Absolutely no need to get that expensive RAM, any issues where you actually would need that samsung b-die are gen 1 CPUs and x370/b350/a320. And with the newest and/or the best bios for a specific RAM you will probably see no problem even with the old stuff which again is irrelevant in your case anyway.
You're gonna be able to run that corsair RAM at 3000MHz and probably even at 3200MHz with just the RAM voltage at 1.36-1.39v.
Unless you actually need the integrated wireless it's not a stepdown, the b450 Tomahawk is the best next thing you can get after the carbon.
