Minimum CPU frequencies won't stick - Android Q&A, Help & Troubleshooting

Whenever I try to set minimum CPU frequencies higher than the default value, no matter what app I'm using or what kernel or Rom it just won't stick. Governors and maximum frequencies stick though. Is there any way around this? Thanks in advance!

Minimum should be changed a lot, you're phone will overheat in no time
For best performance overclock the cpu to the max stable level and use the performance govenor
Hope it helped!

SETCPU

Hey guys,
What is the difference between the different profiles, ie.
On-demand
Performance
Conservative
Also, is their an app that monitors cpu voltage and cpu temp?

Tegrak settings for i777?

I've been using SetCPU for profiles, OC, and UV my phone. However I notice that the Tegrak OC app gives the user more control with tuning the GPU and I/O scheduler in addition to everything that SetCPU offers. Can someone who's been using Tegrak for awhile provide their voltage settings (since its more detailed than the voltages in SetCPU) and if possible any GPU settings/voltages. Also does using a certain I/O scheduler results in a noticeable improvement in performance or day to day usage?

ok only thing ive played with is just overclocking and using the noop scheduler.

What do you use for setting the CPU?

Which app do you use to set the CPU on your note?
Sent from my SAMSUNG-SGH-I717 using XDA
System tuner
Sent from a Galaxy far, far away!
antutu cpu
Had an HTC Evo prior to my Note and swore to SetCPU, but now its Screen Off profile is unnecessary with a phone that deep sleeps.
I use System Tuner now.
702MHz max
192Mhz min
On demand governor
AnTuTu CPU Master.

I doubt your kernel has anything to do with it because Siyah's kernel does support both OC and UC. Do you have any profiles that have a maximum of 1200Mhz instead of 1000Mhz? Those could be kicking in even when you don't want them to if you aren't careful.

Nope I'm not using any profiles. Although in CWM in kernel specific options I did select performance mode if that has any thing to do with it
Sent from my SGH-I777 using xda premium
Try deselecting that option or selecting a different one. I don't have a ton of experience with Siyah, but a performance mode sounds to me like it will default to the maximum CPU speed. Which on the SGH-I777 is 1200Mhz, stock.

Ok I will try that out

Performance is a Governor for the CPU that sets it to Max frequency . That's what its FOR. So its doing what its supposed to. As previously stated you have to switch to a different governor in order to underclock.

I'm not talking about the governor in CWM there is a option for default, battery and performance
Sent from my SGH-I777 using xda premium
No, he doesn't mean anything to do with CWM. When you're selecting or switching to a governor, a list comes up and depending on the governor, your CPU will behave a certain way. If the maximum is set at 1200Mhz and is going to that speed when you have performance governor on, that's what is supposed to happen.

Uninstall any other clocking apps and clear application data (manage applications) for SetCPU.

Change your governer to something other than lulzactive.
lulzactive forces your CPU at a certain rate. Thus, the "active". and the "lulz" on my end.

Changing clock frequency on stock kernel

Is it possible to underclock the stock kernel using SetCPU? I tried setting max freq to 800 MHz but the phone rebooted. What is the reason for this?
Sent from my GT-I9100 using xda app-developers app
Because stock kernel doesn't allow to OC/UC.

Use Voltage Control (VC) app from Play store.
As long as you stay between the min. and max. frequency range of the stock kernel (200 MHz - 1200 MHz), you can change the maximum frequency to 800 MHz.
Don't foget to store bootsettings (via VC app menu) as service after changing the max. freq., so that this will be applied after each reboot.
