    The motherboard I have is a Gigabyte Technology Co. Ltd. B150M-DS3H-CF (U3E1)

    I already had two 8GB sticks, specifically GeIL EVO POTENZA 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) Intel Z170 & Intel X99 Desktop Memory Model GPR416GB2133C15DC

    Those were being recognized just fine and working without a problem. I ordered another pair of 8GB sticks (same exact model), installed them, but my computer is only recognizing the original two. Where do I go from here?

    Try swapping out the old RAM and inserting the new in the same slots and see what happens.

    And be sure to take the necessary ESD prevention precautions. That is, unplug the computer from the wall and touch bare metal of the case interior BEFORE reaching inside the case or touching the RAM. This is to discharge any destructive static in your body. And never touch the RAM's electrical contacts.

    Aha! That did it. 32GB up and running. Thank you very much.

    Not sure why that did it, but glad it worked. Thanks for posting your followup.
