The 2017 iMac with retina display accepts a total of 64gig. Lucky you. If you can afford it, go for the max. And by the way, save yourself big money and install non apple memory. I have been running my apple iMac 27" with third party32 gig memory without any problem. You choose, good luck and enjoy.

I expect to pick up my new iMac today or tomorrow. It comes with 8 gb of RAM, which I will upgrade to 40 gb (by adding 32 gb). I would like opinions on the best companies (Crucial, Adamanta, Corsair, etc. ) from those who have actual experience.
Thanks.
