The highest I can seem to get my unlocked Duron 800MHz is 950MHz without using the FSB (last time I tried to overclock using the FSB with my Duron 600MHz, I ended up mysteriously ruining it).. If I try any higher, my screen'll go black as soon as I restart, then it'll be back at the default speed and voltage. It's a week 40 Duron 800MHz. Is this common or should I be easily achieving 1GHz with my processor?
