*携帯電話の機種によっては、クイック充電を有効にするためには、PCがS4/S5モードに入る前に携帯電話をPCに接続する必要があります。 充電時間は機種によって異なります。

This motherboard designs with Split Power Plane, 4+1 phase VRM to support AMD the latest 45nm AM3 Phenom™II/ Athlon™II processors, delivering the great performance enchantment to system and ultimate scalability hardware expending.

GIGABYTEは、2011年以降のマザーボードすべてが順次HDオーディオコーデックの対応を基準としました。
マルチチャネルHDオーディオをサポートする高性能なオーディオコーデックは、信号対雑音比（*SNR）108dBの優れた再生品質でBlu-rayを存分にお楽しみ頂けます。
（*SNRは信号の量に対するノイズの量で単位はdB[デシベル]で表されます。SNRが高ければ高いほど信号に対するノイズの量が少ないことがわかります）

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 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.
Note: Turbo XHD function only enabled for the SATA3 ports provided by AMD 800series with SB850 Chipset.

The GIGABYTE AMD 800A series motherboards support the latest generation SuperSpeed USB 3.0 technology made possible through an onboard NEC uPD720200 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 NEC 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.

GIGABYTE独自の「3倍USB電源」技術は、USBデバイスが必要とする電源を約3倍速で供給する技術です。独自で設計したUSB電源設計が電圧範囲におけるアウトプットを調整し、低抵抗の専用ヒューズが電圧降下の値を低く保つため、より安定的に電力をデバイスに送ることができます。

Yet another onboard feature of GIGABYTE AMD 800A series motherboards are integrated the latest AMD SB850 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 800A series motherboards offer even faster data transfer rates of up to 4x the speed of current SATA interfaces.

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.
