[Q] Remove CPU Speed Limit in Android 2.2 - General Questions and Answers

How to Remove the CPU Speed limit of 600Mhz on Android 2.2, When I use Andoird 2.3 on this Device [Commtiva Z51], I am able to Clock the CPU at ~800Mhz, I want to do this on Android 2.2, I have a rooted Device.

Maybe a CPU Tuner
I am sure you can find a free one on Google Play you should take a look.

What you are referring to is known as overclocking (oc)...in order to overclock, you need a custom kernel, since (mostly) the stock kernel doesnt support oc

[Fyi, Android 2.3 is better than 2.2 in a lot of ways...]

??? What are you trying to tell??
Typed using a small touchscreen

I already have No-frills CPU control from the play store and it works but not over 600Mhz and yes, it is Overclocking (OC), I am running a custom rom, Android 2.3 Roms are available but i am not using those as they drain the battery really fast (even without overclocking). It seams like it is a limitation with Android 2.2 as I have tried other Roms also and they too have the same problem.

No nothing like that...
Oc is kernel dependent...you can make an oc kernel for froyo also...
And if you oc, you will get faster battery drain, and maybe heat issues...

Overclocking
Currently I am using this Rom (Jellybean <link> slinkme.co.cc/jellybean <link> [Added like this as I cant add links now]) , As far as I know this supports overclocking. And also if this kernel does not support Overclocking, Can you give me a OC kernel for Android 2.2.1 (This Rom).

All devices are different, and so is their kernel/rom/etc....you cannot use stuff for my device on yours...
And jellybean is sypposed to be android 4.x/5...and not 2.2.1
Give me a screenshot of the stuff written in about phone...then maybe I can point you to the right direction...
Typed using a small touchscreen

Jellybean is my Rom name, it is Android 2.2.1, I want a Kernel that Supports OC, Do you have one ? Android Jellybean is 4.1.

i think you can use Set CPU. you can find its on google play or appstore.vn/a

the easiest way...ask your rom developer to make a kernel with OC support. you can't compile a kernel for your device and neither me since I don't even know what your device is.

You really should listen to these guys & ease up on the attitude. YOU'RE the one needing help and they really are trying.
What kind of PHONE do you have & ROM are you running? THAT determines the kernel.

Be carefull,
It can damage your device...

Kernels for CM7 03012011 Nightly

Hi,
I am a new rooted user and have been following all MT4G threads here at XDA pretty closely. Can anyone help me know which kernels I can flash on the 03012011 Nightly(cm_glacier_full-11.zip ). I haven't ever flashed a kernel and I don't know what it does and how it helps.
I'll appreciate any info that you can give me.

Well you can use dumfuq's SmartCMKernel or Faux's CM7RC v1.3 kernels. ATM you might want to go with dumfuq's as its the most stable CM7 kernel other than default. You can find it in development section, once downloaded to SDCard just go in to Recovery and wipe cache, davlik and then Install zip from SDCard> Choose from SDCard> Select it wherever you put it and then flash it as you normally flash rom's. Then reboot and let it run for few min and let it do its thing.

Thanks for your help. Getting this kernel now. I heard about setcpu and Quadrant. Do I need those and how/what are they used for? what kind of difference would this kernel give me?
SetCPU - name explains it but if you don't know its controls clock frequency, so you can over/under clock and even set profiles.
Quadrant - benchmark app its just to brag how high score you got nothing special, don't let it get to your head it means nothing as the synthetic benchmark no way translate in to real world performance its just pissing contest lol
Keep in mind in CM7 you have built in mCPU performance controller to to handle clock frequency which you can access via Setting> CM Setting> Performance> CPU Setting.

Thats up to you as only you know what you use so you can better utilize the resource. I mean if you don't use anything no reason to OC it to 1.8ghz lol that way you will kill battery.

What are the differences between dumfuq's and faux's? Is there an advantage to one over the other? I've always been using faux's the whole time.
I keep going back to just using the stock CM 7 kernel clocked at 1.5 honestly I think it gives the best overall performance (on my phone at least) and honestly I had issues running over anything past 1.7 with any kernel but again that could just be my phone. I had it oc'ed at 1.7 for a while and now I have it clocked at 1.5 and notice I have less FC (not that I had many at 1.7 but def more apps would choke from time to time) This phone is pretty fast bone dry stock with no oc'ing but it runs beautiful at 1.5. I dont really notice much performance difference from 1.5 to 1.7 but I do notice a battery difference

[Q] Overclocking

Im rooted my desire Z yesterday to the gingerbread sense 3.0/3D rom.
im very happy that i have done it and my battery experience is either improved.
but my experience of the reaction time, smooth animation ect. were kindly bad
this is why i want to overclock my processor, but the rom included the new kernel 2.6.35.10 to be exactly. this kernel is not yet overclockable and i wanna know why.
- why make different kernels need different methods of overclocking
- why can it by bad if you overclock it to high.
- can i just flash another kernel to overclock my new gingerbread sense 3.0 rom.

if you overclock the processor of your device you can smoke your DZ
but if you do it with careful it is not bad for your device.
the kernel that you have its a stock kernel (factory kernel) and its not customized for to be over/underclocked... you should flash another kernel for to change CPU speeds...
nornally you can overclock your desire z (good machine mate ) 1.300mhz-1500mhz i not recommend to do overclock upper than 1500-1700... i had read some threads that some people was smoked his device (all with the proccessor QUALCOMM SNAPDRAGON 1ghz)another think its the freeze problem when you overclock your processor too much.. be careful!
and one important thing.. also its important if you do underclock.... don´t put it under 245mhz more or less because maybe your device don´t has sufficient power to exit of stanby mode
i recommend that ALWAYS do overclock with SETCPU.apk that its available free for XDA MEMBERS its the most safety mode
sorry for my english

ok guys i dont know weather its me or not
but i had flashed some kernals the are 1.5ghz but my quadrant score wont go up than 3010 highest i got.
some people on youtube shows them more than 5000 so i was wonder what was i doing wrong
at the moment im running CM7 lates build 158
and i notice some kernals wont work with lates buil
what kernals can i flash to overclock my phone as fastest?
and how.
thanks in advance
Try the cm oc/uv 0.4.2 kernel by faux, install setcpu (free to members here, don't have link at the moment). Inside setcpu is where you adjust the kernel speeds. From what I've noticed, a custom kernel will be clocked around the normal kernel speed (stability reasons maybe) so even with custom kernels your not running as fast as you can.

i done the setcpu all the way to 1000 but it didnt seems to helped. i didnt go into profiles cause i dont know what im doing in there.
What kernel are you using? You have to use a custom kernel to overclock. Setcpu will detect the settings created by the person that made the kernel and allow higher settings. With the kernel I suggested you can go up to 1.55ghz

[A700] [KERNEL] iconiaN - OC-UV

First as always, I am not responsible for any damages caused by using any files I release.
ok, right down to the point of this post.
I built kernel with the help of faux123 with OC/UV & GPU OC and have been asked to release it, so here it is:
Downloads:
iconiaN Kernel for A700 Final version
Currently it only clocks to 1.5GHz (Used SetCPU) more work is still to be done
GPU is OC'd to 520MHz
I welcome feedback and suggestions :fingers-crossed:
Please do NOT package these kernels with a custom ROM, instead point your users to this thread
Massive thanks to faux123 for complying with GPL, as I borrowed the GPU OC & UV from his kernel sources.
GPL States I should provide full source, so here it is: on GitHub
Wow. That's definitely a must have! I hope this will change the experience and launches apps faster.
Aren't the CPU and the GPU put together in one socket?
Will this kernel be packaged in iconiaN 2.2 by any chance?
I wondered why you wrote that the GPU is clocked at 1.5 Ghz. That`s a little bit too high in comparison with the mali 400 and other mobile GPU. Now I looked at your github and I see 520 MHz. A really nice Overclock too. Maybe you have clocked the CPU to 1.5 GHz?
I will test the kernel in a few minutes. Big THX for this
I was tired.
Was thinking CPU lol.
Yes it is a 520MHz sorry
I've not done the cpu oc yet though.

Vorbeth,
I downloaded and installed this last night. It was stable, but seemed to lag a bit. I think the OC of the GPU helps less than an OC of the CPU. Running the modified kernel OC'd at 1.4 seems to have a greater impact than OC'ing the GPU... it really seems like 1.3 GHz is not fast enough to support the higher clock speed on the GPU...???
Obviously, getting the both ramped up would seem to be the best scenario.
Your work on all of this for the A700 is very much appreciated!

This kernel does have the 1.4GHz cpu speed.
I'm going to see if I can push it a bit more.
Aiming for 1.6GHz CPU & 600MHz GPU.
Sent from my EndeavorU using xda app-developers app
Yes Sir! If 600 GPU aren`t stable, I think we can life with 500 too, when the CPU runs fine at 1,6 Ghz.
I`ve tested Wild blood(gameloft game with the Unreal engine 3, that works after I edited the build.prob) with your default kernel, and I think it was around 20 fps so I definitively need more horse-power
Sorry for the Double post, but I have downloaded your new kernel from google docs, and I`ve got no error during the CWM installation. So nothing to worry about Sir

[REQ] KQM Kernel with OC @ 1,8 Ghz

Hey guys,
Since im a heavy gamer ( Modern Combat 2/3/4,N.O.V.A 3,NFSMW and some other games ) i decided to take my phone back to stock KQM with root. I previously was on CM10 but the gaming behavior of it is just awful. I didnt managed to play a online round of MC3 to the end. It crashed, or lost Wifi connection every single time.
KQM is way better for gaming. Its almost fluid all the time, but i didnt managed to get it complete fluid. Sometimes there are lags for 10 - 15 seconds, and you know what that means for a FPS Gamer, its horror! And you want to throw your phone against the wall when youre in a 14 kill streak and it lags and you get killed one frag away from a nuke. AHHH. (Still better than CM10 where its around 12FPS all the time).
So im kindly asking someone to build a stock KQM Kernel with the ability for Overclock, and if its possible some shedulers. I think im not the only one who needs this and who would use it all the time.
I would do it myself, but i dont have the hardware for it, my CPU (my pc is from 2006) doesnt support x64 and i cant compile anything on it.
Thank you for your time. :good:
P.S: I know this is dev section, but cmon, who reads the I9000 General?? No one.

64bit OS is not mandatory. 32bit works as well as long as the toolchain supports it. I wouldn't use a VM on 32bit though.
Regarding the KQM kernel.. I would try to find the OC/UV constants on binary level and patch the kernel directly. One possible way would be to compile two minimalistic kernels with both values (stock <> oc) and compare them. If you get the constants apply them to the KQM binary.
On the other hand... the 3.0 kernel is ready. It should kick any 2.3 kernels ass. Probably not worth the hassle at all...
Edit: You could also try to load the kernel directly into decompilers/disassemblers to find the constants. Maybe that's easier...
Very strange. I experienced gaming problems with ICS but not with JB... Very fluent. I am using slimbean!
