I know that Ryzen 5 3500U supports 2400mhz memory but my laptop's default memory frequency is 2666mhz. When I visit task manager, it says its only using 2400mhz. I'm planning on adding another memory since there are two slots. My question is should I get a 2666mhz ram or 2400mhz? I don't want to fry my laptop because of different frequencies, or because of high frequencies. Which one would be safer? Any help is appreciated!
