GPU overclock kernel for ICS

If the SGX540 in P1000 can be overclocked to 370MHz, the performance of it can be highly improved like in Overcome Kernel.
(Can be showed in Quadrant Standard Edition. When it is in 370 MHz, the fps in the graphic animation of DNA can be promoted to 60fps. And got no lagging in anything. The speed(smoothness is nearly reached S2 which is official 2.3.6)
But however, it doesn't seem that any ICS supporting kernel can set the clock of GPU.
I am sorry that my English is not good enough to represent my idea, but I hope you can get what I am talking about.
And the most reason I want it to be real is that the potential of P1000 is quite big and in fact it is quite good!
PS Antutu SetCPU app can set GPU clock in Overcome Kernel.

Dang, I never knew that our GPU can be overclocked ^^
since this tab is getting old, maybe its time to overclock the gpu also?
Personally I'm agree with this

Probs a little off topic, (also to bump this up a bit)
But the Gnex which uses the same GPU can be overclocked to 512Mhz (Stock is 300 something I think), improvement seems noticeable in apps and in nenamark, you go from 27-28ish FPS to 31-32.
It would really help the tab, it seems to show age now (which makes me lust over a 7.7......)

What I knew is the potential of SGX540 in GNexus and GT are different.
GT one is 200MHz and GNexus one is 374MHz.
In Overcome Kernel w/ GT, the clock of SGX540 can be set to 370~38X Mhz w/ no crush but when it is 400MHz , the machine is seemed to be lagged.
The benchmark in Overcome 4.1 plus Overcome Kernel 4.0 can be promoted over the GT 7.7 (of course the mark doesn't represent the real using experience but let's just look at the 3D mark)

Haha, yea I know they have different potentials Just that I thought I'd let you guys know how much better overclocking the GPU would be.
I think its worth it, there is little impact on battery life, but the improvements in apps and usage are noticeable.

I think the battery usage for extra cost of GPU is not as high as CPU.
It is being a great difference if we compared the overclocking for either CPU and GPU.
The consumption of GPU is low and it won't make the device hot as CPU overclocking.
And the temperature can keep around 35 to 36 degree Celsius under a room temperature 20 Degree Celsius.
The result screenshot I have posted is undergoing CPU overclocked (1.4GHz) plus GPU overclocked(370MHz) w/ overcome kernel and rom.

Success!!!

Hello, i have been trying to implement LiveOC into humberos's kernel and it is a success
LiveOC
This allows us to modify the bus speed which increase both the cpu and gpu clock at the same time using an app called NStools
i have only been using this for a day now and it seems to be working very well
please report back any bugs thank you,
BTW i will post the settings i have used in NStools and this kernel is for the latest MTD build
Link: http://www.4shared.com/file/216rF_WJ/boot.html?
My settings:
Governor: smartassV2
min CPU freq: 200MHz (240MHz after applying OC Value)
Max CPU freq: 1000MHz (1200MHz after applying OC Value)
OC target low: 200MHz
OC target high: 1000MHz
OC Value: 120%

I'll give that a try when I get home (or maybe a few days later). So which ICS rom did you try this on?
EDIT: In terms of quadrant (which I know can be a bit volatile... but a nice way/quick way to see differences), ICS gets a lower mem score :< 3d is slightly lower, 2d is about double (I suspect thats forcing 2d rendering). This is comparing the gtab score in quadrant, I haven't used GB on my tab for a longgg time...)

thanks for the information
as a newbie, i just thought another aokp by stimpz0r is identical
there is a strange point which is the fc of the camera while the shutter sound is closed, but it works while enabling the shutter sound
It is a great rom and thank you for your great work

benchmark lovers

while I realize that many people hate benchmarks the truth in my humble opinion as a windows hacker and android enthusiast is that benchmarks, run properly, can tell you a whole lot. there is some variances but usually that is from screen brightness settings, running at different core temps, background apps, widgets, and waving the accelerometer around like you just don't care lol. and you can say all you want to synthetic means nothing but the fact is even manufacturer's use benchmarks in their testing of new chips as well. just look at the current benchmarks from sd 600 vs sd 800 from qualcom. so I have decided to carefully benchmark every kernel myself to find what gives ME the best user expieriance. maybe it will help the dev's, maybe not. maybe it will help you, maybe you hate my dog and want to skin my cat.
a benchmark can tell you how well the kernel makes use of the hardware so for testing purposes I have used stock rom on all tests. I have set up my cold box for testing so that the cpu and gpu do not suffer and return quickly to normal and have set brightness at 50. testing is done stationary against the back of the cold box proped so that cool air flows over the systemboard. for testing purposes there is only the stock clock widget and micro cpu monitor and a few battery temp/sytem stats apps running. after each benchmark the tablet memory was swept. all benchmarks were run 3 times and the highest score given is used here unless there was a wild varient and then it was tracked down and all benches ran again. after contemplating it i ran some of these plugged up to the ac on my cold box and sometimes i forgot to plug it up. and some using debugging but i honestly doubt that had an effect. so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background
im also not really comparing custom kernels to one another but I do to stock kernel, every last one of them are great and offer a lot of features you cant get with stock. all offer performance above stock if the proper settings are used and the overclocks are not to extreme for the framework. they are all also still works in progress so I think they will improve with the developers attention as time goes by. i started with stock kernel and ran antutu, quadrant, velimo, 3d mark ice storm, 3d mark ice storm extreme, basemark x, gfxbench 2.7.0 t-rex hd onscreen, gfx 2.7 egypt hd onscreen
stock kernel
stock ran well and i liked it, but i hated having to long press wifi to toggle and short press takes you to settings, wtf google?
edit.... so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background

whatever flo 002 kernel
the kernel ran smooth and i liked it. i have the same complaints about it as i do stock. wtf google?
so on this kernel as you can see it functioned better than stock on every single benchmark. some were close but just a little better is...well...better.

jassy release 5 kernel
this kernel is set up to use an external kernel control app. it will not function worth a hill of beans without it in my testing. and even further than that it seems to not like trickster mod for me as it bench's higher with faux kernel control app paid version. real world expierance is good. fauxclock is set to 1.89 ghz CPU OC. cpu ondemand governor. snake charmer and mpdecision on. intelithermal at 60 and 80 respectfully. gpu at 487. gpu simple governor. fiops i/o at 512 read ahead. as you can see in cpu and gpu performance it face smashes stock kernel then kicks it while its down and makes it cry for momma. i dont know what the dude pasted into this kernel but i like it. jassy worked hard so we could have a full featured kernel that works well. release 6 = win, release 5 o yeah baby performance even ondemand. i could still kick this to performance governor lol

elementalx 0.7 kernel
settings with no external kernel control app.
1988 cpu overclock on each core. 487 gpu overclock. simple gpu governor. stock bus. stock voltage. no stw, dtw. the kernel ran well in real world performance. STW and DTW are awsome features by the way and i really like this kernel but didnt install them for testing purposes, one less potential irritation. as you can see it actually lost a bit from stock performance though in every benchmark except basemarkx and gfxbench 2.7 t rex. that tells me there is a problem with cpu performance in this kernel. also look at the cpu vs gpu in antutu vs stock kernel. so what i like this kernel and with lower clocks, dude it rocks. stw and dtw are wins.

elementalx 0.7
settings with no external control app.
1890 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus.stock voltage. no stw, no dtw. again the kernel ran well in real world performance but as you can see it took a serious hit in performance at this cpu clock setting. the gpu features continue to score high though

elementalx 0.7 kernel
settings with no external kernel control app.
1728 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus. stock voltage. no stw, dtw.
as usual really nice running and here the voltage values are more sane i guess. bested stock in every bench. i figure 1.9 ish before the poo poo hits the fan and performance benches go south rather than north. that seems about the same for the other kernels ive tested too. flar2 really has a winning kernel here with stw and dtw. highly recommend giving it a try

3flo v4 kernel
not testing this one yet as my boy doesn't even have the nexus 7 2013 but I tell ya, I got a good feeling about him. seems dedicated and excited.
Edit...he just got a mpdecision kernel booting and posting good scores but has a cores on touch problem for me. Very beta but it shows that even without a device you can build. Still got a good feeling about this one.

faux123 flo jb 4.3 001 kernel ulta
not coming. I can boot it and even run at highest settings but antutu ehh and im tired lol. maybe ill do it if the overclock structures are changed in some way but ehh not interested in this high on this chip.

faux123 flo jb 4.3 001 ES
settings. faux 123 kernel control paid version. 1.512 ghzcpu. mpdecision off. cpu governor ondemand. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400 and ondemand. fiops I/o 512 read ahead.
so here you can see again the same slight loss in gpu performance which lead to slightly lower scores than stock. cool kernel though and I do like intelli thermal so

faux123 flo jb 4.3 001 kernel mainline
settings in faux123 kernel control app paid version. 1.83 cpu OC. CPU Governor ondemand. intelliplug. mpdecision off. eco modeoff. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400. gpu governor ondemand. fiops I/o 512 read ahead.
so I found the kernel smooth in real world. I looked for my sweet spot and found it around 1.836-1.89 cpu. above that didn't really work out well for me. so in this great kernel the cpu benchmarks higher than stock but for one reason or other the gpu seems to bench lower than stock. all in all a great kernel and omg I love the idea of eco mode and I think with proper cpu governor and eco this kernel would rock some battery butt.

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

Let me tell you my setting, a balanced between perf and battery. (Play BIA3 no lags at all)
Cpu Gov : Smartmax
Max : 1.2ghz
Min : 533mhz
Schedule workqueues : enable
Cpu Hotplug : Alucard
Thermal : intellithermal
Gpu : msm-adreno-tz
Max : 400mhz
Min : 100mhz
Adreno idler : enable
I/o scheduler :
Internal : tripndroid 512kb
External : fiops 512kb
For Gamimg Mode i just OC the cpu to 1.5ghz or 1.7ghz with same cpu Governor (smartmax) and same cpu hotplug (alucard). If necessary i oc the gpu to 550mhz or 720mz too.
For battery save.
Cpu gov : yankactive
Max : 1ghz
Min : 533mhz
Cpu hotplug : alucard
(Note: Because you are running on MIUI rom, maybe you still facing lags when play a game like BIA3 or Asphalt8 coz, miui has too much customization that make lags when playing hardcore gaming.)
Now, im on RR5.7.0 working great with the setting above and no lags mostly in all hardcore game like Asphalt8, BIA3, MC 5, Galaxy On Fire 2 HD, Real Racing 3, Dead Effect 2, Gangstar Vegas, Sniper Fury, Assasin Crees Identity (Tested with A6000 PLUS with 2 GB of RAM)
Best Custom Kernel? You can stay on Phantom Kernel with the latest version, it is the best kernel till now.
Cheers :victory:

I just switched to RR5.7.0
I'll try your setting

You must flash wifi patch for that.. Then open Kernel Adiutor/inid.d/ execute " 01wlanon ".. Then your wifi will work.. But, you must do this on every reboot

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?

??? 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 ) .

I use vim.....also the clock fIles are located in. Drivers/clock/mmp/pxa988.c
AND the gpu files is located under. Drivers/marvell/graphics

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.

Dude, I'm almost finished with it but I need to know where's the file dvfs-pxa988.c on the Galaxy Tab 4 7.0 kernel like when I go to arch/arm/ mach-mmp there's no file called dvfs-pxa988.c. under that directory. Like do you know where could be?

there is no file by that name... our tab uses this file for its voltages...android_kernel_samsung_degaswifi/drivers/clk/mmp/dvfs-pxa1L88.c
