GIGABYTE's leading 12 phase power VRM design utilizes the highest caliber components to provide unadulterated, smooth power delivery for the CPU. GIGABYTE’s 12 phase power design enables better delivery of power to supercharge your system, giving power users unparalleled overclocking ability and lower temperatures to reach maximum performance levels. The 12 phase power VRM has been designed and engineered to deliver fast transient response times through quick and seamless power delivery during extensive CPU loading variations. In addition, heat from the VRM is effectively reduced by spreading the load between the 12 power phases, resulting in a cooler and more stable platform.
On/Off Charge Support
GIGABYTE On/Off Charge technology that enables faster iPhone, iPad and iPod Touch charging. A derivative of GIGABYTE's highly acclaimed 3x USB Power feature, On/Off Charge technology allows iPhone, iPad and iPod touch devices to draw more current from GIGABYTE motherboard USB ports than standard USB ports allow, with the added benefit that the PC can be on, in standby mode or even off...more *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-UD3P 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.
* USB 3.0 10x performance is a maximum theoretical value. Actual performance may vary by system configuration.
SATA 6 Gbps Support
Yet another onboard feature of GIGABYTE P55A motherboards are Marvell’s new 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 P55A series 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
GIGABYTE motherboards feature a 3x USB power boost, delivering greater compatibility and extra power for USB devices. GIGABYTE’s unique USB power design is also able to efficiently regulate output over the full voltage range, which greatly enhances USB device compatibility. In addition, dedicated lower resistance fuses ensure lower voltage drops, and provide more stable and plentiful power delivery.
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

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. So, 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

I have never bought a Gigabyte mobo but this one does impress me. It has SATA3 and USB3.0 support so it is ready for future HDD and peripheral upgrades. The only thing that I don't like is based on Intel, LGA1156 is short-lived, but it cannot really blame on the mobo. You cannot ask too much for a ~$150 mobo about future-proof.
Overall a good Mobo But next time I would look deeper into buying a different Gigabyte Mobo Over this one. I like Gigabyte but this Mobo had to many negatives for me to buy it again. WORKS FINE, everything NECESSARY is on it but the IO plate Glitch REALLY annoys me.
So I got this mobo to go with an i5 750 and a Radeon HD 5770 gpu....it installed very easily. Flashing the bios for an update to F10 was easy as pie, and with the dual bios feature, I wasn't worried about doing it. I used sbios for the update . I really have no complaints, lots of room for after market coolers around the cpu and memory slots. The only thing to watch out for is to make sure you know what rev. your mobo is. I thought I was buying a rev 2.0 when in fact mine was a 1.0. No big deal, but the update s are different and the list of supported memory modules is also different. I would recommend this to anyone building a slightly above mid-line multi-tasking computer.
Solid Board. Colour scheme is kind of funky but its fine. I have not had any problems with it yet. Used it in a friend's build. Used G skill 1.5 ram and i7 860. Have not tried over clocking. Everything worked from the get go without any hitches. I disabled USB 3.0 and sata 3.0 in the bios.
Bought this three months ago when I was building my new rig. Works perfectly with my i5 750 using the lga1156 socket. Nice price point, excellent for what I needed. Also glad that I'll be able to use usb 3.0 when that comes out.
