The 980 is in the wrong slot, move it to the x16 slot, restart
Post #1/cloverHDMI

My Nvidia Geforce GTX 980 is in the third PCI-E x16, because I have the Cryorig R1 Universal. It´s a big cooler and I want to have more free space between the GPU and the CPU cooler.
So should I move the GPU to the first PCI-E x16 slot?

An answer would be nice.

There is only one x16 slot.
No idea on your use case, why own a high end graphics card with compromised performance?
Yes.

Yes.

Thanks toleda, that worked.
I looked in my the port I used was PCI-E x16 2.0, now I´m using 3.0

That is not how it works, both connectors support PCIe 2.0 and PCIe 3.0.
One connectors supports x16 or x8 (if 2 graphics cards)
The other connector supports x8 only

Finally, ssdt is working.

I tried this in all 3 of my display ports with no luck. I turned off my computer each time I switched ports. I also tried using a DVI2HDMI no luck there either. I can send you those files if you want me to. Please just let me know.

What is "this" - DP2HDMI, 2 cables, other?
Make and model of display?

“This” is what’s shown in the picture. Display Port to HDMI.” It’s one cable. I’m using an LG TV. No idea on the model.

I have a problem. OS: 10.13.3 17D47. Build: "Haswell mini-Cube" as in my builds just under this post, specifically: MSI H81i, 8gb DDR3-1600 (one stick,) G3258 @ stock (3.2Ghz,) GTX 760, Sandisk 128GB SSD, UEFI: E7851vA6 (the latest, full version string: H81I / H81I-S01 / H81I-S02 (MS-7851) V10.6) I used cloverHDMI. I have run cloverHDMI and it detects that no hdmi audio codec is installed. I let it run and install the PEG0 ssdt in EFI/Clover. However, it does not work. Every time I start up again the script says the same thing: that Nvidia HDMI was not installed and reinstalls the ssdt. My cloverALC audio always works no matter what. I am running the latest Nvidia Web Drivers (387.10.10.10.25.156) and they work great. All required files (and some notes on how I edited my files) as in Problem Reporting are in the attached zip. Thanks in advance. I appreciate all the hard work you guys put into making these great tools, but they are unfortunately not working for me.
