Two things can be causing your problem. One is that the motherboard used
by IBM in your system doesn't support CPU's >500 MHz. I'm not too sure
about what products are used in the aptiva line, so I cannot be sure
whether this is the case or not. The second possibility is that the bios
on the motherboard may need to be updated to be able to support CPU's >500
MHz. In either case you will probably have to contact IBM about whether
or the Motherboards they used in that model support >500 MHz CPU's and if
so where you could find a bios update for the motherboard.
Hope this helps,
