I'm curious about which AM4 CPUs are most likely to run 4000MHz RAM reliably. I've heard that the stable limit is typically around 3800MHz, and only a few lucky users manage to hit 4000MHz. Does the 5800X3D have better chances for stability at this speed compared to the 5950X? Also, I find it odd that my B450 motherboard is said to support up to 4100MHz, yet it seems no CPU can achieve stability at that speed.

I saw a comparison where a 5600X with 3200MHz CL16 performed similarly to a 5700G with 3800MHz CL14. So while the 5xxxG series can reach higher speeds, it doesn't always translate into better gaming performances.
It really comes down to the silicon lottery and how well your CPU’s memory controller plays with the RAM. The newer 5000 series should theoretically provide better stability at higher speeds compared to older models. Just keep in mind that support numbers from motherboards can be misleading; actual performance can vary.
Generally, the Ryzen 5xxxG series CPUs have better memory controllers and tend to handle higher speeds more reliably. But they might not perform as well overall—that’s something to consider! Are you just chasing a high RAM speed for bragging rights, or are you trying to enhance performance in specific applications?
I’ve been able to run 3600MHz CL16 on my 5800X, and while some people claim to hit 4000MHz, it can be pretty tricky with stability. For gaming, the difference isn’t huge—especially with X3D models where speed boosts aren’t as noticeable compared to standard Ryzen chips. I’d suggest aiming for stable 3600MHz CL16 instead.
Absolutely, it’s more about the CPU and RAM compatibility! The motherboard just helps connect everything.
