I have a question...
If my kernel is currently undervolted by -25mv by default in the rom that I am using, if I want -75mv TOTAL undervolt (from stock levels), would I need to choose -50mv or -75mv in aroma?
Does anybody know?
Thanks.
Hi,
It is possible but may conflict.
You should turn your ROM UV to 0 and make the kernel UV to 75.
-75. Better yet, configure from apps such as Kernel Tuner.

Can i use No frills CPU or any other cpu controller with stock rom and kernel?
Yes I believe you can as long as your rooted.

Yes, you can. However you won't be able to overclock anything since the stock kernel doesn't support that. You can only change governors and I/O scedulers. If you want to stay on the stock kernel but have the ability to overclock/undervolt, you can try SebastianFM's kernels.
I also tried to overclock my CPU with stock kernel. Is does not work and changing the governors just makes the phone a bit slower for me cause the kernel doesn't really support is. Try senseomaniac rom, has the bricked kernel. I am using now and works great.

You don't have to change ROM to use another kernel . If changing the governors makes your phone slower, you probably tried 'conservative' or 'powersave'.
Yeah I know for only changing kernel, but is much easier to flask complete rom then only kernel, kernels differ and are many for different phone roms made for spicific phone then kernel will work. I had screen off governor set to 1cpu and 192 fq, made the unlock slow

No i was unable to use No frills, i set min to 192Mhz, in the application it says 192Mhz but actually it stays at 384Mhz.
I think he meant stock rom. You need a custom kernel to change the frequencies and voltage, that includes lowering the lowest possible frequency (384 to 192).
Yes, i apologise, min was 384. Didnt pay much attention to the numbers
okay, so i flashed a kernel recently and it came with the smartassV2 governor. when i set it to this i notice that it jumps frequencies, and stays doing this. is this normal with this governor? and if it isn't how can i fix it?
PS: I'm running trickdroid v6.20 [TMOBILE]
with fusion ultimate kernel v1.0

This should answer your questions.

Will using Setcpu allow me to overclock the cpu on rooted stock 4.0.4 or does the stock kernel not allow it?
Use the oc method from here
http://forum.xda-developers.com/showthread.php?t=1648421
@Mtn - While not wanting to deviate from the OP, correct me if I am wrong but OP mentions stock 4.0.4 whereas your link points to ScV7 based on ics leak for the OC method. So will it work?
Also would appreciate if you could advise which one is better, SetCPU, AnTuTu CPU Master, Android Overclock (J Rummy). My primary question is after ICS OTA the Cpu has automatically scaled up to 1200 so what will be the safest OC value therefore without destabilizing the system?

Those overclock modules will work on any ics version for the A2. Rdavict's flashable zip is the easiest method. Personally i use nofrills cpu and as far as oc values that differs from chip to chip. My first A2 would do almost 1.4 while my new one gets flaky after 1.3
Go here and at the bottom of the first post download the tweakerz alpha app.with it you can adjust clock speed and voltage quickly but it wont stick through a reboot. So if you set a bad oc you wont be sol

:good: Noted all @ Mtn..very insightful and needs much reading before I can start asking any questions

That app sure makes it simple.
I'm curious of whether it's okay to run no-frills CPU with stock JB, as it doesn't seem to have a CPU governor.

Is it recommended or needed?
Thanks!
On the stock kernel, it won't do you a ton of good... And you will have to be rooted to use it.
thanks, I'm rooted.
The reason it won't do me a good must have been that the stock already has a governor or something ???

Stock kernel doesn't allow for under/overclocking... I guess there are a couple of governors on the stock kernel, so you could change those around?
Custom kernels give you options like under/overclocking, different governors, different schedulers... etc.
So there's no reason you can't put NoFrills or any other CPU control app on a stock kernel, you just won't get a whole lot of choices with the stock kernel
Running MOAR v2 and stock NE5 kernel. Downloaded Trickster MOD and trying to mess with the min/max of CPU frequency to save battery when I don't plan on being on my phone a lot.... but the min/max never seem to save, is it the app or something I may be doing wrong? Thanks in advance!
BTW- What I am trying to do is: scheduler= CFQ; governor= Conservative; Min= 422; Max= 1497
Stock kernel's typically can't have clocks adjusted, you'll have to go with a custom kernel.

Funny bc I'm doing it as we speak with Trickster MOD app!
