Product features

AMD StoreMI technology
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. The benefits of AMD StoreMI: making the PC experience fast, smooth and easy; optimizing computer responsiveness from system boot to application launch; offering SSD performance with HDD capacity at an affordable cost; quickly accessing key files by automatically learning users' computing behaviors.
5+3 phases pure digital VRM solution with low RDS(on) MOSFETs
GIGABYTE UD series motherboards use a 5+3 phases pure digital PWM + low RDS(on) MOSFETs design to support advanced 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. Benefits of low RDS(on) MOSFETs: optimized gate charge to minimize switching losses; lower temperature, smaller size, better thermal characteristics.
Faster and better coverage with Intel dual-band 802.11ac Wi-Fi + BT 4.2 module
The onboard 802.11ac Wi-Fi module from Intel supports dual-band Wi-Fi and Bluetooth 4.2.
High-speed Gigabit LAN with automatic bandwidth allocation
Realtek 8118 LAN is a high-performance and friendly network chip for gaming players with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can provide users the most comprehensive features and the fastest and smoothest Internet experience.
HDMI 2.1 for 4K/60P/21:9/HDCP 2.3 support
HDMI 2.1, which is backwards compatible with HDMI 2.0/1.4 and offering 48 Gb/s of bandwidth. This lets users transfer multiple video streams, as well as a native cinematic 21:9 ratio, Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers.
LAN static-electricity and surge protection
GIGABYTE motherboards use ICs with great resistance levels. This helps to better protect the motherboard and its components against potential damage caused by static electricity. GIGABYTE motherboards also feature special anti-surge ICs that protect your motherboard and your PC from any surge in power delivery that may occur, helping to ensure that your PC is equipped to deal with any potentially irregular and inconsistent power delivery.
Smart Fan 5
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.
Fan Stop
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.
Hybrid fan pin headers
Assume complete control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow rate and water temperature through the hybrid fan pin headers or external thermistor sensors - giving you absolute mastery over your PC. All hybrid fan headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode.
Quality audio capacitors
GIGABYTE motherboards use quality audio capacitors. These high-quality capacitors help to deliver high-resolution and high-fidelity audio to provide the most realistic sound effects for gamers.
Audio noise guard
GIGABYTE motherboards feature an audio noise guard that essentially separates the board's sensitive analog audio components from potential noise pollution at the PCB level.
Q-Flash Plus
Update the BIOS easily without installing the CPU, memory and graphics card. With GIGABYTE Q-Flash Plus, you don't need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS.
Solid pin power connectors
B550 motherboards feature solid plated ATX 12V 8-pin power connectors for offering stable power supply while CPU overloading. Solid pin power connector advantages: larger contact area for electricity; more metal quantity to sustain higher power and generated heat; ultra durable and longer lifespan.
Start sulfurization protection
Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an anti-sulfur design GIGABYTE gives ultra durable motherboards a different meaning.
