I have bought a 4 sticks kit of 32 GB ram sticks and I am running them at 4000 mghz/MT and 2000 fclk with cas latency of 18 but I am not certain where I can surely confirm I am running 1:1. I am really concerned because it is really rare to get this with 4 sticks on Am4 CPUs. I am also have a Ryzen 7 5700X and MSI mag tomahawk b550.
