I dont know if really many knows how to overclock your GPU but i tell it here if you didnt know.
Go to here:/sys/devices/system/cpu/cpu0/cpufreq/
Then open gpu_oc in text editor and change number to 0, 1 or 2 and then save.
0= 307 Mhz 1= 384 Mhz 2= 500 Mhz
I recommend not to oc to 500 Mhz because your tab 2 will get really hot in 10 min. in gaming and other use.
All of them are stable at least for ME(maybe because my tab 2 is only 2 months old but still gets hot)
384 Mhz is good because it doesnt fry your tab and you get faster performance.
I dont know if this workson other phones/tablets but try at your own risk.But remember that in some games CPU overclocking may help too and i know it helps alot in shadowgun dz.
You overclock at your own risk.

This only counts for specific kernels, particularly OC kernels, I use mine at 512mhz, CPU at 1350mhz, runs pretty solid, I use CM 10.1.2 with AGNI Pure CM Kernel, prefer either AGNI Purestock for stock based roms and PureCM for CM roms as Boeffla config app is included, in that app you can set the GPU OC and it sticks, in the other kernels, you need to edit and save that text file after every power cycle.
I have actually looked for that type of app so thanks for sharing that app.
TricksterMOD from play store allows you to OC GPU as well.

Which are the best cpu and memory settings for x8?
Wich rom do u use?
If is minicm, you can easily go to, 729 or 748 mhz with no reboots, smooth and stable

Which is the best app?
You must test which frequency is best for you because every processor is different. One can run on 729 MHz without problems but other can't. You can use CPU Master or SetCPU from Market or other apps
but no need to use 3rd party apps if using miniCM, since you can change OC in cyanogenmod settings
and it's just as dbts25 said, every cpu is slightly different, some people can't even overclock cpu to 614 mhz, and some can go over 800...
i prefer using 691 or 710, these two are pretty stable for me, and my limit is 729 - i can't go higher no matter how much i try - the phone reboots immediately
i'd recommend you to check it yourself, and when you find a good, stable frequency, reduce it by 19 mhz - you'll propably have less reboots, if any at all it's more secure to do so in my opinion.
hey folks,
I would like to know what is the maximum stable overclock possibe for zte blade.
Im using cm7 nightlies and the max overclock frequency i can see is 864MHz. But my device will be stable only upto 691MHz or 710MHz.
What is your blade's max stable overclock.?
I heard some other android devices can be overclocked to their maximum value and remain stable at that value. What about ZTE blade. I think blade gets a lot of performance if it reaches stable at 864MHz. I don't bother the battery life or overheating really.
Is there any hack or something like that.?
672 max stable for me, my old one did 748. depends on your phone.
Has anybody had it over 800 stable?

I think it doesn't really change the speed with that governor, it's designed so you use a program to set the speed yourself, except none exist, I assume it doesn't work at all without it. It needs something to write the desired speed to a system device, if nothing does that then it'll just stay at the same speed.
Test new speeds with performance governor, that keeps the cpu at it's maximum speed, it's not ideal for battery life but you can see if it really is stable at that speed.
I got my blade to 806 mhz, too. I stress tested it with setCPU, and it was stable.
I didn't have the guts to test higher than 806, though.
and I don't leave my phone on overclock.

Just make sure that it isn't set to overclock on boot when you're testing higher speeds. Then the worst that can happen is it crashes & you know it doesn't work. Needs to be done in the name of science, so I know if it's worth enabling 864mhz & above in my kernels, or if nobody can ever get that high.
Nobody has managed to overvolt our cpu (msm7227) yet, I checked Google, it's probably not realistic to hope for it. I'm not sure it's possible at all. So whatever the maximum stable speed for your phone is, you're stuck with it, it'll never get any faster.

It's a totally different cpu to the blade. I could add an option to make your phone run at 1ghz if you want, but it'll just crash straight away, the samsung has a faster & different cpu. We'd need more volts to even attempt it.
Your phone will never run faster than 710mhz stable, if that's what you can get. There is no possible way, other than buying a different phone, to make it run any faster.
I'm still interested to see if anybody can actually run their phone at 864mhz without it crashing, for those few people, they might be able to go faster.
@wbaw , thanks for the info.
Surprised to hear that no one attempted to overvolt msm7227 . I feel it is still a great cpu with adreno 200 included and many current low end phones are having it.
i can get 748 on performance i had it for about half an hour with no reboots
I saw on Antutu benchmark that some people got their blades to 1.5 ghz.
It's probably a hoax.

Hm... The highest CPU rate without crashing was 710 Mhz for my Blade. Any higher values causes a unstable work or just rebooting.
My blade can handle 748 with sd writing but without 806 (but if you write to sd it crashes)

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...)

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

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?
Wont work on my nokia 3 TA-1032
Sorry, this is a late reply but i dont know why it says "Fail to enter De-Sense PLLs module" when i tap PLLs.

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?

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.
