    (How well) does RMClock run on Windows 7 x64? In the undervolting topic in the hardware forum people seem to be having various problems, so I figured I should probably ask.

    Yes it works fine.

    I noticed Windows 7 is aggressive with power management and seems to take over RMclocks functions. So for best results try choosing RMclock as the Windows power profile. It will be under 'Additional Plans'

    Maybe its a good idea to change the Balanced, High Performance, and Power Saver to use the processor at 100% as well.

    I don't know under what conditions Windows would automatically change profiles except if you manually tell Windows to determine the WEI score it switches the plan to High Performance. Now Windows tries to control the processor speed rather than RMClock, if you undervolted you might get a bluescreen.

    I was referring to W7 cpu management taking over RMclocks. When i locked my CPU to the highest multiplier i noticed it was just clocking up and down until i changed the power plan to RMclock.

    Was there some trick to it? The first time I tried to fire up RMClock it immediately whined about the driver not being signed.

    I took a quick peek at the RMClock power profile, and a lot of things don't seem very power efficient. I'd like to bring it more in line with Balanced settings, but is there anything about the RMClock profile that I shouldn't touch?

    Rmclock profile is actually a custom profile to match the CPU management.

    Theres no need to disable unsigned driver. I have had the signed x64 RMclock driver for like a year now. See the undervolting guide

    Bah, Windows 7 is way too aggressive with power management when running on battery power.

    I could not stop the OS from fighting with RMClock over control of the CPU. On balanced, my voltages kept going up and down nonstop and on the RMClock plan, both my voltages and multiplier kept bouncing around :mad:

    Too bad the "elite energy saving abilities" results in losing ~10 mins of battery life compared to Vista.
