[Solved] 10.15.1, updated kexts, pastrychef-verified EFI, 5700XT freezes in OS

I cannot get 19,1 to show as fully supported using your EFI. So... I don't know what to say about that.

 

[pastrychef]

I understand this is good?

Do you need to change anything?

Yes. That's good. You have IGPU enabled. I was told IGPU needed to be disabled for 5700 XT to work. I guess that was wrong.

 

[piano08man]

Trying that now I guess.

You need to enable IGPU in BIOS for it to show as fully supported with iMac19,1.

I used @ModMike recommendations when setting up the BIOS for working with discrete graphics. They are in the topic Z390-I.

I'm stress testing the EFI right now. I'm showing as fully supported. Please don't freeze.

Check your memory and CPU use at the time that this happens.

One noticeable difference right off - AppleALC is at 1.4.1 instead of 1.4.3 that we were using. It's also not the updated clover, but idk if that would actually make a difference.

 

[piano08man]

nope, already frozen.

nope, already frozen.

Radeon VII is on sale right now on Newegg, I was considering that when this did not work for me.
