    So I know it supports 3200MHz

    But when I look up DDR4 on Wiki, it has 3 options listed

    When I look for RAM, there are 2 kits by Crucial. One is CL22 and one is CL16 (Ballistix)

    Is it worth paying extra for the CL16 kit? Will it even run with those timings?

    What if I find some with even lower CL than 16, is it worth paying a little more if I get a good price?

    CL16 is certainly better than CL20, CL22 or even CL24.

    Tighter timings = better overall performance and responsiveness from the APU.

    The system should easily run at CL16... timings are not dependent on your computer to support it... RAM speed is.

    If RAM is operating at 3200MhZ by default (And we know the APU supports it) and you found this RAM with CL16 timings, then the timings should function out of the box.

    Zen 2 is a bit less dependent on RAM speed and timings than Zen 1 and +, however, lower timings still make an impact on CPU and iGP performance.

    I had bought 2 sets of 16gb(8+8) RAMs of 2 different clock speeds @ 2666mhz and 3200mhz for my acquisition, both from Klevv.
    One which now is in hand, with 4600H+gtx1650 combo.
    Another which I'm awaiting to get with 4800H+1660ti combo.

    This!!! Is why we see the TongFang/Elutroniks RP15/17 variants offered in other parts of the world, doesn't necessarily cones with 3200mhz RAMs.

    Not unless the BIOS has XMP support, and the board can handle those timings.

    I found out my laptop (Dell G5 SE) doesn't have XMP support :(

    So which is the best RAM for me?

    Kingston HyperX has ddr4-3200 cl20 jedec timings.

    Isn't XMP only to overclock RAM speed (not RAM timings)?

    Why don't OEM's integrate XMP support into AMD laptop BIOS?
    Its not that difficult.

    JEDEC timings for 3200MHz are CL20/CL22/CL24 as per OP's image. Anything tighter than that is XMP.
