Not really. As faux say not all chips are created equal. I've seen up to an amazing -150 but my phone can only handle -50 stable and -75 sometimes with a reboot or two.

Mine handles -100 just fine, but yeah,others can only go -50. Just use system tuner and hit the -12.5 till your phone freezes, then when it restarts go one less and see if it's stable. That's what I did.

I'd also suggest keeping the Max Clock at a consistent value while you play. E.g. UV -100mV might work well at one Mhz then fail at a higher value.
Mine seemed to work consistently at about -100mV, then again I tend to UC unless I'm running CF-Bench or something
Should I only need to concentrate on the lowest and highest clock speeds it's been set to use? Or will I have to undervolt all other frequencies between the two? Not sure if it increments on usage, or simply toggles between the min and max.
If it does increment, how can I test it's stability on the other frequencies if I can't tell what frequency it was using at the time?
Just tapped the -12.5 button a few times, and it reduced all of the sliders. It's -100 now with no apparent issues as of yet.
May I ask the reason for undervolting?

Mainly to save battery. Altho I have found that it is quite negligible. It may also help with phone heat

I run faux latest version 2.7 beta and I see his scripts to undervolt and the lowest I see it too go is -75 how are you able to go lower to -100.... ???
I think it varies from phone to phone, mine too seems happy enough -100.

If the phone hangs/boots below that level then with the Phone/Kernel/... that's the limit.
I created a GScript script (well a sh script) to U/V after a reboot. I didn't want it to do it automatically as you'd end up in a boot loop. Just hassle to fix. The reason for the GScript was to remove it from the various CPU controllers I'd tried, I ended up just using the CM7 one to control the CPU.
Faux has the command to do it globally (across all frequencies) or individual frequencies. TBH I never bothered with individual ones.
The bottom line is, do what you and your phone are happy with.
EDIT: meant to add you can check the actual value manually. I know the Faux one (same post as the scripts above) but if you are using a different kernel it might be in a different place.
Hello
I am new to this forum and am a long time CM user which I am using on my phone at the moment. However, having discovered the aggressive thermal throttling on this phone (CPU-intensive tasks seem to throttle the max CPU speed down to 1190 MHz very very quickly, before the phone even gets warm), I'm trying to find a custom kernel that will work with CM. I don't care about any fancy features such as S2W or DT2W and if the kernel allows these to be disabled then that would be even better. Basically looking for a reliable, stable kernel that can be configured to be as close to stock as possible, but which would stop the aggressive thermal throttling.
Thanks
Hi, and Welcome!
I'm afraid that your post likely will be considered a "Best ROM or kernel" thread which is not allowed. It's usually suggested that you go over to the development forum and try out kernels for yourself because everybody's needs are different, and so on.

Only Chaos kernel is compatiblewith CM atm afaik because its a CAF based kernel.

I probably will do that, but I thought this might not fall in the realm of "best kernel" because I have listed some specific criteria...

I'll give that a try. From browsing earlier I noticed that n30Hammer and ElementalX have separate links for CM11, I figured they would be compatible.

Hi,
Yes they are compatible too, for ElementalX choose the right version. Both have thermal settings.
There is also: http://forum.xda-developers.com/showthread.php?t=2649458 and http://forum.xda-developers.com/showthread.php?t=2633955 (almost the same kernels apart the Toolchain), compatible with CM/CM based rom with thermal control too.

All you do is make it "best kernel for specific criteria" then. Mods see it all as the same thing.
I'm giving ElementalX a try for now. The mods can feel free to close this thread if they see fit.
Thanks for all the replies.
before this gets locked you need a CAF kernel, Chaos kernel comes to mind, they do nice work. Comes with NXT tweaks which allows you to customize almost everything including temp.
I tried all possible CM11 kernels and Chaos kernel has in my opinion a very nice CPU load management.
Other kernels will stay for several seconds in max frequency after a power demand which result in higher CPU battery drain.
Bricked kernel was also excellent in that field and super responsive but the developer takes a break at the moment so the kernel is not usable for the CAF Version of CM after 25.01.14 without further modding and the AOSP mod for CM CAF is producing some weird behavior on my phone so I go for Chaos and CM at the moment.
I found Elemental would keep upping the minimum CPU to 1267 instead of 300, so at the moment I'm trying out NexXxt as @viking37 linked above, and using Trickster to configure the temps it seems to be working pretty good.

It's normal, it's how Mpdecision from Qualcomm works (for smoothness purpose). Each time you touch the screen the min CPU freq is increased to 1,26 Ghz. In fact the apps reads this at the min CPU freq because you touch the screen to open it. When you stop to touch the screen the min CPU freq will go back to 300 Mhz, the app needs to update the reading of the min CPU freq too but with Trickser Mod it seems it stuck at 1.26 Ghz all the time (for the reading only) but your min CPU freq is 300 Mhz when you don't touch the screen. You will see better this behavior with an app with "live reading CPU freq" like PerfMon or System Monitor.
You can use the "lock frequency" setting in Trickster Mod after set your min CPU freq to 300Mhz, if you want.

Not good option. Only locks core 0. Core 1 still affected.
Only full workaround is delete /system/lib/hw/power.msm8974.so

Hi,
Yep, right

Just thought I'd report back, been using NexXxt with custom thermal config using Trickster, and have had no problems at all, great battery life and no more throttling.

Ah no problem
This is a really strange problem. Over the past few days, my device keeps resetting its maximum CPU speed to 1190Mhz, no matter what app I use to set the max speed; I've tried no-frills, trickstermod, and the built in cm performance settings.
I assumed it was the kernel, but then i switched kernels; i assumed it was the ROM, but then I switched ROMs; I assumed it was an app, but I factory reset and still the same. What else could it be?

i think its normal. you don't have any problems with it right? you can change profiles like 'performance' or 'interactive' if your rom allows you to do this.
think it's probably thermal throttling - use cpy spy, or something that monitors CPU speeds and check

Are checking set on reboot in the overclock menu? You lose your overclock on most roms if this is not checked.

Yeah, I think that's it; I finally got no-frills to force it to stay at 2.4ghz and thermal throttle in logcat was whining about not being able to set the CPU speed.
hello
I have a problem with OC on my nexus 5 d821 32 gb. I have this rom [ROM][N5][UNOFFICIAL] ♦ OptiPurity ♦ Now w/ CM11 Themes [9/20/14] + Uber KERNEL and when trying to raise Voltages about 25 or more on 2576 Mhz I have always restarts in benchmark like antutu. I tried to not give more than 2576 MHz bcs its no sens when its resets. On stock Voltages its this same problem ofc only in benchamrks. Soryy for my English. Its not the best.

when you oc, you dont just raise the cpu speed, but you have to adjust the voltages up or down as well, to get it stable. above 2265mhz, there isnt such a thing as "stock voltage", as stock doesnt oc. you meant the roms/kernels "stock" voltages.

I know about that, so I tried rise voltages +25mv on 2572 Mhz and still get reset in antutu so tried more 50,75 and its this same when I down -25mv phone just freez. Hmm i think its something wrong with phone or im doing some wrong?

25mV is to large of a jump to try. try raising or lowering the voltage 5-10mV at a time, not 25mV.

Bugs:
With hal3 active there will be problems with the camera in third-party applications (the default is off)
The "menu" button is not configurable, is the "menu" always called? QRAttached fileFIX_FRAMEWORK.zip (9.27 MB)
There may be problems with the stock camera (if problems with other cameras do not go away) - QRAttached filemarkw-oss-cam.zip (724.45 KB)
It is possible to "stick" the notification of charging / connecting when disconnecting usb / charging (it is treated by resetting)
Setting it right now, it's surely more updated than Hrafninn's last RR rom, mostly for the new kernel with Wi-Fi updated drivers and hotplug, also with optional lowered Cpu freq at 400MHz. Customizations seems to be almost on par with RR, great!
Let's see with Greenify and some blocked alarms/wakelock, what autonomy can provide :fingers-crossed:

Also it have 2.21GHz max freq. that gives antutu over 65k and geekbench 4.500+. But that 400MHz is unusable. Kernel always switching between 652-2.21 GHz and when i tried to set minimum freq to 400MHz my device freeze and rebooted.

It depends on your specific Cpu and other variables, mine, for now seems to be stable...:fingers-crossed:
Anyway I saw there's a huge NETLINK wakelock denying the deepsleep of my device...Now I've deleted all my alarms and wakelock blocked things and from My Android Tools (maybe I was wrong on something that caused the wakelock) and it's fully charged stopped manually at 99%, let's see what happens. The wifi (maybe a little weaker than Miui) and bluetooth scanning are off. Charging was at high speed with original charger and Aukey "big" cable , Led was switched on immediately, but then I've charged with the device off, to speed up the process, and noticed that there's no percentage, only an empty animated icon. Fingerprint is ok, just few issues when trying to unlock on Nova Launcher's home page! I've found that give root to Nova instead of "administrator's privilege" is resolving this issue (Root is needed to use the "lock now button" with Nova).
I've also set the Low Cpu freq at 400MHz and limited the high at 2GHz instead of modified 2.2GHz. Today I'll test also the "equalizer" system app, that yesterday crashed when I opened up from inside Shuttle music app.
I hope to solve the wakelock problem.

Yes it's safe.It's a small overclock and beside that there are mechanisms like cpu throttling and core offline that prevent overheating.Also the rom is not fast because of that, you can barelly notice any improvement from a 10% speed increase.
What about battery? I'm on ViperOS right now because that Pixel Experience that offer, but I really want to try this one
