The LS1046ARDB's document said it supports 8GB DDR4, does it support 16GB? I'm thinking about a product with LS1046A, it need support 8GB or 16GB DDR4, with/without ECC. Does it possible? Can you just put a DDR4 slot as LS1046ARDB? I found it connects all 4 chip selects and address lines to the slot already.
