    When i check the MHZ it only goes down to 1600... that seems high.

    My mobile AMD 64 X2 1.8ghz goes down to 700mhz.

    Is this normal ?


    Thanks.

    I think the CPUs overclock a little on demand.

    BTW cpu-z does show the cpu at 800mhz... but pc-wizard still shows it at 1600... how weird is that.

    SiS Sandra shows that my T61 bus is operating at 1400mhz, which I don't understand. There's even a warning against overclocking my system bus. I've done nothing to do that though.. maybe detection software has not caught up with Santa Rosa yet.

    CPU-Z should be correct. Most other programs are usually a little off. 800MHz is pretty good. Is it undervolting the CPU as well?

    Maybe one's showing one chip's speed, the other shows both chips' speeds added up?

    Hence 800 and 1600? I don't know, just a suggestion.

    CPU-Z shows my CPU clock speed is at about 800 MHz @ 0.85V. Then when I do something intensive, the CPU clock speed and voltage ramps up.

    Trust in CPU-Z. The other programs are probably not up to date for Santa Rosa chips. Although I do not understand why CPU-Z shows your T7300 running at 2.3 GHz, lowspeed. Lenovo would not factory overclock it (if they ever did) without explicitly saying so.
