D/l msi Afterburner in the options select to use voltage control, also force constant voltage, raise the voltage on the slider to 1175mv ( that's the high end for the 7970 stock shipping voltage, it ranges from 1025mv-1175mv) , check and see if your card is stable, I would go as high as 1200 on the voltage to check stability, no problem for the card.
Also its possible the mem needs a little bump, found under the pull down tab on the Afterburner CP at the end of the core voltage control slider.
Bump your power limit % up to 20
