I have a Dell Latitude X1 that has a 1.1ghz ULV Pentium M processor. The Speedstep on this processor is supposed to jump between 600mhz and 1100mhz by modifying the multiplier between 6x and 11x.
However, now I'm starting to get speeds such as 330mhz and 460mhz. The processor is not supposed to ever Speedstep to such a low speed. I checked with CPU-Z and it seems like the processor is dropping the FSB from 100mhz to random lower values such at 52mhz and such.
Does anyone know why the processor keeps dropping the FSB below what its supposed to? Technically the FSB should always stay at 100mhz and only the multiplier changes during Speedstep.
