    In K10Stat, I can't seem raise the value for P-state 0's core frequency via the FID and DID options. For instance, P0 default is 2400x2400, CPU(V) 1.1125, with an FID of 8 and a DID or 0. Changing FID to 9 changes the frequency to 2500 on k10stat, but according to all my monitors, it drops down to ~1590 GHz in reality. Changing the value to 10, 11, 12, and so on, register 1590 GHz on the monitors despite saying 2600, 2700, or 2800. It is also the same with an FID value of 32 and a DID of 1, except an FID value of 33 drops the frequency down to ~800 GHz.

    Changing the FID below 8 and 32 will also reduce the frequency but in the smaller increments that I assume are normal.

    Now, when I change all the P-states to be at least 2400 GHz, changing one state to something like 2600 and enabling that state keeps the frequency at 2400.

    I have also been fooling around with TurionPowerControl, with the same effects, although when running the -L command, it states my computer has a max frequency of 2400.

    QUESTION: What is going on here? Isn't the increased FID value supposed to raise my CPU frequency? Shouldn't this all be able to raise the max cpu processor frequency beyond 2400?

    I also cannot raise the P-state CPU voltage above 1.1125V, however, I can change the North Bridge Voltage, but that is the same voltage (.9875V) for every state. I can change the CPU voltage in the "debug" tab but that has no effect.

    My processor is AMD Turion 2 P540.

    did you note that the NB only runs at full speed in FID0 and B0?
