SATA 6 Gbps Support
Yet another onboard feature of GIGABYTE AMD 900 series motherboards are integrated the latest AMD SB950 chip for high-speed SATA Revision 3.0 compatibility, delivering 6 ports native superfast 6Gbps link speeds for twice the data transfer rates of SATA Revision 2.0 (3 Gbps) and RAID 0, 1, 5, 10 support. When used in RAID 0 (Stripe) mode, GIGABYTE AMD 900 series motherboards offer even faster data transfer rates of up to 4x the speed of current SATA interfaces.

USB 3.0 Support
The GIGABYTE motherboards support the latest generation SuperSpeed USB 3.0 technology made possible through an onboard USB3.0 host controller. With superfast transfer rates of up to 5 Gbps, users are able to experience an almost a 10x improvement over USB 2.0. Additionally, backwards compatibility with USB 2.0 assures users of long term use of their legacy USB 2.0 devices. The onboard SuperSpeed USB 3.0 technology also provides new power management features that include increased maximum bus power and device current draw to better accommodate power-hungry devices.

3x USB Power Boost
GIGABYTE motherboards feature a 3x USB power boost, delivering greater compatibility and extra power for USB devices. GIGABYTE’s unique USB power design is also able to efficiently regulate output over the full voltage range, which greatly enhances USB device compatibility. In addition, dedicated lower resistance fuses ensure lower voltage drops, and provide more stable and plentiful power delivery.

Multi-display support with 2 way SLI™ and 2 way CrossFireX
Flexible graphics capabilities - Up to 2 VGA cards are supported for either 2 way CrossFireX™ or 2 way SLI™ action (running at two x16 bandwidth), delivering the ultimate in graphics performance for gaming enthusiasts who demand the highest frame rates without compromising on resolution.

AMD OverDrive Support
The AMD OverDrive™ utility is provided by AMD, offering high-end users the ability to maximize the capability, flexibility, and adjustability of the platforms utilizing AMD processors, sockets, and chipsets.

Dual Channel DDR3 2000+ MHz
Delivering native support for DDR3 memory up to 2000MHz, GIGABYTE Ultra Durable 3 series motherboards allow users to easily reach higher memory frequencies at lower voltages; achieving higher memory performance with lower power consumption to run even the most memory intensive applications such as high-definition video and 3D games with ease.

108dB Signal-to-Noise ratio playback
GIGABYTE strongly believes that in 2011, HD audio playback is a standard specification, and as such, we have made Blu-ray audio playback a standard for all of our motherboards.
All of GIGABYTE's 2011 motherboards feature higher capability audio solution with 108dB Signal-to-Noise ratio (SNR) playback quality to deliver high-performance, multi-channel HD audio. SNR is a comparison of the amount of signal to the amount of noise such as hiss present in the signal (expressed in Decibels). A higher SNR equals a better audio experience. For example, 108dB, is a high audio specification, as this means the audio signal is 108dB higher than the level of the noise.

DualBIOS™ 3TB+ HDD Support (Hybrid EFI Technology)
Hybrid EFI Technology combines the benefits of GIGABYTE's mature BIOS platform including stability and compatibility with 3rd party products with 3TB+ HDD support from EFI technology, allowing GIGABYTE to offer the best of both worlds through a quick and easy BIOS update using GIGABYTE's @BIOS utility that is freely available from the GIGABYTE website.
GIGABYTE DualBIOS™ is a patented technology that automatically recovers BIOS data when the main BIOS has crashed or failed. Featuring 2 physical BIOS ROMs integrated onboard, GIGABYTE DualBIOS™ allows quick and seamless recovery from BIOS damage or failure due to viruses or improper BIOS updating. In addition, GIGABYTE DualBIOS™ now supports 3TB+ (terabyte) hard drive booting without the need for partitioning, and enables more data storage on a single hard drive.

Turbo XHD- Full Automatic RAID 0/Stripe
GIGABYTE Turbo XHD provides a quick and easy way to boost your hard drive performance. Just via the latest BIOS update, Turbo XHD will automatically enabled when the system detecting 2 new SATA3 HDDs and providing users effortlessly to set up a RAID 0/Strip configuration.
