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.

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.

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 SetCPU today. Been testing the kernels ability to work underclocked at the max of 918mhz. Also set the scaling to conservative. After a days use it's been as good as normal full speed, 1512mhz
The battery lasted throughout the day, compared to my first two days of stock settings with only 6 hours of good use.
I'll keep playing. Still want to do some testing and benchmarks to make sure it's not under performing. But at least at the user level it seems to react the same.no lag.
I did confirm the clock speed out side of SetCPU using system panel.

Don't bother using benchmarks to rate a phones performance that is a fatal error there. Benchmarks never effectively rate a phones performance. I just go by how smooth the phone runs and it does it run everything I throw at it. If so gg pz end of story.

Well whatever works for you. Just saying Quadrant is a poor tool to use to bench for many reasons which I won't go over. Antutu is nice for SD speed testing I think, oter than that meh. Benches are just for numbers for people to flex their epeens with. They just really don't truly gauge a devices performance.

Benchmarks do have a some good uses... while comparing different phone models with benchmarks can be iffy, it can give an overall insight, (things like graphics capabilities with very GPU extensive games) but in the end user experience and daily use are the real judges.
Where benchmarks can be of the most use, is when comparing changes to the same phone model.
E.G. Comparing performance impacts of AOSP vs Sense, overclocking and under-clocking, and de-sensing/bloat removal.
When used for these reasons, you can get a really good feel for how changes are affecting your device overall. Even then, benchmarks are not the be all end all, and user experience is still important. As you may introduce lag or other performance issues that do not show up in benchmarks.
Which temp root method are you using? Mine isn't staying rooted long enough for me to justify using setCPU at all...
The new version and the one that comes with the newest clean tool stays until reboot.

Please let us know what settings you use that work for you.
I generally stay temprooted unless I'm going to be away from a charger for a bit and need BT (since you can't turn BT back on after temproot). I wouldn't have SetCPU autostart on boot (since it won't ever be able to get root access immediately after boot).
Meanwhile, I also set it to conservative and will see what that accomplishes.
A kernel needs to support setcpu, stock kernels do not. You need to flash a custom kernel, so you need a development phone or s-off.
Sent from my ADR6400L using XDA App
This kernel apparently does work with SetCPU. I've confirmed using other cpu monitoring apps that the clock speed changes are capped.
I own 7 android phones, and have been rooting, overclocking, undervolting each and every single one of them (well one I still cant get rooted). I know when the cpu is under clocked and when it is not. Been doing these tweaks for 4 years now. If you use a tool like System Panel, at stock settings you can see the max cpu around 1500 on our little bad boy. When it peaks out the clock speed is shown. When you under clock it, then check again it won't go beyond the max cpu set in my testing I put a ceiling at 918mhz. System Panel reported full CPU usage (100%) at clock speed 918mhz. Typically with stock kernels, your absolutely right, changes to SetCPU do nothing at all to the real cpu. Which is confirmed, when I reboot and dont have root, if I attempt to use SetCPU and make the changes, System Panel reports 1500mhz (roughly) at full load regardless of what I set it to in SetCPU. If I did this to any of my other phones with stock kernels, you are correct it makes no difference as SystemPanel reports the stock max setting.
No I'm not being mean or aggressive, just saying. =-) And no don't believe me, but test it yourself and confirm or prove me wrong some other way and I admit error. Either way, half the fun is messing with the phone and trying to get it to do things it should not do.

In my view, the "benchmarks" would be an OK measurement if you were comparing apples to apples.
I tried running both Linpack and Quadrant on the very recently and dearly departed Incredible right after a fresh reboot and having charged the battery overnight...when the thing should have been at it's freshest.
I got wildly different scores each time I ran it after a reboot...knowing that on both programs the scores would improve the more times you ran the test.
It didn't seem to me that either program was a reliable indicator of what my phone was capable of. I didn't even trust them to tell me whether something I'd done...cleared cache or deleted bloatware...had any real effect.
It simply boils down to how the phone feels. That's not scientific, but it works for me.

Linpack and Quadrant are not reliable benchmarks. TBH I don't take any of the benchmarks seriously, they are more for entertainment for me. But to each their own right?
Yeah some of the benchmark apps are a bit unreliable to say the least...
If I use one, I try to use ones that Anandtech uses. I trust them to find the better benchmark tools.
This morning I restarted my prime and im looking at system tuner pro...
All 4 cores are active and stuck on either 475mhz or 1.2mhz!
I didn't change anything...governer is interactive 102-1.6mhz limit....the cores wont turn off or scale down. It would usually scale down to 102mhz and turn off 2 cores...but they're all online...
FAST is good but it's killing my battery =P
Anyone know whats going on?
Pretty sire this is across the board for the most part. This happened after update to ICS or last update. Ive noticed it also but it scales to other frequencies also. Doesn't seem to effect battery too much. Your best bet if you worried about battery is to throw it in power savings mode in Asus quick settings. But no matter what mode its in, it seems to like to stay near maxed out. Maybe Asus adjusted the frequency timing to speed up things in ICS.
apologies
I'm sorry, I didn't see any other posts about this issue.
Thanks for your input
Yeah, I've had the same problem since the ICS update, but still can't find a solution, so I'm waitng for recovery and back to HC.. And, btw, it's killing my battery - it barely holds a whole day since then..
This seems like a plausible explanation for all the reboots people are seeing. With ICS the processor is kept in a more active state which uncovers wafer defects and heats up the SoC until it goes into protection mode.
Some processors handle the load better than others and it seems the spread is veeeery wide. nVidia is probably supplying Asus with parts from all bins, if they even bother to quality check and rate their parts after coming off the production lines.
I would argue that nVidia's thresholds for what is considered a passable Tegra 3 chip are way too low for real world applications.

Maybe. I can run overclocked to 1.6Ghz n still be fine no reboots. Like you said, not all chips exactly the same though. Small variances between all chips.
I'm hoping/assuming ASUS is aware of this, but just in case they're not, has anyone brought this to Gary's attention?

I'm sure they do know already. Probably amped the frequency timing up so ICS can stay as smooth as it is. It may get adjusted in new update we supposed to get any day now. New update "supposedly" fixes alot of issues.

Just took a look on system tuner, mine still scales down to 102Mhz. Not all 4 cores on all the time. It does like to stay in the higher range though alot. It all depends on what you doing and what you have running in background also.
mine used to scale down to 102mhz as well...and usually with the 3rd and 4th core offline
Odd that it has changed....
Thanks for all the input...im gonna try and see if manually updating to ICS will make any difference
*edit: I put the update file into the system root but TFP won't prompt/recognize the update...guess it won't make a difference....I'll try backing up then doing a factory reset
I'm seeing something a little different. Mine scales all over the place, except it barely ever hits 1300MHz or 1400MHz, even when set on Performance and gaming/benchmarking. For example, right now, mine only show 3 seconds on 1400MHz and 5 seconds on 1300MHz, out of 13 hours uptime.
I think ASUS and Nvidia have some work left to do in getting the Tegra 3 optimized. I'd really rather mine actually use its fastest stock speeds when in Performance mode.
Overclocking?

How did you get to overclock? I rooted mine, but had to return it because of problems. However, I couldn't overclock it either.

Seems like my i/o speed just got worse and now there's severe lag...

That's how its supposed to be. It doesn't run at top speed full time..lol your battery wouldn't lastlong at all if it did that. It only hit tops speeds when needed. Then it scales back when not needed anymore.
As far as your timing showing only a few seconds at top speed, all that means is you didn't do anything the prime needed top speeds for.
If you want to run at full speeds all the time I have your solution. If you rooted get System tuner app. Then open app up. Go to CPU tweaks. There it shows you what all 4 cores are running a piece in real time. The governor should be on default interactive mode. All you do it put governor on performance mode. Then raise your minimum speed up to the Max. Now your prime will be running at top speeds all the time. Now beware though, expect battery to drain alot faster.
I did that trick with my overclock n can have all 4 cores maxed out to 1.6Ghz at once. Battery drains faster than Asus performance mode though. As far as speeds go though, I can put my prime in stock powersavings mode, lowest power settings, n everything still moves fast n fluid. Same with heavy duty games also. There's nothing out on Android yet to really need overclocking power yet. PRIME handles anything you throw at it in stock settings. OVERCLOCKING is just for kicks really andbto make things that much faster. Not really needed. Overclocking will be better once bootloader unlocked and we get undervolting paired with overclocking. That way we can get great battery life and more power. Nothing wrong with overclocking though. I'd say if you not worried about battery life or gonna eventually be near a powersource, go for it. Android developement section of Prime. Its called VioerControl Mod. Very easy to install n setup. Works great. Everyone rooted should give it a whirl if you looking for more power or want to push the envelope.

My mistake. I'd forgotten that I'd rebooted since running the benchmarks and gaming, so my CPU Spy values didn't reflect them. I just ran some benchmarks and 1400MHz now shows 18 seconds while 1300MHz now shows 2:08 minutes.
I would still like to see that as running at 1400MHz throughout the benchmarks, so I stand by my statement that some additional tuning is required.

what Firmware specifically are you guys on????
I just downloaded system tuner... I'm running ICS, and my tablet has been rock solid (not a single reboot).
CPU0 is running around 200-400MHz, and the other 3 cores are offline (although core 1 comes online for a bit now and then.) And, my battery life is excellent.... same or better than it was with HC.
To clarify, those of you who are having reboots, are you all seeing all cores on and maxed out all the time?

On the contrary...ever since my tfp decided to keep all cores online and minimum 425mhz speed, I haven't had any lockups or reboots.
But my battery life sucks and my benchmark scores are Still horrible.
The disk I/0 speed is horrendous (as stated in the bonnie++ benchmark thread)

Hi everyone. I did some research on this topic but stil cant get an answer that helps me fully understand. I have seen the option to force all CPUs online on almost every device I have ever had, but it somehow baffles me. I currently have a Galaxy Nexus and a new Transfomer Prime both running AOKP. When I look in System Tuner Pro, I can see that only 1 core is active. On the G Nexus it doesnt bother me that much to see only 1 running, but on the Prime, it does seem kind of strange that only 1 of the 4 cores is running. There is an option to force all cpus online, and Im wondering if its a good idea or not?
I wonder why the option is off to begin with? Whats the point of having multiple cores if only one is active? Are there any advantages/disadvantages to forcing them all online? Will they come on automatically when running graphic intensive applications, or will they always stay off if I dont turn them on?
Im on my 7th Android device and have always wondered about this, but having my first quad core device has really made me wonder even more.
Can anyone help me out with these questions? I would love some clarity on how exactly this works.

its actually very simple as I've described it in detail in various threads. what reason should you have for it? there is nothing THST even remotely requires that much power. so what use would it be other than burn battery up extra fast.
more than one core activates. Prime governor by default is set to On Demand. so when it needs the extra power, it'll cut on multiple cores. when it doesn't need the power, it conserves battery. you will be surprised how fast n smooth things run even on battery savings mode @ 1Ghz.
If you really interested in burning up your battery and heating up the prime CPU faster than normal, let me know. lol. ill tell you how to make all cores active BUT they will be maxed out at whatever top speed you running at/whatever power mode you on. Curiosity killed the cat ya know..lmao
actually you need to read this PDF file attached to get a better understanding of how tegra3 and mulitple cores work. its attached to this post. first one is tegra3 whitepages. most detailed info you will find on how tegra3 works. then 2nd one is whitepages on multicore cpu's and how they operate.

I was looking stuff up on that today. The highest I could find documented was 1900 on the cpu and 800 on the gpu.
For everyday usage, overclocking is useless, even for gaming. Undervolting can be beneficial, but from what I've seen, the latest processors get approximately the same battery life on stock voltage as they do undervolted.

I just like to play around with different kernels but the kernel I was using def made the device snappier and I had some killer benchmarks! But you are right though! Custom kernels on this device is not really necessary...
I plan on building a custom kernel then, hopefully tomorrow night or possibly Saturday. I do have some plans to improve it, but nothing related to the CPU or GPU going faster, just having other stuff operate better and getting rid of anything not needed.

1800 is a VERY good starting point.... I ran a kernel when I had the International variant and it was FAST!! I think it was called "Bullet" kernel...?

I hope I don't get another lemon CPU... my TBolt's would only overclock to 1.4G, anything above and it locked up.

That's better than me. I could run 1200 for weeks but at 1400 about every other day it would restart randomly.

HA. My TBolt stayed stable at 1200, but ANYTHING higher than that and it would crap out on me.
I could run my bolt stable at 1700 all day. Kept it at 14 for a month no issues. Stayed at 13 the rest of the time. Course at 17 it was like it was running on a watch battery with the amount of time it would last. Lol
Eh I ran 1.6Ghz on my Thunderbolt 24/7 and with the 2750mah battery it lasted me days.
On a phone like that there was a significant improvement to the end user that justified the overclock. Now on the Note 2 I'd expect there to be very few who would want an overclock at all. I am part of the very few however. I play a lot of emulators on my phone and for N64 and Playstation I need all the raw CPU power I can get. Yep, even on this beast of a phone I still get some lag and stuttering on those emulators. The reason being is the same as PC gaming. AMD thinks that by adding more and more cores to their processors they can win the performance arena. Unfortunately they are wrong. Intel has the right idea, 4 cores is plenty now let's improve the efficiency and performance of those specific cores.
Same goes for our phones. Quad core is the most I'd ever want in my computers, anymore is just a waste. Now let's get better architecture for the processor to maximize clock-for-clock performance. And overclocking those cores helps it in apps that don't support more than one or two cores, because the baseline performance for each core is boosted.
So yeah, can't wait for a 1.8Ghz kernel
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.
...an error, please remove.

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.

Post#9 was about Snapdragon
Has anyone tried hitting the "Performance mode" toggle in the drop down menu? Stupid question, but easily overlooked.

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.
