I have a Duron 800 on a FIC AZ-llE, I unlocked the processor using the pencil trick, but I can't get my processor to run stable over 800, Im at 850 now but when i try anything too hard on the processor the computer locks up.... I've tried different voltages and everything, but my processor was running at 874mhz with no problem without unlocking it....by the way this is in Win2k
