As long as you can have means to cool it! Im not saying its ok but it will decrease the lifespan of your device substancially, especially if you just leave it jacked up all the way
You may switch CPU governor to performance. Not necessary means it will use max. freq. all the time, use will give smooth performance for games.

As I understand solution for "998 MHz with screen on" bug is found: http://forum.xda-developers.com/showthread.php?t=1225411&page=17#post16944722
We need to replace only one governor.
I don't want to play with different ROMs and kernels and I'm looking for simplest solution.
Is it possible to compile it as a module ("ondemand_mod" for ex.) and add it to stock ROM?
Or any other (simple) way?
Wrong section ...

Exactly, this is the right section for such request.
However, I can't help but wonder: is this really a "problem"?
No offence to anyone, but I find that the phone is very snappy
when on max frequency... The big problem for me, would be if it
didn't go into Deep Sleep immediately after turning the screen off
and stayed at min frequency for an extended period.
When the screen is on (aka using the phone) I'd like it to be as FAST
as possible. That's the reason I use the minmax governor.
Anyway, again, I don't mean to argue with anyone, I am just
presenting my point of view.

Yes, it's really problem.
Higher frequency - higher power consumption. Moreover - with higher frequency CPU used with higher voltage so consumption is even more higher. So at 998 MHz CPU eats about 5 times more battery than on 246MHz.
With properly tuned governor I don't feel any real lags or slowdowns.
And, when screen is on CPU load is usually is lower than 20% at full frequency. So I don't want to waste my battery.
As I see it's possible to compile and use governor as module.
Could someone compile it? And assemble as xRecovery package?
Or point me where to read about compiling for arm, where to get tools and so on...

The thing is, on 245 MHz, you can't get any kind of decent performance.
Try this: set the minimum and maximum CPU frequency with SetCPU to 245 and attempt to use the phone normally.
Also, you might be right about voltage, but if the CPU is forced to work on lower freqs when it actually needs higher, there's definitely stress and increased battery consumption.
My phone lasts for more than 24 hours and it's always at max frequency when the screen is on. No lag, no freezes, no drain.
I do agree that the ondemand governor might not function as expected but I fail to experience the actual problem. That might be just me though.

There is no need to work on 245MHz as proper governor rise frequency automatically when it's necessary.
And really no stress for CPU to work an low frequency at full load. Moreover - CPU will consume more power at 500Mhz with 45% load than at 250Mhz with 95% load.
Sometime I use phone for navigation - long time with screen on and very low load. In this scenario battery drains very fast.
And last one - I like to have everything working properly. In case that I'll really need high frequency all the time I'll use other governor. I just want to have a choice.
I need a simple solotion for this too..I use z kernel and I found that Thego2s kernel fixed this problem..I was going to flash that kernel but think that has a bug and stoucks on logo ..can some one sayas a simple way?
Yes, I think a lot of people would prefer to use just small and simple fixes rather than replacing the whole kernel with a lot of nice but (personally) unnecessary features.
I am waiting for developers to release a fix for this problam
I've never OC'd any of my phones before but was keen to try it on the Galaxy Europa as the 600MHz CPU seems a bit weedy at times. What settings would people recommend? Ideally I would like good on-demand performance, good battery life and no frying of the CPU
Thanks
I not guaranted for the results but you can try to raise to 710. I tryeid and its work for me on any of cyanogen roms.
I use smartassV2 with a frequencies range of 122-480 Mhz. For me a longer battery life it's more important than waiting a second! And if I need to play something hard I set max to an upper freq..
my 2 cent..
Just wondering if its bad to set the CPU to run at 1500 MHz all the time on the Xperia S? I am using CPU Master to set it to performance profile.
I don't think it's potentially harmful for your device.
However, it will consume much more of its battery, resulting in decreased battery life.
Possibly it will also generate more heat.
Besides, it is completely unnecessary to do so. Your phone will manage the speed depending on the required resources.
Hope this helps.

its complettley unneedet, and using just a lot of battery. performance is ust realy needet for Benchmarktests, all other things can managet via ondemand or conservative
i want to disable both big core for best battery life. so my question is if i disable both big core then any chances for hardware failure? or something wrong with hardware?
Thanks

no problem i am using only the smaller cores but keep the maximum frequency to the highest and minimum frequency to the lowest and set interactive governer.

ur r welcome.if u r using radon kernel set highest frequency to 1478 and lowest as 400.

currently on stock kernel
so better to keep the big core on.but set the frequency low
why not use the hotplug option like in radon kernel?
In past experience, turning off the two big cores does not do much in increasing battery life. Besides, it will decrease performance of the device and put a larger load on the little cores.

thanks for sharing your experience. can you describe what is the use of hotplug?
hotplug turns off certain cores in your cpu when there is no need for the extra processing power, like when you are doing light tasks. It will turn on those cores temporarily so you get more power when doing intensive tasks.

oh it is really good option for save battry
There's something odd with Snapdragon 625 on RN4 (according to me).
I have noticed that the maximum clock is half of the times coming down to 1.6GHz or less instead of 2.0GHz, especially when charging when the phone is warm (but temperature isn't high enough to trigger down clocking-- around 30-40 degree Celsius).
This also happens when the phone is not charging and I am doing some task like using apps or playing games when the phone's hardly heating up (afterall, SD 625 is known for its no heating issues).
It looks like whenever I am doing some task that doesn't involve much processing, the max clock comes down (but when I am performing some CPU intensive task such as installing an app, the max clock stays at 2GHz).
I am using interactive governor. PLEASE NOTE THAT I AM TALKING ABOUT THE MAXIMUM CPU CLOCK WHICH IS AFFECTED IN MY CASE. Using Kernel Adiutor to reset max freq. to 2GHz hardly works. It seems like the system ignores my clock settings. Even if i set the governor to performance, the max clock still keeps coming down and going up.
What's the deal with this processor?
Also, all the 8 cores are ALWAYS ON. There's no option for CPU hotplug in Kernel Adiutor.
Please someone shed some light over this.
CPU is thermal throttling not only when CPU is hot, but also when battery is hot. Also it is using a frequency which it needs, if it's using 1.6ghz it means it doesnt need more for whatever you have been doing.

It also happens when the phone is not warm/hot.
Please note that I'm not talking about the current frequency that is being used, I AM TALKING ABOUT THE MAX FREQ that is pulled down and up when I am working (even when just simply using the phone for little tasks which doesn't really heat the phone up).
While using any governor, the max freq should stick to what it is set to and the current freq varies. But here, the max freq is varying along with the current freq. Is this some feature or what?
If this is actually due to heating, is the management so bad that even 35-40 degree celsius makes the CPU throttle? Generally throttling happens at much higher temperatures.
This is 14nm SoC, it has much lower temperatures but also much lower max temp. (throttling start on lower temps)
You can't heat up this CPU to 60C or more like Snapdragon 8xx for example, because it will shut down.

LOL means I can't make good use of the 2GHz 8 core CPU for long because it'll heat up and simply throttle down. That's too stupid to have a powerful processor.
i am having heating issue. I found no thread discussing.. I am in Miui9 global beta version. Rooted withMagisk using redwolf twrp. My top part of screen heats in normal usage for 5 minute in wifi/data.I have checked the cpu temp( maximum 42) and battery tem( 36 to 38)..But the screen become hot..any work around? Is it a software or hardware issue? how to resolve it
