asrock x570 taichi + radeon 5700xt SUCCESS!

[baronerosso]

Hi,
I can install BigSur without problems, recover my account from the old mac hard disk, but when rebooting ... black screen.
Asrock x570 Taichi firm.3.80, Ryzen x5900, Sapphire Radeon rx 5700 XT.
I have success booting the first time with Fenvi t919 but it doesn't work on BigSure, so I used IntelBluetoothFirmware.kext; rebooting very slowly and the next reboot... black screen nightmare.
This is my EFI folder https://github.com/baronerosso/asrock-x570-taichi-5700xt

HELP!!!

I quickly looked through your EFI, a couple of things I noticed:

• XhciPortLimit should be disabled
• SecureBootModel you could try with disabled

Other than that I didn't see anything obvious. I had similar issues with older versions of the IntelBluetoothFirmware.kext in the past, but the newer ones should work better.
I'd start with going through the BIOS again, rechecking all the settings, also make sure your GPU is set to PCIe Gen 3.

We are in the most total absurdity

I redid the efi folder, installed without recovering my account, clean.
Reboot with USB inserted and everything works.
I copy the efi to the hard disk EFI and ... black screen.
I restart with the USB inserted and it works.

I do not know what to think

I have 2 nvme and 2 SATA, I install on the nvme which is recognized as external.
Could it be that?

 

[Aluveitie]

Did you try plugging of the SATA drives? or tried connecting them to different ports?

 

[baronerosso]

WAIT!!!
Swapping nvme, copy efi from USB again e now ... boooooot!
Now try Migration Assistant ... waiting

absurd, it works randomly
The problem is the Radeon 5700Xt.
The system starts, I enter remotely with ssh without problems.
The oddity is that they are unrepeatable situations, now it works and after a reboot ... no

give this a try dude:

GPU Performance Improved

Over the past few days we’ve been looking into why the GPU performance was lower on an AMD hackintosh and narrowed it down to one patch. After many tests and reboots we can now say the issue has been solved. Patches have been updated on the AMD OS X GitHub...

I see in your shared EFI that you have algrey - mtrr_update_action instead of @Shaneee enabled, try switching that up

Cheers!

Ok, everything works!!!
Thanks @MagicMANX
Thanks @Shaneee patch!!
Thanks you all for support!

Wifi ok without Heliport
Sleep/wake ok

Only one thing remains "strange": if I remove -v from boot-args the problem of the black screen returns.
Verbose boot isn't something that bothers me, but I don't understand why it affects it.
