I had the option to enable it and disable it when i used to have an i3-3210. and i had enabled it but now i use and i5-2500 and since then i can't find those option in my motherboard. I want to enable it because it helps my pc to work better at games .i don't know why but it does. Can anyone figure it out how can i enable that and disable c3/c6 state in the Gigabyte h61m-s motherboard.
