I put together a simple custom voltage interface which can be used to change both the ARM (CPU) and the internal voltage. It is the perfect companion for LiveOC, but does not depend on it.
In /sys/class/misc/customvoltage the ARM and internal voltages for the different frequency states are set by passing a string of voltage values in mV to armvolt or intvolt (for example 'echo "1250 1200 1000 950 950" > armvolt').
This should work no matter the number of frequency states implemented in the kernel. This replaces the custom UV interface most kernels have implemented and both tweaks do not work together. So if you decide to include this tweak, you will have to remove the other and this will break the voltage control with SetCPU and Proton. and it is compatible to SetCPU and similar tools.
Changes to the source: http://www.pastie.org/2806507
BUGFIX:
Made Custom Voltage compatible with the typical CPUfreq UV interface (UV_mV_table) found in many kernels thus making it compatible with SetCPU and similar tools.
Bugfix: http://www.pastie.org/2806920
BUGFIX #2:
Added the entries 'max_arm_volt' and 'max_int_volt' to the sysfs interface which can be used to change the maximum values allowed for the ARM and internal voltages.
Bugfix: http://www.pastie.org/2812494
No further patches will be published here. I have set up a git repo for all my tweaks. Each mod has its own branch to keep the tweaks cleanly separated and one can simply pull the latest patches from the corresponding branch.

No more question to the kernels devs about how to activate this or this...

The ARM voltage is for the CPU, the internal voltage for the bus (and also GPU I believe). If you increase the bus/GPU speeds with LiveOC you might have to increase the internal voltages additionally to the ARM voltages to get it stable.
Made a small improvement.
Added the entries 'max_arm_volt' and 'max_int_volt' to the sysfs interface which can be used to change the maximum values allowed for the ARM and internal voltages.

[App] Spark Mod Manager - Beta 1 [5/9/2011]
Hi, I've installed ElementalX on my One and it allows a maximum GPU clock speed of 450 MHz, but I read on the Internet that Adreno 320 GPUs can reach frequencies of 500 or even 600 MHz... there is a way to enable those frequencies? Maybe a tweak or another kernel?
The s4 clocks all the way up to 627mhz via custom kernel. So. It's possible

There's a reason it isn't enabled. Don't even attempt this unless you want to melt the insides of your phone at worst case, or even in best case suffer from extreme heat and reduced battery life.

Man, heat isn't a problem for the One. HTC tests it at high temps. Mine for example is running at 2.16 GHz for a few months and I didn't have any problems at all... I reach high temps only when I play heavy games (max battery temp was 56.5 ℃)... The only important thing is that battery never reaches 60 ℃ which is the max safe temp for a Li-ion battery.

You have wrong information. Heat is a problem for all electronic devices. You will certainly shorten the life of the electronic components not only the battery if you keep them hot for extended periods. The reason the One has an aluminum case (besides aesthetics) is to help dissipate the heat from normal use and keep the device running for longer periods as well as extending the life of the battery.
Bumping up the max frequency doesn't mean the device is working at that frequency all the time. Specifically for a powerful device such as the One, it will only drain your battery faster.
Well I don't care of battery life... And the day I will notice problems I will go back to stock frequencies... So my question is: is there a way to OC the GPU to 500 or 600 MHz?
I will make a zip which does it okay? Do NOT complain when it blows up

Not necessarily. Faux oc'd the N4 GPU to 600mhz and no one made complaints due to the thermal throttle throttling the chip...QC and faux's implementations prevent excessive overheating.

Just for do some tests... And phone will not fry... The N4 and S4 have been OC'd to 600 MHz witouth any problems!
EDIT: I've tried to change the file but it resets to kernel value (450 MHz)... so the only solution is waiting for Matt's zip...
P.S.: Matt, can you make 4 zips? One for 500 MHz, one for 550 MHz, one for 600 MHz and one for 620 MHz? Or can you let me choose one of those 4 frequencies directly from a single zip? Thanks in advance.

Every phone reacts differently to overclocking but you seem pretty sure anyways keep us posted..
Sent from my SGH-T999 using xda app-developers app
Matt can you also make a zip wich unlock a CPU frequency of 2.3 GHz? Now I'm on faux123 kernel and max frequency is 2106 MHz (on ElementalX was a bit higher, 2160 MHz)... So I want to try a CPU clock of 2.3 GHz and a GPU clock of 620 MHz... don't worry I keep temps monitored and I will downclock if phone gets unstable.
@shahkam: Sure, I'll keep you posted!
Hi,
It won't work with just a zip file, the GPU freq (like the CPU freq) is hardcoded in the kernel, if you want test an higher overclock you need to compile your own kernel... It won't work just by editing a file... Try by yourself modifying the value in the path you find LOL, and there is not only this path (/sys/devices/platform/kgsl-3d0.0/*** and a few others)...
The values you'll find in certain paths are just some values matching what was hardcoded in the kernel (for to do simple).
If it was too easy to just edit some files for overclock, why devs need to compile a kernel with overclock possibility???
If some GPU/CPU freq are not available in the kernel (by the kernel dev) you cannot set them without recompiling by yourself the kernel to add some extra GPU/CPU steps.
Plus the kernel devs here have tried GPU overclock above 450 Mhz and the result was worse performance, lag, etc... Something due to memory bandwitch or memory bottleneck... I don't remember exactly...
In fact the SIV can have higher GPU overclock with the same GPU as our but the "stuff" arround is not the same. Unless a dev find the solution.
But you'll never see GPU overclock in our One above 450 Mhz just by editing some files, trust me.

I want to try myself, if it works bad I already said that I will set the stock frequencies back. Anyway I think that Matt is going to prepare a flashable zip wich goes to replace the kernel files.

LOL, good luck!
In the path you find, for max_gpuclk (and find all the others paths related to the GPU clock, good luck here too ) change the value by yourself with a file explorer like Root Explorer (edit the file) it will do nothing!!! Same thing for the other values!!!
I think you don't understand what I wrote or how all the kernel stuff works...
You need to compile your own kernel or recompile the kernel... and add the available GPU freq you want, but it's not too easy as just add a 600 Mhz step when you developed your kernel, what about voltage, memory allocated, other config files needs to be modified to match all your modifications, etc...???
It's infinite more complicated than you think...

by flashable zip, I meant I was going to compile the kernel for you ^^ But yeah the S4 has DDR3 memory so that could be the 'bottleneck' mentioned. This would be a lot of effort for little result.
I'll put more in this request thread later but for now has anyone put any work into over clocking the GPU? Like through a custom kernel?
This isnt the correct thread, there its a Q & A section.
Sayin that, you think its necesary? The phone no have any lag or something like that, it doesnt need overclocking on my opinion!
Sorry will request it be moved but just for gaming and the tiny stutters. I'd like to smooth the experience fully. I'm developing a kernel that should do so but I'm a newb so I wanted to get any advice I could. Im currently throwing frandom and smartass into my kernel. Along with over clocking the GPU like people did for the nexus 4.

I've fiddled with GPU overclocking, but it seems like Moto X can't handle even a slight 50 MHz GPU overclock. :/
I got GPU clock and voltage control to work, can be overclocked to 500mhz, anything more than 400mhz makes the UI stutter though. It can probably be fixed/tweaked easily, i won't put any effort on it because i don't use the phone as a gaming device. If you manage to fix the stuttering let me know.

That's what I got to too. Kind of a waste of time in the end since the phone is kind of unusable in the end.
I don't know if it works on OOS versions but it does, on the OB12. You need to be rooted to be doing this.
Lower the input boost to 1036 on the big and 556 on the small first. Now, change the governor of the big cluster to conservative and the small to ondemand or conservative , benefit!
To see the improvement in FPS, you need to go to developer options and switch on profile GPU rendering. For those who didn't understand this: lower the graph is, higher the fps. Hit thanks if helped

You'll see input boost in the bottom section of CPU in kernel adiutor. Core 1- 1036, core 3 -556 is what you've to do. It'll be 1324 default on both. I'm suggesting that for slightly better battery life

Lower SOTs are obvious, but to what degree is what matters. As far as I see, it's not that much.
GUYS, I recommend not to use this anymore. Oneplus has a reason to not release the kernel with conservative on . This is because conservative is not optimized for battery while interactive is. If interactive weren't optimized for battery, it'd be better than conservative for sure. I get only 4 hr sot on conservative but 5.5 on interactive. Though this is not placebo, it has a negative impact on SOT .
When I change big cluster to conservative, those cores will always stay above 2 GHz, as shown in Kernel Adiutor.

Good you realised that.. I did a little investigation on your tweak.. Apparently setting governor to conservative locks the frequency of big cluster to max possible, usually above 2 ghz and it will step down slowly ( by slow I mean really slow like 1-2 seconds). Thus causes you to have very less render times on gpu profile as shown in the xda portal post.. I opened up ex kernel manager and observed same freq in higher range.
After some time I just changed governor to interactive and changed minimum freq of big cluster to 2 ghz.. I observed the same render times as situation as time when conservative was set as governor...
So this tweak is nothing but type of placebo since ramping up freq can lead to faster processing
Edit.: Couple of people on xda portal have said the same.. I didn't check it..
How can I underclock my 9T Pro smartphone? I don't play games or use power intensive apps, I'm thinking to underclock it's CPU and/or GPU to extend battery life.
I'm on latest MIUI 11 Beta from xiaomi.eu, rooted.
Are there any apps or methods to safely reduce frequencies for its CPU/GPU?

I tried Franco's app but some CPU frequency settings don't maintain after a while.
And I'm sure I don't know exactly what frequencies should I modify (and how much) on the three clusters to obtain a balanced setting.
Not no mention GPU frequency settings...

Sorry I won't be much help on this as I haven't needed to change frequencies in a while. Afaik you just need to change the CPU and GPU governors to power save and set it to apply on reboot, small cores like to jump up a lot more max freq than the big cores so maybe around 1500mhz for small, keep large cores from going into 2000mhz and prime core too, GPU from what I remember really struggles if limited to lowest frequency, 300ish is a good starting point.
Depends on what rom you are running too, miui you don't really have a choice but to use stock kernel. On custom rom you have a lot more choices of kernel like immensity, f1xy, kraven and notkernel.

Thanks!
I'm using MIUI 11 latest weekly from xiaomi.eu.
Right now I applied your suggestions in FKM, I'm waiting to see how it influences the performance and power usage.
Well, I tested changing frequencies and governors in FKM but they won't stay after restart, even if apply after boot was checked for each modification. I guess MIUI kernel is not so friendly in this matter.

Try to use kernel iMMENSITY-RAPHAEL-V24.0-MIUI-BETA-24-03-2020 version. It's really recommend for miui11 latest beta.

Unfortunately, this kernel breaks AOD function.

I used miroom latest mi11 beta and doesn't had the above issue
CPU overclock since snapdragon 845 is not possible anymore.
For GPU try Candy.

I'm trying underclocking, not overclocking.
I am sorry I meant to say changing clock at kernel level that is.
I may be wrong though.

So, if this is true, changing freqs can't be done even in custom ROMs (non MIUI) and it's bad.
I tried lowering screen resolution and DPI to save power but the rounded corners become even rounder (?!) and power usage didn't drop that much.
