Connectivity
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.
- PCIe 4.0 x4 M.2 - Up to 64 Gb/s* (NVMe)
- PCIe 3.0 x4 M.2 - Up to 32 Gb/s* (NVMe)
*Theoretical Bandwidth
*Actual support may vary by CPIL
PCIe 4.0* Hardware Design
* Product uses PCIe 4.0 grade material, actual support varies by hardware configuration.
Slot Signal Stability*
- PCIe 4.0 Slot - 3.3x Higher
- PCIe 3.0 Slot - Differential Impedance
*Based on PCIe 4.0 differential impedance specification
PCIe Bandwidth*
- PCIe 4.0 x16 (Up to 31.5GB/s*) - 2x Bandwidth
- PCIe 3.0 x16 (Up to 15.8GB/s*) - Transfer speed
*Theoretical bandwidth based on PCI Express specification
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.
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.
Cooling
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.
- Fan Connectors
- Internal Temperature Sensors
Different models have different number of fan pin headers and temperature sensors. Smart Fan 6 function may vary by model.
- 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: Increased 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, fan speed manual input control is provided.
- 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.
Audio
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 analogue audio components from potential noise pollution at the PCB level.
Ultra Durable
GIGABYTE Patented Double Locking Bracket

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.
4K Ultra HD Support
4K resolution is the next technological milestone in high-definition content delivery, utilising 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.
*4K display support is dependent on CPU
HDMI™ - The Next Generation Multimedia Interface
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 analogue interfaces and their digital-to-analogue 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.
Backed by a 3 year Gigabyte warranty.
