Does the Pro Tower 400 G9 PCI take DDR4 or DDR5 RAM? I can't find a definitive answer in any documentation. I see both mentioned, and some sources suggest that it depends on the processor. I'm looking at a i7-13700, which seems to take DDR5-5600, whereas some other processors seem to be associated with DDR4. I don't want to have to buy the machine and take it apart just to see what type of memory it uses. I have to look at upgrades and pricing first, as apparently pre-built configurations only go up to 32GB, and I want 64GB.
