Overclock question - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I was wondering if anyone had any idea how fast you can actually o/c this phone without damaging the processors

Specific to each phone man nobody can say some can get 1.8 some can't go past 1.5 mind you that's just keeping the phone running past those points most bomb and phone boot loops and stuff

I prefer 1.8 but not all chips are created equal... Mine is a refurbished Skyrocket so im quite pleased. Try it out and go up in increments until you are either blown away by the speeds or your phone says NO! (which usually means a reboot frenzy or boot loops)

OK say it does end up boot looping a restore will fix it but internally will there be damage ?

Those clock speeds are considered safe so the damage would be from extensive strain from extended time at those speeds which could create high heat man chances are you won't have that issue overclocking is totally safe as long as you don't go crazy

The CPU is rated to run 1.2-1.7GHz fine so anything above those will depend on voltage and temperature. Higher voltage/temps are the ones that can cause degradation on a CPU when it gets too high. 1.8GHz should be fine but around that range you may see a higher power draw so if you use it too long it will eat up your battery.
Things that can contribute to higher temps other than higher voltages are use of GPS, keeping the screen on/high brightness, playing games while plugged in, using GPS on a car mount (heat from sun), or just plain browsing for a long time using the modem. Keep in mind that unlike computers and laptops, the phones don't have active cooling (fans) so if you plan to overclock just try to keep the phone in a low temp environment (don't leave phone in car!) :silly:

Just be sure to keep an eye on the temperature. If it starts running north of around 38° C then you should back it off.
That being said, with the badass or SmartassV2 governor I've had plenty of success setting the OC to 1.7

I think my phone is overheating...

When I use the phone to play a game or web browse it starts to get really hot on the top half of the screen.

Is there anyway that I can to see if the phone is overheating/getting too hot?

How hot is it getting? I'm pretty sure every smartphone experiences some kind of heat from gaming or streaming videos specially when you are charging it at the same time.

No and the phone does not get nearly as hot on wifi. Really odd. Also the phone was overcloaked before but I pushed it back to just 1ghz. My phone burning me for using the browder out is not cool though. Think there is an issue?

Well there doesn't seem to be anything wrong with the device since you said you put it back to 1 ghz. Really odd if you ask me. Maybe its a battery problem? Sometimes defective batteries cause overheating and can explode.

I'd recommend you flash and reinstall the ROM on your phone. Sounds to me like you've still go some of the old performance updates kicking in making the device hotter!
For me your temperatures are pretty normal. When I am not gamimg my max was 91F!!

Since you claim to have been able to move around the CPU frequency, I assume you are running setCPU. In setCPU you can look at Info tab where under the battery header it also displays the battery tempt. It's normal for the phone to heat while you are charging, on call for long or gaming for long duration but if you are seeing absurdly high reading for the battery tempt, then you better have it checked.
Hmm I had a overheating issue last night, woke up to my phone making a loud noise - I had set setCPU to make a noise when it goes over 40C and it did this today in the early hours of the morning whilst it was charging.
No processes were running other than the normal Live Wallpaper, Keyboard etc.. The phone was quite hot to the touch as well, so I just turned it off.
Weird thing is I have another profile in setCPU to have the max freq at 800Mhz and lowest 100Mhz when the screen is off so don't know how it got so hot?

Overheating

I'm running cm7 with Trinity kernel Oc at 1400 when I plug into the wall sometimes the battery gets hot also when playing VIP poker .all other apps run great. Any suggestions?

That's gonna happen while using the phone non stop, as for charging make a profile for when screen off/ while charging I do that and never have over heating issues... I also reboot the phone after I plug it in.

It seems like an error in the graphic drivers. I could come from a cold boot play a game til my phone gets warm then exit the game. After that the phone never cools down until after reboot. This has less to do about a charging profile and deals more with rouge code
Sent from my LG-P999 using xda premium
I'm assuming that's the performance kernel, and of course it'll overheat (to about 108-115 for normal highs). You're overclocked and charging the battery will be more hot than usual, you don't need to have it clocked so high for something like that, try it at lower frequencies if you're charging.
Why dont you just drop your clock speeds down to 1200. It should still perform like a champ. Expect heat while charging, I am running the ICS Eagles Blood ROM. It happens to mine too, without O.C.
It still has major bugs but it is far smoother than the stock 2.3 lg release that sucks to date.
Really you don't need to OC that high though, and if you do you should consider doing some undervolting.
If you are over clocking to 1.4gz your phone WILL get much hotter.
This us because your CPU is running faster, and generates more heat.

Obviously, lower the CPU speed. This shouldn't have to be said.

It's not an overcloking issue. I had the same problem at 1.2ghz and my phone was set to drop to 800mhz max when the screen was off. If it was an overclocking it wouldn't happen only when the phone is asleep because most phones are setup to use very little of the cpu when they are inactive.

Or, you had an app/s that kept running in the background, thus keeping the CPU awake. No G2X kernels currently support deep sleep (which would basically shut down almost everything when the screen is off), so that's another possibility. I'm on stock and don't need more than 760mHz per core most of the time.

my g2x running cm7 and the stock kernel will overheat when plugged into the wall. this alone caused many screens of death and constant reboots for me. i tend to just pop off the battery door before plugging it in and no more issues.

it really is not but it helps overheating a bit.its not like We OC to 1.8 but 1.4 still unnecessary.
This a dual core even at stock voltage still overheats.I seen single core devices really overheat.Plus Our experiences with overclocking,overheating would be different because each hardware make act different even though it's same phone.Also different locations,humidity temperature that affects phone too.You try to oc to 1.8 in the UK and it won't overheat lol COLD.

Try calibrating your battery.
Sent from my LG-P999 using xda premium
There is a rogue app in your drawer. download watchlist app, it will keep track on other apps which are hogging your system.
Battery calibration won't and doesn't do anything useful... its more then likely an app or something running constantly. What's your screen on times? Post a screenshot of your battery usage.

I'm on 2.3.4 with practically all the bloat and more removed, holy hell battery is terrible for me... if testing to find rouge apps doesn't work I'm gonna factory reset and just not install any thing. Today I didn't hardly use my phone (no work) sat around on the computer, paid some bills watched some movies and TV, sent two text messages and read 3 emails battery was at 65% after 3 ½ hours... 3 of which was idle time and screen off. Never had it so bad before.

Anytime. That's usually the first thing I do when I install a rom based on lg stock. That app runs constantly eating data and ram. You will usually gain almost 1mb of open ram by just deleting it.

On what type of usage? I can hardly get more than 8 hrs on medium usage .
What the hell is qem_warlock .it's been on my kernel warlock since I unplugged.
I pretty much don't play games and don't stream music or anything like large data usage. I call text browse and read articles and such, XDA and Facebook is about it for other usage though, light in most eyes, and I under-clock the phone to 700's usually.

Ya I agree, the phone at 600ish on stock kernel runs just fine for texting and calls and checking Facebook... usually what I run when I'm out at bars with my friends cause it usually ends up being a weekend without my charger, I've over clocked the phone maybe twice, no point in my eyes lol.

Simcard slot heating up on data use?

I am always having this issue on my infuse?when i use data or gps on my phone it is always having heating problems on my phone at simcard slot?anyone else having this kind of problem?i am thinking of going back to stock then start from there and my 2nd option is restore apps w/o data from tibu.

This is because the processor is at that spot. I have tried ICS ROMs and all of them have given me heating problems while on data and Wi-Fi. It's probably because of the kernel.
Try going back to a GB ROM and observe.

It's just the fact that your phone is in use...the only thing I could think of to prevent it from getting hot is underclocking...heat is just one of the prices you have to pay for fast processors...its a 1.2Ghz processor...that's pretty fast with nothing inside to cool it down...
It's like rubbing your hands together...the faster you do it the hotter your hands get

Why is my phone always hot???

My phone is literally hot all of the time. After about a minute of use it will become rather warm in my hand, no matter what ROM, kernel, or if I'm on JB or ICS. Oh and it didn't used to be this way. What's up guys? And suggestions to fix it?

Do you have a kernel that let's you OC if so the processor could be above 1.5ghz which would cause this. Try setcpu if you find it running higher

Our phone gets noticeably hotter than most phones because of the processing power. You gotta figure that our phones are running at a higher RPM than most others. Hot/warm is normal when you're actually using your phone. I recommend downloading an app like system tuner to check the actual degrees. I run about 120 F for a CPU temp when doing things on my phone which is normal. I've been told that a cpu temp of 150+ is when you need to worry and unplug and remove the battery etc to let it cool. Battery temps are normaly 109F and I've never seen mine go higher than that.
My first phone always got warm with minimal use. My replacement not so much.
Sent from my SCH-I535 using xda premium
Your phone may be defective, or you have a bad kernel, or maybe even an odd battery.
In any case, I suggest closing all background apps every couple of hours and maybe even undervolting your CPU when your screen is off to keep it cool.
It could be the rom... try clearing ram... or try underclocking the cpu
Sent from my SGH-I535 using xda premium
hey there, i happened to see there is a solution about hot phone issues, check it out http://forum.ksmobile.com/forum.php?mod=viewthread&tid=8&highlight=hot
I happen to be that problem and I observe it after a several flashing of Custom Rom and alll I notice is it depends on the Rom you flash and it's kernel or if you are on the stock rom, it supposed to be that your apps including background apps are drinking the juice of your battery. You can try Greenify to limit the background apps
