Well i checked with the 100k resistor and still NO-GO!
I dont know whats wrong..The pencil mod works though...

Thread Starter 
that picture suggests you use a 20k, i;d start with 25 or 22 though to narrow down the voltage

also, my experience has led me to use voltage resistances far lower than tutorials suggest, like for instance last tutorial I read suggested a 500ohm resistors, I needed 100-200 to get any meaningful voltage change, now im rocking out 68 ohms and what I think is a successful OVP mod so who knows what my limit will be

meanwhile at 68 ohms / 1.44 volts at load, the electrons in my card are yelling at me in displeasure!!!

Maybe u are right
maybe i should buy a 10kohm and have more sensitivity in my regulations...

@ the doctor- those be your inductors whining..make sure they are getting a full 12v to their input and keep them cool..it will help reduce the squeal somewhat..adding caps to output phases will also help buffer the changes in voltage that the inductors are dealing with...

What is the resistance value of your mod point?

2.35kohm STOCK...I checked with a 20kohm too...
nothing happened...
maybe i do something wrong....
I think i ll desolder and do it over again....

2.35kOhms x 20 = 47

A 40 or 50KOhms VR would be safer.

I ve tried 20k,40k and 100k...Nothing worked...
I ll try to resolder although i am sure its connected properly.
Maybe OVP??????????Cos of the 3 mini volteras ICs...?

hmmm, sounds like its not the right mod point. Which card/thread where you modding from? I'm sorry, a lot of modding here lately and I've having a hard time keeping up with who is modding what, but that's a good thing.
