Thank you, fabiosun. Do I understand right that problems with video and system stability do not depend on the DSDT? Who could advise what to do with my EFI, What's wrong there are

The link does not work for me

@etorix no, is it suitble for X870E ?

I would like to ask for a patching DSDT for the X870E Taichi Lite. My skills are too low for modifying the DSDT by myself. Or maybe will advise so I can try patching it myself. Thanks! DSDT.zip

still in the same condition :(, nothing helped yet...

agdpmod=pikera. seted. 4G Decoding - Enabled Which one? Booter quirks ResizeAppleGpuBars 0 Uefi quirks ResizeGpuBars -1

Disabling the Gatekeeper did not help the result is the same

boot with 2 DP - black screen, resetting... disconnect 1 DP, booting with 1 DP - black screen second try 1DP, booting - black screen boot from USB - the screen appears.. something still wrong 😞

Thank you, fabiosun, for your fast reply! Disable whatevergreen, it boots much faster, and disable applealcu - the result is good, the sound is on will try to boot with 2 DP ports

X870E Taichi Lite uses Realtek ALC4082, everything I find about it is like USB audio, somewhere I read that it needs to use AppleALCU but will try without also...

EFI.zip I think yes, could you check my efi Without whatevergreen never tried, will try..

I made a build based on an x870 Taichi Lite, AMD 9950X3D, 6600xt, NVMe, and 64 GB RAM, and use your @fabiosun efi. Of course, I made some changes for my devices, but still, something is wrong with the video. After booting, everything disappeared, a black screen, and after about a minute, the screen appeared. Booting just with the middle DP, if connected to 2 screens, will result in a black screen. If I boot with one middle Display Port and after the login screen, connect the second screen, everything is shown. What could be a reason?

Do not execute or close after a second 😞
