回答“Does iMac accept 64GB of RAM?”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.
