This motherboard supports HDMI (High-Definition Multimedia Interface) which is an interface standard for transferring uncompressed video data & delivering multi-channel audio through a single cable. Both video & audio data signals transferred through the HDMI interface is digital without being converted into analog, therefore it delivers the richest pictures & the most realistic sounds. Bitcoin is a digital currency that is recognized globally, & this motherboard is specifically designed for mining bitcoins. This robust mining machine is built with the best materials to help miners hit jack pot. Compared to other competitors' 3 power phase design on the motherboards, ASRock adds a finishing touch by implementing 4 power phase design & sturdy components for delivering smoother power to the CPU, thus enhancing the motherboard's performance & stability at lower temperatures. ASRock is determined to use high quality materials to build the motherboards that's why all the capacitors on this motherboard are built with 100% solid capacitors. These solid capacitors bring long lasting durability & ultra stable performance. Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently & smoothly, so that the stability & lifespan of the motherboard is greatly enhanced. It shortens the loading time of previously visited websites, making web surfing faster than ever. & it also boosts the speed of Adobe Photoshop 5 times faster. Another advantage of ASRock XFast RAM is that it reduces the frequency of accessing your SSDs or HDDs in order to extend their lifespan. Fast boot is so fast that it is impossible for users to enter the UEFI setup utility during POST. Therefore, ASRock Restart to UEFI technology allows users to easily enter the UEFI setup utility automatically when turning on the PC next time. It is designed f
