NVMe PCIe 4.0*/3.0 M.2 Connector

With NVMe PCIe 4.0*/3.0 x4 M.2 connector onboard, GIGABYTE Motherboards bring users to experience NVMe mode or SATA mode connectivity with delivering up to 64 Gb/s data transfer speed.

GbE LAN

Gigabit Ethernet (GbE) LAN provides significantly faster data transfer speeds of up to 1 Gbps, which is ten times faster than traditional 100 Mbps Fast Ethernet, enabling smoother streaming, faster file transfers, and more responsive network applications.

Smart Fan 6

Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. Multiple fan headers can support PWM/DC fan and pump, and users can easily define each fan curve based on different temperature sensors across the board via intuitive user interface.

• High Current Support: Each fan headers support PWM and DC fan and Water Cooling Pump , and up to 24W (12V x 2A) with Over-Current Protection

• Precision Control: Multiple temperature/fan speed control points for precise fan curve

• Dual Curve Mode: Slope/Stair dual mode for different user scenario

• Fan Stop: Fan can stop completely below users’ specified temperature point

Smart Fan 6 BIOS UI

• Improve fan curve UI: We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.

• Slope/Stair dual graph mode: Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval.

• Manual Input: For advanced users, we provide fan speed manual input for more precise control.

• EZ Tuning: Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.

• Fan curve profile: Fan curve profile can be saved in BIOS ROM, profile will be kept after updating BIOS.

High-End Audio Capacitors

GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help 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.
