i had the volt mod done on my 8800gt running at around 1.35 volts under load w/o any problems, i even did some thorough testing but wasn't getting much stable above 780 core and 1950 shader, so i thought the ocp mod might help out, at first it seemed that the ocp mod was helping out w/ stability at higher clocks, but then the temp was rising a little higher than i wanted it to, around 70, started to throw a few errors, and then the comp shut down. The comp would not power back up again, gave a loud whining noise, everything powered on fine w/o the 8800gt power pin in but nothing on the monitor, so i popped in my 6600 and it worked fine, so i had a dead 8800gt after the ocp mod at 1.4 volts load. just thought i would let you guys know. I got the 8800gt replaced, but I doubt i would run over 1.3 volts now and I probably wouldn't do the ocp mod. Maybe I just had some bad luck, who knows, but the soldering was done perfectly. used 1.2k resistors for the ocp mod also.
