OC'ing SGS

Hi there,
I actually want to know if it is harmfull to OC your SGS to 1.2GHz. Ofc it's better to run stock but is it of any real harm and how do you OC? I had a quick test with Galaxy Tuner and I must say when I use my phone heavily 1.2GHz is better. So if this is safe and done easily I would like to do this . Thanks in advance!

Well that seems like a small overclock, so if you have setcpu to your minimum with screen off, it should be OK.

Alright and how long can i use my phone when its on 1.2? Also next to that my phone is in a leather case when not being used so cooling will be a bit harder. Some more information from other people plz? I just want a consensus . Thanks for the quick reply.

my SGS motherboard burnt due to OC....
1 day while i was playing dungeon defenders with OC to 1200, with charger ON. suddenly the phone off it by itsself..
sent to service center, they said motherboard burnt!!!!
lucky they replace the board for me which still under warranty.
so high chance i think is the OC that cause overheat n burnt it.

No one can say for sure what would happen when you push a chip beyond its design parameters. Not all chips are made equal. Usually the standard speed rating is what all chips passing QC should be able to operate at. However some chips may be able to operate at higher speeds without ill effects while others may fail catastrophically even with a slight increase in frequency. So its anyones guess...
Frankly I dont see the need to overclock right now. What ROM are you using ? Flashing to a newer / better ROM can give you a bigger improvement than what 200Mhz can give you on a laggy unoptimized ROM, so why risk it ?? .

The fact you where charging, and playing a game probably had more to do with it than your overclocking.

+1, charging and gaming at the same time is never a good I idea. They both heat up the phone greatly

Hmm I'm running docs mod v9.9.5 XD with speedmod kernel and twlweaks enabled. So it pretty fast already however with the oc there is just less loading time. But you are saying that its useless?

If you can oc, that means you root right! either that or droidclock/setcpu correct?

it depends. i personally use tegrak overclock and for battery saving, i use overclockwidget. my sgs has been going for 2 days in a row with battery life only at 48% even with moderate usage(making smses, playuing games occasionally, etc.)

Hmm alright, these apps seems legit. What are your settings with these apps? Or should I use setcpu?

If the phone reaches a certain temperature, the phone stops charging, so i dont think playing a game and charging at same time is the culprit.
Granted that the phone would heat up A LOT quicker than usual, but being so hot, the phone wouldnt of been charging even with the charger connected.
there is now way of knowing whether overclocking is dangerous. Personally i think it is, you have to modify the kernel, modify system settings, modify battery voltage.
None of this is recommended, but we do it at our own risk...
Its as dangerous as running a custom ROM or LagFix. some devices are fine, some brick and burn to a crisp.
So choice is yours

Hmm i guess ill be sticking to 1ghz then... thx for the replies!

i do the same for my x10 n the phone running just fine.
in fact, before i sent my i9000 to samsung for warranty claim, i pass the phone to a local shop, the tech told me the OC cause the board overheat, then burnt it....

Actually tegrak oc works fine. ocing at 1.3 will crash first time but not crash anymore after the first time. ocwidget is not really useful for ocing but just to same battery life. when not really using my phone i will set it at 100mhz-400mhz. you can play angry birds on stock rom with little lag.

So you're saying i can oc.... but im running setcpu. I can OC with setcpu right? That brings another question when my screen is off what setting should i use for setcpu? In other words what is the minimum frequency?
Sent from my GT-I9000 using Tapatalk

100MHz is fine for the minimum frequency (for me at least) - this may vary between phones, give it a try.
On the subject of over-clocking though, you should take a step back and ask yourself "How much do I really need those few milliseconds less to load up Angry Birds".
I would suggest that Samsung did more testing than anyone on this forum.
All that said though though I take my phone up to 1.2 sometimes for ****s and giggles & to shut up smug iPhone fanboys

No. Don't set set setcpu to anything below 400mhz because when the galaxy slips into idle mode it cn sometimes be difficult to wake up
. I'd imagine such a low clockspeed would encourage such behaviour. I set my minimum at 400mhz and max at 800mhz. Spot on.

Over heat problems

What do you consider an over heat temperature for a phone?
My g2 over clocked @ 1.42ghz reaches 108 max when playing emulators and 3d games, is that consider over heat?

Nope overheat would be like 112 or once your phone turns off its self

So could that be reason for reboots on my previous G2 where temp would reach even 115?
I remember the sidekick lx 09 use to have the overheat problem and sidekicks usually warn you with a thermometer. Sign where the battery sign goes. I once put my phone in the fridge and forgot about it in the and left it there freezing for a good hour, luckily it didn't damage but it had ice flakes all over....

Eh... Well having a phone even over 110 can damage the component within the phone, that's why one my phone even gets near 110 I lower my overclock or even turn it off completely. LOL lucky ur phone didnt get messed up in the freezer.

"Overheat" for me is when the battery cover becomes very hot to the touch. This has happened to me once.

I bought one of those el cheapo batteries from Ebay and then trashed it when I realized that my phone was no longer reading the temperature correctly.

My phone gets uncomforably high when I'm using it overclocked that high while I'm charging. It usually cools down for me after I unplug it, and sometimes I take off my battery cover as the aluminum heats up pretty quick too.

The lid might act as a heat sink... I dunno but just a thought. I set my alarms at 40c

This may sound stupid but is there such thing as under heating a phone or over cooling it? Cuz in the winter phone temp is usually very low even when I play emulators going to college @ the train station

Maybe, it depends on the situation. Very low temperatures will affect the LCD temporarily and maybe cause poor battery efficiency but shouldn't affect the running of the phone too much. If its cold outside, the phone will be able to dissipate the heat more.
Transition between high and low temperatures can significantly affect it though. I think its high temp to low temp, the air will condense and deposit moisture in the phone. Again, its probably nothing to really worry about, its only extreme temperature change that does that normally.
Craig

I think cellphones are made with outside temperatures between -10° and +50° C in mind.

800mhz is enough

Quick, and great battery. Overclocking is pointless unless you play games on your phone, or care about your quadrant score.

Yup, I agree with you

I had a Milestone for 1.5 years on stock ROM (that is 550Mhz), pretty much served most of my needs perfectly....you know, the normal stuff you use your phone for.

I rarely notice my phone is underclocked... with smartass governor, it's more responsive than stock clocks with a less responsive governor.
Battery life doesn't seem improved, but I know that my weak signal is causing the problem here.

I Sunni it's different for me.. When in use it seems to drain about the same but last night I set the phone down around 11 worth 84% battery life and got up at 6 with 78% still and that's setting the governor to smartass

It's bad for me because my phone goes without signal about half the time in my apartment. I'll be moving soon so it's not a huge issue, but it is kind of disconcerting to feel my phone heating up from just sitting around doing nothing.

You could try disabling the governor and let one like, setcpu do it? Before I went Incredikernel I set up a profile in setcpu that whenever my screen was off it wouldn't run any faster then 128MHz but when on was set for either on demand or performance. Using two governors at the same time causes lag I've found so you'd have to be running a rom that doesn't already have one (that you can see and change) built in

Yea, this is true. OC'ing I thought it was giving me speed, but I actually took the time to really see the speed on OC'ing and to me it dosent seem to change. Well maybe alittle bit, but still. But yea, so I just hit 1ghz and I just leave it there.
Pete's latest w/Yennob-Base2 kernel at 1ghz and its going good.

Ahaha, yea. Everytime I would hit 1.3ghz or 1.4ghz for the fun of it, my phone would get that way too. It would get hot and it feels like it would explode in my face and yea battery life would drop like crazy.

Personally, I find myself running into a wall with RAM more than with processor power. I really hope the next Nexus at least doubles it.

Well the SuperOSR is only for nexus s.. If there was one for the ns4g, well then after reading that, I would be OC'ing like a maniac.

This. I'm really feeling the loss of RAM coming from a mytouch 4G. That extra 256MB really made a difference. Using juwe's RAM optimization script seems to help, though.

Ehm, how can Ram be a problem?
Android is managing it itself and can't run out of it, usually.

Things get killed that you don't want getting killed, and when it starts to run low things slow down considerably. It's not that something won't run, but it may run badly, or cause other apps to close that you were multitasking on, which is inconvenient.

How so? I normally get around 9-10 hours max with moderate use, also depending on the signal i get half the time.

I use netarchys latest bfs kernel with proton to undervolt all CPU frequencies to -20mv. And I have the CPU limited to 100-800mhz, with the on demand governer. With those 2 thing I get 15-16 hours everyday. I also usually let my batter get down to atleast 5% before charging.

Overclocking and battery

I'm wondering what is the battery life difference between 1000MHz (as max) and overclocked 1400MHz?
In most [low-end] phones little OC consumes a lot of power, but I don't see this issue in SGS.
Are you using your phone overclocked? How long last your battery?

I dont know why would you do that... I use SGS in max 800mhz(underclocked) and its perfectly fast... But regarding your question, prolly would be about a day and a half of battery with those settings on OC.

I think its perfectly fast as it is but to your question ... i think it really depends on how you use it i dont belive it will last more than a day of it is used as intended ...

I tried underclocking my SGS (aokp build 28) to 800mhz, and it crawled, never got to the first unicorn in past the boot animation. seriously.

I over locked up to 1200, no over volt. Don't feel any impact on batterry since phone is only less 1 percent of time in that CPU state.Rest of time it is idling.

Not much diff actually
Sent from my GT-I9100 using XDA

there can be a difference in battery life, but there does not necessarily have to be one I assume... after all, it is only the maximum available for the processor, most of te time it will not run at that speed... I for one do not overclock my phone (actually, I have underclocked it to 800mhz) since I have no need for these speeds (just using my phone for messaging and some browsing)...
please correct me if I am wrong since I do not know much about how the SGS processor exactly works

i cant see how it shouldnt impact battery.

You may use an app such as System Tuner to watch your CPU temperature. Mine get 50 celcius after 15minutes playing NFS MW... I dont know if it is still normal.

What version are you on? Mine used to be uncomfortably warm, but since 4.2.2, that has been fixed for me.

I am on Franco kernel, fast CPU, UV 150 (Default for 384Hz is 850, now it is 700). That's what makes me worry.

My Nexus has been getting uncomfortably hot. I first noticed it last night after getting to a friends place and took the phone out. It was really hot and the battery had dropped about 20% for a 15 minute drive. I checked the battery and Google Maps was showing at the top with the most usage even though it wasn't enabled.
I then proceeded to check the settings in Maps and turned off all the location tracking stuff which was unfortunately enabled.
However, even today my phone was again quite warm after driving around. Battery didn't even show Google Maps so that wasn't the cause.
It may have something to do with signal issues always trying to get the strongest signal as it doesn't happen when I am at home and not moving around.

Please help me.how to overcome or reduce heating problem of nexus 4.

is this your first smartphone? they all get "hot"

Only way to really reduce heat without an impact on performance would be to undervolt. Another way would be to underclock. Both you need a custom kernel to do.
