Realtek 8118 Gaming Exclusive LAN
High-speed Gigabit LAN with automatic bandwidth allocation
Realtek 8118 LAN is a high-performance and friendly network chip for game players with automatic bandwidth allocation to ensure top network priority of the game or application. It can provide users with the most complete functions and the fastest and smoothest Internet experience.

HDMI 2.1 for 4K/60P/21:9/HDCP 2.3 Support
HDMI 2.1, which is backward compatible with HDMI 2.0/1.4 and offers 48 Gb/s of bandwidth, twice as much as the previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native 21:9 cinematic ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to deliver the best viewing experience for the spectators.

Smart Fan 5
With Smart Fan 5, users can ensure that their gaming PC can maintain stable performance while staying cool. Smart Fan 5 allows users to swap their fan connectors to reflect different thermal sensors in different locations on the motherboard. Additionally, with Smart Fan 5, the hybrid fan connectors support PWM and voltage fans, this makes the motherboard more adapted to mounting liquid cooling.

Achieve silence of the fans.
With Fan Stop, map any fan to stop completely when temperatures drop below a specific threshold. Which fan stops, based on what sensor readings and at what temperature, everything can be customized to your liking.

RGB Fusion 2.0
With B550 motherboards, RGB Fusion 2.0 is even better with addressable LEDs. RGB Fusion 2.0 gives users the option to control onboard RGB and external RGB/addressable LED light strips* for their PC build. Already feature packed with colors and patterns, RGB Fusion 2.0 is now updated to improve support for addressable LEDs. Featuring external addressable LED strips, where each LED is digitally addressable so users can experience even more patterns, styles and illuminations.

With B550 motherboards, external 5V addressable LED lighting strips and up to 300 LED lights are supported. RGB Fusion 2.0 with addressable LEDs comes with new patterns and various speed settings with more to come.

RGB Fusion 2.0
With a built-in intuitive user interface, RGB Fusion 2.0 offers you a better solution to customize lighting effects on all supported devices. From motherboards, graphics cards to peripheral products, you can customize your gaming rig in your own style and show off your build by sharing the profiles. Additionally, the new game mode makes lighting effects interactive with select games to give you the most immersive gaming experience.

High-end audio capacitors
GIGABYTE motherboards use high-end audio capacitors. These high-quality capacitors help deliver high-resolution, high-fidelity audio to provide the most realistic sound effects for gamers.
Protection against noise
GIGABYTE motherboards feature an audio noise shield that essentially separates the board's sensitive analog audio components from potential noise contamination at the PCB level.

Q-Flash Plus
Update BIOS easily without installing CPU, memory and graphics card.

With GIGABYTE Q-Flash Plus, you don't need to install the CPU, memory and graphics card or enter the BIOS menu to update the BIOS. Simply download and save a new BIOS file (rename gigabyte.bin) to the USB flash drive, then press the dedicated Q-Flash Plus button and you're done.
