GA-X79-UD5 (rev. 1.1)

GIGABYTE X79 series motherboards are designed to unite unrivalled desktop PC performance with a new level of flexibility and hardware control. Based on the latest Intel^® X79 Express Chipset, supporting the new LGA 2011 Intel^® Core™ i7 processors, GIGABYTE X79 series motherboards bring DIY builders to a new area of performance-oriented computing.

GIGABYTE X79 series motherboards are the first to take advantage of the exclusive GIGABYTE 3D Power, an all new hardware and software-based Digital Power Engine for both the PWM and Memory that delivers unprecedented power delivery control.

All New Digital Power Control for the CPU and Memory
Utilizing a brand new Digital PWM controller, GIGABYTE's 3D Power features precise Auto Voltage Compensation to deliver a steady flow of power to the CPU and memory no matter the loading. This all new, all digital power system provides enthusiast users with exceptional control over the overclocking potential of their GIGABYTE X79 motherboard.
GIGABYTE is the first in the industry to utilize digital memory controllers for not only the Memory, but VTT and VSA, for real-time monitoring and adjusting. Digital memory control allows users to monitor and record DDR power and current in real-time while gaming, overclocking or at idle. Users can also set OVP (Over Voltage Protection) to safeguard your memory, adjust memory Load-line Calibration to fix memory vdrooping for a quicker response time and adjust memory PWM frequency on-the-fly.

		Users can now enjoy a fully interactive 3D utility that facilitates adjustment of the 3 dimensions that control the power delivery to your CPU and Memory: Voltage, Phase and Frequency. These parameters are crucial to how the digital PWM supplies power to critical areas of the motherboard and can help users quickly obtain the highest, most stable overclock.
		3D Power: Voltage Control Voltage parameters can be modified within 3D Power, including load line calibration the of CPU. By adjusting load line calibration, Vdrooping can be avoided, maintaining optimal voltages levels despite increasing current levels. OVP (over voltage protection) can also be adjusted to change default protection range of the CPU, memory controller, VTT and system memory.
		3D Power: Phase Control Users can calibrate OCP (Over Current Protection) for the CPU, integrated memory controller and system memory power levels. This allows the Phase control to deliver even more power to the system when needed.
		3D Power: Frequency Control GIGABYTE's digital PWM allows for adjustable frequency control via the International Rectifier (IR3567) PWM controller. 3D Power frequency control allows users to change the PWM controller frequency so that the CPU VRM can adjust power delivery speeds more quickly. Users can also adjust the PWM spectrum or maximum and minimum overall frequencies.

With a potential data bandwidth of up to 25GB/Sec and 256 Bits memory addressing, the Intel^® X79 platform offers unrivalled memory performance. Supporting up to 64GB of DDR3 1600 memory (X79-UD5 only), GIGABYTE X79 series motherboards give you the ultimate performance for today's memory-intensive applications.

The GIGABYTE motherboard is fully configured to provide gamers with the latest Gen.3 PCI Express technology, delivering maximum data bandwidth for forthcoming discrete graphics cards.
* PCIe Gen. 3 is dependent on CPU and expansion card compatibility.

The GIGABYTE X79-UD5 is equipped to help extreme gamers see the enemy from distance, regardless of how bloody the battlefield, offering the utmost graphics flexibility and upgradeability with multiple GPU support, that includes three PCI Express slots for both AMD CrossFire™ X and Nvidia SLI™ technologies in 3-way discrete card configurations. The GIGABYTE X79-UD5 motherboard delivers maximum FPS, allowing gamers to see more clearly, aim faster, and move more quickly.

OC-Dual BIOS features a unique back-panel BIOS switcher and LED indicator, allowing users to select one BIOS for normal use, and another for specifically designated for overclocking. This means that if your overclocking configuration suffers from instability, you can easily revert to your stable settings if needed. With OC-Dual BIOS, users can also easily compare two different BIOS versions, a very useful feature when users want to update to a new BIOS, but don't want to lose their original settings.

GIGABYTE X79 motherboards take advantage of the most comprehensive PCI Express data bus ever seen on a desktop PC platform. The Intel^® X79 platform integrates all PCI Express lanes in to the CPU, resulting in lower latency and even faster performance for the latest discrete GPU and multi-GPU configurations.

With 2 kinds data transfer mode, GIGABYTE Bluetooth 4.0 and WiFi Card providing spec 150 Mbps transfer rates, 802.11n supports the latest WiFi specifications for better signal coverage, and featuring the newest Bluetooth 4.0, you will not suffer from signal loss like before.

GIGABYTE X79 series motherboards feature GIGABYTE 333 Onboard Acceleration , a range of the latest technologies that are designed help speed up data transfer, including SuperSpeed USB 3.0 technology, SATA Revision 3.0 (6Gbps) technology and an unprecedented 3x USB power boost on all USB ports for more power hungry USB devices.

GIGABYTE X79 series motherboards feature ON/OFF Charge, a unique GIGAYTE technology which allows you not only to charge your iPhone, iPad or iPod Touch, but also allows you to Quick Charge it. As an added bonus, it can even be charged when your PC is turned off, so even if you forget to plug it into your charger after you've synced up your music, it will be fully charged when you need it.

* 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 X79 motherboards are equipped with the highest quality components that guarantee lower system temperatures, improved energy efficiency and enhanced stability for overclocking. GIGABYTE Ultra Durable™ 3 design features 2 ounces of copper for both the power and ground layers which dramatically lower system temperature. GIGABYTE's Ultra Durable™ 3 also features Japanese made solid capacitors, PowerPAK MOSFETs and Ferrite Chokes which combine to offer lower motherboard temperatures, less wasted power and extended product longevity.
