It can be upgraded very easily. Go to the apple and the memory tab where you'll find a link to instructions on upgrading memory.
(I didn't notice this comment was so old. You must have an answer by now.)
My question as well
[doublepost=1535526219][/doublepost]
How did it work out?
Im getting a New 2017 27 inch i7 sendt to me as a replacement for a broken earlier model imac. In my old one I had 16+16 ddr3 ram which worked fine ( 16 apple ram 16 3rd party ), so Im assuming since im getting 16 ram from apple its 2x8 and 2 slots are free.
Any1 know for sure ? Hope its not 4x4 .. ordering 16 ram now would otherwise be a waste.
I know this ram will work
Crucial DDR4 2400Mhz
PC4-19200 - Unbuffered 260pin
thx
Thomas

Will These RAM Cards work for my iMac 2017?

Yes, I highly recommend it for the 2017 iMac. I've been using 32Gb of that exact RAM in my own 2017 iMac for over two years now.
Get the 2400 MT/s part though. Your link is to the 2666MT/s. It will likely work with no problems in the 2017 iMac but throttled.
This is the one you want:

After reading this thread thoroughly I plumped for these Crucial bad boys Crucial CT2K16G4S24AM 32 GB Kit... https://www.amazon.co.uk/dp/B072K5NPRM?ref=ppx_pop_mob_ap_share and installed them into the 2017 3.5ghz iMac I recently purchased (heavily discounted as it’s now an outgoing model). Works perfectly in the thing is now like a F1 car! Really pleased and thankful for this thread.

32GB vs 16GB sticks?
Will 32GB 2666MHz memory stick perform roughly as good as 2x16GB 2400 MHz, if mixed with pre-installed 2x4GB 2400MHz sticks?
I'm choosing RAM to upgrade iMac 2017 27" i5 3.8GHz. Similarly to @logas69 in a related thread, I'm considering to buy one 32GB stick now, and add one or two more when I can afford it; ideally using it alongside pre-installed 8GB.
I've seen reports (1, 2) that 2666MHz can work with i7-powered iMac--but didn't find anyone tried it with 3.8GHz i5 which I have.
Similarly, the above reports quote that 32GB sticks are supported with i7, but it's unclear whether they will work with 3.8GHz i5.
The 2400-2666 mix is believed to work correctly (assuming BootROM 172.0.0.0 and Mojave 10.14.5), but I haven't seen any reports proving it nor comparing performance between "mixed" and "same-frequency" setups.
As for double vs single-channel, I've seen some non-Mac benchmarks (see Benchmarks section) which suggest the difference in neglible in real-life scenarios, but again I didn't find reports specifically for Mac.
For reference, these are different-capacity mix, double+single-stick benchmarks (1, 2) suggesting adding a single stick won't degrade performance.
