Update 19/06/2015
now I am disappointed by the Board. Under Windows 8.1 makes SATA and USB 3 problems. 2 plates not converge on AMD SATA Controller ---> after booting System Freeze, on ASMedia controller there are no problems. USB 3 runs on Etron controller stable after I have the latest drivers installed directly from the manufacturer's site. In this Asrock there not to download!
