Thank you for pointing out power issues.
Looks like it's a common issue with Aurora machine:

Out of the box, the card is wired to one power supply cable, split into 2 connectors (6-pin and 6+2pin).
Power supply has a 2 GPU cables, so rewiring one of the connectors to feed from a separate cable seem to fix the problem. It's running now in the combination cracking mode, which I couldn't use before.
Hope it doesn't fry the card due to improper grounding.
