    I have tested the "sticky" setting 6 times now with the "Rest Button" app and it sticks everytime. When I got up this morning my Prestreset had started and launched the Govnah, but it did not go to my Normal setting it went to "unknown profile" conservative. However, I just had PrestReset do a reset and it did stick with my regular profile. I have been able to reproduce the starting of Gonah with PresetReset another half dozen times. The combo of PresetRest and Govnah/Uberkernel is AWSOME!!!!!! This is VERY exciting!!!!

    1) Min is 500 for screenstate

    2) If you use the userspace governor, then LunaSysMgr will overwrite your settings. With performance, it does not.

    Where did you get a limit of 45C from?

    A stock Pre goes over 45 just playing a 3D game ...

    I got the 45C from general reading on the OMAP series, and general guidance on maintaining stability and longtivity of a cpu. 45 is also my personal preference and is what I feel comfortable with. Would you mind if I ask your recommendation?

    Personally I have never popped over 45 on the cpu temp while playing 3d's games.

    I'd be interested in any references you have which provide guidance from the manufacturer on this topic. I've not been able to find anything other than the 0 to 90 degrees absolute maximum rating in the OMAP3530 electrical specs.

    If you load the CPU at 600MHz, you can get the internal CPU temperature to go over 50C without a problem. Different games will load the CPU differently, and it will depend on what other things are happening in the background.

    ssh-keygen is a good command-line way to load the CPU.

    Certainly when I'm back at my computer I will try to dig up the articles that I read, I'm not trying to kid anyone around. Out of interest could you please point me to what you have read?
    And I will run that command when I get a chance and see what I get.

    Run three of them in parallel to get a sustained 100% CPU utilisation.

    The OMAP3530 electrical specs are at http://focus.ti.com/lit/ds/symlink/omap3530.pdf (see section 3.3 on page 123).

    You can only get OMAP3430 specs under NDA, but Wikipedia says it's the same chip just marketed differently.

    when using 0.4.1 and i choose fixed speed 800 and close govnah and open it again, it'll show the profile as "Unknown"

    Thanks, I can reproduce that.

    Switch to another card and then switch back again, and it shows the right profile. It's something to do with the startup-assistant that I added.

    Had my first overnight PresetReset with the sticky Govnah and it worked exactly as it is suposed to for me. Had the PresetReset launch Govnah and when I checked, it had my normal profile with settings launched. This is one very happy camper!

    i just installed preware and govnah with the uber kernel for the first time today so bear with me

    after reading everything it seemed the "ondemand" was the best cpu scaler, but it just makes my pre sluggish

    if I keep it on screenstate its fast but it only scales to 500mhz when the pre screen goes blank

    am I missing something or is there a better scaling profile? I dont mind screenstate but Id like it to drop to lower than 500mhz when idling. maybe the conservative governor?

    Did you reboot your phone after installation? You should be able to choose up to 800Mhz.
    Screenstate works best for me so far.

    I've had problems with ondemand...try conservative with "freq step" set to 100%.

    Ondemand works fine for me:

    -min 500MHz
    -max 720MHz
    -sampling rate 0.2s
    -up threshold 70%
    -ignore nice load: false
    -powersave bias: 1

    Hope that helps

    i may have worded it wrong, but I was referring to it only downclocks to 500mhz when the screen is off. Id like it to go lower.

    I'll toy around with it and try these settings later

    I've been overclocking PCs for years and the target temperature for CPUs for as long as I've been overclocking has been 50C. And considering that the maximum temperature of both CPUs is 90C I would expect the target temperature would be the same. There is only need for concern when the CPU temperature is getting close to the maximum temperature. The farther away from 50C the temperature increases the more likely there are to be stability problems so one probably wouldn't want say 65C up temperatures but 55C and even 60C are fine if the device is stable. Voltage has more of an effect on lifespan than the temperature. But really if you run the math the device will likely be replaced long before the CPU fails from exceeded lifespan even under overclocked conditions. I've had PC CPUs overclocked for 5 year with 35-40% voltage increase and still running. The only thing I have ever had fail on me in the past is a CPU heatsink fan after about 3 years of 24/7 running.

    I've found my Pre can't go under 500MHz after being playing ondemand 500-720MHz for some days... but after rebooting it it again accepts going under 500MHz (despite I prefer ondemand 500-720)...

    Can you try to set ondemand/conservative 250-720, for instance, after a reboot and see if it works?

    General question guys. I'm really looking for a way to improve battery life in a poor signal area, short of putting the phone into airplane mode (which doesn't work because I need to be able to receive the occasional texts.)

    Would this app help? If so, what would be the best setting? Right now the phone goes hyper while off...trying to hook up with the weak towers constantly.

    Rod, sorry for taking my time, have only now got back to my computer.
    Anyway, my searches in the last half hour have really only yielded me a bad head. Anything that I found that mentioned the 45C were based more on opinion and speculation rather than fact.
    I admit that my recommendations are over-zealous. But as a end user I still maintain 45C to be my personal comfort level for my device.
    If you would like me to restate some of my original comment let me know.

    No problem - I think each individual will get a feel for their own personal comfort level over time.

    And we shouldn't forget that the CPU is not the only device on the board, so excessive heat will affect other components too. However, the heat from a charging battery and a well-used cellular connection is likely to swamp that from a fully-loaded CPU.
