Im trying to overclock my radeon 6870.The most core clock i can get it to with msi afterburner is 920, and a memory clock of 1070, and i mean thats the clock that lets me go the longest without bf3 locking.I dont know how to change the voltage, because afterburner doesnt give me the option.Please help

In Afterburner settings, you can unlock voltage changing, although be VERY careful with that, as GPUs are extremely sensitive to voltage changes.
