    This morning I was extensively using Youtube, radiotime, and doing some web browsing.. Pretty heavy usage, I was specifically watching the CPU temp as I wanted to know what the normal full load temp is with my specific Pre.

    Here are my findings:
    idle userspace at 800Mhz my temp was low as 20C!
    under high load userspace at 500Mhz or 800Mhz my high temp was 54C but was generally around 50C

    Basically it really seemed like no matter what frequency I was running, my Pre's CPU max temp was not impacted.

    I was thinking it could be useful if we had some sort of stress testing application like Prime95 for windows.. To purposely tax the CPU to 100% load. When overclocking PCs this is an invaluable tool.

    Maybe it was under 20c? I don't really remember what the temp was, but I do remember the temp not showing up below a certain number

    I actually just saw mine at 18C just as I came out of idle. So ya. *shrug*

    Well I think the only reasonable thing to do is put our Pres in the refrigerator and see if they still register a temperature!

    (you kidding of course, that probably is not a good idea, lol)

    You are probably right about a minimum measurable temperature though. I think some of Intel's and AMD's processors only measure temperatures with a certain range , like from 50c to the max operating temperature of the CPU.

    Rod, thank you for releasing the official 1.4.1 kernel. After putting that down I was successful in installing Uber-Kernel w/ Govnah. I'm now flying with the Performance setting at 800/250

    I tried these settings without luck. My screen flickered during video playback. Phone locked up when trying to run Super KO Boxing. I was monitoring temp and it seemed to run steady around 38C.

    I was running ondemand with the stock settings quite nicely. No lockups or anything and scaling down to 125. however after letting it sit for a while getting great battery i checked the govnah and noticed it not scaling down past 500. i did what i did to get it unstuck the last time which was to use uerscaler and scaled from 125-800 and then restarted it. reset ondemand and it is once again scaling correctly. Next time i will try without the uberkernal step and see if it works.
    Thanks again for all your hard work.

    Have you tried conservative with the same settings?

    I think video playback doesn't like ondemand's sudden changes in frequency. Conservative would flicker on mine but not during actual playback.

    It seems to not working Superkernel Govnah. I uninstalled the Superkernel and I installed the Uber-Kernel but I do not work. Someone can tell me all the steps to install the Uberkernel and Govnah . What are feeds to be installed and in what order? Thank you very much

    Govnah (and the kernel) will measure and report temperatures down to -40, but we've only created icons for down to 15 ...

    Well it def will not stay with a setting lower than 500 for me on demand. It will until i close govnah and the screen shuts off. the next time i go to check it, it wont go below 500. i changed the up threshold to 40% too and i dont have any issues with playing videos.

    The SuperPreKernel contains a webOS 1.4.0 kernel binary that Marco (who now works on the stable WebOS Internals Uber-Kernel and the latest bleeding-edge compcache kernel) developed back in March (check "cat /proc/version" when running that kernel for the exact date). That kernel binary has been repackaged many times by the current SuperPreKernel developers in many different ways since then, and the latest repackaging of that unchanged webOS 1.4.0 kernel binary from March is in the latest SuperPreKernel.

    It does not contain the latest available kernel features like the internal CPU temperature sensor or the conservative or performance governors.

    You should contact the maintainers of the SuperPreKernel for instructions on how to uninstall it. Instructions for installing the Uber-Kernel can be found earlier in this thread. You need to reboot the Pre after installing the Uber-Kernel.

    If you've set your up_threshold to 40%, then the CPU only has to be @ 40% in use to scale up, and if you're running Govnah with graphing details, it's most likely (especially with the ondemand governor) that CPU usage will increase to around 500MHz while you're checking it.

    Personally I don't see the point @ 125 or 250 speeds, if battery is what you're concerned out, the biggest problem are the phone radios. Pre @ 250 is inoperable for me, in a pleasant way I mean. Min I tend to scale to is 500

    I had many issues with that, but I was wrong because x amount of people had no issues and was made to feel like an ashole

    --edit--

    Besides a little bump in the beginning I have been running the Uber-Kernel now for a week with zero issues and I am loving it!!!

    but what are all steps to install the Kernel Uber? First installed a feed? What is this feed? I do not know how to install it. Thank you very much

    Adding Custom Feeds - webOS Internals wiki

    You'll need to add the one ending in 'all' and the one ending in 'arm7'

    yeah i know what you mean. i didnt change the up until after i realized 125 wasnt sticking. when i first got it to scale down i actually did catch 125 in govnah. but your right. i was using the old kernal scaled between 500-800 and besides the problem i liked the response. i think with uberscaler it is set to like 10% up. might even try going a little lower than 40 and see how it reacts. Love this stuff. im such a noob to all this stuff but i cant get enough right now.

    This is correct to install Uber Kernel?

    1) Add all the feeds ending in "all" and all the feeds ending in "ARM7"
    2) Restart the phone with Luna
    3) I install the Uber kernel with Preware or Preware Alfa
    4) Restart the phone with Luna
    5) I installed Govnah with WebOSQuickInstall
    6) Restart the phone with Luna

    need to do anything else?

    thanks

    1) http://install.preware.org
    2) Testing Feeds - WebOS Internals
    3) Install Uber-Kernel and Govnah using Preware
    4) Reboot

    Yeah that's what I meant, I was in the middle of messing with my down threshold and trying to get the phone to pop down quicker too, and said it backwards

    I lowered my up threshold to 75% and raised the freq. step to 20% with the conservative governor and am seeing improved performance without a noticeable reduction in battery life (during the brief, preliminary testing I did today.)
