X1900Xt overclocking

[WaTaGuMp]

I am curious if Ati Tool needs to be open and running to have the card stay overclocked. Even if I close it the CCC still lists the card as running the overclocked settings. I have it hidden of course but the temp still shows in my taskbar near the clock. Its just something I am curious about since I didnt see anything saying if it needs to stay running or not. Also is there anything out there that can overclock the cards without making profiles and loading them etc, just something that you set it and forget it type of deal and also not stay running. I would also need it to be bale to up the voltage of course, you dont have to mention Ati Tray Tools I know about that one so any others I can take a look at.
