The only values that the MB can control are the voltages and the Front Side
Bus (FSB) clock. If you choose to clock it higher than 66 on a Celeron II, then
you are pushing or overclocking it according to spec. However, since it based
on the P III coppermine core, you can probably reliably overclock the FSB to
100Mhz or more.

I don't recall what the proper core for the Cel-II is, it may be 1.5, running
it at 1.65 should not be a problem, again being based on a core whose default
voltage is 1.65. The fact that your mobo thinks it is a P-III menas it isn't
up to date to recognize Cel-II, there may be a flash update available, but it
will likely work just fine as-is.

I have two systems, one is an Abit BP-6 with dual Celeron 433's clocked to 548,
and the other is an MSI 694d with dual P-III 600's (not overclocked at this
time.) Both run Windows 2000.
