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.
Hi im thinking of doing a overclock to 1.5 ghz is it safe for the processor and the battery life witch already sucks. has anyone on here whos done it using setcpu and the rom had any problems after doing so ? and how much faster is 1.5 ghz compared to 1.2 ghz on the galaxy s2 ? and is it safe in general for the hardware of the phone will the phone get hotter or have over heating problems ? also what should my settings be for minimum maximum and the voltages ?
Of course oc is going to make ur battery life a lot worse.

I haven' used Setcpu in a while but I believe it's got a feature to stress test the settings to see if it can handle it. Generally the worst that happens is it'll crash. So long as it doesn't get hot. Heat=death for electronics :')
I'm using tegrak (from market) to overclock to 1.4. I found 1.5 was too unstable. Noticeable difference between 1.2 & 1.4 is almost none. Also voltage increase of 50mv was needed to gain stability. There is not much point of overclocking the device IMO unless like me u just get some satisfaction out of knowing its running faster!

This is true. I see no difference between 1.2 & 1.5ghz. But that doesn't keep me from running it at 1.5 when I'm playing a game anyway :'D

Well it's not safe, that I can say. Nothing is safe when you don't know what other things are changing with the clock rate. But still you could do that. You just have to make sure that the temperature is within limit, it will be definitely high, but make sure it's not that high.
And upping the clock rate to 1.5 GHz won't drain any extra battery than 1.2 GHz.
Regards.

I tried the overclocking and each phone is different, increase then test, there are many benchmarking apps out there, I was stable at 1.4, my kernel does not include 1.5 GHz, and irregardless of what people may say, running the phone at higher clock speeds consistently DOES drain the battery more than 1.2GHz, unless you have found a way to manipulate the laws of physics. I don't see how one can fathom the thought that you can get a faster CPU at absolutely no cost.
Many people think when the CPU running faster means you complete tasks faster, hence 1.5 would complete a task faster than 1.2 and hence save battery, but I believe we use this phone as more than a calculator, so when you are performing a task that causes the CPU to run at 1.5 for a period of time e.g playing a game, browsing or whatever you do with your phone, then the CPU has to draw more power to keep the frequency at 1.5 as compared to the CPU running at 1.2
All in all, I dialed back because I was doing fine without it and I did not need it, other people may need it, and I wasn't gaining anything. to answer your question directly, it all depends on what you do with your phone, I'm not a huge gamer or anything and the 1.2GHz has proven to be more than enough for me to have a very pleasant experience using this device
Using it occasionally is safe, unless you stress your mobile at 1.5+ ghz for more than an hour or so.
The cpu governor will only make use of higher frequencies when there is a need, so mostly you will see your mobile idling at 200 mhz.

Not necessarily a lot worse. It depends on how you are using your phone, and what is causing it to run fast. If overclocking allows the phone to spend longer in deep sleep state, your battery will win. If its games, and by OC you achieve a higher frame rate, then the phone is doing more work, and this will be reflected in the battery life going down.
Most of the time, screen on is going to dominate. If you are a low screen-on user, I guess there is more chance for a higher max_cpu to be beneficial (it won't be used unless there is a task that requires it). More accurately, it helps some of the time, so the net result is not always obvious to predict.
How about undervolting?
Any danger in doing so- other than crashing when voltage is too low?
Before over clocking it might be worth downloading cpuspy from the market and seeing what time you spend in each speed.
Chances are most of the time you won't even hit 1.2 so might not have anything to gain by over clocking.
Then again I dont know how you use your device but I do know I was surprised when I found out.

I've played with the SuperSonic version of this phone (which has a 1.5Ghz core) and the results from photos/video are much better, I'm pretty sure the cameras are exactly the same but the SuperSonic benefits from the higher CPU.
I think it would be cool if somebody could write an app that states
IF user opens Camera application voltage + clock speed is increased to allow stable 1.5GHz speed
WHEN user closes camera application overclock turns off.
Thoughts?
You have a smartphone! Not a pc!
I didnt see any advantage if you oc to 1.5
Btw In normal use your phone keep in 200mhz not 1.2.
I think i only hit 1.2 two or 3 times for 3 seconds in a full battery cycle.
Sent from my GT-I9100 using xda premium
oc dosnt make sense ,there no noticeable diff,an yes very few times i hit 1.2 mostly its on 800 or few times on 1000....using a device with 1.5ghz proccesor an oc a device to 1.5 ghz which has 1ghz processor is very diff in nature....
Fair enough.
Well I wouldn't mind an app that mazes out at 1.2GHz with camera app open, as it can lag when shooting HD.
oc upto 1.4 ghz is fair enough, anything more than that is a waste. though you cant find any visible difference between 1,1.2 and 1.4 it does helps in maintaining smoothness on some situations.
yes very true i had oc my sgs1 at 1.2ghz and sgs2 at 1.4ghz but frankly i dint see the diff so after few days use i turnd to orignal settings....but many use oc an phone works fine,but depends on personel use......an yes as bala_gammer says its fine on 1.4ghz......cheeeerz
is overclocking galaxy s2 to 1.3gh safe

hey mate
u really think 100mhz would make that much change? its safe btw... seen people running s2 at clock speed higher than 1.3ghz
Plz help @..Longtime hd gaming(gta sa,nfs mw , asphalt,modern combat...) using 1.4 ghz is safe?
I also noted that gameloft games are makes more over heat for phone..
Which is the best and safe voltage level for 1.4 ghz 1250mv or 1275mv or 1300mv
Iam using siyah v6.0b5 kernel with wizzedkat 3.1..

after root... i have installed SetCpu, i have overclock my processor to 1.6ghz.. the question is, can i use this setting for daily use? is it will cause my processor hot or damage??
Depends on the phone. Mine can't run above 1.4ghz stable (but my GPU can overclock easily).
^What he said. Try it for a while, but if you get reboots or freezes, pull it back to 1.4 or 1.2.
if it runs stable then you can no problem
Watch your temp. Might be a phone but it's the same as a computer. That reno gets to high, and you're looking at overheating and possibly causing corrupted files from shut downs or worse, hardware damage.
Correct me of I'm wrong.

Just make sure you don't check "Set at boot" until you're sure you can set it at 1.6 with out reboots and crashes...... GL
Why 1.6ghz all the time? 1.4ghz uses MUCH less power (meaning less heat as well) and is 99% as smooth.

Very good point....
I underclock to 800 . And phone is just as snappy. Why would ya wanna use 1.6 out of curiosity ?
Sent from my SGH-I777 using Tapatalk 2
Honestly the only reason someone would overclock to 1.6 GHz would be for bench marking, which i find useless. My processor is usually clocked to 800 MHz and i can play games like N.O.V.A. 3 with only slight lags here and there.
I do something similar to a few people here. I keep it at 800 most of the time and bump it up to 1000 when I'm playing certain games. Then back to 800 when I'm done. Responsive enough for whatever I have to do and doesn't overheat.
Wow OP
What a question OP.
I can't believe no one called you out yet.. I will be the first
If you want to kill your phone hardware then keep it at 1600! (which is overclocked too you dummie)
USE SetCPU so that your phone can
1. remain cool when high CPU cycles are needed
2. save battery by making profiles especially for when your phone screen is off

ok theres good guides out there. just google it
Happy new year everyone!
So i am using drastic ds emulator in my rooted galaxy s2 I9100 and it keeps heating up in most 1 hour...
I have downloaded trickster mod to change max and min frequency of processor,but i can
only access not too many frequencies:
min=200Khz,
500Khz,
800Khz,
1Mhz,
max=1.2Mhz
I also downloaded the donation key,and there is no change...
I just want to stop my device from heating up when i play drastic,can anyone make any suggestions??
hmmm simple advice dont play the game
coz you think that reducing the processor frequency would help actually making it worse
coz when you reduce it the device needs more power to run the game so puts the device under pressure causing heating
next time try to put it on maximum frequency but im pretty sure even by then you'll experience heating
(s2 basically has heating issues)

thank you for your advice... Its pretty cool to have ds for your phone and play anything you want whenever you want.
So in fact the only solution would be to afford another phone?? ...
So in what terms does a nexus 4 has more capabilities for emulators than a galaxy s2?
Is it because of its processor,the frequencies or what??
Well its like you know for eh if a game need a heavy load of memory and a huge amount of processor speed.. Let's take a simulator need around 500mb or memory and 1gz to run smooth
In s2 it's hard since we have only 800mb and 1.2gz dual core even though the processor supports the memory matters a lot
Where in the case of nexus 4 we have ample amount of memory 2gb and as well a quad core processor which is by default can handle and game easily

Keep in mind that english is not my first language, and I'm posting here because of the visibility and because my device hasn't got a section.
I own a galaxy ace 3 LTE, Qualcomm MSM8930 Snapdragon 400, dual core 1.2 ghz with adreno 305 and 1GB ram, android 4.2.2. Sounds quite good, but something really bothers me... The stutters.
This phone stutters noticeably when scrolling (anywhere: stock browser, third-party browsers, on sms list...) and in VERY BASIC 2D GAMES, like Line Runner, Doodle Jump, Impossible Game. On this game, I found that it stutters a lot more right after I touch the screen to jump.
My previous device was an LG L7 II, with 768MB of ram, a dual core cortex a5 1 ghz processor and an adreno 203, and it was WAY better in this regard. Those 2d games worked like a charm on my LG phone.
Other than that, the phone is fast and can run even heavy 3d games with little to no problems. And I only have some basic background processes running, such as phone processes or gcm service.
Already tried developer options (all of them), different governors, I/O schedulers, greenify, frozing samsung junk, seeder, factory reset, flashing the whole firmware again... Nothing worked.
Samsung pulled out some updates for this phone, but the problem is still here. Please, tell me if there's something else I can try, or at least if this is a problem that Samsung can fix with an update or is an hardware fault.The phone is perfectly usable but this is REALLY annoying.
I forgot to add a thing: depending on the app, stuttering while scrolling occurs more or less frequently. But it's always there.
Stuttering in 2d games makes them more difficult and look like sh...
