    I've been looking for recommendations for a while now and it's downright confusing. I need dual channel.

    We need more information from you. What mobo/chipset do you have. procesor, are you overclocking, and what's your budget.

    Whatever uses Samsung B-die modules at whatever speed you wish to run.

    Can usually be found by looking at the marketed CAS rating. For example a 3200mhz kit at CL14 should be Samsung B-die if I'm not mistaken.

    Asus ROG Maximus X Hero, Z370 Chipset.
    Delidded i7 8700k @ 4.7.

    My confusion stems from what I've read that CAS latency and Speed isn't the entire story - Speed can cancel out longer CAS timings. So there should be a sweet spot of Mhz and CS. Then there's "Dual Ranked vs Single Ranked" memory.

    I'd like to run the memory at stock except for the XMP.

    Budget for four sticks, $600.

    Most if not all of your bleeding edge Mhz DDR4 kits use Samsung B-die modules. So you can pay up for a crazy 4600mhz XMP bin or you can get a cheaper known b-die model say at 3200mhz, then overclock it yourself to theoretically the same speeds and save $$.

    At the end of the day, no bleeding edge memory speed can be guaranteed as you are at the mercy of the quality of your particular 8700k's integrated memory controller.

    I'm not sure if there is a huge variance in B-die overclocking so that may be worth investigating.

    For example here is 3200mhz CL14-14-14-31 kit that guarantees Samsung B-die modules being used. Link

    8g b die will be single rank but 4 sticks of single should perform the same as two 16g dual rank sticks
    4 sticks may even oc a little better in that mb

    2x16g 3200c14 is the best i found at newegg for under $600
    a more expensive option that may be a little faster
    4x8g 3600c16 $664
    there final latency will be similar but the later will have more bandwidth

    one other option might be 4x8g 3866c18 $620
    its latency may be a little worse but the higher bandwidth will balance that out in some applications but not others
    and same for 2x16g 3733c17 $637
