I have a Gigabyte 1070 Mini where I changed the memory bank and for some time the card worked again. Now the card is not detected by the system. When the card starts all voltages rise but after a few seconds the GPU and Memory power turns off and the EN 2.4V disappears on uP9511p. On the second leg of Q519 there is 3.3V when the card starts but it disappears after a few seconds. The 3.3V comes from the fifth leg of Q130 and is missing because 3.3V on D505 disappears. D505 gets its 3.3V from Q511 in the last picture.

I am not sure where to look, and am unsure if I replaced the memory correctly.

1.8v rest up?

It works, there was still alcohol/flux under the GPU from when I cleaned half a week ago. I used a BGA rework station to heat the die and most of it came out.
