Yes it's possible that both are valid. If your processor and motherboard
both support the 133 FSB, then use the 9x133. Especially if your ram is
PC133 or DDR. This will actually make the machine slightly faster because
the data will be moving around alot faster than it would with a 100 FSB.

As an added benefit of running at the 133 FSB and a lower multiplier, the
chip shouldn't have to work as hard and should be marginally cooler IIRC.

I doubt your starving the processor for power unless you're overclocking,
in which case your processor would run extremely hot. I haven't been a big
fan of overclocking since I ran my k5-75 as a k5-90 under 'doze.
