Default [M] Extreme Geforce 8800 GTS Modification: OVP Removed

Like I said, the voltage over the Capacitor of the RC network is being read into the controller, inside the controller this signal is compared with the voltage level which we made at the OCP pin. The higher the current flowing through the inductor, the higher the voltage over the sensing capacitor (Cs), and the closer Cs will come to the voltage level applied at OCP, the over current trip point. After OCP has been tripped the controller will shutdown itself in order to protect itself against any damage and your pc will most likely freeze or reboot. We can work around this be changing the resistor values at the OCP pin, though we don't have any specific details about pin connections and functionality with the Primarion PX3540 PWM controller, we are forced to find out how the RC-network works so that we can manipulate the signal that is being read by the controller.
