    Hi KeeganJ,


    Thank you for submitting you question in Intel Community,

    I'm Adzim, application engineer will assist you in this thread.


    You have right understanding on IO banks usage.

    I also would like to suggest to use "Option One" because you can use termination on LVDS IO bank.

    The VCCIO for DDR3 protocol must be driven at 1.5V.

    The option below is correct.

    - Option One: 2A (data), 2J (addr/command), 2K (data)


    Regards,

    Adzim
