There won't be a difference because both cards have vmod points of the same size

Those are the areas of which we need a close up picture:

On the pics you can see the points where you will have to solder on later.
Before doing so you have to measure the resistance between those 2 pins(ground and feedback) of both ICs/chips so we know what kind of variable resistors you will need for the mod.

Start at 200k Ohm and then turn it down step by step to get more accurate values.
It's likely the resistance at those spots will be between 200 and 2000 Ohms.

20k readings sounds weird.

I would recommend using a 20k VR for the vGPU mod.
