[NAME] I think the increase in the amount of RAM will, in most cases, override the loss in speed. If you assume your applications and data are limited by the amount of RAM then there will be swapping to your HDD or SSD, both of which are going to be much slower and take more time than the loss of RAM speed. 
My new XPS 8950 i9 with 2x16GB RAM is used for heavy audio recording and Vegas Pro19 and DaVinci Resolve 18 for video editing. I am also using an RTX 3060 Ti for the GPU. I would like to add another 32GB (2×16GB), but understand the RAM speed will drop. Would the increased RAM override the loss in speed in most cases? Or typically with the software mentioned above?
