I learned in an earlier thread (here) that the Zenwatch 2 is throttled down to only 1 core running at 800Mhz. My Zenwatch, while not totally unusable, does seem to be sluggish at times, and I would love to unlocked those cores to see that sluggishness disappear. As the title says, is it possible to unlock the 3 unused CPU cores on the watch? Maybe even get them running at a default clock set by the processor? I'd be willing to sacrifice battery.
Can anyone answer this question? I´d like to know as well...
Maybe Asus will reactivate them in a future update?
Would it somehow be possible to use a root app such as perhaps kernel audior to force the other cores to work?

Just as the question states. I know the second core will sleep when not needed but say you launch an app, does the second core help load the app? The reason I ask is because I'm curious about the raw speed difference between the atrix and inspire. Now compairing the inspire running at 1.8 and the atrix seemingly stuck at 1 per core (I'm not saying the atrix wont ever be OCed but I'm just talking about what's currently available). I'm just curious if the second core will help the first with tasks. If it doesn't would that make the inspire technically way faster (obviously battery life may be an issue but this isn't a battery compairo)?
Thanks for any insight
I think you should start by knowing that overclocking ARM prroccessors gives little yield.
XOOM at 1.5 ghz scores only 500 better than a non-overclocked xoom on quadrant.
I'm going to try and simplify the answer for you.
Will BOTH cores be used? Maybe. First off, is the app itself optimized for dual core, or does it even need dual core / multithreaded capability.
Secondly, and I think more importantly, what is the rest of the phone doing. So, let's say you fire up your favorite app, the phone is still doing stuff in the background. Maybe it's checking email. Maybe Google Latitude is checking your location and updating. The point is - the other core will still be around to offload this work.
Now, WILL it go to the other core. Maybe. Maybe not. I do work on some big Sun machines, and have seen them use one or two out of 64 cores, even with massive loads and each core being used 100%, it refused to balance the load amongst CPU's.
Hope this helps.

Yea that's exactly like I figured, I was kinda going off Windows/Intel multi core setup. Even after dual+cores have been out for quite some time 95% of programs made still don't use more than one core (Most of those remaining 5% being very CPU intense programs PS, Autocad ect.). But I get what you mean, the one core will be dedicated to what your doing and not sharing cycles with anything else because core 2 is working on whatever pops up. So basically the Atrix might be a little slower at doing things BUT it will always stay the same speed with less/no bog.

So you're saying Quadrant suck as it does with most phones or OCing the Xoom (and Atrix) wont really do much?
I already built an apk for testing CPU usage on both processors... When I get some free time, I'm going to turn it into a widget... Here's what I noticed:
Because of the current OS and less dual core support for apps, the phone kind of kicks certain tasks into using the 2nd processor. The APK i built reads the '/proc/stat' file and i've noticed that when the 2nd processor is being used it actually shows up in the file as 'cpu1'. However, when it's not being used the 'cpu1' line does not exist and you can default the 2nd processor usage to 0%. It seems like performing core OS tasks (like installing apps) kick the 2nd processor into use, which is what you can expect since froyo supports dual cores.
Like everyone says, I'd expect to see more dual core usage on 2.3/2.4 (whichever motorola gives) and when more apps are designed to kick certain threads onto the 2nd processor.
I just bought a Craig cmp741e Android tablet. On the box, it says it has 1.3Ghz cpu. I rooted it. I installed System Info app, it shows my cpu can reach up to 1.3Ghz. I installed multiple overclock app, like cpu tuner, system tuner pro, etc. They all said that my cpu was set at 1Ghz originally. When I try to "overclock" even above 1.2Ghz, os crashes. How come a 1.3Ghz cpu crashes at 1.2Ghz? And how did the manufacturer rom lock a cpu at 1.0ghz? Any way to fix it?
Thanks.
just sell it and buy a new one...
Only way to "fix" it would be to install a custom kernel that has those frequencies. Off brand companies like that aren't really regulated that much. They can make pretty much any claim they want. Most people buying these things have no idea to even look for something like that or care to. The manufacturer will just chalk it up as trying to get better battery life. As far as it crashing, it might not actually be able to run at 1200. There's always certain "steps" or frequencies devices work with and setting random ones might interfere with some other processes. They also might have another script/app/process that regulates it and doesn't allow you to mod it.
My main question is ,why the android devices are not being sold rooted already?
why are they unrooted?
will a rooted device with 4 or 6 cores,running a PERFORMANCE governor,run faster than a iphone's dualcore A7 or A8 ?

android phones and Iphones are not usually sold rooted or jailbroken, because you have full access to the system and can brick your phone in 2 seconds if you don't know what you are doing(this is 2/3 of consumers) I phones are junk IMHO bc they restrict what you can do. also, It is not solely the cores you have, it is also the frequency that they run at that determines how fast the cpu is.
Buy a Zopo, the last Models (KitKat) come with root.
The governor only "say" in witch way the CPUs will clock fast er and slower. The max Performance is given by kind oft CPU (Tegra, Snapdragon, MTK) and the frequency.
And don't forget that this bitten Apples send all processes in background when a finger is touching on the display and the UI will get all CPU.
yea.keep going...
just tell me ,why should i buy an android if i wanna just to make my work with my mobile?
i just want to make calls,use facebook,use viber (all together ) and not lagging'
if i make all cores work together at android,will i achive a better performance than iphones?
(i dont care how apples works.they are just fast)

Running all cores at full blast will kill your battery and cause overheating and shutdowns. With your Android, all cores do work together, when needed. And when not needed, some cores will be at idle and active cores won't be running at full speed.

my question is still the same.
if i enable ALL the cores running together,not necesserally at full speed,will i be faster than an iphone?
would you buy a car that has been modified by others? so as the phone

My answer is the same. DON'T DO THIS.
Because root is useful only for users who know how to do with it?
Well, i want to know what it says on the title. Is it possible to make al core at the same frequency? I have a Xiaomi Mi4(Snapdragon 801), and i noticed that on some new devices(Moto G4 and Moto G5) there is no mpdecision, but the cores scale at the same frequency, and AFAIK that is more efficient that only 2 cores scaling at the same frequency and leaving 2 cores off.
So, thats what i want to know, how or if its possible to make the 4 cores scale at the same frequency so it doesnt need to get at the max frequency most of time(like usually does because it uses 2 cores most of time), or it is related to kernel or if i need something to do this.
Thanks in advance!
I'm no expert but probably not. It's most likely the way the CPU is designed that decide these things.
Well, the thing is that the cpu it's kind of retard, or that's what I think, because most of times it prefers to make lags before turning on another core and that's the problem, that's why I want to know if it's possible to change that or it's hardware related
I have a Samsung s20+ SM-G985F model with an exynos 990 cpu, and cpu socks so fckn bad that I had to root my phone and close and limit cores down. It solves the problem, and I like how Fraco Kernel manager has profile per app.
But I was wondering is there a way to create a profile to close all cores except one when the screen is off? I Don't know how to do that in franco kernel, is there a different apk that can do this?
thank you for future answers
Don't think it makes sense to programmatically disable cores on a Quad-core CPU, because most times only 1 core is in use.
