Ok so im rooted and overclocked and was using setcpu then decided i wanna try something different so i tried system tuner! When i checked the cpu it said that one of the processors are off line! Then i pressed the info button and sure enough it says only reading one! So i went through the settings and found force both cores online!
Since then i have no lag and virtually no checkerboarding on the web! Anyway i was just wondering if im the only one who noticed this and maybe it could help those who say that they are still getting lag on they're roms using dag's kernel!
Also i hope devs will notice this thread since i can't post there yet and take advantage of this how ever they can!
Now don't quote me on this but most likely the second core only turns on for processor intensive activities such as high graphics games or multiple programs running at once. I do find it hard to believe that it would be totally disabled. Most likely this is done to conserve battery.

Nope i checked that i had 10 apps open two were games (dead space and gta III) One cpu online even on performance! I see 50 views i hope others chime in and let us know what you are thinking
Btw they Did this i heard to the galaxy nexus with the tiomap 1.2 so we'll see what others find

Okay if this really is the case I could also see at&t disabling the second core totally to save battery because of lte but i guess it will take a dev that has more experience with how qualcomm's multicore cpus work in android. report back with differences in battery life like how much faster does it drain now that both cores are forced on.
if you want both cores on click on boot settings and enable force all cpus online. that heats up your phone and eats more battery though+I do not see any benefits doing that.

I've had it like this for 4 days on average i will take of the charger at 8am now is 8:30pm and i have 27% but i use my navigation for my Job! By 10:30 or so ill have 15% and recharge!
Settings

Both cores pushing
Screen off

Tomorrow ill post some pics of battery life usage!
And my phone doesn't get any hotter than normal not even while using my navi! Mostly it just gives no lag and better rendering in the browser/maps/etc!!
I was under the impression that Gingerbread didn't fully utilize multiple cores. Need HC or ICS...

Same, but having a better processor helps. Like exynos. I bet once we update to ics if it ever happens, the differences will be only minor between processors, as it runs so nice.
Got system tuner pro, and it shows speed bars on both cpus running? I didn't change a thing?

Really? I switched Roms twice today and had to reset that each time! Cpu.0 online Cpu.1 offline! Like i said am i the only one? Lets hear from more people and let us know of any lag or rendering changes after turning on both cpu's! Battery too, i'll post mine tomorrow.
I thought I'd play and I have CPU0 running and CPU1 running.

Not entirely true.. the Galaxy Nexus has a kernel governor that turns one core off when the SCREEN IS OFF, but not when the phone is being used. Multiple kernel creators have since implemented this into their kernels. It is called "hot plugging" and it just turns CPU 1 offline when the screen is off and turns it back on when the screen is on

Just checked mine, rooted and OC with DaG's 0.1 version (first version). When I looked, it said the second CPU was offline. Changed it to online, we'll see how that impacts battery life.
How much of an advantage is smartassv2 anyway?
I just tried this with system tuner and both cpus were working but wone was of and on and zero was always on.
I am running stock rooted. If you just sit yhere and watch it you will see tje sevond core fires and shuts down alot.

Same for me (CPU 0 on, CPU1 off, most times) and I'll say I have noticed no real changes in functionality (speed, rendering, etc) or battery life...
I guess jury is still out or is this a YMMV kind of thing?
I installed system runner and watched the cpus. One was on and the other kicked in periodically
Mine said it was offline as well. Forced it on and am not noticing any difference in speed or temp.
Ill leave it like this to test it further.

As far as I know yes you must have super user permission to alter such system activities
I don't know why everyone is in such a rush to force the second core online, it turns on and off when it needs to.
So I installed system tuner from playstore and I'm looking at both cpu's and I noticed CPU 0 is running 100% of the time and CPU 1 is offline 99% of the time? I have this app on my galaxy nexus and CPU 0 and 1 would be online 100% of the time, so any of u guys wanna download that app and post ur results?? Or dose someone out there that nos more about the chips in this phone care to " school " me? ///my phone is rooted

It's the way that all dual core phones work to save battery. When using the phone heavily, both should kick on. While not doing anything or not processor heavy, just one core would run.

Correct.
CPU1 is rarely ever used. This is to conserve battery. It gets turned on/used only when there is a demand for extra processing power.
But some custom ROM/kernel combo's will change it so that CPU1 is used 100% of the time. I'd guess you had a custom kernel on your Nexus?

Thank u guys, This is what I figured, but I've never had stock rom and kernel on any of my other dual core phones this is longest I've ever had stock rom and kernel (4 days ; p) and had no idea CPU 1 is never really used cause yes most kernels take advantage of both, I turned on CPU 1 with the app but I don't think its working right, phone seems faster but I need run some tests ....thanks agn
htc one x+ stock 4.1.1 - 1.16.401.6
rooted
after all my lags ... tryd as u recommended to use cpu set and put my device on maximum cpu to try gaming...
the game play better in 20% but still have some lags (dead trigger)
and my cpu cant push to 1700mhz...
i did min 1700 and max 1700 on max proff... and cpu clock stick to 1600mhz...
maby i got failuer on cpu??
i did notice before that my battry draind very fast....
and battry and camera area get overheat very fast in games... !!overheat!!!! means that u almost cant move ur hands on the tuch cuz its make them stikky
and if i go to stteings>developer options >show cpu usege... i can see only 3 cores working and not 4.. as i shueld see...
(battrey save is off)
why im allwas stuck with the failur products ]=
]=
lol. You have me a nice little laugh.
DON'T put your phone at min 1700MHz. You will basically fry out the phone.
Also, why would you be going passed 1700MHz? The phone has a 1.7GHz processor. 1.7GHz = 1700MHz.
IF you want to go passed 1700MHz, you have to wait for a custom kernel that supports overclocking. Until then, you will not go passed the factory speed of 1700MHz.
MAKE SURE TO SET THE MIN BACK TO IT WAS!!! anything over 434 is practically useless. It'll just drain your battery, overheat the phone and fry your phone out, especially when min and max is at 1700MHz!
Oh yeah. If you use SetCPU, you have to choose "Set on Boot". But make sure you give it the right settings or your phone will bootloop.
the point is that i dont try to pass the 1700... but i cant reach him..... cant pass the 1600.... im not try to oc it...
its gets overheat with or without the cpuset ... and was like this from the moment i did unbox the phone...same as for the lags... (eaven in homescreen)
the battrey drain out eaven on low usege games... games that i did play on my iphone 3gs for 4-5 houers in and still had 30% left now drain my battry in 2-3 houers...
so much issues with stock normal phone somthing maby worng here dont u think?
and i bet for the hadware ... and not the software
for gaming first try the geming boost app (use search and you'll find it) this should fix most of your problems.
and further: don't set your CPU at constant maximum, this will eat your battery for breakfast.
keep the min/max values stock and if you still have lags in gaming you could try other governors with this app. but as i said... first try the gaming boost app, that really should do the trick
So you are saying your phone wont run at 1600mhz. How are you testing this? please explain in detail what software you are using and what test etc. I agree with the gaming booster app for gaming issue but it seems you are having greater issues. a 1700mhz phone should run at 1600mhz. We'll help you figure it out just need a little more info.

tested using cpuset... if i try to push it to 1700 he dosnt pass the 1600mhz just capped there....
100mhz diffrent is huge!!! not beacuse of the numbers... just beacuse its pointed about heavy issue... with electric or volt's failur or maby eaven failur cpu product
cpusets gets me 15% better gaming but still lag and somthims shatter
with game boost
almost the same ... a little bit smoother... but still dead trigger lag alot... and after 10min of gameplay its getting hot and the fps hard drop almost to slowmotion ...
shadowgun working good ...
gta 3 1.3 tegra moded work so bad and laggy still
dead trigger still lags
beach buggy blitz lags too (alot after 10min of gameplay)

Are you twelve and using a broken blackberry to type your messages? I hope you fry your phone and learn to use proper language next to me you spout off at the mouth. I'm sure your grandfather and "girlfriend" are very proud of your last statement.
Learn your hardware first and don't compare any tegra device to an iPhone 3Gs ever again. My brain almost exploded with the lack of undestandingn of the hardware on your part.

hi everyone,i flashed last build of lineage 14.1 on my redmi kate,everything went fine but after that i run a bench with antutu and cpux,they show cores 5 and 6 sleeping,don't know how to make then work,is it normal or maybe am i making a dumb question? thx in advance
Have you flashed/tempered with any kernels or kernel audiutor?

It's probably normal then. I am also using the same rom and core 5/core 6 are shown running at 0.0 KHz. Basically, the system automatically manages the state of those cores depending on cpu usage in order to save battery life.
Last two cores are the big cluster(high performance) cores which come online under more loads due to hot-plugging.
Try loading a video or a game and see whether these cores come online.
Hy guys.
My girfriend bought a beautiful S9 plus and she loves it. It is a great piece of hardware, from design to speed and camera. Just amazing.
Of course i had to test a few things myself (still a rooted note 3 owner). I tried my old "Nemesis", Retroarch, with a couple of games (3rd gen Cave shmups) that put to shame every smartphone Cpu sp far.
The games finally ran full speed, except for moments where a ton of stuff happends on screen and the framerate and audio start going a bit crazy. What is strange though, is the fact that the Cpu never goes beyond 1.7 ghz, never once, which is the little cores max frequency. I'd expect it to reach 2.7 which is the max for the big powerfull ones, to further smoothen the performance.
Is there something i'm missing here? There is no power saving activated and the game center(?forgot the actual.name) settings are set to performance (though from what i understand it only affects display, not Cpu).
...help?

I haven't gone beyond 1.7ghz since my last reset, I did when I first got the phone but my assumption is that s new kernel was installed that changed the way the CPU ramped up (Exynos btw) to counter the battery life claims. In all honesty from my limited knowledge it's probably the GPU that limits the frame rate but that's only a guess as 8 cores @ 1.7ghz is plenty of processing power.

The S9+ is not rooted, so it's on stock kernel.
Also, the emulator (mame) is designed to only use Cpu for 2d games, with Gpu used at minimum.
1.7 is far from enough, especially when it can go up to 2.7 to improve the otherwise non-optimal performance of the games. I'm very curious what's the issue here...

Yea mine is stock as well - my observation was that in the first month or so I had hit 2.7 a fair amount, but haven't in the last 2 months once so assuming they modified the stock kernel

Oh, now i understand. Well, it's very strange and frankly, a bit alarming. Could anyone else with up to date stock software share some numbers as well?
Same.
Same here on G965FXXU2BRG6.
Edit: It seems that CPU Spy doesn't work correctly on the S9. When using CPU-Z and running Geekbench 4, I can clearly see CPUs 4-7 running at 2704 MHz at times.
That's interesting. So my next test will have to involve Cpu-z as a monitoring tool. Thanks for the replies guys.
We need a cristal clear answer on this.

Ran Antutu on S9+ Snapdragon last night, it's being throttled down to a max. of 1.77MHz and no more even during antutu's 15 minutes Stress Test. It would score much higher if it was allowed to.

God damn it. Haven't got the time to do further testing myself yet, but by the looks of it 1.7 seems to be the max. and not 2.7.
Any rooted phones owners care to share some numbers? Can you lock it to 2.7 like it should?
Are we talking Exynos or Snapdragon here? That'd be a good piece of info while sharing the stats!
Personally i'm talking about exynos, but apparently snapdragon behaves the same.

Yes, i tried all settings including performance mode. It only affects brightness and screen resolution. The Cpu speed is still limited to a 1.7 max.

I did the same, then I tried in WQHD+ resolution hoping that it may create more demand from CPU/GPU and no, same 1.7. What is the best way to make a complaint about it to Samsung? We bought an 8 cylinder Maserati and after the honeymoon they remotely disabled two because the engine might blow?

Probably the official forums.
It would be great if a rooted user with a Cpu oriented kernel (overclocking, voltage, governor manipulation) would show us that those big cores can, at least when rooted, be used at full potential.

Thanks, am gonna register there, see what they have to say about it. That and my other question I'd have: why I received my 'new' S9+ with IMEI SV 07? And when I did IMEI lookup on line, found out that the phone was registered for warranty one month before I ordered it. My email to Customer Service was returned with "Samsung sells only brand new phones". Didn't know that there is no replacement policy at Samsung, you can only return it for refund, it's not a good option for me, because I took that 'bundle deal' and I don't owe the Chromebook anymore, they would subtract some$ from it. Well, according to Samsung, the warranty on my phone runs until October '19, we'll see.
