Support for DDR4 XMP up to 5300MHz

AORUS offers a tested and proven platform that ensures proper compatibility with profiles up to 5300MHz and beyond. All users need to do to achieve this performance boost is to ensure that their memory module is capable of XMP and that the XMP function is enabled and activated on the AORUS motherboard.

PCIe 4.0 Design

Two M.2 PCIe 4.0/3.0 Slots

The B550 AORUS motherboards offer the best industry compatibility in terms of NVMe storage for users who require high capacity and seek the best performance. The unique AORUS design can be configured in RAID for record speeds of up to 6560 MB/s (sequential read), making AORUS the obvious choice for the ultimate computer.

Cooling

Smart Fan 5

With Smart Fan 5, users can ensure that their gaming computer can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. And not only that, with Smart Fan 5, more hybrid fan headers that support both PWM fans and Voltage mode fans have been introduced, making the motherboard more liquid cooling friendly.

Fan Stop

With Fan Stop, each fan will completely stop when temperatures drop below a specified limit. Which fan stops, based on readings from which sensor and at what temperature, all of these can be customized to your preferences.

Hybrid Fan Pin Headers

Gain complete control over your water cooling setup. Smart Fan 5 receives updated information about the flow rate through the Hybrid Fan Pin Headers, giving you absolute oversight of your computer. All Hybrid Fan Headers can automatically detect the type of cooling device, whether it is a fan or a pump with different PWM or Voltage operation.

2.5G LAN

The adoption of LAN 2.5G provides network connectivity of up to 2.5 GbE, with at least twice the transfer speeds compared to general 1GbE networking. It is ideal for gamers and streamers for an absolute and smooth online experience. Additionally, it is compatible with Multi-Gig (10/100/1000/2500Mbps) RJ-45 ethernet.

WIFI 6 802.11ax

Intel's wireless solution supports 802.11ax, allows gigabit wireless performance, provides smooth video streaming, better gaming experience, fewer dropped connections, and speeds up to 2.4 Gbps. Additionally, Bluetooth 5 offers 4X the range compared to BT 4.2 and faster transmission.

    Very high-quality motherboard, it requires a little attention to the coolers it can support, and it is worth noting that its socket is slightly shifted compared to other chipsets of the same kind. The Noctua NH-L12S fits perfectly, even though the Noctua website does not mention it, and there is no need to remove the I/O cooler. However, Gigabyte provides incorrect drivers for Bluetooth and Wi-Fi on their website. Find the corresponding drivers from the chip's website that the version you purchased uses, as it may have different chips depending on the revision.

    The motherboard is very good, it seems to be of high quality and offers various things like cooling for the front m.2. Easy to install, everything worked immediately and all 11 played without any complaints. You can see the ports and decide if it's enough, but they covered me. Unfortunately, it loses in software, which, like all devices of this particular company, is tragic, ugly, and difficult to use. It does its job, but leaves a feeling of cheapness and lack of attention.

    I have built 2 PCs with this motherboard. Overall, I didn't have any issues. The only thing that worried me was when at some point, in the second one which is also rev 1.1, the Bluetooth disappeared and after a lot of searching, I managed to find other drivers to make it work again. Also, the RGB management software is completely terrible and doesn't work. Other than that, it's okay!

    Finally, I was forced to install a fan only for the chipset. The reason I bought it was that it doesn't have a fan, but after experiencing daily BSODs, which were caused solely by the motherboard overheating, I will go through the RMA process.

    It works practically flawlessly for months. At some point, it had a minor issue with sporadic ethernet disconnections, which were "fixed" by disconnecting and reconnecting the cable. This seems to have been resolved for quite some time now through a driver update.

    However, it is NECESSARY to perform a BIOS update after installation. There were various issues with these motherboards in the past, but they have been resolved with the latest Gigabyte BIOS updates.

    From the first week, the RGB output got stuck and the lights on the motherboard don't turn on either, and as new, it didn't post on a 4K screen, so I had to connect it to a regular monitor to install Windows

    Very high-quality motherboard, it requires a little attention to the coolers it can support, and it is worth noting that its socket is slightly shifted compared to other chipsets of the same kind. The Noctua NH-L12S fits perfectly, even though the Noctua website does not mention it, and there is no need to remove the I/O cooler. However, Gigabyte provides incorrect drivers for Bluetooth and Wi-Fi on their website. Find the corresponding drivers from the chip's website that the version you purchased uses, as it may have different chips depending on the revision.

    The motherboard is very good, it seems to be of high quality and offers various things like cooling for the front m.2. Easy to install, everything worked immediately and all 11 played without any complaints. You can see the ports and decide if it's enough, but they covered me. Unfortunately, it loses in software, which, like all devices of this particular company, is tragic, ugly, and difficult to use. It does its job, but leaves a feeling of cheapness and lack of attention.

    I have built 2 PCs with this motherboard. Overall, I didn't have any issues. The only thing that worried me was when at some point, in the second one which is also rev 1.1, the Bluetooth disappeared and after a lot of searching, I managed to find other drivers to make it work again. Also, the RGB management software is completely terrible and doesn't work. Other than that, it's okay!

    Finally, I was forced to install a fan only for the chipset. The reason I bought it was that it doesn't have a fan, but after experiencing daily BSODs, which were caused solely by the motherboard overheating, I will go through the RMA process.

    It works practically flawlessly for months. At some point, it had a minor issue with sporadic ethernet disconnections, which were "fixed" by disconnecting and reconnecting the cable. This seems to have been resolved for quite some time now through a driver update.

    However, it is NECESSARY to perform a BIOS update after installation. There were various issues with these motherboards in the past, but they have been resolved with the latest Gigabyte BIOS updates.
