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.
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 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.
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. :)
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
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.
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 :)
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
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
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
@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.
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.
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.
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.
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
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
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.
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?
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....
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
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)
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.
Firefox is a memory leaking mess of code and resource hog, I don't think it would be better on a phone or tablet if it can slow down my gaming computer.
FF has now been compromised by George Soros and Co....STAY AWAY FROM IT....unless of course ya don't mind FF serendipitously rooting around and gathering your info
For me the stock kernel is fast enough because i dont even experience lag on games and chrome and for me i dont want to burn my nexus 7 because of the heat it produces when that kernel is installed but thanks for the video dude
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?
I have a stock N7 32gb. never any problems or lags. dont mess with it. just enjoy the greatest hand held tablet ever!!. plus I need it to last on its battery. so just leave it alone man
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.
That's like asking "Do I have to wipe my ass whenever I take a shite" lol However, if your ass was an android device, then the answer is no. Type into google to get full page: Go to Wipe and do - Wipe cache, Wipe Dalvik Cache and Wipe ALL data/factory reset. If flashing just a new kernel, don't do Wipe ALL data/factory reset as your current settings will go away. ( Remember to take a Nandroid backup before you do wipe. If not, see part 2 for it.)
Nope, not gonna do it. I remember the last time I overclocked something, it was my original Motorola Droid at 1.0 GHz. I was using it, it was running fine, and then suddenly it began to heat up a lot. The phone then shut itself off. Upon reboot, the M logo was all glitchy and off to the side. When the phone was tried to be repaired, I found out that the processor itself was completely fried and I should be surprised that it would even boot. All I could load was bootloader, which is on the ROM.
when he makes a long pause, I shiver

I learned more from the comments than from the video. That's not so common. Thanks internet.
Love this stuff. I gave the video an 'afterburner' thumbs up.
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
From Wikipedia: 1.2 GHz quad-core ARM Cortex-A9 (up to 1.3 GHz in single-core mode).
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.
I run M-Kernel on mine and it's BEAST, great for gaming, browsing, and battery life.
Is it for asus nexus 7

Cars, processors, fantasy sports leagues, Android especially. Us men just loooove pushing things beyond the norm.

why is the vid quality like it was taken in the 80's?

But is not as fast installing a custom rom that gives you debloated hash tagged, ziplined, and other tweaks
I can't wait getting one of these amazing tablets for my birthday
I prefer the Lean Kernel, personally. No frills, no bull. It's fast, clocked to 1.5GHz. Pretty nice.
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.
@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.
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
Dude the Nexus does not lag stock he is crazy
0:30 Thought he was going to say "It's like running your Nexus 7 on... acid."
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.
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.
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 think the screen and digitizer are molded together, so it would require to change both. take a look at xda-developers forums
yeh, you can. I think its stock if you buy it now
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
Some people say, that for their Nexus, it's a little bit unstable. For my Nexus, it's a little bit unstable.
4:47 HOW SMOOOOOOVVVVE
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.

Performance governor makes your device lock at the highest Mhz in setCPU, performance governor is only for benchmarking and really heavy gaming! :-P
no one complains that windows phones make you use internet explorer and apple makes you use safari
heats up very fast and battery is pretty much fucked up
better sell it then....how much?...lolz
Running his 2ghz kernel now, and its just dumb fast. Haven't hit 8000 in quadrant yet, but definitely in the 7500 range
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?
Have you used it any time in the last like, 4 months? It works incredibly.
Performance governor just locks the speed at the max clock speed. It will wreck your 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....
i think he means using wine to run full windows apps
Opera Mobile for life! Special place in my heart for that browser.
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
HOLY SHITT!!!!!! i'm so gonna flash this kernel!!!!!
You could also install ubuntu on your nexus 7 and it performs great.
This video is the EXACT reason why your grandma doesn't have an Android device, or at least not intentionally.
Very great kernel, tried just now.
This 1080p vid is shockingly low-quality
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)
Fail :D Motley Kernel no voltage change, ondemand 51/1300mhz.
Quadrant is always around 5650 points ^^
I DID IT AND MY NEXUS CAUGHT ON FIRE
were you able to fry egg?
I spy a Galaxy Tab 2 7.0 on the table in the background in the beginning of the video.
Will this Kernel save my battery draining and give me better performance??
because the stock kernel won't allow overclocking.
if you want the best battery and performance check out the linaro kernel (bluetooth dosen't work on it though)
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 thought the Nexus 7 was 1.3GHz?
Firefox is a memory leaking mess of code and resource hog, I don't think it would be better on a phone or tablet if it can slow down my gaming computer.
FF has now been compromised by George Soros and Co....STAY AWAY FROM IT....unless of course ya don't mind FF
serendipitously rooting around and gathering your info
whoa wait.... is that a classic style xbox 360 without Red ring of death????? I thought those were unheard of.
overclocking
watch the clock as battery goes bust
make sure you dont put the governor to performance, its bad for the device and batter
if u root or install custom kernel or rom u wont get updates from google unless u go back to stock rom
That guy in the video was on To Catch a Predator. Omg.
What is the safest, more stable kernel/rom that speeds up my tablet?
I love Burn Notice!
Bruce Campbell is such a stud, he makes the show! =)
"not quite twice as fast but a good bit faster" ... well you didnt quite double the core clock but you did make it a good bit faster .....
setcpu is not free? or it was free but not now?
So buy one?
With the performance governor the minimum frequency is ignored, it stays at max... no need to set that
It was pretty pointless setting the governor as performance and then clocking the maximum to 1.8, and the minimum to 1.8
For me the stock kernel is fast enough because i dont even experience lag on games and chrome and for me i dont want to burn my nexus 7 because of the heat it produces when that kernel is installed but thanks for the video dude
The one you have isnt this one Model#: RB-RRASUNEX7-32G-K
wait for the the nexus 7 2 coming in august.
Running your nexus 7 on afterburn...
So.... if this was on a S3 what would be?
speed of sound?
Not relatively fast. It's high-end fast, as in, one of the fastest, with potential to be THE fastest android tablet on the market.
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?
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.
I checked the Play Store, SetCPU doesn't appear to be free...
wtf, how is using the chrome browser a bad thing?!
I have a stock N7 32gb. never any problems or lags. dont mess with it. just enjoy the greatest hand held tablet ever!!. plus I need it to last on its battery. so just leave it alone man
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?
What is the normal state of nexus 7
people who hate long battery life and almost frying their tablet
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.

Ask CNET why they didn't include it, maybe cause IT JUST CAME OUT.
Who the heck needs to overclock to 1.8 GHz?
Same here and I've had it since they first came out
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!
Nope, not gonna do it. I remember the last time I overclocked something, it was my original Motorola Droid at 1.0 GHz. I was using it, it was running fine, and then suddenly it began to heat up a lot. The phone then shut itself off. Upon reboot, the M logo was all glitchy and off to the side. When the phone was tried to be repaired, I found out that the processor itself was completely fried and I should be surprised that it would even boot. All I could load was bootloader, which is on the ROM.
Maybe a dumb question but what does the kernel do differently than if I just rooted my Nexus 7 and downloaded setcpu?
...and that's why Android Devs are pissed when they aren't getting paid.
1:09 it's not a phone.. it's a tablet
One does not simply overclock a Nexus 7 to 1.8GHz..
