    Default Max memory on C2750D4I

    Hello, as stated on Asrock's web and on Intel's web for Atom C2750 they both should support 64GB of RAM.
    But when I put Crucial 16GB DDR3 1600MHz 1.35V LRDIMM ECC module (1 or 2) motherboard doesnt boot.
    With some 4GB nonECC kingston boots just fine.

    What modules I should use to get full 64GB of RAM into this board?

    The board only take unbuffered DDR3 DIMMs (UDIMMs), not LRDIMMs or RDIMMs.
    UDIMMs may not use more than 16 chips, or 18 with ECC.
    To make UDIMMs or SO-DIMMs with 16 Gigabyte, it requires DRAM-chips with a capacity of 8 Gigabit per chip.

    Those have just been introduced by the company Intelligent Memory, which also offers complete 16GB DIMM modules, optionally with ECC. Click here: DRAM Memory Modules | 16 Gigabyte DDR3 unbuffered DIMMs | Intelligent Memory
    ASRock Taiwan is currently testing these. A BIOS update from Intel is required. I just heard today that ASRock has the boards running with total 64 Gigabyte already.
    Also the Supermicro board A1SAi-2750F should work with these, but in SO-DIMM form-factor, which are also being offered.
