PERFORMANCE
10+3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs
GIGABYTE UD series motherboards use a 10+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.
1. PCIe 4.0 Slot
PCIe 4.0 x16 slot with faster bandwidth and lower impedance.
2. M.2 PCIe 4.0 Slot
M.2 PCIe 4.0 x4 slot with Lower impedance.
* Product uses PCIe 4.0 grade material, actual support varies by hardware configuration.
CONNECTIVITY
Dual Band 802.11ac Wi-Fi
The onboard 802.11ac Wi-Fi module from Intel® supports Dual Band and up to 1.73Gbps, 5x faster Wi-Fi speed than 802.11n and also support BLUETOOTH 5.
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.
Dual NVMe PCIe 4.0*/3.0 M.2 Connectors
With NVMe PCIe 4.0*/3.0 x4 and PCIe 3.0 x4 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.



USB Type-C™ Front Panel Connector
Equipped with next generation connectivity, GIGABYTE Motherboards already support the chassis of the future. The onboard USB Type-C™ header for USB 3.2 Gen1 makes access convenient when connecting a USB 3.2 Gen1 device or charging your mobile device.
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 – 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.
Note: Only New Gen AMD Ryzen™ with Radeon™ Graphics processors support displaying function.

ULTRA DURABLE

GIGABYTE Patented Double Locking Bracket
Solid Pin Power Connectors
GIGABYTE motherboards feature solid plated ATX 12V 8pin power connectors to offer a stable power supply during CPU overloading.
Solid Pin Power connector advantages
  1. Larger contact area for electricity
  2. More metal quantity to sustain higher power and generated heat
  3. 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 whole new meaning.
