    Yeah, the OCP mod (from here) is NOT the OCP, it's OVP mod actually. It based on replacing (lower) the resistor, connected to Vmax pin of the PX-3540 (pin#41), but... The problem is, that with 8800GTS the OCP works earlier, than the OVP, so this mod can't help. But...
    As we know, the 8800GTS has 3-phase power conversion, so there are 3 resistors, that used for OCP (1 resistor at each phase). If we remove them, the OCP will disabled permanently. It'a a pity, that there is no exact pinout for the PX-3540 chip till now, so we can only guess:



    The red marked resistors shoud be in the OCP scheme, but i'm not 100% sure of it. Why Shamino keeps silence? I appreciate any help
