GPU overclocking kernel request - Sprint Samsung Galaxy Note II

Found this in another forum. Wanted to get exposure to the possibility.
http://forum.xda-developers.com/showpost.php?p=30087853&postcount=2
From another poster: He references using "siyah" kernel in his S3, which appears to be an international version with the same processor as we have. He indicates the need for "stweaks". He talks about GPU "steppings" so I'm not sure if Andrielux has changed these in his kernel. I installed the app "stweaks" but it wouldn't load as it said "no kernel support".
Wow!!! What in the world. Is this for real? I wonder how stable it is. From 440 up to 800?! They are using some app called Stweaks (and the kernel of course) to do it. Love to see that on our Note 2.
And since it seems that the GPU wasn't changed much....from the Galaxy s2 series... "700 Mhz - 1100 mv" is only 75mv higher than the stock 440...and accoring to the forums stable. A 70% increase in speed and stable. This is a must have for any newer kernels.

His kernel does have it. Read the n7100 thread for directions

"his kernel". Can you be more specific? Do you have a link to this kernel that we can use on the Sprint GSNII that supports GPU OC?

It's about 1/3 the way down the OP with a beige arrow and a GPU frequency table. The few paragraphs below explain how to overclock the GPU via adb/terminal.
** Edit: AndreiLux just posted a new update which includes STweaks support.

Perseus kernel supports GPU overclocking now using STweaks. And it FLIES. Wow.

Stweaks slow overclocking but if you OC it by 100mhz laugh amd giggles numbers. What kind of actual gpu performance are you getting. I see with.stock better real life performance.during.gaming versus his kernel. So if I were to oc just to match stock is pointless to me.
why overheat the gpu when I can get the same performance on stock kernel.
It has to be the way he has it coded. Till it matches stock and further progress dev for it ill step in. I do appreciate his work and time. But for me I need something better than stock. I got this phone for a reason haha.

What kind of performance? I beat the Nexus 4 as the highest rating 3D for a GPU in the market on Antutu. And it's noticeably different. Fun for extrme gaming I guess. But it affect the entire speed of the phone too.
Did you try it yet? The kernel is EXCELLENT. Going to donate from my next paycheck to dev. Thanks again.

NFSMW, GTA 3, Heavy Gaming. I noticed it was bleh on the kernel. And stock was virtually amazing no fps in fps either even during benchmark. On his kernel the 3d test for quadrant ghe fps dipped below than 58 which was consistent on stock

Strange! I'm on Project ROM Ultra lite 1.2. Have you tried N.E.A.K? He said his kernel is set to 700mhz already (no need for STweaks). Can you test that one?

Why would I need a kernel to overclock the gpu to match stock gpu clock from stock kernel to get same performance performance. Neak is on the s3 not Note 2 unless he or it in that Rom but still.
I want a custom kernel that can match the GPU performance on the stock kernel without the need of overclocking

Should we test it? I asked him if it will work on the Sprint version of the Note 2. I can't imagine why it would not.

FYI, STweaks is working for the Perseus kernel as of build 27. My GPU is currently at 733Mhz and I've undervolted all settings by 25 - no issues.

Yep. Seems like a very stable kernel to me. But the guy above is saying that the kernel has low framerates compared to stock. I am hoping he will test the Neak kernel out.

Sorry but I will not ill be sticking to stock maybe in the future. That kernel seems weird not sure which to choose. And like I said, I don't see the point of downloading a kernel know that will I will basically need to overclock the gpu just to get the same performance as I would on the stock kernel.

Best route for overclocking with CM10?

This is my first rooted device and I'd like to set the CPU frequency higher. I've read that 1600 is moderately safe and 1800 is feasible. After installing setcpu I've realized that CM10's kernel does not allow overclocking. What is the best action to take? Am I out of luck if I want to stick with CM10? Or is there another kernel I can use compatible with CM10? Thanks for reading.

Try kt kernel in original development, I've used it with great success. Has oc up to 1.89. Also allows you to under volt to save some battery. In conjunction with ktoonz kernel get voltage control from the market to adjust cpu clock and voltages.

Thanks for the suggestion. I used Leankernel all day without a single issue that isn't specific to CM10 right now.
P.S. I also upgraded the modem to I747UCLH1 from this thread. To anyone interested, test your data speed on all three modems to find the best one to keep. My rates doubled with this new modem.

Hey this might be a bit late on this thread, but Siyah has just released an updated, which works with cm10 and allows for overclocking up to 1600, and undervolting to save on that ole battery... currently for the galaxy s3
Obligatory reminder:
Not all phones are the same. Some tolerate overclock/undervolt better than others. What you WANT your phone to do may not actually be what it WILL do. Start slow, only change one step at a time. I would recommend finding the perfect oc point for your phone, then slowly, slowly working the undervolt into it.

Cyanogenmod 7 and 10 overclocking questions

hi i'm looking to overclock my sprint epic 4g cpu up to 1.8ghz and also the gpu to 300mahz and 72hz refresh rate
on either cyanogenmod 7 or 10
what kernel and ROM and CPU/GPU overclocking apps should I use with voltage control and what (safe) voltages should I try for the cpu and gpu ARM and Internal voltages (what build number do I need for cm 7 or 10 (either stable or nightly)
also I noticed that the slide out keyboard shift and function keys don't work on cyanogenmod 10 stable build not sure about a nightly build
I'd like to fix the keyboard too
i'd like to be able to turn the boot logo on and off and possibly change it to a different one and also add a boot up sound to the logo
should I use the franko or samurai or maybe a different kernel ?
what modem should I use for max speed (EL30 FC09 FC19 or Nexus LF2 K2 ?) and compatible rom
I know how to install everything just need advice
If all of the above isn't possible at least I'd like to get the CPU to the highest possible speed past 1.2 ghz if possible most of all and not have random reboots or lockups or sleep of death and woking keyboard and least amount of bugs in the rom
Thank you so much in advance for any advice
Do your shift and Fn keys work if you hold them down when using them? Kind of like the way you would use them on a PC keyboard?

Last thing I know of that had what you're looking for is CM9 with Samurai Kernel. The processor clocks to 1.5 Ghz and I believe the gpu is overclocked to 400Mhz. Idk what the refresh rate for the screen is, but that combo would probably be the closest to what you're looking for

^^^^this... there is no franco kernel here, that's for the epic touch... nobody has been able to overclock this phone past 1.6 Ghz... samurai had 1.6 at one point, but it was removed because there were stability issues with most phones trying to overclock that high... samurai has always been my favorite kernel from tw gb roms all the way to cm9... sadly development stopped when earthbound upgraded and there is no samurai kernel for cm10 or 10.1... everybodies phone is different and handles overclocking differently... best bet is to just keep trying combinations until you find your perfect match...

I have used it on CM9, and got it to 1.4 comfortably, but the kernel itself was quarky as hell. The battery died when unclocked and- just all in all at bad kernel.
im curious on what he did to make it do that though. Was it an app he combined into the kernel? Did he expand something?
Technically- OC"ing is just like any normal OC. INcrease the multiplier or frequency and then manipulate the voltage to handle the work. But- THe couple app i foudn that do that- like uh... setcpu, targek or something all arent supported by our rom/kernel/ something. Its rather frustrating.
With the Packman ROM im using, he combined the Performance control into the rom, and you can actually change the voltages- but.. i cant make it go faster.
TO go on with that- i still cant find a way to OC the GPU. i see people saying they got it up to 400mhz. or something. But- HOW!? an app? Kernel again!? heck, i dont even know what the stock settins are. :/
GPU overclocking is achieved in the kernel.

1. He did it by being a kernel master... 2. they aren't supported because of the kernel you're using. 3. And again, the kernel you're using. The only way to overclock the gpu is with the samurai kernel.
4. And most importantly, for everything you want out of a kernel, it's about time to learn Linux and build your own kernel...

Aww man I miss Samurai's 400MHz GPU OC... But the Voodoo defaults there is VERY terrible... Just why isn't there a kernel with ONLY GPU OC (i.e. no CPU OC up to like 1.4GHz (I think games depend more badly on GPU) and no Voodoo and such)...

If you build it, they will flash it!
Yes, for those looking for an easy way out, it's not going to happen. Learn to make a kernel then learn how to manipulate the settings. If it was easy then everyone would be doing it. No one has any other spoon fed answers.
I think not having an easy way out may be the definition of xda-developers. Forget where I read it but it's about the journey rather than the destination, which I know doesn't hold true for every one but I know it does for me.

It's more based on how the rom works, and the kernel yes helps with CPU and GPU scores but I noticed his GPU scores are lower than mine, one of the nation reasons I'm still stock. Because it's probably persues kernel and has issues with FPS in real world and quadrant performance.
He probably ran it 1600/1600 on performance or something on those lines
Edit: this is mine stock rooted GPU much better than his, until persues can match this without overclocking the GPU just to get the same performance I do on stock I'm not switching.

Maybe you should consider that you're not the brightest, most experienced person in this thread before talking smack.
Exposing a component to more heat means you are shortening its life, there is no doubt about that. Those with overclocked desktop CPUs often have elaborate setups with overclocking in mind. You can't add a better heatsink, or a fan to your phone. Mobile CPUs, especially, are designed to be efficient at a certain range of clock frequencies. Moving it too far from the norm means you eventually see diminishing returns.
I've fried everything from my first Commodore 64 to my current box, and everything in between. If you think the phone can function at that level for an extended period of time without failure, best of luck to you.

Dude it was part of the whole meaning of rooting and tweaking. Checking different settings for a little bit, testing them and then reverting back to defaults. I will never leave overclocked/ undervolted or vice-versa settings for a whole day... its just part of the fun of tweaking and experimenting with our devices...

I am all for overclocking, modding, tweaking, hacking, etc. Breaking **** is the best way to learn. But that doesn't mean you should push your hardware past the point of exponentially diminishing returns, and increased risk of burning your chips out. That is, unless, you have no problem with the very real possibility that you'll need to buy a new phone.
That being said, kudos on "going plaid" with your Quadrant score

[Q] kernals for GPU OC?

Hey. I'm using the rooted stock jelly bean ROM with KT747 on my i747m. I'm wondering if there is a nice stable kernal for the i747 on stock ROM that would allow me to overclock the GPU a bit. I got my phone stable 2.1GHz at 1250mV and now the GPU is really holding me back in NFS:MW, dead trigger, NOVA 3, etc.
Is 2.1GHz at 1250mV a good OC? I noticed the default voltage for 2.1 was much higher. I had it stable at 1240mV (tested with setCPU, antutu, stability test 2.7) and ran it all day without any problems but I bumped it up 10mV just to be safe.
Thanks.

That's definitely strange. How would raising clock speeds hurt/not do anything? That seems pretty ridonculous.

Any GPU Overclocking Kernels for...

I recently flashed the KT747 for a super fast 2.1mHz CPU overclock. But then after flashing I realized it doesn't overclock the GPU that much.
Are there any kernels that can overclock the GPU to about 700mHz?
-Thanks for any help!
Sorry for CyanogenMod 10.1 (d2att) nightly ROM.
Does the new SiyahKernel work with the ATT Galaxy S3 running CM10.1 nightly?
Ah stupid me I meant 2.1ghz or 2106mHz CPU overclock.
I don't think any kernels do GPU OC, because it has shown to cause more problems than it is worth. That's just what I remember KT saying.

Most custom kernels if not all already have GPU OCd to 450mhz
Over clocking the GPU on a GS3 is not needed and even with it over clocked, you wouldn't tell the difference. It also leads to issues and battery drainage.
The S3 doesn't need OC at all 1.2Gz with 2Gz of ram leaves no place for lag.

I haven't had any lag whatsoever at any point that I've had my S3. Try reflashing your rom and completely wiping. Also try a different kernel and kernel settings.
This phone shouldn't lag at all. Maybe a little on TouchWiz but never on AOSP

My s3 lags at 2.1 GHz too. Try it at 1.6 or 1.7 GHz or change governor settings to a faster ramp up one.
