GIGABYTE UD series motherboards use an 11+1 phase digital PWM + Low RDS(on) MOSFETs design to support the latest 10-core Intel® Core™ CPUs by offering incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability. We are offering a tested and proven platform that ensures proper compatibility with profiles up to 4500MHz and beyond. All users need to do to attain this performance boost is to ensure that their memory module is XMP capable and that the XMP function is activated and enabled on their GIGABYTE motherboard. For most prosumers and gamers, high bandwidth storage and high-performance graphics card are critical for their applications. To support most cutting edge devices, this motherboard uses the groundbreaking PCIe 4.0-grade hardware design.
