Hi,
 
I have a MSI 260 gtx 55nm REV 1 NCP 5388 card.  I want to volt mod it and have read quite a bit on volt modding.  I couldnt find any info or guide for the 260 gtx REV1, could find 280 285 all day long and 260 rev2, which i think is the ncp5395?  Anywayz heres all info i dug up so far.  Heres a pic i dug up on the mod.  Looks like pin 19 to a variable resistor to ground
 
 
 
 
I measures resistance from pin 19 to ground and got 12.25 k ohm!! Only variable resistor could find is a pot 250k ohm one, about same size as the ones they used in this mod.  Does that sound about right?  Seems a little large compared to other mods...
 
heres a link to the data sheet

If you can provide any more info be great.  I'm kinda going into this blind, i got no real guide to work off of and no images of 100 percent confirmed working mod.  I think in those pics they were able to short out the OCP and move it to a useful level.  They did run into a OVP after 180mv from stock voltage.  I cant find anything about how to get past OVP or pics of anything else really.  I tried another site but kinda dead in the water on that site also.
