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.
Smart Fan 6 BIOS UI
1. Improve fan curve UI: We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.
2. 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.
3. Manual Input: For advanced users, we provide fan speed manual input for more precise control.
4. EZ Tuning: Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.
5. 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.
HDMI™ is a High-Definition Multimedia Interface which provides up to 5Gb/s video transmitting bandwidth and 8-channel high quality audio all through a single cable. Able to transmit superior, uncompressed digital video and audio, HDMI™ ensures the crispest rendering of digital content up to 1080p without the quality losses associated with analog interfaces and their digital-to-analog conversion. In addition, HDMI™ is compatible with HDCP (High-bandwidth Digital Content Protection), allowing the playback of Blu-ray/HD DVD and other protected media content.
4K resolution is the next technological milestone in high-definition content delivery, utilizing approximately 4,000 pixels on the horizontal axis, more than four times today's standard HD pixel density. GIGABYTE motherboards provide native 4K support with integrated AMD Radeon® Graphics via HDMI.
