I've been playing around with System Tuner since it came installed on Flappajaxx stock rom. Just noticed that in the CPU section, it shows CPU0 and CPU1. CPU1 is showing as offline though. Does that mean one of the cores isn't being used?
Yes. It comes online when needed.

Agreed...and "do not" force both cores online...
As mentioned above, the Second core will come online as needed under high load conditions.
If you force both cores online, your battery will evaporate, and your CPU temps will increase by nearly 30%...
I went down this road a week or so ago, and it didnt end well...LOL
Gotcha...good to know.
It does come on as need but it also depends on the users phone and what's running on the phone. I've had both cpus running non stop through system tuner and had no problem with heat and little drain. Again its the user and their phone so best bet is to leave the other one off until needed.

Hey all just curious. On some kernels I see it allows me to adjust the values and save them upon reboot. Im trying different sampling rates and might have a decent set up if anyone wanted to try it to save battery. I came across a nice write up somewhere ill link up later when im on a computer that inspired my testing.

ya its overclocking its nice makes the phone fast
Maybe I dont understand im talking about the advanced tab. It allows to manipulate the scheduling of the cpu. As I understand it the lower the sampling rate the more often in a second the cpu runs its tasks. So by raising that number the cpu isnt constantly running the same tasks as uselessly. This is my rough understanding and my juice plotter results are substantiating my claims.

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.

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?

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.
Just ran system tune in my phone and it had one processor offline.. I've tried like all the uclf6 roms and they all ran laggy.... I used system tune to bring the one processor back on but why would it start offline???... Any sudgestions?

I am running Milestone 6 . And to see what you were talking about I downloaded system tuner and low and behold mine says that CPU01 (or something) is offline. And then it would bounce to 384mhz and then offline again. That's weird. But just wanted to show that you're not the only one but that's kinda the only way I can help you. Best of luck
As means of reducing battery consumption, it'll kill off and re-enable the second core as needed for the load.
Saved and Texan by the Grace of God, Redneck by choice.
Don't worry, it's working. The core is turned off and on depending on the load.
The best way to confirm this is to run Linpack for Android. If you run the single threaded and the multithreaded tested, you'll see almost double the score in the multithreaded version.
Thnx for the replys just wanted to know if i was the only one... I forced it to keep both on the phone ran super smooth for like half a day but battery life sucked. ... Took it back offline to let android control it. ...

I'm on my 2nd refurb in a week..the 1st ,the proximity sensor did not work..and now..using aokp my quadrant scores are like 2100..thats not any faster than the wife's Droid 2..that being said on orig rezound I was scoring around 3200..if any 1 can turn me onto a way of checking my 2nd core I would be plzed
System tuner from the app store. Although the second core only comes online when it's needed. You can force it online but all that will do is shorten your battery life.
Never trust benchmarks, especially when your wife's phone is different. My wife's phone has a higher score for graphics than my rezound, but that's because the Rezound has a lot more pixels to draw on account of its 720p screen

You need to be careful which app you use with the stock kernel, they can cause issues with perflock just trying to monitor the cores.

Hello,
I have tested the app from the playstore "Tegra Overclock" (the app needs root!!!) with my HOX+ and I'm very impressed.
https://play.google.com/store/apps/details?id=com.tegraoverclock&hl=de
The micro lags, especially in 2D games, comes from the GPU.
The GPU is locked to the clock of the CPU.
When the CPU has a lower clock, the GPU also has it and that is the reason for the lags.
I tested it with the game "Rayman" and I could eliminate 95% of the lags.
The only thing what i have done is to set the GPU clock with the app in 3D to 520MHZ and in 2D (to the half) to 260 MHZ, so they aren't locked to the CPU clock anymore.
I want to share and to discuss the experiences with the HOX+ between the users with this app to share and to find out the best settings.
Does some one has other configs which are more battery friendly (and are also eliminating lags) ?
I think, that the micro lags in games like Rayman and TempleRun2 and so on are a big disadvantage of the HOX+ and the app helps us in an easy way and without a custom kernel or custom rom to eliminate micro lags.
Which tegra overclock? Could you provide a links?

What is the best settings for gaming and some battery with this app? Doesn't seem to work for cpu clock. I set max and tegra cap both at 17 and min at 10, hit apply and also check apply on boot. Close the app and open it again and the min and max are both at 17, obviously doesn't save the settings. This is what I've noticed so far with this paid app. I play sushi chop and it runs flawless, zero lag now. Never really lagged before but sometimes choppy, not anymore. I have you settings at gaming normal think its like 328mhz and have 2d settings the same. This setting seems to stick after closing the app and also on boot. I have master boot checked so these should all take effect on boot.

I only made the settings i described and my battery consumption seems to be good when i want to save battery, i tick the HTC stock energy save mode to max the CPU to 1,3 ghz.
I think that the CPU settings are saved, you will notice it when you try 1,5ghz as max for example.
Only the values in the choose-box doesn't show the actual settings...

You are probably using ondemand governor! if you wish that settings applied by you remain same then choose interactive or conservative. The problem is not of our app but its due to crippled ondemand governor that takes its own decisions.

You're right, I have on demand. I understand the app description in the market place says its newb proof but guess not as I don't even know what on demand, interactive, conservative, etc mean to the end user. I hit legend on each page to learn but on some pages such as this one in the app it can be very vague at best at explaining the options. Guess ill try interactive even though I have no idea the difference between that and conservative.

Guess you are right, never thought actually a person who can root necessarily know these terms. We will surely add some Real world examples to make it simpler to understand :angel:
We will add some homebrewed profiles based on user feedbacks to help new users who knows less in this regards.
For now its best explained as :
Consider your phone Cpu as a hotel and a governor is kind of its manager, obviously if you choose wrong person to manage then you loose earnings. In smartphone regards choosing wrong governor can lead to unbalanced performance/battery(as its equally valuable to money here!).
Now we don't wish to drag you in every governor details for now, just cut the talk and check if changing governors solve your problem and as a piece of advice DO NOT CHOOSE OTHER THAN Interactive, conservative, ondemand.

Update
Just ran Epic Citadal benchmark again on battery save mode using lateset elegancia colored Rom and after using this app and now getting worse ever FPS benchmark of 36! WTF?
I've attached photos of the only changes I've made using this app. I again set min cpu to 96000 while on battery save mode but again as u can see it never saves the settings or at least doesn't display the setting is saved as seeing above in the picture below, has all settings at 1.3ghz and using interactive as instructed and of course hit apply.
What boggles my mind though is I'm noticing games actually working better where they use to be choppy on battery save mode, now not choppy.
Just to use as reference before using this app. Using the Rom I stated I would on average on battery save mode get a benchmark of 47-48fps. Without battery save I would get on average 52-54fps. Now my fps on battery save is around 36 and without battery save is around 41.

First try to solve the frequencies not sticking with conservative governor now... Second Go to FPS section and enter value 0 and hit apply twice after that reboot(normal reboot not the quick one)! this will reset any settings you made, as your benchmarks shows you are limiting FPS. Now check again and please report. Also you get reduced choppyness because you are still getting FPS in range 30-40 in games.
There is one secret : When you are playing game and getting 50-60 FPS and suddenly a complex scene arrives and lower this to nearly 30FPS this although is above 30 FPS but our eyes can notice the difference (The transistion from say 60 to 35) and hence we feel like something is lagging. When you set the FPS to 45 then this transitions results in lags that are difficult to notice

Ok a little better now. So are you saying that interactive governor is not sticking my frequencies? This is what i had and the app shows different frequencies than what I set when I back out of the cpu option and go back in like I did nothing.
Well I changed governor now to conservative (frequencies still don't stick when u back out of cpu option and go back in) and I changed fps to 0 and apply twice and full reset as instructed.
Good news is that now epic Citadal benchmark brought my fps on battery save mode to 46.8 which is basically what it was before installing ur app so I guess all in all no real change in this regard unless I'm missing something? Thought the whole reason of fps setting is to have constant 60fps if set to this, not fluctuating?
Thank you and really appreciate your help in this. This is all new to me. just trying to take full advantage of this device mainly for gaming as I like to game a lot.
Basically why I bought this device as it was falsely advertised at the time of its release as one of the best gaming devices on the market for mobile. Guess the fine print never said that is not the case for gameloft games (or really any game that isn't tegra optimized which is only a handful at best) and that u can only game for 20min intervals before the battery goes down by 35% and feels like its going to explode from heat!

The frequencies stick only if you put both the min and max at the same frequency as specified in the legend

Understood. Many people who purchased a phone/tab having Tegra 3 wished to play games.
First we would like to make it very clear that the frequency save problem is not a bug of our app but for some reasons the settings never stick. And it do not require you to have min and max the same! You will lose the battery very quickly..
Second thing is that FPS section is for limiting FPS in everything. For example if you are getting 46 FPS in benchmark then if you limit FPS to 40 then you will get max 40! But reverse is not true as you wished. FPS (Frames Per Second) is dependent on harware capability + Software complexity. A powerful hardware + least complex software produces higher FPS and reverse produces lower FPS.
At the time Tegra 3 was really powerful as no other company had a quad core device + a good GPU. The problem is competing phones were running at 960*540 resolution and Tegra has to run games on 1280*720 Resolution! The math is if you increase the overall pixels the you inturn increase the load too. But all tegra devices comes with this 1280*720 or higher resolution and there it has to work harder and hence the battery is lesser than other competing companies! The other bad thing with Tegra 3 was 40nm Fab technology (won't bore you with this stuff but the less this number is the better) and it was a quad core+ it was using an older architecture while the competitors launched their products later on with better architecture and 28nm Fab and hence thats the end of the Tegra Story
Battery can be preserved friend if you choose the frequencies and brightness of device smartly. lets say when you are pleased with 40% brightness then why go 100% and if you can run games smoothly at 1Ghz then why 1.7Ghz?

Just apply max and tegra cap at 1.7 if that is your wish and minimum frequency to 51(lowest) the system may show it 500 or so but at times it will get set too.
