It seems you have grasped the basics of OCP, it makes sure your vcore doesnt reach a certain point that manufacturers have deemed dangerous... it will either crash or drop your voltages back and ruin whatever benchmark you are doing.
Your 8800gt most likely maxes out at 1.1/1.15v volts when it is flashed with additional volts on the vcore. OCP will generally kick in over 1.4v, generally around 1.42-1.45 depending on your DROOP. Capping and inductors/chokes can helps stop the fluctuations in the voltage and allow you to squeeze out extra clocks before touching that OCP level. (CL3p20)
Pretty much a OCP mod will trick the card in a number of ways to manipulate that trigger point or completely disable it. Post some pics of the mod area of your 8800GT and the number of the PWM/IC that controls the vGPU. VMEM doenst have an OCP that I know of, its only protection is suicide when you crank it too high...
thanks, explains a lot, so if i flash the bios to 1.1v stock, it will raise the OCP trigger level?
So it triggers when one leg of the IC is higher than specified? Well, what would happen, if you cut the leg if the ic that it monitors?
eg: its rule might be "if pin x is higher than value y, then trigger ocp"
then couldnt you cut pin/leg x of the ic so it is getting 0.0v into it? because 0.0v is not higher than the specified value(1.4v or whatever)
edit: and for the ocp mod, my card seems pretty referance, heres pics, they may or may not help, they were showcasing my mod :-):
