High Performace option in bios Ga7vac

What does it do ? It does not work on my sys! Why is that?

Never worked on mine either. I think its some kind of of default GigaByte o/c. I did it manually and it worked better anyway.

it changes somethin to do with the ram. If u hit CTRL+F1 i think it is (been along time since i been in the bios) it gives an extra option where by u can change the ram timings. Try setting them to the slowest speed (highest settings) and apply the High performance setting. I have heard that it works then, but im not sure exactly what it does. Have a fiddle, thats how my gigabyte motherboard died no worries another 1 is on its way under warranty
