MOBO is X399D8A-2T
I just changed my A 5000 ADA into compute mode and now when ever that card is installed I get this Error Code DE AD DF 19 04 65 I need help figuring out what this issue is. I can't get to the BIOS and the board doesn't post with the card installed. |

Yes pull the card and then change the Bios Setting Above 4g Decoding.
Also anable Ase Cap for stability if you are trying to use vgpu. Another Note is also now you will need to use (if you PXE boot) another lan not the onboard lan for PXE boot and you can't use Legacy you need to use uefi. The Above 4g Decoding does something to the pci lanes on that bridge I read from a supermicro post that as a similar setup as this mobo. |
