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
Corey
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.

Nexus 7 100° too hot?

Sounds like you can boil water with your Nexus 7. IDK about the N7, but for laptops, you don't want it that high. 80C is the hottest my laptop gets when I overclock it.

Mine is in 100°F. It is about 40-45°C

you are looking at the battery temperature(100F). the human body averages 98.6 degrees, higher with a fever. do you really think its too hot, lol. if your cpu temp hits 100C, your devices safety would kick in and shutdown/reboot the device. and there arent many cpu temp apps . most likely yourre looking at your battery temp. btw, 100C is 212F(the boiling point of water).

Being a tech nerd has the great side effect of teaching you the metric system by proxy. :laugh:

You have to do something to reduce the temperature. For me its quite over temperature

My nexus 7 gets too about 50°C (122F) while gaming on a regular basis.

That's way too hot... Your chip shouldn't be able to boil water. Lol. Depending on what kernel you use there may or may not be thermal throttling. But in any case, I would caution to say that's not good for your device.

the op was talking about 100F, not 100C. at 100C is the nexus 7 automatic shutdown temp. 100F is slightly warmer than body temp(98.6F).

How hot does your device gets?

I have been asking this in few threads lately and no one yet to answer. I installed system tuner to check the cpu temperatures and seems to be a little high compare to other devices that I owned. With regular use the temps seems to be around 45-50C and with heavy use and gaming it would go up to 60C. The device also feels a little warm around the camera area. I would appreciate if someone could check their temps. Thanks.

Haven't measured, but mine gets SUPER hot sometimes. Usually when playing games, or like last night, I was on skype for ~4 hours. It get's hot, but I would expect it or any device to get hot when doing that type of stuff.

I don't own one but those temps are right in line with the average desktop pc. I think once temps hit about 65-70C under heavy load, then there is reason for concern.

Mine got up to something like 42 degrees C yesterday while browsing. Got the temperature readout using Cool Tool. Heat was mainly around the top / camera area where I assume the antenna is.

38° C max and that's when i m charging and using the phone.

42 is not hot. Its warm. To qualify as hit it has to reach at least 50.

How do I disable Touch Booster?

Hey guys, touch booster is really annoying on this phone. It pushes the phone to 1.06GHz everytime I touch it, and is starting to bug me.
Is there anyway to keep it scaling up properly?

I'm no expert at this stuff, but isn't this fast jump in CPU clock what pretty much makes Project Butter possible?

If I understand right (and I probably don't), I think this might have to do with with governor in-use. If your rooted; try using a different governor and then touching the screen.

Great, so now people are complaining about Project Butter's features... ok

How exactly does something like this bug you?

People are getting way too picky with this phone now. Relax, its a phone guys

Sent from my Nexus 4 using xda premium

The CPU goes up when you touch it so it can be responsive and quick to your inputs. How is this so annoying?
If you root it you can lower the max or change the governor buy chances are you will lose much of your responsiveness.
I understand that it is good for us to discuss issues and problems but some of the things I am seeing here are just really nit picking and complaining about things that are not bad at all. We are a spoiled society of humans, some more than others i guess.

Get some CPU control app and change the minimum frequency from 1GHz to 384MHz.

Under clocking will save battery in most cases but ot will also make your phone sluggish and slow depending on how much.

You have no idea what you are talking about.
Check the meaning of "MINIMUM CPU FREQUENCY".
P.S. O and btw I'm changed it to 384MHz on my Nexus 4. AND........wait for it........my nexus 4 is not slow and crappy........woo mind blown!

What I find interesting is on the nexus 4 the governor is on demand , and the scaling range is 0mhz- 1026mhz ( you can check using CPU spy +)
However on the nexus 10 , the governor is interactive and the scaling range is 0mhz -200mhz
I wonder why that is

I'm using no-frills and the default is ondemand, scaling from 1GHz to 1.5GHz.
What I changed is only the minimum frequency from 1GHz to 384MHz. Nothing more.

Nexus 10 is a dual core tablet, not a phone. Check your PC some time or laptop. They scale totally differently than a phone does.

GPU under clocking

UI still runs super smooth at 128MHz, so will setting it to this have any major positive effect on battery life? If not playing games I'm guessing u won't really need all that GPU power.
Sent from my Nexus 4 using xda app-developers app

Well, in technical terms it *should* give you better battery life because it's reducing stress on a main hardware component so it doesn't have to work as hard (the harder it works, the more battery it takes). Same thing with the screen; the lower the brightness, the better the battery.

Wouldn't it have to work harder for longer because it can't do anything as fast? It isn't like if you set the GPU clock to 487mhz it runs at 487mhz all the time, so ramping up to 487mhz would allow it to finish whatever it is doing faster wouldn't it?

Then wouldn't it be the same with the CPU? When I answered I was thinking like how a CPU would work. I understand your thinking though.
Sent from my Nexus 4 using xda premium

Well I would like to add that the 540 sgx can power the 720P in the Galaxy Nexus... That dino is significantly weaker than the Adreno 320 even over clocked. I run 128 only and it works fine for games and even HD videos(YouTube). To confirm I tried Most wanted, dead trigger, temple run, riptide,etc and there weren't any issues(also toggled vSync). And if you use benchmarks like Epic cidel or antutu you'll see the frames are still pretty high.
So I'll say that 128 or even 200mhz is sufficient for this GPU and most purposes. However a good I/o scheduler and governor are still recommended.
Sent from my Nexus 4 using xda app-developers app

I think another advantage if it runs what you want at a good frame rate is less heat.
