Stable voltage for undervolting

bekasulaberidze · Jun 6, 2014

Hello guys if you have note 3 (sm-n900) with Kernel -halaszk-UNIVERSAL5420- and want to undervolt your CPU I have found a stable voltage for undervolting, Use SetCpu, first of all set your CPU when you are playing huge games to avoid overheating to min.200 max1300Ghz.

200Mhz-700mv
250-750
300-775
350-825
400-850
450-875
500-925
550-975
600-1025
650-1075
800-750
900-800
1000-825
1100-850
1200-875
1300-950 or 975

If your device overheats after undervolting I recommend to use DVFS disabler.

Do keep in mind, that there are not 2 exactly same devices. There is no stable voltage, which works for all phones with that model number.

Need help

I am using N-900 running Lollipop stock rom 5.0
I wanna do undervolting the cpu for long lasting battery life without flashing new mod rom.
Please give me some advice or recommended kernel for stock rom supporting an undervolt method.
Thank you in advance.

1) What is DVFS?
2) Underclock to 200mhz is NOT POSSIBLE!
3) There no undervolting, because my phone stock volt for 300Mhz is 775Mhz, which i use for 300Mhz is 700Mhz and no reboot, nothing. Just bit longer battery life.
4) Setting for 300Mhz-1300Mhz for gaming isn't recommend i. Just enabler Samsung Stock Power Saving. It's limited CPU to 1700Mhz with MCPS (Multi-core Power Saving) with Bettery thermal options and GPU framerates limits to 30FPS for slightly save power and slightly reduce overheating.

Thanks
