fragmasterMax,
There is no "link up point" so you can't use a single pot to do the mod. Btw, the resistors do not need to be SMD. 3 linear resistors (or pots) would do the same thing as long as they're ~1.2kΩ. 1.2kΩ is not a figure set in stone, a lower R value would weaken the OCP (and vGPU phase balancing) even more compared to 1.2kΩ, higher R -> vice versa. Higher R is only more safer, but a considerably lower R might be a bit more riskier. Don't go by a "too" low R value, though...
