[melikepie]

I've tried to overvolt my 6870 but it wont work! What program will allow me to do this? Im trying to get it to maybe 1.1GHz. (what volatge do u recomend?)

There is absolutely no way HD 6870 will ever reach 1.1 GHz core clock. No-way. I wouldn't count you will succeed over 975 MHz.

However, if you still want to play with voltages, you need to go to MSI afterburner settings and check the unlock voltage control box:

I did that and it's still locked. Why can't it go past a 75MHz OC?
