GPU OC - Galaxy Note 3 Q&A, Help & Troubleshooting

Can we actually oc the gpu on the note 3 ? I have latest AEL Kernel v7.12 and I've put the frequency in the /sys/ folder to 550,600,500 and none work , also I tried with Fauxclock but doesn't work . Yes , in CPU-z it says adreno [email protected] but I launch asphalt 8 or other games and put cpu-z on-screen and the gpu never hits more than 478 mhz , I have laziness on 10 and ramp on 1 . Thank you !
EDIT : I don't know how i managed to miss the "Don't post questions here " sticky but I'm sorry!

Yes, it's possible. It's kernel-dependent, but I have mine set to 487.5MHz, and I can verify that it does, in fact ramp up beyond it's stock limit.
That being said, the limit it's set to is a maximum, so 99% of the time it will be operating well below that. I also believe that it depends on how the app is coded.
I've never seen a kernel with limits as high as you're trying to set them (that's not to say they don't exist though). Maybe try scaling it back a bit? Stock is 320Mhz, so pushing it to 600, if it's even capable of such, seems like it would be incredibly unstable and possibly damaging to the GPU...

CPU Govenor question/idea

Hey guys, ive been testing out the different governors. This is kinda android wide.. but ive only got my trusty HD2 to test on. If an administrator thinks this thread belongs in the Android General, feel free to move it.
So my idea/thoughts:
Ive noticed EVERY govenor doesnt really "scale" the CPU. Once it hits 100% it seems to shoot straight up to the MAX CPU SETTING.. This is redunant, as when one is web browsing, text messaging, calling, file browsing etc etc.. one does not need max CPU settings. All its doing is wasting battery. I can have an extremely smooth phone at 614400 set as max. Except when i play any high res games. So i created a script which sets my max CPU back to 1.6Ghz. I've placed said script on the home screen and i just tap it to run it then launch my game. I tap another script after to set max back to 614400.
So i am wondering if anyone can make a governor that is more "scaling" then immediatly setting the CPU to MAX when the cpu hits 100%. Maybe add some sort of timer, like if the cpu is at max for x amount of time then jump up. Or some other option to allow the CPU to stay at a set lower level. Ive tried all governors and Ondemand with a decent power save bias works. But it biases at frequencies of 96mhz or whatever your min value is. So we should be able to have a power save bias to bias at a set frequency.
My other idea was writting an apk that would see what the foreground app is and then throttle CPU according to user settings. Like say if angry birds is open, it would throttle to 1.6Ghz or whatever MAX cpu setting you have. Then when the app is closed, it would throttle back down. Its pretty much my script but lazified. ;P
Any and all thoughts are welcome this is just a brainstorming thread
Is this a bad idea? Or not possible? Nobody commented

Seeing which? Making an apk that see's which program is open and throttles accordingly? I would rather have a governor that throttles better. Just dont know how to achieve that. Ive gotten my smartassV2 setting pretty tweaked. Its mostly been in the lower frequencies but lags at a couple of things when texting. Maybe i'll finally cave and learn full fledged java programming and make an apk...

MTK devices overclock possible MT6582 successfully overclocked !

Hi guys I'm new on xda and I'm really sorry if I post this thread in the wrong place.
I found a method last year with I think we can overclock/underclock our MTK devices.No custom kernel or ROM is required but the problem is that the CPU can't be overclocked.Only the GPU and other components like RAM and internal memory.
All you need to do is to install a MTK Engineering app from Google play store.
After that go to /hardware testing/DE-sense/PLLs - you will get to a menu with some different PLLs
ARM PLL - is CPU ( but can't be overclocked )
MM PLL - is the GPU ( it's safe to OC )
I don't know about other PLLs , I don't think is safe to OC them and you will not get any boost in performance.
There are the default PLLs values for my MT6582 device ( all clock speeds are in khz )
ARM PLL=1092000
MM PLL=500500 max / 266000 min
MSDC PLL=416000
MAIN PLL=1092000
VENC PLL=295750
UNIVI PLL=1248000
The best OC values for GPU are 315 MHz minimum frequency and 518 MHz maximum frequency,the minimum possible underclock frequency is 245 MHz minimum and 450 MHz maximum
From my tests I got a 10-15 fps boost in PSP emulators and 5-10 fps boost in 3D games (real racing 3,asphalt 8,modern combat 4) and benchmarks (antutu 5,gfx bench)
Here are the default clock frequencys for MT6589
ARM PLL=1508000 max / 754000 min
MAIN PLL=884000 max / 500000 min
MM PLL=338000 max / 286000 min
UNIV PLL=624000
MSDC PLL=208000
Here is the YouTube link,check it if you haven't understand this tutorial : https://m.youtube.com/watch?v=wY_i3u_Wu4w
Anyway I need an expert opinion to tell me what the other components are.
Attention !
- overclock can harm your hardware
- please make sure that you can remove your phone's battery because if you put a wrong value your screen can get stuck ! But if you are lucky your device will reboot
- make sure your device is rooted and you know your default clock speeds
- Do not try to OC any other components,only GPU is safe to OC
- I'm not responsible for any damage to your phone
I can't post this thread elsewhere because I'm not allowed even if I have more than 10 posts,admins please if you find this useful move it to a good location
very interesting. i want to try this on my unite3 lollipop with SoC 6582. but before that i want to ascertain default values for MMPL which i could not find when opened in engineeing mode. will you pls reply how to find default values.

Edit: whether values stick even aftet reboot and how to check it has overclocked or else.
Sorry for so late response but I don't have a mediatek phone anymore. Anyway so no you can't see what are the defualt values in mmpl but you have to find out your gpu clock speeds ( the maximum freq like 600 mhz and the minimum one,which the gpu idles at like 120 or 200 mhz). If you say that you have a mt6582 phone your maximum freq should be 500 MHz and you could try a 533 MHz overclock. Only big problem at this gpu trick is that we can't change the voltage also,so an stable oc will be very small. I reccomend to oc that idle freq which I don't know why this mali 400 uses it even in games making them lag. So try to oc that 200 MHz to 300 MHz,but don't go higher because the kernel will think that you want to change the max 500 MHz freq so the performance will get worse. First set something like 303000 and after 515000.These are some ideal valuse which I've tested by myself. Sorry for my bad english and greetings from Romania.
how about mt6750?
Wont work on my nokia 3 TA-1032
Sorry, this is a late reply but i dont know why it says "Fail to enter De-Sense PLLs module" when i tap PLLs.
There is no de sense pill option in mtkengineering mode on my device mt6761 android 8.1

Is there any way to overclock the gpu for Galaxy Tab 4 7.0 (sm-t230nu)

I found a thread here xda about how to overclock the cpu Galaxy Tab 4 7.0 (sm-t23nu). In that thread the creator of that custom kernel had a problem increasing the frequency of the cpu when it came to 1.4 Ghz (version 2.2 kernel) because it appear more laggy. He then later made other version of that custom kernel that was down clocked to 1.3 ghz. So I actually tried the older version it was fast but what I noticed was that cpu was going really fast(everything open up quicker apps processes were getting done more quickly) but the gpu it self was bottleneck the cpu. I noticed that because when game with it that and everything was going smooth and fast but the rendering of the image was struggling to catch up. So I install aida64 on my tablet to see how much Mhz the gpu going at 416 Mhz stock speed but what I really found interesting was that it's not even going at it's maximum stock speed which 533 mhz so it can literally overclock to 533 Mhz and still have headroom for a 5-10% overclock which could be about 650 Mhz. So I was wondering if there's any way to overclock the gpu for this particular tablet. Thank you in advance
Hey
I too create custom kernels for this specific tab and let me tell ya it's a big pain...u can overclock the gpu but it requires changing alot. You have to change the plls the gpu runs on and on top of that it breaks the frequencies the cpu runs on and also the gpu info doesn't show up at all so if u plan on building pull the repository for the tab 3 which uses the same chipset. Then go to the files that are related to to the gpu which all I did was delte the gpu folder and replace it with the tab 3's galore file which will allow u to see the gpu info in kernel aduitor etc etc. Also one more thing I have a kernel with it overclock to what I believe is 1.6ghz.. and the gpu is capale at overclock ed frequency of 832 mhz
Good luck!!!

But that's problem I don't know how plls (what are even plls?) of the gpu? Plus I tried searching out on xda and other sites on how to edit kernel on overclocking frequency on both cpu and gpu but there's barely information how to do so and the only thing I know is that every kernel has different ways of changing frequency within different kernels so it's not the same for usually most of the time. XDA only shows how to add scheduler and cpu frequency also it's very general idea but in the gpu side there's no information about it. Can you give me advice what program I should for editing kernels clock frequency of cpu and gpu? Also where can I learn to edit the kernel for the galaxy tab 4 7.0?

my tab 4 7.0 is 1183 mhz, and yours is half of it? whaaat??
??? 1183 MHz ??!! How did you manage that ?? Mine is at max 533 MHz .... , checking the forum like crazy how to increase the GPU MHz range . Like OP mentioned , CPU already @ 1.4 GHz instead of the default 1.2 GHz quad core speed . But seems that the GPU can't catch up : result rendering images on high end games are slow ( hangs , laggy ) .

Yeah because the cpu is doing everything fast while gpu is like snail due to the low frequency and graphical api (OpenGL 2.0) it has which can not be fixed for api but tweaking the gpu to higher frequency could help alot in cpu overclocking. It would be better if it had OpenGL ES 3.0.

I can't really tell if you are joking or not because you're a senior member and should know this but what i'm talking is GPU-Graphic Proccesing Unit and you are talking about is CPU- Central Proccesing Unit. That's stock frequency of the cpu for that tablet mines also used to be 1183 Mhz in cpu frequency and now I overclock 1.344 Ghz. The problem is when I try to go to 1.4 Ghz the cpu is very fast at proccesing information I can literally have 10 or more tabs in google and multi task and it super fast compare to stock speeds but when I see video or game on it lags because there's a bottleneck with the gpu.

Over Clocking Kernel

Is anyone working on a kernel to overclock our amazing phone's CPU?
Umm are you trolling?

The way the clock frequencies are done on this phone, the kernel has no control to overclock.
I asked the developer of ElementalX and also checked to see if thermal-engine existed.
No dice. No overclock.
Only GPU overclocking
So there in no known method of overclocking either Snap 845 or 855 CPUs, right? (i mean throgh software/kernel)
I've never seen the point of overclocking especially with latest chipsets

Is not possible, the CPU frequency tables are stored inside something called "TrustZone", basically the bootloader, and no one outside of Qualcomm has the ability and the tools to control or make changes in that area of the processor.

Even rooted? ...how very interesting... 0_0
This means not only that we can not overclock (and this must also mean voltage table is ..off the table), but also we can not "set" a certain min/max frequency, right? Let's say i want to have a min/max of 2.8 ghz, it can't be done through kernel

Actually you can. It requires a Kernel that supports Overclocking. As of now there is no Kernel for the 6T that supports CPU Overclocking. Smurf has GPU OC but not CPU. Besides, the 845 is already a beast so I dunno why would you want to OC
I think me and more features will be driven by the chipsets themselves and will use a Trust Zone not accessible from the kernel (like widevine).
What is sure is that many CPU clock parameters are not accessible, that's why only GPU OC is present. This have been discussed in different kernel threads.
And the real question is why OC on those fast CPU, just to empty faster the battery and warm the phone in winter?

Isn't related to root or unroot, It's a limitation set at a lower level, lower than the operating system or the kernel.
You can modify the ramdisk to set the Max/Min frequencies, but those values ​​must be within the stock values ​​of the processor, I mean, you can't create a new frequency, you should use one that already exists.

Oh, so min/max can be adjusted? That's something at least. Sometimes the CPU assesses wrongly the speed needed to properly run an app (a very CPU heavy one) so restricting the CPU to lower the frequency provides the best performence possible on that hardware.
And yes even a powerful Soc like 845 and even 855 are pushed to the limits by certain apps.

It's not the apps fault, the scheduler is a bit broken in 4.9 thanks to CAF.

Yes and no, OOS applies boosts from the userspace, I mean that although you limit the frequency of the processor, in certain circumstances that limit can "break" (I don't use custom roms on this device, so I don't know about it, but probably the same thing happens).
This is interesting. I want to look. Into tz and see what I can find

Not exactly.
This chart is for the sd865.
Mi11 has a sd888, so the voltage levels will be different.
The basic idea is the same. But it requires testing and proofing.
Do you have source of konabess app? If possibility, send me pls :3
Thanks really useful
Great guide, this post definitely deserves more views. Got one question: if my goal frequency is (let's say) 660MHz, isn't it better to set ddr7 and ddr8 max values to 11? Would it squeeze out more performance at max load, in your opinion?

Not really. The ddr timings are not really set for balanced performance.
Trottling happens alot, so finding a balance give overall better performance than burst performance thatxthen gives lower results due tocthe time to cool being longer than the time to heat up.
I was able to get a higher antutu score than stock at 670, with timings between 4-9
But its all based on user preference and work loads. These settings work excellently well for me.
The big difference though is the voltage table. Less electricity going in creates less heat.
The ram timings are just a minor tweak to add a bit more to the clock. Its the voltage that really changed big time for me. Lower volts, less heat, longer time at high clocks.

Hi Patrick, sorry to ask but you abandoned for some reason?
I have a OnePlus 9R (SNAP 870) and it's hot, I'm looking for an undervolt on it but I can't find anything, could you give me some direction?
Use this table from this post in this video.
Max freq on Poco F3 is 683Mhz you have to try if can be overclock higher but Undervolt is still possible as all phones.
I recommend new version 0.15 on two lower freq retention and min_svs or low svs on third and do like in this table so 670 voltage SVS_L2.
I don't think that Snapdragon 870 is good choice for gaming better is to buy 865 and overclock to 950Mhz or 1ghz giving snapdragon 888 performance with lower temps than 870 and 888.
If you do root try to underclock CPU to 865+ 3ghz or 2.9ghz to lower temps performance difference isn't noticable.

things just update faster than I have time to test.
my charts became old, even the one Dr.Brown is using on his video, its quite old missing voltage steps and have not been tested on the newer versions of Konabess.
my original thread here took about 3 months of my time testing every possible setting to make sure other users didnt brick or toast their devices.
I took everything down when I seen alot of new rom updates, and konabess updates were causing bugs in the settings I had here for many users.
I didn't have time to retest everything and update my charts, I also had to deal with people stealing my charts and claiming the work for them selves. which I had to open youtube reports, contact google with proof of my work contact admins here and a few other sites too, etc all because some people didn't want to add a credit of where they found my charts.
so after a good week of emailing and chatting on the phone with google fraud control i decided to not continue posting my work, that may actually cause damage if used wrongly was too much work to deal with.
I'm still just too busy. my phone is stock android non rooted now because some apps I use can't be hidden.
so, I have no time to update this thread. I have no desire to leave the information for others to brick their devices.
the chart on dr.browns video is older than my most up to date chart, but still even that is months behind the current app and rom version changes.
my best advice is, if your phone works the way you want it, dont mess with any of the clock speeds. just undervolt some steps that are commonly used and test those.
too many people have tried to overclock their phones GPUs above 900 and lost functionality (permanently) or just hard bricked the phone (where an unbrick tool wont recover it.)
many will say its harmless, but its about usage. if you game alot and want to game alot, overclocking will create more heat, even if you undervolt. the result will be a paperweight.
those many people are not you, and not your phone. so anything can happen.
be mindful and careful of the settings you use. and install a temperature monitor for CPU and GPU.
going over 70'c will risk the loss of your unit.

Perfect understood Patrick, it's a shame all this happened, unfortunately people don't give value/recognition to people who help for free!
I'll enjoy and tell you my experience, my 9R is on OOS 11.2.6.6 (Stock) and with Kernel Stock as well (since there isn't much customization yet)
They ended up recommending the Dr. Brown video and I decided to do some tests, if the person copies the Overclock that he does in that video (905MHz) the device will not start, it will be necessary to flash the previous boot.img
This happened to me and I was able to reverse the situation (probably because the KERNEL does not support such clocks that would even be unnecessary)
But on his channel there is a more recent video teaching how to Underclock and so I took the clock's as a base and started to make my fine adjustments
Clocks follow this pattern; 512 - 490 - 455 - 445 - 305 - 295 - 195
Voltages as per your chart; SVS_L2 - SVS_L1 _ SVS_L0 - SVS_L0 - LOW_SVS - LOW_SVS - LOW_SVS
And the BUS frequencies I left original, so I found SWEET SPOT, the device is much cooler, stable, in games despite the Underclock holding well (80 FPS+ with graphics at maximum)
Hopefully there will soon be some app/kernel that can undervolt the CPU too, maybe just remove -25mv/-50mv and do some testing as most of the heat comes from it.
I'm quite satisfied and I'm grateful to you because without your charts in Dr. Brown's video, wouldn't know how to do!
I wish you all the best, success!

Perfect understood Patrick, it's a shame all this happened, unfortunately people don't give value/recognition to people who help for free!
I'll enjoy and tell you my experience, my 9R is on OOS 11.2.6.6 (Stock) and with Kernel Stock as well (since there isn't much customization yet)
They ended up recommending the Dr. Brown video and I decided to do some tests, if the person copies the Overclock that he does in that video (905MHz) the device will not start, it will be necessary to flash the previous boot.img
This happened to me and I was able to reverse the situation (probably because the KERNEL does not support such clocks that would even be unnecessary)

I recommend Overclocking by your self to higher freq.
This config from video don't boot on any sn865 devices even Apollo but I can overclock to 940 MHz stable.
I know that Poco F3 has lock freq to 683 MHz after that doesn't boot.
I think your UV is too high 512 can get as low as SVS_L1 or SVS_L0

Unfortunately on the OnePlus 9R (all stock) any clock higher than the original (670 MHz) the system doesn't boot (I don't know why, maybe some ROM limitation or KERNEL doesn't support it)
I ended up Underclocking to have a cooler device and in fact it is cooler without loss of performance in normal use and holding up well in games at maximum graphics
No artifacts, crashing or instability
As for the voltage on 512, it could really go with SVS_L1 - it goes between SVS_L2 and L1 on Patrick's Chart (525 - 512 - 490 MHz) I intend to do a test soon, for now it's stable and in games it doesn't get too hot!

No it is lock by Qualcomm to that freq so of doesn't boot it like 855+/860.
That why I buy Mi 10T with 865 and can be overclock to even 2ghz by someone.

Understood, a custom KERNEL doesn't unlock this lock by Qualcomm?
I had a OnePlus 8 with 865, today I just miss it

Maybe can by i case of 855+ was lock on all phones from manufacturer process.
But early builds of F3 has unlock freq but after that they are block that why buying 865 is better if you want performance for gaming or emulation like switch. I now play Zelda breath of the wild on my Mi 10 t and after 168days will be Overclocking to 940Mhz giving me performance of 888.
