Palit 9800GT Vmod problem

[demon1122]

Hallo everybody
It's my first post in this forum
Sorry for my not good english
I have a problem with my graphic card, I would like to overclock
to 700+ on the core, but I need some more voltage.
unfortunately I can't find any info which way to execute that
I need to know where are the V-GPU measuring points and where should I to measure (and change) the resistance

Please help me if you can

Picture are in links below

Measure resistance between green dot and ground, solder a VR rated 20x the measured value between the green dot and ground. You could probably find an unused soldering pad near the green dot that is connected to it...



Measure vGPU voltage at blue dot.

Don't forget to report the results.

Don't forget to report the results.

I promise to report
but first: thanks for so fast replay
now I need a proper solder gun and... some luck
If I'll only do something, you will know first

I use that: http://www.allegro.pl/item461676917_...w_solomon.html
It comes with 0,8mm soldering iron, but I recomend to buy 0,4mm (I use 0,8mm, but sometimes it's hard). It's cheap, but if you want make one or two mods, you don't need anything better

Hallo again!!!
Sorry I'm late but I didn't have the time for the computer.
Largon - you are great
I have made Vmod, and... everything is still working.
Vgpu stock 1.06V after Vmod 1.26
clocks:
Core 600 2D 800 3D
Shader 1500 2D 2000 3D
Memory 500 2D 1000 (2000) 3D
temperature:
before Vmod 50 (3D load)
ater Vmod 64 (3D load)

But... I am not an executioner and I put the voltage on 1.22V and Clocks 750/1875/2000
