In theory, sure.
In practice, I don't think it's sustainable. You could modify a kernel and try for yourself! But overclocking your cpu is going to degrade it, and the gain wouldn't be that noticable. Also it would be pretty unstable I suppose!

I would encourage you to do a little more research into overclocking. Some kernels allow up to 1190mhz through setCPU and i have played games at this speed - so for real life use that speed has been stable. A thorough benchmark will better test the stability, but only if you raise the voltage will the CPU's life be effected, but if by only a small amount then you will probably upgrade before the CPU is anywhere near giving up. I do agree with the post above that there will be little noticable change in experience, but this will show in benchmarks.

Read my thread dude
As many of you may have heard, Nexus 7 overclocking became very successfully. I was wondering about the status on overclocking the frequency on the Nexus 10. Is there a good kernel out there now or in the future?
Thanks!

Did you bother to check the dev sections?
There is at least one kernel out that allows overclocking, mine was very stable at 2.0ghz ...
You should have searched around more. But as of right now, the Nexus 10 can get overclocked to 2.1 ghz without much stability issues. The biggest issue is that it thermal throttles so the performance increase isn't that big compared to what it's supposed to be.

I don't understand what CPU bottlenecked means... sry...
Also, I did look around for the kernel guys. I'm just not sure can I flash the kernel over the stock rooted romor do I have to flash both kernel and the AOSP rom.
Plus, I just wanted to know some progress because overclocking hasn't been a big topic for Nexus 10.

P.S DALINGRIN, I REMEMBER YOU FROM THE NOOK COLOR COMMUNITY!!!
FIRST ROM FLASHED WAS MADE BY YOU!
lol
CPU bottleneck just means that CPU is the hardware component that's slowing down the device. But in the Nexus 10, CPU is not the bottleneck (CPU is plenty strong). The Nexus 10 doesn't need any CPU overclocking. It needs memory and GPU overclocking.
You can flash the kernel over stock rom.
Hi,
I've noticed a huge performance difference between kernels and the roms they're used with.
For example:
I was using AOKP and Franco kernel and got around 20000 antutu points, I've switched to Carbon Rom (because of the build in pie control) and Franco kernel and only get around 13000 points, that's a huge difference.
As a test I've installed Matr1x-kenel on Carbon and get around 21000 points.
I really like Franco-kernel and all the tweaks it offers but don't like the huge drop in benchmarks, I know benchmarks are not a real representation of actual performance but it's still a big difference.
This also occurs in Quadrant and Geekbench.
So my question is why does this happen?
Aren't most roms supposed to be compatible with most kernels?
Thank you in advance.
Best regards.
I can't answer your question as to why that happens (no doubt someone else will) but you seriously should just stop bothering with benchmarks and use your own eyes and experiences as a measure of how good a kernel/ROM is. I doubt you could find a kernel which made the phone visibly slow or that affected usability so I don't see what your concern is tbh.
Thanks for your answer.
Yeah, I read that a lot on XDA, don't trust benchmarks...I understand that but they must have some meaning.
I mean, if not why do they exist or do people bother using them?
To be honest I don't really notice any real performance difference between most kernels I've tested.
Best regards
some roms include many optimizations(like skia/dalvik, krait optimizations, and others), while some dont. its not thekernel thats crapping out on you, its the rom.

your eyes can be decieved.. they can see whats happening in the ui for example, but you can not see the complex calculations that are being performed or how your cpu is really performing. you can have a slow device whos ui is quick.
OK, I can understand that not all roms are equal but why does changing the kernel have such a seamingly big impact?
If a rom is bad to begin with it should stay that way no matter what kernel you use with it.
Offcourse what do I know, I'm not a developer so my knowledge on the subject is limited.
I'm just trying to understand what's going on...

kernels vary too, and they impact greatly because they control just about everything in the phone, kinda like a brain. since the kernels themselves vary, one kernel might be better set up than another to deal with certain code from a certain rom. and then also, every phone reacts differently to each kernel(and roms to a point). thats why its recommended to try out different kernels, combos. only then you can find the perfect combo for you/your device. what works great for somebody, can be lousy for another.
OK, so if i understand correctly it boils down to this:
1. You can do benchmarks but don't base your opinion on just the benchmark scores.
2. Roms can vary greatly in optimizations and efficiency of coding.
3. Kernels can also vary greatly in optimizations and efficiency of coding.
4. There's no such thing as a "best for everyone rom/kernel combo".
5. Not all roms/kernels play equally nice with each other.
6. Play around with as many roms / kernels as possible and decide what works best for ME based on MY experience.
Thanks for the advice.
Best regards.
Its been well over a year since I ran any benchmark of any sort but I tested Franco and carbon because that's what I'm on and you mentioned low scores. I'm on Franco m3 with some tweaked settings and carbon nightly from 7-5. Antutu gave me 20636. I'm using stock CPU and GPU frequencies.

Maybe the nightly Carbon rom is more optimized?
I'm on Carbon 1.7 Stable and used Franco nightly 162 to test with.
When I benchmark I try to be as consistent as possible ie same temperature, performance governor, airplane mode etc.
I even cooled my Nexus in the freezer for some minutes to eliminate thermal throttling (yeah I know, watchout for condensation) but still got the same low scores.
Best regards.

It might be, I didn't do anything special. I left all my background apps running, didnt close anything in the recents, didn't cool the phone first. I just downloaded it and hit start. I use the interactive governor tweaked a bit, and I also tweaked the hotplug settings so it more readily onlines all 4 cores instead of waiting for some of the higher loads to trigger it.

Well, I had to try it myself so I did a factory reset, cleared system,data and dalvik, installed latest carbon nightly.
With stock kernel I almost reached 21000 points, with franco I barely get 17000 points.
Very strange...
edit:
I stand corrected, did a second benchmark and am now getting 20880 points...
are you benchmarking with your cpu speed benchmarked set as highest and lowest cpu speed? you should. if you dont put the same cpu speed as highest and lowest then itll scale up and down. if it scales, you dont actually know what speed its testing and it gives you inconsistamt scores. you want the cpu speed to be the same throughout the test.
When I benchmark I set the governor to performance, this should keep the cpu running at maximum speed without scaling unless I'm mistaking...

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

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....
