What is the best DIMM upgrade for multiple video ...

What is the best DIMM upgrade for multiple video animation programs? Right now I have 4 slots with 8GB, iMac 5k, 27-inch, 2017, 4.2 GHZ core i7 Thanks!
Asked by: Denise
Hi there, I'm rocking 72GB of RAM on my 2019 i9 iMac. I purchased this OWC 64GB DDR4 2666 MHz SO-DIMM Memory Upgrade (2 x 32GB) in 2019 for the two empty slots and left the 8GB that came with my system in it. I'm a multimedia artist, which means that I'm mostly editing 4k videos in Premiere Pro and animating in After Effects and Cinema 4D. I've been using my iMac for over a year and I've not encountered any issues with performance. Even while running all these softwares simultaneously and much more, my system NEVER lags and everything still performs as it should. So you could choose to go all out and swap out your original 8GB too in order to rock 128GB or go my way with 72GB. Either way, I think you'll be fine. I hope this helps.
