ive had a long google for the info on this, and i found some pretty helpful sites but due to the age theres no pictures anymore.. i was wondering if anyone here had v-modded a standard 6600 pci-e and wether they could help me out, i want to try the pencil mod first as its not permanent. so what i need to know is where i should be pencilling. i understand its one of the resistors in the power circuit, but im having a hard time locating which one. i followed one guide but the nuumber of the resistor was one by a memory chip not the core i can add photos of the car if required, its an msi 6600 and is just reference anyway.
