You don't need other modification to install this driver in Win8.1

The GPU it's not detected by default in W8.1 (it doesn't appear on Device Manager). You can read it and see screenshots in my previous threads

I managed to get it detected on build 9888 on Device Manager without yellow marks. But when I install the driver I get black screen flickering and I need to restart to safe mode and uninstall it.

By default 9888 doesn't detect it but (if some user interested is reading this) you can port a .sys file from a previous build and the GPU appears on Device Manager.

I think it couldn't be so much difficult to get it working in this build but it needs more testing since in other builds I didn't get black screen cause and also nothing than a yellow mark, the screen didn't changed and nothing. So maybe the direction to test the drivers is this build.

Why do you think it gives me black screen flickering?

Please, read my other thread, I explained here one year ago.

One question: Can UEFI boot affect non-signed drivers if I boot with 7) Disable driver signature enforcement ?

@voug
You walked on your own way without success.
Try something else.

Do you think you can help me if I send you the bootlog of windows?

At first you need to install clean Win8.1 (from MSDN) without any(!) additional drivers.

Hi! You from Russia? If yes, can I write you in VK? I didn't really understand
