no magic - bios with support for working without 4g decoding.
but 110 watts is too much for a card like mxm-a, so I tried to find something closer to 50-60 watts using the techpowerup bios database, but none of those video bios files (from laptops I guess) m17x r4 didn't want to start (apparently they require the 4g function in the system bios. The 4070 may well not have the original working video bios and you're just left with that card.
Plus, it has high elements on the right side of the chip, which prevents normal cooling pressure. and 8 pcie lines are not very encouraging either.
I don't really see the point in newer cards because there is a guaranteed problem with the bios and also with the quality of chinese boards, so for alienware I will probably limit myself to adlink's rtx5000 - a reasonable maximum for the processor.
