended PWM heatsink design and a 2 oz thickened copper PCB to improve thermal performance and signal integrity. A 3-year warranty is included.
