    Hello I´ve been also getting a OEM post memory initialization code, specifically a Q code 40 on my System.

    My rig is:
    Maximus V Formula
    Intel Corei7 3770k OC to 4.4
    12GB of Kingstone HyperX Genesis !600mhh RAM
    GEForce GTX770-SC GPU
    Kingston SSD-Now 128GB with system on it

    The problem in my case is this:
    I am getting QCode 40 every now and then when I turn on my PC.

    I had some problems with the MOBO, at first I had 16GB RAM (Kingston HyperX Genesis 1600mhz) but when I was playing high end games the machine just rebooted or freezed and then at reboot the QCode reader showed me a 55 QCode (no memory installed) I cheked my 4 dimms, slot by slot, dimm by dimm and 3 out of 4 passed the test, one did not which is very weird, but since then I´ve worked with only 12GB and it´s been working fine, no 55 QCode, also reinstalled windows from 0 because sometimes it also gave me QCode AE (Boot legacy event) and since reinstall no AE code has been given, but this QCode 40 worries me, the PC turns on, works fine, but insted of AO QCode (Normal Functioning) it shows QCode 40 on the MOBO code display, please help me what can I do, is this a problem with the MOBO RAM Slots? should I change my RAM?

    I´ve tried with the MemOK! Button and apparently it works, but then again and again the Q Code 40 appears again.
