Memory upgrade for Late 2013 iMac 27" - add 16GB to 24GB?

[bugzy]

So standard for the late 2013 iMac 27" is 8GB. If I purchase additional (2x8GB - 16) from Crucial, can I add to the 8GB totaling 24GB, or would I need to remove the original 8GB and toss them to storage.

Thanks for the help. First Mac, even though I work in IT.

Should be fine. I did this with my 2012 iMac and worked great.

Where'd you see the most noticable improvements after going from 8 to 24Gb? Apps opening and responsiveness? Video playback? Thanks!
