dell aurora r10 (3800x) wont output video with A770

[Danrdz10103]

I used sucessfully my A750 and A770 on an older Threadripper 1950 X399 with ReBar enabled and active. 

But now that I tried to install the A770 to a Alienware Aurora R10 (Ryzen 3800X), I dont get video output. Video says no signal received. I tried at least two GPU ports on the back of the GPU. GPU and computer fans are running and GPU lights are on, but no video output.

any workaround? 

the machine was working fine 5 minutes before with AMD 6900XT (I clean removed all AMD drivers) and rebooted before installing the A770.

Any help appreciated.

Try 

BIOS update

Disable SVM (virtualisation) in BIOS.
