Board Software
The software package provided with the ASRock X99E-ITX/ac is pretty standard fare, which isn't to say it is not enough; there is a huge host of software available, most of which are rolled into ASRock's A-Tuning utility. AS the central repository for the majority of the ASRock X99E-ITX/ac's software tools, this simple interface can launch many different applications, including X-Fast Ram and Fan-Tastic Tuning.
When you need more, or are looking for updates, you can take a trip over to the ASRock website, or you can open up their App Shop to find all the same things there, including, perhaps, a game or two! There is also a utility that will force the board to reboot for a direct boot into the BIOS, and there is the usual X-Fast LAN utility that will allow you to analyze and optimize your network traffic.
