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

PERFORMANCE

5+3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs

GIGABYTE AORUS 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.

Benefits of Low RDS(on) MOSFETs

  • Optimized gate charge to minimize switching losses.
  • Lower temperature, smaller size, better thermal characteristics.

WiFi 6E 802.11ax + BT 5.3 Module

Wireless solution 802.11ax WIFI 6E with new dedicated 6GHz band, enables gigabit wireless performance and provides smooth video streaming, better gaming experience. Moreover, Bluetooth 5.3 provides 4X range over BT 4.2 and with faster transmission.

Benefit of WiFi 6E

  • Dedicated spectrum in 6GHz band for less interference
  • 4X better network capacity, no traffic jams especially in those dense area with lots of devices
  • Network efficiency increase for better user experience

Dual NVMe PCIe 4.0*/3.0 M.2 Connectors

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.

Realtek GbE LAN with Bandwidth Management

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.
