Galaxy S4 9500 onlyStandard Disclaimer: Im not responsible if something wrong happens to your device Read the guide as much as you want before proceeding with overclocking
Overclocking and undervolting is highly debatable, some say its good and some say its bad... so its upto you to decide and proceed further
First rule of overclocking.. Your Mileage May Vary
Most of the people here in xda do know about overclocking and stuffs but still there are many who are so eager to overclock their device . Hence this guide.
I have given some good info below about these stuffs as far as i can , you can always use google to get further details.
What is overclocking?
Overclocking is the process of making a computer or component operate faster than the specified clock frequency by the manufacturer by modifying system parameters. One of the most important techniques is running at a higher clock rate (more clock cycles per second; hence the name "overclocking")
Operating voltages may also be changed (increased), which can increase the speed at which operation remains stable.
Advantage:
You can get more performance from your chipset, though s4 is already fast you can see the visible changes in application execution time and much more like instant response time.
Disadvantage:
* Overclocking is always risky if something is configured improperly and may also result in permanent damage to your hardware. As long as it is done safely you are good to go.
* You may see some increased power consumption.
* Extreme overclocking might kill your hardware.
Undervolting :
The process where you provide less voltage to your cpu rather than the stock voltage.
Advantage:
* Reduced heat from your device.
* Good battery life.
Disadvantage:
* Extreme undervolting will make your device unstable and some times even end up with a boot loop.
Apart from the voltage table defined below for exynos the below mentioned data are common for 9500/9505
Overclocking in Exynos Octa:
Exynos 5410 is already one among the best performing chipset available, so overclocking this device is not going to give us any visible performance improvements except the benchmark scores. Underclocking is a different story on 9500, since the cpu temperature easily reaches upto 90C (90C is the throttle temperature defined for this device in the kernel, so its normal) undervolting the device will help in reducing the overall temperature of the device considerably. I highly recommend undervolting the device instead of overclocking it.
Exynos 5410 has 2 cpu clusters, stock voltages and available steppings are given below
Little Cores (A7) stock voltages
Code:
[B]STWEAKS[/B]
1200mhz : 1225mv
1100mhz : 1125mv
1000mhz : 1100mv
900mhz : 1037mv
800mhz : 987mv
700mhz : 950mv
600mhz : 950mv
500mhz : 950mv
400mhz : 950mv
300mhz : 950mv
200mhz : 950mv
Samsung divides the actual clock of a7 by 2 while displaying the steppings in order to accommodate the big little way of displaying values. Stweaks will show you every available steppings like above whereas most other cpu tuning apps show it like below, both are same though. stweaks @ 800mhz is equal to other tuning apps @ 400mhz
Code:
[B]OTHER CPU TUNING APPS[/B]
700mhz : 1225mv
550mhz : 1162mv
500mhz : 1100mv
450mhz : 1037mv
400mhz : 987mv
350mhz : 950mv
300mhz : 950mv
250mhz : 950mv
200mhz : 950mv
150mhz : 950mv
100mhz : 950mv
Big Cores (A15) stock voltages
Code:
2000mhz : 1250mv
1900mhz : 1250mv
1800mhz : 1250mv
1700mhz : 1200mv
1600mhz : 1162mv
1500mhz : 1137mv
1400mhz : 1100mv
1300mhz : 1062mv
1200mhz : 1025mv
1100mhz : 1000mv
1000mhz : 962mv
900mhz : 925mv
800mhz : 900mv
Though the cpu frequency table has steppings upto 2ghz the max stable clock i have seen so for on s4 is 1800mhz.
Requirements:
1. Kernel with overclocking/undervolting support.
2. stweaks or android tuner to change frequency/voltage.(you can use the app of your choice here).
3. set cpu and stability test to test the stability of CPU.
4. Some patience.
The below mentioned steps are common for 9500/9505
Step 1:
Set the current clock and voltage you want to test via android tuner/stweaks. (Select max frequency in cpu tab).
Example:
*If you want to test under volting for 1.4 ghz with 1050 mv (1100 is the default) then set 1.4 ghz as max clock and 1050mv as its voltage.
*If you want to test overclocking @ 1.7 ghz with 1150 mv (1200 is the default) then set 1.7 ghz as max clock and 1150 mv as its voltage.
Step 2:
Open set cpu's cpu stress test and run it for atleast 10 minutes. If you didnt get any errors or hang during the testing period and if the test completed successfully then the clock is ready for daily use
Step 3:
Now for undervolting use the same tools and reduce the voltage by -25mv.
Repeat step 2.
you can reduce the voltage further by -25 mv after every successful completion of stress test (Advanced users can try reducing -50mv )
Step 4:
Repeat step 1,2 and 3 for every possible cpu clock you see in android tuner/stweaks.
Note the stable cpu voltage for every clock, once you finish testing all your clock values save it as a profile and/or set it on boot.
Voila !!! now you have finished overclocking/ under voting your device.
Notes:
1. Never ever use set on boot option until you find the stable clock and voltage settings.
2. Not all chips are capable of running at higher speeds like 1800 mhz. Those speeds are highly experimental.
3. Recommended max overclocking is 1700 mhz.
4. If your device gets hotter allow the device to cool for few minutes before starting the test.
5. Either use stweaks or android tuner(or some other app), dont mix up.
6. Combining the overclocking and undervolting will give you the best of both the worlds
In case of emergency:
1. If your device becomes unstable and not responsive either press the power button until your device restarts or pull out your battery.
2. Android tuner has an option to create flashable zip for resetting the voltage table, use it if needed.

well written and elaborate..thanks
thanks for the valuable input, but i differ on one thing. am using a 2Ghz overclock and is rock stable. using the GPU in the highest clock too....am attaching the STweaks values, battery and antutu score for the same. the device runs very cool too...hope this helps somone.
I do not know if am I doing it right or doing it wrong, but my phone runs without the (very occasional) hiccups and is as cool as it can be....and dat wat metters to me

hmm, with 400Mhz more You have same results as stock? something is wrong, maybe settings do not apply or overheating is causing cpu throttling down so scores are so low.

Every chips has different mileage, even if his chip runs at 2ghz, it will throttle down in very few seconds.

I increased the voltages as advised by u but the quadrant results are around 13000 benchmark...
I'm currently using Omega 8/Perseus 3.4 along with the cross breeder....
My phones very snappy but just wondering about the quadrant result... Is there anything I'm missing???
Plz advise...

looks like your chip is cooked well
Hello, I just rooted my S6 and installed the xtrestolite rom which comes with the unikernel. I installed the SetCPU app, but I have two problems:
1. The default speed was set at 1296. Does this mean that if I wouldn't have modified the speed, I wouldn't have profited of the CPU's whole power?
2. It only goes up to 1.5ghz, though it says that it has 4 2.1 ghz and 4 1.5ghz, but I don't see how I can clock the other 4 cores with SetCPU. How do I know that 2.1ghz is really being used?
Thank you!
+
Betterbatterystats doesnt show up any 2.1 ghz info
...
Meanwhile I found this program CPU Z that shows all of the 8 cores, but that still doesn't answer my first question. If I hadn't modified the CPU speed, it means I wouldn't have had the 1.5 ghz speed??
Hi there,
You'd be best served asking for help from the experts who own your device here:

Please stop spamming the forum with your fake kernel
At least tell me which os version for this kernel ?!
Holy molly ...

What a surprise
3.5ghz? childplay, my cpu works at 40ghz and gpu at 35ghz !!!
Seriously guyz , this thread is fake and it should be reported
This looks crazy. But goodluck bro I hope this will be a success like Wolf and Extreme, fake or not.
This kernel have same based like wolf kernel, are you already ask him for permission?
Anyway, for compatibility. This kernel should same like wolf kernel, because using same sources without any modification from OP that i can found it (Dunno if OP still not push it to github or not).
Anyway, good luck

Can anyone over clock Exynos 7870 GPU to 1.5Ghz or +,i'm not developer only some of little bit game lover & web developer ,I use many kernel and Roms that support
1.7 Ghz CPU and 1.1Ghz GPU but when ever I play any game even on high frequency game lagging ,even on 1.4Ghz CPU frequency result is same ,mean over clock GPU help better performance on system and Gaming.
Hope any person understand me. Please do something that help Exynos 7870 users.

Hardware limitations exist mind you... Devs just can't keep pushing OC beyond a certain point. That point for the GPU of the phone exists at around 1000-1146 MHz while for CPU the highest fully stable OC is at around 1690 MHz while some kernels try to push to around 1920 MHz but some devices at this stage crash or are very unstable so no one can push any higher unless you want your hardware to be toast that is by supplying enough voltage to sustain those clocks...
