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.

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 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.

P55A-UD7 support Intel Core™ i7/ Core™ i5 processors delivering native support for DDR3 memory up to 2600+MHz by the enhanced design of GIGABYTE, Intel Core™ i7/ Core™ i5 processors feature the memory controller integrated directly into the processor die, rather than as part of the Northbridge as in previous generations, allowing for faster memory performance.

Dynamically reroutes power to improve performance For situations when all cores are not needed for a particular workload, Intel Turbo Boost Technology powers down the idle cores and dynamically reroutes the power to the active cores, boosting their performance without wasting power. This allows the active cores to achieve significant overclocks.

GA-P55A-UD7 motherboard now features the revolutionary new GIGABYTE Hybrid Silent-Pipe 2, a fusion thermal solution that combines GIGABYTE’s proprietary screen cooling technology, external heat sink and liquid cooling with chipset water block to deliver maximum thermal performance.

• Unique Screen Cooling thermal design effectively reduces the temperature around the CPU zone, and removes the heat between NB and SB area.
• Liquid Cooling system featuring special waterblock design with an enlarged dissipating surface area for enhanced heat dissipation and optimum flow-rate.
• High-Precision die forming technology utilized to increase the thermal conductivity of the material that makes up the heat sink.
• High performance Copper Heat Pipe with sintered process designed for ultra efficient thermal conductivity.
• External Heat Sink design utilizing a convection slot at the back of the chassis to increase thermal dissipation.

GIGABYTE Hardware Overvoltage Control ICs featuring more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control, which means there is no delay compared to the GPIO controller in past implementations. In addition, GIGABYTE's Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.
