XFX 6800GT PCIE Vgpu Measurement Point?

[MikalCarbine257]

I have an XFX 6800gt PCIE (I think it is the Nvidia reference board) and I am going to vgpu mod it soon, does anyone know where the measurement point for vmem and vgpu are? (most importantly vgpu)

The back seems to be identical to this nvidia board:
