I'm on stock but rooted, wanna underclock to try to save battery... thanks!
Why not just lower the max frequency? Can be done with any of a bunch of kernel apps.

That's what I am trying to do, I thought it needs kernel support, no? I used to use Trickster Mod on N5...
Not sure how it works on Lollipop, but previously all you needed was root. Then use a kernel app that allows you to set min and max frequencies. Undervolting 'may' require a kernel that supports it.
Under clocking below stock kernel min. frequency would require a different kernel of course.

Hi everyone,
I just have a little question.
It seems that when installing Fugumod kernel, users (including me) start to experience some lags on some (unknown to me) circumstances. These lags are easily solved by setting the min frequency to 166 MHz (I do that with pimp my cpu). My question is : Is that behaviour different than with the stock kernel ? I mean what is the min frequency on the stock kernel ? 83 MHz like the fugumod kernel ? Setting 166MHz as min frequency is a patch or is it just putting back the same value as the stock kernel ?
I known that I could easily test it by myself just by putting back a stock kernel over my fugumod kernel, but I already converted all three FS to ext2/ext4.
And btw, i like my Fugumod kernel so thanks to Sebastien and the others for their work.
Fred.

yes the default freq for the CPU are 667-83 and if want to use THE DEFAULT freq than flash a non OC version of FUGUMOD

Thanks, but that was not my question ;-)
I simply want to known what is the behavior of a stock kernel regarding cpu freq. Is the min frequency on a stock kernel also 83 MHz or something else ?
Fred.
I think the main problem is the governor, or wrongly chosen governor that keeps the cpu stuck too low

My mistake, as you talked about fugumod OC, I though you were referring default freq range for FuguMod instead of the stock one.

Thanks, but it lead to other questions ;-)
What is the default governor of a stock kernel ?
As I am using FuguMod 2.4 800, and PimpMyCpu tells me that there's no governor, is it safe to assume that it's the same governor on my FuguMod version and on the stock kernel. If so, why lags on Fugumod?
And finally, on Fugumod kernel what would be the best governor. My aim is more battery conservation than pure performance, yet these lags @83MHz are extremely annoying.
Thanks,
Fred.
well on my i phone i also prefer to use the conservative governor but when it comes to play heavy games i change the governor to performance.
for saving battery make a screen off profile with max frequency 166 or just a bit more that that...
it saved a lot of my battery...
Does gingerxperia support overclock by itself?
I see in cyanogenmod setting overclock option and when i change it to (for ex. 729 mhz) i go back to home screen and the return to overclock setting i see it return to default (600 mhz). Why?!!
Also SetCPU doesn't work!
Do i have to install custom kernal??
*In MiniCM-7 overclock works fine from cyanogenmod settings.

You have to instal either the OC Module for stock kernel or any custom kernel which supports OC'ing. Are you sure it worked in MiniCM-7, except from having the ability to check the new amount of MHz?

you mean this: Modules for stock kernel.: Flash with CWM. This package contains: AnDyX's Dualtouch for Cypress, AnDyX's smartass governor, ext3/4, X8Gesture, X8MDDI, X8UV.
but what is that "smartass governor and the x8mddi"??

x8 mddi is a module that reduce the lag experienced by all custom roms. governor is the way the phone control the cpu. smartass governor operates by reducing ur cpu speed when the screen is off and increasing it when the screen is on.

Im used before Gingerxperia v17 with stock kernel 2.6.29 and it allowed overclocking.No problems!Now i using same ROM with nAa kernel 2.6.29-nAa-08 and have no issues.Do you know when you will install custom kernel you MUST have opened bootloader!
overclock
i have 2.6.29 and i cant overclock my x8 , can anybody help me....plz
Is it possible to overclock this phone? The kernels available don't seem to have ability to overclock and/or undervolt. Is this not possible?

Squid and Optimus are already undervolted and slightly overclocked. Also HERE is undervolted stock CM13 kernel.
Hi guys
does anyone know the min and max cpu values of both cpu cluster on stock kernel?
thanks!

Hi... I don't have them in mind and actually running EX Kernel... Since nobody seems to answer, the best way for you to find out is to install it and check by yourself with a kernel manager app: Kernel Adiutor, EX Kernel Manager, etc... It should normally cost you a maximum of 15 minutes of your time... :good:
Good luck...
Hello everyone, my cpu frequencies are going insane. I cant lock them to minimum and maximum frequencies using any kernel tuning apps. I'm in invicta OS right now.... It happens in every custom rom and custom kernel I tried so far. The cpu governors keep resetting to default governor. :crying: Is there any solution for this issue?

Please describe some more details: device XT... , rom and version, which kernel tuning apps etc., does kernel apps receive root access, do you set it at boot so the settings won't be reset after reboot?

XT1643 in invicta OS Rom with default kernel, root privileges were given to kernel adiutor app, busybox is installed and set on boot is on but still the frequencies go insane like they're drunk and it's heating up my phone. I had same issues with all custom roms and custom kernels. I tried different tuning apps from playstore but the result is same.

As you can see the screenshots.... The minimum frequency i set is to 400mhz for cpu... But after sometime the minimum frequency sets itself to 900mhz....... And this change in frequencies is heating up my device. Why can't i lockdown the minimum and Maximum frequencies? does it have anything to do with cpu hotplug provided in invicta os?

Applicable to all kernels, and kernel managers. I would suggest you try the Lightning Blade profile (check the forum, it's here. Search.) as it has always kept my device cool.
