my core VR grounding point is also vRAM readout point

would that make a difference?

NOOO!!!

LOL


Incorrect ground point for sure.


Put your multimeter on the continuity setting (where it makes the beep noise when you touch the tips of the probes together) then hold 1 to the backing bracket (where the VGA/DVI connectors are) and probe the card to find a point which "beeps"... usually a ground leg on a capacitor or the 4/6/8-pin power connector works fine...


EDIT

I think we should clear something else up here

The point of a voltage mod is to create a divider in the circuit. The sensing pin (FB) sees X voltage and put placing the VR in parallel to the pin sensing voltage it draws away some of the power so it thinks the item getting X voltage (in this case the GPU) isnt getting enough and it overcorrects. If you do not use a point that is grounded then you have a lower potential to work with (or in your case a negative potential).
