Memory Voltage Mod
Locate the chip labeled "51117" on the backside of the card. A 200 kΩ variable resistor is needed for this modification. Solder the variable resistor on the pads pin-pointed in the instructive picture above.
Monitor the resulting vMEM memory voltage with your multimeter: Red probe to the either of the two points marked inside the yellow rectangle (see paragraph: Overview), black probe into a ground. Default vMEM voltage on an NVIDIA GeForce 9600GT is 2.00 V.
2.10 to 2.20 V is usually enough to push the memory frequency as far as it possibly goes.
Your milage may vary.
