My laptop is: Acer Aspire 3 A315-23G-R63B

I wanna upgrade ram, 4GB to 8GB.  My old ram is 3200MHz (https://eu.mouser.com/datasheet/2/671/atf4c512x64hz-1284544.pdf), but 2400MHz usable, because Ryzen 3250U limited to 2400Mhz.
If I wanna buy RAM, what clock time with? 2400MHz or 3200MHz?

    Yes both will run only at double data rate (DDR) the base 1200MHz frequency or 2400MHz maximum. Shop price. Don't pay extra for higher frequency RAM than 2400MHz. Jack E/NJ

    Whichever is cheapest because both will only run at double the 1200MHz speeds of the bus. Jack E/NJ

    So it matter which one I buy.

    Crucial 8GB DDR4-3200 SODIMM CT8G4SFRA32A or Crucial 8GB DDR4-2400 SODIMM CT8G4SFS824A.

    Because the processor will run at 2400Mhz.
    if I understand correctly
