    How does throttling work?

    My performance goes down the drain completely when on battery and it never made any sense because CPUZ would read that I'm running at full speed. Today I was looking at the RMclock monitoring while on battery and I noticed that even though the multiplier was as 11x and CPU core clock was 1830mhz, the "throttle" was much lower. (450 idle, ~800 load). I assume these are the ACTUAL CPU speeds that I'm getting on battery. How exactly does that work though? And why does CPUZ read an incorrect clock speed?

    I am a little confused..
    Could you post up two or three screenshots of CPU-z and RMClock together to demonstrate?

    throttling simply reduces the multiplier, CPU-Z might have trouble recognising this changing, unless it is changing the FSB

    Idle on battery. 453mhz? It certainly performs like 453mhz to because I've locked 1ghz on AC power and it is much faster.

    its quite toasty for only 1Ghz, considering that i have a 2.4Ghz and it runs in the 30's (T8300), the XPSM1210 is old, the temperature sensors may be broken
