I have had my system running stable at 2.5Ghz already.The only reason im holding back at the moment, is that theres a well known problem amounst abit motherboard owners regarding the cpu temperature sensor(It reads higher than actual temp). I need to get an external temp monitor before i start pushing it some more.Also im still new at OC'n i need to do more research aswell. i'd rather be on the safe side and wait till i get more info and the proper readings.
