GIGABYTE B550 motherboards maximize your PC's potential with AMD StoreMI technology. StoreMI accelerates traditional storage devices to reduce boot times and enhance the overall user experience. This easy-to-use utility combines the speed of SSDs with the high capacity of HDDs into a single drive, enhances the read/write speeds of the device to match that of SSDs, bolsters data performance for incredible value, and transforms the everyday PC to a performance driven system.

With B550 Motherboards, RGB Fusion 2.0 is even better with Addressable LEDs. RGB Fusion 2.0 offers users the option to control onboard RGB and external RGB / Addressable LED light strips* for their PC build. Already feature filled with colors and patterns, RGB Fusion 2.0 are now upgraded to improve the Addressable LED support. With external Addressable LED strips, where each LED is digitally addressable that users can experience even more patterns, styles, and illuminations. With B550 Motherboards support the external 5V Addressable LED lighting strips and up to 300 LED lights. RGB Fusion 2.0 with Addressable LEDs comes with new patterns and various speed settings with more to come. * The external RGB LED strips and Addressable LED strips are not included with Motherboard purchase.

GIGABYTE UD series motherboards use a 5+3 phases pure digital PWM + Low RDS(on) MOSFETs design to support the 3rd Gen AMD Ryzen™ CPUs by offering incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability.

The onboard 802.11ac WIFI module from Intel® supports Dual Band and up to 433 Mbps, 3x faster WIFI speed than 802.11n and also support BLUETOOTH 4.2.

With NVMe PCIe 4.0*/3.0 x4 and PCIe 3.0 x2 M.2 connectors onboard, GIGABYTE Motherboards bring users to experience NVMe mode or SATA mode connectivity for M.2 SSD devices. Delivering up to 64 Gb/s data transfer speed, the dual M.2 connectors design provides an ideal storage solution while also supporting in RAID modes. *Actual support may vary by CPU.

Realtek Gigabit LAN features a network bandwidth management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.

HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth – twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers.

With Smart Fan 5 users can ensure that their gaming PC 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. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.

Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—all of it can be customized to your liking.
