Ok..so, now do you have continuity between points:
5.5k -> pin13 or 6.4k->pin13 ? ...check for continuity on the mem points as well... if you have confirmed continuity between 2x of the GPU points and the listed vmem points, those will be the mod locations.. I'll wait for you to post back...

The one in the picture on the chip? Also how exactly do i measure continuity? I was useing the resistance setting that i guess is wrong. I think im on the continuity setting now, so do i need to have the card plugged in and powered on then test? Researched. Results in a sec.

Ok.
So i get no continuity thru 5.5k or 6.4k. I tested some others and found (in pink) one that has continuity and a resistance of 1.14. Also the mem has continuity.

 ...I think you forgot to post the pic..1.14...Ohms..or K-Ohms..? Either way sounds much more realistic..and spot on the stock voltage as well  is it a resistor or pad..? As for mem..that will be the mod point...so 20*measured value = VR for mod
