[Q] Is it really safe to keep overclocking to 1GHz?

I am new to android phones. And i have no experience about overclock.
Will my cpu easily break down due to keep overclocking?..
Honestly, i seldom change my cell phone model, i want my defy can stay a life at least 1.5yr.

i think overclocking can't really damage your phone, voltage can. so i suggest you keep the voltage around [email protected] (default is [email protected], so this should be fine), and if the phone doesn't hang or reboot, you're good to go but you could try lowering vsels, you know, the lower the voltage, the lower the power consumption, the heat and the chance to fry your cpu but i'm not sure!

Yep, 1 GHz is safe, I'm using [email protected] as well, and the CPU is capable to run easily at [email protected] continuously. The leaked Gingerbread ROM from Motorola uses 1GHz as well, so don't worry, you just have to find the safe vsel settings.

thanks for replying, i m currently using 1GHz @ 58 .. Everything is alright
Should I make the voltage as low as possible?

yeah, just to lower the power consumption and temperature, but it isn't necessary.

Can you share your voltage setting please..?
I do the stability test and it gets successful run for 5min then this means the setting is okay?

i don't overclock, just undervolt, here are my settings (with setvsel):
800MHz - 45vsel
600MHz - 30vsel
300MHz - 18vsel
up_threshold: 90%
actually if you wanna make absolutely sure your device is stable, you should run it like for an hour. but if it runs for 5 minutes without error that's quite okay, you shouldn't have problems with those settings

Thanks so much, i m trying to lower my voltage setting.
Besides, i want to ask about the battery temperature, what is the maximum temperature before getting damage to the cell? I usually goes up to 37~39 degree celsius.. is it normal?

mine is usually around 29-32 °C, but i have it undervolted, so idk. but 37-39 seems a bit high, that means the cpu temp is way over 40 degrees, you should check it out!
EDIT: tried stress testing for 20 minutes with [email protected], it went up to 35°C, so you should definitely find out what's wrong with your device!

I actually underclocked to 600MHz, since I couldn't see a big difference even at 1200MHz in normal usage. A Pentium3 at 4Ghz will still not perform as well as a slower clocked new CPU for example, CPU design is more important - what instructions it supports.
Battery life is more imprtant to me and heat is very bad for Li-ion batteries too.
Also I found changing the CPU governor to "interactive" made a difference in GUI responsiveness and I have had less stuttering.

so, what's your standby lifetime after underclocked cpu?

I can see the performance improved when i was watching flash video on browser. But honestly, i dont think there are anymore huge difference after overclocking..
But as the battery life still remains quite well, i will still keep overclocking to 1GHz.. Isn't it a good idea?

lol... What happend to HD and THD games... Did u try playing them at 600mhz??

Overclocking to 1 GHz with the right voltage values seems to be absolutely no problem for Defy.
BTW, does anyone know whether it's possible to set scaling governor to "Interactive" mode under Froyo? Gingerbread kernel let me set it, but I haven't found the way under Froyo.

Battery life was a little bit better, the display and 3G always draw a lot of power.
Standby time got better, but I don't use very low vsel any more due to errors in YouTube and dropped connection of radio streams.
Before I used 300-600-800 at 20-30-48, this was very stable in stability test, but for example Youtube would start showing "error playing video". After I increased vsel, it went away.
I mostly did it to lower temperature, optimal temperature for li-ion is around 25°C according to Wikipedia I think.
I don't play 3d games, they would benefit the most from overclock I believe.
Angry birds RIO for example would stutter for a second or two after a level loaded, but it would become as smooth as at higher clocks, when I wait for a second.
I hope flash gets better, when hardware acceleration gets enabled in Quarx's CM7.

I was running [email protected] for a month straight. No issues at all. The highest my temp reached was 112F after playing games for about an hour straight. I now just run it at [email protected], and it's plenty fast for me. I did some "testing" with all the options in SetVsel. It's not science sound, but if you use the Gingerbread Icon in the notification bar, and are running at stock (800 speed) you will notice when the CPU maxes out it doesn't even reach full capacity. I found Words with Friends to really use the CPU, and at 800 it pings the meter in the orange (The notification icon shows green, orange, and red for "zones"). If I overclock it at 1000 or above then the meter goes into the red. I don't know the exact number it switches from orange to red, but being at stock 800 is well below what the chip can really do since it doesn't even max out the meter. I hope I didn't confuse anyone. It makes sense to me.

weird...my cpu at any game reach the 800mhz
yet even in normal situations like browsing through the files on the phone it reaches 800mhz
and also despite the values i use in setvsel are not high(which is:
24 @ 300
34 @ 600
48 @ 800
)
the phone still reaches maximum 38C when i play games and if i set the value in the third vsel the games starts to hang!!
seems like i am the only one who have these problems..but why
anyone have any idea
im running stock arabic froyo btw
if someone can confirm to me that i can keep Arabic language if i installed another rom using custom restore in nandroid then i would be using prays or official 2.3 but no one answered me about that
anyway the important thing is anyone knows why my cpu temp is always high?

Well ambient temperature is important too. If it is 30°C where you live and your phone's temperature is at 35°C I'd say you are good. If the outside temperature is 10°C and your phone is dat 40°C I'd say there is something wrong (unless you were playing games or watching a movie).

in my opinion, it is definitely safe that you overclocking to the leaked moto level.
however, the voltage is still a mystery.
there's no constant conclusion about this.
i'm using [email protected], [email protected], [email protected], and it works fine for me

I'm getting really annoyed. No problems clocking up to 1100mhz with stock voltage (58). But changing the voltage settings, even slightly, makes the phone more or less unstable.

[Q] overclock

i have setcpu and the lost rogue v1.3 and i what to put it at 1704 MHz but it freezes or reboots, so what could i do? what voltage?

You can try upping the voltage, not every phone will run at the highest speeds. Overclocking is luck of the draw, not every processor will react the same. My phone requires 1550mv @1.6 to be stable and 1.7 is not stable. There is no real advantage to running the processor this high anyways. 1.2-1.4 is the sweetspot, 1.2 does everything the phone needs to and you usually have room to underclock, to increase battery life and usability of the phone. Benchmarks can be fun but imo, stable phone @ lower voltage > semi-stable benchmark monster @ high voltage.

Agreed, I have tried all sorts of overclocking and always go back to 1.352 or 1.2 because of stability. Sure you can bump it up and get high benchmarks, but who cares it is just a number. I would much rather have lower numbers and a stable phone.

I am running New Senzation ROM with the Desparado Kernel and I am running smooth and blazing fast at 1600. I actually can run at 1704 but dont like to overclock to that speed for very long but havent had any crashes.

Wanna trade phones? I wonder if you could push it higher? I can get mine to run at 1.7, but it will eventually crash within a few minutes. 1.4 seemed to be the most stable (and got the best quadrants) , but I don't bother OC'ing anymore. The phone runs fine without it. I don't really ee the point. I do notice some lag hear and there at 1.6.

I almost always am in the 800mhz range and rarely does my phone jump to 1ghz and definately almost never hits 1.2ghz. Besides trying to get your phone to give you some meaningless number as far as the real world is concerned ( quads) there is zero reason to ever overclock THIS phone. This phone has better battery life than iPhone with a slightly higher clock which is awesome. It actually performs the best of any phone to date. People conatantly hate on apple so hard to the point that when apple actually does something thats honestly great people still see the cup half empty with them. Apple has some of the best battery life of any smart phone to date. It also is one of the smoothest UI's out. They are a smart company and have great hardware. The example i like and cheer them on for is there way of using there cpu in a certain way. They have a really beefy cpu and then they underclock it quite a bit so it just sips battery power. Yes apple doesnt actually multi task so its easier for them to achieve battery life this way easier and it requires more cpu to run our phones as they have REAL multi tasking but i use the same idea. I underclock my phone to run at 800mhz till i reach 80% cpu load then bump to 1ghz. I never have my phone shutter or lag. The GPU is a monster. I get sooo much more battery life out of it. Overclocking is nearly pointless as a daily driver on this phone. In the past with my HTC Eris and HTC Evo 4g i had to overclock as muCh as possibly due to lack of a powerfull CPU and GPU but this phone (just like iPhone) has more than enough muscle and should be under clock 200mhz with no ill effect at all. Thia phone truely is the first legit android device in my eyes because it has more than enough under the hood. Underclock 200mhz and undervolt -75 and this phone truely shines and comes out #1 phone today in ALL areas. Smoothest scroling, lagless and best battery life to date. I love this phone and my set up

Ahhh big wall of text hates!

T989 turns off at random times..

hey all, couldnt search forums since its disabled. so like my title says, my phone turns off whenever. the samsung logo comes up and turns off. it happens every so often but nothing annoying. to get it back on is either take battery out or plug to charger and turn it on. when i did this, it gave me the searching for battery thing. this leads me to believe it could be battery? it happens whether the battery is 90% or 20%. anybody have this problem? my phone is rooted using juggs 5.0. phone is just over a month old so wonder if i can get a replacement battery to ruled that one? thanks for the help..

Mines does the same thing except it only reboot when its on charge, and all my contacts dissapear

@OP: Try flashing a different ROM.
Juggernaut has pretty aggressive UVing that not all phones might like.

It happened to me just today. I tried opening Facebook and for whatever reason it FCed. So I reopened it and my phone just turned off. I had to hold the power button for 15 seconds before I felt a vibration and it was alive again. Not sure what the issue is but it's safe to say you're not the only one experiencing this

Random reboots are usually a sign of too aggressive of undervolting. If it's not happening under heavy CPU load and is just happening during standby/sleep phases, then you're just barely on the edge of too much undervolting. Download system tuner from the market and go to voltages in the main menu then knock up the voltage one step (+12.5mV). You should be fine then.
For reference, you can compare your voltages to this list of stock voltages to see what Jugs' global undervolt is. I'm not too familiar with Jugs v5.0:

cool. I give this a try. The last time it turned off was right after I used gps. yesterday I was just browsing. thanks again.

Are you overclocking? If so what freqs/governor? Mine would do this when I would clock it too high for too long. May be an undervolting problem as well.

Your overclocking issue is actually still an undervolting issue. Your phone would reboot after overclocking for long periods of time because the processor wasn't getting supplied enough voltages for those higher clock speeds.
Undervolting isn't a linear process: if you run a global -50mV undervolt and cap your processor at 1.5Ghz, that doesn't mean that you can run a -50mV undervolt at a 1.8Ghz cap. For example, I'm currently undervolted -112.5mV at 1.35Ghz but if I bump my processor to 1.8Ghz, my phone reboots immediately because -112.5mV for 1.8Ghz is way too big of an undervolt.

Thanks for the clarification. I've not really dabbled in undervolting much, and haven't been too concerned with overclocking since the ol' mt3g days. I'm definitely going to read more about it. I've found that for my s2, stock kernel w/ stock frequency set and governor have worked best. Every device is different they say. Thanks your way for the knowledge. Always appreciated.

[ROM Custom] Overclock

Gello guys,
(I'm on MooDed ICS 1.0.2)
I wanted to know what kernel(s) is (are) the best to overclock the Arc and to what frequency can I go with the phone stable? I'm actually on InFamous Kernel ( http://forum.xda-developers.com/showthread.php?t=1843532 ) But I'm not overclock. I was before on DooM Kernel and overclock to 1.2 gh/z.
Thanks a lot! (And sorry for my bad English, I do my best)

It all depends on your phone. Even though there all made the same, some of the processors can not handle the same amount of OC as other do. The way to test which runs most stable is to slowly up the frequency every hour or so, and test it to see if it's stable.
If your phone starts to random reboot, then it's probably best that you choose the lower frequency to what you are using when it reboots.
I'm using inFamous Kernel too, its overclocked to 1.5.
1.4 should be theoretically safe as that the speed that the Arc S runs at with the same processor
EDIT: I don't recommend passing 1.5 on the Arc as it will very quickly burn out the processor. (Even at 1.5, it's running 50% more than what it was originally designed for).
Overclocking will also reduce your battery life. So it's swings and roundabouts depending on if you want performance or battery life.
Hope I helped

Over cloking is realy affect to battery life and all so the head will get increase,
am always usting 1.2Hz.i think it is enough to have a smoooth run for a xperia smart phone while saving the battery and reducing the risk

Ok thanks guys! I'll try all I can. I'm now overclocked to 1.2 ghz and battery life is good for me, because I recharge it all night. At 1.4 ghz, it's stable normally but the CPU is hot (very hot) and I don't want to burn it. But is it normal? Because Arc S is on this frequency and isn't normally so hot
So Thanks one more time!

Yeah, don't worry about it getting warm. If it gets really hot, then I'd recommend to stop using it for a while. Simply to let it cool down.
Mine can get to the point when it feels it's going to melt the plastic on the back yet it still works perfectly, so yeah i'd say its normal. There's also a ton of older threads about how much peoples arc's heat up when it's being used.
The reason why the processor gets so hot is because there is very little heat sink because of how thin the arc is.
Obviously the more you overclock the hotter the processor will get. The hotter the processor gets, the more quickly the CPU will burn out. If you don't like to replace your phone every few years, don't overclock it to the limit.

You should OC stable at 1.2 - 1.4 GHZ

Ah ok thanks.. I like to change it every year / 2 years. And now I'll try Puissant phone like GS3 and others.
I've overclocked it to 1.6 and it's stable (fast..) and hot. But I'll follow your advices. Thanks a lot!

dont overclock over 1.4Ghz if you have arc and you can always undervolt to save some battery juice

Ok, but I didn't find thé option to undervolt where is it?
Thanks

U need apps for undervolting such as setxperia, voltage control, etc.. Reduce the voltage and test it for few mins then again lower the value until ur phone auto restarts. Tats the threshold value

yea obv..undervolting means supplying less voltage to the cpu at specific frequency. it doesnt matter at wat frequency the phone is running

It might work fine well above 1.4 depending on the quality of the CPU you have in your device. I am fortunate enough to be able to overclock an xperia arc to 1.8 GHz and have been running at this clock for 6 months. Even gaming at lengthy time with charger plugged in works fine.
I do not game every day and just listening to music, talking on the phone, texting, reading a webpage or watching a video will not run the CPU at full speed all the time. Battery live if also fine for my usage 1-3 days. I prefer a snappy and responsive phone.
Running at very high clock speeds is at your own risc, the cpu chip design should be able to handle the high temperatures. I have allways overclocked my phones and have not yet been able to kill any of them, maybe I have just been lucky. There could be a poor soldering that breaks when it heats up, only push it to the limits if you can afford paying for a new phone

[Q] Has anyone ever underclocked One X?

So I tried to underclock my One X to around 640 MHz and it was running VERY smoothly and stable with only 2 cores active. I was using the ViperX 2.2.1 ROM and the Kernel was the no OC NCX 0.99a. The battery life wasn't bad, but has anyone tried underclocking to 1 GHz or lower? If so, how is the battery life and what kernel and ROM did you use?

With SetCPU you can change the max. CPU, but why should you? When the phone doesn't need much processor power, it just scales down by itself.
So, it already has the best underclocker there is.
Mayby you could try undervolting to save even more battery, but that means the CPU can be somewhat less steady.

im trying to get my head around UVing / UCing my HOX. is there any guide around? im trying to search through the forum but still no luck.

underclocking means the CPU runs slower so should use less battery but slower CPU speeds also means to takes longer to preform tasks which could use more battery, check on google most places say its not worth it as that battery saved is tiny and not worth the drop in CPU performance.
undervolting however lowers the voltage that CPU uses while working this does save power and also lowers heat (less voltage less heat) but if you lower it to much then the CPU becomes unstable due to lack of power and well crashes and restarts the phone in most cases.
to get the best out of undervolting you need to lock the max CPU speed to each step (CPU speed, 300mhz, 600mhz and so on) and slower the voltage and then run a bench mark (like antutu) and see if its stable, if it is you lower the voltage again and repeat until it crashes at which point you have found the lowest voltage that the clock speed can handle so you jump up a voltage then more on to the next speed.
it takes along time but that would get you the best undervolt your phone and hardware could handle.
or you can just use the global to lower the voltage for every speed, this is much faster and much less time consuming but you don't get the most out of it.
for this you basically drop the voltage then use your phone for different things; browsing, games, benchmark and see if it crashes if not lower again till it does then go back up a step.

thanks for explaining. I'm getting some of the points that I missed Awhile ago. I guess I'm going to try the longer way of doing it.
