Will two Samsung DDR4 2666 8GB Ram SO-DIMM work with a 2013 Imac Core i5 27"

Hi,

I currently have 16gb of ram in my 2013 iMac 27" Core i5 and my computer is running fine but I also have two Samsung DDR4 2666 8GB Ram SO-DIMM that aren't being used on another laptop, will I be able to add those two DDR4 to my Imac and upgrade the ram to 32gb of ram or are they not compatible?

Any assistance would be greatly appreciated!

Thank you,

Kirk
