Ever rev an engine into the red? Did the engine blow up on the spot? unlikely. However if you constantly KEEP the engine in the red it will eventually break down.

Same thing for OC phones. The processor in the SGS was designed for somewhere around the 1ghz mark. Pushing it 110% likely wont kill it, they build allowances and tolerances into these things to help them last longer. Push that processor to 150% and you are risking serious damage.

Monitor the heat, if you notice its getting HOT then you should really pull the battery and let it sit for a while. Nobody here can say its safe to OC your phone like that, its a calculated risk you obviously didnt spend a lot of thought into.

TLDR: Just because you CAN doesn't mean you SHOULD.
[Galaxy S II Q&A, Help & Troubleshooting] Visentinel:
Actually its my thought the reason I haven't been using it on 1.6 yet, and why I'm asking. Iv been ocing my pcs since the late 90s

Now the reason I'm asking here is because the cortex a9 was designed for up to 2gHz operation, but this phones design may or may not provide adequate cooling, that's why I'm asking if other people have any negative experiences with this.

Were not actually over reving the chip its more of a environment issue with cooling/ventilation.

[Galaxy S II Q&A, Help & Troubleshooting] Phistachio:
You do have to have in mind that PCs are much safer to OC, so we shouldn't really compare brtween them.

Regarding the Phone OC, I haven't OC'd mine and probably never will because I have all the horsepower I need, but I think the "safest" OC is between 1.3 and 1.4GHz, since that's a range that all CPUs are designed to overtake (max 200MHz range ).
[Galaxy S II Q&A, Help & Troubleshooting] systemcrasher:
mine's been oc'ed, uv'ed pretty much within the week I bought the phone in june.

I've got it set to clock between 500-1600Mhz on demand and I've not had a problem yet. Mind you, not many tasks you do on the phone will actually require 1600Mhz and my phone's CPU clocks mostly between 500-800Mhz.

Playing some games or doing quick video conversion will push to 1600Mhz but I rarely play games on my phone and video conversion is short process - burst of 90 seconds to 120 seconds at most. So I think you should be alright so long as you don't leave your phone CPU at 1600Mhz at all times.

Like you said, it is the cooling and ventilation system on the phone, which you can't modify.. Unlike PCs, where you can install bigger fans or water cooling systems. So if the phone isn't constantly cooking itself inside, should be alright.
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
You should already know that OCing anything is dangerous since you overclock PCs,so I'll skip that part.

Well,if it's dangerous for the phone...It depends.Yes,the processor will die sooner.Yes,you risk frying your device.No,you don't have to push it to the limit(don't push it more that 1450μV,that's the general advice for 45nm chips).However,my thoughts are:

-I won't still have the device when it's time for its CPU to get fried,so I don't actually care.

-Something else,probably the Amoled screen,will make the phone useless by breaking sooner than the CPU will.

-This winter here is really cold(for our standards anyway),so heating has been taken care of.During hotter weather,I kept multiple temperature profiles in SetCPU,so that frequencies get lower as temperatures get higher.

In the end,what matters most to me is to have the experience I want.And with OCing my phone I get it.I'm happy with it,that's all I wanted.So,it's personal preference.Some feel they don't need it,others feel they do.Decide for yourself,that's the best advice.

PS:In case you are using Siyah kernel or CF-Root with Tegrak overclock,try lowering your clock by small steps(8Mhz is the smallest step) for a sane voltage,say 1400μV.Sometimes small increments make big differences. :)

Don´t oc sgs2.

I got my mobo fried without oc.

Service center replaced everything else but housing and screen.

I used it 2-3 hours in a row, installed programs and put it in charger.

In the morning, it was completely dead.

Overheated because of the use and charging.

So think about twice before using oc 24/7.
[Galaxy S II Q&A, Help & Troubleshooting] kaukassus:
how can you tell, that its dead because of the use and charging, if you didn't even OC'ed?
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
I bet you didn't know there are faulty products out there that show their faults during intensive usage,eh?Mine's running at 1.6GHz(give or take a few MHz :p ) for months.I've played games while charging countless times.And my phone is still here,intact,so that I can write this here. ;)
[Galaxy S II Q&A, Help & Troubleshooting] Buffalee:
Of course my sgs mobo could have been faulty.

When the mobo fried it was hot, i mean hot.

I didn´t look temperatures.

It didn´t wake up even using jig.

I sended it to service.

If they had succesfully woke it up, they wouldn´t fix it on warranty (rooted).

Normally oc would be fine because it´s using powersave and underclock it.

But if you play like 2 hours on 1,6Ghz it can get too hot (over 60c on cpu).

I can´t recommend that kind of temperature.

And nobody here knows what kind of vrm´s phone has.

Also cooling plates are not designed for massive oc/voltage.

Of course temperature depends on voltage more than the clock speeds.

It´s up to user if he want to use it that kind of voltages/speeds.

I would´t use it 1600Mhz/24/7.

Generally i know what i´m talking about (using water on pc...)

Just look for temperatures and don´t give too much voltage (as low as possible).

Of course you don´t know safe voltage limits, but try and look what other have been using.

Don´t oc much if you don´t know what are you doing.
[Galaxy S II Q&A, Help & Troubleshooting] danielsf:
@tolis626 Hi, I have oc'd to 1.4ghz for the last few weeks, and I have under volted it to 12.75mV, the same as you, have you had any problems at that voltage? Also, is your 1200mhz voltage stable as it seems very low, to say that it was, at stock, 13mV. Furthermore, have you ever tried to under volt 1600mhz please?
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
I know what I'm doing.I know the risks,that's why I don't encourage anyone to overclock as much as I do.I carefully monitor temperatures and voltages over long time periods.Rest assured,I won't come back here crying. ;)

Well,since 1400MHz and 1600MHz aren't stock clocks,you don't actually undervolt them.You rather choose a voltage for them as there isn't a standard one.

My phone is stable with the voltages in my sig(I've only changed 200Mhz and 500MHz voltages a little but too bored to update my sig :p ) for months,so yeah,I'd say I don't have any problems.This doesn't mean that no one will.Your phone might need 1325μV or 1225μV for 1400MHz.Every phone's CPU is unique in its own way.
[Galaxy S II Q&A, Help & Troubleshooting] danielsf:
@tolis626 Thanks very much, one more stupid question please, will under volting from stock Samsung voltages, even if it's stable, decrease performance compared to stock voltages on an average exynos processor please, aslo will undervolting from original kernel clock speed increase the processors life span? I have researching this and came up with nothing. :)
[Galaxy S II Q&A, Help & Troubleshooting] TheSniperFan:
Will it break your phone? Not directly. It will shorten the lifetime.

Besides that the heat can indirectly kill your device.

I'm just curious:

Why overclocking the device? I have mine underclocked to 1 GHz max. It still has enough power to handle everything.
[Galaxy S II Q&A, Help & Troubleshooting] danielsf:
I have just been messing around. I can get 1.6ghz perfectly stable at 1350mv, I tried 1325mv and it hung up after about 2 min of use. I can also get my 1.4ghz down to 1225mv's and 1.2ghz to 1.200 it is rock stable and I haven't tried lower voltages on 1.4 & 1.2.

I am going to keep 1.6@1350mv & 1.4 @ 1250mv & 1.2@1225.
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
No,undervolting will in fact prolong your processor's lifetime,albeit negligibly,because with less voltage less heat is generated.It's plain physics. ;)

Overclocking on the other hand will reduce your CPU's lifetime.The damage(mostly electromigration) is dependent on the CPU and how much you overclock.Quite frankly again,you won't still have the phone when enough damage is done for it to break.If the slightly lower battery life doesn't bother you that much,I say go for it.

Dude,that's some nice UV!Mine instantly crashes when I set it to 1375μV at 1600MHz.You're lucky.

Oh and,most probably your phone can handle 1200MHz at 1150μV. ;)
[Galaxy S II Q&A, Help & Troubleshooting] danielsf:
Thank you very much for all your help :D I tried undervolting 1200mhz more, I got to 1075mv and it was rock stable, I don't think I am going to try anything lower than that. Just for info, I'm on SiyahKernel v2.6.2 :) Thanks again :)
[Galaxy S II Q&A, Help & Troubleshooting] oic0:
CPUs care a lot about voltage and don't give a rip about MHz except for the minor heat increase. The chip in my phone is a bad clocker though. If I could get 1400mhz to work at close to the stock 1200mhz voltage I would do it in a heartbeat. Sadly mine requires a healthy bump so I abstain. At least until I can afford to replace it ;)

Number one rule of overclocking, don't push the voltage if you can't afford to replace it
[Galaxy S II Q&A, Help & Troubleshooting] Gnarfsan:
I discussed the topic of overclocking processors with a friend of mine who design cellphone CPUs. He told me that over the lifetime of a CPU, the insulating oxide layers break down. This process is considerably faster at 40% extra power and frequency. So don't expect it to last as long as a normally clocked CPU. So the question is how long it would normally last.
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
My old PC's CPU was a single-core AMD Athlon 3000+ at 1.8GHz.That beastie had reencoded more movies than I can count,which meant counltess hours of the CPU running at 1.8GHz.It also was compatible with everything.Even MacOS ran perfectly on it(Hackintosh for those who don't know).Sadly,the CPU fried after I overclocked it heavily(its silicon even grew a pair of boobies :p ) after 8 years of heavy use,including but not limited to gaming and movie reencoding.

R.I.P Athlon3000+, 2003-2011 :(

Anyway,what I want to say with this,is that CPUs' lifetime is long enough.We can afford frying it sooner than normal.Unless someone wants to keep their phone for like 6 years. :p
[Galaxy S II Q&A, Help & Troubleshooting] Gnarfsan:
Well it doesn't just die in an instant. It will make more and more errors until it's finally too unstable. Besides, the insulating layers are not getting any thicker. It might last 5 years or it might last 1. Who knows. I'm just saying there could be a risk. Personally I don't care much. Dead phone = an excuse to get a new one :D

Recommended Stress test apps

so... i'm using my sgs2 with 1.325 at 1.6ghz, 1.250 at 1.4ghz and 1.175 at 1.2ghz.. what kind of applications should i use to stress test it and see if it's stable??? will quadrant do the job?

Thank you guys...
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
1325μV for 1600MHz>?!?< :eek:

Anyway,delete Quadrant,it doesn't do ****.If you want to stress test,either try playing some HD video(preferably RMVB as suggested by pikachu01) with software decoder(such as MX video player's one) or download StabilityTest app from market.SetCPU also has a stress test functionality.
[Galaxy S II Q&A, Help & Troubleshooting] jzmtl:
Stability test doesn't work, I can run it for an hour withour error but HD game will crash within minutes. So for me the best test is to run HD games.
[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
You either didn't use an appropriate governor for stability testing(best here is performance) and it scaled down during the test,or crashes in games are GPU and not CPU related.Do you OC/UV your GPU?
[Galaxy S II Q&A, Help & Troubleshooting] Visentinel:
@tolis and @gnarfsen

You guys rock :-)

I'm the same, when I ask about Safeness I'm really mostly concerned to get least 12 months of stability lol.

The good thing is when the CPU starts dying due to the oxide breakdown all you need to do is reduce the oc, the CPU will begin to work properly again. But its a signal to start phone shopping!!!

I have been running 1.6ghz on siyah kernel with 1.425 volts, its rock solid stable.

I have tested 1.6 with 1.375 volts but it crashed as soon as a little heat built up, had to pop my phone in the freezer to get it to finish a boot up thanks to forgetting to untick apply at boot in setcpu lol.

I am also using tegrak 2nd CPU to keep both cores on full-time. It's so awesome !.

1. 6 + fulltime dual core = WIN

But wait there's more, there is no governer better than ondemand if you know how to configure it for maximum power.

In setcpu set the sampling rate to 30000 and the up threshold to 80 or 90.

From a complete idle setcpu shortbench will score around 95ms! No other governer has given me such responsiveness. I have my threshold on 80, I score around 80ms.

As a comparison performance governer will yield as low as 68ms

[Galaxy S II Q&A, Help & Troubleshooting] tolis626:
Try using an up threshold of 60% for ondemand like I do and you'll see what it's all about. ;)
[Galaxy S II Q&A, Help & Troubleshooting] jzmtl:
The app named "stability test" will change your governor and automatically scale to different frequencies to test them all if you give it root permission.

No GPU tweak, I was testing CPU UV value and adjusting it slightly higher fixed crash.
[Galaxy S II Q&A, Help & Troubleshooting] Visentinel:
LOL true, but for that extra few ms better in shortbench ain't worth the drop in battery life for me. I had a HD2 before this and I'm scarred for life when it comes to battery life :'(

[Android Themes] Phienyx:
Hello, I've been working on a Tron Legacy styled theme for my for for some time now. I am using Go Launcher Ex. I have most of it set as I'd like it, but I am working on one last thing for the time being. I am using Widgetlocker for my lock screen and would like to use Desktop Visualizer to add to it icon widgets in the following style: https://market.android.com/details?...sMSwxLDEsIm14LmxwaWNvbnBhY2sudHJvbmxlZ2FjeSJd

Unfortunately, this icon pack does not seem to work with Desktop Visualizer and the icons that come with the Go Launcher version of these icons do not work with DVR either.

What I am asking is if anyone knows of an Icon pack in this visual style that would match this style/color? If not would anyone be willing to create an icon pack that matches this, that would work with DVR? I would be more than willing to even pay for an icon pack in this style that would work with DVR.

Thanks for any info provided.

How long do you guys plan to keep your Galaxy Nexus? I plan to keep it for 2 years at the least, I see no phone that could potentially be released in the future that I would want:D I don't need/want quad core or 3D displays, i don't see mobile gaming even fully utilizing the power of current processors in the near future.
[Samsung Galaxy Nexus] kazuni:
I don't know to be honest with you. So far I am greatly satisfied with this little monster, but at the same time I have used many android devices before (10+). But this may be the game changer, I probably will keep it for a while :rolleyes:
[Samsung Galaxy Nexus] fillyo:
My line is eligible for an upgrade on January 17, 2012, I am guessing I will not upgrade until there is a killer quad core perfectly spec'd phone, or some revolutionary unforseen phone that we don't know about. No rush now.

I'm due an upgrade in Nov/Dec next year, I may consider whatever's good then if it has 3D and NFC but it depends if a new major upgrade to Android OS is due, if it is I will wait for the next Nexus as I'm fed up of being behind with the OS which is why I went for the GN in the 1st place.
[Samsung Galaxy Nexus] martonikaj:
Well there will be another major upgrade to Android this time next year. That's how its going down.
[Samsung Galaxy Nexus] ThemBonesAreMe:

[Samsung Galaxy Nexus] jauffRINDIR:
Most likely when the next Nexus comes out, or if Samsung release another killer Galaxy phone (Probably not the GS3, too soon and I've spent too much money on the GNex).
[Samsung Galaxy Nexus] daleski75:
I think out of all the android phones out now the nexus more than likely has the longest 'shelf life' due to the fact that google will keep on updating it for as long as they can until the next iteration of their OS is simply too big to run on the phone.
[Samsung Galaxy Nexus] schriss:
I usually but a new phone knowing It's only for 1-2 years.

This time it was different, I sold my 3 months old SGS2 and got Galaxy Nexus for it's higher resolution display (and I love this phone just like SGS2).

When getting GN, I already knew I will be replacing it with SGS3, hopefully sometime next year. Unless the specs do not justify the upgrade. GN is great and not lacking in games department, I mean Dead Space runs fine. But it probably is maxing out our GPU. I know sooner or later we will see a great game that will not run on our phone, something that only runs on Tegra3 and up.

I'd also like to see similar solution in SGS3, that uses 1 extra CPU core for background jobs, like they did on Tegra3. So you get more processing power AND better battery life at the same time. I wouldn't care if it's Tegra3 or Samsung CPU as long as it has that feature and has decent (future-proof) GPU. But seeing how nVidia is progressing in mobile gaming department (and owning desktop nvidia GTX480 monster), I tend to want TegraX in my future phones.

[Samsung Galaxy Nexus] bmolloy:
I agree with the OP that the specs on this phone can keep you going for a long time. I have at&t, however, and I am sure I will be drawn away by a phone that has LTE on at&t's network. (But first they need to giver southern California some LTE love) When that happens this phone will stay in the mix as a T-Mobile Hotspot when needed and a travel to other countries phone. The penta band radio on the GSM model is the whole reason I bought the GN. I don't see any of the carriers in the States putting out a phone in the future with a competitors frequencies, so this will stay in the phone quiver long after it is replaced.

Honestly, I'll probably keep mine until the iPhone 5 is released. I know most people on XDA cringe at that thought but I already miss a bunch of my iPhone apps as well as the silky smoothness of iOS but I simply got bored with it.

I got bored with iphone after 3 months. Email client couldnt handle my email account with hundreds of emails on it. And got bored with UI quickly. Now when bored I build theme myself. I'd give iphone to family members, so that it would just work for them and they wouldnt bother me. But for me iphone is too simple.

It does look nice but the rubber cases people put it in make it look ugly and fat.

I never use screen protectors or cases - it ruins the experience.

Will be keeping my nexus until the next nexus comes out. Hopefully Verizon will get the next nexus as well. I'm hoping their launch debacle didn't make Google not want to go with big red again.
