    Strix Z490 E A2 code on first boot

    Memory 2x8 corsair
    cmw16gx4m2c3200c16

    Core i7 10700k

    Strix Z490 E Bios 707

    M.2 980 pro 500gb. Yes I know it's a pcie 4.0 and motherboard does not support 4.0 so it will run at 3.0

    At first boot getting A2 error code and green boot light is on.

    Tried with one memory stick and still get A2

    You need to be more descriptive of the problem, as well as your configuration if you expect to get some help.

    Take a look at this: https://www.reddit.com/r/buildapc/co...490e_a2_error/
    Also post BIOS photo with your boot device(s).

    After some research found the easy solution. Plugged keyboard in back of motherboard and not front case usb, which received the magical Asus Bios screen.

    Thanks
