I have the overcome ROM flashed on my tab and i was wondering if it is already overclocked due to the ext4 kernel or do i need a program to set the overclock speed like setcpu?
which kernal did you install? all of the OC voodoo kernals will say "OC" at the end of them.. its usually a good idea to get setcpu to control your processor anyways.
I have the ext4 kernel installed, I do have setcpu installed too.
The kernal will oc it by itself but using setcpu will allow you to customize your frequency.

Hi,
I'm curently searching for a stock GB V20l Kernel (2.6.32.9) with only overcloking ability.
Thanks
You can try Spica's HP kernel, it's stable and has pretty good battery life. OC can be up to 1.55ghz, but I recommend no more than 1.2 for daily usage
want it too. the very first kernels had just CPU OC, but now all overclock gpu, ram, etc. but my device can't deal with memory OC
up!

Why up? The answer has been given. Horse power kernel is a good kernel, choose SR2 version.
No kernel overclocks gpu, and ram hack exists only in some CM7 kernels.
For me sr2 works great.

Hi I'd like to clarify something.
I've used CF autoroot to get root access, which means I have stock ROM on. I've read elsewhere that in order to undervolt, you need to have a kernel that supports it. The stock ROM/kernel doesn't support undervolting right?
So if I want to undervolt, I must have a different kernel?
yes
Perseus Kernel allows you to undervolt
perseus like stock kernel !
What settings do i have to configure inorder to make cpu scaling less ( sampling and more specifically cpu freq changing )
.. and make it behave more like stock kernel ? ... i only need undervolt! and rest same as samsung defaults !
I want to overclock my N7000's CPU and GPU. Please guide me how to do it safely. :cyclops:
N7000 Intl
Kernel: PhilZ cwm6 v5.06.1 with CWM 6.0.3.2 based recovery
ROM: SlimBean 4.3 (Official Build 2.2-1745)
Your kernel has to allow you to do that and you have to use a program like cpu master, or You can search for overclocking in the settings.

So, what kernel allows you to do that?

The only way to overclock the n7000 worth mentioning
https://play.google.com/store/apps/details?id=com.tegrak.overclock.ultimate&hl=en
For gaming, i recommend:
Also, depending on how you use the phone you might want to underclock(and/or undervolt) the cpu (to avoid thermal throttle) and overclock the gpu (400 mhz works great on my phone, compared to stock 260)
For browsing the web and stuff like that:
consider overclocking the cpu to 1500-1600 (even 1650 has proven possible on my phone.)
try NX kernel (only for 4.2.2) or speedmod kernel.
for me samsung latest update is better for gaming because it has updated driver for mali (and you can use Titanium backup to freeze samsung's unwanted apps)

Can you please give ROM and Kernel details of your N7000? What android version you are on?
I want to overclock for gaming.

I am on asylum rum.
However, on this ROM, my GPU does not scale properly. So for gaming its not great.
NX kernel is great for gaming, unfortunately it's a bit dated.
In my opinion cm 4.3-based Roms work well.
But , changing ROM does not have as big an effect compared to overclocking the GPU.
Here are my speed optimized kernels for samsung touchwiz jellybean, cm11 and aokp kitkat based roms
(many thx to Hank87 http://forum.xda-developers.com/member.php?u=4595544 for testing the many samsung touchwiz test kernels)
V1.2.1:
auto root (tw kernel)
cwm added (tw kernel)
fixed an bug that could make connecting to network very slow
rwsem: steal writing sem for better performance
ondemand: enabled counting iowait as busy for exynos too
kernel fixes for linaro gcc
kernel with AIO enabled
AIO: Don't plug the I/O queue in do_io_submit()
ROW as default io scheduler
build with linaro gcc 4.9.2
kernel build with -Ofast
faux123`s dyn fsync
optimized arm rwsem algorithmfixed an bug that could make the oc kernel unstable
overclock version with 1600mhz max with 16 step frequency table and reduced core voltage
overclock version with 1500mhz max with 15 step frequency table and optimized core voltage
standard version with 1400mhz max with 14 step frequency table and optimized core voltage
on idle cpu can go to 100mhz instead of 200mhz for longer battery life
higher (but save) thermal throttling values
optimized vm values
multithread dexopt enabled

thx for your post.
I will try it and if its working without any problems it comes in the next version
Sounds interresting what GeeckoDev found out. Looks like the new freque. also goot for non playing Note 1 users...
57hz - 59hz is completely safe. If you go beyond that, bootanimation will start to derp (turn off/on the screen once it's fully booted and you're good to go). Also you will have no access to the recovery. I only experienced that on AOSP, though. On Touchwiz I could go to 62hz without a problem. 64hz is fine with the workaround above.
It improves smoothness and lowers latency by quite a good margin (~17ms at 57hz, ~16ms at 60hz, ~15ms at 64hz).
Also, good luck with your kernel!
Had to go back to forest 1.90. On Your kernel cannot use gallery

Hello Bauner
First of all thank u very much for a great kernel. I have tested the non OC and OC 1.5. Everything runs smoothly except for stock video player that got busted with the OC'ed vers just like forest's. I have yet to test battery as I have just completed one battery cycle. Will update if there's anything pops.
Sent from my GT-N7000 using XDA Free mobile app
I also test it for 2 days on DU Rom and it is working smooth. I'm using the non OC version but it seems the kernel loves to stick on 1.1 and 1.4 speed which is why the battery drains much faster.
I also noticed that when Wifi is on and while screen off, it seems to drain also much faster, while on stock it consumes about 150-170mah on this kernel it consumes 230-250mah.
What I'm happy about this kernel though is that it seems to resolve my issue with Dynamic Colors on DU as I had no single reboots while using it. On stock kernel I had reboots when using Dynamic Colors.
Is there a way that instead of always using 1100 speed, it will use a lower frequency like 800 or 900?
Many thanks for the kernel!
Thanks bauner for the great kernel.my note now more energized and smooth after flash with oc1.5ghz tw....antutuscore got 17k..also problem on whatsapp memory leak seems resolved now :beer:

did you try to close all running apps and then check again?
if tehere are running apps that makes i/o can make this kernel running on higer frequencies because my modifications on ondemand.
you could try to use an tool like no-frills cpu control and try another cpu governor like pegasusq or conservative.
with this tool you also can see how long your cpu was running on every frequency

Thanks! Will test maybe tom and change my governor to pegasusq. Hopefully when on normal use it will use a lower frequency instead of 1100. I'm using BetterBatteryStats to see how long each frequency runs and the majority is 1400, 1100 and 100.
About the higher consume of battery, yes there is one app that was running and it was FB messenger though it was also running when I compared it to the stock kernel from DU.
I'll give feedback again once I'm done with testing.
with my rom+kernel it doesn't stay at high frequencies.
the attached screenshot was made a few minutes after boot complete
It says it couldn't mount storage/sdcard0 when trying to mount in recovery.
(KitKat version)
Hi bauner,
Mine also stay highest 1.1ghz..why never reach 1.5ghz..I'm ondemand/row..

It's an app. Nothing to do only follow the guides in the app. Sometimes you need the correct kernel for resetting... try it out.
