7AIA0 with Athlon??

Is anyone running a 7AIA0 with and Athlon chip. I have one of the first
releases of this board (its only a 66ATA version) and only supports 100Mhz
FSB. Out of the box this board is suppose to support Althons to 1200mhz.
However it wont run stable with many freezes and board not rebooting after
saving bios changes etc. The board works flawlessly with a 600 duron. I
have tried various bios updates and none seem to solve problem. I am trying
to run a 1000 Mhz Athlon (100 x 10).

Any help would be greatly appreciated.
