Hi!
I'm looking for a kernel that supports both CPU+GPU over/under-clocking.
And more importantly, I need a tool which also lets me create easily appliable profiles for both clocks.
ATM, I'm using franco.kernel R142, with his tool. It supports profiles, but only for CPU clocks.
Thanks!

Franco's kernel doesn't support GPU overclocking, but I can recommend four that do have GPU and CPU OC/UC.

BTW, which kernel have you had the most luck with?
Also, Trickster mod does not seem to have GPU clock speeds in profiles.

Last time I checked the GPU option is available in Franco's kernel updater app. It's in "Frequencies/Voltages"

Yes, I know it is. But...
Caveat emptor :
1. You can only underclock. No overclock.
2. You can't set GPU clocks as part of the Power Profiles.
Any suggestions?

I don't think it's a good idea to overclock the GPU. The adreno 320 GPU is quite efficient and delivers great performance in it's default settings.
May I ask why do you want to over clock it?

Hahaha... Only for novelty purposes, and the heck of it... I haven't noticed lag in anything actually.
In fact, I tried running MC4 and NFS MW at the CPU at 1.1 GHz, with 400 MHz GPU - no lag. 1.5 GHz is overkill, IMO.
Mainly I need underclock. Which franco supports. BUT, I simply need profiles.
I want to set up lower GPU clocks for lower CPU clocks, for just internet browsing and stuff.
And, vice versa for gaming. If not over-clock, just default GPU clock speeds for gaming.
Any ideas/apps?
High I see that the n4 with the snapdragons4 pro can oc to 1.944 ghz and the one s with the s4 dual ore should be able to do that too if I take the pll and voltages from some n4 source like faux right. Just asking if the pll values for the CPU steps will work since the only difference is 2 cores between the CPUs and the base clock of 1512mhz is the same
Hi, on the internet i saw that Snapdragon 615's max freq is 1.7 ghz. Can we somehow make a kernel that allows OC to 1.7

We can. Do you want to be the one who wrangles the code?
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?

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

There's a few.... graphics/galore 4x/hal.... shows most of the files I believe
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.

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?

Hey... You've mentioned max clock speed for big cluster as 1651Mhz how's that possible... Is it a 1.7 GHz version ? I got z00ud 1.5ghz ... Or is it a feature from poison kernel... Just a clarity before I go for a dive

Hey ,snapdragon 615 can go up to 1.7 ghz but on stock kernel it runs on 1.5ghz
stock kernel (stock rom): big cluster is locked down to 1.5ghz and when trying to play anything it goes down to 1.1ghz or 800mhz
poison kernel (any custom rom):big cluster goes to 1.7ghz (1651mhz) when playing it thermal throttles to 1.4or 1.3ghz
fire kernel (any custom rom): same as poison
||with thermal throttle tweak||
stock kernel (stock rom): not tested
poison kernel (any custom rom) : while playing games big cluster stayes at 1651mhz and Little cluster shuts down (or uses one core on 200 mhz) *using impulse/impulse for cpu governor*
fire kernel (any custom rom): not tested

I never tried poison kernel but ... I used firekernel and it has only up to 1.5ghz I'm surprised poison let's you go an extra mile...that is not specified in the features list..... Well... I'll try it out and let you know here.... But I doubt why op would not reveal overclock ... So probably our device SoC is different... I've seen z00t with 1.7 but it's model number is different .. maybe ze661 or something.. mine is zd551kl

i have tried fire karnel and i did get 1651 mhz i flashed this edition ||FireKernel-r2.4f - (modified by op for 615)|| *it is very good for psp emulator*
if you read fire or poison threads you can find people that experienced overclock ........mostly 600kl models

Hello.
Do those kernels works on other Snapdragon 615 phones?
I have a Vodafone Smart Ultra 6, with TWRP 3.2.3-0 and Lineage 14.1 (no more updates from that version til now), and it throttles a.f. even @ room temps (like 20~24 °C) while the CPU seems to go up to 67~72 °C while working @ 100%, throttling to 800 MHz, and not keeping the 1467 MHz full speed on the big cores.
Maybe this phone doesn't have a great heat dissipation design (the SOC seems interfaced with a thermal pad to a thin shielding, then to the internal frame with a weird interfacing, at the center an adhesive part and on the sides a weird texture. Also the internal frame seems in plastic, covered with some aluminium powder or something alike.
Anyway thanks for every answer or suggestion.
