My 1.6 duron will only go 1.2

[FastTruck]

I have a azza kt3-av motherboard. I updated the bios to a bios dated 1-9-04. I have an amd duron 1.6. My motherboard will only recognize 1.2mhz. It is set at 100fsb on the mb with the jumper. Is there a way to find out what the limitations of this board. If i set the board to 133fsb it will not boot up. Please help.

If its an older chipset, it may have the option of 133 FSB but not be able to actually do it. That happened to me on a kle-133 chipset. Best I could get was 110 even though there was a jumper setting for 133. I could not run any athlon XP's or morgan/appalbred Durons on it though, only Tbirds and spitfire Durons.
