Samsung's 32GB DDR4 ECC (M393A4K40BB0-CPB, NOT LRDIMM) module is finally trickling into the market, and the prices I've seen are actually quite reasonable. Will these work on the X99e-itx/ac? The maximum system memory for the board is listed at 32GB - is this because the BIOS specifically caps support for a maximum of 16GB per DIMM slot or because 16GB modules were the largest in the market at the time the specifications were written? That is:

- Will the board POST if I install one 32GB module? Will the board detect 32GB of RAM?

- Is there a possibility that I can have 64GB of ram using two of the aforementioned modules, despite the listed max RAM on the specifications page?

To give a little context, the Memory QVL list for X99e-itx/ac is woefully incomplete (no 16GB modules are even listed despite some of Samsung's offerings being listed on other ASRock X99 board's list). I do know (and have tested) a 16GB Micron module is working fine on my board, so this leads me to believe that many modules out there have not had the opportunity to be tested and may in fact work just fine.
