what kernel can i over clock it?

hey everybode!
i wanted to know i have rocket rom and i want to use setcpu to overclock my kernel
and sebastian is max to 1400 is thers good kernel that i can play with it till 1700mghz or 1900?
but it need to be stable

Abyss goes to 1700. My CPU can't take it, sadly

The stability is dependant on your hardware; some chips can only overclock to 1500Mhz and some can overclock all the way to 1900Mhz. It is not something the kernel has a say over.

Don't all of the notes have the same cpu? Why can some be overclocked and others not?

They all can be overclocked, but how much is a different thing altogether. It's quite simple really, not every chip manufactured is of equal quality; some chips have more imperfections. The more imperfections the less it can be overclocked before it becomes unstable. It's the same thing as on PCs, too.

Stable is it when you do nothing and use it in originally form. Overcklocking need more Power more power is less time you enjoj your note!

Generally these chips are made to tolerate a certain speed, and because of variability, the manufacturer drops the speed tolerance to ensure overall quality. Some will still be able to manage 1500, 1700, or even 1900 (although rarely, I'd say). Just about all of them tolerate 1400, so very few are defective at the stated tolerance. With 5 million, you will get a few, however.
This is one of those rare occasions when statistics have a benefit in the real world!

There are many out there that will let you overclock. Search the Android development forum.
Like most, I have flashed heaps of times, probably at least four or five times a week when I first got this wonderful Note, but in the last month or so have only been tempted to stray three or four times. Personally Franco 6 is best for me, because I favour battery life and stability rather than overclocking (1400MHz is not bad as a standard!!)
I would encourage you to try a few for a few days, as long as you backup often you should have a great experience!

Are all kernels capable of overclocking?
Is there one that overclocks the best?
How do you tell how high you can go?
Do you jusy keep overclocking until the NOte stops working?
If so, there must be a fine line.

Stock kernel isn't capable of overclocking.
One way to tell is to download things like SetCPU which detects the range of the clockspeed. Another way is to simply read the description of the kernel thread.
How high your phone can go is an individual thing. You need to overclock in slight increments (say 50mhz at a time) and run a stability test to see if the phone crashes or not.
You DO NOT pull the slider all the way to 1.9 ghz and "see" if anything happens. If you fry your CPU, do not come to us for help.
This is why I don't like overclocking, it's a waste of time to run the stability tests, etc.
In summary, you need to raise it a little bit, and run stability tests and repeat the process until your phone crashes. At that point, you'd know the last safe-stable clockspeed that your CPU can take.

Thanks!
What do you recommend for a good stability test?

I'm on franco.kernel v10 and OC to 1600 using Tegrak. Tegrak runs the stability tests automatically and reverts to stock 1400 if unstable or a reboot occurs.
I tried 1700 but Note rebooted after about 2 minutes. Booted right back up at 1400 with no problems. Re-set to 1600 and running smoothly.

Xperia z Antutu varying benchmark scores

Antutu benchmarks score gets reduced after installing the latest update from Sony.
i have run the benchmark soon after unboxing the device.. and it gave me a score of 20707..
and there was an update from Sony which after installing for some reason locks the processor speed when its heated up.. when i run the benchmarks now it gives me a score of 16080 with a processor speed of 1.2 Ghz while the processors actual speed is 1.5 Ghz.
even i did a factory reset and tried running the benchmarks.. but still the same results in 16k-17 window..
is any one else facing this issue after installing the update

Isn't it affected by the numbers if apps you have on your phone? And it's always better to do a restart and run the bench mark right after before running any other apps.
And btw, those numbers means nothing. Don't get hooked onto those apps, it doesn't mean your phone is any slower than others.

Yes, those are just numbers .. but still i was puzzled if it was happening after installing the update.... otherwise the phone is fine. except for the known heating problem :cyclops:

But the fact that Antutu is showing he has a 1.2 Ghz processor, for me is a reason to worry. Even if the numbers are lower, it should show 1.5Ghz.
So, maybe there is some overheating problem on his phone.

Antutu has recently been updated - refer the comments on the Play Store. Seems other people with different phones getting high scores before the update and then lower scores post update.
I think this is the solution to the problem...... Mind you I just ran Antutu and got 20656

When the XZ heats up, the processor throttles down. That's why it shows you the 1.2Ghz.

AnTuTu is kinda generalization of hardware accessibility and performance
So i think it almost depend on Kernel, after that update all kernels updated to Feb. kernel (a kernel with different date)
and Sony said will update xperia Z to 4.2.2 with 3.6 (*nix) kernel
and it can increase performance and higher AnTuTu benchmark
:good:

As far as I am concerned, I think these are all crap in reality. Because you can run these benchmarks over and over again and keep getting different results, even after disabling things like autosync etc.
In theory the phone should run benchmarks faster when it is colder, but when I ran these tests they were much worse.
My phone didn't change much after updates for bench mark scores.
Phones do have a thermo throttling of the CPU to stay within the SAFE temperature ranges, so the 1.2GHz will most likely have something to do with this.

Yes, indeed the benchmark programs depend on many factors.. i had factory restored the Rom from Sony Pc companion, and again the first time i run, it shows me 20k number.. and then it gradually decreases when i run again. i wonder if its the same with other phones which have the same processor.

Don't think so, every device I have used has done the same thing, find it impossible to believe that it is a problem device. The problem is most likely to do with the way that a phone operates, if the memory does a garbage collection event while you are doing a test, is going to throw a ridiculous result

Choppy/Framerate Issue When Gaming?

Hello, everyone.
Thought I'd take this question to XDA, since I'm unsure if I have a defective unit or not.
I have a HTC One (obviously) and it's stock, unrooted 4.1.2, running the latest 1.29 update. But when playing some games, I've noticed that ever 2 or 3 seconds, I'd get some sort of...frame jump, or random choppyness when playing. It's not framerate lag as far as I can tell, and when running benchmark tests, they appear to be fine.
The games I have tried where I can see this issue are:
-Mini Motor Racing
-Ski Safari
-Temple Run 2
I don't game that often, but these are the games I mainly play when I do. I know that not all CPUs/GPUs are made equally, so some people may not have this issue, but some *hopefully* might.
But as I say, when I run an AnTuTu benchmark and watch the GPU benchmarks, I see no jitter or jumping.
I'm wondering if I have a defective GPU or not, and just wanted to see if people are in the same situation as me.

It could be that 4.1.2 doesn't have optimized GPU drivers for the Snapdragon S4 processor. 4.2.2 runs games like butter, but I think the GPU got a speedbump on that OS. I know you said your on stock, but try applying a custom kernel like from Faux, and see if it makes a difference, maybe OC the GPU a bit.

It's not about drivers, it's about heat throttling. HTC somehow decided that when the CPU hits 40 degrees everything should slow down to keep below that target. Which is bonkers considering many countries have ambient temps of 30+, and the speed of the monster in the One. With custom kernels you can adjust this setting and to delay the throttling.

Thing is, when the phone is cold and below temps and I start a game, it's still pretty jumpy. So I don't think it's that.

Custom Kernel OC, Developers!

Hi guys,
OUYA need some good developers or really good one developer. Where are the times when I had HTC Wildfire and with this phone was everything possible a lot of developers. OUYA kernel looks quiet bad. 720p doesn't work and gamming at 1080p isn't smooth. So we need overclock GPU (600MHz+) or make working switch to 720p. If you think you have had 720p already, check this at CPU-Z or Nenamark 2.
Goddamn my MK802+ with ****ty overheating Allwinner A10 is switchable to 1080p and 720p!
If is anybody here what can improve kernel or resolution please do it. I think we the OUYA users can donate good developers.

I'm still at it, but very little time to get into custom kernels

Good to hear that. Could you make working switch to 720p and 1080p. I think this is what everybody want, could make OUYA powerful. Or disable the 520MHz limit for GPU clock. Please, I will buy you some beers

why don't you use forced resolution mod in Mod Collection for Xposed Framework? should do at least the resolution part.
and for CPU/GPU:
I know for sure that tegra3 is build to be able to operate at higher temps and should be safe until ~75-80 degrees celcius.
With that in mind and the fact that we have active cooling i think oc should be possible, but would it be useful?
Stock CPU speed is maxed at 4 cores @1700Mhz, GPU is set to max 520 Mhz.
In theory it sould be possible to get a safe max for gpu at about 650Mhz, but you would notice the difference only a bit. Pumping it up to lets say 700-750 (technically possible but might become unstable) will bring just heat, noise of the fan and almost no noticable difference.
I started the kernel and did try some tweaks to get better IO-speeds and also tried to implent gpu-oc, but back then this kernel renderd my ouya useless and i had to order a second one. Since then and given the fact that this year had a couple of bad suprises for me and my family i still got lot of other stuff to deal with, whenever i got time and feeling like i want to, i get back to kernel development and try to a) unbrick my first ouya and b) read, learn and test some stuff. (i'm ne to all of this as well)
to this point i have nothing i would want to share, since it doenst give any pracital improvements to existing kernel
as soon as i have something that is worth sharing, i will do so

With this Mod app you can't get 720p your TV say that but if you run benchmark you will see 1080p a score like 1080p even your TV say 720p. Only way is use Tegra Overclock Ouya, you will get 720p but not fullscreen. In becnhmark you will see 720p and much better result than with 720p in this mod app.
Possible max for this GPU should be about 650MHz as you sad, I think it will give you few more fps at 1080p even more at 720p. But max cpu clock is 1.6Ghz for all cores only for first it is 1.7GHz. Check it with CPU-Z.

So first goal should be 1,7 on all cores. Shouldn't be to hard to accomplish.

Adreno 3xx GPU Driver for Android 4.4.4 KitKat - flashable package

Greetings,
This driver is obtained from Qualcomm's 07 Aug 14 drivers for "Qualcomm Adreno 3xx GPU on Nexus 4, 5 & 7 devices running Google Android 4.4.4 KitKat".
All credits go to the folks at Qualcomm for making the developer version of these lib files available for us to play with.
This is for testing purposes only. Please don't flash without backing up first and then start screaming if something happens to your phone!
The package only contains files for Adreno 300 and 330. I cooked the packaged to be flashable on our SM-G900T or any SM-G900 with the Adreno 330 chipset.
I'm on a "XtreStoLite_G900T_ROM_v1.3_UVU1BNG3" ROM, which is a super clean/slim version of the stock rom. This is also Android 4.4.2, my AnTuTu benchmark results dropped from 37400 to 35800 after flashing this package.
I'm requesting someone with a KitKat 4.4.4 ROM to test this and report back their before and after benchmarks.
I appreciate your feedback,

Hmm, interesting.. I'm only on 4.4.2 or I would help out..

Turned out the 3D performance on antutu version 5 with this driver puts our phone one head and shoulder above everyone else!

And this means....... I'm sorry but I don't understand the purpose... Is this supposed to make Tw snappier?
Thanks in advance!

It is updating the video (graphics) drivers. It probably improves the touchWiz performance as well (don't have evidence to support this), but what i noticed was a huge performace increase in the 3D graphics score. This will make games run alot smooter and more efficiently.
To clarify, this file resembles how your Mac/PC has a video card with say NViDIA or ATi video cards and they have their own driver releases. Our phones graphic chipset is designed by Qualcomm and it gets its own drivers as well. Hope I answered your question, and didn't make it worse!

In order to get any real "TouchWiz/Nova/Apex/etc" performance increase from it you'd have to flash this, then venture into Developer's Options and enable Force GPU rendering and Disable Hardware Overlays. And even then our device is so performance driven that you likely would likely not even realize the difference other than giving the CPU a break for a few cycles and possibly seeing a battery life increase depending on whether the CPU or GPU pulls more juice. These drivers are largely made to increase the 3D performance of your device when gaming and while it wasn't meant for us I'm glad to see someone took the time to let us benefit from it.
I'm going to flash it on an NG4 (4.4.2) release and see how it holds up to GPU rendering no hardware overlays. I don't game so if you want an objective test on that someone will have to pick up my slack. I'll report back when I know if it truly impacts it.

Tried flashing the update and ran into a couple random fcs for a few apps. Nothing device-breaking or anything, but I also didn't notice any real difference in performance or framerate in games. But I do appreciate you posting this, I'm always up for trying a little experimentation on my device to find something new. Thanks man.

Don't worry, I didn't forget about you. It takes a few days to really put it through its paces. But here is what you want to know: It works in 4.4.2 Touchwiz (Alliance Rom B4 for me)
Performance Increase in ROM function and control with "Turn Off Hardware Overlays" and Force GPU Rendering: Check
So I tested this by underclocking my CPU to the point where lag was perceivable in things likes app launching, keyboard typing, app draw opening, etc. I dropped it down to about 1200Mhz on all cores and then disabled HW Overlays. It was night and day. After the GPU took over rendering my CPU clock speed hardly moved all of the items previously lagging went right back to being fluid.
So does it help with Rendering in the ROMs? Yes, it definitely can.
The other concern people have is with battery life that goes with GPU rendering and the claims are that the GPU uses more power than the GPU. In my preliminary testing, what I noticed was lower overall CPU temps while Hardware Overlays was off, lower CPU clock speeds since it didn't need to render apps, and a small decrease in battery life.
In the power draw category I need more time with BetterBatteryStats and I need to adjust some variables. I want to underclock the GPU to the point of perceivable lag (if that is possible) and then I want to adjust the governor with KTweaker and see if I can't get better battery life. I will simultaneously lower CPU speeds to keep my core temperatures down and keep the battery cool. If these things are successful and battery life is interchangeable between the two, I may run the GPU full time for rendering the ROM. Keep in mind though, only custom kernels allow this kind of tweaking. If you use a stock ROM you are stuck with CPU and GPU clock speeds where they are so battery will drain faster.
Give me about a week to test my theory on this and see if I can find an equilibrium for CPU and GPU temperature and speed. I'll post the profile I used with KTweaker when I have my results. Until then, if you want to help and find your own settings and post them here along with battery life that would be awesome.
Edit: For what it is worth, to test application launch speeds and UI fluidity with the GPU I completely turned off system animations, I set Nova Launcher Animations Speed to Faster than light and scroll speed to "Fast" (personal preference). I got the same, or better response time using the GPU to render the UI.

Performance Increase in ROM function and control with "Turn Off Hardware Overlays" and Force GPU Rendering: Check
So I tested this by underclocking my CPU to the point where lag was perceivable in things likes app launching, keyboard typing, app draw opening, etc. I dropped it down to about 1200Mhz on all cores and then disabled HW Overlays. It was night and day. After the GPU took over rendering my CPU clock speed hardly moved all of the items previously lagging went right back to being fluid.
So does it help with Rendering in the ROMs? Yes, it definitely can.
The other concern people have is with battery life that goes with GPU rendering and the claims are that the GPU uses more power than the GPU. In my preliminary testing, what I noticed was lower overall CPU temps while Hardware Overlays was off, lower CPU clock speeds since it didn't need to render apps, and a small decrease in battery life.
In the power draw category I need more time with BetterBatteryStats and I need to adjust some variables. I want to underclock the GPU to the point of perceivable lag (if that is possible) and then I want to adjust the governor with KTweaker and see if I can't get better battery life. I will simultaneously lower CPU speeds to keep my core temperatures down and keep the battery cool. If these things are successful and battery life is interchangeable between the two, I may run the GPU full time for rendering the ROM. Keep in mind though, only custom kernels allow this kind of tweaking. If you use a stock ROM you are stuck with CPU and GPU clock speeds where they are so battery will drain faster.
Give me about a week to test my theory on this and see if I can find an equilibrium for CPU and GPU temperature and speed. I'll post the profile I used with KTweaker when I have my results. Until then, if you want to help and find your own settings and post them here along with battery life that would be awesome.
Edit: For what it is worth, to test application launch speeds and UI fluidity with the GPU I completely turned off system animations, I set Nova Launcher Animations Speed to Faster than light and scroll speed to "Fast" (personal preference). I got the same, or better response time using the GPU to render the UI.

Thanks for the detailed response, can I flash this over a cm rom or only "touch wiz" and/or after I updated/flash this no Mauer what rom I flash will it stay. ..?
Thanks in advance! I'm still a bit confused...

I haven't tried it on CM yet, I'm about to flash the 09/04 build of CM11 by Albinoman with KT's kernel. But I won't flash these drivers prior to running the build 24 hours or so to make sure there aren't bugs that existed before flashing the files. So, if you've been running CM for awhile and want to test this build just nandroid, flash, and report any issues.

Ooo that sounds like a killer combo cm + kt kernel + adreno update = project slip n slide lol nah but I'm really curious of what results you might get [emoji4]
And once I flash this, can I go back or will it erase the update once I flash a different rom?
Thanks in advance!!

I'll keep you posted. I wasn't impressed overall with it's performance in Touchwiz on battery life with the CPU underclocked, so I am branching out to a more AOSP-like build. I'll keep you posted to what I find out.

Turned out the 3D performance on antutu version 5 with this driver puts our phone one head and shoulder above everyone else!

This can't be right because right now I haven't flashed the driver update and look at My score
Now imagine that's without kt kernel just stock kernel, I'm on xtralite 3.5a t-mobile, so what if I flashed the kt kernel AAAAND the adreno update.... would my phone explode?!?!
I'm thinking twice now whether I should flash thisor not. ..

You have a good point. I think antutu v5 also rescaled their scoring system. Anyway, post your new score if you decided you want to give it a shot.

This maybe off topic, but does this works on other devices like Z2 or HTC M8 using the same GPU?

43718 before
43292 after
All I did was reboot into recovery, flash the ZIP and then run the test, same clock speed etc..

Lower score, what about gaming?

You guys make me sad. Benchmarks are not now, nor will they ever be, an acceptable means for telling you how capable your device is. Your scores in AnTuTu are about as capable of telling you your phone's speed as your ESN is at telling people who your phone belongs to. It is just arbitrary numbers that will fluctuate up and down based on the slightest inconsistencies.
Drivers, just like in Windows/Linux/Mac, are meant to optimize the performance of your hardware. That's it. This driver likely optimizes the GPU cycles to make it more efficient and lower heat output while performing better in games. You know why hardware review sites start out with benchmarks saying what it can do in a perfect world but still ends the review by telling you it gets 75 FPS in Borderlands 2? They do that because while synthetic tests are nice, what would be the point if our games don't play better? It is the same concept here.
I'm begging you, uninstall AnTuTu, re-install your favorite mobile game and just base performance off of whether it plays better or not.
Side Note: Drivers didn't appear to do anything in AOSP CM11 when I gave it a try. Sorry I am so late on reporting in, college takes up a lot of my time. Also, using the GPU to draw your applications does eat more battery whether you use these drivers or not. So there is no marked improvement from lowering CPU speed and using GPU only to render.

I figured since the OP stated he got less points in Antutu, I would go ahead and use the same app and test to compare...
F*ck me right?
Regardless, I don't notice anything different either, my stats are in the sig.
