I can't find a 9600gso vmod with the pcb of this pny one. can someone help me out?

Thanks, let me know if you need more pics.

OK, the chip on the backside most likely controls VGPU:

Please give me the exact name, as the pic is too blurry.




The AWP7067N on the frontside supposedly is dealing with VMem:

Pin#4, marked in red, is FB and pin#7, marked in black, is GND.

To be sure that it's for Vmem, please measure voltage between FB and GND, and also between pin#6(FBL) and GND.
Then shut the system down, disconnect it from the socket and measure resistances between the named pins.

VGPU Chip: apw7088

i will be back with the measurements.

Resistance between pin#4 and GND - 612 ohms
Resistance between pin #6 and GND - 1536 ohms

OK.

Pin#13 is FB and pin#4 is AGND (Analog Ground, that means you should measure all voltages in reference to that).

Find alternate soldering points for these pins and measure resistance between them.

Edit: Remember, the dot on the package marks pin#1. ;)
