Try using the empty solder pads to the right, that would normally be occupied by some SMD capacitors. That's a better place to measure the real VGPU, because it is behind the inductors and not before them, like the points you marked.

And concerning VMem: One of the two AWP7065 probably regulates the memory voltage. Question's just which one (I would guess that it's the upper one). Some esaurements should clear that up.
