    50ohm VR from pin #9 to ground should do it (edit: should maybe add, on the VT1165MF IC and one on each since there's one for each gpu)

    Just need a more convenient solderingpoint so if someone with cards laying around would check for that, preferably on the backside of the card.

    not the best pictures

    Excuse the quality but I'm not a very good photographer...I'm also not sure if I captured the right areas of the card, so let me know and I will try to get what is needed. I just hope these can help someone out.





    EDIT: removed the cruddy images....
