Greetings All. Just purchased a 2019 i9 iMac with the Vega 48 video card. Will upgrade the ram from 8gb to 64GB or maybe more. I'll use the machine for video work, lots of image editing in Lightroom, and architectural renderings using lumion which I will run from windows in boot camp. I'm leaning towards buying 2x32gb for 64gb total. This will leave 2 dims open so I can add 64 more in the future (total 128gb). I'd probably also keep the existing 4gbs in their slots which would give me 72gb total ram. Here are my questions:
1. Has anybody done this?
2. Are there any potential pitfalls mixing 32gb with 8gb? I assume no given that others have made this work with 16gb and the 8gbs.
2. At 64gb ram are there any performance reasons to choose 4x16gb over 2x32gb?
3. The machine has eight cores. Somewhere I read that a good rule of thumb for video editing is 4gb of ram per core and that anything more provides very little gain in performance. Is this true? If this is the case then even 32gb ram would be appropriate and 128gb would just be ridiculous overkill???
Thanks much for any and all feedback!
