There is a setting for 133MHz fsb on this Mb... But will it work with a Athlon C?

Can't seem to get it to work with my 1GHz (100MHz) Athlon... My memory can handle it, but i doubt it would boot at 10x133= 1333MHz even at 1.85v...

this won't post at 7.5x133=1000MHz.
I know why, but read this if you don't : http://www.anandtech.com/showdoc.html?i=1440&p=2

Will me getting a 1333MHz (266MHz fsb)even work on the A7V? (NOT A7V133!)
