Overclocking in Afterburner

[KingOtaku]

I recently bought a R6950 Twin Frozr III, and begin overclocking in MSI Afterburner. My problem is that it limits the OC to no further than 900/1350. I would like to unlock this so that I can OC my card further. I have tried going in the cfg file and editing it, but whenever I try to save it in notepad, it just says "Access is Denied" Does anyone know how to fix this?

Sapphire TRIXX, try this instead.

Can I ask one more question though?
I'm using MSI Afterburner to change the voltage, but even when I change the voltage slider, it doesn't work. It's stuck on 1.15v. How do I fix this?

Just cut and paste the cfg file to your desktop,make the changes then copy it back.

Thankyou, that worked, but i still cant control my voltage. Even if I unlock voltage control and move the slider, it doesnt change the voltage. How do I fix this?

Are you sure your card can make use of voltage changes? Here's a link that might help.

hmm....The picture is a bit hard to follow, do you think you might be able to clarify a bit?

Wait, I managed to follow the instructions correctly, but it didn't work :/

Oh, thanks henydiah, I already had that page saved to my favorites
I decided I wouldn't attempt an unlock until I absolutely needed to, as I don't want to take the risk, since there isn't any dual bios switch.
