Hi Everyone, I'm just about to upgrade the ram on my 3x MacPro 4.1>5.1's, all 12-core 3.46. 2 of the machines are running dual 1080ti's for redshift rendering and could do with a bit more ram. They all currently have 32GB (8x 4gb) and I'm about to purchase an extra 4x 16gb for each machine which will leave me with the potential to upgrade to more if needed in the future. With 4x 16gb installed, will I be ok filling the remaining empty slots with 4x 4gb or will there be any issues? Also if I do go this route, what would be the best slot configuration for a mix of 4x 16gb & 4x 4gb? Any help greatly appreciated!
