i currently cannot increase my clock using bios, dont know why, i already flashed it with the bios that have higher clock, but nothing happens. I tried using GPU-Z to retrieve the bios and it is the changed bios, but i wonder why the clock speed never change. And the Overdrive cannot be closed or lock back edi.
