I got leadtek 7600GT, which is really good clocker, 640/830 stock cooling.
But i wanted to vmod it ad noticed that it has completely different PCB than reference and that nonreference card, that mods are already done.
So if sb with skill could help me figure out measuring points for vgpu and vmem and both vmods.
here is some high res pic of back side.

sb posted at vr-zone the link to vmod for this card, it's in russian but for all who did sth like that before, it shouldn't be a problem

Yes, this vmod guide in russian, but all u need is on this pic:

Translation:

Vgpu mod:
Vgpu controller: Richtek RT9259A (pin4 is feedback)
Default Vgpu = 1.3V
Pencil R37 resistor to increase Vgpu (440 Oм = 1.3V, 390 Ом = 1.57V)
Soldering method: connect 8K or 10K VR between pin4 of RT9259A and ground.
Vgpu мeasure point - see "точка измерения напряжения на ядре" on pic.


Vmem mod:
Vgpu controller: Richtek RT9214 (pin6 is feedback, pin 3 is ground)
Default Vmem = 2.01V
Pencil R36 resistor to increase Vmem (614 Ом = 2.01V, 550 Ом = 2,30V)
Soldering method: connect 8K or 10K VR between pin6 of RT9214 and ground.
Vmem мeasure point - see "точка измерения напряжения памяти" on pic.

thx for translation, i used some logic to figure the pics out, i'll do the mods soon.
