RGB FUSION

Set the Color that Matches Your Style

GIGABYTE's X299 series motherboards boast the most advanced LED system in the market today. With more customizability than ever and a convenient and intuitive UI thanks to the RGB Fusion App, you’ll have a blast making your GIGABYTE your own. For a more functional use, the bright and vibrant LEDs can be configured to display the PC’s temperature or load. For even more LED goodness RGBW strips are now supported for more true and vibrant whites.

RGB Fusion with Digital LEDs

With GIGABYTE X299 Motherboards, RGB Fusion is even better with Digital LEDs.* RGB Fusion offers users the option to control external LED light strips for their PC. Already feature filled with colors and patterns, RGB Fusion on X299 Series GIGABYTE Motherboards are now upgraded with Digital LED support. With external digital LED strips*, where each LED is digitally addressable, users can experience even more patterns, styles, and illuminations.
GIGABYTE Motherboards will support either 5v or 12v digital LED strips. RGB Fusion with Digital LEDs comes with 9 new patterns and various speed settings with more to come.

RGB Fusion (Advanced mode)

With the all new RGB Fusion software, users have access to different preset LED lighting configurations with choice of colors. You can even set the LEDs to synchronize with your favorite music or have them change colors to indicate the CPU temperature. For true lighting experts there is an Advanced Mode, which can be fully customized by individual area with its own effects and color transitions, along with specific duration and transition times.

GIGABYTE RGB Fusion APP

Don't just make your PC shine, make it a work of art that friends will envy. With the GIGABYTE RGB Fusion mobile app users can watch as they control the lighting within their gaming PC. This gives users ease of access as they try and adjust colors and speeds for different modes, all this can be achieved away from the keyboard and monitor of their PC.

Supports RGBW & - UV Light Strips

Independently Programmable Onboard Pin Header for RGBW/-UV LED Strips

Not bright enough? You can install standard 12V external RGB, RGBW or RGB/UV light strips on the RGBW pin header and control its color from the RGB Fusion software. Using a RGBW light strip with a dedicated white LED, users will experience brighter and more vibrant shades of colors.
When using RGB/UV LED strips, users can give their systems a fluorescent glow with the use of UV reactive liquid, neon braided cables, and acrylic paint for a wicked-looking gaming PC.
No need to worry when choosing light strips as GIGABYTE motherboards support a wide variety of RGBW/-UV light strips on the market thanks to the RGB Fusion software that allows users to redefine the pin location for the R/G/B Signal.

ALC 1220 120dB SNR HD Audio with Smart Headphone Amp

ALC 1220 120dB SNR HD Audio
The ALC1220 is a high-performance multi-channel High Definition Audio Codec with up to 120dB SNR for crystal clear audio and features such as Smart Headphone Amp, 114dB SNR recording for precise voice chats and hardware decoding of DSD128, ensuring users get the best possible audio quality from their PC.

Smart Headphone AMP

Automatically detects impedance of your head-worn audio device, whether earbuds or high-end headphones to provide optimal audio dynamics—preventing issues such as low volume and distortion.

Smart Fan 5

With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.

Achieve fan silence.

With Fan Stop map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—all of it can be customized to your liking.

Hybrid Fan Pin Headers & Temperature Sensors

Assume complete control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow-rate and water-temperature through the Hybrid Fan Pin Headers or external thermistor sensors—giving you absolute mastery over your PC.
• All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode.
• Includes support for one High-Current Pump up to 3 Amps with built-in overcurrent protection—a must for high-end high current fans.

New Smart Fan 5 Software

Choose from different modes, Quiet to Full Speed, to match your system usage scenario.
For each fan or pump, you can use the intuitive fan curve to define trigger thresholds and corresponding fan speeds.

System Information Viewer

GIGABYTE System Information Viewer is a central location that gives you access to your current system status. Monitor components such as the clocks and processor, set your preferred fan speed profile, create alerts when temperatures get too high or record your system’s behavior; these are the possibilities of the System Information Viewer.

Turbo B-Clock

Built-in Advanced Performance Tuning IC
Turbo B-Clock Tuning IC in the X299 series motherboards enable overclockers to have the ability to change their BCLK frequency to a desired value of their choice. With the new linear range adjustment option of the Tuning IC, ranges from 90MHz to 500MHz are now possible, so that overclockers are not limited to the 5% ranges of traditional straps.
CPU PEG bus, chipset PCIe bus and DMI bus (link between CPU and chipset) have the ability to change from default of 100MHz linearly up to 200MHz synchronously 
*Turbo B-Clock overclocking range may vary according to CPU, chipset and used devices capabilities.

Dual Ultra-Fast NVMe PCIe Gen3 x4 M.2

With two NVMe PCIe Gen3 x4 M.2 connectors onboard, GIGABYTE brings to the user PCI-Express connectivity for SSD devices. Delivering up to 32 Gb/s data transfer speed per connector, the dual M.2 provides an ideal storage solution as it also supports RAID modes.

U.2 Adaptor (NVMe PCIe Gen3 x4)

NVMe Performance for PCIe SSDs

The new Intel 750 series SSDs offer an incredible increase in performance over SATA drives. Using the NVMe protocol which takes advantage of the fast bandwidth of PCIe Gen3 x4 lanes (32 Gb/s), the drives are a clear advantage for users looking to boot their OS faster, load their games in a flash and access large files without waiting. By implementing the U.2 Adaptor to support the 2.5” Intel 750 Series drive, GIGABYTE ensures that the users can benefit from the best performance.
