Hi, am doing a build and I saw the mobo specs say for the RAM .... 2400 MHz, 2133 MHz, 2666 MHz, 2800 MHz (O.C.), 3000 MHz (O.C.), 3200 MHz (O.C.) Does this mean I can only buy upto 2666 MHz? Or does it mean I can buy 3200 MHz but only if my CPU is over clocked? Sorry but I don't get how to interpret this The mobo is an ASUS STRIX B450-F.
