I am looking to buy the Asrock Z170 Extreme 6+ motherboard and I don't know if my RAM choice is compatible with the board (it is not listed on the Asrock website and the speed of the ram is 3000mhz CL15). The RAM in question is Corsair Vengeance LPX 2x8gb 3000 mhz CL15 (CMK16GX4M2B3000C15). The Asrock board seems to support 2933mhz and higher RAM clocks but not 3000mhz. The RAM would downclock itself to 2933mhz (with XMP enabled) or will it run at 3000mhz?
