Nope, the other two are buffer and Mosfet driver (RT9619A)...
Still looking for the vmem regulator.

You can use these pictures to post on XS, I'll keep looking until I found that vmem-regulator.

Post what voltages you read at the big coils, side closest to the GPU.

More pictures would help, and what text is on those chips?

Nice, a 100k variable resistor between pin 4 and ground should do the trick...

Will do the mod tomorrow, test it and post a picture of the mod.
Maybe we also have to remove the current protection
