Hi, Ive been doing some research on how to unlock my Sapphire hd6950 cards and ive found the very useful guide here http://www.techpowerup.com/articles/overclocking/vidcard/159 however I then found this http://forums.guru3d.com/showthread.php?t=350307 Which is considerably more complicated. Im not sure which method I should follow, has anyone had experience with doing this with the sapphire cards and how to do it? In addition, I have 2 of these cards in crossfire and have no idea how either method would be used to unlock them both. If anyone knows how to do this that would help a lot. Thanks.
