High Definition Audio Design

The Realtek ALC1150 is a high-performance multi-channel high definition audio codec that delivers an exceptional audio listening experience with up to 115dB SNR, ensuring users get the best possible audio quality from their PC.

High Quality audio capacitors deliver the highest quality sound resolution and sound expansion to create the most realistic sound effects for professional gamers.

Ambient LED

GIGABYTE motherboards feature LED lighting for the audio guard path, providing a cool, custom look to your rig. Not only does the Audio Noise Guard protect the board's sensitive analog audio components, but its LEDs can also be programed to beat at the rhythm of the music you are listening to, or pulse at a soothing pace to create a great atmosphere to enhance the environment of your game, movie or music.

Clean, low-noise power for your Digital-to-Analog Audio converter 

GIGABYTE USB DAC-UP provides clean, noise-free power delivery to your Digital-to-Analog Converter. DACs can be sensitive to fluctuations in power from the other USB ports, which is why GIGABYTE USB DAC-UP takes advantage of an isolated power source that minimizes potential fluctuations and ensures the best audio experience possible.

Killer™ E2200 Gaming Network

GIGABYTE G1™ Gaming motherboards feature the Killer™ E2200, a high-performance, adaptive gigabit Ethernet controller that offers better online gaming and online media performance compared to standard solutions.

2x Copper PCB Design (2 oz Copper PCB)

GIGABYTE's exclusive 2X Copper PCBs design provides sufficient power trace paths between components to handle greater than normal power loads and to remove heat from the critical CPU power delivery area. This is essential to ensure the motherboard is able to handle the increased power loading that is necessary when overclocking. 

GIGABYTE Patented DualBIOS™ (UEFI) Design

GIGABYTE Ultra Durable™ motherboards feature GIGABYTE DualBIOS™, an exclusive technology from GIGABYTE that protects arguably one of your PC's most crucial components, the BIOS. GIGABYTE DualBIOS™ means that your motherboard has both a 'Main BIOS' and a 'Backup BIOS', making users protected from BIOS failure due to virus attack, hardware malfunction, improper OC settings or power failure during the update process. 

GIGABYTE App Center Including EasyTune™ and Cloud Station™ Utilities

GIGABYTE APP Center gives you easy access to wealth of GIGABYTE apps that help you get the most from your GIGABYTE motherboard. Using a simple, unified user interface, GIGABYTE APP Center allows you to launch all GIGABYTE apps installed on your system.

  GIGABYTE EasyTune ™ App
GIGABYTE's EasyTune™ is a simple and easy-to-use interface that allows users to fine-tune their system settings or adjust system and memory clocks and voltages in a Windows environment. With Smart Quick Boost*, one click is all it takes to automatically overclock your system, giving an added performance boost when you need it the most.
* Feature may vary by CPU models.
