Befor the mod: resistor: 1,612Kohm vgpu: 1,24V (idle) / 1,29V (load) Max stable clocks: 700/2100 Max bench clocks: 730/2200
After the mod: resistor: 1,402Kohm vgpu: 1,24V (idle) / 1,32V (load) Max stable clocks: 730/2100 Max bench clocks: 760/2200

I try to set lower the resistance and post results.

2 added measuring point is the same that yours, but i easy to measure when the card is in my case.
