RAM memory, What does it mean limited validation?

Hello,
I don’t understand what limited validation means
In the validated module list for the RAM, does it mean that they won’t work well? Sorry if I’m not clear enough English is not my first language

I am not exactly sure what the Limited validation means. I think it means that based on user feedback, they appear to work OK. But have not been fully checked by FW.
For example, I have 2x 32GB Kingston Fury KF556S40IBK2-32 in my FW16 at it works fine for me.

Ok thanks for your answer!
