[O3D] Overclock/Downclock guide/tutorial?
- can someone explane safe way to downclock(or overclock) GPU/CPU for O3D, I want to downclock to safe some battery life.
Thanks
SetCPU (search xda-developers for free download or market for paid updatable version) works for me, detected cpu speeds and allowed me to change them from 300 to 1008 Mhz, also there are a few options how the processor freq change when needed. For now you can only downclock until a new kernel arrives (not 100% sure what kernel is and if it really enables overclocking - just saying). I didn't try anything with setcpu but if you do please post your feedback
i have installed but i cant set the clock, with setvsel for defy i can define 3 speed for the principal status, in set cpu i see only the maximum rate (1008).
help me tks
Have you rooted your device, before you run setcpu?
what about downclocking, is it really giving extra life for battery?
I use Antutu CPU Master to downclock, it has a cool widget.

to what numbers you downclocking and how is battery life after downclocking?
Hello world,
I am wondering what program you guys use to overclock your tablet? Or what procedure? I am currently at ARHD rom with ICS test 21.3 kernel and am wondering what clocks do you guys use - suggest also some UV list would be great
thanx
make love,
miHah
apps to control cpu speed
use: set cpu (paid) or nstools (free)
Ok, what about schedulers? I installed setcpu and its on "sio" ondefault. Which one to use and when?
I don't like setcpu, or any app to oc for that matter. When I was on ARHD (and therefore had to use an app) I used No-frills CPU control, not too many bells and whistles and worked.
I highly recommend 'interactive' for a performance governor, it's easier on the battery life than performance and snappy.
Default scheduler with wifi off during sleep tweaks is fine.
I use 1.4 Clock at home and 1.2 out and about, but you can probably go higher if you want, 1.2/4 is plenty fine for me though. (I keep my RAM really free though, I feel that is more important. IMO)
Hello guys!
I would like to ask you for opinion what is best ROM for you. I recently rooted my I9505 and installed CM 12.1 but I want to check another viable ROMs, but there are SO many ones in android development section
Since I love to play many games on my phone, Im looking for a rom that is categorized in order by:
- Maximum performance and fps stability
- System stability (yes it is at second place )
- Battery usage (Im using greenify)
- Features
Im open to any suggestions. In few days these is some free time for testing ROMs
Optimized CM13 or AOSP 6 by JDC Team. In Stweaks app, select the extreme performance profile. Antutu scores over 35000 while other roms score around 32000.
Yet for gaming, I believe 5.1.1 is better, JDC Team made those as well.
^ what he/she said.
When it comes to performance, JDCTeam roms are best, due to the included alucard kernel.
Switch to the extreme performance profile and you're good to go. Note that not all settings take effect after applying the profile, so you may need to reboot.
You will also get good up time, because the kernel automaitically switches to a low power mode when the screen is off.
But when it is in use you will get about 2 hours SOT.
With extreme battery you may get around 4-5 hours SOT.
The stock cm kernel, that comes with pretty much every rom, is ok and all for everyday usage, but when it comes to performance it kinda sucks compared to custom kernels.
@GDReaper Paradoxically, on CM 12.1 with performance battery profile (in notifcation bar) I get AnTuTu score near 38k. However, when I tested JDCTeam optimized CM 12.1 and changed to performance battery mode in notification bar, I got at least 30k score (however I haven't modified kernel via STweaks yet). Maybe I should give it a try .
By the way, is Alucard custom kernel contains fast charging feature? I wanted to test it as well
That battery mode from CM only changes the CPU governor to Performance.
Alucard kernel changes many different settings depending on the kernel profile.
Also, the S4 does not have fast-charge built-in. Only the newer phones have that feature.
Then I don't know why standard CM rom gave me so high score.
However I will test again Optimized CM 12.1 and reply back tomorrow (making backup and so on)
Optimized CM13 by JDC Team is the best in my opinion.
I would go for stock based one like lollirom v8
best stability, no lag over time...
Thank you all for answers
Checked Optimized CM 12.1 and changing profile in STweaks to extreme performance really gives huge boost (over 38k score) as well as extreme battery cuts its performance when battery is more important (under 30k score).
The only cons is that changing between profiles takes about 20-30 seconds but it doesn't bother me so much
EDIT: I read that when you install Lollirom v8 you have to change modem to HPA1 to make WiFi work properly. Is that really needed?
Im not convinced to modify anything other than system. Is it possible to backup my modem easily so I can restore it if something goes wrong?
I will be doing the same as you!! Ive been using Golden Eye for quite some time now, but am ready for something new

You can use a custom kernel to avoid the WiFi issue.
I don't know if there is any way to backup the modem, but changing the modem isn't hard either.
Lollirom will not change your modem, only official stock roms can change your modem.
I'm not a Dev. but for a while i was chasing the unicorn. I wanted to find a setting on my xperia M2 that gives battery and performance.. My phone got really hot after 20-30 min of usage on stock settings. So I thought there must be different ways to this. I use a custom rom Z5 style, it has the standard kernel as far as I know.
I studied some writings about governors like: http://forum.xda-developers.com/xperia-m2/general/ref-xperia-m2-cpu-governors-hotplugging-t3454006 and the main reason why I started tweaking with Interactive governor is this very useful thread: http://forum.xda-developers.com/showthread.php?t=2769899
As U can see I only used what was already on here I just wanted to share my current settings as i find them fast enough for daily use and quite battery friendly..
In the second thread you have a really good explanation on interactive and i find it to be a very versatile governor. MP decision is off with these settings.
Anyhow back to my settings.. I use Kernel Aduitor (an older mod version) to change my settings, it works for me the best.
1. setting is above_hispeed_delay I changed it to: 10000 787200:35000 998400:45000
2. boost : leave it at 0
3. boostpulse_duration: change to 0
4. go_hispeed_load: 95
5. hispeed_freq: 787200
6. io_is_busy_ 0
7. min_sample_time: 30000
8. sampling_down_factor:1
9. sync_freq:300000
10. target loads: 80 384000:85 600000:90 787200:95 998400:99
11. timer_rate: 30000
12. timer_slack: 50000
13. up_threshold_any_cpu_freq: 0
14 up_threshold_any_cpu_load: 0
If U try it, change it and find something that works better with less battery please write back!
Edit
I did some changes to the numbers, its a bit smoother and SOT with my type of usage is around 6-8% drop per hour on my phone.
This is a battery oriented setup with MP decision off. My usage profile involves a lot of reading so it is not that cpu intensive. Results may be different for You!
NOTE!
If U would like to have more performance try the Hawktail profile suggested by AutumQueen92 lower in the tread is the link
Awesome work bro...
Best battery backup!!!

You're linking to an old site, the newer one is here. Also, I get better SOT and performance with Hawktail. Set your sampling_down_factor to 1 (stock Android setting, not sure why Sony made it 0) and sync_freq to 787200 (sets all cores to this frequency depending on CPU load)
Hi thx for the reply sadly there is no kernel with Hawktail for the M2 as far as I know.. for sampling_down_factor ill try.

???
Hawktail is the profile name, not governor. You just take all their values except the ones that needs our own CPU frequency like in the attachment.
Oh did not know sry. I will try those settings and compare.
Do you have MP decision on or off? I have it off. These hawktail settings shortened my SOT considerably today. Performance is crisp that is true, but better SOT? not for me.

MPdecisions is turned on, because there are no other hotplugs. When mpdecision is turned off, all 4 of your cores are constantly turned on and locked at 787mhz. If your SOT shortened try the GhostPepper profile or experiment with your own profiles. Some people do have different times on profiles because of usage patterns
That was the case yes. I leave hotplug off. Actually all four cores are on all the time but when idling on 300 MHZ it does not use much juice really. I read somewhere that switching cores on/off actually uses a lot of battery. With my usage pattern SOT is better with hotplug off..

I see, that sounds good. Then sync_freq should be set to to minimum frequency too, otherwise they lock up at higher freqs.
Can anyone provide with a "explain me like I'm five" post of what is this about? And if it is as good as it sounds?

Hi, its about the governor that runs your cpu. Interactive is very easy to customize: it can be fast or it can be battery friendly but slower. These settings are a good compromise for me but might not be fast enough for You. The Hawktail settings are really fast, similar in fact to 6.0 settings. Your phone should be rooted and with a kernel that has interactive. With a kernel aduitor type of apk You can easily try out different settings.
Considering the fact that every s810 phone out there has over heating issues apart from the one plus 2 because time was actually spent on that phone would it be possible to disable 2 or even 1 core(s) on the s810 to get rid of the heating issues or can that only be done by Sony. You must think i am stupid but hey oh i am just uncomfortable with all the heat i don't mind a bit of performance loss when i know my phone does not feel like its being barbecued.

I use this work from rytekk on mm and nougat it is flawless, you have control over cores annytime above 30% battery, if below then z5 takes over...
Oh... Stock roms tested ?

Thx for the reply but could you possibly elaborate further what do you mean because I have installed this before in the sense it would make it faster but not disable 2 cores or under preforming like just tell me what I have to do with this so I can underclock / disable 2 cores

I dont know the whole science about thos but i folowed the manual, pushed these file in correct folders and rebooted... I use kernel aduitor, app that alpows me to disable or enable cores as i choose ( except if phone is thermal throttling or battery below 30%) now i go to workf iy dou don't do it till evening i can at least telly you how i did it step by step...

Oh ok makes more sense so lemme get this straight copy the filez to system etc then reboot. Then go onto kernel auditor and turn off cores of my choice as it's enabled them?
Ok i have those files renamed and ready at my dropbox, just copy them in /system/etc
Make sure to backup original files...
https://www.dropbox.com/sh/ue4bbik61aair9u/AADLznjHZzmExXbiSnZ_iTkra?dl=0
Now reboot
And if you want total control rename thermal-engine.config to:
thermal-engine.configdisabled
Reboot
Now you have control over cores, again if battery above 30% or ifphone is not thermal throttling
It allso takes some knowing in kernel aduitor if you wish i can screenshot my settings
I allso sugest some good cpu governors tp make the mpst of it, you have some in androplus kernels for marshmallowi think, not sure for nougat, and you can allso add then manualy

yh thanks would be appreciated to see your settings but i copied the files from the post i will try yours now but the one from the post gave me no control over kernel auditor, however a friend told me it can be done via kernel and odex..? if you know this way please explain if not i will try the configdisabled thing and see if that works thanks again
Still getting a really hot phone
Sory to hear that, i guess it comes up to all factors than annyone can forsee... Best i could do with those files and with greenify was super cool phone almost no drainage, but when working ( if so choosen) it was a performer and yes... Scorched hot
If you wish to have good nougat rom flash xz2 rom from xnoob, leave /system/etc as is, change nothing i am amazed how cool it runs and how great it performs... Battery life best till now for me, But do a clean install,
An easy way to reduce heat is to adjust hotplugging thresholds for the big cores (you'll need root of course). You can do that easily through Kernel Adiutor in the CPU Hotplug settings. Lower the "minimum cpus big" and raise the "busy up threshold". If you really don't want your big cores on just set busy up threshold to 100 or something.
I personally have mine set to 0 minimum and 87 busy up threshold. You'll need to make an extra adjustment to get 0 minimum big cpus to stick, otherwise it will revert back to the default of 1. (note: I'm on the latest stock rom)
Also, setting your cpu governors to interactive and fine tuning the parameters will further reduce heat.
Thx for that I am using the xz2 Rom lol could you send me a pic of the kernel auditor settings?

Yh lol thanks but I have installed the xz2 Rom and yh it was quite good but I was trying to eliminate the heat whilst the good performance oh well but anyway I kinda need those files from the xz2 because mine our kinda messed up now it would be appreciated if you sent me them via Google drive mega mediafire etc so I can redownload those files and not the whole rom thx
