Ryzen Memory Compatibility

Just wondering how important is it for memory to be on the ryzen memory compatibility list. I'm helping a friend build a PC. He's going 5900x, and does rendering. I'm thinking of getting memory that has a 4000 speed, but that doesn't seem all that common to find. I found these, https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820374021?&quicklink=true, but they're not on the compatibility list.

Things on the compatibility list are tested by the manufacturer to work, things not on the list haven't been tested but will still probably work. Having RAM that is that fast though might be too much for the memory controller, but how fast the memory controller can work is partially upto chance. It will probably work, but it is not guaranteed.

I wondered if that would be the case. I was only thinking that high to bring it in 1:1:1 with the f clock assuming AMD can get the f clock up to 2000. I'll probably just have him settle for 3800 if that's the case. He's coming from a 2014 Macbook, so he's not going to notice that type of a difference.
