Say just asking--i know this is old stuff--but i got a 2500 barton--and bought a new epox 8rda3+pro mobo--just got everything dirt cheap and thought i would play around with it. Problem is--i cant get this thing to over clock worth ****. can only get 11x200 at 2.00 volts and then only run for a while--the barton chip checks out and the mother board does too. also--cant chang the clock speed in the bios--i can set it to higher --but it wont register above the default of 11---this same chip will change on other boards--epox says there is nothing wrong either. just an old question to who may have an answer--i have over clocked many times--but this has me stumped on what the prob is.
How are you cooling? I have a 3200+ barton and they run pretty hot. I remember hearing that you could run a 2500+ at 3200+ speeds (2.2GHz I think) so your 11x200 sounds about right.
Do some googling.. stuff like
