When people say the voltage is 'locked' they just mean you can't increase it past 1.175v. Increasing the slider definitely has an effect, it seems to force the card to run at the maximum voltage (1.175) when the card is under very heavy load. When the voltage slider is left at default, the voltage just randomly reduces itself to 1.162v and i don't think anyone has really figured out why it does this. By increasing the slider, you can usually net a 10-30MHz increase in overclock. Some people are misinterpreting the locked voltage though. Because the voltage is locked, they go around saying things like, "changing the voltage slider won't do anything because it's locked," which is only half true at best. The voltage slider DOES help stabilize a higher overclock, but it won't let you get past 1.175v.
