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

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 ?

that 's 3 people with the same problem...and no one is helping -.-, ^^^and he 's on v10H so its not fixed by update .-.

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

Hi guys. I looking forward to ROM with can work at 1.2GHz. I think most of XDA users have modified ROM working at 1.2GHz, so everything fine? It's save to run Galxy Tab at 1.2GHz?
1.2 has been stable for me for well over a month now. I run 1.4 from time to time when I want to play games or just show off. Some tabs report overheating, but use setCPU profiles to alert you if that happens and you wont run into any problems. I have setCPU to warn me at 40 degrees and at 41 it goes down to 800mhz. Just keep your eyes on the temperature to be safe.
Its a popular misconception that the tab runs at overclock frequency ALL THE time. Unless the kernel (which I seriously doubt coz that would be stupid) is programmed to run at maximum clock frequency or you have set it up yourself (with setCPU or voltage control or w/e overclocking utility you use) which is basically an explosion waiting to happen (or at least crash). The tab runs at a RANGE of frequencies it runs at max frequency (1.2 or 1.4) on demand like playing a game or an HD movie or anything stressful.

You want to say, like PC CPU, that Tab ARM Cortex A8 chip working on range of frequencies? It's possible because of battery save, but I think Tab's Cortex A8 is designed to work at 1GHz all the time without any problems.

DarkPal is right.
While you're theoretically correct too, in the sense that the Tab's Hummingbird is designed to be able to work at 1Ghz all the time, by why would you want to do that? It'll kill your battery if you set it to run at 1Ghz all the time, much less at the higher frequencies that these CPU were not rated to run. Not to mention the heat issues.
There's a reason these ARM-based chips scale up and down the frequency scale according to the CPU governors' settings and load demand, and that's why ARM-based chips are known for their battery savings.
galaxy tab 4G Lte runs at 1.2Ghz
http://www.gsmarena.com/samsung_galaxy_tab_4g_lte-3769.php
I've been running mine at 1.4 for about a month now but undervolted too. Perfectly stable. If you are using SetCPU app you'll be able to see how much time your tab spends at each level.

Bit of a noob question but apart from games in what other areas does overclocking help?
I notice the difference with video. Crisper and smoother. It's not a big thing, but why not do it if you can?

Because it does run your battery faster and hotter, as well as the processor itself...
Force a sprinter to run 5 miles, they can do it, but I bet they tear something along the way...
Oh yeah, thanks to the illustrious Rotohammer that's not a problem...
Ever since I upgraded to Roto's JMI ROM and a few other tweaks [ see my post: http://forum.xda-developers.com/showthread.php?p=12786456*** Galaxy Tab Master Tweak Thread*** ] the battery life on the galaxy tab has been absolutely insane. Even though the phone is overclocked to 1.4 Mhz.
I used to come home at the end of the day (before overclocking) and my battery would be approximately 15 percent, now it's always over 50 percent. I don't know what the black magic is, but it is good...

Hello, Im new in Note, installed yesterday Slim Bean Rom and hydracorenirvana v7 OC kernel and I noticed that Note get warm, like 35-50 C while browsing internet or doing some low requerements stuff. I tried to low CPU to 1ghz but still the same... And while playing it jumps more then 50C, is that normal? I really dont want to burn it
Probably the media scanner is maxing the CPU, normal after installing a new ROM especially if you have a lot of files. Give it some time to settle down.

Dont forget the Hydracore is a maxed out performance kernel, designed for ultimate speed, so it will generate more heat doing basic things unlike the stock kernel.
and not to mention the massive power hungry screen and huge battery inside, its normal so dont worry about it. If it gets to the point where its too hot to touch, just remove the battery for 10mins and allow it to cool down.
Can I OC and UV GPU with hydracore kernel? I have S2 with dorimanx kernel , there is Stweaks app its very usefull when I can choose battery or performance profiles. and its auto OC and UV on that kernel. Can we get something on Note?
there are many apps that can do this, Tegrak, SetCPU etc, but be careful messing with voltages as it can prevent the phone from functioning.
You can use a basic app such as no-frills-CPU to adjust OC and governors.

Yes, I know setcpu, but I want OC / UV GPU not CPU. On my S2 via STweaks I can OC/UV also GPU.
Ok, now Im on jellybam woth "voldemort" kernel and on battery it looks little less warmer but when I charging and try to play games or browse it gets really hot, like ~55C . Is it normal and not damage my Note? Also I always use 1ghz cpu speed. with 1.4 or 1.6 ghz its little bit warmer

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.

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 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.

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.

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.
Hello people! I just succeded with rooting my LG Optimus 4X HD :victory: And the reason I did that was to increase the performance on my phone, but I couldn't find any good apps for that. I want suggestions about apps that can overclock EVERY CORE and not just a single one, please respond as soon as possible

have u done any overclocking in your whole life ? ...
you cant overclock from settings only one core. to overclock only one core u have to do a surgery to the cpu chip........
u cant overlock if the kernel does not support it. stock rom limit is 1500

Dude I just rooted my phone like 2 days ago so don't excpect me to be a pro at these stuff xD (I am a noob) But you didn't really answer my question tho :s
First,You need to install a kernel that supports overclocking, and after that you can use app like trickstermod or tegra overclock. But i would strongly suggest you to read more about rom,kernel,recovery etc. before asking such questions.

the phone doesnt have to do anything with the procedure u can overclock anything. from just a coffee machine to a kitchen , from a pc to a phone !! if a cpu has more than one core, u cant just overclock only one of them. I answered i told u the limit of the stock rom and kernel is 1500. u cant overclock. u must have a custom kernel that can support overclocking.
that means u need to unlock bootloader and flash at least a custom kernel if not a whole rom.
<<EDIT>> and just for the knowledge ! take for example samsung s3. it has a lower cpu frequency but the phone is little faster than our optimus. overclocking isnt only about rising the frequency. u can also overclock by slightly giving more voltage and faster correspondence. u have to read a lot to understand how it works. for example a mistake can make u have a slow 1700 cpu but a fast 1200 cpu. read read read read

I get it now, but I think I asked the question in a wrong way so let me tell you again how I was ACTUALLY thinking. What I want is to enable EVERY single core and make them have 1.5 GHz speed. How can I do that?

Buy tegra overclock from playstore.

set governor to performance, set cpuquiet to userspace. you need trickstermod app & custom kernel in order to tune this.

And watch your battery drain in under an hour.
What have you been doing to actually have a point that you have thought a quad core 1.5ghz phone needs overclocking?

your cores are already at 1500. to set a perfomance governor to make them run permanently at 1500 will cause u a huge battery drain and cpu overheat. when u will go play a game the heat will enable automatically the cpu to rest so u will have actually around 1000 mhz speed. the cpu HAS to rest. the phones dont have many big fans inside to cool the board and the cpu. thats why people prefer ondemand governor usually. the cpu rests until the 1st core go to 90% usage or more and then the other cores are enabled too. when the cpu usage go below 90% one core is working again and when there isnt any need for cpu usage , the core goes down to 102 mhz.
overclocking
before you get your phone overclocked you should but in consideration that you may break your phone..over heating .... battery consumption.. don't look for performance alone >> you cant get performance with out battery drain or over heating >> just thing before you do that
You should look at how often cores 3&4 are even active. It's very rarely on my Nexus

ah c'mon he cant destroy the phone even if he wanted to. its not like he has the knowledge to decompile the kernel , change the proccessor limit to over 1700 and recompile it. so his limit is 1700 of iodak and werewolf and mokee. the thing is to understand how overclock works. he will figure it out eventually.

LOL... How can we decomplie the kernel and recompile that?

Yeah, I think the max over clock for p880 only reach 1700. Or am I wrong?

for the developers that know what to do , max for our phone is 1700. originally the safe overclocking at any cpu since many many years , is around 20%. after that it needs cooler. the better the cooler the more u can overclock.
Hi, trickster show me that my phone don't use the 1700 MHz. Y?
Sent from my LG-P880 using xda app-developers app
Probably it is not overclocked.
The stock higher operating frequency of p880 is 1500 MHz, and that is what your trickster diagram is showing.
So. Either your phone is notoverclocked, or in whatever kernel you are using maximum frequency is set to 1500 MHz.

Ehm, i have iodak v08 cm10.1.3 and cwm6.0.4.4
I'll check how to overclock the CPU.
May some one also look for a how-to if i don't find anything for overclocking my CPU
Thanks and kind regards
Edit;;;
I've found it. Can some one explain to me how to fit this things?
