  • On/Off Charge Technology
    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...more
    Note: Due to certain mobile phone limitations, users may need to connect the mobile phone to their PC before the PC enters S4/S5 mode to enable a quick charge from non On/Off Charge USB ports. Charging results may vary by model.

  • GIGABYTE P55A-UD7 Obtains USB 3.0 Motherboard Certification Officially
    The GIGABYTE P55A-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.

  • SATA 6 Gbps Support
    Yet another onboard feature of GIGABYTE motherboards are Marvell's SE9128 chips for high-speed SATA Revision 3.0 compatibility, delivering superfast 6Gbps link speeds for twice the data transfer rates of SATA Revision 2.0 (3 Gbps). When used in RAID 0 (Stripe) mode, GIGABYTE motherboards offer even faster data transfer rates of up to 4x the speed of current SATA interfaces.

    * SATA3 RAID 0 4x and SATA3 2x performance are maximum theoretical values. Actual performance may vary by system configuration.
    * SATA3 SSDs are not recommended for use in RAID 0 mode on Marvell SE9128 ports.
  • 3‎x USB Power Boost
    3x USB Power Boost - 3x USB Power Boost da GIGABYTE, fornece maior compatibilidade e energia extra para dispositivos USB. O USB power exclusivamente desenvolvido pela GIGABYTE regula de forma eficiente a saída de energia, aumentando a compatibilidade de dispositivos USB. Além disso, fusíveis dedicados de baixa resistência garantem perdas menores de voltagem, garantindo assim um fornecimento de energia estável e eficiente.
  • Ultra Durable 3

    Ultra Durable 3
    GIGABYTE Ultra Durable 3 design, featuring 2 ounces of copper for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. GIGABYTE's Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2oz Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking...more

  • Hotkey OC
    GIGABYTE Hotkey OC allows users to create and save various profiles that can be adopted for different benchmarks. Hotkey OC then allows users to jump between these profiles on the fly so that the best profile for each segment within the benchmark can be used to optimize scores and boost overall performance. For example, when running 3DMark 06, the 1st profile might be optimized for graphics, and can be used for the first two graphics tests, then, the next two tests can utilize the 2nd profile which might be optimized for CPU tests, and one could jump back to the 1st profile again for the final two graphics (shader) tests...more
