NOT yet! You must check your voltage first! Show me the backside of your card. Or just find a picture of it on the internet.
When you know what the voltage is and where you measure it, you can start turning the VR while measuring the volts.
One of the yellow spots is vGPU, you can try all of them to find it. If it's 0v it's ground, if ~12v it's input voltage and if it's ~1.1v it's vGPU.
Now it's pretty much straight forward. You know what to do right?
