What is a safe level to over clock?

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance
Cheers

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?

Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic

IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.

I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again
Cheers

Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?

I go to 1.6 but use the Trinity App to go back to stock when OC not needed
Sent from my GT-I9300 using xda app-developers app

I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.

Why does this thing lock up all the time?

This device is blazing fast most of the time, but it will inexplicably lock up, completely, for a few minutes at a time for seemingly no reason. Right now it's frozen on a youtube video and I can't turn it off or use the screen. The device is also unusable really when installing apps, and will lag heavily in Google Now sometimes.
Is this just me? Or 4.2.1?

Just you. My N7 is still operating at warp speed and doesn't lock up..

Are you stock? If so I heard people saying turning off the sync for currents will help, for Google now lag I feel its performs better if you turn off the hot word in setting. But with that you can't say Google and start voice search
Sent from my Nexus 7 using Tapatalk 2

I'm stock 4.2.1 and don't have those issues. I do have currents (and various other apps) disabled, so like previous response said try that. Otherwise maybe go with a factory reset.
When my gnex updated to 4.2 it's performance suffered until I factory reset, now it's been much better.
Sent from my Galaxy Nexus using xda premium

My best guess would be you have installed an app that is not compatible with 4.2.
How about posting a list of what you have installed, if you use multi-user, and if you are stock (not rooted), and we can give comments.

I agree. I'm running PA and rock solid. I was also rock solid on stock.
I've never had it lock up. I flashed a Trinity kernel once that caused sleep of death... but it was a known issue.

I have a pretty decent amount of apps installed. I'll post them in a minute, but no, I'm not multi-user, and I'm stock. I'll root and put a new rom on this thing if it's worth it, I figured it'd be fine the way it came.

btw, here are my androbench results. Are these slow?

These are what I disable.

thanks, I'll try disabling those.

Over 100 apps in total, my andronbench write speed is clearly an error so just compare read and app open macros.
My apps open much faster than yours, which I'd put down to PA ROM and kernel. Maybe your write speed is a bit slow?
Can you download "forever gone" from market and try a full fill and delete? Apparently helps reset the memory controller to improve performance.

Should I disable or enable FSYNC?

I know this is a noob question but please enlighten me. Because I'm so confused on how to perfectly run jays buttery goodness. I'm using SmoothRom 4.2.1 and M-Kernel @1.4ghz on a performance governor. Thanks! Any recommendation is totally appreciated.

It really matters on which you want more... performance at the expense of possible data corruption, or data integrity at the expense of some performance.

If you get a database corruption, what is the likelihood that you can recover from that if you have a nandroid or adb image?
Also, what if you do that apps2sd mod, do you still need to disable fsync?

Epsxe/Fpse Battery drain

So actually I am a big fan of ps one games and I can't resist to not play ps1 games on my phone.
Well I am worrying about there battery drain here.
After playing a game on my epsxe and fpse(about 35 minutes) I go from 100% down to 69%
Is it normal? or not?
(also my phone heats up after this amount of time)

Most likely you need to change CPU settings, including voltage.

I am on stock android(rooted)
Can you recommend me a good Rom-Kernel combo ?
Cause this is my first android experince, and I am not sure what the best rom is for a beginner like me is .
I also do not want to damage my phone by tweeking with the cpu and voltage settings.
Should I wait maybe for stable roms? Cause I see alot of nightlies roms.
Also I am not familiar with the term "milestone rom"
Thanks in advance.

Any of the custom kernels should last a bit longer than stock. I use IntersectRaven's kernel. I have fpse but haven't gotten around to putting any iso's on here yet so I'm sorry I can't give any report. You could also try lowering the brightness while you play, and turning off data or just enabling airplane mode if you don't mind not being able top receive calls or texts while you play.

You can stick with stock ROM rooted but you can under clock it. The emulator doesn't need a lot of power, I use yo use it on my 600mhz phone so it should be fine with the nexus. Also stock rooted is the most stable.

Or keep the phone plugged charging while playing, this phone is a battery hog, i mean am not trying to generalize, but seems like some people try to multitask all day long on a mobile device with no removable battery, i mean really, think about a gadget trying to process console games, web, content, gps, screen activity, all at the same time, come on people at the end this is a phone not an alienwarelike or multitasking wireless gaming console

Okitche very
Thanks for the replies guys !
Should I use SetCpu in order to under clock it?
Also I heard many positive things about the franco kernel, is it worth giving a shot?

I haven't tried it personally but, you should still give it a shot. And setcpu is fine.

Most custom kernels lag more than the stock kernel.
If you want to go the custom kernel route for (at the moment) better battery life, go either CyanogenMod(the one included in their ROM) or Franco.

Battery Save app

For you What is best app for Battery saving? Sorry for my English
Sent from my GT-N7100 using XDA Premium 4 mobile app

Power saving mode of n2 with greenify. If you want best battery be on 4.1.2 rom with perseus kernel. Unmatched combo

greenify
Im using greenify too.. it works with 4.4.2 too..

It's worth trying xposed receiver stop and boot manager with greenify as well

Greenify is great
Sent from my GT-N7100 using XDA Premium 4 mobile app

my theory is to don't use power saving apps, I use the built -in power saver, automatic screen brightness, when I exit an app or game I remove it from the recent list, if im in a place with no signal I turn airplane mode on. If I dont need internet I turn off the wifi/data.

power saving mode is great always.. give a try to DU battery saver if u are not rooted. It works pretty well for. Add the cleaner widgte to your screen which helps clearing the RAM with a tap..

Greenify Donation. Its worth it. I don't care what ROM it is battery life is great as long as I wipe internal SD before flash

Hey,
are there any proofs that Greenify increases battery life? Any benchamarks? Comparisions?
Or just illusion?
Like apps to increasing performance, they are ruining it. (i will reccomend here LagFix app

Why don't you try using it and see for yourself. There's nothing better than doing it for yourself rather than relying on somebody else, no?
Benchmark you are referring to is some what, stupid. I am pertaining to a benchmark which elevates the standard of battery saving or performance enhancing.

Greenify should share theirs results to public, if they saying it will increase your battery then prove it! Show me the results. Im that kind of person.

One option is to install a good kernel for your ROM and configures it to consume little energy (UV)

Undervolting is still controversial. I used to do the same but also tried stock settings and have even or better battery life.

greenify is the best battery saving app plus you need to remove unwanted apps cz they may be eating battery..mobile data eats battery no one can help you there it's always better to use wifi when it's available..

First of all I would recommend to change the kernel. If you're on version 4.3 or lower Pegasus Kernel provides the best ratio between performance and battery drain.
It's much better than using a task killer.
I tried both, but any task killer isn't quite comfortable, because it closes tasks you may need. And also white listing isn't always an option. Nevertheless you'll have performance lags as soon as the cache is cleaned. Any app has to reload its processes anew.
