Is there any way to overclock the GPU and/or memory inside of a rooted and rom'd Verizon LG G2? I want to squeeze every last drop of performance out of the Snapdragon 800.
Any general performance suggestions?
Thanks in advance guys!
Hi, which rom and kernel do you use?

Hey there, I'm in the process of updating to the latest Vanir build and the 8.0.1 Dorimanx F2FS kernel.
Till now, there has not been a way of overclocking the GPU of the LG G2.
But honestly? It would only cause the overall performance to drop. The G2 already has a hard time getting rid of the heat generated when running at 450 Mhz, so overclocking it would just generate more heat which, in the end, would result in an even more aggressive throttling.
With Dorimanx kernel, you can OC the GPU to 450Mhz, if I'm right the RAM frequency is not OC.
Then, there is a lot of tweak with STweak and Synapse.
The best thing that you can do is to try
I use it every days with the CPU @1.9Ghz and GPU @320Mhz without any lag.
I guess you will not succeed with F2FS... Not working for now.

My bad, you right, 450Mhz is the stock frequency.
Thank you for the prompt replies guys!
It's a little disappointing that those overclocking options are not available but this phone is still a beast! I was curious about those options as I am envious of new mobile chips such as the Snapdragon 805, 808, 810 and the Tegra K1.
It's the natural cycle for a phone. It's hard to admit and accept but that's how it is. I can't wait till there are more options of phones with 64 bit cpu.
BTW, 808 and 810 aren't even out yet.

So I was thinking the other day, my buddy has a Samsung Captivate which I believe has the same CPU as our phones, yet they have a much higher OC (up to 1.6ghz I believe). Got me thinking whats the highest we can get our devices stable to?
I tried 1.4ghz and failed, device almost came to a standstill. Honestly I'm not so sure its the processor as much as the stepping. Why do we have only 5 settings for stepping in Nook Tweaks? Is it a kernel limitation?
Anything above 1.2 won't give you any added performance... Something to do with it messing with the GPU.

Don't know about phone but for NC, anything above 1.2GHz is asking for trouble rather than performance.
Ok guys , i want you to know that the exynos 4412 present in the s3 is a beast i will be writting all about it here !!
Hope you like it ..
Exynos 4412 is a quad packed cpu package with clock speed 1.4/1.6Ghz , has an architecture of cortex a9 32nm which was one of the most powerful architecture at its time .. It is accompanied by Mali 400MP4 clocked at 533Mhz , which was specifically made for 3d processing.Those four cores support up to 128-bit instruction internally, double what the previous Exynos supports. The chipset also has other potential advantages like USB-on-the-go, USB-host and -device regimes, as well as a number of other options, including the ability to connect up to four memory cards.
So , by now we get the image that this cpu is still a beast . But what about battery efficiency umm..
There come the Hot Plug functionality which has the ability to use any of the 4 cores at any clock speed and also has the ability to switch off its cores anytime it wants according to the user demand ..
So as we have 4 cores , when doing not so heavy work then only one core will be activated hence using a lot less battery as compared to other cpus . As said by samsung its 30% more efficient than exynos 4212 found in the s2 .
Also the cpu has a dedicated image signal processor for better image processing thats why s3 still has an awesome camera ..
If you want to know anything about this cpu ask , i will try to answer it .
why does it lag
Exynos 4412 is several years old by now and not in the least an interesting chipset.

Lol , the thing is that samsung apparantly bloats our touvhwiz roms and also when running a cuatom rom it does also because our complete sources are not available...hence making it a bit laggy..
Had our sources been available w Be would defeat nexus 4 in performance is custom rom stability.
I use a rom on my s3 which gives me 30k on antutu ... Thats better than snapdragon 600 ..
You wanna know how ???

How is it that it gives you 30k on antutu ??
Mine gives 26616 on antutu i am running aosp neat rom 4.4.4 with a archi kernel without any overclocking....
Why does Samsung underclock it to 1400Mhz, when it runs stable at 1600Mhz? GIVE THE PEOPLE THE SPEED!!
Because it will get heated fastly and the battery life will degrade very fastly

i roxk back to noot v6 + archi kernel 1.7.2 , cpu oc to 1.6ghz and governor set as zzmove battery plus , which uses our hotplug functionality to the best .
also i have zram enabled to 2 devices with 400 mb each that does for me .
you try out these tweaks you check what scores you get i am sure you ill get 30 or 29k
as i get 29k and sometimes 30k
if ypu want lollipop then nameless 5.0 by dhiru gives 30k pn antutu as well you might want to look into that

Our cpu can be safely clocked to 1.6 i recommend that too but i recommend it using along with zzmive battery plus governor which will not let your device heat up and even give bettery battery than pegasusq , oc it to 1.6ghz with zzmove battery plus i am sure you won't have any problems with power as well as battery !!

Thanks so much for posting! Well it means some people (with higher AVS groups) can possibly overclock/undervolt better than others. For example i can apply a -75mv undervolt to all the frequencies and achieve perfect stability. Also i can overclock to the full 2.4ghz and it will reflect in everything from geekbench to antutu scores and all this while maintaining the same stock coolness of the phone and battery performance.
I m curious to see if there s anybody here with an AVS group of 10 or above and see how well they can overclock/undervolt and generally speaking perform as far as scores and battery life goes.
For example this is how far i could push with perfect stability this phone while undervolted @ -75mv - http://forum.xda-developers.com/showthread.php?p=63589738
Also the battery performance i got with 2.4ghz a57 cores and 852mhz gpu clock - http://forum.xda-developers.com/showthread.php?p=63750002
And with 1.3ghz a57 speed/420mhz gpu speed - http://forum.xda-developers.com/showthread.php?p=63851201

Thanks in advance man and congrats for an awesome device!
However, it doesn't make any difference except the lower temperature. The power drain of this N920I is similar to another Note5 Which is N9200 with 7 7 7 7 8 7 avs profile. And the score of N920I which can reach 67xxx-68xxx is just a little bit higher than the one of N9200 Which is within 65xxx-67xxx

Where do you find "Info" in Synapse? The only choices I have are: A57 Cluster, A53 Cluster, GPU, and Busses. I'm on Arter kernel...
First root ur device, then use an app call Root Explorer to check out /sys/kernel/debug/avs summary.

I've been having pretty decent success with overclocking (1.5 and 2.4 GHz) and significant undervolting (-50 mV). I could undervolt less, but I was getting some issues (freezes, rebooting) so I'm happy with where it's at now.

PCMark. Developed by Futuremark.
I've only made small changes like I described, no fixed max frequencies for example. I get a Work score of 5700, so slightly higher than stock. I will say the Gundal Kernel makes the phone run notably smoother.
By the way, doesn't fixing the clock speed kill the battery life or make it run very hot? Surely you only do that for the benchmark right?

So I installed Kernel Adiutor to tweak the I/O performance and was kinda curious about the governors and all. I noticed that all 4 cores stay on at ALL times. Is this normal behaviour? Why is there no hotplugging? could it be implemented in a custom kernel?
Coming from a Snapdragon 801 which had quad custom cores, it used to have hotplugging to save battery. Thanks for answering if anyone knows

My only guess here is probably the Developer haven't add support for the new'er Snapdragon chip/s?
Been using Kernel Auditor for awhile and I see sd820 reads as single cluster where should 2 (big-LITTLE) . Well just a thought
ok that makes sense, do you know of a kernel tweaker which is updated to work with the new snapdragons by any chance?
I found an app that works, for anybody who is interested, EX Kernel manager works great with the big.LITTLE cores on the s820, happy tweaking!
I'm currently trying out the Interactive governor tweaks posted around the forums
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
