Thanks roger
@ Benchbros.
Vgpu 1.52, Vmem 1.63
This card has typical behaviour. from 1.5V Vgpu the screen will go black at -33. if we pull the card to -67 sometimes the entire screen would shut down @ -52. if that happend we needed the extra card and a few powercycles to get display again.
It was quite a challenge to understand the cards behaviour, but it payed off
