Last month I tried to upgrade my Mom’s 2012 MacBook Pro with this RAM - Crucial 8GB Kit (4GBx2) DDR3/DDR3L 1600 MT/s (PC3-12800) SODIMM 204-Pin - CT2K4G3S160BM. It would run for a bit but then crash and never figured out why. The attached picture is the specs for her Mac. I’ve searched all over google for an answer and can’t figure out why it failed.
Replace the old RAM first and get the machine running. Next replace just one stick of the new RAM and see if it works. Now try the new stick in the other slot. This checks both the RAM and the slot. Repeat with the second stick. Are you getting any beep tones? UPDATE RAM Type:PC3-12800 DDR3LMin. RAM Speed:1600 MHz Details:Supports 1600 MHz PC3-12800 DDR3L SDRAM SO-DIMMs (204-pin).

That RAM should work fine. There must be something wrong with it.
Try reseating the ram. This means taking it out and putting it back in. I would also take an air duster to the slots to remove any dust. If it still crashes, then your ram sticks may be faulty. If they are still under warranty, you can return the faulty ram and you should get a replacement.
