Not my experience at all. I bought a Ryzen 3700X with 4x 16GB 2666MT/s Kingston ECC. Memory chips turned out to be Micron revision E, same as used in many popular Gaming XMP sticks.

I could run these at 3333MT/s and lower CL from 19 to 14. Thus, raw latency going from 19*2000/2666=14.2ns to 8.4ns. After recently buying a used Ryzen 5950X I can now push the memory to 3600CL14, or 7.77ns. At this point I'm at the limit of what I can cool without starting to hear my PC.

And at this point I'm running my memory at the same speed as G.Skill Ripjaws V Black, which is the fastest gaming memory I could find available here, but the G.Skill is twice the cost. Though, I see that it's also available as 4600CL19, and I actually never tried decoupling the memory clock from the fabric clock after upgrading my CPU since I couldn't push 4 sticks fast enough on my 3700x that I'd make up for the decoupling. I should probably try it out. Suspect I won't hit 4600MT/s though, but I don't think I would be able to run the G.Skill att 4600CL19 with 4 sticks either.
