By all accounts, Samsung B-die is the one to get with Ryzen. My understanding is that Samsung B-die = Samsung B-die, regardless of whether the marketing says “For AMD” or not. Overclockers seem not to have seen any difference between them anyways. And 16GB 3200 @ CL14 = Samsung B-die.
One advantage of sticking to QVL is it makes it easier to deal with support/RMA. I had issues with my C7H and Asus support asked for my memory model. They mentioned it’s not on the QVL, but when I said I had done extensive memory tests with no errors, they let it go and said then it’s likely the board is faulty. YMMV.
