RX570 requires vendor-reset (lots of threads about that on this forum). See if it works with Ubuntu 24.04 LTS installer to make sure it's not a Windows (driver) issue. And make sure you see reset messages in the Proxmox system logs from vendor-reset.

I can pass the GPU to an Ubuntu VM, also i played games on it, i have the vendor-reset installed, tellme what command do you need to run.

this appear when i run the machine:

Hello Ciroloco! The PCI Passthrough wiki page contains a chapter on Error 43 - could you please check it out and see if it helps?

I check this and in bold my answers and questions

• Try passing the PCI device to a Linux VM ( The GPU works in Linux Machines )
• 
  
• Try plugging the PCI device into a different PCI slot or into a different machine
• Check the security event logs of your Windows VM ( What have to say ? what kind of error ? )

• Check the dmesg logs of your host machine (Same that above )

• Dump your vBIOS and check if it is working correctly. ( Tried , an error appear and cant dump the rom
• root@proxmox:/sys/bus/pci/devices/0000:01:00.0# echo 1 > rom
  root@proxmox:/sys/bus/pci/devices/0000:01:00.0# cat rom > /tmp/radeon570.rom
  cat: rom: Input/output error )

• Try a different vbios (see the GPU requirements section) Changing the vbios could generate problems ? fried the GPU ? what bios do you recommend ?

• If your GPU supports resizable BAR/SAM and you have this option set in your BIOS, you might need to deactivate it or manually tweak your BAR using an udev rule (see Code 43 while Resizable Bar is turned on in the bios in the Arch wiki)

I cant get into the bios maybe because Proxmox is installed has UEFI Bios ? there is a way to boot directly into the bios?
