    hi, is there any alternative to cap the speed slower than 800mhz? My Pentium M runs at 1.6 or 800, i know XP comes with intergrated software similar to Intel's speedstep, but i am wondering if there's anything better.

    I saw SpeedswitchXP, but is a fairly old program, and i don't see any gain from it.

    If i can cap the CPU down to like maybe 300mhz, it'd be nice when i just use it for surfing.

    As far as I know, 800mhz is the lowest the PM will go...but you can decrease the voltage past what speedstep will do, using Centrino Hardware Control. The voltage is what really matters anyway...

    Sonoma uses second generation Dothan chips that run at 533MHz FSB... they go to 800MHz as their lowest speed.
    First generation Dothan chips run at 400 MHz FSB and run at 600 MHz minimum.

    I don't think you can run it at any lower than 800 MHz on your chip, codenamezero

    Thanks, Centrino Hardware Control works wonder, i am able to lower 0.3v across min and max setting. :) Which is like 30% less power, also made the CPU runs 3c cooler as well.

    I've actually seen my CPU speeds as low as 400Mhz when I goto System Properties (Right-click My Computer -> Properties). I've only seen this happen a few times, but I don't know what I did to get it this low. Possibly when my battery starts running low.

    When I'm on batteries, it's listed as if running at 200MHz sometimes, but it doesn't feel like it is, so maybe Windows reports it wrong.
