Why overclock?? - Android Software/Hacking General [Developers Only]

Hi people. Im new to forums in general so try to use small words lol.
Can someone explain whats the reason behind overclocking a phone?? Ive underclocked my galaxy s down to 800mhz to save battery and you only notice when i have a few apps running which i never do anyway. Im not dissing anyone who does, id just like to know.
If theres a guide covering it ive missed please post it and ill read up

Unfortunately it is impossible поницить frequency of the processor

Speed increase.
It is useful for applications the require more grunt.
If you want to understand it use psx4droid to play a game at 1.2GHz then at 800MHz

I like everything to be snappy on my phone. Overclocking my desire from 1ghz to 1.25 makes it cruise!

I think the SGS is fast enough and you can play all the games available without lags. So overclocking is just for fun, but in normal use you don't see any difference.

how fast do you want your phone?

I overclock to 1.3ghz on my epic 4g when I use emulators and when I am not far from a charger but other than that I generally scale down to 800mhz

I have the HTC Aria, a little 3.2" Android powerhouse, dev-friendly device severely throttled by it's 600mHz processor. So I overclock it, and this little beast lives up to it's potential. It's like having a superphone in a small size. That's why overclock.

Got my Nexus One @ 1113, but really it's just force of habit. Trying to eke out a little extra performance and all that. Can't say i've noticed any difference though!

Overclocking my ZTE Blade to 729mhz (600mhz stock) can play most of HD games (...Gameloft's especially) without lagging......
I think overclocking is only for gaming purposes ... ♫
▲▼▲Overclocking → The worst battery killer▲▼▲

I have a feeling most phone overclockers are getting a placebo effect.
If you were to hand them a phone and tell them it was 800mhz, they'd feel like it was slower than if you handed the same phone (unchanged) and tell them it was 1.2ghz.

Mobile phone companies configure thier devices for maximum age. However overclockers push limits beyond stock. With right procedures, you get upto 50% speed boost resulting stunning output. Just your cell phone will die early :/. But not that soon. I am using DHD. Overclocked to 1.53ghz ( stock 1024mhz ). Rest, you can reckon.

How come some phones get high quadrant scores?

Hey
I overclocked my Galaxy S and I did some tests in quadrant to see if my clock gave me lower performance.. Anyways I got 2950 as my best score @ 1.5 GHz but I see some HD2's getting 4400 in socre @ 1.5 GHz. I thougt my Galaxy S would get a better score then a HD2. Is it becouse the HD2 running a slimmer rom with less background processes or are they just lying?
I believe quadrant scores are heavily varying and dependent on the device, and for the most part, do very little to reflect "real" performance.
I don't have a straight answer, but I wouldn't worry about it too much. Your scores are still magnitude's higher than my Hero, my absolute highest (with unsafe tweaks to the clock and kernel) was about roughly 500

Overclocking is just ramping up the processor in your CPU to higher frequencies for faster performance. There are limits, you can't go too high because you risk damage and overheating, and going too low can cause severe slowdowns and instability.
BUt finding a sweet spot for the minimum and maximum processor speed can result in a much faster phone when the screen is on and a way better battery life with the screen off.
nice.... n thanx.... how did it works.... is there any soft stuff(app) available for it or somethin else....????

Ah...Good old days!
Anyways,there are many many ways to cheat quadrant.Running the app from a ramdisk,patching SQlite,running a rom from SD(I think) all boost the scores.That is,however,because Quadrant relies heavily on I/O,which gives unreal scores.Remove I/O benchmarking from the test and you have a helluva accurate benchmark.Pretty good too.
But on the SGS,let me make my guess.Are you running Cognition rom?If yes,are you using interactive governor?Again,if yes,switch to performance governor and yay,4000+ points in Quadrant!

Unfortunately, it requires a custom kernel, which in turn requires a custom recovery (and in some cases, a custom ROM) to achieve.
ohhh crap!!!! thats the reason i want a forum or some dev to create interest in my device..... hey can u tell me somethin j shud do....????

Im using CM7 with Glitch kernel. And I used "smartass" when I got the score but now I get like 2470 in score now even with performance. Plugged in the charger and now I got 2888 in score so I guess the charger helps a lot in quadrant to..

Cannot agree more. It sure is fun showing around your quadrant score but a quadrant score never reflects true real world performance. Maybe, Neocore would be a better benchmark but then again non of these benchmarks would show how fast apps could load or how smooth you switch between apps.
I use an LG GT540 Optimus. I was able to reach 64.3fps on neocore and 1250 on quadrant after overclocking to some 800MHz with performance controller.
Quadrant also doesn't reflect the core memory/cpu usage. ie Sense UI eats more resources than vanilla. So, same phone running vanilla and sense will have different scores.
I believe Samsung uses TouchWiz. Perhaps, you could score better with a vanilla rom or cyanogenmod.
Last but not the least, Quadrant scores could be faked just as easy as you could fake version numbers in About Phone.

OC Max!

Hi Guys I have a Galaxy S 4G I have noticed that max stable overlclock is 1.508Ghz If I bump up to 1.516Ghz It is stable but at watching videos for a long time it crashes, I have noticed that the normal max temp is below 60 C or 55 C, that's stress testing for long time, normal everyday is 41~43 or, I Think It can go higher but I t would need 1500mV or 1600mV core Voltage also to achieve 1.6, 1.7 or 1.8 even 2.0Ghz It takes 1600mV or 1800mV, temps would be 45~47 normal, and above 60~65 on stress testing. But tegrak doesn't support these volatges, It would need to tweak the code. With proper cooling temps can go down to 33 or 30, lets say using the phone in a cool room.
Do you know when are they gonna support higher core voltages(Tegrak OC)?
Do you really need to oc that high?

At 1.5 is goood but for proper PC like performance it would be a bit higher.
2.0ghz would beat samsung sgs2
I know anything higher than 2.0Ghz the phone would suffer, I don't know if the main board can support 2.5Ghz or 3.0Ghz. The battery doesn't handle that much power not even 3500mah battery
Mine runs stable and quite cool @ 1.62 and I get 4128 quad score, but I have no need to oc the phone with all the tweaks.

Thanks I'm gonna try out your setup, but that's the highest it can go?
I get a max of 2300+ because I have no tweaks and I am at Stock 2.3.5 UVUKJ3
I really don't see the need for oc other than for playing a REALLY graphical intensive game. For me, I get a better performance boost from the tweaks incorporated into roms than oc. I tried running a 1.5 for a week and I honestly didn't even notice a difference other than less battery life.

Well I notice a difference but anything above 2.0 GHz it is nearly impposible, even if it is gotten above that it would not match new dual and quad Core CPU because they have a different architecture but the battery is the first thing that you notice but the things that I do on the phone require much more processing power than stock. Well the highest is 1.6ish that I think the phone has been able to handle. But definitely overclocking the phone will get you up to speed work new games coming out

When we get source for GB or ics then I can write scripts to tweak the voltages higher for a higher oc, I have been waiting for that lol

[Q] OC - noob - should I go for it? Risks? Worth it?

Hi.
I a speed freak! If there is something I hate, is lag.
I therefore thought of using a better kernel for my G2x.
As I understand, some kernels can OC the cpu. Wow. That's cool, first of all.
Second - any conclusions about this? Is it safe? Does it really make a difference (i don't game on my G2x)?
THANKS!
Since you obviously don't know how to use the search function, I'll just tell you that it is perfectly safe to install a kernel and constantly run it at 1.5 Gh.
Go buy setcpu from the market to set your processor speed at Max, and leave it there. All the time. No matter what.

Haha, good answer..Or you can go and download CPU master for free. =)... But honestly overclocking is not good
There's no real speed difference when overclocking install a custom kernel but don't overclocking it its a waste of battery
Sent from my LG-P999 using XDA App
risks? yes. it kills your battery faster, and battery life will drop. by battery life, i mean the amount of recharge/discharge cycles it normally will allow will drop.
pros? makes your phone much faster. and no its not a placebo. if you bump up your kernel from 1ghz to 1.5ghz, thats obviously a speed increase. how can it not be faster.
Sent from my LG-P999 using xda premium
But also the risk at a constant 1.5 of overheating and burn out of the processor.
if you're a noob and don't know exactly what OC is, don't do that.
it can kill your battery and processor much faster, make you're phone unstable and accidentally overheat and burn out your processor, if you have a constant OC
processor life is worth the wait imo
I oc mine tops 1.2 and its as fast as it needs to be for my needs. I also bump up the minimal speed to about 500-800 cuz our g2x's should never be running that slow even when idle/screen off imo.

at the risk of offending you, I would not recommend setting your phone to 2ghz..I can assure you nothing great in the long term is going to happen. As for kernels give LordClockan and TalonAce a glance, I'm not 100% sure if they are 2ghz kernels but its a good jumping off point
2ghz will fry your CPU. Maybe not initially buy your phone will definitely fail prematurely. The only reasons other people do it is because they can and they probably have a newer phone for their daily. Even just overclocking a little bit can have a negative impact but not as drastic. If you insist on overclocking I wouldnt exceed 1.4.
With that said there are several Aosp kernels that will allow you to push it to the limit. Just search the dev forum.
Overclocking your cpu will not hurt it unless its running hotter than the cooling system can handle. It will cause lock ups and failure to boot. If you start overvolting it, you WILL cause premature damage to the chip itself. Optimum overclock has always been 10-20% increase for any processor. Personally id rather underclock and undervolt a little, runs cooler and less power drain.
gizmoe is right, 2ghz is a 'just cuz i can' overclock. it wont run stable at that level. its like the 8ghz overclocks you see on the intel processors using LN2 cooling lol.
2ghz is bad.
I ran my inspire at 2ghz and besides the battery practically counting down the phones was heating up and that was maybe 15 minutes. Definitely not a goods idea.
Thank you for the input and info guys.
I could over clock and undervolt on a past captivate. Is there any app you would recommended for the inspire on cm7 to do this?

Setcpu use to be the go to app but many found it to lag after waking the phone. Many have now moved on to daemon controller. From the looks of it you're using CM7 which has the function built in..I believe its menu > settings > CM settings > performance...or something like that...don't check set on boot until you know how much OC your phone can candle. If you like CM, take a look at Absolution by the Collective. They have scripts written for custom profiles for OC and UVing.

I've clocked to 2ghz a few times just to get a crazy quadrant score but that's about it. I usually keep mine somewhere in the 900mhz range with a little lite uv'ing and found that to be plenty.
2ghz can definitely be bad for your cpu..... Like to much bacon can be bad for your arteries.....

so what exactly does this do for the performance of your phone? Is it just apps opening up faster and games a little better?
I understand the performance gains in cpu overclocking for computers in that you get faster encoding for videos, maybe a few more fps in gaming etc but how noticeable is doing an overclock for your phone?
Is it more of a just because you can or is there a real benefit to the user that they can notice?
A 30% overclock on your PC might give you 10-15% better performance but does that equate to similar improvements with a moving to 1.5 or 1.78ghz on your phone?

It's a balance there is only so much you can get out of the CPU in anything once it passes the threshold you get less from it more heat less life we are at 1.2 default I would say after 2.0 we won't get much more but a dead battery is 3 hrs I got mine at 1.1 I am good with battery vs power consumption
