Which is the best gaming kernel and rom
.....????

Best gaming kernel ?
The latest AniDroid kernel.
Underclock it to 250MHz @850mV.
Overclock it to 1.6GHz @1300mV.
Undervolt each frequency.
Overclock the GPU to 400MHz.
Install ChainFire Engine from the Market.
The ROM doesn't matter much, but I'd stay clear from TouchWizz because its bloated.
Something like sixstrings's AOKP Build 40. Or ParanoidAndroid v0.5. Or some other ROM.
The most efficient IO is Simple IO governor, aka SIO. Benchmarks show it as weak, but its actually the best one, eveyone knows this.
The most efficient governor for the N7000 is interactiveX.
lulzactiv and pegasusQ don't seem to work well for many people (me included).
When gaming something intensive (GTA3, DeadTrigger, Flash games, etc) you might one to change it to "Performance" governor. But it will drain your battery fast, so have it charging or have a spare battery handy. And remember to deactive "Performance" governor back to interactiveX (or otherwise Hotplug or Ondemand).
Besides this, try experimenting with different set ups. You could get different results, and find what works best for you.
OK. THREAD CAN NOW BE CLOSED. DON'T FORGET THE THANKS BUTTON.

Hi everyone,
Tried various kernels on cm 6.1 rc1 and cfs vs. bfs scheduler with 128mhz to max. Also interactive and ondemand governor.
Anyone like to share in your opinion which kernel_cfs/bfs_governor gives the better battery life , of course stability?
Thanks!

Can some one help with guide on how to overclock. What are the difference schedulers and what does they mean? Also someone can share their PMC Volt setup so I can have a starting reference.
TIA
You can't overclock your CPU until you flash a custom oc kernel on your phone. You have to look in the dev section for those of course. From there on you can use apps like SetCPU or Antutu to overclock your CPU.
Hope this helped

I have flashed MIUI with SwiftExtreme-loc kernel. I want to know how to do the overclocking? I was looking for an example to set voltage and scheduler
Allright in that case try to install the app called Antutu CPU master. With this, you can overclock your CPU. I'm not really sure whether swiftextreme supports governor changing because I'm using IronKernel myself. But if it does then you should be able to change it with Antutu as well. By the way if Antutu doesn't work you can always use SetCPU.
For undervolting you can use the same app but I can't tell you how much you can undervolt because that's different for every device, rom, kernel etc. The best tip I can give you is to try to uv at each frequency and test whether it remains stable.
Note that our devices can't handle any voltages below 770mv.

All above is correct.
Governors aren't useful on your kernels forget about them.
Schedulers are used for read/write operations on sdcard.
Bfq, deadline, anticipatory, cfq, are some of them. They determine the way the kernel will organize the packets of data before reading or writing them.
Anticipatory is mainly efficient with file systems having a journalization feature, that means ext3, ext4, but not vfat or ext2.
Three two preferred seem to be bfq and deadline.
For more details Wikipedia is your friend.
Hello!
Here is a god summary of Linux/Android schedulers...
http://forum.xda-developers.com/showthread.php?p=20895475
For more details you should look into the kernel threads.
You could either go with the preset of your kernel or try setting up your own OV/UV-table using pimp my cpu or set cpu…
…but in case of the SwiftExtremeKernel you could break more than you achieve. If you want to go with this kernel – just leave it as is, because it is already optimized for longer battery life and OC in case it is needed…
If you want more performance you should look into ironkrnL because it is more optimized for responsiveness and faster kick-in of the second core – vodonka did a hybrid of SwiftExtreme and ironkrnL – you could try it.
…just follow the ironkrnL-threat.
I'm using emanoN V4 with No-Frills, and since CM7.1 with SetCPU, I always used 'ondemand' as Governor.
But reading other posts on other devices forums about this, some people say SmartassV2 is the best...
So, as each device is different (specially by the ARM version and manufacturer), I decided to begin this conversation here, and listen to what people with the same device as me has to say about it.
So which Governor do you consider the best for SGM?
Im using cm7.2, setting at nofrilis Governor : SavagedZen io : sio and undervolt at cm setting, give more battery life.
Sory for bad english

sio if u need less laggy n smooth

Thanks for the reply, but as I can see on No-Frills, sio is th I/O Scheduler, that is already set. I'm asking here about the Governor.
Ondemand and set noop
Sent from my GT-S5570 using xda premium
on emanonV4 i use Smartassv2 nd i/o noop
I see that people are very divided between ondemand and SmartassV2.
Now with sio and noop as I/O Scheduler.
Anyone else would like to share?
i will say ondemand because cpu will be set at lowest frequency and when you need it it will set at higher frquency which will save your battery and if you want performance then no lag will be good
The principle of the ondemand governor I'd already figured out (and actually didn't like it, very rough).
I would like to hear more about the principle of the SmartassV2, whereas since this morning I'm using SmartassV2 + noop and I noticed my SGM way smoother than with ondemand + sio.
Now is wait and see if the battery is sucked more.

smartassV2 is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring. Basically it scales CPU based on realtime needs of the system, saV2 supposedly incorporates some more agressive settings for screen off, and I believe quicker scaling than the original smartass.

Thanks a lot, man! And now I think that I had made my choice:
Governor: SmartassV2
I/O Scheduler: noop
Highly recommended!
I just installed Tegrak OC and I am a little mystified on the best setup up for my note. I have Darky rom 3.3 and Franco test Kernal installed. If anyone has this combo and is using Tegrak what have you found to be the best setup for battery and performance together ?
Why do you need to O/C Your note??Its already very quick at processing and overclocking only leads to lesser processor life,battery life and consume lot of power.If I were you,I would leave it as it is
I'm using Tegrak and franco.kernal on stock deodexed rom. I have cpu set at 1600 but don't know enough about the other settings to make any other changes.
I was about to start a thread on this same subject. Thanks ingott77!
@vijai2011 I OC because I have the need for speed!!! And, it actually makes GB run smoother and quicker. I don't yet know if I will use it once the official ICS is released. I've heard the ICS is very quick and smooth compared to GB.

Yeah i have francos test and running 1.6 overclock with the same voltage as stock 1.4ghz (1300mv). Is completely stable for me. Overclocked the gpu too to 267/400. 400mhz is stable for me at 1000mv but may not be for others. Be careful of overheating with 3d games though. Also changed io scheduler to deadline - its francos default but for testing he changed to noop for stability testing.

how i configure CastagnaKernel OV for have max performance without trasform in cheese my cpu? what the governor? the i/o scheduler and the processor mhz?
Sorry for my bad english,but i am an ignorant
OV? Over-volt? do you mean OC? Overclock or UV? Undervolt
smartassV2/SIO (personal favourites)
245mhz/1800mhz (so default settings)
And I think you can better post this in the topic itself, and you will never turn your cpu into cheese, i once ran a benchmark at 2.016Ghz, and it just turned off

I remembered the cranium kernel at 2016 mhz..it became really hot...
Ondemand( little bit tweaked) 368 1804 sio...that s perfect
Q.D.E.
It would be better if you post this on kernel's thread I think there is no need to made a new post about that and sorry but and I'm not trying to be disrespectful. however you can use smartassv2 245-1800mhz that's a good choice.

the combination of default: lulzactive + sio is very performant (CFS version)
or you can try the governor lagfree
if you want the best reactivity using the BFS kernel version,
but is less multitasking
