Hello, I started using afterburner about a month ago I have a Geforce gtx 460M on an alienware M15x using Windows 7 Ultimate I installed afterburner and could increase the Core and Shader clock with it I start to tested with different games and it made a lot of difference. Now after a month I started to feel the games like it was before and I realize that the overclock was not working it get back to the original settings. Now when I try to overclock and apply the settings again it does not allow me to do it. I tried to install and re-install the software and the same I cant overclock I tried to activate the UnofficialOverclockingMode and nothing I cant apply the overclock settings like before any ideas why this would happend? working for some time and now it doesnt. thanks.
