V3.0.1 RAM Question

I am using 100% AHQ to denoise/deblock an 8k video. I am also using Chronos Fast to add more frames.

I have 32 GB of RAM, and this workflow easily drains that down to (at times) about 500 MB of RAM available. It seems clear that I need more RAM, but will 64 GB be enough?

I’m hoping there’s someone out there with some experience with similar demands to help answer this question. Thanks!
