This iMac is really a laptop hiding inside and so has a mobile i9 CPU with only two memory channels (not the 4 in a “real” desktop i9). It has two DIMM slots on each memory channel. You have to keep both those channels populated with identical DIMMs configurations. So could, as suggested above, keep your 2x4GB DIMMs and add 2x8GB DIMMs, but if me I would probably buy all new 4x8GB DIMMs and get 64GB. That iMac actually supports up to 128GB if you want to go crazy. Buy from OWC or similar high quality seller.

Lots of memory always helps, modern Pro Tools systems requirements is 16GB, it’s possible but a challenge to run on less, being able to throw lots of stuff at disk cache is great, even a web browser (cough Chrome) nowadays can easily burn 8GB.

Darryl, I couldn't agree more. 32GB of ram would be good, 64 would be even better. You mention 2 memory channels vs 4 in the latest 2019 iMac i9. Is there a noticeable difference in performance? Also, I currently run the latest Mac mini 2018 i7 6 Core (32gb ram). It's pretty much a little beast and I'm able to run large sessions with VI's, plugins, tracks, etc, including Vienna Ensemble Pro (18 channels) but the Mac mini temperature does fluctuate between 85 degrees Celsius and 98... sometimes even hitting 100. I'm running this setup roughly 10 hours a day. Would I be better off with the iMac i9 8 core? The overall specs seem to be good, almost doubling what I can get now, according to what I've read. Thanks.

Btw, I don't mean to take away from the original post. Error -6101 is a huge concern for me too.
