The Gigabyte exclusive Ultra Durable technology utilizes a range of design and components to ensure maximum durability, reliability and protection against humidity, power surges, electrostatic discharge, and even BIOS failure. The Realtek ALC1150 codec in concert with premium audio capacitors and dedicated audio hardware separation brings onboard audio far beyond your expectation to an amazing 115dB SNR. The USB 3.0 and SATA III will save you time while transferring large libraries of files, while two eSATA 6Gbps facilitates data backup. Additionally, this motherboard features thermally-optimized heat sink on the PWM area and chipset, enabling a cool look and cool operation under extreme loading level.

General information

Extreme Multi-GPU Support

Flexible graphics capabilities supported for either 2-Way CrossFire or 2-Way SLI action, delivering the ultimate in graphics performance for gaming enthusiasts who demand the highest frame rates without compromising on resolution.


General information

GIGABYTE Digital Power Engine

GIGABYTE Ultra Durable motherboards take advantage of an exclusive Digital PWM controller array, to deliver maximum and stable power to latest processors. Using digital controllers means that more precise power delivery to the motherboard's most power hungry and energy sensitive components is possible. This Digital Power system, with Precise Auto Voltage Compensation to make real-time adjustments and deliver a steady flow of power to the system, no matter the loading. This all new, digital power system provides enthusiast users with exceptional control over the overclocking potential of their GIGABYTE motherboard.


General information

Realtek ALC1150 115dB SNR HD Audio with Built-in Rear Audio Amplifier

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. The ALC1150 provides ten DAC channels that simultaneously support 7.1-channel sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. Two stereo ADCs are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies. The ALC1150 incorporates Realtek proprietary converter technology to achieve Front differential output 115dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 104dB SNR recording (ADC) quality.


General information

High Quality Audio Capacitors

GIGABYTE Ultra Durable™ motherboards use high quality Nippon Chemicon ARE series audio capacitors. These professional audio capacitors deliver the highest quality sound resolution and sound expansion to create the most realistic sound effects for user experience.


General information

Dedicated Audio Hardware Zone

Separation on the PCB layer protects the board's sensitive analog audio components. This motherboard also features separated analog and digital ground to protect against Electromagnetic Interference (EMI).


General information

eSATA Ports for easy data manipulation on external devices

Featuring with two external SATA (eSATA) ports on rear panel, it provides smart setup and hot-plug functionality allowing easier data backup and content manipulation on external storage devices.


2x Copper PCB Design (2 oz Copper PCB)

General information

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.

Humidity Protection with New Glass Fabric PCB

General information

There is nothing more harmful to the longevity of your PC than moisture, and most parts of the world experience moisture in the air as humidity at some point during the year. GIGABYTE motherboards have been designed to make sure that humidity is never an issue, incorporating a new Glass Fabric PCB technology that repels moisture caused by humid and damp conditions. Glass Fabric PCB technology uses a new PCB material which reduces the amount of space between the fiber weave, making it much more difficult for moisture to penetrate compared to traditional motherboard PCBs. This offers much better protection from short circuit and system malfunction caused by humid and damp conditions.

General information

Long Lifespan Solid Capacitors

GIGABYTE motherboards integrate the absolute best quality solid state capacitors that are rated to perform at maximum efficiency for extended periods, even in extreme performance configurations. This provides peace of mind for end users who want to push their system hard, yet demand absolute reliability and stability.


General information

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.


General information

ESD Protection for USB and LAN

GIGABYTE motherboards raise the bar in terms of protecting your system, providing advanced electrostatic discharge (ESD) protection for both your Ethernet LAN and USB ports, both common sources of ESD-related failures. Each LAN and USB port is paired with a dedicated protection filter that can withstand high electrostatic discharges, protecting your system from common electrical surges and even direct lighting strikes.


Power Failure Protection with Anti-Surge IC

General information

GIGABYTE Ultra Durable™ motherboards also feature special anti-surge ICs that protect your motherboard, and your PC from any surge in power delivery that may occur, helping to ensure that your PC is equipped to deal with any potentially irregular and inconsistent power delivery.

All New Heat Sink Design

General information

GIGABYTE motherboards feature new heat sink designs that offer uncompromisingly efficient cooling on key areas of the motherboard including the PWM area and chipset (PCH). GIGABYTE motherboards offer cooling support of the crucial PWM area so even the most aggressive and extreme configurations will be kept well within optimal thermal parameters.
