Hi guys, can you help me please?

I don't know what else can I try to do... my EFI is not working, I usually used a Hackintosh on my other computer (Intel i7 10700k) and changed to this one on the subject

It starts, i fill the password, hit enter, the post start but the computer restart

Tried everything and can't make it work.

Anyone can help me?

Here is the log of the errors attached and my config.plist

Hello @lfbaptista For more help please zip and upload your entire EFI folder without serial numbers, the config.plist and Opencore log files only tell half the story. At first glance you have SSDT-CPUR.aml listed in your ACPI section of your config.plist but its not enabled, its required for all AM5 motherboards.
 
@lfbaptista your opencore log are not useful because they miss of many usefull data as MMIO area
for now i have bypassed to build a proper MMIO whitelist area but in a future you should do it well (also if you luckily boot fine with this)
Also, your cpu is a 12 cores cpu so 08 was wrong as cores count
If you like try in the same EFI this config a see if you do a step forward
As suggested before is better to include a complete EFi to be helped in a better way and for a proper SYSREport folder and log you should use Opencore Debug version

I suggest to create ACPI/SSDT file with CorpNewt SSDTTime tool using it in windows and seen your resizebar parameter in cfg also to set 4G and Resize bar on in your motherboard bios
