So the B450M-HDV R4.0 says Max. capacity of system memory: 64GB* but every website says 32GB can anyone give me any insight on this? I'm not that technical

Old docs had it at 32GB max, because they were written before 32GB DDR4 DIMMs were a thing. AsRock's own support page for Fatal1ty X470 Gaming-ITX/ac STILL SAYS it only supports 32GB max, but that is 100% wrong, because I ran 64GB (two 32GB DIMMs) just fine.
