Have a old Gigabyte board here that is version 1.1 of the BX2000 (not the
plus version). Reading the installation guides, it says that you can set
the dip switches up to 133 MHz and 9.5x multiplier and that equates to a
1.26 GHz Slot 1 Pentium. However, they say it will only take up to a 650
MHz CPU.

What was the fastest Slot 1 Pentium Intel made? And does the 133 MHz and
higher multipliers actually work on the board, or was it just there for
marketing purposes cause they never thought things could go that fast in the
future?

Any hints or suggestions to getting which version of the fastest Pentium CPU
to run on this board? So far the fastest slot 1 CPU I've seen is a 1 GHz.

Thanks
