After reading through the Thread for the Pre Release of FuguMod Ultra in the development section of this forum I thought I would post some info up for people who are wondering why it doesn't work with their phone, and just some general info on overclocking.
- First off, not all phones will be able to run at 1366MHz. Every CPU made has a range of freuqencies it will work at, and it is different for every single one. So some may be able to handle 1366MHz and above, others may max out at 900MHz. If you are getting black screens, freezes, or random behaviour, then your CPU doesn't like the frequency you have it at, try a lower frequency.
- Always keep an eye on the temp of the CPU when testing overclocking, if the CPU gets too hot, and fail safes don't work, there is a chance you could fry your CPU.
- With the FuguMod Ultra kernel, you must also be aware that gpu bus frequencies have been changed, so if your phone is not happy with that it will black screen. (as bus speeds are like cpu speeds, every different device can handle different clock speeds)
- plls values have been changed, and these may cause problems on your phone.
So if you want to have a go at overclocking your phone, back it up, and then give it a go. Select a frequency, and test with something pretty cpu intensive (3d game, multiple quadrant passes) and see if there are any bugs/overheating during a 15min time period. If you notice any problems/too much heat, try a lower frequency, and try again. And if for some reason your phone doesn't like the kernel, you can reflash with your previous kernel or a new ROM as you have already backed up your data.
If you have any other questions about overclocking, feel free to post here and I will try my best to answer them.

How can you check the CPU temperature? I thought it was only battery temperature.

The battery temp is a good representation of how hot the processor is getting as it is right next to the battery (only a thin sheet of metal seperating it) If the battery rises in temperature by a few degrees, then you can summize that the cpu is probably getting a few degrees hotter than that. I really wouldn't recommend letting the battery get above 55degrees (celcius) as this means the CPU may be getting up close to 65degrees (celcius) which is a very bad thing.
Good post.
Note that if you want to make some stress-tests, you have to put "PERFORMANCE" governor and set the max freq you want to test.

Yes, Very true!!
Must also say, Your kernels are pretty legendary! Waiting patiently for the offical release of your FuguMod Ultra

How have you got your phone set up? i.e. what ROM are you using etc.
I am using stock jpq with app2sd, swap, zipalign, ramhack and stuff. Setcpu is installed with default min/max freakquency, No profiles in use and undervolt a bit.
Ok,
This may be an issue caused by XXJPQ, as it is a new release there may be some sort of conflict. Have you tried asking if anyone else has this issue in this thread? http://forum.xda-developers.com/showthread.php?t=1132697
I haven't played around with JPQ yet so don't know what the bugs are yet.
Also, are you running a stock kernel? Have you confirmed that the phone has been rooted properly as well?
It's definitely a bug in Kernel. I tried three different roms and i wasn't able to check time in state in any of them (I am talking about fugumod ultra prerelease kernel here).
With previous versions of fugumad kernel everything is fine. So definatly a bug in kernel.

Ok cool, I'll report the bug to the developer so that he can have a look into it. Thanks for testing and proving to the kernel.
Little bit of info some might find helpful. After some recent testing, I have found that some people might experience a black screen freeze when phone is in standby for a while with 83MHz min setting and on demand governor. I am not sure of the exact reason for this, whether it is a bug, or that the processor just doesn't like going that low for extended periods of time. If you experience this type of error, just hard reset the phone then open setcpu after phone has loaded and change the "standby" profile minimum to at least the next step up on the slider. Personally I use 223 setting as it provides a smoother lock screen animation, and no significant difference in battery drain.

Hello,
I have a peculiar problem with my OnePlus Two
The faster A57 cores don't get activated, I have tried using Antutu, played Asphalt 8 And NFS NL for hours.
But the cores just won't get triggered
I'm using A1 CPU tool to monitor the same.
Even CPU Z wouldn't show me any activity on the other 4 cores while Antutu was running.
Any ideas? It's brand new can be returned

I just installed A1 CPU to verify your issue.
It shows cores 0,1,2,3,4 are used at 1344ghz for me as well.
When i check with synapse (i'm on AK kernel) it shows all cores are used.
I guess it's a limitation with A1 CPU tool. Try with other tool that supports such architecure.
I was sceptical on the same but, out of the box I remembered seeing 1777 MHz frequencies.
Thanks a lot
I shall try more tools and get back.
Though I think if you're on a different kernel and had the A1 CPU tool been correct it would be redundant, Because core allocation would be done on kernel level (in my knowledge).

I know that it was already discussed but maybe someone has found a solution.
The problem is that performance of device gradually decreases proportionally to the level of the battery.
For example:
- battery is 90%, Real Racing 3 runs perfectly,
- battery is 45%, some lags appear during gameplay
- battery is 10%, heavily FPS drop, almost impossible to play
Battery saver is turned off, device is cold in all tests.
If I would like to save my battery level - I will turn on battery saver manually,
but I WANT to have good game experience not depending on battery level
This is really crazy.
Tested on stock OOS 2.1.1, with stock kernel, with Boeffla an AK, tested on Exodus ROM - everywhere I can see this weird behaviour.
May be some system files must be edited to overcame this issue?

Hi Jemcik, hi Denhot!
I'm facing the same issues on my new device and it's definately not normal!
With a battery level of 19% I was not able to get the 4 A57 cores online, which results in lower system performance. Have you found a solution?
@Denhot!
Maybe we should rename the thread into: IS OPT PERFORMANCE REALLY DEPENDENT ON BATTERY STATUS AND IS IT A ROM FEATURE OR AN ISSUE!?
I think, one of the kernel devs should be able to answer this question.

It looks like some system configuration files with kernels activation policy have to be edited,
but I haven't found yet which files exactly.

I've never experienced such a function!
CPU power depending on battery voltage!? 62k with full battery, 49k with 20% battery both with same CPU temps!
Hopefully not a general problem on our side with the motherboard Voltage Regulator or something.
Have you been to a kernel thread and asked this question? If not, I will ask this in AK's kernel thread. Maybe he knows more about it!
The 4 high performance cores will only be activated when needed. What app are you using to check the core usage? Every now and then you should see 2 of the high performance cores sometimes coming to life every now and then, with the other 4 power efficent cores being more busy. Use CPU-Z to check.
Due to the way Oxygen OS's stock kernel works, only 2 of the high performance cores will ever be active, alternating between the 4 cores in an attempt to keep the phone cool and not throttle as often. If you want all 4 high performance cores to be active as well as overclocking it back to its original speeds, you'll need to flash a custom kernel.

Hi,
would like to share I don't have a similar experience, with NFS NL or Asphalt, phone was consistent with no lags even when it got unbearable to hold.
I as playing and simultaneously screen mirroring over to a TV.
Going from 65 to 25% over a long course.
I normally won't let my battery fall below 20%.
So the thing about Li-ion/pro is that as you go lower voltage decreases so to provide same power draw current increases.
Basically it would heat up faster.
That can be a reason combined with that their might be inbuilt measures to save battery like you said, nor as an engineer I would recommend you to stress your phone at those levels.
I can't explain the lag at 45%, didn't find it might try real racing 3 later to check.

This is consistent with what I've noticed. The time It didn't, a simple reboot helped solve it and it hasn't occurred since.
Also these tools can't monitor the other cores, if you're rooted why not try synapse as helkat suggested

Thanks man!
I know how the S810 should work!
But I thought the performance issues have only to do with the temps. But now it seems it have also to do with the battery level.
It would be good if someone tries to reproduce the following to verify it:
1. One run Antutu benchmark with fully charged battery and room cool temps.
To be sure the conditions are the same, shut the display off for one or two minutes, than start display again, kill all recent apps and run Antutu test and note the results.
2. Than wait or do something until your battery is down to 20%, shut the display off for the same time, kill recent apps and start Antutu test run again and compare the results.
I've also tried the same after a reboot, with always the same results.
With 100% I get scores between 60 and 66k and with lower capacity (20%) I get only 48 till 50k!
I am not interested about the benchmark results, but I need to know if this only occurs on my side.

So, guys!
I have tested it the last few weeks and it is a fact that the performance in benchmarks is dependent by the battery level.
We have tested it with 3 devices and it is always the same.
But thank God, it seems on the devices perfomance themselves (in apps/ui) this has no effect!
But each one can replicate this behavior very easy!

I have the same issue! When battery level goes lower than 20%, my A57 kernels become offline. I checked this with CPU-Z and PerfMon. And this is the same on stock or custom kernel. Now I am using Boeffla kernel. The most frustrating is that my UI suffer from this. I have lot of lags in simple apps, such as calculator or some messengers.
Same issue here, there are threads in one plus forums.
I think the threashold level is at 40 % ?? They made this to keep the battery up. You can also see faster battery drop till the 40-30% mark then it is harder to kill the battery.
I am also dissapointed in this, maybe we can search the kernel sources ? Or is there a daemon app that triggers this?
I received the phone with 20%-30% battery, started an antutu knowing how powerfull 810 chip is, then boom 45k same as the previos phone i had with 801 chipset...i was like what the fxck....runing antutu again with full battery - 66k.
well i have run benchmark in back ground with few game and apps .. and checked with cpuz max that i have notice was around 50-60% cpu load still 2 off those a57 cores were off using this device for 2-3 days it always turns off 2 cores for me rest 6 is working most of the time :/ Even in battery saver mode .. i am not sure if this is a cpuz issue as i have not rooted my device yet so cant say properly ..
Also i face some freq. benchmark issue like in benchmark it scores around single core - 690 multicore - 2.6K .. and if i restarts device it scores normal - 1.1K and 4.5K .. i have no idea whats wrong with this :/
20% Battery Mark
The drop in performance at 20% Battery is standard behavior of the Rom and Stock Kernel. The Big Cluster (A57) is completly shut down to save Battery. If you dont want this you have to use a custom Kernel which is able to switch this Battery saving strategy off. Boeffla Kernel for example can do that.
Read http://www.anandtech.com/show/9828/the-oneplus-2-review/2.
They "optimized" the soc.....
No they just turned off some cores so there is no heat problem.
So I think this is my first and latest oneplus.
they've hit the mark! What the hell, i think they must be sued for false marketing. Its just like buying a car with 400 hp and those hp are only there when i'm parked or listen to music, if i'm on the highway or on the ridge the car has 100 hp...wtf :|

Calm down lol it's actually good on their part. Shutting down A57 cores on low battery is a good thing because the A53 cores use much lesser battery. If you're out on a trip and have 10% battery, with the A57 cores this will probably drain off within an hour of intermittent usage. When only the A53 cores are active, the battery life will increase greatly.
Companies design phones for average users, not just gamers. If you don't want this feature, root your phone, flash boeffla's kernel and disable the BCL Battery Driver. It's as simple as that
i recently brought my j5 installed twrp then didin't like cm 12.1 then flash 6.0.1 then dicided to go back to my stock rom the problem that the phone overheats so much 40 ° for deep sleep and 50 for normal use
i mention that i installed linaro kernel when i first used twrp
any help ? anyone had that problem before ? :crying::crying::crying::crying:
Hello! I'm the current developer for Samsung Galaxy J5 and want to clarify some things to new users.
Samsung Galaxy J5 heat issues:
- Has a 5.0 inch Super-AMOLED screen, that is the main cause for exceeded battery draining and heat problems.
- Uses 4 cores for proccessing which is another cause of heat issue.
- When we use full brightness on screen, mobile data and gps together, the device reaches its most battery-draining state and its peak in heat production.
- Stock kernel uses performance governor for stock ROMs! That means that your CPU is always at 1.2 GHz.
- Interactive stock governor also uses the range from 800 MHz - 1.2 GHz, so heating issues also occur.
The solution:
- Stick with CyanogenMod 12.1. The development is always active. Even if you don't like it, you will see better performance than stock. AOSP is always the best way to go.
I will post the new updated ROMs soon. (I have updated SM-J500FN today! The other variants will come soon)
my phone runs in stock disabled everp bloatware only installed fb lite with the slightest use the phone goes to 50 very fast
i flashed ur kernel before and cm rom same issues even when i go in twrp the phone is always in 43 - 46 ° do u know what's mostl likely the cause ?
my phone feels like an oven and i tried flashing official firmware but it the same problem i can't find any solution or similar experience to anyone
I faced same problem. Please help me my phone is Samsung galaxy J500F.
i also got the same problem
my j5 is very chill on normal use(like using facebook or browsing in internet using wifi) but it overheats very intensely when using mobile data and it even goes up to 70 degrees
also in using j500h in stock mm with kraken kernel underclocked to 1ghz
First of all, proof: http://imgur.com/a/vfRc8
As you can see whichever genius refurbished it has done a number on the phone, both CPU and GPU are overclocked. The phone overheats to 90+ celcius when attempting to play games and shuts down. The problem is that with the phone wasn't rooted when I bought it and it was still overclocked for some reason, I don't understand how. I installed custom ROM and kernel (Nameless and H Vitamin) and the problem still exists.
Can you please help me out here? I'm kind of a noob on customizing kernels to change clocking speed and I don't think the phone will last long with these settings. PLEASE help.
It looks like H-vitamin kernel is not installed properly, it still runs on the previous, OCed one. Try flashing RamKernel or Emotion.
Can you please PM me the current kernel boot.img? You can get it by dd command or from recovery by backing up "boot" in TWRP.
The kernel is same one I'm using but your could be a newer version, would be very useful to me.
I wouldn't worry about heat, I'm running 3.07 GHz & 800MHz GPU /w disabled throttling, for using GearVR with PC. It gets so hot it hurts to touch, still no damage after 500+ hours on steamvr but the battery lost some capacity.

Open it and give it root access.
From this you can change whatever you want.

The default clock speen of cpu is (300 minimum)and (2649 maximum.)
Gpu clock speen should be minimum 200 and maximum 600
Thank you both very much, I installed RamKernel RC3 and I'll use trickstermod to further downclock the cpu because where I live is preeeetty hot and I worry about the phone. Olex you were right, for some reason H Vitamin wasn't installing properly, I'm uploading the boot backup as I write this and will PM it to you.
Btw even with the new kernel inside air conditioned room the idle temp is 40-45 Celcius. Is this normal?
Hi guys
I notice my note 4 overheating so bad after I flash a custom rom to it (Lineage 17)
I use hKtweak to check the cpu temp and it never stable at a reasonable temperature (for me, it is around 45 to 60)
The battery temperature is fine tho. Its stable at 40 degree and so but the cpu not fine the device not laging its super smooth even with these heat.
So anyone have any ideas or should I contact to the person who make this Lineage rom. Thanks
If you don't know Vietnamese, Cpu is cpu temp (of course :v) and Pin is the battery temp

after flashing a rom it's normal to have heat, the rom it's building the cache and has many things running
give it a day or two to settle
also
exynos 5433 is well known for its heating issues
so play less games or less time
use it as a phone more than a play station
where did you download the rom?

Well, thank you for helping me but I found the problem by myself.
I tried to reflash the ROM but no luck. Then I started to disassemble the phone, use some iPhone repair techniques likes replacing detachable module like charging board. And you know what, after I replace the charging module and replace it from my broken Note 4 SM-N910P, the temperature dropped from 60°c down to 45°c
I hope this will help someone in the future
