IS7 vdd vmod with pics...
All credit belongs to Learn over at XS for discovering this mod
excuse the really crappy quality picture, tis what happens when a scanner is used instead of a digital camera
In order to increase Vdd we must remove R115 and replace it with a 20 or 50k pot.
heres the location of the R115.
Remove R115 and solder two legs of the pot into its place.
I set the 20k pot to 4.35k which was the resistance i read from R115. To raise the vdd voltage increase the resistance on the pot.
as with the IC7 the vdd is measured from the mosfet above the agp slot towards the socket.
We are also in the process of workin out the vagp mod... hopefully it will be updated shortly. Any and all questions will be entertained.
