i m on v10D, i just rooted and intalled setcpu, 1500 max 1400 min gov: performance, now just after i restart/turn on my device, the frequency is right..but then after a couple of minutes it drops to 1000 mhz..i have 2 questions:1.is there a way to fix this,2.does any other version( other than v10D )offer better gaming experience...and if so, which is the best?
Thanks for your time :good:
Well i have mine when I game set to 1500 low and high plus performance. It never drops and other then that. One issue I did encounter is that as long u have profiles set up and checked it will still use them regardless if u set it in the front page to a certain speed. So u need to uncheck all profiles and also uncheck the use profiles. Basically uncheck it all then even if u uncheck use profile it still will use the profile if u select one. Here a picture from what I mean. See how I unchecked everything. U need to do this to or it still will the profiles even if not checked the use profile box.

not that i know of..i had lg gear box but i removed it...i also have ATP tweak but i dont think that s relevant
Edit: i just removed the atp tweak..and it still automatically returns to 1000mhz
btw, are you facing any lags, framedrops, etc on v10F?
and is there any way to force the 4 cores to work simultaneously?
I have the same problem. When i set frequencies to 1500 min and max in game it's still change to lower.
I don't really know. Mine always stays steady on 1500

CPU not run full speed
Hy !
Merry Christmas !
My problem is same as you. I don't rooted my phone.
I have stock v10h firmware hungarian,
When I play games, all games very laggy.
I checked the CPU speeds, the max frequency is 1300Mhz and below.
What is this ? Tegra 3 stupidity ?

Just write 3845#*880# and on the bottom you can see cpu usage, turn it on and play some game.

that 's 3 people with the same problem...and no one is helping -.-, ^^^and he 's on v10H so its not fixed by update .-.
anyone??
It didn't change anything for me to put the CPU @ 1,5GHz constantly. I did a test with the game Horn and its lagging exactly as with the default CPU governor enabled.
If you think about it for a moment, it makes sense, as the GPU is doing the majority of work.
Tegra 3 CPU Clocks
Based on what I understand about Tegra 3 from this thread- http://forum.xda-developers.com/showthread.php?t=1664391, the CPU has 3 different "modes". 1.5Ghz single core, 1.4Ghz dual and triple core, and 1.2Ghz quad core (At a certain temperature, remains on 1.4Ghz or 1.3Ghz until that temperature is reached... quickly). The reason why the frequencies go down is because when the phone is utilising more cores, the frequency drops too. The move from 1.5Ghz to 1.4Ghz causes lag in games at times, which is why the maximum should be set to 1.4Ghz to prevent this from occuring. Also they said that the performance governor causes 2 of the 4 cores to no longer be in use, which is NOT good for Tegra games such as ShadowGun as all 4 cores cannot be used, so they advised people only to use it for Non-Tegra games as they do not use all the cores. Hoped I helped in any way, even though I'm a new guy. I'm not sure if this applies for ALL Tegra 3 devices or just the HTC One X, but it still looks like useful information.

Thanks for your reply..but for me, the frequency doesnt drop to any of the values above, it automatically drops to1000 and mostly its on 1 core
Which brings me to another problem...i need a way to force the activation of the 4 cores simultaneously...in most games the cpu is stuck at 100% single or dual core

Most games are not optimised to use 4 cores, so I guess using only 1 or 2 cores should be normal. What governor are you using for games, because this might have an effect on the performance.

I tried all governors..performance isnt the best, idk why..userspace seems to work fine, but still when i set min and max freq above 1000mhz, it automatically drops to 1000mhz ._. and that isnt quite good for gaming, and since i bought this device over s3 for gaming, i feel f*cked
so would an update to v10F or a hard reset fix anything??
EDIT: and there 's 4 other people with the same problem and one of them has v10F so hardware problem??if so, im hanging myself
Hello guys,
I`ve been trying to find a way to have all 4 cpu cores online all the time to see if it helps playing games (lag) as I tested, for me every game lags when there is only 1 core running, than when the phone needs more power it turns on other cores and it lags, on that exact moment!
Trying Glowball, Tegra 3 game doesn`t lag because every core is on 100% of the time! And I`ve seen users saying that they don`t have lag on their phones because every core is active during gaming sessions, which is not my case.
I tried to use System Tuner Pro > Boot Settings > Force all CPUs online with no success and didn`t try CPU Editor as I don`t know how to install it.:silly:
If you have lags on gaming this might be a solution!
Does anyone know how to keep`em online all the time? 10H here.
Thanks for your help. :fingers-crossed:

Well Glowball doesnt lag because they optimized it for a tegra3 devices. so the problem is the game developer, not the phone as far as i know.
i dont know if what you want can be done.

Well, Shadowgun THD is in theory optimized and lags anyway. It`s just frustrating to have a quad-core high end phone that lags on so many games.

I am playing Shadowgun THD without lag I dont know why, But yes u are right about this problem.
I have tried playing most wanted It iagged but I noticed that the procesor speed are 520 mhz or such, and it makes problems,
So I put maximum 1500 MHz as minimum speed clock, but after playing more then 5 minutes processor speed was not more than 1000 MHz (even with root setup).
It turns that the problem is in the kernel, it is some sort of OVERHEATING protection.
But I am pretty sure that all 4 cores were active even the speeds didn't go more than 1000 MHz.

its not a overheating problem. i play MW and theres is alwasy only 1 core at 1500MHZ at 95%. If the game could use the other cores, it wouldnt.
remember htc has exactly the same problem... its the developer fault coz there is apps and game optimized t use all cores when needed
This sucks right? If this could be done I`m quite sure that the lag problem would be solved or minimized greatly!
If anyone knows something about it please let us know!
Much appreciated.
First if you forced all the cores online ,, then you can use your phone for about 2 hours with overheat . So you will lose your battery .
and about the games it is a problem with our ''kernel'' ,, the kernel is controlling the cpu and the hardware . LG optimized the kernel for long battery use and if you noticed the cpu takes a long time to change the frequency . LG made the phone for daily use .
To test CPU use benchmark ,, not games , games are very complex application and maybe isn't compatible with tegra 3 .
Our phones have nearly the same Galaxy S3 benchmark scores .
And if you noticed our CPU is excellent with miltitasking
you can say our CPU has a hidden power .
Any custom kernel can solve this problems but we have a locked bootloader . So we should wait until JB which has unlocked bootloaders (as LG said)
Trust me, making an app that can even run on more than one thread is hard; very hard

i have that exact same problem and it IS caused by overheating..when temperature goes over 36c the max speed automatically resets to 1000mhz if the min speed was above..but when temperature is below most games work flawlessly

I only faced game lag issue when my device is over heated or when playing multiplayer games (like SG DeadZone) with bad internet connection..never faced such issue due to CPU?
To overcome heat issue I have underclock max speed to 1.2ghz with CPU Tweak app..and it has helped a lot with over heating as well as battery life, and never faced any issue with lag even with 1.2ghz speed..
I have read in many place that even HTC One X behave similarly until JB updates arrived so you dont worry much even if some configuration or app in your device is creating game lags, it will be much better with new JB updates :fingers-crossed:
Quick note:
The Tegra 3 can run only in Single Core mode on 1.5GHz, in other words when your CPU reads 1.5GHz, only one CPU core is being utilised. If you actually want to use all 4 cores, you should set the max frequency to 1.4GHz to avoid the CPU clocking up to 1.5GHz. Lag is caused by switching between all 4 cores on 1.4GHz and single core on 1.5GHz.
I cannot set the max cpu speed. Tried different apps, iam on stock rom v10h, with root, new on p880

actually hardware wise tegra 3 is capable of running all 4 cores at 1.5ghz however almost all of current android app are not optimised for multicore cpu..however i have noticed when monitered using apps that it somerimes uses all 4 cores at 1.5ghz.
However its better this way if its not running all 4cores at full speed...infact i have underclocked mine to 1.2ghz this helps alot to over come heating issue as well as battery life and no issues with HD games :thumbup:

I'm referring to the Tegra 3 T30 present in our devices. The T33 in the HOX+ can run at 1.6GHz in quad core and 1.7GHz in single core. However, the T30 can only run at 1.5GHz single core and 1.4GHz quad core.
To cite Wikipedia,
Tegra 3 T30: 1.4 GHz Quad-core ARM Cortex-A9 (up to 1.5 GHz in single-core mode)
IIRC over at the HOX forums there was a thread on CPU management to prevent lag spikes in games when Tegra 3 switches from quad core 1.4GHz to 1.5GHz single core or something along the lines of that.

This app is getting famous now, but in case you didn`t see, it`s called tegra overclock (not tegrak!) and it manages to force every core online pretty well. It has some good other features too.
It`s paid but it`s worth it.
not to mention it DOES improve your gaming experience.

I don't know if anyone have installed CPU Z in you Xperia Z
but any of you have the same problem as me.
in CPU Z, 4 core of CPU is displayed, but 3 of them is showing status of stopped. (some time the stopped core will show the clock speed)
Is this normal? if no, then what can i do.
I think that the four cores dont work all the time, it starts using them only when neede, my cpuz app shows the same as urs. Thats normal.

This is fully normal, because while you are at CPUZ, there is no CPU usage, so your cores are off for power saving

since what i remember is clock speed is not related to loading... even CPU not in use, the clock speed should still able to be extracted

Qualcoms cores are asynchronous. Each core kick-in when needed and most important they work asynchronously.
You can see this sort of behaviour on any device. Qualcomm CPUs run asynchronously, that is, the different CPU cores can turn on and off independently of each other, but more importantly can clock themselves independently of each other as well, which other manufacturers don't do. Seeing 1 core on and 3 cores off can be on any quad core device, but seeing one core running at 1.5GHz, another at 384MHz, another at 1GHz and the last one off is a Qualcomm only feature. Supposedly helps save battery life since clocking asynchronously gives the CPU only the power it needs, rather than clocking all 4 cores to 1.5GHz when 2 cores are at full load and 2 cores at half load (for example).
My Samsung Exynos Note 2 also runs 3 cores and stops the fourth. Seen in CPU-Z. I came here because i found it weird it stops the 3rd core and not the 4th. It's not a big deal I was just curious why it chooses to stop that core. My cores also clock independantly.
How many cores (not cpu) does a htc one have? It's has 4 cpus I know that, so what about the gpu? And the HTC one has an image processor, so does that make it 6 cores. Like the Moto x has 8 cores. 2 cpus, 4 gpus, 1 natural language processor and 1 contextual computing processor. So can you tell me from this explanation how many cores a HTC one actually has

Until yesterday, i was an Xperia SP user but today i move on Xperia Z.
Now i'm on 4.3, i' not sure why i get better benchmark score with SP(antutu- 23500+) but with Xperia Z(antutu- 20000) even Xperia Z has a Quad Core Processor, 2GB RAM & Same GPU.
Can anyone please explain that.
Thanks in advance.
Mainly because the SP has a 720p display compared to the Z's 1080p, therefore there is less strain on the GPU during certain parts of the benchmark.

This.
Try it on your computer if you're still confused about it - set resolution lower, benchmark, set higher, benchmark, compare.
Also, consider the fact that the dual core processor in the SP is clocked faster than the XZ. So in single threaded apps/benchmarks it will most likely outperform the quadcore as the extra cores aren't being utilized.
The majority of apps out there are single threaded so it's possible that antutu's tests favor single threaded apps? This is just speculation though.
