ASRock XFast USB Technology redefines the new standard in high performance computing. Proving once again to be the pioneer in motherboard industry, ASRock XFast USB Series Motherboards integrate with the latest XFast USB Technology which delivers the world's fastest USB data transfer speed. According to the below graph, it shows that the ASRock XFast USB technology can even boost USB 3.0 performance up to 229.08% Intel Quick Sync Video saves valuable time for PC users who want to create and edit video, synchronize it with other devices, and share it-at home and on the internet. Intel Quick Sync Video uses hardware on the processor, instead of software, to accelerate video encoding. Enjoy the ultimate 3D visual experiences-seamlessly-from your PC. Now you can watch your favorite 3D movies with Blu-ray Stereo 3D playback using active shutter 3D glasses. It delivers it all in 1080p full, high-definition resolution on your TV over HDMI 1.4. Intel Clear Video HD Technology (Intel CVT HD) enables rich media experiences with picture perfect images by using a host of advanced graphics technologies that support optimized, high-definition video playback and sharp image quality. Intel HD Graphics is now built right into the processor.


This integration means lower latencies and leads to superior mainstream gaming and enhanced 3D experiences. Intel Advanced Vector Extensions (Intel AVX) gives more computing power to application developers with a new, 256 bit instruction set extension to Intel SSE. ASRock Extreme Tuning Utility (AXTU) is an all-in-one software to fine-tune different features in an user-friendly interface, which includes Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hardware Monitor, it shows the major readings of your system. In Fan Control, it shows the fan speed and temperature for you to adjust. In Overclocking, you are allowed to overclock the GT frequency which helps to boost up the graphics performance and some voltage settings for optimal system performance. In OC DNA, you can save your OC settings as a profile and share with your friends. Your friends then can load the OC profile to their own system to get the same OC settings. In IES (Intelligent Energy Saver), the voltage regulator can reduce the number of output phases to improve efficiency when the CPU cores are idle without sacrificing computing performance. It is the smart start page for IE that combines your most visited web sites, your history, your Facebook friends and your real-time newsfeed into an enhanced view for a more personal Internet experience.
