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.
I need a link to a tutorial for the epic 4G please.
Can anyone explain in a couple of sentences why undervolting is good? Does it save battery life? If so, how much?
Also, how much of an improvement are you getting in tasks like playing and recording video from overclocking? What functions of the phone benefit the most and are there any battery-life effects from it?
Thanks

Improvements are small, but everything counts - bad analogy > 10volts uses more electricity than 9volts - if you could make your CPU run at 1ghz with 9volts instead of 10volts, you would be saving electricity, ie battery.
With that being said, lets say CPU's from the factory can run at 1ghz at 10volts plus or minus 1volt, but they set it at 10 volts because they know it will run safely, even though it could run at 1ghz with 9volts. But not all CPU's are created equal - so similar 1ghz CPU from the factory will have some variance. Some 1ghz CPU's instead of saying they run at 10volts plus or minus 1volt, they may have a specification of running a 1ghz CPU at 10volts plus or minus 1/2 a volt - that's why when some people try and undervolt to much, their phone might lock up - and then there are 1ghz CPU's that can't undervolt at all and must always have 10volts to even run.
Over simplified, but you should get the idea.
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!
im now using a custom rom with the overclock kernel... i set my phone to "1.4ghz" with AnTuTu... its working great now... no more fps lags on the games i play... and no crashes... im just curious about one thing? will it break the phone in any way? its not heating up or anything atm... i mean i have experienced phone heat on my sensation xe... that phone gets really hot STOCK....
i dont want to break my play... i really like it compared to other phones in the market right now(the only one with gamepads)... its my first time ocing a phone btw...
If its not noticably hot (the battery too) constantly then your fine, just bare in mind try not to push it past 1.6ghz i found my phone didnt last very long at that speed.
The only thing with oc its that it shortens the life of your cpu obviously depending on how much you oc it....and it drains more battery but its not that big of a deal

what do you mean by it didnt last very long? did it break the phone?
Basically, my phone is overclocked to 2.0 GHz with smartass scaling with max 800MHz interactive scaling when screen turned off. It works great! Lasts 2~3 days without gaming (5 to 7 days with airplane mode on) and 4~8 hours of hardcore gaming with full charge (6~12 with airplane mode on). I recommend using an extended battery (I haven't, yet) if you are doing so. And it also involves luck. Even if it is the same model, color, etc. some CPUs are more capable than others.
still testing my phone under 1.4ghz seems stable...

is it normal for the phone to be abit hotter than when it was running stock???
btw how does smartass compare to ondemand?? smartass tends to get lower benchmark scores than on demand

Yes ofc its normal - as each CPU/GPU creates heat based on the load it takes....
So the higher u OC the hotter it gets - thats why in former days OC was quite dangerous
In todays times cpu normaly 1st get unstable, and then has a safety function to shutdown if it gets too hot. (no warrenty that its the same for all chips)
smartass doesnt switch frequencies at once like on demand (e.g. instant from 200mhz to 1000mhz) but it tries to predict the needed power somehow so the whole switching is done in more steps... (as far as I remember)
So yes its performace is a bit below the on demand - but should not be that noticable - but it will also save your battery.
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
1,6 GHz on XArc by Sirkay = epic speed.
