Overclocking and undervolting questions

I have searched everywhere for info on suggested speeds. Can't find anything. I am running racks dual boot SD card. The default speeds are as follows:
1: 300 mHz, 1v
2: 600 mHz, 1.1625v
3: 800 mHz, 1.3v
4: 1100 mHz, 1.35v
5: 1200 mHz, 1.375v
I have it overclocked and overvolted with nook tweaks. I guesstimated on the voltage:
1: 300 mHz, 1v
2: 600 mHz, 1.175v
3: 900 mHz, 1.325v
4: 1200 mHz, 1.375v
5: 1400 mHz, 1.4v
Are these good settings. By the way I an using interactivex governor. what are you undervolting at? Thanks in advance.

Have you looked through this thread, CM9 is using the same kernel as CM7 so I would expect what is said in this thread would apply to CM9.

I have looked at that thread and that is the app I am using. What I want is the stable overclock frequencies and their corresponding stable undervolt settings

The problem is... all our devices are not quite perfect at overclocking... most will overclock up to 1100... I think your 1400 will cause you a lot of stability issues.

But don't users there say what settings have been working for them? If not, look in the CM7 general discussion thread. I remember a lot of discussion there or one of the other CM7 threads.

This is what I found too. That the nook can only overclock to 1100 and be stable. I originally bought a card from nook to Android company (don't do it) then got a reader and installed racks dual boot card. N2a company said that the nook can overclock to 1200 and was set to that. The racks card was also set to this on both roms. People have been saying that ics is still in beta, but I have found ics to be amassing. It feels like a final release more than beta. Never one force close and the only lag is in nook color tweaks when changing CPU frequency. Ics is my default boot (also nook tweaks app) and I have found it way more responsive with my overclock and volt settings. I am thinking about rooting and putting ics on emmc.

@J.P.
fugumod is not stable for all people and also has sound clicking issues.
Please then make 2 versions roms, one with fugumod ultra (OC-rom) and one super stable with fugumod 2.4beta3 (800mhz if you want).
Also the old kernel g3mod 1.3 ultimate is very fast (@1200Mhz max, also bus OC, incl. sound clicking)..but stable...maybe a good alternative for fugumod ultra?
Regarding the sound clicking (both FM-ultra and g3mod1.3U ..a remedy for it is to set the cpu sampling rate to 0.2 sec in init.d startup script.
echo "200000" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate

This config will be the best for gaming:
Install any kernel that can support up to 1000+ mhz
Install CF3D + Qualcomm plugins
Use setcpu to config the cpu clock to 1000+ mhz
Run the game and the phone will fly

T-Mobile kernel. ***********DO NOT FLASH ON YOUR ATT, SPRINT OR VERIZON PHONE***********
Romanbb said:
Heyo
I've compiled a *very* simple kernel for our phones just to play with
001
- O/C to 1.8ghz by default
- insecure
002
- should boot up to 1.5 by default (read more on this below the log)
- raised max clock to 1.89GHz
- lowered voltage on a many frequencies
- added init.d support (busybox needs to be installed to /system/xbin!)
Also I'd suggest having your OC app (like SetCPU) go ahead and set your clock at whatever you want your max to be. thermald (a service which watches your phones temp and lowers it if it gets too hot) seems to be messing with the clocks until you set one after it's all booted. So if you don't want to OC, just set it to 1512000 in the app and click "Set on boot" option or whatever it may be.
================================================================
More to come as I play with it. Seems pretty stable (and warm!) at 1.8 ghz.
Thanks to faux123 & mdeejay for helping me out with a few things
Flash at your own risk. Make sure you have a NANDROID backup. Flashing the stock kernel via ODIN may not be enough to restore your device. You've been warned

I don't really care for OC, since 1.5GHZ is SO MUCH POWER.
But I would love to be able to undervolt it to save some battery power throughout the day.

[GUIDE] Galaxy S3 CPU/GPU overclocking/undervolting (Updated 12/08/2012)

Only for international s3 variant ​Disclaimer: Im not responsible if something funny 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 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 beast . 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 s3 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 of 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.
Dividing the guide into 2 parts CPU and GPU
CPU
The max clock that can be used on our s3 is 1800mhz and the minimum is 100 mhz. Below given is the stock voltage for all clocks for your reference.
1800mhz : 1450mv
1700mhz : 1400mv
1600mhz : 1350mv
1500mhz : 1325mv
1400mhz : 1275mv
1300mhz : 1238mv
1200mhz : 1175mv
1100mhz : 1125mv
1000mhz : 1088mv
900mhz : 1050mv
800mhz : 1000mv
700mhz : 975mv
600mhz : 963mv
500mhz : 938mv
400mhz : 925mv
300mhz : 900mv
200mhz : 900mv
100mhz : 900mv
Requirements:
1. Kernel with overclocking support.
2. ns tools 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.
Step 1:
Set the current clock you want to test via ns tools. (Select max frequency in cpu tab).
Step 2:
Open set cpu's cpu stress test and run it for atleast 10 minutes. If you didnt get any errors on those 10 minutes and the test completed successfully then the clock is ready for daily use
Step 3:
Now for undervolting use the same ns tools and reduce the voltage by -25mv.
Repeat step 2.
you can reduce the voltage further by -25 mv after the completion of stress test until the app become unstable. (Advanced users can try reducing -50mv )
Step 4:
Repeat step 1,2 and 3 for every possible cpu clock you see in ns tools.
Note the stable cpu voltage for every clock, once you finish testing all your clock values save it as a profile in nstools and set it on boot.
Voila !!! now you have finished overclocking/ under voting your beast The very same guide can be used to underclock you cpu.
Notes:
1. Not all chips are capable of running at higher speeds like 1800 mhz. Those speeds are highly experimental.
2. Recomended max overclocking is 1600 mhz.
3. If your device gets hotter allow the device to cool for few minutes before starting the test.
4. 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. If you end up with the boot loop due to extreme undervoltage below is the cwm flashable to reset your voltage.

GPU OVERCLOCKING
DIsclaimer :
*** I dunno if any other kernels support the very same overclocking , if it is possible kindly inform me ill update it in the post.
*** Using custom kernel or siyah kernel is purely of your choice, im not held responsible if something goes wrong​
I would say GPU is by far the weakest hardware in s3, its weak in the sense that its using the very same architecture used for galaxy s2 with some additional improvements to clock it higher. Thanks to the head room given, though the maximum clock for our GPU is 440 Mhz we can over clock it to around 700 Mhz which is roughly 70% more than the stock. Yes it is possible. Thanks to our developer "gokhanmoral" who made it possible.
Advantage:
* Games can be made to run more smoother.
* Much smoother UI.
By default stock mali 400 GPU has 4 steppings , its clock frequencies are as follows
160 Mhz - 875 mv
266 Mhz - 900 mv
350 Mhz - 950 mv
440 Mhz - 1025 mv
Once you install siyah you will be having an additional GPU stepping(totally 5) along with the following available frequencies to choose from.
54 Mhz
108 Mhz
160 Mhz
266 Mhz
275 Mhz
300 Mhz
333 Mhz
350 Mhz
440 Mhz
533 Mhz - 1025 mv
600 Mhz - 1050 mv
640 Mhz - 1050 mv
666 Mhz - 1075 mv
700 Mhz - 1100 mv
800 Mhz - xxxx mv
The voltages for the above additional clocks are purely approximated values. So you can either undervolt or overvolt it as per your need.
Sample screenshot of stweaks gpu interface
REQUIREMENTS:
1. Siyah Kernel 1.5 beta 6 or higher
2. Stweaks
3. GLbenchmark 2.5(Egypt Classic and Egypt HD)
4. Basemark ES 2.0 Taiji
5. Nenamark
Testing methods and procedure:
Step 1:
Install siyah kernel and other mentioned apps and get used to stweaks.
Step 2:
Select the gpu frequency in stweaks along with the recommended voltage and apply the settings.
Step 3:
Open the above mentioned benchmark suits and run it.. if you feel any stuttering or artifacts when running the benchmark then you need some more voltage. Exit the suite and increase the voltage in stweaks by + 25 and restart the benchmark.
(** Egypt HD benchmark does stutters with currently all the mobile available in this world as the test is designed to stress the GPU to its maximum.)
Step 4:
Repeat step 2 and 3 if you need underclock/undervolt your GPU.
Notes :
* Though there are many available frequencies to choose from i would recommend not to use 54 and 800 mhz.
* Make your GPU steppings gradual (Eg : 1xx-2xx-3xx-4xx-5xx)
* If you feel your device warm let the device cool before testing.
* You can monitor your gpu frequencies in real time by using a tool called mali gpu status(caution: do not use these apps when benchmarking as it will degrade your result)
* Dont use any onscreen overlay apps like cool tool as it will degrade your benchmark scores.
Some benchmark results :
Below is the result comparison of basemark 2.0 (mobile with hd screens). Stock s3 gpu scores around 38 fps.
Here is the result achieved with max gpu clock of 700 mhz. It simply smashes all the records.

Nice work mate :thumbup::thumbup:

Interesting
Thanks, Bala - though I have tried doing this for my S before, I havent seen the need yet to do this for S3.
Having said that, if you have the right OC, UV combinatons that worked for you - do you mind sharing them. That will be the best use of this thread.

300mhz and 400mhz are not utilized by many kernels so its more or less useless. either 200 or 100 can be used for minimum

It depends on the app its not an strange act, if the app requires a lot of cpu usage it will stay longer on the max frequency, if you dont like that you can always try an lazy cpu scaling governor (controls the behaviour of the cpu)

What does this do?
Kernel developers make their kernels to be "universal". By universal, they want the kernel to work on as many phones as possible so they may only mildly undervolt. However, some phones can handle a more aggressive undervolt. Some can't. viperMOD allows you to undervolt to your choosing for better battery life or allow you to overvolt to make your phone more stable.
Click to expand...
Click to collapse
Standard Features
Read voltage table
Lower frequencies by 25mv, 50mv, 75mv, or 100mv (incremental each time)
Raise frequencies by 25mv, 50mv, or 75mv (incremental each time)
Custom voltages for any frequency (with error checking - can't set voltages higher/lower than the next/prev frequency)
Reset voltages to kernel default
Read your init.d voltage file
Backup/Restore your settings
Cool Things to Know
Nice array list for frequencies (universal compatibility)
Lots of error checking (very hard to screw this up )
Should detect voltage tables that are in either millivolts (850) or microvolts (850000) when using the raise/lower features
Click to expand...
Click to collapse
Compatibility
viperMOD will work with any kernel (Sense/AOSP/etc) that supports the vdd_table in either of these paths:
Code:
/sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
This is standard in most HTC kernels. If you have a Samsung or other device, it likely will not have this path. However, I do plan to add support for as many devices as I can. More info on that in the second post

How do I run this?
Once you flash the .zip go into your Terminal app (I use Android Terminal Emulator set to 10pt font) and type:
su
vipermod
(if you forget to type su, the script will attempt to run it as root anyway for you!) I really only use Terminal for this and there is something really cool you can do with Android Terminal Emulator (and maybe others). Menu > Preferences > Initial Command > type su > Press Enter again and type vipermod
Every time you start Terminal now, it will open right into viperMOD. You can quickly exit by pressing Enter if you need to use Terminal for something else

How to get this working on an unsupported kernel​
If you have a kernel that isn't supported, you will see a message about it when you try to run viperMOD. This means that your kernel doesn't use a standard voltage table and viperMOD cannot adjust voltages. I do want to make this work on as many devices as possible, though. So if it is not working for you and you would like me to get it working, please tell me the following info:
What device are you on?
What ROM are you on?
What kernel are you on? (Provide me a link to it, please)
If you want to be proactive about it, you can search the thread or ask the kernel dev about if their kernel has an sysfs for voltages. If so, I need the location of that table and any relevant info about it (if they interact with voltages different than normal, etc). I will try to track this down if you do not provide it, but it does make the process easier for me if you have this info already

It look like its drawing too much power!
BTW I read one of your posts talking about cpu governers explanation - i forgot the link, can you share with me please!

What is the advantaga of using this script over some unvervolting program which I am using at the moment to undervolt?

Truthfully, probably nothing. Not sure if your program does custom undervolting per frequency or not. It's just a cool little script, I think

Does it support automatic process of finding lowest voltages?

No, and I'm honestly not sure how any program could do that without crashing your phone :silly:

There are scripts on desktop linux systems that do it.
I was asking because you mention
"Custom voltages for any frequency (with error checking - can't set voltages higher/lower than the next/prev frequency)"
and it could have meant that.

If you have a link to something like that, I would love to see it! And I meant that as if you have 200mhz @ 800mv, 500mhz @ 850mv, and 800mhz @ 900mv, you can't set 500mhz to 750mv or 950mv, for example. Cause that can cause issues with frequency table.

Those scripts involve running mprime to check for processing errors.
By the way, with my Desire I found a strange behaviour. I can set 998Mhz and 788Mhz to 0.8mV, but if I try to do the same with 128, 245, or 384Mhz, system crashes. But again 19Mhz (deep sleep) works fine on 0.8mV. Normally, if a higher frequency works on low voltage, then lower freq must work on at least the same voltage. But not in this case, which is very weird.
