    my new Mac Pro installed OS X + Windows 10 (UEFI mode), system RAM 64GB

    i've already got the 980 Ti working in EL Capatin (using automate eGPU master v0.9.8)

    however, i just cant get it working in windows 10, just like this:


    and i got this Error 12 (Code 12), This device cannot find enough free resources that it can use


    i tried to disable my two D300 video cards, still, the 980 Ti wont able to start

    i searched a lot topics, find "DIY eGPU Setup"

    first, i used the DIY eGPU v1.3 setup, it came with these messages:

    [ERROR] EFI/GPT installation found. You cannot do a disk image
    install. You have two options to get Setup 1.x working:

    1. Do a USB install, add an experimental UEFI framework to \config.bin
    directoru as uefi.iso or uefi.img and hope it chainload your OS whilst
    preserving the modified PCI config space.

    2. (recommended) change your partitions to MBR and set your BIOS to
    'legacy' or 'CSM'. SeeHow to Convert a GPT disk layout to a MS-DOS/MBR layout without data loss (and Gigabyte Hybrid EFI)
    for a non-destructive GPT to MBR conversion process.

    since my Windows 10 is already in BIOS UEFI mode, and i can't change my partitions into MBR (OS X is needed)

    then i tried with DIY eGPU v1.2 setup, followed all the steps in setup-disk-image.bat and reboot my nMP

    I choose DIY eGPU Setup 1.2, hit enter, see what happend?

    Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

    1. blah blah blah....

    2. blah blah blah....

    3. blah blah blah....

    blah blah blah....

    File: \eGPU\grub.exe

    Status: 0xc000007b

    Info: The application or operating system couldn't be loaded because a required file is missing or contains errors.

    dont know what to do now [​IMG]

    i contacted nando4, but he's in hostipal due to road accident

    thus he can't give me any further tech support right now

    so, im here to asking for help

    I think only MVC can get the eGPU work on the Windows side at this moment. And it seems EFI is required for the 980Ti.
