I think the OP has probably left. He's got his CPU upgrade. It worked as well as he'd hoped, which is fantastic. His ram is good enough to get by with. If he wants more he knows 3200mhz is a safe bet and 3600 is not guaranteed and possibly not even worth the trouble.
As for the arguments, it's silly. For Ryzen AM4 boards CPU memory controllers are more often than not the deciding factors for memory frequency.
Any Google search for "best Ryzen 5000 series memory" reveals threads, articles and videos that state the same thing. 3200mhz is a solid safe choice, 3600mhz is the next step for the enthusiast to try, but it's not guaranteed. Some people "gasp" may even go beyond 3600mhz. I know, it's like the world is literally falling apart.
It's all been stated multiple times by just about everyone involved in this thread. The arguments are really arguments about the same thing with differing positions..
Blatant personal attacks for no real reason. Staunch false information that B350 boards can't and won't run anything over 3200mhz... It's incredible that one person involved is so aggressively wrong. Holding onto a patently false position, with absolutely no advice for the OP, just proving the lack of knowledge about old AM4 motherboards paired with the most modern AM4 cpu's.
Oddly enough that same disruptive poster is also incredibly knowledgeable, helpful and patient just about any other thread I've seen him involved in.
I'll be leaving this thread, wishing the OP continued luck with his upgraded build.
