LOL I am sure you mean Mhz not Ghz :¬)
2000+ is a 133 FSB chip. (12.5x133), you will need a LOWER not higher
multiplier if you want to try and run it with an FSB of 166Mhz. Just do the
maths on a calculator, take the rated speed or speed you want to try, divide
it by the FSB and that will (obviously) give you the multiplier. If the
value is not a standard value, you will need to pick one close to it that
is. Then multiply by the FSB to make sure you are not about to try a speed
that is truly ridiculous.
The value for a 2000+ with an FSB of 166Mhz but keeping the 'normal' speed
is 10.
