I am trying to hard mod my x800pro PCI-E to 16 pipes. However in addition to the laser cut, I believe there are two reistors placed differently, or missing, on the 12-pipe x800pro that keep it at 12 pipes. I think one of the resistors is on the gpu packaging, but I really have no idea where the other one is.
Anyway, if anyone knows where I could get good high-detail pictures of a 16 pipe, r423 card, front and back, with the heatsink off, I would appreciate it.
