Review on 🚀 A-Tech 64GB (4x16GB) DDR4 2666MHz RAM Upgrade Kit for Apple iMac 2019 & 2020 27 inch Retina 5K: Enhanced Memory Performance! by Joshua Romero

I have a brand new iMac 27" Retina 5K 2020 and I bought this 128GB A-Tech RAM as an upgrade to my system's 32GB, but this A-Tech memory has the performance of my system in none Wisely improved I have worked with Apple to make sure nothing else happens and they have assured me that my system is optimal so I should see a performance increase since I upgraded A-Tech RAM from 32GB to 128GB , I'm having more issues, so I went back to my default 32GB and stopped buffering.
