Gigabyte GA-X79-UD5 Intel X79 Socket 2011 E-ATX 8x Quad Channel DDR3-2133 PCI-E3.0 RAID 3-way Crossfire 3-way SLI 1394 eSATA USB3.0 SATA3

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^TM i7 processors, GIGABYTE X79 series motherboards bring DIY builders to a new area of performance-oriented computing.

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.
