Best under/overclocking app for S4? - Galaxy S 4 Q&A, Help & Troubleshooting

Hey guys,
I want to make a slight underclock and undervolt my new S4 i9505..used to use Voltage Control for my S2 but I think that one's a bit outdated. Which apps do you guys use?

If you flash perseus kernel you'll get stweaks with it and it's pretty deep level app to o/c u/v...You can do also color calibration and sound enhancements.

SetCPU for root, is a popular one, but i haven't rooted my S4 yet so i am not sure if it works for it.

Had a look at some of the apps, it seems like none currently offer complete support for multicore power saving, like for hotplugging all four cores in the S4. Also i thought Perseus kernel was only for the Octa Core variant I9500?

Trinity Kernel...1400mhz max?

I recently flashed the newest Trinity Kernel on my Nexus 7. I still have the stock ROM. I tried to tweak the CPU settings with ROM Toolbox and the most I can overclock is 1400mhz. Why can't I overclock to 1600? Is it because of the stock ROM? I'm looking into Glazed Jelly Bean as a custom ROM but I'm not sure I want or need to use a custom ROM at this point.
Any suggestions?
Because he dropped the Max. You probably flashed A111 correct? That's a TSVZ meaning it is slightly over clocked and undervolted kernel meant for battery not for performance.

try a96, its one of my faves. it has a max of 1700mhz http://goo.gl/mLUCZ
Mildly on topic question ... do you notice any imporvments with overclocking? My first experience with overclocking as on my Hero, and then Galaxy S1, but this N7 just feels so fast i cant see overclocking making it any smoother? lol
thanks

Nice, ill have to look into rooting sometime soon.
Ok, I got the a96 and I've flashed it...
Is there a detailed changelog for each version? The a111 said it was a 1600mhz kernel so I don't understand why it was dropped down to 1400. That's where my confusion was.
I did notice some increase in speed at 1400. I was having some stuttering issues with Dead Trigger and Minecraft PE, and they were less with the 1400. I've got it running at 1600 now but I don't know what it will do to the battery or how well it will perform. I'll find out later. I've run through the battery pretty quickly today, but I was tinkering with it A LOT so it's not accurate.
What kind of tweaks could I do using Rom Toolbox that would help me maximize my battery while overclocking to 1.6?
Dont over clock.. i dont even see a need to. I use the ondemand gov which stutters a little but using interactive clears that up. Also using the CFQ IO as it is the stock IO used. Its stock so its gotta be good . Also you should turn F-Sync off that helps quite a bit. Also you could toggle auto hotplug and make it only run two cores while gaming and then turn it back on when finished so that way it will hotplug cores as it sees necessary. You could also up the voltages a little bit, some CPU's dont like the lower voltage and that will cause stuttering and glitching just up them by 25mV and see if it clears if not try another 25mV.
I will try those things, but I really want to play with overclocking and learn what happens. This is my first Android device so I'm experimenting and playing around.
But I have one more question...I've overclocked to 1.5...I found 1.6 to be the same as 1.5. But it seems that after an hour or so, it resets to 1.3. in ROMToolbox. Why is this?
Don't use rom toolbox. Use the Trinity app. It sticks just fine for me. Besides you support the dev to make better kernels.

youre not the first
Overclocking past 1.4 Ghz doesn't result in any major usability improvements. I've gone up to 1.7 Ghz and the only thing it does is make my tablet really warm and unstable. All you really need for improving system performance is I/O tweaks to speed up app and page loading, and a little bit of GPU overclocking to help with the transitional effects.
and, to be honest, depending which trinity kernel im using, im using either 1100 or 1150mhz mostly. on a111 im using 1100mhz and on a96 i used 1150mhz. with those speeds everything is still fast but a bit better on battery

If you want a little more information about the the overclocking if you havent already you might want to check out http://forum.xda-developers.com/showthread.php?t=1788759 its the official thread of the trinity kernel for grouper.

[Q] S4 i9500 Slower after using "Adam Kernel", Why?

Hi every one,
I tried to post this to the main thread of the kernal, but i could not since i am new member.
I just flash my new S4 I9500 to "Adam Kernel".
Main thing i noticed that the phone respond was better, and i really cant judged about other stuff since i did not use it.
But when i tired to test the phone with Antutu benchmark, noticed that the score was dropped from 281xx to 276xx, even when i am using the Performance instate of on-demand or other battery save options.
I hope if someone can help me to understand this.
Thank you very much,
Emad

i don't see why you should be upset over benchmarks.
Benchmarks *can* give you an indication of performance, but *nothing* is better than simply making your own objective decision.

Hi,
Thank you for your reply.
Actually i am not upset quz of the benchmark result, all what i want to know in that case, is the new kernal give me less cpu power that the original?
I am only wondering..
Thank you,
its probably due to Governors change.
Adam kernel tweaked cpu governors to be power a power saver than performance. if you have Wanamlite rom you can manualy set cpu governors so you will see better benchmarks

Set CPU for Root Users

Has anyone used this application on this phone? I was thinking about undervolting and maybe even under clocking.
In my experience if you are the kinda person that wants to overclock/underclock you are usually the same type of person that would flash a different rom. Now days most ROMs have great CPU options

PIE control
Most important one.. Stability. Needs to be stable, and have a few minor tweaks, it all depends on how the stock kernel is though.. HTC Stock kernels tend to be pretty sweet anyway and just need a few features added IMO.
Have been told that the CPU is way under clocked @2.3,GHz and could handle 3.00ghz easy! Note that this is a rumour, but if true wow!
Really looking forward to it now!
Um everything you listed is stuff that is the norm for custom kernels. Wonder if well see Franco or faux or flar here...im still really on the fence.

At the price probably only if the device is donated. I'm sure the size is off putting for them.
USB-OTG and USB-Audio support would be stellar (if not included as standard)
:good:
I would love to see the GPU and CPU overclocking as well as over/under volt for both for maximum tuning capability. The other things I would like to see though are RAM and bus overclocking access since with so many GPU cores if we get to overclocking we may need some more in those areas too so we can take full advantage of the higher core MHz

Why isn't anyone overclocking?

Hi there,
I'm really loving xda for years cause the active community here (depending on the device) and love to overclock my phone.
Through the years I've oc'ed it all starting with my HTC legend.
I know that it isn't just adding some freqs and voltages to make this happen, but I don't understand why (kernel)makers don't oc the S8. For example, I see som kernel developers build kernels with oc/uc and voltage control for the S7 (exynos). Some of those developers now build kernels for the S8, but don't add any oc possibility.
I just don't get why and am really curious if any of you understand why?
It's not that I'm not grateful for what they do (cause they are awesome) but I'm just REALLY curious and can't find the reason why it shouldn't and/or couldn't be done.

Well the snapdrag version can be underclocked but there is no OC as the kernel is not modifiable Due to locked BootLoader

Sorry I didn't specify things. I do mean the exynos version. There are some kernels that lift the 2,3 max freq to 2,65 GHz, but know that some S7 kernels climb to 2,9 GHz. So (in my book) that means the S8 should be able to overclock to 3 GHz (cause of the base A73 base of the 2nd gen mongoose cores and 10nm footprint).
So I'm just curious if it's not possible or there is some other reason why none are doing this.
And with underclocking I meant adding freqs that are below the standard lowest freq, my bad. (Don't how to call it otherwise)
Battery life.....
Battery life mainly.
Through overclocking, sure you can make s8 run as fast as oneplus considering s8's heavy skin, but most of us would rather see 6-8 hours of SOT with 24 hours of usage than our app opening 1-2 seconds faster.
Saying that, there are plenty of debloated roms for s8 that can run faster/smoother than the stock without sacrificing the battery life.
So, as for your question, maybe the devs don't want to put too much effort on overclocking an already pretty fast processor or underclocking an already pretty efficient processor. I am not a dev so can't really talk about complicated codings and stuff.

The S8 is fast enough on its own. I never even OC'd my S6. I find Exynos processors to be really fast as-is.
It's true, I dont't see any practical use for overclocking, yet. It would be purely for the fun of it. I'm sure we will see it more in the future, when some more hardware-heavy Games will be released.
Undervolting on the other surprises me aswell, to not see it frequently. Because, although it's totally fine right now, batterylife and efficiency can always be better.
I'm curious if we will see more Devs include this in their ROMs and Kernels
I agree with all the above. I called either due to snapdragon but I wouldn't even i if I could. I actually limit the clock speed on my big CPUs because the higher clock rates eat more power.
Also, why? Just why? Looking at cpu usage on my s8, the only time I've seen it actually pegged was running benchmarks. Overclocking is absolutely useless if the variable cpu clock never goes to 100% for more than milliseconds. Why do something so potentially dangerous for nothing?
:good::good::good:Well put guys:good::good::good:
I cant overclock but i still have set cpu and use it to underclock (when the screen is off) but most kf the time it is underclocked if it is not playing a game or ram extensive app

Why you overclock GTX 2080? Why you overclock i9 or amd threadripper 2950x cpu? Why you overclock DDR4 3000MHZ Ram? Why you use 3DMark? Or cinebench or, or or........
Thats all the same.
To everyone asking "Why??", I find it rather odd that you don't know already...
The reason why some of us like (want) to overclock, or undervolt, is the exact same reason we're all on this site: We like to TWEAK STUFF!
Doesn't matter if it's rooting, flashing a custom ROM, creating a unique theme, coding a new app. All of those boil down to the same human instinct to explore, to make things better, or make new things. Whether or not it's needed is completely irrelevant
Using your logic, there's no reason to have a custom kernel in the first place, nevermind rooting your phone, or having custom ROM. The phone worked fine the way it was, after all, right?
In closing, the motto "If it ain't broke, don't fix it" is what the lay people adhere to. We who are more inclined in certain aspects of life (such as the XDA community) live by another: "If it ain't broke, tweak it!", or if you rather "If it ain't broke, tweak it till it does, then fix it!"
Please add over/underclocking and over/under volting for CPU and GPU cores to every kernel, for every device that allows it! We already except blame if anything bad should come to our device the moment we decide to root and/or flash something, so why not give us every single capability available for the devices and leave it up to us to do what we so choose? :good:
[Naturally, this is based on the assumption that a device lacks a bootloader, and the kernel maker possesses the knowledge; thus, this is referring to those situations where both apply.]

To be faster than other team who is performance tuning as well. You don't have to do it because not everyone is doing. It should be geared towards to people who really care. Like others in this thread mention battery life but people like me wants it faster.
Also I game with the phone connected to charger all the time. I don't really game on the go though if I did I would bring portable battery if someone driving me. That just me.
People like me use phones for emulation. GameCube games are almost at the right speed but do run just a bit to slow in some location rendering them unpleasant to play. A bit more of cpu power would certainly make " Wind waker " run at constant 30 FPS. I hope this topic to be revived
Well just a quick answer , it's because of how samsung's voltage table is set , the voltage table is locked and to be modifed it needs to be hacked in some sort , that's why you cant oc that much since you need to change the voltage table and increase it so you can have stable oc
Addition:
There is alot of kernels that has oc already gpu and cpu wise , they add like 200mhz oc or something for cpu and 100 for the gpu yeah that would give you that little bit of extra juice but it aint stable in some sort you can have kernel crashes or system hogging that's due to the voltage table , i can make you a kernel that has 600mhz oc but ass soon as you select it , the phone would crash since it doesnt have enough power going to it
As Xperia modder said, darn LOCKED voltage table. If only it was unlocked....
