Truenas CE 25.04.2.4 not booting with Ryzen5 5600G & Gigabyte RTX3060OC 12GB

Hello I have a truenas instance running on:
Gigabyte B550M DS3H motherboard.
Ryzen 5 5600G
Gigabyte RTX 3060 12GB.

I want to passthrough my RTX so I swapped my Ryzen 5 5600 without integrated graphics for the one with but now my nas wil not bot at all the moment my RTX is connected. Previously (when there was no integrated graphics in my CPU it was running fine. It looks like somehow the iGPU and the RTX ar competing in some sort but I can not seem to find what might causing the issue. Asked the famous chatgpt for help but he keeps telling me to change the bios to this which obviously doesn’t help.

3. Settings → IO Ports

Ensure:

  • Initial Display Output = IGFX (forces onboard GPU display first)
  • Integrated Graphics = Enabled
  • Above 4G Decoding = Enabled (required for VFIO passthrough)
  • Resizable BAR Support = Disabled (optional for stability)
  • PCIEX16 Slot Configuration = Gen3

4. Settings → AMD CBS → NBIO Common Options

  • IOMMU = Enabled

5. Boot

  • Fast Boot = Disabled
  • CSM Support = Disabled
  • Boot Mode = UEFI

Is there anyone who has the same issue with this?
