Is the RAM on the QVL list provided by the motherboard manufacturer?  I had this issue when I got overeager and bought a DDR-6000 CL30 G.SKILL kit only to realize my motherboard's QVL only listed the CL36 flavor of the kit.  I ended up returning the kit and getting the verified kit and have had no issues since.  I felt a bit foolish, but G.SKILL's website had listed my motherboard as good, so I thought I was in the clear.

So, generally QVL lists are created when the motherboard is released, and a lot of the time they're never updated. It sucks because RAM vendors often EOL the QVL'd products in favor of newer ones.  


Generally, if I'm looking at some RAM and it's not QVL'd by the manufacturer for their board, but something else very similar is, I call it good. Never had a problem so far. "Board says it supports Corsair Vengeance DDR4-3600 C16 model 2344423GQ354ATT and I've got Corsair Vengeance DDR4-3600 C16 model 234B77D398ALL? It's probably good.".  


Hell, if it supports "Corsair Vengeance DD4-3600 C16" and I've got Corsair Vengeance DDR4-3600 C18, I'm sure it's probably good.
