Galaxy s3 cpu problem (i guess) - Galaxy S III Q&A, Help & Troubleshooting

Hi, kinda the 3rd time i ask and no reply or whatsoever... Almost every time i open a high resolution game or some benchmark test, my CPU goes from 1800mhz (overclocked), to 800... this always happens when i am on performance governor... It's really frustrating to always open set CPU and fix it. Any help would be appreciated.
Best regards

The answer is quite simple, but your attitude makes me not want to say anything.
You have a terrible attitude.

It is likely because of the CPU overheating. The CPU will throttle down whenever it exceeds its thermal limits.
I'm terribly sorry for replying four hours late. Do you want a refund for my incompetence?

Its like ballsofsteel said, its due to throttling because of heat.
Firstly you don't need the CPU at 1.8ghz, secondly you shouldn't use performance governor as it keeps the CPU at max freq all the time. Leave it on pegasusq and if you wanna overclock then 1.6ghz is enough.

I have tried to use pegasusq but i really like to have my phone as smoother as possible. Any other way to do it? I dont really have problems with battery draining because i keep a charger with me always...also one more question, what i/o would you suggest me? Sorry for wasting your time

Just drop the up threshold in governor settings, its at like 85% stock so drop it to 70-75% or lower if you want. You can tweak those other settings to make the phone snappier. Pegasusq is important because it is a hotplug governor and turns cores on and off as they are needed. I always used deadline so that's what in would recommend.

enyo... I have tested with glitch kernel at 1.7 ghz and i currently hold the record benchmark for this device on antutu using performance governor. After testing for a half hour at that speed i fell asleep with the phone stuck at that speed. I'm typing this message with that phone now. That was done with glitch v13. The most i ever got from high clock speeds was freezes and reboots.
However, if you get stupid with live oc the story can be very different.
But to give an idea of what my phone handled back then, go to the cm7 glitch thread and check what the gpu/buss speed was at 1.7ghz. But remember that those bus/cpu speeds, and voltages were finely tuned by tk , and you probably won't be able to push that hard with live oc.

It's all luck. Chance. Fate. If tk has not burned his phone yet i would say you have a lot of catching up to do to get the mileage he has. I had mine overclocked 1.5ghz for a few months.. And guess what, i have never monitored temp. But hey, i pay an extra couple dollars a month on top of insurance for lifetime warrantee. So i think my phone burning up would fall under that. But anyway, your stressing out to much over it.

no heat and i use it daily...first time i can ever say this when overclocking to 1500. i agree with neh4pres posts...becareful with live oc it can screw your device up quick. most folks will never see any benifit by using live oc imo anyway. part of the reason why i just use vc...
I actually use 10% live oc and 1200mhz step... All voltages stock. Fully stable and it FLIES

I must have every bit of speed. That said here's the setup:

Live OC is the way to go as you get a boost to your GPU and RAM in addition to the usual CPU bump.

Tbh i would recommend any custom kernel that allows you to undervolt, i.e Siyah
i currently have my phone running 100mv below stock and my battery life is better than it was stock
Uv is useless in s3 seriouzly. How much can u save.
Sent from my GT-I9300 using xda premium
Well think about it, 4 cores consuming 1400 millivolts each.
Undervolt by 100 millivolts and you have saved the equivalent current of 400 millivolts (100 per core).
Thats close to a third of the total consumption of one stock core.
Sent from my GT-I9300 using xda premium
Undervolting is pointless unless you are planning on overclocking and want to reduce heat.
Battery savings from Undervolting are about 2-3%
This is insignificant and isn't worth the potential instabilities.
Plus it's not even a big consumer of power, The power the cpu uses is dwarfed by everything else in the phone.

The CPU is still the largest consumer of power unless you have extremely bright colours showing on the screen. Plus the phone can be undervolted very far below stock settings as it is, so savings should be more than what you quoted. For gaming I'd say my mali patch would bring quite some advantage in terms of power, since the CPU lock is gone and ASV scaling on the GPU can actually take place now, Netarchy already included that into Ninphetamin.

Somewhere on XDA I've been reading about some1 testing high (nearly max) voltages against as low as possible voltages (but if I remember correctly it has been a single core CPU). His result of this test was that even with such extreme voltage differences he was not able to save one percent of battery.
While I'm not too much into CPU voltages and undervolting I can't say anything about it for sure. But I'll be looking for that article...

I think I know what thread you are talking about and I completely disagree with those findings, at least on the S2 I did proper measurements myself with -100mV on various frequencies and the power advantage was almost equal to the CMOS power formula f*V² on full load applications. I advise people to stop comparing such articles from different architectures as the Snapdragons or the OMAPs as they have different types of power saving states which influence the measurements greatly. The Exynos is relatively "stupid" in terms of lower power states and relies heavily on DVFS scaling so voltage brings a greater effect on the dissipation.

Sent from my ADR6410LVW using xda app-developers app
depending on usage, I imagine it would be minimal. I assume the CPU underclocks itself when idle and only goes up to 1.5 during heavy usage like playing a game or maybe launching an app. so if you aren't doing this most of the time, then I would imagine the power usage would be pretty much the same. I'd be more interested in how much hotter the phone gets when playing a game.

Hmm... That is a little bit more of an effect than I expected.
Of course, we will probably be able to minimize the effect overclocking has on battery life by installing custom kernels (once we have them) with more battery efficient CPU governors. As far as I know, the default CPU governor for Android is still ondemand, which scales up to the maximum frequency very easily. Something like smartassv2 or lazy would probably do a better job.

CPU, GPU heat up when playing modern combat 4 [SOLVED]

I bought the game. Btw
When I play the game, my device heats up and just wondering if there is a app for showing the CPU temp. And what is the safe zone for the CPU? But I really need that app its not only mc4 but that my main question. I played for 2 hours straight, ended up with 12% battery and the phone felt very hot.

These games are really GPU intensive so my bet is you slow down your gaming. I mean take breaks from time to time. App, I don't know any but you may find it and it may need root. Plus do you have a case on? If yes then it is one of the reasons why your phone is heating up so much. Can you also specify the position where the Phone feels the hottest.

my phone heats up in the bottom right. I don't use a case, i am fully rooted and have a custom rom. i don't have any way to read what temperature my phone is heating up to but at a guess, i would say around 50 C or something i don't know My old s1 actually plays the game smoother than my s3!!!! i think the heat is throttling it. i haven't overclocked my phone.
The processor is at the bottom so it will definitely heat up there.
The best thing you can do is to take a break when playing for a long time. Don't charge when playing, turn power saving off when playing (works for me).

yep will do, just a few last things, i modified the UV a bit. My phone started to crash alot so i changed them a bit. for 3 hours of gaming my CPU went up to 50C still kinda warm but hey, it quadcore. to keep it at 30C or 24C idle you would need a water cooler. LOL
Ah yeah. My settings are a bit low.. Stable enough but hey every device is different. Rarely felt my battery warm to the extent I go oh it's hot. Good luck with mc4.

I think they're both great you can't go wrong with either kernel. It's like choosing a lamborgini or ferrari, they're both awesome but it truly comes down to preference.

Sorry for a question within a question, but what does undervolting/overvolting do? I've only ever tampered with MHz frequencies.

Don't worry.
Undervolting is basically adjusting the voltages so the cpu uses less voltage aka electricity. It helps a little but it can make your phone unstable so watch out. Of you undervolt use the system tuner app on the market. You should definitely under clock if you want to save power too. When you undervolt be sure to underclock, and don't do it too low or your phone might freeze! That's why your shouldn't go so extreme on it.
Overvolting is basically adding more voltage to the cpu. There is no point in doing it for our amazes to be honest. It is already a battery hog. I guess it can help if you want to over clock a lot but there is absolutely no point in doing that.
In older legacy phones if you wanted to over clock because the cpu would be so weak, like 600mhz then you would have to overvolt to over clock to like 1ghz if you were lucky. Our devices are 1.5 ghz dual core and sense isn't THAT bad. There's no point in doing overvolt in this phone though.
PS, check out my rom in the development section.

I just saw it in Venom Tweaks and was curious. The most I underclock to is 1 GHz; cuts down the CPU maximum by a third and doesn't hinder performance to much. What voltage would you recommend at that clock speed?
P.S. I have I plan on flashing it to try it out when I get WiFi access. Trying to cut down data usage since I don't have WiFi at home.

1ghz is perfect. As for voltage it really varies but I subtract 75 or 50 mv from all voltages.
PS. Oh nice, hope you get wifi soon then.
