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

I've done it as well sometime ago but it was buggy.

Yes.

Since you are using Z270 motherboard, you probably don't need EmuVariableUefi in /EFI/CLOVER/drivers/UEFI/.

Please try removing it. If it works, you should get kernel panic logs if/when you get a kernel panic. This will go a long way to helping figure out what's the cause of your crashes.

I will try removing it. Would there be a benefit for me to go to 18,3 with IGPU enabled? I think I am pulling good numbers here.

IGPU should not appear in System Information when configured to be headless. Maybe that was the problem.

Check their hackintool there is headless metal and it says NO.

iMac18,3 is a closer match to your hardware. There should be no downsides to using it.

Remember, iMac18,3 needs IGPU to be enabled in BIOS.
Set Primary Display to PEG (or PCI depending on motherboard).
Allocate at least 64MB to IGPU.

hackintool was no for headless metal if i remember correctly, the bottom two options were no

I don't know if that matters or if it means anything... I have IGPU enabled on my Skylake box with RX 560 and it also shows Metal Headless No...

In my case, Metal works. Usually I use XMP I, but now I'm testing ASUS Overlocker AI, so it is turned off.

I do not observe any problems related to the AMD 5700 XT on Catalina 10.15.1 in my case.

The only thing is, for some reason, my computer leaves sleep mode 5 to 10 minutes after diving, but then falls asleep in 1 to 2 minutes and does not turn on anymore. I think this is due to Catalina, not the video card, because I used to use Mojave before.

So is everything running well for you guys now?

Everything is working stably for me. I do not see any freezes. There is no flicker either.

I have been using the computer all day - there are 0 problems.

The Sapphire RX 5700 XT Pulse card performs well.
