im building pc w/a MSI MPG X570 mobo tha t can accept ram up to ddr 4400, but since i have 900 to spend right now i can afford a 3400g apu (the accepted ram default is 2966mhz recomended) but i want to buy the ddr 4400 that the mobo accepts now within budget so dont have to spend on the ddr4 2966 now an sell later on. the question is can i buy the ddr 4400 now an everything would be compatible?
