I OC my n7 to 1.5 and 51mhz and when I play games like mc4 the CPU gets to 70 are higher is that bad or good please help me.

Yes, it is really bad
As long as you don't push it behind 80°C you should be fine. But as always with silicon, the cooler the better longivity.

It never hits 80 only 70-75 and are you sure this is bad? And what should I OC it to?

K I put it at 1.5 and 204mhz is it still bad ?
The effects of heat are cumulative. Same thing for temperature cycling on material work-effects (e.g. fracture mechanics)
That means that a lower temperature for an extremely long time can be worse than a high temperature for a short time. There is no magic "you are safe below this temperature" assurance that can be handed out.
If you use your device hard, you will wear it out sooner - on average. (What an individual device will experience can not be predicted in advance.)

So what is the best Overclock settings for the motley kernel and what is the safe zone for my CPU while gaming or browsing or YouTube?

Try it and find out.
What is this?? Read the kernel thread. Why would you install a kernel without knowing anything about it?
I read everything about it.... I just need some good oc settings so it won't hit 70 while gaming or is it normal to get that high while playing intensive games?

There is nothing magical about 70C.
For long-duration loads (say gaming for several hours straight), the CPU temperature rise will be a certain temperature rise above ambient for that load condition - so somebody gaming outdoors in the tropics will experience a higher CPU temp than someone indoors in air conditioning.
My tablet (stock rooted) idles at about 38-40C with the screen on in a room at 20C (68F). Call that a 20C rise above ambient for an "idle, screen-on" condition.
I have coded a threaded native program meant to saturate each CPU core as well as the memory bus (& tweaked it for max temperature rise); when running it simultaneously with a long-lived graphics benchmark, I have seen peak cpu temps of 85C. This corresponds to a 65C rise over ambient. This is a ridiculous load, though.
As mentioned elsewhere, the stock kernel has thermal protection mechanisms: a rate throttle at 95C and an emergency shutdown at 100C. With that (above) ridiculous load, I couldn't get there with 4 cores @ 1.2 GHz. It is possible that by running the same load for many hours continuously (or inside a hot car) it might hit that limit though.
But I don't think that the existence of an emergency shut-off means that below that temperature means "your device won't experience long-term degradation" - more likely that emergency shutdown is there to prevent somebody's defective tablet from burning down a house. Asus/Google are much more concerned about tort lawyers and product liability lawsuits than they are about the longevity of somebody's stupid $200 tablet... that has an invalidated warranty.
If you are gaming for an hour or so at a time, 70 or 75C is probably not going to cause an immediate hardware failure.
Your tablet is made out of a bunch of materials that are subject to a variety of failure mechanisms. Every one of those mechanisms proceed at a faster rate at higher temperatures. (Remember the old rule of thumb "reaction rates double for every 10C rise in temperature"?)
So, enjoy your tablet for gaming. But don't leave the performance governor enabled all the time: your device will spend more time over the course of its life in an idle condition than actually doing anything for you - there is no point in you cooking it slowly to death while it does nothing useful for you.
cheers
You're right but I get 70c in a matter of minutes I think I'm just gonna retire from oc and stick with the stock kernel

You can do it with M-kernel and trickster mod

I can't stress enough the importance of voltages to temps. On stock Trinity kernel I ran 1.6ghz at "default" voltages (can't remember how much, something like 1.2v) and hit temps of 95c.
I dropped it down to 1.125v and my temps went down to a max of 75c and usually much cooler.
Anyways, you'd be surprised just how much the voltage affects the temps.
Good luck guys!

There are different settings, Ondemand, Performance, etc. What should it be set to to get best performance and does the Set to Boot box be check marked off?
You mean XOOM overclock, right?
interactive is more responsive and use a Tad more resources than ondemand. For the XOOM being dual core interactive is fine. On demand requires a signal to increase speed whereas interactive just does it. I wouldn't set at boot until you know your settings are perfect. Set at boot sets the speed at boot rather than having to go in and raise or adjust speeds.
1.5 ghz and interactive work wonders for me.
Lol I'm probably the only one but I love performance/start on boot. My batt still lasts days and I never have to worry about touching a thing.

Hy XDA,
I have a simple question:
Why does my phone turn off if i OC it too high?
Cpu can't handle it or battery overheat?

But Which?
All theese too?
Anyway i'll make a test:
I will OC higher and higher and run a Quadrant Benchmark, while holding my phone in front of a 90cm fan, without the phone's back cover
Will report the test's performance ^^
Sent from my GT-S5830 using xda premium
Its due to the cpu, every cpu is different, their tolerant limits for oc are different, you should oc the processor only uptill the point where it runs without any reboot.
Do not cross the safety limit, it might damage your processor.
Oh man. Accidentally pressed the thanks button again.
Volkswagen is cool and I hope to own one.
No problem, there we go there is a Big Thanks for you too

I got the phone 3 days ago and when i ran benchmarks (antutu and quadrant) they showed my atrix running at 1512 mhz. Now they show 1134mhz. This wiuld be easy to fix/ confirm if we had root.
The Phone also gets kinda got but i think that's normal.

Did u run the benchmarks with low battery? Do u have any sort of power management apps installed??

At first i did run with low battery but now i have full charge and no power management settings... i even fxz-ed to stock (just in case) and still the same

I have noticed mine clocking at 1512 for half the antutu test, then it clocks it self at 1134 or 1311. Phone does get a big sluggish in some games.
Hi Guys.
What is overclock and how to get it.
Wats the use of it.
I am using project X
Overclock is the process of changing the frequency of the processor to a higher value. The use of it is to make the phone faster (nof sure of this). And of course if you overclock, your phone's battery will die faster. There's undervolting too.
You can get it by using apps like SetCPU from the play store. You also need a kernel with OC support e.g. Redux kernel, xs-ics.

Spot on zukri
On a basic level, if dome right it should make the phone more responsive, faster, smoother. It will raise the voltage which raises heat and more voltage is drawn from the battery though

Fastest mean 1350 Mhz available in Zeus, but on safeside...1100 is preferrable of most users and is recommended.
In view of voltage (0) default is good.
InteractiveX is the latest and gives better battery backup..

For me,Best overclock is 1300MHz(you can put 1350 if you'd like)governor is smartass v2 and i/o scheduler is deadline.That is good enough for gaming and other stuff.For undervolt,go as" under" as you want

After studying on all Sources, Undervolting renders little or no use to saving power. It also reduces your performance. Take note.

You can't OC that much without pushing voltage up aswel.
What do you recommend changing the voltage to if I'm going to overclock to 1350Mhz?

Push it up one unit at a time until it reaches a stable point (Just watch out for heat) . It's better to leave it at 1.2Ghz since I don't think you'll experience any lag at 1.2.
I put it up to 1350Mhz and voltage on the maximum of 5 and so far it's been really smooth without restarting. I'm not too worried about heat as my old Motorola Defy would get to about 60 degrees Celsius and I just played a couple of games and my phone is sitting around 30-40 degrees Celsius
