If you have a MSI card, you need to adjust it, then go to your MSI Clock info thing, then press apply on the clock things, it kept reverting for me too, but I ahve it sorted out now...
6800 CANNOT have thier piplines unlocked. It can only be done on a few cards. But if you are talking about OVERCLOCKING please run through my thread on how to use coolbits
EDIT: Now ive actually read the thread... There is an option in riva tuner which says "keep these settings on start up" I had the same problem and this solved it
Yeah, I was going to say something about that 99nasha, but, lol, you got that covered. Yeah, ati is a different story, but, rather, nvidia continues where the 6800 cannot unlock.
