    Hi ive got a HP TX2-1150 with an AMD Turion Ultra ZM-84 processor. Ive tested the programm (i have to mention that this is a great little programm) and it works very well. AMD Power Monitor displays 0,75V @ 575Mhz. The problem is, that there is absolutly no temperature difference between 0,8V and 0,75! (cpu getting in idle mode up to 50-55 degrees) Is there an chance to get it lower than 0,75V? My notebook is drivin me crazy!

    Greetings from Germany

    Unfortunately, other than running in power saver mode not much can be done to control the heat with regards to the CPU. 45 - 55C is prett much the normal idle temps for the tx2500/tx2z series.

    One more thing you could try is to set the GPU to in power saver mode. This should reduce the overall temp and fan noise in the system.

    Hello :)
    i have a tx2510; i have changed the thermal pad (with a good result), but i would like to downvolt the cpu on high frequency.
    But i use vista x64, is it possible?
    thank you!

    its possible, i think Mr. Systematic have made a 64-bit version of the undervolting program earlier in this thread.

    Has anyone tried undervolting in windows 7 yet?

    I am using w7 64bit. I have used 49% and 99% processor plans instead of 50 and 100 respectively; combining them with undervolting, I am getting waaaay over 4 hours of battery life with 8cell battery.

    I never hear my fan (even though its set to always on in bios) and my laptop now doesnt turn my lap into barbecue.

    Thanks w7 and Mr. Systematic, I am now closer to being satisfied with my tx2500. Does this answer your question, that0n3guy?

    Hello =)

    i found this voltage stable :

    AMD Turion(tm) X2 Ultra Dual-Core Mobile ZM-80 (tx2510 hp)
    2100mhz 1.038 (VID 41)
    1050mhz 0.762 (VID 63)
    525mhz 0.75 (VID 64)

    I do not know how to adjust voltages below 0.75 Volt. This is a(n) (artificial) limit by the family 17 AMD CPUs. I can only guess AMD did this
    -because the voltage regulators the CPUs sends the Voltage IDentifier codes to can not provide less than 0.75 V or
    -to prevent to heavy undervolting

    Nice to see what your gains are, khael and others.

    I finally made (also for myself) the undervolting program as a service:
    http://amd.goexchange.de/ (my own website) because it annoyed me.
    Now an exe-to-service app is needed no more.
    This already works for ca. 6 weeks but I had to change some things (hard-coded pathes etc.) before I could release it to the public.
    If you have issues/problems with it: I can only spend 1 hour a day on average for it till about mid of June.
