    downloaded and checked SN. this is not 820-2337.
    it's 2012 model .
    2337 is 2010 model

    can you double check and upload the correct 820-2337?

    Here is ROM for Macpro5.1 but 2010 from 820-2337-A board, I tried it on Macpro4.1 and it's works great. High Sierra also works fine with it.
    Please note - Serial Number replaced with XXXXX, maybe you need to edit it.

    @ThienBui
    Is the bios dump from 2012 MacPro5.1 will work on MacPro 5.1 2010?
    Clean ME for that dump?
    Motherboard (backplane) are the same so I assume it should?!

    @hernan tangoa f. If MacPro have fans running like crazy, it means the CPU tray is using a different SMC version than the system tray (backplane)
    Like if you were using a 2009 backplane with a 2010 CPU board or vice-versa.
