6800GTO Help

I just recieved my Dell Dimension 8400 with a 6800GTO. I have read through the forums about being able to unlock the extra 4 pixel pipes, but mine seem to be disable no matter what I do.

Any suggestions or is this hopeless for my card?

Most new GTOs randomly stopped unlocking towards the end of october. Seems that Dell/nVidia started physically disabling the extra pipes/shader after word spread about riva-tuner mod... meaning softmodding is a no-go, sorry. Then again there always is soldering
