Hi, i know this is a stupid question and i have tried to do some research before hand. I have never overclocked any of my android devices, as the worrying that it will decrease you phones life span has always worried me, and the fact that overclocking my old htc desire actually made it unstable. But because the galaxy note had the exact same exynos processor as the s2 but clocked to 1.4ghz. does that mean it's perfectly safe to overclock the cpu to 1.4ghz?
The reason why I am asking is because the galaxy note vs s2 videos on youtube show the note to be noticeably faster in everything. Thanks very much

I run my device at 1.6 with absolute stability. Believe it or not, a lot of the processors released in todays devices are meant to handle much higher speeds, but for battery purposes, they dont push the limits. But to answer your question, yes, its perfectly safe to push it to 1.4, and you probably wont notice any more battery drain then your already used to since they make some battery saver tweaks in the aftermarket kernels. I use Siyahs kernel and its awesome.

Right now the jump between 1ghz to 1.1ghz shows no real world benefit. I have a couple of questions:
1. Does overclocking to 1.1ghz effect the battery enought to see a difference?
2. Does undervolting save battery enough to see a difference?
3. If i have a custom kernal but still running at 1ghz, will the battery be the same/worse/better then runnning 1ghz on stock kernel
4. Does undervolting have any negative effects on performance
Thanks in Advance!! XDA RULES!!

Not trying to be rude, but does not answer my question. Why go through the procedure when someone who has already done it or has experience with it is kind enough to post answers.

1 Yes it does, but the phone only uses that frequency when pushed to limits, so not much.
2 Yes, i believe it does.
3 I found faux kernel to drink my battery like water even oj stock clock. Edgan's didnt have that problem.
4 it may cause random reboots if ur UV lvls are beyond the phone's capabilities.
Ps1: hes got a point, all impressions are too personal, they dont translate to universal experience.
Ps2: the greatest use of OC on the atrix right now is the webtop, that really pushes all possible processing power.

Thank You!
So, I've rooted my phone a couple weeks ago and I've been messing around with different roms and kernels and I thought the reason my phone was crashing at above 748mhz was because of the kernel or rom I had. I've been reading around though and I read that some phones simply can't OC stably like others. Does this mean if my phone crashes a ton at 806mhz and quite a bit at 768mhz that my phone simply can't OC that high? Are there methods to improve my phones OC stability?
Yes that means your phone can't handle that high clocked speeds. Just keep trying to find a stable clock speed. You will probably not find a big difference between 748 or 806.

There are no methods to improve OC stability (AFAIK ). Don't try to OC more than what ur phone can handle.
You can always try other tips from our forum to make ur phone more responsive

try 729/480
should work without crashing
ive tried every rom/kernal combination and with each i get lock ups when doing intensive cpu work such as a game or benchmark overclocked to 1.6 any ideas? Thanks
Just means your processor was built a little weak. Its only built to run at 1.2ghz so anything above that is pushing it hard... some phones can be oc'd that much, some can't. Just take it down to 1.4. I can't even get mine to 1.4 so he thankful
Sent from my AT&T cellular device.
What voltage do you have it at? Try raising it 25mV at a time stressing you cpu at each step until you're stable. That is if you are determined to run 1.6 and i would not push more than +100mV personally.

I do not think entropy is the one who has issues...
This has been discussed in 10 different threads already and in great detail. If the OP did as much as search he would of have found the answer himself. That is why they call it research
the only question left is...... You mad bro?
Keep all voltages stock, then use voltage congrol and click on 1400 and increment the slider+ 25, then do the same for 1600. This is what i had to do to get my phone stable at 1.6 Some phones may need EXTRA voltage and others need less. It takes some testing to get your particular phone stable at anything over 1.2Ghz. I only did it to see if I saw any gains. Actually for me and my phone I found as far as MY SETUP and testing many different benchmark style apps at 1.4Ghz i got better benchmarks than i did at 1.6Ghz. Now everyones phones will act sligbtly different so your mileage may vary.

At 1.6 ghz... your phone will be discharging your battery ON your charger... I personally wouldn't recommend doing it as it gets the phone really hot, and causes the chip lots of stress due to high heat. Personally if you need more performance (this phones pretty damn fast anyways) go to 1.4ghz.
Most of our phones can be overclocked to 1.4 and some can go to 1.6 but not all. If you change the voltages and it still craps out, then take it down a notch to 1.4 and see how that works for you.

Now now. Since when do we encourage keeping things stock.
My point is - if it were guaranteed to hit 1.6, it would be sold as 1.6.
Being able to hit 1.6 is luck of the draw, pure and simple.
There's a reason:
1) OC is not default on my kernel
2) I held off on providing OC support for a while here, and NEVER released it on Infuse (users weren't mature enough to handle it over there)
3) I have a warning in GIANT RED LETTERS not to complain about OC stability issues on my kernel thread.

This is all true... but the OP was simply asking a question now lets all play nice.
We should have an OC that allows n00bs to melt their cpu.... 2.5ghz ftw
No no no.... We have too many "I tried to load the ICS in the I9100 forums, and I bricked my phone, please help!" threads. we don't need "I OC'ed my phone to 8ghz and melted my cpu" threads too
Tegrak allows you to go past 1.6. I thought these CPU were locked @ 1.6 but i had to up my voltage at 1.7 and i got a small bump in my benches though i probably did run my test enough to confirm the bump. At so.e point, when i get some time ill beat on my CPU some more

I ran my phone at 1.6 for days just to see performance. No UV at all.. battery certainly drained faster, but not while charging. It charged just fine.. and stayed cool even when stressing. Like many have stated, all CPU's are slightly different .. just cause yours melts at 1.6 and wont charge doesn't mean this will happen for anyone trying to run 1.6GHz.
sent from my SGSII... suckas
Try bumpin' up the voltage 1-2 notches.
Just to add to the stats...
I've been able to run @ 1.4 with the same voltage as 1.2, but my phone will freeze once in a while when running apps like camera or navigation. Had to bump the voltage up slightly to get it stable, though I will likely just run 1.2.
I cannot run at 1.6.

Try changing or updating your kernel. Im the OP and had the same problems. with the new siyah kernel at 1.6 even if i try i cant make it lock up or freeze.
Your processor was made from a different silicon wafer than other people's phones and was rated for 1.2ghz.
Since each wafer is different, some processors take voltage better than others as well as speed. It happens.

For the people that maintained root through the update; are you able to use an app like setcpu or something to underclock the newly overclocked kernel?
Why would you want to underclock it?
indomfp said:

to improve battery live, but really undervolting would be more useful.
for underclocking, the companion core works much better and is very effecient for standby/basic use senarios.
undervolt won't work until we can flash custom kernels, which need a custom recovery to flash them, which needs an unlocked bootloader.
i don't think apps like setcpu know how to deal with tegra3's 4+1 core setup right now, someone can correct me if i'm wrong
My guess is that the UV/UC battery gains are going to be quite small with the ninja core taking the majority of the strain. There should be some kernel source from nvidia which indicates what the transition is from the different states - maybe the best gain would come from locking out the G processors.
I saw some LP <->G switching info in dmesg with a pre-ICS version, but it seems not to be there any more...
Well the reason I asked was because I'm one of the people who gets nothing but boot loops after the ics update. After trying everything, I was wondering if this could be done, which would narrow the issue down to a kernel problem.

now hat we're unlocked lets overclock and undervolt and see if we can get 10k quadrant and a week out of the battery..lol
no but seriously how much do you guys think we can turn this thing up (overclock) and it be stable? (like its really needed..i cant get it to lag now as it is) once we get a kernel that is

I was looking stuff up on that today. The highest I could find documented was 1900 on the cpu and 800 on the gpu.
For everyday usage, overclocking is useless, even for gaming. Undervolting can be beneficial, but from what I've seen, the latest processors get approximately the same battery life on stock voltage as they do undervolted.

hey thats good to know...like i stated though. if there ever was a phone that needed over clock this one IS NOT it. i cant bog it down right now and believe me ive tried. someone out there might can but i cant.

I just like to play around with different kernels but the kernel I was using def made the device snappier and I had some killer benchmarks! But you are right though! Custom kernels on this device is not really necessary...
I plan on building a custom kernel then, hopefully tomorrow night or possibly Saturday. I do have some plans to improve it, but nothing related to the CPU or GPU going faster, just having other stuff operate better and getting rid of anything not needed.

That's better than me. I could run 1200 for weeks but at 1400 about every other day it would restart randomly.

HA. My TBolt stayed stable at 1200, but ANYTHING higher than that and it would crap out on me.
I could run my bolt stable at 1700 all day. Kept it at 14 for a month no issues. Stayed at 13 the rest of the time. Course at 17 it was like it was running on a watch battery with the amount of time it would last. Lol
Eh I ran 1.6Ghz on my Thunderbolt 24/7 and with the 2750mah battery it lasted me days.
On a phone like that there was a significant improvement to the end user that justified the overclock. Now on the Note 2 I'd expect there to be very few who would want an overclock at all. I am part of the very few however. I play a lot of emulators on my phone and for N64 and Playstation I need all the raw CPU power I can get. Yep, even on this beast of a phone I still get some lag and stuttering on those emulators. The reason being is the same as PC gaming. AMD thinks that by adding more and more cores to their processors they can win the performance arena. Unfortunately they are wrong. Intel has the right idea, 4 cores is plenty now let's improve the efficiency and performance of those specific cores.
Same goes for our phones. Quad core is the most I'd ever want in my computers, anymore is just a waste. Now let's get better architecture for the processor to maximize clock-for-clock performance. And overclocking those cores helps it in apps that don't support more than one or two cores, because the baseline performance for each core is boosted.
So yeah, can't wait for a 1.8Ghz kernel
