    I would like to downvolt my Turion ml-32 from default value of 1.0volt. I tried using rmclock but even at 0,975 volts the lappy freezes and hangs.
    Is there someone that has been able to keep ml-32 undervolt at least at 0.925 rock solid?

    what version of RMclock are you using. If 1.8 make sure you have the Power Scheme set to Always on. If you use 2.05, set the scheme to RMclock.
    you should be able to get to 0.975 at 4x with Ml32. I have my ML-34 at 0.925v solid for 8 months now.

    Hi Vassil.
    I use rmclock 2.05 and I set o.975 at 4x. Setting 0,950 the system hangs.

    I would like to set 0,925 me too :( :(

    What's for 9x?
    It's stable only at 1.475.
    The scheme Power on demand is not stable with my ml32.

    I was able to undervolt an ML-32 in the DV5000z to 1.1v at 9x and .85v at 4x.
    That being said, not all chips will undervolt to the same level.

    A second question. Is this a brand new machine or an older one? The newer chips probably have better tolerances than the older ones. Also note that I did a 24 hour "burn-in" period. I did the undervolting after words gradually and allowed the laptop to stay at each new level for three hours or so. This was done by running Prime95 at 100% load as described on a how to site.

    It's possible to go lower, but also note it isn't guaranteed.

    Mike

    Hm, it's a bit hard to believe that the ml-32 won't go under 0.975; possible but strange. Did you follow the guide from the undervolting thread (undervolting l2000)?
    When you set the multiplier make sure you have only one multiplier in the list, that is 4x, the Windows power scheme is set to always on and RMclock is set to Mininal.
    Some people, me included, have reported problems with version 2.05. I went back to 1.8 because i experienced occasional hangs with the newer one.

    You are right Vassil,
    I set as you told me.
    It's rock solid at 0,950v and stopped at 4x. The multiplier doesn't switch from 4x.
    :) :) :)

    0,925 hangs. At 0,950 and always on 4x the fan starts less. :)
