OK, I had it removed before and it didn't seem to change anything. Thanks Feartech

as mentioned, it doesn't do anything on it's own

you wouldn't see any difference in your setup with it enabled or disabled

Yes I understand. I am trying to work with this atm: https://gitlab.com/vectorseven/ochack
as it seems to be the source.

You should use my High Sierra EFI's from the newest post (or the file I'd given you, which is customised) because they'd been refined from the OCHack's source. The OCHack file is severely cut back with missing elements in the config.plist (compared to a normal OC file), and will crash your system if you try to upgrade to say Catalina or Big Sur. I restored most of the missing elements, while making sure it works in High Sierra and beyond. But you may need to add your AMD card's device-id in the device tree properties in this way ie. (49520000). This fix should work along with the AGPMInjector kext to boot.

Also one thing I also forgot to mention, to boot in your system, Above 4G Encoding may need to be disabled. On Gigabyte boards they're known to be an issue.

Either one, I seem to be stuck with the same result. Something (I think basic) that I am missing. I will spend some time on it... will check 4G Encoding and device-id.

Thanks MIddleman.

Hi Middleman. I have a motherboard Gigabyte H470M DS3H, i7 10700 and GTX Titan Black. I Try to install High Sierra with your EFI but I have an apple logo loop, imposible to install SO. I've moved to Catalina, but I need the CUDA acceleration for some 3d works, Catalina doesn't have Cuda acceleration for my graphic card. I would like to install High Sierra, would you help me?
This is my PCIe system on Catalina:

Thanks for your good work.

Thanks for your good work.

Hi Rafaes75,

If the first EFI didn’t work then you could perhaps try this one >

Use the High Sierra EFI folder from this post, insert your board serials, ROM, UUIDs and enable your iGPU in BIOS but try booting from your Nvidia card HDMI instead. You may have to use nvda_drv_vrl=1 as a boot-arg also but it should work.

No way, same result. Can't install SO, apple logo loop.
If you think about something else...
Thanks a lot

Try to install it without the Nvidia card - remove the card from your system and use the Intel HDMI port.
Then change the AAPL,ig-platform-id device properties of the Intel UHD Graphics to 00009B3E and make sure the device-id is also 9B3E0000.

No results, impossible to install. I put to see the console: "End RandomSeed" anyway.
Thanks a lot, really. It's difficult to find the solution, I know.
