GPU under clocking - Nexus 4 Q&A, Help & Troubleshooting

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.

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.

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.

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

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

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

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

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.

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

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.

That will make your phone run so slow and crappy... Why have a decent cpu if the plan is to chop it? This defeats the entire purpose of having a 1.5ghz clock speed..

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

It's called 'saving power'.
As long as it doesn't lag and clocks itself up to maximum when required, there's nothing to worry about.
Or you can get some CPU clock app and set it on maximum performance. But don't be surprised if you can boil eggs on it then and the battery dies in 2 hrs :good:

clear the data for tkt and reboot. if you are using tkt, you dont need a powerhal script, since tkt runs it automatically after opening it.
Does Tegra 3 really need overclocked? Having used Tegra 2 I can say that could definitely use a little bump but so far T3 is keeping up with me and I can see a big difference between T2 and T3. Makes me wonder what T4 Wayne has in store.

does it need it.. probably not. do we want to overclock anyways.. yes! btw, its underclocked by default(its rated to 1.5ghz). i use it at 1150mhz as a daily btw.

Slow GPU?

Okay let me start by saying I upgraded from a galaxy s4 (Verizon). So it has the SD 600 and adreno 320. Okay, great. But now I have the SD 800 with adreno 330 GPU and I swear there is so much more lag on the 330. GTA vc is unplayable at max settings (getting about 5-10 fps) where I was getting 20-25 fps on the s4. So my question is why the large performance drop if they have the same resolution display but my g2 supposedly has a faster chip all around?

It could be that things need to be optimized for the higher end Krait 400 cores and Adreno 330. Or maybe it is a driver issue. IDK.
Or, has anyone benched the storage performance on this phone? Maybe it suffers a fatal flaw of slow I/O

I have benched the storage performance and it scores very high. It could very well be an optimization issue, i've played GTA VC on my nexus 10 with no noticeably low framerates... Honestly not sure what the problem is there. Definitely shouldn't be that low.
Do should I exchange it you think?

I am going to try and check some tuning options tonight to see if I can resolve stuttering issues in the games I play. I am wondering if it is simply how LG tuned their governor, since it looks to be using a custom version of OnDemand. The stutter *might* happen when a core turns on or off, or it could be simply how LG tuned their governor for better battery.

[Q] Underclocking for root users Questions and thoughts

Ive been getting smoother results underclocking the G2 at either 1.7 or 1.9 and knock on seems more quick to response, but when I tried video recording the 60 fps isn't smooth when you are clocked at the regular speed.. beware...I ran a benchmark on quadrant standard and got 17,250 constantly so it is underclocked per core... I want to hear your opinion on this and do you plan to underclock or already are. I feel like the ability to be more smooth within the UI helps a lot more now..let me know your thoughts!

I am tending to believe that the regular clock speed is actually overclocked...just like how the galaxy s4 is overclocked 200mhz more than normal...however I could be wrong..
If you really want to see if this odd issue is actually happening download an app called Multicore CPU Control (the only app of its kind that seems to work with the LG G2). I use this to save battery by turning off all but one core, but it allows you full control over all your cores.
Download it, create a profile, and set each core to what you want. I had to save the profile first, then go back in to edit the latter 3 cores' frequencies.
I would suggest setting the min and max to the same and choosing Performance for the governor. Use a different app to set the scheduler.
Be sure to have something like Kernel Tuner to ensure that all your cores are running as you intended. If not, go back into Multicore CPU Control and re-save your profile again.
Would love to hear the results afterwards!
I used Multicore CPU Control.
The only way to set clock to CPU 1,2,3 is let them always active. If I leave dynamic for these cores, they still go up to 2,26 GHZ. I think this the reason why HeXaLox have a little decrement when underclock because it only did for one core.
