[Atrix 4G Android Development] chronicfathead:
I've flashed the 1GHz 024 r2 kernel, and I'm noticing that it's not really dropping down to the lowest frequency. If I open SetCPU and look at time in state, I seem to have spent 70% at 312MHz and only 1.6% at 216MHz.

I have a profile set to 216 with the screen off, but it doesn't seem to settle. If I watch the main screen in SetCPU my frequency is jumping all over, but when I've run other kernels, and even older faux kernels, they seem to settle down at 216, even with the screen on.

It was fine on Clemsyns 1.6GHz kernel before, but after flashing the faux 1.0 024r2 kernel I'm having issues.
[Atrix 4G Android Development] Ilkinansr92:
Yeh i have the same thing my stays 16% @ 216 and 47% @ 312

Also been lookin at SetCPU and it doesnt seem to stay at same frequency for long just keeps jumping unlike on 0.2.3
[Atrix 4G Android Development] fleurdelisxliv:
Im showing 30% at the lowest 216
[Atrix 4G Android Development] MyronJ906:
I wanted to say that I'm having this exact same experience. Just watching mine and doing nothing, I get it literally circling through all of the frequencies as if it is bored or something.
[Atrix 4G Android Development] guidoido004:
I think it is a setcpu problem, im using pimpmycpu and it doesnt do that.
[Atrix 4G Android Development] sk8trix:
I do see the frequecies jumping but i dont know if it really affects anything since flashing the kernel this afternoon my battery life is acting the same as with anything before......maybe it is setcpu acting stupid....will try uninstalling and installing again and check if that fixes it at all
[Atrix 4G Android Development] guidoido004:
My setcpu actually works finee, maybe this is just an issue of the frequency showed
[Atrix 4G Android Development] sk8trix:
probably because i just re installed as well and now it seems more stable but still jumpy but now its ranging from 216 to 650 ish but not jumping all over the map and the time instate shows that when screen is off my profile is sticking....
[Atrix 4G Android Development] cmoG530:
Been having random freezes and reboots since I flashed the 1st rc. I'm switching to clemsyns 1.0 just to make sure it's not a rom issue.

[Atrix 4G Android Development] sambaeallegria:
With latest weekly CM7 running the 1.0 GHz 0.24r2 I had 2-3 random reboots per hour. In particular I noticed reboots tryng to unlock the screen or straight after.
[Atrix 4G Android Development] guidoido004:
Undervolted? This may be the problem.
[Atrix 4G Android Development] sambaeallegria:
I thought the same. I undervolted with the same values posted by fleurdelisxliv. Maybe I have to undervolt with other values but what are the minimum values for 1.0 version?

I mean, CM7 kernel is set to some values, that I can't see, and these values let the phone work properly. Can I use the same values for faux? If yes,what are these ones? 'cause i want to let the phone work with minimum overvolt.

Yes I know,maybe it's a noob question and you can answer me: "You have to found your personal settings" but I know it's never easy.
[Atrix 4G Android Development] guidoido004:
The defaults from faux123 is the stock values, undervolt doenst work with everybody, sorry.

[Atrix 4G Android Development] guidoido004:
No, the kernel is stock volted, you cant overvolt, only undervolt, but if you want so badly to undervolt, try values.... its the only thing you can do to see which values will work...

Mmh,some time ago I read that faux's kernel was overvolted by default,maybe i'm confusing it with the Clemsyn's one or the eternity project's kernel.

Please, post your values@freq and which app have used to undervolt?
[Atrix 4G Android Development] sambaeallegria:
These are my values:

950mv -50 =900mv

900mv -100 =800mv

775mv -275 =500mv

750mv -350 =400mv

I used SetCpu.
[Atrix 4G Android Development] Swiftks:
For the 100th time, you can not use other people's values and just expect it to work.... you should go frequency by frequency on your own, and test your undervomt limits, as every device is different.
[Atrix 4G Android Development] fleurdelisxliv:
swift is right whats good for one phone may not be good for another! i guess you can look at other users uv's to get a base to start but you should def try it out till you find what is best for your phone.also i blve you should not set at boot until you find what works best :)
[Atrix 4G Android Development] sambaeallegria:
Yes I know. Thanks you for your help, I'll try later :)
[Atrix 4G Android Development] sk8trix:
I keep reading that undervolting makes the phone get warmer and even though battery lasts longer it bring performance down a little can anyone please put it in clear words??

I have undervolted before but didnt really notice much,I also didnt go over 75 on each step idk if its even worth it.

I do get about 10 hours at 1.45 without undervolting
[Atrix 4G Android Development] Maringer:
Undervolting does not make your phone get warmer. Successful undervolt should, if anything, make your phone run cooler as the CPU is drawing less power.

Undervolting does not reduce your phone's performance at any given clockspeed, either. However, you will struggle to run the various overclock speeds over 1GHz if you undervolt too much.

In theory, you should be able to gain a reasonable amount of battery life by undervolting. However, it really depends how you use your phone. If your general usage has the screen on a lot, it isn't likely to make all that much difference. Also, as you are running the CPU 45% faster than stock clock speeds, don't expect too much of a miracle!

Personally, I think it is worth taking the time to work out how low your phone can undervolt at the various clock speeds and then bump up the voltages by 25 or 50mV all around to ensure stability. The problem with this, of course, is that when trying out new voltages and ROMs, it is never clear if reboots are caused by too much UV, bugs in the ROM or bugs in your apps!
[Atrix 4G Android Development] sk8trix:
Yea I mainly consider the reboot issue but i guess I will try undervolting again and see if I get different results this time around.
[Atrix 4G Android Development] Maringer:
The thing to remember is to test each clock/voltage for a long time. I'm talking an hour here. Run a continuous torture test of some sort with the clock speeds and UV set at a certain level. If it passes these tests without problems, try dropping the voltage another level and run again. When you've reached your final limit for each clock, I'd move the UV up to the previous level and run for a few hours if possible just to be certain.

As you may guess, this is a rather time-consuming process which is made even trickier by the -100mV gap limitation between clock steppings on the Tegra 2!

Therefore, I'd start your testing at the maximum clock speed you wish to use and make sure your maximum undervolt there is super stable before trying to test the next lowest clock step.

A UV error at the fastest clock speed may nullify all your UVs at lower speeds!
[Atrix 4G Android Development] paravorheim:
I just found this on xda's homepage:

http://www.xda-developers.com/andro...ry-study-brings-about-surprising-conclusions/

Apparently, undervolting on nexus s kernels did not increase battery life. I would expect different since lowering voltage should reduce the amount of current needed, but the evidence is there.
[Atrix 4G Android Development] faux123:
Different architecture different phone. Tegra2 DVFS is really a hardware solution and is quite nice compare to other architectures.
[Atrix 4G Android Development] Maringer:
Not sure what the situation there is but, by definition, undervolting can't fail to reduce power draw. It's the laws of physics! ;)

Comparitively, reducing the operating voltage actually reduces power draw much more than reducing the clock speed. The formula in the following link illustrates this:

http://en.wikipedia.org/wiki/Dynamic_voltage_scaling#Power

Several years ago, I built a (relatively low-end) HTPC and I was able to more than halve the CPU's power draw by undervolting alone. Believe me, undervolting works!

Power savings of this magnitude aren't available on phones, however, as the CPU isn't necessarily causing the vast majority of the power drain the way it is in a desktop PC. In a phone, you also have the screen, baseband, wireless connections etc etc. all drawing power when in use. Therefore, undervolting your phone's CPU can help to some degree, but it isn't likely to make a massive difference in battery life.
[Atrix 4G Android Development] paravorheim:
Okay, so as I understand it (I'm still trying to figure this stuff out) dvfs is a feature that is fairly standard, but by having a hardware solution to this you can bypass the software? I feel like I'm completely off, but if that is the case, then does this mean that the implementation of UV on the nexus kernels must be incorrect somewhere?

I'd love to know more about this, so if you're willing I'd love to hear your explanation.

P.s. I see the thread name isn't updated to account for your newest release.

---------- Post added at 06:22 PM ---------- Previous post was at 06:18 PM ----------

I completely understand what you're saying. Maybe I should take a look at the actual data from the nexus s battery tests. Also, I'm also reminded that I had planned on undervolting my i7 for a while. Another thing to note is that undervolting leads to less damage to the processor over time.
[Atrix 4G Android Development] sambaeallegria:
You were right. No issues with stock voltages.

Now I'm trying with 1.3Ghz version. What method do you suggest to perform downvolting? Now I'm undervolting step by step only low frequencies and then I will try with high frequencies, can it work?
[Atrix 4G Android Development] Twist79:
I use the same UV values in 2.3 and 2.4b as I now tried in 2.4 r2 1.0GHz

I too get random reboots with the new kernel while unlocking with FP reader.

2.3 and 2.4b do not show these problems.

I use the "old" cm7 weekly and not the newest one.

So either this new version needs higher voltage or there is an other problem.
[Atrix 4G Android Development] Mphill46:
Someone pointed something out to me and I want to know if it is true. If your undervolting isn't that kind of defeating the purpose of over clocking? I know what undervolting does, nut how does it effect the performance of the processor unit itself?
[Atrix 4G Android Development] Swiftks:
No, actually its better/cooler. Your overclocking the CPU, while using less power to do it ;)

There seems to be a problem with the newest kernel(0.24r2 1ghz) when playing Words With Friends. Whenever I try to play Words With Friends, it either forcecloses or I have to wait a really long time for it to open. Thanks.
[Atrix 4G Android Development] Swiftks:
You try clearing data for the app, or possibly doing a permissions fix in recovery?

I tried clearing the data for the app and it didn't work. It's still forceclosing or I have to wait a long time for it to open or close it. How do I do the permission fix in recovery ? I use words with friends every day so this is very frustrating for me. Thanks again! :D
[Atrix 4G Android Development] Swiftks:
Don't know if it will make a difference, but try it:

Boot into recovery (preferably Rom Racer's)

Wipe cache partition

wipe dalvik cache (under advanced)

Words seems to be the only app actin this way and for me but it dont do it all the time. Ive tried just about everything! Oh well fauxs kernels are great and id rather have it than not :)
[Atrix 4G Android Development] ricardowec:
Faux

I reported this to you before and will do it again since somehow it repeats in 024 in a lesser degree but it does.

In a real time application such as Power Amp (Double Twist does not use real time processing) after some time of phone usage the sound output starts to get choppy and the way to solve the problem is rebooting the phone.

In 024 the problem appears afetrr two or 3 days without rebooting. In versions previous to 024 (023 down to 020) I had to reboot every morning to clear or "clean" something.

The issue started after 019 I think (after you implemented drastic changes to the kernel anyway) it does not happen with 019 nor with stock kernel. In 023 was so bad that I had to revert to stock. I am running 024 but as i say the problem suddenly appears and solve it by rebooting the phone

Hope you can pinpoint the issue.

I'm using 024 rc2 without any issues so far.

I'm too are not using the last weekly, because with the latest weekly my phone was rebooting the whole time. Freezing during music and so on.

I'm having an issue with 024 r2 (1.00 GHz) where my processor is constantly stuck at the maximum clock speed. This happens regardless of the setcpu profile--so if the profile maxes out at 1000 MHz, the processor is ALWAYS at 1000 MHz. If it's throttled down to 312 MHz, it's ALWAYS at 312. If it's throttled to 608 MHz, it's ALWAYS at 608. Any idea what's wrong?

Yea, I don't think it actually applies the values that you set it. Honestly, all the problems that I have been having lately such as random freezes/reboots were all due to undervolting using setcpu.

Yes, they are not applied. I had it set to 400mV before too but I don't think they were actually applied. Undervolting is pointless because it doesn't make that big of a difference. The only thing it does is freeze/reboot your phone if you have set too low or apps will randomly FC and you won't have a clue what's causing it. At one point I become so obsessed with undervolting that I got my phone stuck in a boot loop twice so I had to flash the rom again. Just delete setcpu and you'll be happy with your phone and you won't have to worry about anything. Just my 2 cents.
