honestly that's something i'm going to have to leave for someone else
to investigate / answer, i've been non-stop for about 6 days on the
PCB layout, it's one of the trickiest i've ever done as the 4 DDR3x16
RAM ICs are all on the TOP layer, leaving an absolutely ridiculously
small amount of space left for routing, and i'm having to make some
rather creative decisions on where to place some of the discrete
it's extremely taxing, very intensive, so i'm trusting that other
people will answer software-related questions.
