I found a thread here xda about how to overclock the cpu Galaxy Tab 4 7.0 (sm-t23nu). In that thread the creator of that custom kernel had a problem increasing the frequency of the cpu when it came to 1.4 Ghz (version 2.2 kernel) because it appear more laggy. He then later made other version of that custom kernel that was down clocked to 1.3 ghz. So I actually tried the older version it was fast but what I noticed was that cpu was going really fast(everything open up quicker apps processes were getting done more quickly) but the gpu it self was bottleneck the cpu. I noticed that because when game with it that and everything was going smooth and fast but the rendering of the image was struggling to catch up. So I install aida64 on my tablet to see how much Mhz the gpu going at 416 Mhz stock speed but what I really found interesting was that it's not even going at it's maximum stock speed which 533 mhz so it can literally overclock to 533 Mhz and still have headroom for a 5-10% overclock which could be about 650 Mhz. So I was wondering if there's any way to overclock the gpu for this particular tablet. Thank you in advance
Hey
I too create custom kernels for this specific tab and let me tell ya it's a big pain...u can overclock the gpu but it requires changing alot. You have to change the plls the gpu runs on and on top of that it breaks the frequencies the cpu runs on and also the gpu info doesn't show up at all so if u plan on building pull the repository for the tab 3 which uses the same chipset. Then go to the files that are related to to the gpu which all I did was delte the gpu folder and replace it with the tab 3's galore file which will allow u to see the gpu info in kernel aduitor etc etc. Also one more thing I have a kernel with it overclock to what I believe is 1.6ghz.. and the gpu is capale at overclock ed frequency of 832 mhz
Good luck!!!

But that's problem I don't know how plls (what are even plls?) of the gpu? Plus I tried searching out on xda and other sites on how to edit kernel on overclocking frequency on both cpu and gpu but there's barely information how to do so and the only thing I know is that every kernel has different ways of changing frequency within different kernels so it's not the same for usually most of the time. XDA only shows how to add scheduler and cpu frequency also it's very general idea but in the gpu side there's no information about it. Can you give me advice what program I should for editing kernels clock frequency of cpu and gpu? Also where can I learn to edit the kernel for the galaxy tab 4 7.0?

my tab 4 7.0 is 1183 mhz, and yours is half of it? whaaat??
??? 1183 MHz ??!! How did you manage that ?? Mine is at max 533 MHz .... , checking the forum like crazy how to increase the GPU MHz range . Like OP mentioned , CPU already @ 1.4 GHz instead of the default 1.2 GHz quad core speed . But seems that the GPU can't catch up : result rendering images on high end games are slow ( hangs , laggy ) .

Yeah because the cpu is doing everything fast while gpu is like snail due to the low frequency and graphical api (OpenGL 2.0) it has which can not be fixed for api but tweaking the gpu to higher frequency could help alot in cpu overclocking. It would be better if it had OpenGL ES 3.0.

I can't really tell if you are joking or not because you're a senior member and should know this but what i'm talking is GPU-Graphic Proccesing Unit and you are talking about is CPU- Central Proccesing Unit. That's stock frequency of the cpu for that tablet mines also used to be 1183 Mhz in cpu frequency and now I overclock 1.344 Ghz. The problem is when I try to go to 1.4 Ghz the cpu is very fast at proccesing information I can literally have 10 or more tabs in google and multi task and it super fast compare to stock speeds but when I see video or game on it lags because there's a bottleneck with the gpu.

Dude, I'm almost finished with it but I need to know where's the file dvfs-pxa988.c on the Galaxy Tab 4 7.0 kernel like when I go to arch/arm/ mach-mmp there's no file called dvfs-pxa988.c. under that directory. Like do you know where could be?

Same devices like HTC HD2 with Snapdragon, when you overclock the CPU, the same happens with GPU...
But in our case ( defy ) is not the same...
By default ( where i know ) PowerVR SGX530 it's runing AT 200Mhz, but can run higher, than 200mhz ( 400mhz i think ).
We can overclock the GPU to get more 3D performance, witouth sacrificate the battery?
Why do you think the GPU can run at twice the default clock speed?
If there is an article you have read that states or suggests this - please provide a link.
by default it's runing at 110Mhz ( i think )
http://en.wikipedia.org/wiki/PowerVR
the default clock is 200Mhz, and i thing can go furher.
I have seen traces of 125mhz looking in the system files, but thats more of a guess

according to ti, it is [email protected] (all 3630 is)
well it's either CORE_CLK/6 (0x1) or "full speed" (0x0) (CONTROL_FEATURE_OMAP_STATUS)

Ok, but is there any way to overclock the GPU? at 250 or 300mhz maybe?
This program on the market says it can overclock GPU:
Overclocking (GPU / CPU) https://market.android.com/details?id=com.cpufree
but doesn't seem worth trying since it has a very very bad rating and comments.
Last app update was 5 months ago.
Can someone find an app worth trying?

Would be cool if the gpu ups with CPU, but like mentioned above...I think the omap3630 is locked at 200mhz
If anyone knows how to do a gpu OC...please share
dunno about you guys, but as far as i know, the gpu is integrated in the cpu chip (its like an extra core so to say), so it should be overclocked with the cpu. and whenever i ocd the cpu, i experienced graphics improvements, so i think, thats the answer, they oc together.

No they do not OC together i am afraid. Most of Android UI is being drawn by CPU and not by GPU as many thinks :/
Well, I've experienced minor changes when OCing my Defy from 1ghz to 1.3ghz, when using Neocore... it went from 39fps to 39.3 fps, but such small changes are expected, even without OC...
Hi, I have a question!
I'm absolutely happy with my HD2 but I'd like something that the performance increases.
Is there a possibility to overclock the GPU? Cpu is yes to either 1.2 GHz or 1.5 GHz but the power play in is not very noticeable so I would appreciate if you could overclock the gpu order to get more performance out there.!
know her as a possibility?
would answer me happy!
there is an app on the market that allows for GPU overclocking , i didnt use it personally just search overclock in the market and look at the different results . I have no problem with the performance of CPU overclocking , i always thought the CPU was the one in charge of graphics rendering .
Isn't it SOC? As you overclock cpu gpu is overclocked also?

If the SGX540 in P1000 can be overclocked to 370MHz, the performance of it can be highly improved like in Overcome Kernel.
(Can be showed in Quadrant Standard Edition. When it is in 370 MHz, the fps in the graphic animation of DNA can be promoted to 60fps. And got no lagging in anything. The speed(smoothness is nearly reached S2 which is official 2.3.6)
But however, it doesn't seem that any ICS supporting kernel can set the clock of GPU.
I am sorry that my English is not good enough to represent my idea, but I hope you can get what I am talking about.
And the most reason I want it to be real is that the potential of P1000 is quite big and in fact it is quite good!
PS Antutu SetCPU app can set GPU clock in Overcome Kernel.
Dang, I never knew that our GPU can be overclocked ^^
since this tab is getting old, maybe its time to overclock the gpu also?
Personally I'm agree with this
Probs a little off topic, (also to bump this up a bit)
But the Gnex which uses the same GPU can be overclocked to 512Mhz (Stock is 300 something I think), improvement seems noticeable in apps and in nenamark, you go from 27-28ish FPS to 31-32.
It would really help the tab, it seems to show age now (which makes me lust over a 7.7......)
What I knew is the potential of SGX540 in GNexus and GT are different.
GT one is 200MHz and GNexus one is 374MHz.
In Overcome Kernel w/ GT, the clock of SGX540 can be set to 370~38X Mhz w/ no crush but when it is 400MHz , the machine is seemed to be lagged.
The benchmark in Overcome 4.1 plus Overcome Kernel 4.0 can be promoted over the GT 7.7 (of course the mark doesn't represent the real using experience but let's just look at the 3D mark)

Haha, yea I know they have different potentials Just that I thought I'd let you guys know how much better overclocking the GPU would be.
I think its worth it, there is little impact on battery life, but the improvements in apps and usage are noticeable.

I think the battery usage for extra cost of GPU is not as high as CPU.
It is being a great difference if we compared the overclocking for either CPU and GPU.
The consumption of GPU is low and it won't make the device hot as CPU overclocking.
And the temperature can keep around 35 to 36 degree Celsius under a room temperature 20 Degree Celsius.
The result screenshot I have posted is undergoing CPU overclocked (1.4GHz) plus GPU overclocked(370MHz) w/ overcome kernel and rom.
Success!!!

Hello, i have been trying to implement LiveOC into humberos's kernel and it is a success
LiveOC
This allows us to modify the bus speed which increase both the cpu and gpu clock at the same time using an app called NStools
i have only been using this for a day now and it seems to be working very well
please report back any bugs thank you,
BTW i will post the settings i have used in NStools and this kernel is for the latest MTD build
Link: http://www.4shared.com/file/216rF_WJ/boot.html?
My settings:
Governor: smartassV2
min CPU freq: 200MHz (240MHz after applying OC Value)
Max CPU freq: 1000MHz (1200MHz after applying OC Value)
OC target low: 200MHz
OC target high: 1000MHz
OC Value: 120%

I'll give that a try when I get home (or maybe a few days later). So which ICS rom did you try this on?
EDIT: In terms of quadrant (which I know can be a bit volatile... but a nice way/quick way to see differences), ICS gets a lower mem score :< 3d is slightly lower, 2d is about double (I suspect thats forcing 2d rendering). This is comparing the gtab score in quadrant, I haven't used GB on my tab for a longgg time...)

Can we actually oc the gpu on the note 3 ? I have latest AEL Kernel v7.12 and I've put the frequency in the /sys/ folder to 550,600,500 and none work , also I tried with Fauxclock but doesn't work . Yes , in CPU-z it says adreno [email protected] but I launch asphalt 8 or other games and put cpu-z on-screen and the gpu never hits more than 478 mhz , I have laziness on 10 and ramp on 1 . Thank you !
EDIT : I don't know how i managed to miss the "Don't post questions here " sticky but I'm sorry!
Yes, it's possible. It's kernel-dependent, but I have mine set to 487.5MHz, and I can verify that it does, in fact ramp up beyond it's stock limit.
That being said, the limit it's set to is a maximum, so 99% of the time it will be operating well below that. I also believe that it depends on how the app is coded.
I've never seen a kernel with limits as high as you're trying to set them (that's not to say they don't exist though). Maybe try scaling it back a bit? Stock is 320Mhz, so pushing it to 600, if it's even capable of such, seems like it would be incredibly unstable and possibly damaging to the GPU...
Hi guys I'm new on xda and I'm really sorry if I post this thread in the wrong place.
I found a method last year with I think we can overclock/underclock our MTK devices.No custom kernel or ROM is required but the problem is that the CPU can't be overclocked.Only the GPU and other components like RAM and internal memory.
All you need to do is to install a MTK Engineering app from Google play store.
After that go to /hardware testing/DE-sense/PLLs - you will get to a menu with some different PLLs
ARM PLL - is CPU ( but can't be overclocked )
MM PLL - is the GPU ( it's safe to OC )
I don't know about other PLLs , I don't think is safe to OC them and you will not get any boost in performance.
There are the default PLLs values for my MT6582 device ( all clock speeds are in khz )
ARM PLL=1092000
MM PLL=500500 max / 266000 min
MSDC PLL=416000
MAIN PLL=1092000
VENC PLL=295750
UNIVI PLL=1248000
The best OC values for GPU are 315 MHz minimum frequency and 518 MHz maximum frequency,the minimum possible underclock frequency is 245 MHz minimum and 450 MHz maximum
From my tests I got a 10-15 fps boost in PSP emulators and 5-10 fps boost in 3D games (real racing 3,asphalt 8,modern combat 4) and benchmarks (antutu 5,gfx bench)
Here are the default clock frequencys for MT6589
ARM PLL=1508000 max / 754000 min
MAIN PLL=884000 max / 500000 min
MM PLL=338000 max / 286000 min
UNIV PLL=624000
MSDC PLL=208000
Here is the YouTube link,check it if you haven't understand this tutorial : https://m.youtube.com/watch?v=wY_i3u_Wu4w
Anyway I need an expert opinion to tell me what the other components are.
Attention !
- overclock can harm your hardware
- please make sure that you can remove your phone's battery because if you put a wrong value your screen can get stuck ! But if you are lucky your device will reboot
- make sure your device is rooted and you know your default clock speeds
- Do not try to OC any other components,only GPU is safe to OC
- I'm not responsible for any damage to your phone
I can't post this thread elsewhere because I'm not allowed even if I have more than 10 posts,admins please if you find this useful move it to a good location
very interesting. i want to try this on my unite3 lollipop with SoC 6582. but before that i want to ascertain default values for MMPL which i could not find when opened in engineeing mode. will you pls reply how to find default values.

Edit: whether values stick even aftet reboot and how to check it has overclocked or else.
Sorry for so late response but I don't have a mediatek phone anymore. Anyway so no you can't see what are the defualt values in mmpl but you have to find out your gpu clock speeds ( the maximum freq like 600 mhz and the minimum one,which the gpu idles at like 120 or 200 mhz). If you say that you have a mt6582 phone your maximum freq should be 500 MHz and you could try a 533 MHz overclock. Only big problem at this gpu trick is that we can't change the voltage also,so an stable oc will be very small. I reccomend to oc that idle freq which I don't know why this mali 400 uses it even in games making them lag. So try to oc that 200 MHz to 300 MHz,but don't go higher because the kernel will think that you want to change the max 500 MHz freq so the performance will get worse. First set something like 303000 and after 515000.These are some ideal valuse which I've tested by myself. Sorry for my bad english and greetings from Romania.
how about mt6750?
