hello everyone...i was searching for an application that disable one of the 4 cores..or 3 of the core..since i use my Beast just for whats app and music..nothing more...my phone is rooted...using omega 10+ stock kernel. ....i feel that stock kernel gives me the best battery life.
Is there a kernel who has the capability to shutdown the cores if the user wish??
There is an application called " Core Disabler (ROOT)" at playstore...but it costs..
and the other core management are just for dual core or dont work.
There is a member here in XDA who is developing a App what i search for. But it keep force closing.
or if i am wrong...please advice me and give me some suggestion.
thx in advance
You can use custom kernel like perseus and under clock and undervolt
scribbled from my note 2 (N7100)
You won't need to take care of shutting down the cores manually. The CPU's logic will take care of that all on its' own. If you want finer control, just use a kernel like RedPill, along with the STweaks app. there is a function called "sched_mc" which influences the way the CPU cores are triggered. Honestly, I couldn't feel much difference, neither performance-wise nor battery-drain wise.
Get a kernel that supports STweak. Open the app and go to the CPU HOT PLUG tab. Scroll down to Maximum CPU Lock and choose maximum number of cores you want to utilize.

Hi all I'm fairly new to these forums, although I have been watching from afar for quite some while now!
I have been trying out custom roms and various kernels and was wondering how do I go about overclocking my device? Only reason I am asking is because I was checking out benckmark results for other devices and noticed some can be particularly high.
Any insight would be most appreciated!
I wouldnt try any overclocking on the HOX because of the heat issues. A more safe and stable way of doing it is changing the govenor of the kernel or forcing cores online. I think you can use core control (in the apps and themes section) to change core behaviour and system tuner to change govenor.

I have now installed core control. Got to admit it is nice having the option to save a bit more power. How much as an estimate do each of cores use anyway just out of interest?

you can download an app called tegrastats to find out more but all you should know is this. once you activate the corecontrol and depending what app you use you should be fine. if i was you i would also use no-frills cpu app. that way you can underclock and would save you more juice

Fantastic! Many thanks for the advice. I have now installed no-frills cpu, and started to tinker around with the settings. Could I ask as I am still fairly new to some of this, when I first went on to the settings both maximum and minimum were set to 1.5 GHz (Not sure if it was just saying this on the app or not or if these are the actual settings) but I would guess this would use a lot more power am I right?

yes you are right. put the min frequency to say 200 or 300 mhz and then press apply on boot and then reboot and you should be fine
so the Galaxy Nexus has a dual core 1.2ghz TI Omap right? thats 2 cores running at 1.2ghz each? or are the clockspeeds split between the cores?
using Kernel Tuner to manage my CPU speed i noticed that when i exit the CPU tab CPU1 goes offline until i hit CPU1 on/off. nice feature to be able to turn it on or off on the fly, but why isnt it on by default?
then after a while, even set to Performance mode and no matter what i set, my clockspeeds drop by half and fluctuate as if i have the governor set to Ondemand and again with only CPU0 activated slowing my phone down immensely!
im currently running Axi0m with Fancy Kernel but have noticed this on the included kernel and in EOS and SlimBean too.
its really annoying to watch Need for Speed Most Wanted fps drop gradually while racing, or even Into The Dead
is this my phone acting up or is this actually a Deep Sleep feature?

Two 1.2ghz cores.

This may be an app compatibility issue. From the market Application officially supports only HTC EVO 3D GSM/CDMA, however it might also work on other devices. Try a different app, Trickster Mod perhaps.

This could be the app too. Performance governor should never fluctuate in speed. It should lock in at the top speed you have set, and never change from there. It could also be that you have something with profiles that changes your speeds/governors when certain requirements are met (under 50% battery underclock and use on demand governor).

There are settings and governors that do disable a core when sleeping, or when not needed in hopes of saving battery. Most don't come with this enabled by default, as there are some folks that run into stability issues with those options.

your right, Kernel Turner is "officially" only supported by HTC EVO 3d. ive used it on a bunch of other phones and never ran into any problems, like my Samsung Intercept and Evo Shift even an Exhibit 4g. will give Trickster Mod a go
by chance do you know if Axi0m rom has only 1 core enabled by default? i had noticed these sames fluctuations in it's built in CPU controller BEFORE i installed Kernel Tuner. actually this was the REASON i installed Kernel Tuner
also i dont have any profiles or apps set up to govern my CPU frequencies. literally have have 4 games, TerrariaHB and Kernel Tuner lol.
ok ive played around with it a little bit and still having the frequencies drop to 537 even with Trickster Mod, both cores are saying offline and i set frequency lock.
i had my phone set to 806mhz Performance, played with it for a few, come back and...well?
here it is AGAIN after just sitting there and clicking apply doesnt change it! i have to change the frequency then click apply and it does, but it only seems to for a few minutes
-_- im an idiot...
"Max Screen Off"
You will press v under status bar for apply with setting otherwise you will never stay at the same set than before
For apply at boot use settings > apply at boot
Don't use performance, it's useless and deprecated, use interactive instead

Hi,
Would anyone be kind enough to list a step-by-step process on how to overclock the Note 8.0 using SetCPU? I'm a new user of this app and I'm afraid I may end up doing some irreparable damage to the device.
I am also just curious to see if I can squeeze some more gaming juice from the Note 8.0.
thanks in advance.

I was going to post a link to a setCPU guide, but its no longer available
Id only push the CPU a little. In order to gain real gaming perfomance increases you need to push the GPU, but in order to do that you will need a kernel that supports it.
I only received my tablet last night and wont be rooting it until the weekend so cant say what settings ill be using yet. my aim is to attempt to overclock slightly and undervolt where I can...
You're not going to break it with SetCPU. If you overclock too much, the system will become unstable, then just back off. Also, the system will shut itself off well before any temperature possible of causing permanent damage was reached.
SetCPU has an option to create a recovery-flashable zip file, which resets the CPU settings to default. I would absolutely take this precaution, as I've had to resort to it on my old HTC Flyer tablet (became unstable, and bootlooped). As long as you select this option, you're pretty safe.
Other than that, just follow the basic rule of overclocking any computer, and push the clock up one or 2 increments at a time, then test for a few hours to see if the tablet is stable under various usage conditions. Repeat until you've either reached a desirable clock speed, or encounter instabilities.
Also, as you may already be aware, higher than "stock" CPU clock steps are normally not available unless you flash a custom kernel.
The trickster app supports GPU overclock on Civato's kernel.
If you're looking to push the GPU that's the way to go.
Thanks for the valuable inputs to all.

Does the Trickster app allow for senario clock settings. Ie. underclock the CPU on screen off or if battery is bellow a certain percentage?
I may have to switch from setCPU to it if it has the same settings and more...
I'm using a wifi 8.4. Is there any way to have only the little cores active for specific apps
Installing a custom kernel could help you control these cores. You could make it where tasks always try to use the least amount of cores and uses the other cores if it cant keep up.
Could I do something with tasker? Maybe a script or something?
I dont know. I use skyhigh kernel and synapse app to control cpu and stuff. It also saves battery.
Yeah, I'm already using Skyhigh. I'll just go and figure something out then
I have been using Yureka for few days and see that cpu cores are always on, irrespective of load. Is anyone working on a kernel which can shutdown 4-6 cores when idle or when screen off? I think this would be great for batter.
Try Cpu Tuner, it has options for profiles and to turn off CPU cores after digging into some settings to enable it as far as i remember.
I am using it. However, the current kernel (as well as Sandy) does not support core shutdown so none of the apps have this option. CPU tuner will scale down frequencies to what i want but all 8 cores are always running.
Like this?
How did you shut down the cores please tell us..

It is achieved with the help of CPU Tuner app. I am using it since I got my Yureka.

Can you share your configuration from CPU Tuner? I can't any option in cpu tuner to shut down cores. Only governors and their affinity settings.

"Simple and Powerful" Config with "Power User" profile.
My CPU tuner was working in non power user mode . Thanks for the info. I can control cpu cores now.
Now only if someone makes a kernel with more governors and automatically shut down cores on low usage . It seem cpu tuner only allows me to set number of cores for a profile.

If I am wrong correct me, if I have understood what you are trying to say, you most probably wish to use the feature where the idle cpu cores are shutdown once the load is not that much.
In my knowledge, that's 'Hotplugging' right ?? coz it more or less does the same function. Try installing some custom kernel that provide you with some really good hotplugging governers. And coz the development for yureka is really in it's full form, there have been few kernels that have been posted in the "Original Android Development" section of our xda forums. Try going through them, you will find what you are looking for !

Yes sir, hotplugging kernel is what i am looking for. Last time i checked, there was just Sandy kernel which did not had this. It seems there are a couple more now . I will give them a shot and update.
