If you are a beginner......DO NOT TRY THIS (Fast-guide)
These are my new "safe" OC/UV/OV settings:
EDIT 7 dec. 2011:
Indeed for those sgs devices that are tough to overclock . a kernel with 6 frequencies is needed
Just noticed another great development:
[KERNEL] MIDNIGHT-/BLN/Voodoo10/UVOC/extendedCWM/...
http://forum.xda-developers.com/showthread.php?t=1199140
Great optimized kernel with many features and 6 frequencies !
Right now for JVT and higher , is the only kernel that I can OC/UV and stable as long as I use these settings:

OC/UV App: Tegrak Overclock Ultimate
Governor: Conservative (but "Ondemand" is doing fine too)
Scheduler: CFQ
Code:
Frequency Core Voltage Internal Voltage
L0 1180 MHz 1310 mV 1110 mV
L1 1000 MHz 1275 mV 1105 mV
L2 800 MHz 1150 mV 1100 mV
L3 400 MHz 1050 mV 1100 mV
L4 200 MHz 850 mV 1000 mV
L5 100 MHz 825 mV 950 mV
Remarks / Tips :
- I use Tegrak Overclock Ultimate app and nothing else, in order to avoid conflicts
- I enphasize, use only one OC/UV app , meaning, uninstall the rest
- In Tegrak I never use the "CPU max frequency" feature , I just load the overclock module and go straight to the " optimization " feature.
Here is a Tegrak guide just in case: https://docs.google.com/document/pub...O4RLIXihSo3yBA
- If your device can handle it and depending on your use, you could try more undervolting and/or no overvolting at all and even more overclocking....BUT...if it will be "healthy" for your device, specially on a long-term, that's another story .....
Because my sgs never handled OV/UV that well ( but it performs great in all other fields), I think these settings are stable for anyone.
But please, report eventual crashes (with these settings, if you do try it)
Ps- I tried it on both file systems (Ext4 and RFS)...in my case, it is more stable when on RFS...
« »
Thanks - will try these setting out later.
Am new to OC/UV, still getting my head around customising my ROM's
That's the spirit, no hurry
Just forgot to mention that the Rom I am using is CriskeloGinger v79*
Adding to first post and also adding a remark about ZRAM (A feature present on TalonDev kernels and its variants)
*Edit: Not using a Cooked rom at this moment, just the stock JVR deodexed/zipaligned and with some mods
New settings update on first post
Adjusted after testing stability using RockPlayer....
Also new versions of Talon SH and TalonDEv kernels are launched
testing these settings now
i'll report back later
ill test it too
OK...only that I stopped testing OC/UV on kernels with 5 frequencies....
So for those sgs devices that are harder to OC, users will need 6 frequencies...
I am very content with the latest Talon SH BIGMEM kernel....highly recommended
BetoNL, nice "fast" guide you have here
Will try soon when I get my phone back to stock
Thanks!
Looks like these settings are quite stable indeed. Not having any problems so far...

Just cf-root on 2.3.5 jvs. I can only set 5 profiles instead of 6 but it works fine. Using tegrak overclock ultimate

my SGS have never been in good terms with OC i`ve tried it a couple of time and my phone just freeze.. didnt record the setting though.. but this is good.. maybe i could try the set again.. but right now i`m using the MIUI 1.9.23.. maybe its time to flash the glitch or platypus ..

Ok...I am updating first post and adding stable settings for Kernels with 5 frequencies like these:
Code:
[B]
Frequency Core Voltage Internal Voltage
L1 1144 MHz 1285 mV 1105 mV
L2 800 MHz 1150 mV 1100 mV
L3 400 MHz 1050 mV 1100 mV
L4 200 MHz 850 mV 1000 mV
L5 100 MHz 825 mV 950 mV
[/B]
If somebody try this, please report how it goes, cause I no longer use 5 frequencies
hi betonl,
what r ur settings for scaling? 100-1000, 100-1180 or anything else?
thx in advance.

Hi there,
My settings are exactly as in first post.
The kernel I use got 6 frequencies (on my sign.)
Grtz
thanks
Testing these settings now thanks
Works fine thanks for settings

SEMAPHORE KERNEL !!!!
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?
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.
There is no de sense pill option in mtkengineering mode on my device mt6761 android 8.1
Hi, on the internet i saw that Snapdragon 615's max freq is 1.7 ghz. Can we somehow make a kernel that allows OC to 1.7
CLICK HERE TO VIEW PAGE
We can. Do you want to be the one who wrangles the code?
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?

there is no file by that name... our tab uses this file for its voltages...android_kernel_samsung_degaswifi/drivers/clk/mmp/dvfs-pxa1L88.c
What are the real frequency of Snapdragon 660 that use in this device...
If any one share screenshot that would be awesome....

Need to be 2.2ghz
This SoC support up to 2.2 GHz.
But On stock kernel set to 1.96 GHz.
Waitting for custom kernel..

They said it in the wrong way, I also saw some videos saying "1.96 GHz variant of sd660". Nope. It's just underclocked. That's all.

You need an overclocked custom kernel for that. Kernel auditor just tunes the parameters.

Battery optimization of course. Youll find shortly after that the battery will drain faster if youve reverted back the kernel to 2.2ghz. they are eliminating the use of high frequency performances under low load conditions.

I guess that might be it... But with root (kernel adiutor) we'll probably be able to adjust the higher frequencies ... In case someone comes up with a custom kernel... Since the sources are already released..
