Hi all this is my boot with support of ext2,ext3,ext4 overclock to 1600 Mhz..

If you wan't use setcpu, phone will run at 1017 Mhz by default and minimum speed will be 123 Mhz

Voltage is lower than standard boot, so you'll have most battery duration and less hot device :P

Thank to Vache that help me to build this boot and thank to Singulus that give me a beautiful boot logo :D

To install use amonra recovery by Vache..

Using deploy 1 seems it's the right way..

Newboot is not the same of original boot but taking the first line of original boot with hex editor and put in newboot it works so i'm sure that is a problem in repack but what?

I've compiled kernel whit .config token from Metalounay, but i've miss overcklock :)

I've to change some parameter in some source file?

EDIT: I find this file acpuclock-7x30.c

I think is that file to edit.. I'm saying right?!

I see also that inside this file there is VDD_RAW table.. Is the voltage of CPU?

I don't want to fire my liquid..

If edit this file give possibility to overclock please give me right table or right file :D :D

I think that i should wait for a final boot.img including all of these tweaks! :D

Give a try i need battery drain feedback..

To me is very good but i want some feedback ..

And also about general smoot and speed

Of course! Thank you, i remembered! I will test and let you know! :D

First of all do a nandroid backup

Obviously when you do fastboot write the right name of boot

adb reboot bootloader

fastboot -i 0x0502 flash boot bootdmd_oc.img

fastboot -i 0x0502 reboot

When phone has reboot set with setcpu min freq to 122880

very good joob, but sorry but the link don't work.

So, if I lower the voltage of cpu, the cpu is stable on 122 mhz than normal voltage????

Yes is stable. 122 Mhz is frequency not voltage..

Voltage is regulated by kernel according to a table..

Any cpu frequancy has right cpu voltage so when frequency change also voltage change.

You can't change voltage without modifying kernel, but you can change frequency..

Link is working to me
