I am trying to overclock gpu of my rooted s22 ultra using fkm/smartpack but I am unable to. I set gpu to higher minimum freq but it keeps resetting as soon as I exit the apps
{Mod edit: Quoted post has been deleted}
no i haven't been able to overclock gpu yet. i guess the default kernel is stopping this. currently i dont know of custom kernels for s22u so i was wondering if someone has been able to overclock in some way

hi every1.
I've been searching but didn't find any info about the topic.
Does someone knows how or just tryed already to overclock the gpu to higher rates? (i would like to get more to play better games).
another question: i'm using the matr1x kernel (17.5) and in the menu i have an option to overclock the gpu but there're options to get it to 1000Mhz? really?
Which are the riscs?
I apreciated any info.
thanks in advance

stock nexus s gpu is at clocked at 200mhz. you CAN NOT overclock it 500% to 1000ghz. thats just silly. thats like overclocking your cpu to 5ghz. the highest ive overclocked my gpu or ran a kernel that already has it overclocked is 250mhz. thats a 25% oc

That's the CPU clock you're looking at. LiveOC can overclock the GPU as a percentage value (ie, 110% is 200 * 110% = 220mhz), but it does the same to the CPU (so 1000mhz turns into 1100mhz). This will generally need adjusting the voltages upward.
So no need for any app to oc, just increase the LiveOc % ?
ya, that question about overclocking the gpu to higher then 300mhz was really silly, but asked t anyway
GPU Clock is stock at 200mhz, CPU is at 1000mhz. Increase LiveOC % and you'll go up by that percentage. Just remember, as i said, you will most likely need to adjust voltages to prevent instability and reboots. It's best just to set all of this up using NSTools.
Ok. I've tryed oc to 110% but instable. just need to set voltages to get the right combo.
Thanks!!
Not all phones can handle such an OC (either because of GPU or CPU, or combination, it all varies). Hopefully you can get a stable setup, the extra GPU OC is a great performance booster.

And what a performance booster... I never bothered to try the LiveOC... I just OCed the CPU and thought that was the most I can do. But with 110% LiveOC and 1300MHz CPU OC, my phone is now eve faster than before.
I have two stock Verizon Samsung Galaxy S3's. Both are running System Tuner. Neither CPU is running at speeds above 1GHz, despite the fact that each should be capable of 1.5GHz. I've tried increasing clock speed using ST and am unsuccessful. I've rooted one using the procedure at http://forum.xda-developers.com/showthread.php?t=2046439, and am still unable to get the CPU to run at anything above 1GHz. I've installed SetCPU, and still no success. I select 1500Hz, but SetCPU max remains at 1026Hz, even with "set at boot" selected and after restarts.
Questions:
- is this a limitation imposed by VZW or the kernel running on the phone?
- is it considered "overclocking" just to get the CPU to run at speeds higher than what it currently does (i.e. 1GHz) even if those higher speeds (up to 1.5GHz) are within the advertized specs of the CPU?
- what is needed to get past this? Is it even possible to increase clock speeds using the stock kernel/ROM, or is another kernel or ROM needed?
Thanks.

Never tried to OC stock kernel although some say you can if have root. Sure you are not on Power Saver mode. Will clock down to like 1100.

That's exactly what it was. I was only checking the governor settings with the CPU and never checked or thought about the Android level "Power Saver" mode. Once I unchecked the CPU box under "Power Saver", I was able to get much better speeds out of the CPU.
Thank you very much.
That's the problem. No matter what rom I flash, what kernel I use or what app I install to manage cpu frequencies, they just won't stick. My CPU is always at 1190 MHz Min / 1190 MHz Max, and when I try to change the min value, it'll only remain changed for a few seconds, then it just goes back to 1190.
Also, when I use a CPU manager app to see every core individual frequency, immediately the third and fourth core go off when I open said app.
I don't know if my device is defective. I haven't dropped it or anything, if I need to say it. Please tell me if this happened to somebody else or what can I do. Thanks everyone.
Qualcomm hard-limited the max CPU frequency in the Snapdragon 400. At least the variant used in the Moto G. You cannot overclock it.
I don't want to overclock it, I want to underclock it. At least I want to decrease the min frequency.
Ah, though I assume the same applies. The SoC won't listen to / obey requests to change those.
I have heard that it is just a visual issue. In fact if you use trickster mod or similar, you will see that most of the time the processor is not running at 1190

I think so, that sounds more realistic.
Thanks for the replies, I have found a solution after all, it was all about that thing called "mpdecision". When I turned it off with a particular CPU manager, I was able to change my settings without any problem.
Hey i have tried an app called setCPU and i am trying to underclock my galaxy s4, however when i set my CPU speeds lower i still notice the other cores of my device turning on and going above the set speed. is there somthing i am missing? or is there a way to control each core?

You are custom kernel or custom rom?
Hello!
I was searching for a kernel to flash that would be able to support the powersave governor.
But with no luck so far, I'm asking if someone is familiar with this? Seems like Performance, interactive and userspace are the only ones available after what I've found so far.
My device:
920F, 32GB
Currently running aTerminator at 6.0.1, using SpaceX kernel atm.
Eventually, are there any applications or modifications out there that would support the Octa core setup on the phone?
I've tried the No-frills and cpu-booster, but both of them only show one of the cpus, (the 1.5 ghz one) and doesn't even affect the clock rate when adjusting the settings.
My goal is to downclock the device a bit, or be able to save some more power by loading a different Governor.
Anything is appreciated, thanks!

You can try hacker kernel v13 and use synapse to underclock and undervolt but no powersave governer is available but plenty of other to try
Powersave governor isn't for daily use, it should use only for offline charging mode.

It's good enough if you're dependant on the battery life certain days I know the performance suck but it works.
Thanks for replying I'll try hacker kernel.
