The motherboard or mainboard is the component that connects all the different parts of your computer. Often it has some integrated components like a sound card, enabling your computer to play sound, or a network card, to connect your computer to the network. The standard form factor (size) for motherboards is ATX, you need at least a midi-tower to fit one of those in. Micro-ATX motherboards are often more complete and have more onboard devices, like a video board and fit in smaller cases, but are generally less expandable.

USB 3.0 Support

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 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.

Like any other LGA 1156 motherboard, the P55A-UD6 is limited to eight memory banks via the processor’s dual-channel DDR3 controller, so that typical high-end configurations of 8GB or 16GB are possible via four 2GB or 4GB modules. But Gigabyte has found a trick, a little slight-of-hand perhaps, to make it appear...
