Notice taken. I was just to make sure about the side-effects of such tweakers, and i couldn't find a better place to ask. So, ThrottleStop to avoid from now on. MSi Afterburner, son using it just to watch framerates into games, without touching voltages/clocks etc. Closing words: I see that many people going and asking for help (regarding such issues as mine), at various "overclocking" forums, and also son's school friend "adviced" us to go and ask at one well know such website. But i didn't. Me, i prefer to search and ask for help from people that have the true knowledge about this and that, instead of some fancy tweak kings or world records overclockers and such. And i'm glad i stumbled up sysnative.
