Good thread, thanks for the information. I have been testing these mods on a eVGA 7950GT KOSC and I think I am having some problems with overcurrent protection.

The 'K' resistor you mentioned was ~80khz on the 7900GT is 50khz on the 7950GT, so it looks like they changed that similar to what you had mentioned.
They have already connected the B and C points on the board for increased voltage.

At 1.55v I can get to 740mhz core stable, however, if I try 1.65v I get a black screen at anything over 700mhz in 3DMark05. I tried soldering the 47kohm resistor like you mentioned for the overvolt protection, but it did not change the black screens in 3DMark05.

Any ideas on what I can try? My 7900GTX did not have this problem and could be run as high as 1.8v without problems. This is on a waterblock from Viper John with loaded temps of 40C.

Thanks!
