To enable AM3+ AMD FX-Series CPU support, please update your motherboard with the most current BIOS found in your motherboard’s download section.
Introduction

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.
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.
GIGABYTE Touch BIOS™ (Patent Pending)
An Innovative New Way to Modify BIOS Settings
Navigating
through the BIOS to change system settings can be a daunting task for
users not familiar with control “F”functions and mouse-less navigation.
While some EFI BIOS try to address this with a mouse friendly
environment, many implementations still lack a certain ease-of-use
necessary for most people. With GIGABYTE Touch BIOS™, GIGABYTE engineers
have completely re-imagined how users can interact with their BIOS,
allowing for a more intuitive user experience. In fact, with a touch
screen monitor, GIGABYTE Touch BIOS™ is as easy to use as most apps on
your iPhone.

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.
