    Hi sorry to hear.
    I do not have a qcode table for my Zenith, but on my RVE10´s q-code table it says code 55 is "memory not installed"
    I might be wrong cause it is a different board, kinda hope Asus will make one.

    Have you tried all memory sticks one and one in the A1 slot?

    Some other things to check.
    The 3 screws on the CPU load plate needs to be properly tightened
    all the way until they stop. Do not over tighten them thou.
    Both 8 pin CPU plugs and the 24pin should be used on this board,
    thou I think it should start anyway with one 8 pin CPU plug.

    Also you can try clearing the CMOS.

    Hold the clear cmos button while the system is powered off for about 3 seconds.
