Problem With A 433 Mobile Celeron

[Pentium II Xeon 500 ES]

I have a notebook which uses a 433 moible celeron and a few programs see the processor as a 216 MHz. And it aslo sees it as having a 33 mhz bus when it is supposed to have a 66.

Why is it doing this?

Have you tried to use an older version of CPU-Z?
It's possible that the most recent version don't recognise this quite old CPU correctly.

Another possible reason of such strange behaviour is the energy saving features of your notebook. Most mobile systems try to save as much energy as possible to prolong the working time on batteries. If there is no work to be done - the CPU clock, VCore voltage and/or FSB frequency are reduced.

You should try to disable all of the energy saving settings in BIOS and Windows and run the CPU-Z again.

Taking FSB down below 50MHz is out of spec for Intel processors

If anything, CPu-Z is reading it correctly, or reading the wrong bus.

[Pentium II Xeon 500 ES]

Tried changing the energy saving settings and it did not help and bios does not support any of the energy saving options.

Windows task manager, cool beans, and a few other progorms that are designed to run on that processor say it is a 216.
