No currently released Pentium Pro products run at 333MHz.

It is generally possible to overclock Pentium Pros to 233MHz.

If the device is indeed a Pentium Pro, then there may be a bug in your 
BIOS.  Note that Pentium II processors are also identified as Pentium 
Pros, and these are available in 333MHz grades.  If you have a PII 
which your BIOS is claiming runs at 333MHz, but the boot-time 
calibration reports 233MHz, then you have either:

 - motherboard jumpers set incorrectly, confusing the BIOS.
 - a BIOS bug.
 - a motherboard bug.
 - faulty motherboard timekeeping hardware.
