[Q] under clocking?

Hi! my s4 is i9500 octa version
hmm well i want to underclock it to redect heat and battery and btw many things
i want to know is it possible to underclaock the GPU not cpu
i currently underclaocked cpu using system tuner and turned it to 1ghz btw im not sure if its on the powerful ones or the other ones! btw after underclaocking to 1ghz it still runs freaking fast! also freaking cold! i wanted to know if i can undercloack GPU too and maybe know wich cpu im on!

Its just fine as long as ur device is working smooth and fast do not go for Scores as it depends all the times with various factors

u right btw the only thing lags is camera and gallery they HORRIBLY lag only at start like it takes 10 seconds to load gallery and 10sec to load camera! btw also 1 time it restart after starting camera other things are fine! btw guess not smooth as nexus 4 i had before changed it coz of vendor mistake btw i love this phone

Try to update the phone to current firmware for camera and gallery issue there myte also be a little delayed incase u have a sd card and its less in terms of class like 2/4 etc

oh u right i got a class 4 stupid sd card i fidned it somewhere in home seems it was forom a old camera btw my father ells me i will get u and 32-64gb when u got out of space but he doesn't know thats 4

i think it wasent like that befor sd card THINK i can't remmbe well but i temmber some day i turend camera it freezed for about 20 sec and restarted
and oh my s4 the alaxy s4 i9500 logo the black ad white just appears not like others sawed in youtube.. (it appears whit a effect from top - to bottom

[Q] Hey guys, newbie here, got a question

I am sorry if what im about to ask is already posted somewhere (probably is), but this forum is pretty vast and I couldnt find what im looking for. The question is this, Im using Vanir ROM. Now with the inbuilt kernel I had around 20k benchmark on antutu. I flash hells core, excited to see any difference and whoop, i got 14k. Also i checked the part with 3D testing and fps was higher for about 5-7 points. So what Im asking is this,What is the meaning of this and also how can I, how to put it to not sound noobish, tweak the kernel to perform/save battery etc.?Because Im assuming thats not the top what HellsCore kernel can do, am I right? Or if you guys have any kernels to recommend, all is appreciated. Also if this helps, Im using Nexus 4, Vanir ROM(as posted above) and dont know what else would you need to know to answer.
Thanks in advance
/So I rebooted and now I am on 20840 for some reason.

Benchmarks are not very conclusive abnout anything. Each phone is different each user has different needs and how and where there phone is used. Everyone will tell u to try this kernel and that kernel but u just have to find one that works for you

I get that, i was more concerned about those numbers. Why did it drop to 14k and then went to 20k again.

Probably some patches were included in the rom's kernel, which can affect the scores.
When you flashed another kernel (helldoctor), you stopped using these patches, so scores went down.

Anututu and other benchmarks depend on a number of factors/conditions which affect the final result . The major conditions which affect it result are below
1) The CPU temperature !! When ur phone gets hot the CPU throttle will automatically reduce the active cores and the clock speed to cool down your CPU !! This results in decrease in performance !! When you flash new kernels its possible that ur phone is hot and hence performance decreases
2) Using your phone while running tests also affect the results . for eg if there is a notification during the test or background sync going on it will affect the result
3) probably the kernel packed with vanir had 4 cores active all the time to increase scores and hells core has just 2 cores active ( at a given moment) will mean decreased performance
The ideal way to test kernels is as follows
1) Dirty flash your ROM before flashing kernel
2) Reboot your device after the first boot
3) Let it settle down for an hour
4) turn of data/WiFi during the test
5) see the kernels specs( like cores active/the maximum CPU speed) through an app like trickster/faux clock
6) Now run the test
7) after test let your phone cool down for 15 mins
8) repeat the test a few times and take the average of all scores
Kindly hit the thanks button as a token of appreciation

Antutu was never accurate if you ask me. Sometimes it goes down and the other it went up..so..

I see, thank you guys.

Benchmarks are like putting makeup on.

[Q] facing gaming problem after kitkat update

Hey guy's, I am facing gaming problem after 4.4.2 kitkat update.my frame rate decreases , gaming become very laggy, can I root my device then using custom rom can I get back my same gaming performance. Please help me thanks

I have the same problem

Dude, use the latest NH6 version + the Force GPU Rendering trick (from Developer Options).
To some limit, this helps (but unsure if the framerate goes back to normal, because I never played heavy games while I had Jelly Bean).
Check and, please, report back.

Hey.. Go ahead to my thread.. And my work is successly make lag gone! .. But. Remember to install busybox first.. My thread : http://forum.xda-developers.com/showthread.php?t=2867166
If you like my post.. Dont say thanks... Click the Thanks Button

Almost all games lags ... I tried ticking force gpu rendering ..btw still games lages ..any way to fix ?

@white7561
His work greatly cuts lags, combined with Scary Performances (not sure of the name) which was shared by @sanjujoseph
Not totally cutting, but a great deal faster.

please help , bentchmark score is always low ...

Hi everybody
my note 4-exynos has been unpdated to lillipop ,
I tried some bentchmark apps and all the scores are lower than my previous phone ( note 3 - snapdragon )
also tried a custom kernel ( ultimate kernel ver.20 ) and the antutu score is still about 32000-33000 !!!
i tried to change the governor and change but still the same ...
tried to factory reset and flash the lillipop again , but the score is still to looooow :crying:
what should i do ? what is the problem !!

please help me (

Benchmark scores are first of all meaningless, don't get upset if the score is low. Those scores mean ****e.
Still, as you are concerned, well, those scores are related with hardware as you can guess, and that hardware need to be cool to give you better scores. So don't keep running Antutu, leave the phone for half an hour or so (when nothing is running on background) and then run it. A hot device can never achieve high scores, never.

Are you ****ing serious or what...??? Benchmarks DON"T MEAN ANYTHING! If your phone is a fake then you can check it by downloading some apps like CPU-Z and Phone INFO from the play store...post pics here so that we can see.

lolipop has a GPU bug... I have the same issue... scoring around 43k. First time when I installed lolipop I got 52k then got the bug (don't know how). I reflashed 4.4 then lolipop thousand times with same results.

The captcha isn't the whole sentence, I believe they ask for the numbers which are shown in the captcha.
And benchmarks don't say anything imo, its just a number. Better just test a game like Real Racing 3, if it runs smooth you won't have any problems.

You reflashed you firmware so many times just to get higher numbers in some benchmark app...?Seriously, I think you got a problem.

Man i have the same problem here it after the update seems that the phone is always in power saving mode and the gpu is limited to 350 mhz instead of 700 mhz. Also the cpu runs at 1.3 ghz instead of 1.9 for the big cores thats why it has low score in antutu hope somebody figures out a solution and also this is a bug in this update
Sent from my SM-N910H using XDA Free mobile app

Yeah, the gpu throttles quickly, that's what I have noticed. I have let my phone cool down and I got 54600 in AnTuTu. The problem is there when the chipset is working at high load. KitKat had throttling limit pushed further so there were no issues with performance. Lollipop seems to have introduced more limits to the gpu because the cpu actually seems to be performing better than before.

Problem with heat up my sm_n900(only with game need graphics hight)

Hi evey one.. (the first thing i'm sorry for bad language)
I have proplem with my device n900 when i play game need graphics (like modern compat 5) the device heat up and start lagges some time put my device font fan becouse the device like ? ... I tried more roms and no solve i flash LineageOS 14.1 and open to app to control cpu and gpu frequency and no solved and try to less than graphic of the same game and no solved but take some preform better.. Any solved please i ask if i flash good kernal the proplem solved or not?
Please help me if u have solve.. And thanks for all

What does your rom developer say ??
Sent from my SM-N930F using XDA-Developers Legacy app

@JJEgan No answer.... The orginal developr do not answer
But another user respon to me this proplem not maked to me
This proplem with stock rom and cook roms.
My question proplem heat up my device is normal or not

Resource-intensive games push the CPU and GPU to their highest frequencies. The heating is quite inevitable in this case whatever the ROM or the kernel used.
However, to reduce the heating you can under-clock your CPU but expect a performance drop in-game.

I know games is push the CPU and GPU
But asking for the best kernal and rom
If take me 50% better this is i want it
I ask for anyone know the best?

My question proplem heat up my device is normal or not
You have been answered in post four .

The overheating is absolutely normal when running modern games on a +3 years old device, especially when this device uses the "famous" Exynos 5420 SoC.

You are free to try other kernels or roms .
There is no best rom or kernel .
You would be better sticking to a stock rom in my opinion .

Thanks for answer and help

The stock rom is the same problem with heat up my phone.. I tried more than 5 roms and all the same problem with heat up my device
