Hi all, I need help overclocking my GPU. Currently I am running my Sapphire HD 6770 at 1000 MHz and 1290 MHz memory. I set the voltage from 1.2 to 1.25 in Radeon BIOS editor. But AIDA 64 still shows that the voltage is 1.20. Although I can overclock much higher than previous. Also is there any way to increase the memory voltage of the card? The memory bandwidth is all this card lacks.
