GIGABYTE 3D Power (patent pending)
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.

GIGABYTE 3D Power(patent pending) Utility
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

GIGABYTE 3D BIOS(patent pending)
The revolutionary GIGABYTE 3D BIOS application is based on our new GIGABYTE UEFI DualBIOSTM 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 DualBIOSTM 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 DualBIOSTM 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.

GIGABYTE Bluetooth 4.0 and WiFi Card
