@CaseySJ - First, just want to say how great your guide is. I had some experience with Clover hacks in the past but this is my first time using OpenCore. Only hardware difference from your build is I used i9-10850k and Crucial ballistix RAM. I am also only using iGPU for now. Installation was flawless and everything seems to work including TB3, all USB ports, sleep/wake, handoff, AirDrop, etc. I did have a problem with sleep when I tried the YOUBO Fenvi card. I traced it to the USB connector. This resolved when I replaced the YOUBO with the Fenvi card you recommended. I have no idea why.
I do have one small issue, Intel Power Gadget 3.7 does not appear to be working for me. The program seemed to install without error but I get the following pop-up when I load the program:

Even after following the above instructions I still get the above pop-op and obtain no readings:

I do recall someone having the same problem on this thread awhile back but do not recall any follow-up or solutions. Its obviously not a major problem but just wanted to run some tests on the system. Any assistance would be appreciated. Thanks again!
