Hello! Could you please help selecting compatible memory upgrade? My machine is 27`2017 iMac Retina 5K 3.5GHz Core i5 processor with 8GB 2400MHz DDR4 The selection tool does not list the exact model, showing only two options: Apple iMac (Retina 5K, 27-inch 3.4GHz Intel Core i5, 2017) iMac18,3 or Apple iMac (Retina 5K, 27-inch, 2017) iMac18,3
Thanks for contacting us today. I pulled up your system on my end and it looks like we do list the upgrades on the iMac (Retina 5K, 27-inch, 2017) iMac18,3 listing. The upgrades on that link are compatible with the Imac 3.5GHz Quad-Core Intel Core i5 model. Please let us know if you have any other questions or concerns about upgrading.
