A Few Questions about UnderClcoking and OverClocking - Xperia Play Q&A, Help & Troubleshooting

Hello people !
First a Fall , I am a member since a long time here , but never used to interact as i had jumped off the android bandwagon . Now i am back with a band with my new purchase of a really Awesome Samsung S3 :fingers-crossed:
i need Some help from you guys for a project i am writing .
I am writing on how under-clocking and over clocking an android SmartPhone would affect its hardware & software. mainly Focusing on How would the changed affect its performance , Stability and Battery life . And finally arriving at an optimum clock speed and if possible and algorithm to finding that optimum clock speed if its there .

I had an xperia play which i as using a long time back . its working perfectly fine . I decided to use it as i know the risks of over-clocking and how it may be dangerous to use on my primary phone atm .
All i am asking you guys is how can i go about this ? what all do i need to do to change the clock speed of my play ?
what apps can help me measure the battery life , stability and perfomance cahnges ?
basically please help me in anyway you can !
i will credit everyone in my study who helps :victory:

To over clock or vice versa, you need to have a custom kernel that allows it. A custom ROM is also good, but not always needed, but it is suggested Some apps on the market have over clocking abilities but an over clocking kernel is needed that is compatible. Also those apps have a kernel, but is specific to some devices. But go to your device's forums and find a kernel that has over clocking abilities then flash it. Some apps just allow you to over clock to the SET speeds of the kernel being used. Also for battery life, I suggest you use betterbattery stats on the market.

SO which config would be the best ?
hey Thanks for your help bro !
considering i am already in the forums for my device , can someone recommend the best kernel and the best rom to install ?
And how do i go about installing it ?
PLease keep in mind it should be able to support maximum over clocking and underclocking .
Thanks !

Underclocking is doable with just root access, which can be obtained by using ZergRush. This will only work on firmware 4.0.2.A.0.58 or lower.
For overclocking, I would recommend DooMKerneL which requires an unlocked bootloader. It supports frequencies of 134MHz to 2GHz, though I think the stock kernel can go down to 122MHz or 128MHz or something (DooM changed the frequency table in his kernel).
To test the stability of your phone after overclocking, you can run stress tests with StabilityTest. Underclocking will not change the stability of the phone, it'll just make it slower.
My favorite ROM is Gin2JB, although anything stock-gingerbread-based should work just as well.
For testing performance, I recommend AnTuTu

Thanks again
Thanks for your help !
Now one question , does doomkernel have inbuilt over clocking and under clocking ?
also as you said it resitricts the underclocking to 134 Mhz but the stock goes to 122 Mhz . isnt thier a way to make this one also go the lowest possible value?
and what about the Adreno 205 @ 245 MHz GPU that the play has .. can we overclock underclock that somehow ?
Thanks again

Yes overclocking capability is built into DooMKerneL, and of course underclocking. You'd have to talk to DooM about putting in lower frequencies if you want anything lower than 134MHz in his kernel. He tried overclocking the GPU at one point, but it oddly gave worse performance in a blind-test so he removed it.

While we're one the subject of over clocking, you NEED an app like SetCPU to overclock right? Just wanna make sure DooMkernel isn't already set to 2.ghz. Yeah probably a noob question...

Yes, you need an overclocking app. I think it defaults to Min:249Mhz Max:1017MHz. The Min might be lower, dunno. The Max definitely is 1017MHz (1GHZ) until you specifically tell it to overclock though

I would like it if theres a kernel that ALSO allows to underclock and overclock teh GPU AND CPU .
Otherwise i take it , Doom is the best to go forward with right ?

[Q] Want to overclock stock via kernel or run a stock rom with an OC. Help please.

Basically I have the stock 3.70 rooted and all types of stuff. What I want to do is use a kernel that has the overclock set to a frequency 100% of the time. I dont want to use an overclock app.
If possible, are there any stock(based) roms that are overclocked out of the box, without the need for an overclock app? Ideally I would like to flash a kernel on the stock that I have now and have that kernel run the clock speeds at the overclock speed, for example 1.2ghz(example), 100% of the time with no throttling or governor.
thank you in advance for your input.
umm.. ..excuse my ignorance but why in the hell would you want to do that?
So your saying when you and your phone went to sleep you want to be max oc'd....
This is easily done with setcpu profiles and I don't think its a good idea just on battery life alone let alone stress from constant oc
swyped from my cm7 w/4G
Thisss , would kill the phone. No doubt at all. Even no over clock running at type clock 100% of the time would kill the phone..

Brother this is 3rd time i am replying you in this topic..
I have already suggest you too keep min 352 and Max 710 in setcpu which is very much stable for me...
If your phone is not supporting the overclocking more than 691 than you can flash a new kernel (may help).
You can use InfinityPlay from here
Make sure to take a nandroid...
and one thing whatever you do it will be sole responsibility of yours so read before doing anything..
I think the above explanations will help you...
Press Thanks if I helped you...

I have given you a link for InfinityPlay Kernel...to flash HCDR kernel You have to flash it via recovery 2.5.X.X
I suggest you to buy another phone. Stop waiting for magic from buzz lol.

I use scaling on demand 480-710 and it works fine : )
i run games fine on 652MHz, any higher and my launcher becomes jumpy and the system is just loose and unstable. Plus I see massive decrements in battery life at higher clock speeds.
Really u dont want to clock ur buzz higher than 700MHz - the battery and CPU will get too hot as there arent any cooling capabilities in a phone. If u want to game seriously buy a phone with a better processor if u want higher speeds than that.

[q] htc wildfire s overclock

I have htc wildfire s ...i hav rooted ...i want to overclock it 806 mhz.....pls tell me the procedure to overclock..
I am using htc wildfire rom ..pls help
First you need a kernel that supports overclocking.
If you using a stock Rom then look for the kernel that matches your Android version eg. 2.3.3 or 2.3.5 you will find them in the development section posted by Jikantaru
If you install a custom Rom then it will most likely have an overclockable kernel baked in.
To change clock settings I recommend 'no frills CPU' search it in the market or you could use set CPU.
Once you install one of the above apps then change the min and max sliders to the desired frequency.
if we over clock it much does it effect the speed or hardware of the phone?
Your phone may hang.
There is SetCPU for XDA members:

You will definitely get better performance and it shouldn't cause you any problems.
Use no frills CPU I find its better than set CPU, when restarting your phone set CPU doesn't keep your overclock settings even though its set on boot.
As for the govonor settings I would choose smartass2 and noop for the scheduler.
I would keep the minimum frequency on 245MHz it can go lower but it could cause some issues (lag and slow unlocking and waking)
Note: not all cpu's are capable of running at the same speed, I'm lucky mine can run at 806MHz but some people have issues.
If you notice any problems like freezing etc, then drop the speed to a lower frequency until you find the sweet spot for your CPU.
I had mine at 806 MHz with no problems

Should be fine mate.
But remember if in the very unlikely event something does go wrong I wont be held responsible.
youll have to need an overclock kernel for that. (and a rom which supports one)
go for dust kernel or cake kernel! These two are well known for high end kernels!

[Q] From 1024mHz to 2016 ???

I recently flashed "myONEv rc1.1" ony my One V..
All smooth, really nice rom
Although while using Rom toolbox and going to cpu sliders, under "performance"
i noticed the core could now reach 2016mHz when before flashing could only go at 1024 ...
I dont really mind with 2016, it isnt even the current clocking, just the max the phone says it can reach, and battery life seems to be the same as before.
Does this tweak come with the new rom ??
Is it normal ?
That would be the work of Titanium Kernel allowing you to overclock.
I would overclock slowly and test over time. If you set it to 2k it'll probably freeze and stop booting/reset and do other quirky things. Slowly OC and find your point of stability if you're going to overclock at all.

Yes. The ROM includes the TITANIUM kernel
http://forum.xda-developers.com/showthread.php?t=1607976
But you should set it to a lower frequency if it is not stable at that speed
If it is - you are a lucky one
Regards

Well i handnt noticed its set @2016 two days after i flashed the new rom. and its been 24 hours since then. So its 2 days of no problem usage. It works fine with the "maximum" slider so high. Ofcourse the phone is not working at all times @2016..
Thank you for solving my question
as far as I know rc 1.1 doesn't not comes packed with titanium kernel
did u flash it afterwards?
dont just say thanks hit thanks if i helped

[Q] How To Fix Game Lag

Hey, i have this problem from the begining...
So i have android version 4.2.2.
I'm running phone on franco Kernel 3.0.85 with Paranoidandroid Rom 3.56, Also i use app to OC my phone to 1,6ghz.
So everything is okay expect gaming , example when i play temple run 2 and i set on the best quality it will not run smooth you can see lags ingame and i think this phone should run it easily.
I was reading forum but i didn't found any solution for my problem, i tried to find busfreq_static with following informations :
/sys/devices/system/cpu/cpu0/cpufreq/busfreq_static
but there's no busfreq_static file when i enter to cpufreq directory , i use File Explorer just to check am i able to find busfreq_static file but i can't.
Any solution , any help would be much appreciated.
Thanks

I already know you OC, but you overclock controlling voltages yourself, or rather you rely on SR to do it for you?

first, dont OC to 1.6!! the following may help you:
go to Settings and click on Developer Options and enable Force 4x MSAA. Multisample anti-aliasing (MSAA) is a technique used to improve image quality. Since the Gnex has a GPU capable of supporting MSAA. Keep in mind this will also cause your GPU to work harder and your device may get hotter and consume more power than normal. It’s also possible that all games may not support this.

I'ts not problem about OC , even if i set to 1,2ghz there are no changes , i just dont know what could be the problem , cuz the game runs smooth on other phone which is not good as this one , thats weird , im not controlling voltages , i didn't touch anything.

No , it didnt help. I already tried it before , but when i Force 4x MSAA it just makes game more lagy , maybe cuz of game , anyway i gave an example Temple Run 2 , but even other 3D games are laging , why shouldnt I OC to 1.6 , could brick phone or ?
It can blow up your cat. If it's the same with 1.2GHz... Why are you OC'ing? Go do some reading on voltage control and smartreflex on 4460.
Something tells me you're forgetting basics on how to OC on this device. If you don't supply enough voltage for all the cpu steps, device will stutter and lag, might even reboot.

Well i guess i need to put higher voltage when i am OC-ing , and how much voltage should i use for 1,2ghz , default ? Or incrase to higher voltage value ? Tell me something more about it , cuz im not well informed

first thing you need to do is disable SmartReflex® across the board, so that your user-defined voltages stick.
messing with voltages is very device-specific. increment voltage by small ammounts, stress-test and use the device for a while to make sure it's stable.
have you tried running those games while running Google's stock kernel?

I guess that stock kernel is : JOP40C kernel ? Am i right , i didnt try that kernel , you suggest me to flash this JOP40C kernel and to try if something will be fixed ?

Do you even know anything about ROMs and kernels?
When I said have you tested this on stock kernel, I meant, did you try this on stock ROM, but specified kernel because, it's like, common knowledge for someone who flashes ROMs, that custom ROMs devs often alter kernel (and ramdisk) to support features on their custom roms..
Have you for example tried reflashing PA, and just PA, nothing else? Does it lag then?
Have you for example tried fully reverting back to stock? (factory images)
Why is it that you just want your games not to lag, not even trying to gain a deeper understanding about what people are telling you.
Listen, this is the last time I'm saying this:
I told you to check your voltages, since you're OC'ing, and expecting SR to do the job for you.
Test by reflashing again PA, with no custom kernel.
Test by going back to stock, through fastboot/factory images.
Temple Run 2 on best quality lags in mine too.Probably it was designed for 1080p.Just keep the graphics a little lower, doesn't affect gameplay or quality
