so that would void the warranty?
No, it won't.
So I'm ok to change it with Rivatuner? One question, once I change it in Rivatuner, I don't have to keep changing it everytime I turn the computer on right?
Lol I know, sorry I had a brain lapse there -.-
Just click 'Save', 'Start With Windows' and 'Apply at Startup' or something along those lines. Then it'll do it every time you boot.
Heh, it's cool. No worries!
