Need pencil mod for DDR2 on 7600GS.
PWM is CAT7580.
Default V is 1.87V

There are 2 resistors from FB to GND!
On both are 562 Ohm resitance.
When I lower it, like on many cards before, I gain lower Voltage instead higher?
Example: 555 Ohm give ~1.8V ...

There is no other resistors between FB & GND. I was looked all over the card.
Can't solder VR currently...

What's the catch on this card? :)

if you lower the resitance you will get higher voltage. all you can do is try dropping it like 10-20 ohms to see if your voltage is going up and then you will know you have the right mod.

I know that but do You read my post? :)
Do You think I'm go to lower resistance on wichever resistor and monitor Voltage to find pencil mod?
