GIGABYTE B550 Aorus Master

With similar sized product stacks to the other major motherboard vendors, GIGABYTE has more than ten B550 models ready for. Some of these cater to B550’s budget which is the chipsets core target market, but some do push the boat out in terms of features and quality. GIGABYTE’s premier B550 model is the B550 Aorus Master, and it has a very premium controller set for what is considered a ‘budget’ platform. Some of the B550 Aorus Master’s standout features include three PCIe 4.0 x4 M.2 slots, a Realtek 2.5 G Ethernet controller, an Intel Wi-Fi 6 interface, and support for up to DDR4-5200 memory.

The GIGABYTE B550 Aorus Master follows a similar design to previous iterations of its Master series with a black cut black and silver aesthetic, with integrated RGB LED lighting within the rear panel cover. The chipset heatsink includes the Aorus Falcon logo, while the boards power delivery heatsink looks large, which is designed to keep the boards 16-phase configuration cool during operation. The B550 Aorus Master uses fourteen Infineon TDA21472 70 A power stages for the CPU section, with two TDA21472 70 A power stages for the SoC, with an Infineon XDPE132G5C PWM controller.

The Master includes three full-length PCIe slots, with the top slot operating at PCIe 4.0 x16, and two full-length PCIe 3.0 x4 slots which is a very interesting design choice. There is also three PCIe 4.0 x4 M.2 slots which include their own individual M.2 heatsink, and six SATA ports with support for RAID 0, 1, and 10 arrays. The board has four memory slots which support up to DDR4-5200 which is higher than any X570 board prior to launch, with a maximum supported capacity of up to 128 GB.

On the rear panel is a single USB 3.2 G2 Type-C, five USB 3.2 G2 Type-A, and six USB 2.0 ports which is stacked for B series model. Included is a single Realtek RTL8125BG 2.5 G Ethernet controller, with and two antenna adaptors for the Intel AX200 Wi-Fi 6 interface which also supports BT 5.0 devices. The board includes a Q-Flash Plus button which allows users to flash the firmware at the click of a button, a single HDMI 2.1 video output, and 3.5 mm audio jacks and S/PDIF optical output powered by a Realtek ALC1220-VB HD audio codec.

Aside from the PCIe slot layout, looking at the GIGABYTE B550 Aorus Master on paper, it could easily be forgotten that this is a model on what is considered a budget-friendly chipset, or is supposed to be. The B550 Aorus Master is as premium as a motherboard comes with support for three PCIe 4.0 x4 M.2 drives, support for up to 128 GB of DDR4-5200, and a premium networking controller pairing that is seen only on mid-range X570 models. With all this comes a large price tag with an MSRP of $280, which is encroaching on mid-range X570 territory.

    Does anyone know if the boards that have the Intel i225-V are shipping with the fixed hardware (v2)? Reply

    Wow, another broken Intel NIC? I wish motherboards would stop using Intel NICs. Reply

    After Googling it looks like v2 is not fixed either... a v3 is coming out. Time to buy Realtek. Reply

    Which is hilarious - I remember when Realtek was the worst when it came to NICs, and Intel/3Com was the standard. :) Reply

    Yes, indeed...;) My x570 Master has an Intel gigabit & a realtek 2.5gb. It's amusing because my interface is an EWAN that tops out at 1Gb, but I thought I'd try the realtek just to see and then I forgot about it...;)...Seems every bit as stable as the Intel--still on it, lol...;) Six of one, half-dozen of another.

    Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks! Reply

    I'm just here for the Next mini-ITX boards. I'm liking the Aorus Pro AX quite a bit. Reply

    Most of these boards are a serious VRM upgrade over the B450 boards. If I was buying Ryzen right now I'd easily go B550 over X570.

    So, only the ASUS boards offer bios flashback? Seems like a cheaper, just as userful version of dual BIOS anyway.

    Finally ONE mini-ITX board with 3-monitor output. Reply
