Cant seem to overclock my card

I ve been trying and trying but everytime i set my mhz. it always goes back to the default frequency. Any idea why?

What are you using to overclock?

Your card is probably locked. Google around for a way to unlock it. Its pretty easy to unlock I think.

how do i unlock my card? i searched google but cant seem to find it

They can't be locked. Certain cards have disabled pipelines, of which the process of re-enabling is often referred to as "unlocking", but other than that no.

It is not locked, what program are you using?

I wouldn't be surprised if you are forgetting to apply the settings, or save them so it saves the settings on startup.

i am using river tuner and i set it as start up with the overclocked value but when i restart it. the speed is still same

Did you check the box that enables the moving of the sliders?

yea and i changed the frequency from there but it doesn't seem to do anything...

It will always go back to defaults once you log out of windows unless you have saved the settings you change and then check the box that says startup with windows. You also might want to try starting up riva tuner itself via registry Key that could do it. I have never had the problem your having using riva tuner. if you have everything marked and checked and all then I would just take the time to delete my drivers and rivatuner and install all of it new and see what happens.
