I am limited with durons to 1Ghz and Athlons At 200Mzh to 1.2,As I have a Asus A7v Rev1.02 200FSb For some reason when I push a Duron (200fsb )over 1050Mhz they Crap up with the Blue Screen of P.C Death! But I could just unlock and straight clock an Athlon from 900 to 1200 just on clock speed! As for my four chips in under two years, when they blow they dont heat up like you think they would, they just go like a light globe, POP, on on second, gone the next, Always at Start up or shut down the system will hang, and bingo you know!! The last Duron I had was only fron 950 to 1000, cos of the blue screen probs, and it blew when I didn't shut down properly, was pissed and going to the pub on Friday night. Raced out, got all I could find was 900 Duron, Would love an Athlon 1.2 200fsb "unclocked" as I learn, If you can't afford another chip, don't touch it!!!!

or yeah, I got 1.08 Bios rev too, I know the board says it only goes to 1ghz but i have on board clock speeds (dip Switchs) to 12.5 and can wind fsb to 133, doesn't usually go much over about 111 before heat is to much, but that is about 1380mhz
