T520 CPU temp with CM ROM hotter than with stock? - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

I have installed CM nightlies from @crpalmer in my T-520 some days ago (now 20140915) and i think the device is hotter than with stock ROM. I have installed CPU temp and when i use Chrome or any app it's 50ºC (122F) and when I play games (Brave Frontier RPG) i have 76ºC (169F). I'm not sure because i have no measures from stock but it looks like hotter than with stock ROM. With No-frills i have limited CPU at 1,0GHz but with the same results so I think it could be some problem with GPU settings. Could be a CM bug?

T520 cpu overheating
Was there ever a resolution to this problem? I seem to have a similar issue and despite a lot of googling and searching through this forum I do not see a conclusive answer.

[Q] OC problem

i've heard some people can OC their GIO to 921MHz stable, but on my gio it can't even get stable on 883Mhz. on 864MHz is somewhat stable but i still get hung or FC randomly, im super stable at 844MHz.
Why does my phone can't be OC like them other guys?
Not all devices are made exactly the same. Processors can behave differently as do the batteries and other hardware.

is there nothing i can do? i've tried many ROMS, on some i can get to 921 for a few seconds, but still the same. will changing kernel help?
Why not stop overclocking ? Just find a very fast rom and then you can save the overclocking , hence the instability and hotness and draining battery. That way you will have longer life on your Gio.
L.E. : just change the minimum frequency to 245 and refrain from using roms that are heavy right now , like CM 10.1 , try anything based on gingerbread like Adrenaline or Enhanced 2.3.6 or DebianDroid for example , or AOSP ICS wich i find very fast.

well currently im using AOKP milestone 6 CM9 based, i use conservative governor 245-844MHz, installed adrenaline engine 4.4, and pim my rom and set my OOM and LMK to medium settings. battery is drained only when im using data or playing games obviously. actually this ROM is superb for me performance wise, its just, i feel like i can squeeze a bit more of it for playing games you know. its like i see this slight lagging and i thought if only i could use a little more CPU power, the lag will be gone
Even you can overclock a 1st gen AMD Duron to 2Ghz with liquid nitrogen, it just doesn't make sense doing it
AW: [Q] OC problem
i can oc my cpu to 960mhz but i think it makes no sense... you don't feel the extra speed in normal use only in benchmarks... my cpu is set to 480mhz because it's enough for every app i am using (facebook, whatsapp, xda, browser and so on).

Touchscreen priority in ICS

Hello guys!
I have Xperia arc(LT15i) running modded .587, running on Lupus v10 kernel at 364-1612Mhz, ondemand, sio, with the kernel memory enhancements written on unit.d.(+ disabled cpu rendering and several other unit.d scripts).
Recently i downloaded CSR Racing, just to try it. The problem is that the game is RAM and CPU hungry. The gpu handles smoothly the game, but when the cpu is overloaded, the game continues to run, but the touchscreen is irresponsible for a moment(the problem accures at most of the time, but not always). I tried performance governer with several other schedulers but the difference is bearly visible.
My opinion is that the touchscreen suffers of insufficient priority. Is there any way of having this fixed?

It's not a matter of touchscreen priority, the game takes up a lot of memory so although it runs smoothly, the touch input will lag.

Try with flashing Adreno v.3 drivers - they will make the phone more responsive in every way with nearly to zero UI lagginess!

Thanks for the response! I've flashed them more than 4-5 months ago(instantly when they were out)
EDIT: I want to flash 4.2.2 Jelly Bean. I looked some JB roms and they were told to be very performance friendly... the only thing which prevents me flashing are the JB kernels which are with disabled 720p support.

Better with flashing an custom ICS ROM that you can mod so it act and looks like an JB ROM - it will give you 720p support without any quality drawbacks!

This.
Overclocking -> CPU heats up -> Heat affects nearby parts -> In worse case, your phone parts get damaged (meltdown!)
Don't do it.

Usually i do not play games, and when required for a moment, when running on 1.6Ghz max i have instant response. My phone doesn't get warm, except when charging and playing heavy game or browsing the net via 3G(from which i stay away from)
Thanks for the warning, as i know the silicon melts at more than 130-140C, which i think are hardly possible. Since a long time i've developed for myself a way of holding my phone while having usage with intense processing. Add that i observe my battery and the temperature was never beyond 40-43C while charging and heavy usage.
And thanks a lot for the responses connected with my phone I'll take a note

[RESEARCH] Fix cpu cap problem on TouchWiz Rom

Hello guys,
after a lot of test and research with my friend @ktoonsez finally i want ask to all community help us to fix a problem of touchwiz rom.
This thread is also to try to understand who have this problem as me.
First of all the scenario:
- i9505
- KK touchwiz rom (not important the base, i have tried omega, wanamlite,goldeneye, pure stock)
- Stock or custom kernel, is not important since this problem happens also on completely stock rom and kernel
The problem
After heavy playing games for 5/10 minutes the performance became very very low! Game starts to lag a lot and in few minutes became not really playable! The phone is quite hot in the upper part but not really really hot! Exiting game can fix the problem but not always. Only a complete reboot can fix completely the problem!
So i have decide to investigate and i have installed app like KtMonitor (included in kt kernel) or perfmon (http://forum.xda-developers.com/showthread.php?t=1933284) and i have noticed a very strange think!!!
When game start for the first time the cpu speed is max at 1890mhz
After a while the cpu goes to 1458mhz and stays at this freq for a while
After some minutes it scales down to 1242, then to 1134, then to 1026 then to 918 mhz!!!
*When 1134 mhz is reached gpu goes down to 304 mhz and when cpu is at 1026 freq the gpu is at 128/200
In this way the game is not playable anymore!
The only way to see again values upper 1242/1458 is to reboot or wait a long time (and this suggest me a thermal problem)
How reproduce the problem to see if i'm the only one or not!
Install ktmonitor or perfmon (http://forum.xda-developers.com/showthread.php?t=1933284) and lauch it
Install an heavy game such as Asphalt 8 (https://play.google.com/store/apps/details?id=com.gameloft.android.ANMP.GloftA8HM) or Real racing 3 (https://play.google.com/store/apps/details?id=com.ea.games.r3_row) or Front line commando 3 (https://play.google.com/store/apps/details?id=com.glu.flc2) or Ridge Racer Slipstream (https://play.google.com/store/apps/details?id=com.namcobandaigames.ridgeracerss)
Play for some minutes one of these games and during play monitor cpu and gpu (if you are using ktmonitor)
You should notice the cpu scale!
When u report your situation please report also your:
Rom (version also)
Kernel (version also)
Kernel settings (if available)
Bootlaoder version
Particular apps installed
Particular mod flashed
Thanks to all people who want's help me and the community to make these tests and try to find and fix the problem! If we wait for sammy fix...we can die before
Thanks to all!!
Hi
On 4.2.2 MGA roms the Cpu Min 1222 Mhz and Gpu 450mhz,thermal only underclocking Cpu But On 4.4.2 Game lagging and GPU Underclock at 200Mhz xD playing Games 5 Minutes.
App Cpu Overlay Real GPu and Cpu monitor :
https://www.dropbox.com/s/jseymxs5o7g0fg3/CPU_Overlay.1.0.apk
Rom :Wanamlite 2.4 and Stock NBE
Kernel:Adam 2.1
Bootloaderld
Particular apps:Xposed,Wanam Xposed,Xprivacy.
Particular mod:Quicksetting s5 Vrtheme
Thanks for advance.

Help! CPU freq stuck running at minimum 384MHz despite the kernel or Rom installed.

Current settings:
Kernel: 3.4.94-QuantumKernel-6/17
Rom: Carbon-kk-nightly-20140617-0002
Freqs range: 384MHz - 1512MHz
Governor: interactiveX
and before this rom and kernel install I was running Liquid smooth and it's kernel, Deathly. I've done several clean flashes of both Roms and just recently did a dirty flash of the QuantumKernel again.
So it's an odd situation, because everything runs great at first. Navigating through settings and everyday apps seem great, the cpu correctly runs at the rate it should. But as soon as I launch Clash of Clans, the phone just drops to 384MHz and everything from then on just crawls. Sometimes it will run fine for 30 seconds or so but then just goes back to 384 on both cores constantly. I've tried installing and using kernel tweaker and overriding some settings. superuser notifications make it seem like there are actual changes being made but then it eventually ignores all tweaks I've made and goes back to running at 384. Had this problem with Liquid smooth last week and posted, no replies. So I found Carbon and a recommended kernel in the designated thread and eventually fell into the same situation. I know there are certain triggers where the GPU overrides the cpu clock speeds, maybe it's something with that since it seems to be triggered from Clash of Clans which is a huge cpu hog. I don't know. Any ideas or suggestions?
Thanks in advance!

I'm not so sure why that happens but I would suggest you try KT747. I've been using his kernel for quite some time now and have no issue with CoC.

Thanks for responding! Just flashed this kernel and so far so good. Though I'm confident it'll stay that way. This kernel is amazing! So many options to consider tweaking but then not mess with in fear I'll break my phone. lol But seriously thanks, this is working great!

If you wanna make some tweaking, look at the scripts/profiles. There is a nice directory full of premade by users (as well as one from KT himself)!

Oneplus 3 - PubG Lags!

I've a OnePlus 3 Device.. When I Play Pubg in Med Settings.. it Lags like hell and i turned to Low Preset Still The same any solutions???
There was same problem with me too...
1. Make sure upgrade to v0.4.0.
2. If problem still continues use Elementalx kernel and overclock cpus and also turn on GPU boost to high.
Though regardless to say play on Europe server?
I play with framerate set to HIGH and BALANCED and it runs smooth most of the time.....

Will Try :good:
i'm on latest OOS beta with Derp kernel, no lag what so ever on PUBG , just played it for the 1st time last night, on HD and medium fps (and one mission on high), no lags what so evert, but here's heating normal and expected with this type of games, but didn't effect the game play.
it'll hit the battery though , i went from 92% to 20% in 70 mins of continues playing on high settings. also make sure if you're on OOS to add it to game do not disturb mode, it helps.
i do have same problem on open beta, ill try to flash costum kernel...hope they fix this on next update...

Sorry to say but it will lag in anyway
Coz it is powered by Snapdragon 820 which just sucks in gaming , not becoz of GPU (Andreno 530 is good enough) but becoz of low cores count and thermel throttle ?
And PUBG mostly depends on multicore performance of the processor, in which sd820 littrely sucks (820=450 in multicore performance)
Snapdragon 660 is much better choice for gaming it's much stable than 820/821
Someone said to me to use GFX Tool on play store and enable the vulkan and see the changes. He said it was lagging but after enable the vulkan it turns out pretty smooth after but pretty much drains the battery.

I second this, used GFX Tool with the following parameters:
PUBG M Version 0.6
Resolution: 1280x720
Style: Classic
Graphics : Balanced
FPS: 60fps
Vulkan : Enabled
Anti-Aliasing: Disabled
Running On DU v12.3
Kernel DU stock
Active battery drain after 33mins of use 9% and lags at all.

I dont know, it was smooth here currently on Nougat Zenity RR. But I do also face the lag when I'm using Unofficial RR Luis and I even overclocked the cpu, but it was smooth on OOS with stock kernel and MSM Xtended so far before. That recommendation to enable vulkan was from someone I haven't test it yet since I dont face the lag right now. Sorry can't help much, I also did not understand much why.

Not true , as mentioned on another post above, I also use the latest oos beta ROM, with derp kernel 4.4 , nonlags what so ever , not even a little ...
I've been playing pubg for a month now , and with the above setup I had no lags... I even use maple I/O sched , which by nature may cause some lag and despite that it doesn't.
onePlus stock kernel specially on beta may have issues from time to time, and a lot of cutom kernels for cutom ROMs are configured more toward battery life...
For stock rom use either derp or blu_spark, they will work out of the box without issues, Blu have more heating though on my experience.
For custom ROMs you'll need to ask the kernel dev what settings anss scheds to use ...I'd imagine flash kernel will be ok right out of the box but will not be as battery friendly as the others .
No
Well if you are happy with 20-35fps performance, than trust me you don't really need a flagship, you will be satisfied even with Snapdragon 450 which can give similar performance to sd820 in PUBG lol [QUOTEuke7;76899133]Not true , as mentioned on another post above, I also use the latest oos beta ROM, with derp kernel 4.4 , nonlags what so ever , not even a little ...

Guys if you want to game dont do it on a mobile device. Let alone a cheap China device with high failure rates on hardware.
Could anyone suggest a ROM / Kernel that is tried and tested to not lag on OnePlus 3T? I am currently using a different phone just to play the game and I really wish to move back to my phone ... Any method that is tried and tested to function properly with no lags on the current PubG update would be really appreciated

You will be hard pressed to find a combo that works. You will most likely need to build a rom made for it as most roms are not made for gaming which to be honest is a sad state on mobile device.

Try msm extended pie and aosp extended pie both with stock kernel runs pubg smooth with hd - high fps
Well i'm baffled with you guys, i ran it just fine, i even downclocked it to 1 & 1,5 Ghz (lil&big). My configs: Omnirom and the included kernel (holydragon) downclocked, display driver updated to V313 (look for adreno driver in mi mix forum) use rev15 as it is less glitchy and even has tangible score boost almost 6000 gain in antutu GPU section. And that's it, HD and High setting acquired, i even get extreme setting when i first install the driver, but somehow it disappears lol. If you want to run it even better, use old gfxtool to old pubg apk, run and then update the pubg, immediately uninstall the gfxtool to avoid ban by the new pubg detection for gfxtool. Sorry too long.
