the heat from the overclocking plus the slight increase in electricity to the speakers increases the pop which is clipping. In car audio its an insanely bad thing. clipping is when electricity or any other factor creates extra high and overheats the speaker and it burns out. i just figured you may want to know a little more.
@SOAII if the picture looks fine, like no color bleeding or anything then you just need to replace the digitizer. If the actual picture is messed up then you'll need to replace both.
All that effectively matters is the load you plan on putting on your Nexus and for how long. That will determine the Mhz it will run at, and if you run very intensive applications it'll increase speed, and when that happens, just keep the temperature in mind. Try different max speeds and see how stable you are.
I don't own the Nexus 7 so I can't very this myself, but voltage control would also mean that you could undervolt your device too. Provided it's stable, that could allow for a longer battery life. :)
What are the physical risks to running this kernel? And can this be uninstalled as to maintain a valid warranty? How hot can a tablet get before it shuts itself off?
Urrg... This takes a great subject that can really do wonders for a device and herp derps all over it with the most noobish statements and activities. If your actually interested in boosting performance, battery life and stability a custom Kernel under the right setting (not what is shown in this video) is a great way to start. For more info and direction on how to get a custom Kernel on you stock device start reading over at "XDA Developers" it's a great place for mobile device development.
During normal usage, the N7 runs on a single core via 1.2Ghz frequency. When you're doing heavy stuff like video watching, playing high graphic games and etc. It will clock on it's 1.3Ghz frequency.
The performance governor locks the CPU at the set max frequency, so his changes weren't affecting the speed unless he put it back on to interactive or reduced the max frequency
hey i like your video !! i have a question i have bougth my nexus and y want to uptate it to android 4.2 may i can found any problem or somethin have u tried.??? please respond thanx,!!! :D
this comment will be pointless, but forgive me: if you don't really see a difference in game-speed, have to work some hours on the rooting and backup and could have like SOME warranty issues, IF you do something wrong...just to surf the net a bit faster, drain the battery, blow the speakers and heat up the Nexus7 (its getting pretty hot with stock kernel!), what exactly are the upsides?! I had a Nexus for 3 months and can't really see a difference in everyday-speed (not benchmarks) in this vid
Maybe- depends. Setting the frequency itself does no damage what so ever, it is the manual voltage that's the problem. But the Nexus has good heat disposal, so within limits it will do just fine. Thumb rule, OC'ing causes half the lifespan of the processor-but who cares! The Tegra 3 can run for 10 years = 5.
It is actually ~1.2ghz when more than one core is active and only 1.3 when a single core is active. Look up about the tegra t30l on Wikipedia if your interested :)
If you set the lowest speed to the lowest possible and the highest speed to 1500mhz or 1700mhz, is there any common ''overheating'' problem known or will it affect the lifespan?
The whole industry refers to it as "speed" because that's exactly what it is. The frequency of the clock pulses to the CPU is increased, thus speed is a correct term. He simplified a few things but nothing he said is outright wrong. The battery life decreases as the clock speed increases and vice versa. This is because each clock pulse triggers an update of the logic gate states in the CPU, and each update takes some energy to execute.
All the kernal does is unlock the stock kernel to allow overclocking and by overclocking of course you get faster speeds at the cost of battery power which is why the manufactures like to underclock there CPUs so you get more battery and so it does not over heat. But is not as fast installing a custom rom that gives you debloated hash tagged, ziplined, and other tweaks
It might already have it. Setting > About > Android Version. If it isn't 4.2, keep checking your updates. It comes as an over the air, so you don't need to plug it into a PC or anything. Make sure you're on WiFi, and plug in to keep it charged when the update comes.
People who are overclocking a tablet are kind of missing the point. It's a consumer device - pretty much any game or app has been developed to run at the stock speed. There's probably very little point running it faster - it'll just lead to lower battery life, and probably a drastically shorter lifespan due to overheating. There's a reason they don't clock these at 1800mhz at the factory. It's different with PCs of course (I overclock there too) - where you can change the cooling, and boards etc
@pocketnowvideo Why don't you turn off fsync, you well get much better i/o performance and mildly better battery life at some data integrity risk? You can use init.d script to disable fsync. Or I believe you can use Trinity Kernel Toolbox from the android market to turn it of as well as some other i/o tweaks. With the i/o tweaks and 1.8ghz a lot of people are getting 7000 in quadrant. I have turned off fsync on my nexus 7 using a init.d script and it works well :)
may I ask for help on the volume on nexus, it is too quite I can not hear it most of the time, any help would be appreciated, in simple terms please as im old, Thank You George
The kernel is not burning it up. The app he is using to overclock is. The kernel actually is massively improving the processing speed. He really should have not even messed around with a overclock app + new kernel ment to improve speed.
The performance governer sets the CPU to the maximum frequency you specified. Setting the minimum doesn't matter at that point. Only when you go into another governer will the minimum matter.
you got 5400+ score in quadrent with this kernel running @ 1.8GHz , I've seen the N7 get a 7100+ in the same benchmark using the trinity kernel running @ 1.6GHz , you do the math
I have the nexus 7 2 and I don't have to do any kernals or rooting to get it smooth, it IS smooth. It's running on a snap dragon s4 pro with adreno 320 gpu with 2gbs of ram. Amazing device. It tears through any game I throw at it, also it has a 1080p scree
1) Benchmarks do not always represent the speed your device has during normal usage 2) Believe me, Google know what they are doing. They absolutely optimised the Kernel to provide you with the perfect balance between battery life and performance. 3) If you choose a 'performance' governor, its gonna run at the max speed all the time -> could light up a nice fire You can only make it worse, believe me ;-) These engineers are professionals, not some geeks who modify it at 3 o clock in the morning
Set CPU overclocking on my N7 didn't do anything but obliterate my battery life (using the on demand governor). I didn't notice any extra speed or anything. It's already super smooth with no lag so I uninstalled it. It may benchmark faster but in real world use, I noticed no tangible difference. On my Mytouch4G though... HUUUUUGE difference.
I overclocked my 1Ghz Qualcomm Phone to 1.8Ghz. The performance boost is nice, but the REAL benefit is better battery life. You can chose a good governor and have the device clock down to 200mhz for many things (mp3s etc)
Games like nova 3 are laggy and need the extra boost of a custom kernel mine has the GPU over clocked which males a big difference but it does hurt battery life
Well why get a lower battery life+heat issues and speaker issues when the tablet is already fast enough to do anything lag-free, play games, watch movies etc....
Is it not fast enough already?? Lol geez speed demons are never satisfied I see. I stopped seeing the point of rooting and overclocking like 6 Android phones ago lol.
I learned more from the comments than from the video. That's not so common. Thanks internet.

i think the screen and digitizer are molded together, so it would require to change both. take a look at xda-developers forums
when he makes a long pause, I shiver

Those pops you here are the noise of the processor being amplified didn't think it would be that bad on a mobile device as opposed to a PC
hey i like your video !!
i have a question i have bougth my nexus and y want to uptate it to android 4.2
may i can found any problem or somethin have u tried.???
please respond
thanx,!!! :D
why is the vid quality like it was taken in the 80's?
Running your nexus 7 on afterburn...
So.... if this was on a S3 what would be?
speed of sound?
this comment will be pointless, but forgive me:

I had a Nexus for 3 months and can't really see a difference in everyday-speed (not benchmarks) in this vid
Maybe a dumb question but what does the kernel do differently than if I just rooted my Nexus 7 and downloaded setcpu?
Do you know how to do that? I want to run Paranoid Android and Elite Kernel if that's possible.
Maybe- depends. Setting the frequency itself does no damage what so ever, it is the manual voltage that's the problem. But the Nexus has good heat disposal, so within limits it will do just fine.
Thumb rule, OC'ing causes half the lifespan of the processor-but who cares! The Tegra 3 can run for 10 years = 5.
It is actually ~1.2ghz when more than one core is active and only 1.3 when a single core is active. Look up about the tegra t30l on Wikipedia if your interested :)
From Wikipedia: 1.2 GHz quad-core ARM Cortex-A9 (up to 1.3 GHz in single-core mode).
if you want the best battery and performance check out the linaro kernel (bluetooth dosen't work on it though)
If you set the lowest speed to the lowest possible and the highest speed to 1500mhz or 1700mhz, is there any common ''overheating'' problem known or will it affect the lifespan?
what about the nexus 10 which HAS the best resolution at 2560 by 1600 pixels?

Have you used it any time in the last like, 4 months? It works incredibly.
I really didn't think it chrome was that laggy or choppy in the first place, nonetheless cool to know I could speed things up if I wanted to.
just so you know you do not have to set the minimum at 1800 Mhz when you use the performance governer, it keeps it at the max only.
setcpu is not free? or it was free but not now?
I have the Motley kernel running with 4.3 android and it's a lot smoother and I can still over clock to 1.6ghz which is not bad.
the final amt inc shipping and tax ?
Will this Kernel save my battery draining and give me better performance??
It might already have it. Setting > About > Android Version.
If it isn't 4.2, keep checking your updates. It comes as an over the air, so you don't need to plug it into a PC or anything. Make sure you're on WiFi, and plug in to keep it charged when the update comes.

With the performance governor the minimum frequency is ignored, it stays at max... no need to set that

Anyone know what portable hard drives roughly 250gb work with the nexus media importer?
may I ask for help on the volume on nexus, it is too quite I can not hear it most of the time, any help would be appreciated, in simple terms please as im old,
Thank You

make sure you dont put the governor to performance, its bad for the device and batter
The kernel is not burning it up. The app he is using to overclock is. The kernel actually is massively improving the processing speed. He really should have not even messed around with a overclock app + new kernel ment to improve speed.
The performance governer sets the CPU to the maximum frequency you specified. Setting the minimum doesn't matter at that point. Only when you go into another governer will the minimum matter.
I run M-Kernel on mine and it's BEAST, great for gaming, browsing, and battery life.
Is it for asus nexus 7
Dude the Nexus does not lag stock he is crazy
How much is battery life affected by this?
What is the safest, more stable kernel/rom that speeds up my tablet?
would doing this affect the lifespan?
does it damage the processor??
Performance governor makes your device lock at the highest Mhz in setCPU, performance governor is only for benchmarking and really heavy gaming! :-P
does this app really work. I think im just going to try the motley kernel? yeah.
Cars, processors, fantasy sports leagues, Android especially. Us men just loooove pushing things beyond the norm.
you got 5400+ score in quadrent with this kernel running @ 1.8GHz , I've seen the N7 get a 7100+ in the same benchmark using the trinity kernel running @ 1.6GHz , you do the math
I checked the Play Store, SetCPU doesn't appear to be free...
i think maybe chrome is forced to use limited resource
unlike firefox or stock android
maybe thats why the lower performance on higher-end phones?
yeh, you can. I think its stock if you buy it now
I prefer the Lean Kernel, personally. No frills, no bull. It's fast, clocked to 1.5GHz. Pretty nice.
if u root or install custom kernel or rom u wont get updates from google unless u go back to stock rom
no one should blame the nexus 7 for browser experience using chrome but if u were to install any other browser it u will see a huge difference
So buy one?

How did you disable the vsync
1) Benchmarks do not always represent the speed your device has during normal usage

On my Mytouch4G though... HUUUUUGE difference.
Would it not overheat the cpu? D:
whoa wait.... is that a classic style xbox 360 without Red ring of death????? I thought those were unheard of.
Anyone know how to root Samsung infuse 4g with gingerbread 2.3.6 AT&T... I can't figure it out
wouldn't it be better to just install aosp browser?
You could also install ubuntu on your nexus 7 and it performs great.
I can't wait getting one of these amazing tablets for my birthday
Running his 2ghz kernel now, and its just dumb fast. Haven't hit 8000 in quadrant yet, but definitely in the 7500 range
what about battery live ?
What is the normal state of nexus 7
Love this stuff. I gave the video an 'afterburner' thumbs up.
where can we get this?
Can I run this kernel AND a ROM on my Nexus 7?
I overclocked my 1Ghz Qualcomm Phone to 1.8Ghz.
The performance boost is nice, but the REAL benefit is better battery life.
You can chose a good governor and have the device clock down to 200mhz for many things (mp3s etc)
This video is the EXACT reason why your grandma doesn't have an Android device, or at least not intentionally.
he killed me at 4:47 at the "and how smoooooth" lol
Is it gets as hot as iPad 3 ;)
Fail :D Motley Kernel no voltage change, ondemand 51/1300mhz.
Quadrant is always around 5650 points ^^
it seem like i can do backup with ROM Toolbox Pro, and it use TeamWin recovery software.
Anyone knows if once i root my samsung galaxy s 3 there can be a posibility to unroot it?
Performance governor just locks the speed at the max clock speed. It will wreck your battery life.
Games like nova 3 are laggy and need the extra boost of a custom kernel mine has the GPU over clocked which males a big difference but it does hurt battery life
how to overclock N7 2012 on android 5.1.1?
Do i have to wipe my device when i install a different kernel?
Some people say, that for their Nexus, it's a little bit unstable. For my Nexus, it's a little bit unstable.
Tegra 3 or s4?
how come nexus 7 is 1.8ghz ?
My Samsung galaxy note2 at stock speed kinda beats the nexus 7 in any aspect. now im going to OC, to 2,2Ghz and see what numbers i get
0:30 Thought he was going to say "It's like running your Nexus 7 on... acid."
Is this compatible with android 4.2.2 Smooth Rom v5
Well why get a lower battery life+heat issues and speaker issues when the tablet is already fast enough to do anything lag-free, play games, watch movies etc....
Is it not fast enough already?? Lol geez speed demons are never satisfied I see. I stopped seeing the point of rooting and overclocking like 6 Android phones ago lol.
which file do I flash?
Hay can you give a link to having 4.1.1 on my nexus 7 pls
Will this work on 4.2?
Emulators are cpu intensive even on older games. If you want to play any DS games on with good fps you are going to need to go that high.
And if the min and max are same don't need performance and you should never select set on boot with it set that high smh who is this guy
Agree!
Very great kernel, tried just now.
