"Guys! Save your money and just purchase the 32GB RAM.

I purchased a brand new iMac 5K about a month ago from Apple and went ahead and purchased 64GB RAM upgrade from OWC and have been getting many kernel panics when rendering. I took my computer in to the genius bar and concluded it was a RAM problem. Contacted OWC for a replacement. I had also returned the iMac just because I was within the return policy (they recommended me). I got all brand new items again and gave it a shot and same thing. Was getting a lot of kernel panics during rendering in either FCPX and DaVinci Resolve. Again, I contacted OWC and they gave few troubleshooting steps and nothing worked. I ended up going back with the stock 8GB RAM it initially came with and problem solve. This has been a complete waste of time and money. I strongly don't recommend buying 64GB RAM.

Save your time and Money."

"The first iMac 5K supports 32 GB max. The iMac 5K late 2015 supports up to 64 GB .

Would you need that much RAM? Most users not. Music & video editors do, graphics design professionals do. When I make a 400+ pages book in InDesign with over 900 images 16 GB of RAM just isn't enough. It's impossible. I tried, either the OS or InDesign crashes. 32 GB is great. Also with 32 GB of RAM most of the time there is no need for memory compression or need to swap which improves performance greatly, especially on older systems.

I use a late 2009 iMac 27"" i7 with 32 GB of RAM which I will retire in the next year."
