My Sapphire 5770 1GB voltage is 1.125 so i cant overclock it to higher clocks. I flashed it with Asus unlocked Bios but after flashing its showing total black screen so i again flashed to original BIOS. I tried many BIOS XFX, asus and sapphire but everytime after flashing, its showing total black screen. Only original bios is working. What can i do unlock voltage. I flashed it with atiflash -p -f 0 asus.bin and after restart, its stuck at black screen on boot.
