Chosen Solution

I have an iMac Pro 2017 8 core 3,2 with 32 gig RAM (EMC 3144). Can I upgrade the RAM on this model? there is no reference to EMC 3144 on the ifixit site

We don’t have a guide to upgrade the RAM for this system. Apple made the design much harder than the regular 27” iMac’s which have a RAM access door. Here the system needs a complete teardown lifting the logic board fully out to gain access to the four SO-DIMM slots. Unless you’ve done a bit of work on the newer 2013 ‘Thin Series’ onwards iMac’s so you are comfortable in taking the display off and have taken out the logic boards I would recommend you find someone who has, as this is an expensive system to get repaired if you make any errors. OK I’m going for it! First you need special PC4-21300 32 GB ECC Registered RAM iMac Pro Memory Maxxer RAM Upgrade Kit Follow this guide to take the display off iMac Intel 27" Retina 5K Display Display Replacement the cable connections are slightly different than what this guide shows.
