[Q] All apps reporting 1 cpu core! - Galaxy S II Q&A, Help & Troubleshooting

Hello,
im a new Galaxy S2 (international version) owner.
I remember quadrant reporting 1 cpu on the stock os (2.3.4) aswell, but didnt try other apps.
Rooted, then updated my device to Android 4.0.3 (ICS ressurection remix v9.6) using the safest methods avalible today (runme.bat + flash cwm via odin + flash rom via cwm)
The ROM includes this kernel: i9100XXLPH
The following applications are now reporting 1 cpu core:
Quadrant
CpuSpy
Elixir 2
Linpack
native "top" utilily, via a terminal emulator
native /proc/cpuinfo
Linpack scores 70+ MFLOPS at 1.2Ghz (multi-thread)
I can hit 4000k points on Quadrant Standard Edition aswell
Is this normal? Im confused. It's the dualcore exynos, but everything reports 1 core.

Anyone? Great forums. Cant post to real threads and here this thread just dies?

Your life must be so awesome when the biggest problem is that your benchmark programs are reporting one core.
Mine correctly reports two, when it's using enough CPU to turn it on.
Not that I ever noticed a performance difference even on GB if I forced one core offline.

Please don't make the exact same thread in two sections of the board. That won't endear you to anyone on here.

The 2nd core pops online when needed, so won't show all the time, that's normal.

Miss reporting cpu speed.

Hello everyone I recently purchased the Samsung Galaxy SII about 12 days ago and so far I like this phone very much. Last night I downloaded Quadrant standard I was looking at the system info and noticed that the current cpu speed is running at 1000mhz and max speed is 1200mhz and core is 1. Is it the program miss reporting the hardware or do I have a problem. I goggled this issue came back with nothing related to my phone. Sorry can't upload screen capture I haven't posted enough.

The SGS2 changes its frequency between 200mhz to 1200mhz.
Also the 2nd core is hotplugged when needed to save power.
Thank you for the quick response very happy it's software and not my hardware.

[Q] Is Overclocking Galaxy s2 to 1.5 ghz Safe ?

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

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

CPU dual core Question

Hi;
My question's is when I check "system info" on Quandrand Benchmark, sometime it shows 2 cord, but most of the time it show 1 cord; does anybody know why; if there's a reason, is there anyway I could set the CPU running 2 cord all the time.
I noticed this the only reason i could grasp was maybe the phone wasnt doing enough work for it to see both cores functioning at the same time when i tried antutu i think thats what its called it showed me 2 cores if i had music running in the back ground if that makes any sense, i presumed it would just show both cores like yourself
Quadrant is NOT optimized for Dual core devices. So whatever it shows doesn't matter.
You've to do nothing to run the device on two cores, it will automatically run when it needs to.

Just to be sure, disable power saving mode before running a benchmark.
This will adapt CPU frequency and number of activated cores to the system need.

You have to flash a compatible kernel to enable this feature.
Lulz Kernel or Siyah Kernel.
http://forum.xda-developers.com/showthread.php?t=1263838
Then use Tegrak's 2nd Core application from market.
https://market.android.com/details?id=com.tegrak.secondcore
With this app, you can have the cpu run in
1) Dynamic Hotplug Mode, which is the stock behavior where in second core is active only when the load is high.
2) Single core mode, where only one core is active even if load is high.
3) Dual core mode where in the two cores are always active, even at low loads.
Option 2 will give you more battery at the cost of performance.
Option 3 will give you more performance and higher benchmark scores at the cost of battery.
I downloaded 2nd core from market; however non of those option can be highlighted, I am using [email protected] #23 as my kernel.

Second core

Can anybody enlighten me or point me to a thread as to why the second core only works when I have setcpu installed on my resound?

Second core only comes on when it's needed, and Gingerbread really wasn't designed with more than 1 core in mind. http://forum.xda-developers.com/showthread.php?t=1461875 Search is your best friend.
Be happy it does, I spent 3 days trying to figure out why my 2nd core wasnt coming online. I finally found a post about it on xda.

Even then, when it's needed, and using ICS it doesn't turn on unless you're using SetCPU.
If you want to enable it manually do this from either "adb shell" or from the console on your phone:
Here's the full command string:
su
echo 1 > /sys/devices/system/cpu/cpu1/online
I know benchmarks don't really mean that much but with my second core enabled and both OC'd to 1.7 GHz while on Newt's Senseless ICS, my scores destroy the GNex and anything I was getting before!
Antutu: 6,929
Quadrant: 3,594

How is the battery life after 2nd core is activated ?
Thanks
I dont see a difference, as each core shares responsibility. So instead of one core being at 1.7ghz each core an be at 850mhz. Although sometimes the one core will max out without intiating the 2nd core.

Pretty crappy, but then again I have it at 75% brightness and the performance gov set to 1.7 GHz and 192 MHz with the screen off. My phone was fully charged at 1 PM, and it's currently at 45% using the standard battery. I only ran a few benchmarks with antutu and quadrant and a few other less intensive things. Looking at the battery info 78% of my battery usage is from the screen.
Try the AnthraX kernal in the development section. I believe its clocked at 1.51 to force the second core to turn on.

I have it up and running, so far so good.
I just tried it and it will boot up for me but the touchscreen won't work. I'm using Newt's Senseless.
System Tuner Pro will allow you to force both cores online. Also it overclocks and undervolts aswell.

It currently only works with GB roms. Ignore me if Newt's Senseless is one, I thought it was ICS.
It is an ICS ROM I saw some people had it working with ineffibilis so I decided to give it a shot for the hell of it to see if it would work.
You dont need to force the 2nd core on, it will kick on. If you arent using setcpu that could be an issue. Antutu doesnt work. Also use cpu usage monitor and you can see both cores work.
Sent from my ADR6425LVW
Just a note i read on one of the kernels they stopped forcing the second core on because it caused issues. In the end i truly believe it would be unwise to do so. Let the cpu do its thing. Im on bamf 1.02 and my second core kicks on when it needs to.

so it's wise to use setcpu over antutu? I'll have to try again since I usually get freezing using setcpu with all kernels. no oc nor uv. might just be a bad combo between undeclock and current governor
I just tried enabling both cores with system tuner pro and it worked but evening started going a little jerky. I disabled it again and everything was fine again.

Yeah forcing 2nd core online is a bad idea. Using setcpu, oc max 1.7 min 192. No profiles no uv. Using cpu usage monitor to view cpu usage.

About cores,tests...

Hello everybody,
My friend and me(we have s-on and ics stock last version) when we tried quandrant we usually get 2700 scores.But he told me yesterday he tried different way that he added one line in "buid.prop" and he got 3600 marks quandrant scores
When he opened quandtrant benchmark system information he saw just 1 core is writing.He thought we should see 2 cores because we have 2 cores and ics (even leak)version.
So he wants to added in build.prop ''persist.sys.ui.hw=1'' and he wiped dalvic cache and cache and fix permission then restart system.He checked quandtrant standarts and he saw that 2 cores were writing there and immediately he got run full benchmark and got 3600-3500 marks.So we think that the reason of 2 cores.
But when he checked after 20 min later it was writing again 1 core in quantrand system information.It s chancing by itself.we can get more performans? is it possible to keep it?
I remember some guys talking about cores and they told just check antutu you gonna see 2 cores.Second core works when need it.But my friend added ''persist.sys.ui.hw=1" this line in build.prop and maybe he made 2 cores active So what do you think about it?Maybe somebody try this way and share results with us?

The first few pages of this threadhttp://forum.xda-developers.com/showthread.php?t=1616669 talked extensively about dual-core and quadrant scores, and I would say by page 10 it was agreed upon that quadrant really just sucks. Go check it out, maybe that will shine some light for you..
I remember reading about how ICS improved dual core support, and I could have sworn it was on developer.android.com but I can't find the article that explains it now(and too many results to sift thru) - but basically the tweak "persist.sys.ui.hw=1" would have been found in gingerbread roms, because it DID increase performance, however with the way ICS handles the threading of dual-core+ processors that shouldn't do anything.
And before someone comes in here and says this in a not-as-nice way, be careful using quadrant benchmark as a tool- if ONE little detail is different, you will get TOTALLY different results! A different launcher, a different setting, or even having different background processes or having recently run a different app will change the score TOTALLY. Run it 10 times, chances are it will put out wildly different numbers - now go run 10 apps, then go back into quadrant and run it 10 more time - again, wildly different numbers, no consistency.
Besides, all that REALLY matters is your experience - if your score goes up a thousand(consistently somehow) but it doesn't work noticeably smoother, faster, or better- then what does your score matter? You could add 2 more cores, another gig of ram, better gpu - but if you can't NOTICE a difference then what would the point be?
It is easy to find why people added 'persist.sys.ui.hw=1' to gingerbread, but I can't find ANY documentation/posts that give a real reason to add it in an ICS build.. hope this answers your question.
And if anyone can find the link to googles explanation on how ice cream sandwich handles multi-core cpus compared to gingerbread can you PM it to me?
Thanks my friend your answer.Just ı got that if use quandrant benchmark test when ı check system information if ı see 2 core ı get 3500 marks but if ı see just 1 core system informatin ı can get 2700 marks.
So it depents on cores ı see.Its fault of benchmark app or our phone works one core just when need it use second core?
