I'm a little confused since I thought that the BX chipset allowed everything to run within spec with an FSB of 100MHz.
well I owned a tiger 100 and a tsunami. in the latest BIOS updates there were options to change the FSB, but there were only 2 or 3 settings between 100MHz and 133MHz. In my experience using these settings only slowed my system down, and I can't explain why. There was deffinitely no lockdown or divider function for PCI and/or AGP clocks.
my opinion of these boards is: nice and stable and fast (for what they are) but the built in floppy controllers burnt out on both of them.
