The GA-MA790XT-UD4P introduces revolutionary GIGABYTE Ultra Durable 3 technology on latest AMD socket AM3 platform with featuring 2 oz copper PCB and further helps to reduce the system temperature and dramatically enhance the performance. Based on AMD 790X chipset, the GA-MA790XT-UD4P supports new generation of 45nm AMD Phenom II series processors, integrated DDR3 memory controller, HyperTransport™ 3.0 technology links and dual PCI Express 2.0 graphics interfaces (running at x8 and x8) for ATI CrossFireX support. With the innovative GIGABYTE Easy Energy Saver technology, the MA790XT-UD4P is able to provide user friendly computing, reach the maximum system performance easily while still able to save the power and environment in real life at the same time.


EC AOD-ACC is described as Embedded Controller for AMD OverDrive- Advanced Clock Calibration, which is the newest feature comes from AMD SB750/ SB710 SouthBridge chip, destined for the AMD Black Edition CPU to be overclocked through BIOS setting or AMD OverDrive™ utility further than it was previously possible.
* Please apply sufficient cooling to CPU VRM zone when ACC function is enabled.
* Please be noticed that GIGABYTE’s product warranty does not cover damages caused by overclocking.
AMD OverDrive Support
The AMD OverDrive™ utility is provided by AMD, offering high-end users the ability to maximize the capability, flexibility, and adjustability of the platforms utilizing AMD processors, sockets, and chipsets.
* For download site of AMD OverDrive™, please visit AMD official website for details: [ Ссылка ]
** The support condition of this utility may vary by models(chipsets).
ATI CrossFireX™ support
With support for latest ATI CrossFireX™ technology, GIGABYTE pushes the envelope once again by delivering highly optimized performance and flexibility demanded for power users and extreme gaming enthusiasts. Designed to provide unmatched multi-GPU support with dual PCI-E connectivity, the GA-890GPA-UD3H allows users to take advantage of the ultra smooth 3D rendering, blazing-fast frame rates and enhanced visual quality possible.
Ultra Durable 3
GIGABYTE Ultra Durable 3 design, featuring 2 ounces of copper for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. GIGABYTE’s Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2oz Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking.
Benefits of 2 oz Copper PCB
• Cooler than traditional motherboards
• Enhanced durability
• Improved energy efficiency
• Greater margins for overclocking...more
2X Lower Impedance

Doubling the amount of copper lowers the PCB impedance by 50%. Impedance is a measure of how much the circuit impedes the flow of current. The less the flow of current is impeded, the less amount of energy is wasted. For GIGABYTE Ultra Durable 3 motherboards, this means total PCB electrical waste is reduced by 50%, which also means less heat is generated. 2 ounces of copper also provides improved signal quality, providing better system stability and allowing for greater margins for overclocking.
