GIGABYTE B550 Aorus Master Wifi AM4 DDR4 AMD Motherboard

The GIGABYTE B550 Aorus Master WiFi is a full-size ATX motherboard built on the AMD B550 chipset, designed for AMD Socket AM4 and compatible with 3rd Generation AMD Ryzen processors as well as the New Generation AMD Ryzen with Radeon Graphics processors. Measuring 30.5 cm x 24.4 cm, it fits standard ATX enclosures and provides a robust foundation for high-performance desktop builds. Power delivery is handled by a direct 16-phase digital VRM solution using 70A power stages, paired with an advanced thermal design that includes a Fins-Array heatsink, direct-touch heatpipe, and a thermal baseplate — helping sustain stable power under extended workloads. Dual 8-pin and 4-pin ATX 12V connectors supplement the standard 24-pin main connector. Memory support covers four DDR4 DIMM slots with a maximum capacity of 128 GB (up to 32 GB per DIMM). With 3rd Gen Ryzen processors, the board supports DDR4 speeds from 2133 MHz up to 5200 MHz (O.C.), with XMP profiles also supported. ECC unbuffered DIMMs in 1Rx8/2Rx8 configuration are accepted alongside standard non-ECC modules. Storage options are extensive: three M.2 Socket 3 connectors (M key, supporting 2242/2280/22110 SSDs), with the primary CPU-connected M.2 slot (M2A_CPU) supporting both SATA and PCIe 4.0 x4 SSDs on 3rd Gen Ryzen. The remaining two CPU-connected M.2 slots (M2B_CPU/M2C_CPU) support PCIe 4.0 x4 SSDs, all three equipped with thermal guards. Additionally, six SATA 6 Gb/s ports (with RAID 0, 1, and 10 support) round out storage connectivity. Wireless connectivity is provided by an Intel Wi-Fi 6 AX200 module supporting 802.11a/b/g/n/ac/ax on 2.4 GHz and 5 GHz dual-band frequencies with 2T2R antennas, reaching up to 2.4 Gbps data rates and 160 MHz channel width. Bluetooth 5 is also integrated. Wired networking uses a Realtek 2.5GbE LAN chip supporting 2.5 Gbit, 1 Gbit, and 100 Mbit speeds. Audio is powered by the Realtek ALC1220-VB codec with WIMA capacitors delivering 120 dB SNR on the rear output, DTS:X Ultra support, 7.1-channel audio, and S/PDIF optical output. The back panel offers 5 x USB 3.2 Gen 2 Type-A ports, 1 x USB 3.2 Gen 2 Type-C port, 6 x USB 2.0/1.1 ports, 1 x HDMI port (supporting up to 4096×2160 @ 60 Hz via HDMI 2.1 when using APU), and 5 audio jacks. RGB FUSION 2.0 supports addressable LED strips and RGB LED strips via dedicated headers. Smart Fan 5 provides noise detection, hybrid fan headers with fan-stop capability, and multiple temperature sensor inputs. BIOS reliability is ensured by Gigabyte’s DualBIOS with AMI UEFI firmware, while Q-Flash Plus enables BIOS updates without installing a CPU, memory, or GPU.
