temps

thanks for the guide. I've read through all 11 pages. but couldn't find what I was looking for.

what is the maximum temperatures (celcius) these chips can go too? and do they throttle?

what is a reasonable safe temp at full load?

anyway of measuring GPU temp? IF so same questions above for GPU.

thanks
[Galaxy S III General] bala_gamer:
CPU will be throttled down when it reaches 79c or 80c. Afaik there is no way to monitor gpu temp

[Galaxy S III General] GrimPivo:
Does undervoltage affects UI and games speed, or not?

With default clocks, ofcourse.
[Galaxy S III General] stefankorun:
It shouldn't, the clock speed of the CPU is the same, undervolting might cause only instability (restarts) if the CPU need more voltage to do its job.
[Galaxy S III General] AbuYahya:
thanks but the next question would be is this sort of temp say (Tmax -10 =) 70C which is then dissipated heat safe for other components (such as the screen)?
[Galaxy S III General] bala_gamer:
afaik there is no documented values for dissipated heat on components. i dont think the heat dissipation will reach other components that easily.
[Galaxy S III General] Striatum_bdr:
Hi

Do you have objective data concerning battery life comparing stock voltage and undervolting?

We had long discussions for my previous phone (p990 LG) and many devs thought that uv is quite useless and can lead only to fc and instability.
[Galaxy S III General] bala_gamer:
extreme undervolting will always cause instability.

undervolting will not make your battery life all better , you may note an additional battery life of say 1 to 2 hours dpending on your usage. but when combined with overclocking it reduces the additional heat generated by overclocking and yet improve your battery life by say 1 hour.
[Galaxy S III General] deom2i:
Yeah! Tamil :) hahaha.

Will we be able to run 1.6ghz as note 2, or its a different chip from ours?
[Galaxy S III General] bala_gamer:
Afaik same chips but with better yields. Am running at 1.6ghz without any problems :beer:

《swagged from aokp》
[Galaxy S III General] deom2i:
What voltage have you set at 1.6hz. Im currently at 1400mv.
[Galaxy S III General] bala_gamer:
using 1275mv.. your mileage may vary ;)
[Galaxy S III General] ikarus17:
Thanks for the awesome guide!!!!

:good:

HI bala, Thanks for this wonderful guide, I tried your setting and it was awesome i ran it for 15 mins and no error at all plus my phone is not that hot unlike before. would you know what is the stock mv for CPU and GPU? Many thanks and keep up the good work
[Galaxy S III General] bala_gamer:
stock voltages are already there in the 1st post :)
[Galaxy S III General] baileyjr:
A quick question about instability when undervolting.

I can run a stability test for 20+ min without problems or errors, however I have been experiencing some random device lockups that require a reboot. These usually happen when the device has been left unattended for a few hours.

Could this be down to the undervolting, or would undervolting problems come to light when running a stability test?

Of course thats just one factor given Im running a developer release of Jelly Bean and that the new Kernel has just come out of beta.

On a positive I can now push my GPU to 700 with the latest 1.6.3 kernel release and I get a score of just over 50 in ES2 Taiji.

I'm gutted there is no way to monitor the GPU temp, but it should throttle down if it gets to hot?
[Galaxy S III General] ikarus17:
Hi bala..

my phone is idle i get a drain of 1% per 1hr and 30mins ( roughly estimation) is there any prob with the setting that i made?below is the screenshot from setcpu and stweak. Thanks bala.
[Galaxy S III General] bala_gamer:
@baileyjr

Instability will generally show up when the device is stressed to the maximum. Getting lockups when the mobile is idle might be related to some other parameters

@ikarus

Those settings are not going to do anything with your battery life. Find and resolve your wakelocks

[Galaxy S III General] kachrukamble:
With siyah 1.6.5 I undervolted GPU to-50, ran stress test twice, it completed without error.

phone was running good too but Not in Games. Example Temple Run. it was out of my control.

Now I reduced Gpu Votage to -25 for each and all working good.

Whats wrong with -50??
[Galaxy S III General] S1N1ST3R:
Is anyone else unstable at 1.6GHz? Doesn't crash when its stressed @ 1.6 but during idle or some mundane task.
[Galaxy S III General] AbuYahya:
I have some interesting finds.

Using Ronen Rom v1 & Perseus Kernel 23.4 & While unplugged but in a full leather like case.

I can run at 1.8Ghz at 1400mV but temps are high in 70c. throttles at 75c and turns the other cores off so only a single core at 1.8Ghz running while other 3 offline.

Even 1.6Ghz at 1250mV throttles at 68C switching 3 cores off and only CPU0 is running.

Testing 1.3 Ghz and 1.4 Ghz both of them throttle at stock voltages when exceeding 63-64C.

1.4Ghz @ 1175mV eventually throttles too.

1.3Ghz @ 1125mV and 1150mV were ok but raising voltage made it hit 64C at which point in throttles.

Without case at 1.4Ghz @ 1275mV which is less than stock, throttles at 68C.

On stock kernal. Throttles when exceeds 64C but throttling behaviour is different it keeps all four cores online but cuts freq of all to 800Mhz. Also the throttle is much shorter in duration.

Can anyone confirm this?

Throttling at stock is ridiculous.

edit

ICS stock BLG8. Throttles when exceeds 64C by reducing all four cores to 800Mhz.

Again throttling at stock is ridiculous!
[Galaxy S III General] bala_gamer:
@anuyaha

u sure talking about cpu temperature? ;) the cpu throttle down temp is 79 C and i have tested it in the past, may the newer custom kernels might have changed it, bu im not sure about this
[Galaxy S III General] AbuYahya:
its Definitely cpu temp according to the app "system tuner" which shows all 4 cpu's freq and total temp.

Throttling temp appears to be different for different frequencies.

The problem is if you use an app that doesn't tell each CPU core frequency then if it throttles by switching 3 cores offline then you may not realise.
[Galaxy S III General] AbuYahya:
Throttled 6 tines in 5 mins

What sort of temps do you get at full load for 5mins.

EDIT

it the pegasusq governer causing this phenomenon which disappears on changing to performance governor.
[Galaxy S III General] baileyjr:
Bala can you confirm that the GPU also has a throttling mechanism built in so that I shouldn't fry if I'm running at 700 :D
[Galaxy S III General] bala_gamer:
am sure that every chip has its own safety mechanism these days, so it should be there somewhere. the voltages used for 700mhz are safe values afaik, so mobile getting very hot in your hand should be your first alarm ;)
[Galaxy S III General] baileyjr:
I've actually dropped the GPU back to 600mhz now. Benchmarks were fine but under extended use in games like RR2 I was getting some screen tearing.
[Galaxy S III General] dark_polok:
Hello.

I'm on Nimphetamin 1.2.1 kernel. Can you please tell me which app will allow me to overclock/undervolt GPU?
[Galaxy S III General] bala_gamer:
You sure using the right voltage?

Afaik it can be done only via scripts. Better ask this question in the kernel thread mate.

Hi bala_gamer,

Maybe you can update the OP with this: http://xdaforums.com/showpost.php?p=32454692&postcount=7965.

Mainly the flashables zip are for Siyah kernel but some settings can be applied to other kernel...

Your topic is mainly for Siyah kernel but it also serves for other kernel, just an idea..., there was good parameters to use.

:)
[Galaxy S III General] bala_gamer:
@viking

Thanks for the suggestion mate, you sure it would be helpful for other kernel? May be perseus will support it. But what about others? It would be better to test it before suggesting to others. What you say? :)

《swagged from aokp》
[Galaxy S III General] :
Re,

I just watched yet the kernels... Yep it seems besides Siyah kernel and Perseus kernel (but with no compatibility with ExTweaks/STweaks)...

The flashables zip will work only with Siyah kernel for sure, but inside the zip's some users can take some settings for another kernel (UV or governor control for example), but right exept for the 2 kernel mentioned above...

For GalaXsih kernel: governor control, UV maybe, all the rest I don't know.

For Phenomenal kernel: governor control and... I don't know (for sure no UV/OC).

For N.E.A.K. kernel: governor control, all the rest I don't know... own app.

For franco.Kernel: own app (no OC)...

In all the case governor settings can be useful, users need to see exactly the different "features" of their kernel (UV, OC CPU/GPU)... :rolleyes:

Just a quick tour, and I don't know the compatibility with ExTweaks/Stweaks for the others (I mean the path for the different settings, the symlink (?))...

Conclusion: you're right, just Siyah kernel can fully benefit of these settings (fully flashables zip) and only some others kernel can benefit from some settings (opening the zip, extracting the file, open it with notepad for see the settings).

Ouch! Hard! :D :p :D

PS: sorry if I'm wrong about some kernel.

UV GPU already enough?

bala_gamer,

I read a viewpoint from suntzu123 's post in http://xdaforums.com/showthread.php?t=1709686&page=302 , that "... There is only one element that you can save a lot of power. GPU! I don't know how to lower clock's here."

May I have your sharing on whether UV GPU is a more important factor in power saving? Do UV CPU / lowering CPUs still important?

As newbies still on icm stock with siyah 1.37b looking for battery saving config, hope to read more on various xda posts for bettering understanding UV. Thanks! (also thx to suntzu123's post there)
[Galaxy S III General] bala_gamer:
UV cpu or gpu wont have a major effect in battery life , you may get 2 to 3 hours of additional life. Your device will genrate less heat which is a major advantage. Yo can also downclock cpu/gpu to get some more battery life. Just lower the max clock values. I generally dont care much about battery life , my overclocked settings is there in my sig :). If you figure out a proper way of identifying wakelocks you can always get a minimum of one day battery life for sure :)

Thanks for the info, I am new to all of this, does over clocking reduce the battery?

Not by a big margin, undervolting along with Oc is much better

《swagged from aokp》
[Galaxy S III General] daniel84cs:
My S3 is very stable up to 1704 MHz and -125 mv of Undervolt. The GPU is 700MHz and up stable -100mv.
[Galaxy S III General] danielsf:
Just messing about and I decided to test how much undervolting may help with heat production. So I quickly came up with this rudimentary test that anyone can do. I used this cpu stability app and selected stability test to run in the back ground, all cores are now running at full load at 1.4ghz and stock voltage of 1275mV. I then dropped the voltage of 1.5ghz to 1150mV which is the lowest voltage my SOC can handle at 1.5ghz and left 1.4ghz at stock voltages. So 1.4ghz is using much higher voltage than 1.5ghz. What I then did was open system tuner and then the CPU info page which shows you real time cpu temps and allows CPU frequency control. So the CPU stability test is running in the background, all four cores are maxed out to 1.4ghz and I am on the system tuner cpu page. What I am doing is waiting for the CPU temp to level off. For me 1.4ghz at stock voltage leveled off at 60C, I then upped the max cpu speed to 1.5ghz (which is running at a much lower CPU voltage than stock 1.4ghz.) The CPU temp immediately dropped to 55C and hovered between 55/56C, I then underclocked back to 1.4ghz and the temp when straight back up to 60C. I have repeated the test numerous times and the same trend keeps appearing. As you would expect a higher clock speed to produce more heat, this little test shows that undervolting really can help.

Because of this, I am quite happy now to overclock my s3 to 1.5ghz as I know now that is is outputting less heat than stock 1.4ghz. Please bare in mind that this test was done using voltages that my device can handle such as 1150mV for 1.5ghz, it doesn't mean your device can handle the same voltages. Even though this test doesn't tell us anything we already didn't know, I just thought it was fun to do. Also it is worth noting if you choose to repeat this test, you will only see a difference if the undervolt is large between say 1.4ghz and 1.5ghz. Undervolting by -25 or -50mV for the cpu is likely not to show much if anything with this test. Sorry for the long post, just thought I would share. :) Sorry if my explanation is bad, I am not that great at English even though it is my first language. :) (Give me C or VB any day over English :D)
[Galaxy S III General] omniwolf:
misleading OP

no, you misunderstand. the ASV level is like a measurement of your chip quality. In the first post of this thread where you have given a listing of "the stock voltage for all clocks for your reference", all you've actually done is list the stock voltage for an ASV6 level chip. This is only useful to other people with ASV6 chips. For example my chip is an ASV3 chip, and these values would not be stock for me, they'd be undervolted from stock. If someone with an ASV7 chip used your values, they'd be over volting their chip.

Please either:

get rid of this "reference" set of voltages,

make it clear that these voltages are for an ASV6 level chip, or

put down all the ASV level chip voltages and show people how to find out their level (note: to find out your chip level you will usually look at the stock voltages of your chip, making your reference redundant).

No,no problems here.

You have OC or UV?
[Galaxy S III General] Alex 136:
Yes there was, and OC and UV, but non-extreme, and in previous firmware everything was stable, the phone withstand any tests. Maybe the problem in the kernel SiyahKernel S3-v1.7rc1? Firmware and XXDLJ2 XXDLJ4 out later and have a lot of changes ....

[Galaxy S III General] jerverg:
Thank you so much for your guide. Though it's basically my first time rooting and everything. This made me learn a great deal about OC, UV, and what urged me to install a different Kernel than stock.

Just a question though, would there be like any other tests than the StressTest in STweaks to test if the settings were all good? Im using the StabilityTest app, is that ok? Because by StabilityTest i can also see the temperature while it tests the CPU @ max speeds.

Another question, what is the safe temperature? when i overclock my S3 to 1.6Ghz it reaches 51C, is that fine? im quite afraid of going above 50C so i clock mine at 1.5Ghz, which barely gets 46C.

My settings are:

CPU= 1500:1200mv, 1400;1150mv, 1300:1100mv, 1200:1050mv, 1100:1000mv, 1000:950mv, 900:900mv, 800:875mv, 700:850mv, 600:825mv, 500:800mv, 400:775mv, 300:750mv, 200:700mv

GPU= 266:875, 350:925, 440:975, 533:1000, 600:1025

My quadrant is just 5,625

Antutu: 12950

Nenamark2: 59.5

Basemark: 46.41

are they looking fine? and lastly would you suggest i change my firmware? im on the latest here http://xdaforums.com/showthread.php?t=1646610

Thanks a lot man! Sorry for being so noob!
[Galaxy S III General] bala_gamer:
impressive first post ;)

the temp you are noting(46c and 50c) are the temp of battery ,its ok to have those temps when stressing. you can also use set cpu and stress your cpu from the test there, if the test runs fine more than 10 to 15 mins then its fine.

The latest LJ4 jb is great.

There is a big difference between a newbie and a noob mate.. and you are a newbie , not the latter one ;)

Hi Bala, newbie here. I did all your settings for overclocking & undervolting. Also, done all the necessary testing but I think settings I made would be fine on my samsung s3 phone. But however, when I checked the battery on settings, I can no longer see other items except Android OS (100%)? Before I made these OC/UV settings, I can still see other applications that eat up battery with its percentage beside it like screen, some apps, cell standby, etc. but now only andoid OS at 100%.

[Android General] flapane:
I'm sure you noticed that when you record a 720p/1080p video with a smartphone, the bitrate will be pretty high, in the 10-15Mbps area.

This is not really necessary if you watch the videos just on your smartphone or on a limited size LCD TV, and you can just recompress it using x264 codec at about 2Mbps without severe quality loss (unless it's a sport video).

However you'll notice severe audio video out-of-sync issues if you compress both audio and video tracks and DON'T CHOOSE MP4 (which is the default container for the videos recorded by the smartphone) as default container for your x264 video.

Furthermore, if you want to compress and then JOIN different videos, you have to compress them one by one and THEN join them, otherwise you'll notice glitches in the playback.

I tried with mkv and avi but I kept having sync issues, so I thought that it was worth to share this tip.

SUPER @ video conversion program

Have you tried a video conversion program called SUPER @? Here's its link:

http://www.erightsoft.com/SUPER.html

The program can be pretty intensive in terms of memory used but it usually does a great job for me and bitrates can be chosen for just any vid type you might want to save to. Usually, I turn off my internet connection prior to executing it (so it can't do an update check) and run it by itself.
[Android General] flapane:
Yep, I guess it's something similar to Wondershare Video Converter Ultimate, it's just that I prefer more control over encoding parameters (so I tend to use programs such as Avidemux)
[Android General] mistermentality:
You've probably already thought of this but you can load your video in virtualdubmod and have it change framerate so video and audio match perfectly.

No re encoding needed and even on large files it takes less than a minute or two.

If you find virtualdubmod won't recognise the video you can download a suitable vfw codec and it should then.

Dave

( http://www.google.com/producer/editions/CAownKXmAQ/bigfatuniverse )
[Android General] flapane:
The problem is that vdubmod won't help, because framerate is not constant and it varies from some 19 to 30fps, at least on Vibrant.

In a lot of cases the fps number gets lost during encoding (and you'll obtain a video which has a constant framerate of 29.97fps), because softwares such as Avidemux doesn't have an option to leave the FPS untouched (or at least it seems that the fps number gets lost if you want to use MKV as container).
