Stock vs Overclocked

Is it worth rooting my phone and overclocking it?
Is overclocking it really noticable in performance to say approx 1.5GHz? And is it going to kill battery? Thanks

Yes and Yes to both of your questions. There is a noticeable diffrence in performance when overclocking. But it will obviously use more battery

cant say ive noticed 1.5ghz killing my battery.. might be used a bit faster.. but u can easily offset this by lowering your clockspeed and voltage for your sleep state in addition to minimising the required voltage that 1.5ghz requires, id say my battery life is probably better overall, and i run 1.5ghz 24/7.
of course your mileage may vary depending on usage and various settings.

How hard is it to overclock it? My phone is rooted but I have no experience with overclocking.
I'm guessing it wouldn't be a wise idea?

Yeah this seems a little over my head.. thinking of buying another Xperia Play just to mod the crap out of.
Dont really wanna mess with the overlocking now I think about it incase I fry the chips and kill the phone.

At 1.4 and 1.5ghz its quite safe.
To chill out the battery put some screen off underclocking like at Real low with but not the least
1. 4 ghz scaling interactiveX I get 252/282 MS, thats pretty fast with nitro lag Nullifier too

i currently overclocking my play to 1.6ghz and it runs fine.. games and apps run a lot more quicker

i'm quite interested in overclocking.. been thinking about it for the last months..
but i don't know, 1GHz is quite enough for me.. im not experiencing any slow down..

Well with 1.5Ghz then, you'll be amazed!

SetCPU, What are your settings?

Anyone try SetCPU after rooting? I can adjust the min down to 192mhz. Anyone have any idea how safe it is yet as far as sleep of death?
Sorry if this is not in the correct forum

You can test whatever you'd like. I tried it too so just don't check the option for set at boot.

Just worried since it is my alarm clock too, a sleep of death could lead to a sleep of no job

i believe there was something about needing a custom kernel that supports a cpu oc app. something about it not engaging both cores... just one of them. somebody out there knows more than me about this i'm sure.

I think i remember dsexton702 talkin about needing a kernel for tegrak to function properly

Tegrak probably won't work properly if I'm correct set cpu or oc/uv beater should be fine. Tegrak was used for samsung processors. Qualcomm processors are able to scale better at lower or higher frequencies.

It will never engage both cores that is asynchronous. Both processors work independently from each other. This is why you see lag. Both processors are never at their full potential. Qualcomm design the processors for best battery life in mind with good performance. There is a way to get both cores to be synchronized though if it matters to you. But expect worst battery life.

The one we have should also overclock very nicely. The APQ8060 is the same one in the Touchpad and that one easily does 1.9Ghz.

When I installed setcpu and had it auto dectect speeds It atuomatically set the min at the max and the min at the highest clock speed. Is that normal? Did anyone else notice that?

Yes. But you would need a kernel that supports Overclocking and Undervolting.

Undervolting//how low can your phone go :D

just a little information/ competition to see which SGS2 is the best , i want to see how low of a voltage you can go. I am using Stability test to test out the voltage, 3 round of classic test at 1.73ghz at 1125mV, and it stable, a little scare to go down more but here some info on my SGS2
running
beastmod 4.2
kernel 2.3.6
Was running originally at 1175 but i undervolt to 1125 and running stable at a stable temp of 41-42..
what's yours

be careful with such drastic undervolting at those frequencies, could result in corrupt nand.

This isn't undrevolting..... this is underclocking.
Undervolting is pretty dangerous with trial and error. The lowest I'll go is -75.

no underclocking meaning i would use less ghz than the stock, this is minimizing the voltage on the core.
what your doing is underclock, i put mine fixed on 1.73ghz at 1125mV of voltage

I have never heard of such thing, i'm not doubting you but from over the years, i heard undervolting have positive affect on the CPU by lowering temp and give battery more juice.
where did you get those facts from?

As far as I know, there are no dangers associated with undervolting. I run at those frequencies too at -112.5 and have never had a problem of any sort.

I run about 1ghz. No under volt with this ics kernel but with my old gb kernel I undervilted with faux -100 at 1ghz...ran cool even with games and video, great battery life. And honestly 1ghz is plenty for snappy fast speed

I don't know if you're familiar with overclocking, but the same type of stability issues can occur. When you're undervolting you can think of your stock speed as an "overclock" and you're just trying to minimize the voltage necessary for stability. If you undervolt too much you can experience freezing, corruption, bad lag, etc. It's all the same process for desktop computers, laptops, and anything else you can play with the voltage.
Personally I'm at -62.5, but after seeing how low people are going I might be a bit more adventurous. Don't use the "Set at Boot" option when you're experimenting.

I did it gradually...and the fact that I was at 1ghz might have also made it possible. Started at -50 since most had said it was safe...then tried 60 then 75 then 90 then maxed at 100...worked beautifully.
I have heard and it is true that phones are made very different. Some exact same models can't oc or UV as high or low as others...I got lucky with a really good model...my old nexus S couldn't oc to 1.4 without freezing while others could.

Right, I meant that there are no risks to undervolting in terms of physical damage to your phone, only stability issues which is fixed with a reboot, assuming you didn't set at boot. Overclocking is a bit different in that the risk overclocking presents in addition to stability issues is the risk of overheating which can permanently damage your phone. Undervolting can compensate for this somewhat by letting the power supplied to the processor and thus reducing the risk of overheat.

I use system tuner, you can also look for Gideons script that is flashable in cwm to undervolt.

Im undervolted to -75mv for quite some time running a script clocked at 1.518min384

It's more based on how the rom works, and the kernel yes helps with CPU and GPU scores but I noticed his GPU scores are lower than mine, one of the nation reasons I'm still stock. Because it's probably persues kernel and has issues with FPS in real world and quadrant performance.
He probably ran it 1600/1600 on performance or something on those lines
Edit: this is mine stock rooted GPU much better than his, until persues can match this without overclocking the GPU just to get the same performance I do on stock I'm not switching.

Maybe you should consider that you're not the brightest, most experienced person in this thread before talking smack.
Exposing a component to more heat means you are shortening its life, there is no doubt about that. Those with overclocked desktop CPUs often have elaborate setups with overclocking in mind. You can't add a better heatsink, or a fan to your phone. Mobile CPUs, especially, are designed to be efficient at a certain range of clock frequencies. Moving it too far from the norm means you eventually see diminishing returns.
I've fried everything from my first Commodore 64 to my current box, and everything in between. If you think the phone can function at that level for an extended period of time without failure, best of luck to you.

Dude it was part of the whole meaning of rooting and tweaking. Checking different settings for a little bit, testing them and then reverting back to defaults. I will never leave overclocked/ undervolted or vice-versa settings for a whole day... its just part of the fun of tweaking and experimenting with our devices...
Sent from my GT-N7100 using xda app-developers app

I am all for overclocking, modding, tweaking, hacking, etc. Breaking **** is the best way to learn. But that doesn't mean you should push your hardware past the point of exponentially diminishing returns, and increased risk of burning your chips out. That is, unless, you have no problem with the very real possibility that you'll need to buy a new phone.
That being said, kudos on "going plaid" with your Quadrant score

Its the Redpill v1.42... I prefer it compared to all the others i used ( stock, perseus, n.e.a.k., note2core). Those results were with stock rom but redpill kernel.

Overclocking and undervolting CPU/GPU

Ok, so I'm currently unhappy with my battery life. I used to underclock the CPU on my HTC Evo but im not sure how to do this on the S3 i found a guide under the I9300 for this but i need to know if it is usable for our device as well. Also, curious as to how overclocking the GPU affects battery life. Is it the same as overclocking the CPU or is there little to no change? Also i want to know the most common voltages used as well
