Quick question about KT333 and XP chips

[Civic2oo1x]

I know that the newer XP chips will run at a 333FSB and the KT400 will have 333fsb. Will the 333fsb chips run on a AT7 or even my KR7A which is a KT266a? Thanks

I don't think ANY kt266a board have a 1/5 divider, and only some NOT ALL KT333 boards have a 1/5.
