I would like to be able to distinguish RAM that failed validation testing and RAM that has not been tested in this article: What DRAM/memory is supported by Framework Laptop 13 (AMD Ryzen™ 7040 Series)?
They probably didn’t find any RAM that failed validation, or they’d have documented it. Usually any RAM that meets the required JEDEC standard works fine and incompatibilities are very rare. Framework would probably have to test a lot of weird and exotic modules until they find one that doesn’t work.
That’s very nice of you to speculate what Framework has and has not tested and maybe that’s good enough for you. I would prefer to know.
