Hello there,
I've been flashing kernels since I was in LeeDroid Froyo and got no problems. However since I switched to GB based roms such as RCMix3D and TB Fusion, my phone always freezes when I try setting Kernel-Lee-V3.1.1-2.6.35.13-CALLREC or MDJs v19 to maximum overclock so I have no choice to but to stay on stock kernel. I have no ext3/ext4 partition on my SD card in case you ask.
Current ROM: TB Fusion 1.1.2
Radio: 12.54.60.25U_26.09.04.11_M2
Any idea what should I do to solve this issue?

yes, your handset freezes because the overclock that u do its too high... underclock it at 1200-1400mhz & try...
and configure SET CPU features... like the standby status, etc....but do it with common sense....
think about that DHD proccessor goes by default at 1gz, really when we overclock the processor we are putting in danger the security of our device

Haha! I know that overclocking is quite dangerous. Back on the froyo days, my phone is quite stable around 1.8ghz so I'm just wondering why is this happening (maybe my phone's processor is starting to fry up? ). Is there any effect if I'm using smartass profile on those kernels I've mentioned?

i hope that the processor works or not works (don´t crashes a little bit...)
but the reason of your freezes maybe (almost sure) because froyo & gingerbread don´t works at the same form, and gingerbread need more resources & stability for to work correct... don´t forget that the kernel manages the hardware...
if u force it......... u know what can happen...

it´s possible, take this explanation, read and judge by yourself what´s the better cpu governor...
smartass (Best explanation i've found paraphrases to: based on interactive, but better.)
----
ondemand
Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative
Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance
Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave
Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down

You have mentioned about those "resources", is there any special measure that I need to do or what? I'm using the smartass profile on those kernels but still *sigh*
Anyway, I've observed on your sig that yours is overclocked @ 1.8ghz even though you're running GB, me envy

you only should do a good over/underclock & set the correct cpu governor for your daily use....
well, you know ho is @MDeeJaay? the developer of MDJ kernels and roms...
he explained smartass with this words:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245.

no, no buddy... i only show the max speed nothing more... i set my cpu concretly like this;
CPU GOVERNOR:interactive
MAX SPEED:1113 MHZ
MIN SPEED:245 MHZ
PROFILE: screen off; 245 MHZ max.
245 MHZ min.
in adition i´m going to modify my syg LOL
haha..thanks again. I'm gonna try playing with the frequencies to see which will suit me
i hope someone can make a stable 1.8ghz kernel without the freeze
IT´S POSSIBLE but i don´t want to try it LOL
i love a lot my DHD
Hello, i wanna share my experience undervolting.
For people who dont know what undervolting is, its the power or energy that the battery send to the CPU with determinate clock speed.
For example:
384 Mhz is the lowest frequency of our CPU, it has a 800mv volt in the stock ROM with stock kernel.
So in theory, the battery send 800mv to the CPU when it runs at 384 Mhz.
The effect of undervolt the CPU is bassically get more battery life and at the same time reduce the temperature of the phone.Less energy send less battery used and less hot phone in our hands.
How to Undervolt
Im running Stock ROM with Ruby Kernel stable.
For undervolt you need a kernel that support it, you can do it in all rom if the kernel support that.
If you want to Undervolt, i recommend you to use Trickster MOD.
You can Undervolt maybe -50mv all frequencies and see how it goes. Some people can even in best cases undervolt -200 mv. But you need patience to test slowly.
DONT TICK SET AT BOOT IF NOT TESTED.
That why you cant:
For example if you undervolt -100mv and if not stable, and you have set at boot ticked, it will freeze the screen and after reboot it will happen again.
After you set the mv for undervolt, download from play store CPU stability test and run it.
It will test all CPU frequencies to see if it is stable.
If you dont get any SoD, congratulations its stable.
My undervolt settings are -100 or in some cases -75 mv and very stable. My battery temp is 30 C°.
Thank you very much

What is needed to undervolt?
Thanks for the info. What are your battery stats after undervolting? How does it suffer other operations of our mobile like browsing or gaming etc ?
Sent from my LG-E975 using xda app-developers app
You need to first make a backup, install a custom kernel, install trickster mod, and from there apply what this discussion is talking about. Good luck!

Depends on the kernel. I am using Trickster Mod with Viper ZVC kernel. There are other control apps available -- some of them are kernel-specific, some are more universal (Kernel Tuner, Android Tuner, System Tuner, etc.). Look in your kernel's thread -- the developer usually tells which control app(s) to use with it.

Thank you, I'm using AK kernel with UKM and Synapse app from google playstore. Using E-975 (intl.). Can you suggest if I should change the global setting or the individual settings for frequencies ? I had recently (soft) bricked my phone by running benchmark at ~1900mhz CPU and 487mhz GPU (like a villain, I know. Re-connected battery to save it... phew..). I'm really cautious now and I just want it to be less hot and save some battery, that's all. Any guidance would be really appreciated... thanks

I dont have anymore this phone because some people stole my phone like 1 year ago. Sorry.
Oh okay, sad loss....
Hey guys,
i got a problem adjusting the cpu frequencies on my Galaxy S4 mini GT9195.
For example, i change it to 162mhz minimum and 1026mhz maximum and the smartassV2 govenor. Then that changes ramdomly to some weird frequencies automaticly and out of a sudden. Like 1458mhz minimum and maximum.
I use the cyanogenmod11 M7 rom and the f4ktion 1.5.0 Kernel (the cyanogen kernel does the same btw)
As App for adjusting i use the Kernel Tweaker, but even if i do it in the System settings its doing the same...
I did some undervolting, this stays as i set it.
I hope you guys can help me its annoying to check it every houre and see that it changed again and drains my battery

Devices using a modern qualcomm cpu, relies on two userspace daemons (mpdecision and thermald) to manage frequency and thermal throttling. So mpdecision takes care of the frequencies and cpu hot-plugging (when to engage additional cores or not), and thermald lowers the frequency if the temperature gets too high, in order to protect the cpu from overheating. This is not compatible with the frequency settings in CM or any third party app with similar functionality, as they will always override whatever you set there.

I see.. Thanks for the answer mate, so there's no way to save battery like this? It just seems sometimes that it's stuck at some frequencies...
Well, you could make a custom boot image that disables those daemons, but it could cause more harm than good.

f4ktion kernel 1.5.0 is not designed for M7. For M7 use 1.4.5.
I'm right now with nightly 0703, kernel 1.5.0, mpdecision disable and MSM Hotplug enable (performance control). With this settings that bug disapeared. 162 mhz - 1728 mhz; smartassh3; ROW.
In M7, and 1.4.5 kernel, the only governor that works with 162 mhz and don't change to 1458 mhz is the Ondemand.
Need help or advice , last week i've been using lollipop rom, im not familiar to the new settings and setups on this so i explore and try the kernel settings. I set my kernel setting to maximum, like cpu which is about 1750 mhz all cores and gpu 450 thermal off etc. Because i hve been seen some comment that the lollipop rom reaches to about 27000 k antutu score . i tried it by my settings which is my phone crashed while testing it to about 25% of testing. Now i just go back to sling rom and try again to test with no modification with the kernel or any optimizing the performance and im surprise that it crashed too and tested with putting my phone on the freezer which i guess im having phone temperature problem but it crashed too. Now while charging and testing in the same time it completes the benchmarking of my phone.
I guess my battery is the reason my phone is crashing when on the heavy load of using
Or some hardware issues? Like cpu,gpu ??
Sorryto my bad english and explanation. Thanks

See this thread and check you PVS value of CPU....
http://forum.xda-developers.com/nexus-4/general/poll-cpu-binning-t2052496
If you are getting slower or slow PVS, try to increase the voltage of 1750mhz freq and run the benchmark...
Hope it helps

Thank you . the result of my PVS is 4. I also suspect that i have low voltage to run the processor thats why when im doing benchmark it shutdown even playing COC.
How can i change my voltage and what is the default voltage ? Thank you again.

trickster mod or faux clock app...
i've been using this phone for about 2 years now and recently moved (about a few months ago) to using a custom rom (crdroid 7.1.2). it was running smooth and cool until day the clockspeed decided to lock itself at 2000 MHz (checked using cpu-z). I do not know if this is normal but the phone's temperature goes up to 36C on idle. i thought the problem was with the Lspeed app (+custom kernel) so i uninstalled it but it didn't work. I also factory resetting it, but still not luck. will updating the firmware resolve my issue? if not, what other available solutions are there?

If you are using Fast Charging, that heating is entirely normal (happens to me too)
But heating during idle is not normal. Try changing CPU governor to something else. (like schedutil or powersave)

use Rootify, select the CPU tab located at the top then change it.
The app sometimes gets stuck at Loading screen though.

ok so it does work when i change the cpu govenor, but the only option that actually works is 'powersave' (as well as 'userspace'). all the other ones still sets it to 2GHz. 'userspace' seems to have a somewhat of an improvement but it's only setting everything to a constant value. is there a way have it set to balanced mode?

powersave forces the processor to work in the lowest frequency availible, thus consuming less power.
userspace allows the app to set the CPU frequency whatever it wants. This isn't supposed to be used in Android since changing CPU speed thorough an app is super uncommon.
Others like ondemand normally keep the power low but starts using the higher frequencies if a processor intensive app is launched.
You can learn which governors do what in this post so you can set the most suitable one for you.
