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.

GIGABYTE Ultra Durable™ 4 motherboards embrace a range of exclusive technologies that guarantee DIY PC builders the absolute best protection for their PC, with built-in features that prevent common malfunction threats.

 

With a superior graphical interface capable of 32-bit color imaging and fluid user-friendly mouse navigation, UEFI DualBIOS™ makes BIOS configuration a new and exciting experience for novice and experienced users alike. UEFI BIOS also brings native support for large hard drives on 64-bit operating systems.

 

 

Flexible graphics capabilities - Up to 2 VGA cards are supported for either 2 way CrossFire 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.

 

 

GIGABYTE 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.

 

 

The 990FXA-UD3 motherboard is designed to offer a stable, high-speed platform for delivering amazingly fast data transfer via the GIGABYTE 333 onboard acceleration technologies. Featuring the USB3.0 controller, AMD 900 series motherboards allow users to take advantage of super fast USB transfer rates of up to 5Gbps, delivering 10x faster data transfer compared to USB 2.0. Utilizing the industry's first Serial ATA Revision 3.0 solution via AMD SB950 chipset, GIGABYTE AMD 900 series motherboards offer native 6 ports of next generation high speed data storage devices support with data transfer speeds of up to 6 Gbps with RAID 0, 1, 5, 10. The AMD 900 series motherboards introduce a unique hardware design with lower resistance fuses for ensuring lower voltage drops and providing more stable and plentiful power delivery. All USB ports also benefit from a 3x power boost for better power delivery to power hungry USB devices.

GIGABYTE's AMD motherboards are ready to support new generation of 32nm AMD AM3+ multi-core processors, delivering the very best platform for multitasking, multimedia and high performance gaming.

 

 

This motherboard designs with Split Power Plane, 8+2 phase VRM to support AMD the latest 45nm AM3 Phenom™II series processors, delivering the great performance enchantment to system and ultimate scalability hardware expending.

 

 

 

GIGABYTE motherboards feature GIGABYTE 333 Onboard Acceleration , a range of the latest technologies that are designed help speed up data transfer, including SuperSpeed USB 3.0 technology, SATA Revision 3.0 (6Gbps) technology and an unprecedented 3x USB power boost on USB ports for more power hungry USB 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.

 

 

Delivers vivid surround sound for music, movies, and games, using two to eight speakers or any set of headphones.

 

 

GIGABYTE On/Off Charge technology allows you to charge your iPhone, iPad and iPod Touch regardless of whether your PC is on, in standby mode or even off. A derivative of GIGABYTE's highly acclaimed 3x USB Power feature, On/Off Charge enables devices to draw more current from GIGABYTE motherboard USB ports than standard USB ports allow, so that charging from your PC can be as fast as with a charger.

 

The ErP (also known as Energy-Related Products Directive) is part of the European Union's environmental regulations policy. It is based on concern for the environmental as the proliferation of electronic devices continues, and how to improve energy efficiency for a better and greener life. GIGABYTE supports ErP and produces motherboards that help you effectively improve system efficiency.
