I just put OmegaROM v42, 5.0.1 on my i9505 and I'm finding some games a bit laggy.
Running imperium 2.2 kernel.
There are lot of overclocking apps out there, just wondering which is the best/most stable of them.
I downloaded SetCPu but cannot seem to push the S4 past 1890mhz.
Can the GPU be OCed as well?
Firstly, the kernel needs to support overclocking.
Secondly, you can also do that from within the kernel tweak app (e.g Stweaks).
If it won't go past 1890 then it doesn't support overclocking.
The only 5.0.1 kernel that supports overclocking for touchwiz is Hulk-kernel as far as I know. Currently up to 2.1 GHz overclock.
It doesn't support GPU overclock yet. But from what I saw the dev might be planning to add that too in the next version probably.
Make sure you download the OC version.
Also, I don't know what games you are playing that seem laggy, but it may be caused by DVFS.

I was playing Relic Run and it seems to get laggier the more you play.
How to fix the DVFS issue?
DVFS or Dynamic Voltage Frequency Scaling is present only on touchwiz roms. I don't know if DVFS is rom related or kernel related, or if it is disabled by default on custom touchwiz roms. But there is an Xposed module to disable it. I don't know if there is any other way.

i'm on stock rooted and tryen many apps like setcpu but without success.
monitoring the cpu with PERFMON http://forum.xda-developers.com/showthread.php?t=1933284
only cpu0 seem to reduce frequency and not all other 3 cores... and for a small amount of time
after some seconds all 4 cores return at max freq.
anyone have success in underclocking and what app use?
or i need a custom kernel? and in case how about a stable one?
Overclocking is simple on any of the AOSP ROMs

UPDATE:
Tryed TRICKSTER MOD on my LG G Pad 8.3 V500 with strange results...
i'm on rooted stock and before have tryed all sorta of apps with no luck in UNDERclocking... only 1st core underclock and not the others 3.
Trickster mod are the only that partially work DISABLING MPDECISION.
with mpdecision ON only 1st core underclok.
with mpdecision OFF all core do underclok but core1-3 NOT GO TO SLEEP when not used!!!
also... i try to underclock GPU but all the way they return to full speed even with mpdecision OFF
tests done with PERFMON http://forum.xda-developers.com/show....php?t=1933284
please help i DO WANT TO UNDERCLOCK
Hello
Any progress?
You need to run a kernel that supports overclocking/underclocking for best results on stock roms. AOSP Roms tend to come with a custom kernel that has this functionality.
see my other thread:

We all know what I'm talking about.
Have a Galaxy Nope 3 (N9005), stock ROM, go, for example, in Settings -> Connections, and scroll up and down. Chance is, you will see it stutter.
After flashing a multitude of ROMs, AOSP and TW based, I find the stock one most stable, so right now I'm stock, rooted and Wanam-ed.
What exactly causes the legendary S-Lag which causes a device with a quad core 2.3 gHz processor to stutter, and can it be removed without rendering the ROM unstable?
A bad rom or kernel causes it. Tested it out on MultiX 1.5 with kk-Xplorer 1.6 kernel and I dont have it. Then again, i tweaked my kernel and rom to my liking, if you just mass install everything, you will get lag.
Zero lag here, xxuend3, stock kernel, some apps, games disable from startup with android tuner.
Note 3 rooted knox 0, bootloader locked, my last Samsuck crap. I want freedom.

Legendary S-Lag = TouchWiz.
On AOSP no ROMs lagged for me, and I tried practically all ROMs available. The worst case are RR's..
On TW based ROMs, a bad experience means a bad governor from your kernel, for your device. Meaning that your device has a specific governor it likes, and to adjust this use Trickster Mod Kernel Settings available on the Play Store. Also heat dispersion and the kernels ability to scale frequency under high amount of load may cause problems, as the higher heat (theoretically more load) hence stutter and graphical latency.
All clean, stock, custom ROMs play nice because they removed a lot of Samsung's default list of S-Apps, which does free up process load on the RAM and processor. As said before TouchWiz plays a big part in lag, however I'm not saying it's not good. The S5 ports all are great but that's because people actually spend the time recompiling broken/useless code from Samsung's source code. Alexndr is a good example - where he started from 0 to 100 recompiling literally all of Samsung's permissions.
This is why people like debloated ROMs.
I Need the Best gaming Lollipop Rom for I9505 with great performance and Battery life ?
That would be AOSP rom by the JDCTeam.
Make sure you set alucard kernel to the extreme performance or performance profile if you want better performance in gaming.

"great performance and Battery life ?" Performence or battery life! 5.1.1 CM with Alucard Kernel
if you get an alucard kernel in your rom then the raising the minimum clock speed to 810 khz on all four cores and the minimum for GPU speed to 200 khz it will help.
*gentle fair sleepers off
*arch power on
*CPU governors to ondemand or alucard with alucard hotplug
in developer option hardware overlays to off.
personally I think ktkernel was better with more options but you'd need to stick to AOSP 5.0 for that or lower
If he were to stick to older android versions (5.0 and lower) then he might aswell get KT kernel, which gives him the posibility of overclocking the CPU and GPU, something that is missing from the other kernels right now.
GPU overclocking isn't really stable, it actually takes away from the gaming experience.
How can increasing the GPU frequency, and therefor the performance, be bad?
If you overclock it too high of course it is unstable. But you should be able to take around 500 MHz easily.

I can't remember the steps you get in kt but I'm pretty sure the uppermost ones were next to unusable, 500 is only just above the standard speed.
the games are always going to have a fixed system requirement levels based on the hardware we have so there isn't that much to gain over optimisations for our roms I feel...
I always judge a rom based on how well it can play shadowgun deadzone. most untweakable kernel rom combos aren't so great fresh out of the box.
Well, I used KT kernel in the 5.0 days. I ran a gaming profile created by ktoonsez himself, which had GPU overclock, and ran stable all the way.
I usually judge a rom by how fast it opens the settings app. This presumes that the app was fully closed, otherwise it will just switch to it, wich is a lot faster than actually opening it. Also, animations are all off.
So, between the pressing of the icon and the actual opening of the app there will be a black screen (if animations are turned off). The longer you see that black screen, the slower the rom is.
So I installed Kernel Adiutor to tweak the I/O performance and was kinda curious about the governors and all. I noticed that all 4 cores stay on at ALL times. Is this normal behaviour? Why is there no hotplugging? could it be implemented in a custom kernel?
Coming from a Snapdragon 801 which had quad custom cores, it used to have hotplugging to save battery. Thanks for answering if anyone knows

My only guess here is probably the Developer haven't add support for the new'er Snapdragon chip/s?
Been using Kernel Auditor for awhile and I see sd820 reads as single cluster where should 2 (big-LITTLE) . Well just a thought
ok that makes sense, do you know of a kernel tweaker which is updated to work with the new snapdragons by any chance?
I found an app that works, for anybody who is interested, EX Kernel manager works great with the big.LITTLE cores on the s820, happy tweaking!
I'm currently trying out the Interactive governor tweaks posted around the forums
Got correct kernal for stock sammy rom, installed ok, tells me its there, the higher frequencies are all listed in the apps ive tried( paid and non paid|) i just cant set the kernal above the usual 2.4 speed
latest 2.5 version installed using TWRP 3.0.0.0

Really? How did you check that you couldn't increase CPU max frequency?
I am also on Boefla and can't reproduce your issue - OC works well (see my screenshots).
Nevertheles I don't recommend overclocking as it may cause more issues than benefits. Just checked it for you to prove that it works.
Ok thanks..I've installed a light ROM and left the kernel stock.thatll do me

How did you overclocked without becoming unstable? Everytime I overclock my phone it reboots itself when I try benchmark or playing games. Will you show your me cpu voltages?

How much you can OC or UV is related to your hardware which is unique to each phone (one can more where other not).
I only did OC for short time with Boefla kernel to prove the user who asked that it works and only for this purpose. During this time it worked well -> no reboots.
Just after I reverted back as I never do OC or UV for my daily usage (exactly due to potential unstability).
