Cm9 compatible kernel w/ undervolt?

Hey guys, could you recommend me a kernel for my gio running CM9 that also has under and overvolt capabilites, without giving up things like the init.d support and cpu scaling?

Gio doesnt support it, it cant..

Why is that?

Because of the cheap arm v6. It cant be undervolted

Allowing your CPU to lower its volt consumption then its stock value , mostly done on PC's..

Simple way:
You charge your battery with energy. The processor needs energy to run. It takes energy out of the battery with the same amount in a timezone. With undervolting you can set this value under its normal value, so it consumes less energy and saves your energy stored in your battery for your screen, wifi, data connection etc what consumes energy stored in the battery..

lol 0.o if u compile a complete new kernel
u can set the Voltage Use while Overclocking -.-
So if it is over seven its Overvolt
It is under 7 its Undervolt
so are u a kernel Dev to say something like that?

Why dont we have one then? Because it can ruin your cpu..
Phiexz and delanoister are great devs, they also made kernels..
And it problably doesnt work well because otherwise we would have it

Okay, is that why games like temple run are not compatible with us either? Also, if you know, what is the difference between it and other processors that makes it undervolt incompatible?

Temple run isnt supported officially, so it is modified to work, but arm v6 is old and cant handle it smoothly, thats why they dont give official support..

Ah makes sense. To bad though. :/

Yup undervolt gives much lower performance but any device is able to do that ;-)

Kernel Evoluation ROM

Hi everyone, first sorry for my english I'll try to do my best ^ ^
Firstly i would like to install this ROM http://forum.xda-developers.com/showthread.php?t=1757125
but before i read here in this post "Main features :8.It HAS UNDERVOLT support.It is undervolted by 120mV by-default...This is not for noobs.I repeat,it's not for noobs.It'll easily screw up your phone if you are not carefull"
Then some com's after "-120 mV is pretty much aggresive for starters. -100 mV is more stable."
I'm really noob, so to change this value will need some experience in this domain
My question is, if i leave this value -120mV it could destory my phone or brick ?
Thanks all lov u <3 !

The worst thing that can happen with undervolting is that when the processor is under load the phone will reboot

Thx for ur answer! another question ^^
how it can upgrade the performance of my phone ? i dont know how its important and what that can change exactly plz ?
sorry my english is very poor

It won't improve performance, it will just extend your battery life.

Dont worry the only bad thing that ever happened to me was when playing fruit ninja and the game just hanged. The game only. I was still able to open task manager and close it. I undervolted by 140.

For gaming it will lag at - 120 mv. But battery life will be increased by a lot. - 100 mv for both balanced battery life and times performance who likes more gaming

It depends if you use more min-max cpu frequency. Decreasing them will cause lag with -140mV. -120/100 is stable even at low frequencies.

Overheat

Sry for a maybe stupid question but my Arc S is always very hot, especially when it's charging. I downloaded the Phone Temperature app and it said that my temp is 54 °C and I'm very worried, I hope that my camera lent won't melt becouse it's starting to be very hot.
Hope someone can help me.

Hi! Same issue here...
Could be a solution to downclock the CPU to 1ghz? Someone tried that way?

Of course it would, but that isn't really a solution, it's a workaround with sacrifice of speed.
I highly doubt anything will melt inside the cell phone. They must've tested it and all, I'm sure they noticed it gets hot. Otherwise there's always warranty and stuff

I changed a few things and it work for now, u dont need to undervolt or anything..I downloaded Ram manager Free on google play and then set it on Balance..it a daily use option (u have other options too) so now the cpu is at 1400mhz only when my phone needs that much, and when I do other stuff is at 1000mhz sometimes even lower. It's not slower or anything, it just saves your cpu for when you need it.
Pls hit thanks if I helped!

It's not a stupid question, however it is misplaced.

54 ° is very a high temperature no? in my arc s the max temp is 42-43 ,when playing ,and its 33 ° while it's charging ,without using it off-course

It is due to heavy OC. If you dont want lower your OC value.. there are few steps to keep your phone
normal while charging!!
Dont play games or use heavy aaps while charging.
Switch off WIFI / 3G during charge.
If you just let your device sleep during charge.. it wont heat up!!

The only problem when it get's really hot is when your charging and playing games at the same time, the touchscreen is really very hot.

I had the same on CM9 nightlies. Stock ICS based ROMs don't heat my Anzu.

does jelly sandwhich rom overheat your arc s???

My arc s only get hot while gaming

I didnt really know how hot is my phone..Just do think of "too hot" after doing a BackUp and then flash a new ROM.

Mine usually gets hotter while using 3g!

overclocking

i have overclock my phone to 1.6 G.H it awesome in hard games
can any one tell me what the maximum time can i overcloced my phone when i playing games
AND what will happen if i use overclock at 1.6 all the day ? any one try it ?

Overlocking its different from phone to phone ! Some w can take big oc and some just crash
U have to test for yourself since every w has unique hardware

Could be voltage or thermal settings too, I have Ktoonsez kernel with Infamous S4 Rom, and I undervolt the voltage for everything and my phone doesn't get all that warm anymore.

I use SetCpu to maintain kernel settings, I keep max speed to 1.3 ghz and min to 162mhz, and under it there is a spot to undervolt, I do -50 on that... thats pretty much it, governor is "ondemand" and scheduler is "cfq"

It's natural for this phone to get hot. It's only overheating when its shutting itself off or acting strange once it gets hot.
It's normal for the cpu temps to go to the 70C range when doing heavy applications.
I would recommend a custom ROM, with KT's Kernel. The Custom ROMS normally offer a much debloated solution with some minor optimizations which does reduce background tasks on the phone allowing the CPU to run at lower frequencies which helps maintain a cooler temperature.
KT's Kernel also has several options such as undervolting, lowering max frequencies, governors, and tweaks that also will help keep the CPU running cooler. Altogether you get extra battery life, a cooler phone, less garbage that you have just sitting on your device.
If you want to stay stock, that's fine, but it's normal to get hot to the touch.

As Monkz said, is completely normal. If you're playing an online game or
one that has good graphics, it's bound to be hot.
