Rom cookers: if you include this module in your ROM, please make a link to this post in your release post, so your users can know how to work with it and update the module themselves

Well, it seems that many people don't want to overclock because of heat, stability..., and just want to have benefits of an undervolted cpu. So here it is my friends. Default voltage level of our kernel is 3-4-5-6-7.

Source on github :

Release history
  • April 20. v001. Undervolted at the level like X8Overclock: 0-2-3-5-7. If you have sudden reboots with out "SD card safe to remove", please report here.

- Rooted
- Baseband x15

Manual installation: it will be better if you can do this way. From now on I will not provide for xRecovery, because there are some different modules now.
- Download appropriate (for X8), or (for X10 mini), or (for x10 mini pro) below, unzip
- Remount /system as rw
- Push x8uv.ko in to /system/lib/modules
- Edit /system/etc/, add one line at the beginning
insmod /system/lib/modules/x8uv.ko # x8 undervolt
This module is dangerous! It may lead to system instability and may damage your hardware. I'm not responsible if this module kills your lovely phone. Use it at your own risk!

I am not able to do overvolt now, if you can, contribute :) Don't just say obvious things that I've known since the beginning.

you're a great guy doixanh.
i want to ask, what sort of problem that COULD occur after installing this module? does this module have anything related to sd card safe to remove problem?
20th April 2011, 02:00 PM |#8  
Problems may include : strange behavior, crash, reboot, force close apps... etc...

But because many people are running undervolted with x8overclock with (almost) no problem, you don't have to worry :)

Can be used in combination with x8oc.ko as I can adjust the combination of the two modules
