I currently have 2x8 GB of RAM installed in my PC. Motherboard ROG STRIX B350-F. My question is what is the difference between CMK16GX4M2D3200C16 (Which is what is installed in my PC) and CMK16GX4M2B3200C16. I am thinking of installing more memory. I want to know if they are compatible with each other.
