Can't get stable with FSB increase

I usually run at 100x10 but I have been trying to get my FSB up. I tried 9.5x100 w/ a FSB=105.

It starts up and runs for a while but will freeze, usually within 10 minutes. I've tried adjusting the voltage up to 1.825 and also the i/o up to 3.6.

Nothing seems to make it stable.

Ideas?

Moved post to "AMD" motherboards.

Do you have cards on the bus that may not work well with the higher speeds?
Also the KT133 chipsets don't seem to like higher buses. I was never able to get my 133 set past 106.
Now im overclocking with a KT133a board, and I am at 150fsb.

For cards I've got: 3Com NIC, Vodoo 3500, SBLive. That's it.

Wife would shoot me if I "needed" another board.
