One final thing... what exactly is the procedure for this? Solder the red point (or one of the orange optional points) to a wire, the wire goes onto the variable resistor while a ground-soldered wire goes onto the other leg of the VR? Set it to max resistance, and then... ? How do I measure the vGPU exactly, with a clipping multimeter leg? How do I determine the actual voltage with these cards? Sorry for so many noob questions, but better safe than sorry on this .
