Let me rephrase the above statement since it appears I was not very clear the
first time.

Yes the only way to overclock the Celeron is to change the Front side Bus to
100MHz. This is not really overclocking the bus since the bus is rated and
supports 100MHz, what is being overclocked is the CPU.

Not really if the RAM is rated PC-100.

No concern at all if it's PC-100, doesn't have to be an exotic brand or spec.

This exercise is a lot simpler than taking a 233MMX chip to 250MHz with an HX
chipset based board, where the bus was overclocked to 83MHz, and the PCI to
41.5MHz. Here you needed good RAM, video card, and drives to tolerate the higher
speed. Cooling was an issue since everything was creating abnormal heat running
higher than it's rated speed.

Taking the Celeron to 504MHz might be a bit more interesting. Then again a mere
12MHz is no sweat for most of today's RAM, and 3.9MHz is nothing for the PCI to
worry about. Cooling may not even be that big of an issue providing the voltage
is not too high.

With the Celeron I feel the weight falls on the CPU, not so much on the rest of
the components, except for the mainboard, as always, that's got to be top notch.
