What SMBIOS are you using?

What SMBIOS are you using?

It's macpro 6.1, I also used the AGDPfix to get signal out of the first gpu.

Have you tried any other SMBIOS like iMac14,2?

I just tried and didnt boot. Also regardless of imac14,2 or macpro6.1 I noticed this error during boot in verbose. I think this is the key to the solution but I cant understand where is this BR3A.GFX0 it says. Its not on my DSDT or SSDT files. Any idea how to fix this error?

I think this is something that would need to be addressed by someone who knows more about SSDTs and reading IORegistryExplorer. I saw that you posted in the other thread.

Yes I posted in the other thread because the patch didn't worked for me, maybe I am reading something wrong from the IORegexplorer.
Unfortunately the system don't let me contact them directly with a p.m., I dont have enough messages

They will both get a notification that they were mentioned.

Hey, I'll try to help. I'll need to know what your system specs are.

What motherboard?

What version of macOS are you on?

Also, (with both GPUs installed) please boot into the clover GUI and press F4, wait 10 seconds and boot into the OS (with nv_disable=1 if needed). Mount the EFI partition zip your entire CLOVER folder and post it here.

I am attaching the EFI partition per your instructions. I used nv_disable=1 with both gpus installed to be able to boot into the desktop.

My system is i7 5960x, 64gb ram, SLi 980ti, Asus rampage v motherboard. I am on Sierra 10.12.4
