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.

The revolutionary GIGABYTE 3D BIOS application is based on our new GIGABYTE UEFI DualBIOS™ technology and is available to consumers in two new exclusive modes of interaction never before seen in a BIOS environment. GIGABYTE has re-drawn the traditional BIOS experience providing mainstream and enthusiast users with a choice of unique and powerful graphical interfaces.

UEFI DualBIOS™ Technology
At the heart of this exciting 3D BIOS technology is a pair of 8MB physical BIOS ROMs containing GIGABYTE's exclusive in-house designed UEFI BIOS technology. With a superior graphical interface capable of 32-bit color imaging and fluid user-friendly mouse navigation, UEFI DualBIOS™ makes BIOS configuration a new and exciting experience for novice and experienced users alike. UEFI BIOS also brings native support for large hard drives on 64-bit operating systems.

3D Mode
Designed to provide an extremely streamlined and user-friendly BIOS environment, GIGABYTE's exclusive 3D mode offers a fully interactive and illustrative GUI that allows users to easily and intuitively make key adjustments to the UEFI BIOS settings for optimum performance. 3D Mode allows novice or casual users to more clearly understand the areas of the motherboard that are being affected through the BIOS settings, gaining a clearer understanding of the BIOS functionality.

Advanced Mode
Advanced mode provides a more comprehensive UEFI BIOS environment that is designed specifically for overclockers and power users who want maximum control over their PC's hardware. GIGABTYE's signature M.I.T. tuning technology can be found alongside fully configurable parameters for GIGABTE's all new digital 3D Power engine. In short, advanced mode combines the signature GIGABYTE BIOS expertise you’ve come to expect, wrapped a slick, new and optimized graphical UEFI interface.

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.

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 32GB of DDR3 1600 memory, the G1.Assassin 2 motherboard gives you the ultimate performance for today's memory-intensive 3D games.

With 2 kinds data transfer mode, GIGABYTE Bluetooth 4.0 and WiFi Card providing spec 300 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 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.

GIGABYTE motherboards boast SuperSpeed USB 3.0 technology made possible through an additional onboard host controller. With superfast transfer rates of up to 5 Gbps, users are able to experience a theoretical 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.

GIGABYTE motherboards are High-Speed SATA Revision 3.0 compatible, 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, they offer even faster data transfer rates of up to a theoretical 4x the speed of current SATA interfaces.

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.
