Klamath core CPU multiplier 2.0x with functional L2 cache should be like this:

1-2-3-4
ON-off-off-ON
or
ON-off-off-off

Sometimes you get a non-booting combination and in some cases an unintended overclock (though Klamath core maxes out at 5.0x AFAIK). Which is solved by changing the setting and rebooting again. I never managed to break anything with the multiplier dipswitches on slot 1 boards.

Hello! Please let me know if there a way to get 2.0x multiplier under GA686BX (similar board as the OP, but BX) and downclocking a P2 266MHz. Thanks!!

Actually haven't bought this board yet. Found this one locally with a seller and was unable to find much details on whether it could be made to support 2x. Thought of researching more on it before making the purchase.
