    I tried Notebook Hardware Control (Dell patch) with W7 and it works well.

    I only was not able to make it autostart. The .exe file is put by hand to the list of autostart programs, and it is visible in Winpatrol as such, but it does not autostart. It's a very minor issue.

    In comparison with XP W7 seems to require more memory (>400 MB vs > 250 MB) on my laptop, but the processor load is hardly higher. So, it is fine for my 1.1 GHz ultraportable with 2 GB of RAM.

    Ditto here. Rightmark CPU Clock Utility works perfectly.

    You can try to load NHC through the task scheduler, by setting it to load every start up or log in. That s how somebody suggested it in this forum. :D

    I tried undervolting in Windows 7 but I'm not seeing any drops in temperature at all. Went from 1.250V to 1.125V too.

    Same thing for me. I tried last night (from 1.1875V to 1.1125) and saw no noticeable drop in CPU temperature.

    If at all, a fix would need to come from RightMark, not Microsoft. Of course, as you point out, they're not likely to support a beta OS.

    Using RightMark on 64bit, Build 7000, working perfectly. Remember to obtain the RTCore64.sys driver which enables 64bit support.

    On 100% CPU load, I went from:
    1.2500v / 89 degrees...... to
    1.0375v / 72 degrees and stable.

    Windows 7 32bit Build 7260, Everest Ultimate (latest) shows voltage is not affected. And after awhile even RMClock shows different voltages than what I've set...

    Is there something to give your CPU less voltage that the RMclock minimum. I still idle at 50ish and ma out at 80s if it's really stressed. I've never had a single blue screen at .95 volts and want to go lower. Can I?

    The common answer is no, as it is the limit set by Intel for C2D (pre santa rosa) processors. I have the same problem with LV C2D L7400 which is stable at .95V on all clock levels but it can't be undervolted below it because of Intel's set limit.

    I would pay money to Intel that it would let us try undervolting below .95V for C2D, as it is a very annoying restriction.
