Hi to all, i have searched all over internet, but i haven't found anything accurate.
I want to vmod sapphire 5770 vapor-x graphics card.
This is a pic of the volt controller

and here (http://www.google.it/url?sa=t&rct=j&q=ncp5395t&source=web&cd=1&ved=0CCYQFjAA&url=http%3A%2F%2Fwww.onsemi.com%2Fpub%2FCollateral %2FNCP5395T-D.PDF&ei=96M_T_eFIaX44QSvidniAQ&usg=AFQjCNGczqgmpf39CWCIN4JR-ASN0-coAg&cad=rja) its datasheets link.
Could anyone help me?

If you looked by google, you shoulded found it, but i gues you didn't ???
Take me 3min or so to find it.

Yes, i've found it, but if you see better you notice that in that thread don't talk about NCP5395T, so i don't know what is the right resistor or the right pin to put it.
Infact i have wrote:

the model of resistor you can find out yourself.
Start with a small one, and go up untill you are on max Vcore

I don't know that you will gain anything over Afterburner, as you can volt mod in there? Unless your talking LN2 in witch case disregard, but if you do find something I'd be very interested in it!

measure the vFB pin to ground in ohms....Then follow the trace from the pin down to a resistor below, make sure it has the same ohm reading. Multiply that value by 20 and use a VR of that value or slightly greater to the resistor you found to ground.
IE vfb measure 1k. 1K x 20 = 20K VR.
