The memory controllers on Zen 2 and 3 CPUs are generally considered superior to those in Zen+ and Zen.

They perform significantly better now. Earlier resolutions capped around 2666-3000, but higher ones like 3600 reached close to that. Most stayed near 3200. I'm using a 5800x3D at 3600MHz and my 3800x was stuck at 3200MHz.
Move smoothly from your current 2400 up to the rated 3000 using a 5600 CPU.
I've found the most stable performance with my Zen+ 2700X at around 3400 C18-18-18 on a 16GBx2 3600 C18 board running at 1.4 volts. A slight increase in SOC voltage lets Zen and Zen+ operate smoothly at 3200, while keeping it below 1.15 is ideal. I usually stay near 1.05, but 1.2 volts can be harmful over time. Not every board tracks SOC perfectly, so staying safe is wise. My experience with Zen2 or Zen3 is limited now, but things are about to change, so I'll share more from a casual perspective soon.
Intel developed their memory controllers from foundational technologies, building on established semiconductor principles rather than inventing them from scratch.
I’m confident it works for AM4, my 5600-based systems function without issues.
