How do you undervolt? - Atrix 4G Q&A, Help & Troubleshooting

Hey guys im running faux's enhanced stock kernel on DarkSide v2.1 and I was wondering how I can undervolt it?

Just download setcpu and then go to voltages and set them to how you want
To give you an idea of what settings people usually use, some people posted their working settings in this forum

SetCPU not working? Even with root and custom kernel

So I have my atrix rooted, running Alien Rom #4 with Fauxs Kernel! (2.6.32.9-MB860-GB-Faux123-v0.2.0 [email protected]#3) so it is supposed to let me overclock but when I use SetCPU app my only scaling options are performance and powersave and I can't get the CPU up to more than the default 1GHz. Why is that?? I was trying to overclock to 1,1 or 1,2 but it doesn't go past the 1GHz.
Someone knows what's happening here??

That's not the overclocked kernel. You need the 1.3 one if you want to go over 1GHz.

Oh Thanks a lot bro!

Disable Overclocking in ICS Passion v11

I just upgraded to ICS Passion V11 and want to know if it already overclocks me to 1.4? If yes how can we stop the overclocking.
Thanks.
Get voltage control from market it should be free.
Check your OC it shouldn't be OC stock though

You are right, it wasnt OC , I was confused as it was mentioned by neobuddy in the ROM post

[Q] underclocking problem on my phone

i having a underclocking problem on my galaxy s2 (4.0.3 LP2), when i set my cpu to 1GH or 800mhz , my phone will hang and i need to force shut down
even i use Battery Saver Pro app also hang.....

Have you done undervolt also?
This is the main cause.
The problem is from your kernel
what kernel are you on, to overclock the best kernel is siyah kernel for ics roms
SiyahKernel for SGS2 | "One kernel to rule them all"
www.gokhanmoral.com
once you do this you should't have a problem anymore
if i helped press thx

Said the man who just posted that there are no stable ICS ROMs.
Great advice about overclocking though - the OP obviously really wants to, he just ended up underclocking buy some twist of fate... Good you're here to fix it for him
You cannot possibly be for real.
may i know how to undervolt and what app should i need to use to underclocking/overclocking?
i used battery saver pro to underclocking but my phone hang and force shutdown
Sent from my GT-N7000 using xda premium
i flashed siyah kernel,now i can set my cpu and no hang occur
thanks for helping me

anybody know how to set the voltage using cpu master pro app and how many need to set

The Principles of Overclocking an existing Kernel

Hey guys so what I want to know ... Is there a way to overclock the Kernel that is in your phone. I found the files that tell the Kernel what the maximum clock speed is, and I changed them all BUT the phone kept changing them back. I have su access. Any ideas?
No-frills CPU Control, you can find it in the Play Store for free.

Hey there
This isn't correct, you can't overclock a Kernel using CPU control. You can increase the clock speed to the maximum allowed within the kernel but that isn't technically overclocking. I want to change the modules without flashing a whole new kernel. Any ideas?
Thanks
Carl.

[Q] Setting CPU speed

Hello all, i have a question, i am using the Phenomenal 3.0 normal version kernel and is using SETCPU apps to manage my CPU speed. However, when i try to set the speed to 1100mhz and above, the CPU speed does not go up to 1100mhz and above, instead it always stay at 1000mhz.
Has anyone experinece this before? if yes, has anyone any steps to resolve this?
Could it be the undervolt issue that is preventing me for going up to 1100mhz?
Thanks.
Looking at the thread it doesn't look like the kernel has overclock capabilities,

I am not trying to overclock, just trying to go to 1400mhz at times but i just cant go past 1000mhz, only when i restart the phone, then it will go to 1400 at times...
seem like i have solve the problem by untick the cpu power saving under the power saving option. However, it seem like the SetCPU apps is useless as i am unable to control the CPU anymore.. is that true? or are there any apps that can overcome this issue?

Have you tried using other apps, instead of SetCPU, or are you running two CPU-manipulation apps at once?
Try clearing SetCPU's data/cache and try again
I personally use AnTuTu CPU Master, but that is a personal choice, I guess

I have SETCPU and system tuner pro... does these 2 apps cause the issue that i have?
Phenomenal kernel is a ready to use kernel. You cannot change any settings here in this kernel. It's not like any other kernel wherein gives you the ability to configure the cpu and gpu. Setcpu will only work with other kernels such as SiyahKernel. This will give you the ability to set the cpu and gpu freq and voltage. The power saving mode limits the power of your cpu, thus disabling it will increase cpu freq

Hi, thanks for the info and advise, so can i ask if i revert back to Stock Kernel, i should be able to control my CPU speed?

No u need a kernel with cpu freq altering capability integrated. Siyah kernel has this I know

I use Tegrak Overclock on stock rooted ROMs. It goes to 1.6Ghz. Works perfectly.

Nope. Stock kernel will not allow you to change it. If you're on stock ics rom, i would suggest you use siyah kernel v1.5.2. I'm once a user of it. If you need a guide in underclocking and undervolting, you can find the best guide here posted by bala_gamer. You can also settings in his signature which you can use.

Read my post above. With Tegrak you can overclock stock rooted ROMs.

Yes sir I know. But I just want to give other options. So that he can choose which is good for him. He can overclock upto 1800mhz in siyah kernel. But afaik, he is more on overclocking with undervolting to have performance and battery life.

Thank you all for your good advise... now i know why i cant set my CPU speed due to kernel.
Will look into trying other kernel if i really like to control my CPU.

Nope. Pretty straightforward and it's been around for a while now. Used it with my Galaxy S II as well.

And you are very right!!!!! Doesnt matter what app you use u cant overclock on stock kernel!!!! Stock kernel doesnt have the provision for that. And if members who send links read those links properly before they send them they will realise that you need a kernel that supports overclocking like siyah!!!!!!!!!!!! Stock kernel doesnt.

You need to actually go look at the Tegrak app before you start typing....
