If i'm not mistaking, this is the first working VDD mod for the AN7. First of all, it's not like the DFI Infinity mod, or like the NF-7/S mod, those mods are simply not working on the AN7 because it uses different circuitry. All you have to do is to connect a 25K pot from pin G(ate) of the Q36 transistor to pin8 of the LM358 IC. Set the pot to maximum, power up and adjust VDD by measuring the output on pin2 of LM358. Both Q36 and LM358 are easy to locate, both are near the southbridge, on the PCI slots side. Using a ~17K fixed resistor gave me a ~0.2V boost on the VDD.
Soldering:
Voltages with the 17K resistor:
Hope this compensates for the clarity of the first pic:
Higher quality pics, thanks to cetoole from Xtremesystems.org:
Se qualcuno che smanetta coi saldatori vuole provare...
Io sarei molto tentato se tra 10gg non vendessi il pc
Thanks Micutzu

P.S.=Il link esatto da dove l'ho riportata e' questo
