I wanna buy an MSI B450 Tomahawk with Corsair Vengeance LPX 2x8GB DDR4 3000MHz CMK16GX4M2B3000C15W kit (The CPU will be a R5 2600). On the QVL it says its supported at 2933MHz. Is there any noticable difference compared to 3000MHz? If yes is it possible that i can manually set the speed and timings to the one offered by the manufacturer?
