I have a HAVS kernel (Net's 4.2.2 SBC CFS Aggressive HAVS) and as I understand it any sort of CPU Tweaking application will cause conflict and probably a system crash, correct?
Also, can some recommend me any applications that compliment Juice Defender well. I have Juice Plotter already. I am looking for an aggressive auto task killer that's customizable along with any other suggested applications. Thank you!
A system crash is a possibility but they will basically just counteract each other and either make your battery life worse or give a performance hit.
SetCPU helps dynamically underclock/overclock based on certain scenarios. You can set what scenarios you want. Another option is AutoKiller. It isn't Auto Task Killer. Its a different application. Not quite sure how this works but you can research it. However Froyo does a good job managing most applications.
But if you are looking for customization I would go with SetCPU and AutoKiller
Thank's however since I'm running a HAVS kernel I won't use SetCPU. However I will look into Autokiller. Thanks

o.o a ton of people use set cpu with havs... its not setting voltages... its setting the cpu speed...
I just installed setcpu and ran it. My phone crashed about 10 seconds after I allowed root access. Tried twice more with same results.

Its the governors that conflict. Not sure on the exact technical specifics but think of it like OCing a comp.
Some mobos have dynamic OCing. They adjust voltages based on CPU draw. If SetCPU sets CPU speed but HAVS reduces voltage... it would cause a crash. Its always better to have one thing deal with both CPU and voltage.
I'm not a full blown expert with kernels and how they function. All I know is to not mess around with SetCPU + HAVS kernels. It was always unstable or a massive battery drain for me based on my testing.

Setcpu does not do anything that a user with root access and terminal emulator can't. Setcpu does not actively do anything related to cpu speed or voltage in way shape or form. What setcpu does do is set the min and max speed the cpu can scale to and the parameters specific to the governor (up-threshold for one).
The governors also don't conflict with setcpu because setcpu does not do anything that a governor does.
The only things setcpu does is allow you to specify what governors and cpu speeds to use during screen on/off, charging, and battery levels through the use of a gui.
Technically setcpu does not interfere with havs its the settings that cause the issues. Again, what setcpu does any root user with te can do. If you issue the wrong settings in te and your device "crashes" is the user going to blame the settings or te? With the way some people are they would probably claim te interferes with havs instead of realizing that the setting combo they issued is not stable.
Setcpu is a great gui to tweak cpu parameters but don't confuse it with an app that actually controls the dynamic cpu frequency scaling or its voltages.

Ahh there. someone more knowledgable then me explains it perfectly.
I've run set cpu plus haves kernel for the last month... as have almost everyone using savagedzen.. thats what they recommend. If it was causing issues i am sure we would know by now. 100%stable... 0 random reboots! (well... accept for when i didn't follow directions xD)

I believe you and am not discrediting you but how come when I run SetCPU on a kernel with HAVS, it crashes? (Tried 4.3.1 and 4.2.2.) I moved the maximum value from the default 944 by maybe one or 2 notches up and the device freezes and crashes. Maybe Netarchy's kernels aren't compatible with CPU Tweaking programs? Anyone out there running a Netarchy Kernel w/ HAVS + SetCPU successfully?

Again, it is not setcpu it is your settings. You said you moved the slider "one or two notches up" (overclock) from the default 944? The evos default max is 998. Either way, with what you said you are overclocking and your device cannot handle the overclocked speed.
Like I said, you can do the exact same thing that setcpu does through terminal emulator. Instead of blame setcpu you should observe the speed/governor combo you are using.
I can oc my evo to 1.26 on my personal kernel without it rebooting on certain governors but on others it would reboot randomly and I don't set cpu parameters through setcpu, I use te, init scripts, and tasker.

Couldn't have said it better. The common misconception around these parts is that SetCPU has some negative effect on kernels with HAVS and this is just untrue.
Maybe I'm getting some terrible luck. I've always gotten negative results from using both SetCPU and HAVS. Tried different settings and recommended settings from others. As well as trying to tweak it myself. Not working so I just removed it and HAVS worked better on its own.
Sorry for the misinformation.

The common practice with setcpu is to use it to underclock when sleeping. Depending on the governor you use (besides powersave) you are actually causing the cpu to struggle when completing tasks if you limit the max to 245 for example. During sleep if it needs to perform a task and that task would normally complete in 1 second at 998 mhz imagine how much longer it would take if it was capped at 245.
I have had better results not underclocking while sleeping. I would suggest using setcpu to specify to use the conservative governor when sleeping, ondemand/interactive/smartass when screen on (depending on which one you want), and interactive/ondemand while charging without under/overclocking at all and using the default freqs (245 - 998). I'm certain you would be surprised at how your evo behaves after that.
I don't know though... if race to idle applied here why would phone manufacturers ever under clock their phone? It kind of confuses me. Rti applies to computers but not phones? doesn't make sense.

My last post may have been a bit confusing so I will clarify. When I said underclock I was referring to the practice of capping the max freq to 245 which is what most people do. If you cap the freq at 245 you are essentially underclocked all the time and would cause your cpu to work harder.
The evo underclocks automatically when the cpu load is low enough (idle for example) to save on power, reduce temps, and to basically keep the system running. But I would assume that most of us who have used setcpu have seen how lousy the evo runs when it can't scale up (locked at 245) when using the evo. The governors will underclock the cpu on their own if the device reports it does not need the higher freqs and this occurs during sleep/screen off as well.
Ugh this is quite frustrating. Perhaps it's the current kernel I'm using that's the problem?

Have you done testing to make sure your phone plays well with the more aggressive kernel? If using SetCPU is causing your phone to reboot then you may want to adjust your overclock, switch to the less aggressive kernel, or update to the newest netarchy SBC powered kernel; 4.3.2.

I'm not sure how I would go testing my kernel? I mean I've been using it since yesterday morning and there haven't been any FC's/phone crashes or anything strange so I guess the aggressive HAVS works well with my phone. I'll try upgrading to 4.3.2. I'm assuming it works fine for you?

This.
Very sound advice and yes some evos can't undervolt as well as others. Always remember too that the stock kernel for the evos use CFS. If you are using a bfs kernel that could also cause issues. Some evos run better with bfs versus cfs but it's really going to come down to the amount of time you want to put into testing and confirming what your evo likes.

Yeah, it does. How far are you trying to overclock before your phone freezes/reboots?
Does anyone have any recommended kernel settings they'd like to share? I've been changing things around a little but I'm too afraid to make any big differences as I don't want to ruin anything. Any recommended GPU clock settings would also be appreciated!
Also, I see people mentioning they're overclocking their phone a lot. Does overclocking on this phone mean it constantly stays overclocked until you change the settings back or does it change frequencies as needed to a maximum frequency that you set?

Hey When you OC lets say to 1800mhz . That means your proccesor can Amp up to 1800 mhz if needed. Your phone will always idle when its a sleep. My setting are 100mhz UC and 1800mhz OC. Gpu is also Oc to 640mhz. I use pegasusq for governor and cfq or zen for scheduler. I also use eco mode . I get very good battery life and performance.
Also...what apps are you guy using for this? Seems most use trickster... Wondering if anyone has experience with others.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 4
I would use whatever the developer of your rom/kernel recommends (which is Trickster most of the time)
Anyone know what eco mode does? I've been looking it up but all I've been getting is this guy's kernel that he named 'eco'
Also, for anyone reading this thread with a similar question to mine I'd heavily recommend using Zen over CFQ as a scheduler because it's much smoother and no jitters/stutters (at least in my experience)
Sent from my SGH-I317
I'm curious what Eco does as well. Tried looking it up, but didn't find anything useful.
Trying out Zen...been getting some annoying hangups and jitters with this kernal. UC 100 OC 1704. And FYI...I've used the stock clocks and still got the same lag and lockups and screen freezes. Also tried on demand gov.
Could it be that ZRAM is enabled? Not quite sure the benefits of it.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 4
Do you have eco mode enabled? Also, maybe you should look into Seeder. It sounds like it's perfect for the kind of problems you're having. Or you could change your minimum voltage from 100 to 200, I heard 100 can be kind of buggy sometimes

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.
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.

Thanks for the help!
This is my first post on XDA. Recently, I got a POCO F3. Today, I tried various combinations of mods and custom firmwares and when I check in Franco Kernel Manager, my CPU min and max frequencies are chaging bby themselves. This is just with root and custom recovery installed. I thought a custom kernel may fix this, but it didn't (I tried Immensity-X, WildAngel Performance and NoGravity). As well as that, I'm finding that the GPU cannot handle an overclock or else the min and max frequencies will also fluctuate by themselves. The overclock I tried was to 682 MHz (my F3 isn't a silicon lottery winner). Does anyone have any idea as to what the issue might be?
you try flash last build NoGravity Kernel v1.0.1 + NGK App 6.1.1 (Hotfix) ?

Xiaomi does some crazy ass throttlings that limits cpu freq to 2.7k default and keeps changing with temperature 37*c, 39*c, 41*c and so on
same with gpu, gpu is not limited but it starts throttling at higher temperatures too but the problem with gpu throttling is that it doesnt revert back to highest when the temperature cools down, you'll have to revert it manually.
only way to fix this is if you edit the thermals yourself or use dynamic profile or flash thermal no junk

You can fix the freq. of both CPU and GPU to be max, and disable the mi_thermald. Try "extras/jitter-reducer.sh" in USB_SampleRate_Changer which has been developed for hi-fi audio use. But this can disable almost possible battery saving features, e.g., GPU power level, thermal throttling, doze, wireless connectivity optimization, etc., to avoid jitter distortion on all digital audio outputs.
Note: this is tested only on the STOCK kernel.
