g.skill f4-3200c14-16gtz

Hi, my current S4Mini build has a ASUS X-470I motherboard with Ryzen 7 2700X CPU and 32GB G.Skill F4-3200C14-16GTZ RAM Unfortunately 32GB is not cutting it for me even overclocked to 3466 MHz. So I was wondering if anyone successfully installed 64GB or even 128GB? From what I'm aware of the CPU...
