Setcpu

Is anyone using setcpu? I bought it back when I had the hero but I'm not sure if it will work now on this phone. I'm rooted using toast's method if that even matters for something like this. thanks in advance!

It's the same CPU as the Nexus and it has settings for the Nexus, so in theory it should work. I had a Nexus before this phone and it worked fine.

I believe, like the Hero, you need a kernel tweak to have true overclocking.

yeah I dont wanna overclock i just want to downclock when the screen is off to save battery. I tried using the nexus one settings but it didnt seem like it was working using on demand. The clock speeds it was showing were kind of goofy. Guess i should wait for the programmer to update it

what?!? what do you mean u dont want to oc... theres always room for more speed!

true that but i have always been nervous about burning up the processor hehe

Overclocking would be nice, but I'd also like to save some battery with the on demand profile. Does anyone have it working?

I posted a patch in a thread in the development forum that would enable full support, plus overclocking, but nobody seems to have noticed it.
I might have to buy an EVO just to compile and test kernels... Or, if anybody wants to help me, shoot me a PM.

I used the unrevoked method to root and picked the N1 for the device in setcpu and it seems to be working great with the on demand setting. I have noticed a nice increase in battery life so far.

Is it linked or built-in?
If it's linked I'd be more than happy to test!

yea i use 1.5.4 pro edition... i make it go to 245mhz while idle/sleep... it works perfectly... and it runs 'ondemand'... if you dont need speed it wont go... i keep it to start at boot, and have ATK to ignore it so it doesnt close... theres no lag btw when it moves back to 998mhz

[Q] SetCPU on stock kernal, anyone have results?

I really do not want to flash a new rom/kernal.
Has anyone used SetCPU on their stock kernal? SetCPU now has that perflock disabler that automatically activates on start-up. I was wondering if anyone can post results that they have had with SetCPU and the stock kernal.
Thanks.

doesnt matter it doesnt work on stock kernels from what i know....
as i understand it you still need a oc enabled kernel.
you can underclock i think right.. but not overclock.
again i think.
but i dont oc... havs...undervolting.. it doesnt matter. you just destroy battery life when you oc the phone.

Why don't you just try it yourself? I don't mean for that to sound condescending or anything, I'm just curious why you wouldn't just take 2 mins to try it yourself.

There was a pretty big thread about this on ppcgeeks a while back when the Evo first came out and no custom kernels were around. Back then, it had no impact because the kernel didn't support it like the custom ones do. However, there were some that swore it did (placebo effect).
EDIT: I haven't read the thread with the newer RUU releases, so it might be possible now if HTC built support in the kernel. As mentioned above, give it a try and see how it works for you.

Because by the time I can see results, 24 hours would have already passed and I lose out on my refund if it doesn't work.
But, I am going to give it a try, screw it. I've spend $2 on stupider things. I'll report back after I have had ample time to test it with the Perflock off function.

SetCPU works just fine for setting the CPU on a stock kernel. You just can not overclock. And I don't know why everyone is so obsessed with overclocking. I mean it is 12% or 13% at best which isn't a lot. IMHO. And the drain on already poor battery life isn't worth it. 1Ghz is plenty fast enough. However, underclocking is a great thing.

Is it worth overclocking and undervolting Sprints galaxy s 2?

Running EL29 Odexed Blue Rom with EL26 stock kernal.
Just came from eVo 4G and have no idea if its worth it and if so what setting.
Any advice would be appreciated.

I've not done the undervolting yet but I'm thinking about it just still reading on what I want to do. I did however do the overclocks for a few days and imo only I really saw no need for it from the stock settings so I just went back to normal. The phone is fast enough for me even playing games that extra 1-2-3-400 mhz really didn't show that much of a difference.
Again this is my opinion others see the need for it I just didn't.

Thanks for you're opinion. Let me know how the undervolting goes if you decide to do it.. I wonder if vipermod would work with this device. I had it with my evo and it was pretty easy to use.

I think viper mad some stuff for the phone. I know he has a rom out for the phone already so maybe his tweaks are there you could always check the dev section.

My phone had freezing issues at anything higher than 1.4ghz, but even then the only real difference I saw was quadrant scores. Games ran the same, in fact I think the UI actually was choppier when OC'ed. Never really looked into it much though.
I don't even know why I tried it in the first place, I never said to myself "gee, this could be faster.." I guess coming from an HTC Hero it was a habit.

this phone does NOT need to be over clocked; it is so much faster than your Evo, that you won't believe it!
Undervolting and under clocking can give you extra battery life; do a search on the Dev thread, and you will learn lots about it..

2.1Ghz Overclock like on HTC One XL

Hey guy's I noticed the one xl just got kernel sources recently and the result? Insane oc! I was just wondering how hard it would be to match the 2.1 frequency on the galaxy s3 lte as they both run Qualcomm s4's.
Sent from my SGH-I747 using xda app-developers app

The 1.9Ghz we currently have isn't enough for you? !!

Ahaha, well the thing is I returned my one xl for a galaxy s3 for performance reasons. I love to get every bit of power I can from my device and I somewhat expected the s4 to hit the 2ghz barrier soon after it was fiddled with. Battery drain is not a deal breaker for me.
Sent from my SGH-I747 using xda app-developers app

2.1 ghz.... My device runs butter smooth on stock... Will 2.1 cause it to melt like microwaved butter??

From what I heard mildly hot these s4's can handle it though.

Depends the phone is quite new give it like 2 or 4 weeks tops. Right now IMO development is kinda slow.

is overclocking a phone anything like overclocking a PC? I've never Oc'd a phone before but have plenty of experience on PC.

Way more simpler actually.An app shows you your available frequencies choose the one you want and done.Oh and its live OC to.

Overclocking a phone is not easier than overclocking a PC.
Phones have many CPU steps so you have to find the right voltage for each step.
Also you can only change CPU voltage and frequency. (Some kernels allow you to change bus speed which is nice but alot don't support this.)
The only sensor you have is battery temp.
Furthermore, when overclocking a pc, you can just run prime95 for 10 hours and you know your stable. With the phone there is no difinitive stability test so sometimes something might trigger an instability afte you have been "stable" for a while.
Also no third party cooling. (As far as I know)
Im not saying it's really hard, but honestly when you come from PC overclocking you will probobly get frustrated about some things.
All that being said, overclocking a phone is super fun and I hope I didn't scare you away from it in any way.

Am I the only one who isnt interested in overclocking in the least bit? I mean, the damn thing is fast enough already. I can understand overclocking something old like a nexus one, but wow. What do you guys get out of OC? What do you use OC for that requires the higher speeds?

If you have to ask this then don't worry about it. The average PC doesn't need more than 1ghz. We overclock because we can!

I custom built my computer, im sure i can overclock it to who knows what but it being so new i don't even think about it. Maybe in 2 years when it starts showing age.

Most people that overclock their PC will get a new one before they really need the speed anyway. It's just because its is fun. And plus if you know how to overclock, there is really no reason not to. It's not like it's a trade off, its just free performance.

gotcha, i wasnt meaning to be disrespectful, i just never understood it unless needed.

You should try overclocking your PC. You might find that it is very fun.

I said simpler because in my experience I just select the frequency that I want and it causes no stability issues and under volt each step by 25mv.

Your right about that. If your not pushing it to it's limits its easy. But then again the same could be said for PCs.

Ktoon's KT747 2/8/13 Kernel vs Task650's 2/10/13 Kernel

What are your guys' opinions on the performance of these two kernels? From what I've gathered it seems like KToon's kernel is meant for overclocking, but then what would one use task's for?
Task's recent update to his kernel makes me want to try it because I've been using KToon's kernel with the ktoonservative governer and row scheduler UV'ed a little bit but unlocked to 2.1GHz and have been having some pretty bad battery life in mu opinion, do you think switching to task's kernel would be better on the battery?
Well what do you guys think?

Fun Fact for the day. Versus threads get shut down in no time here on XDA.
P.S- Why wouldn't you just try it first before making a thread about it? Kernels take about 3 seconds to flash. Also. No one can tell you that you will get better battery life on one or the other considering all of the variables. We are all in different locations, use different apps, have different settings, and we all use our devices differently. You need to try them both out and see which one works better for YOUR device.

Man why are ya giving me a hard time? You kicked me out of your thread, which I understood and respect, but then you come here and tell me the same thing you told me before and that my thread's gonna go to the bin in no time.
I'm just trying to find out what the DIFFERENCES between the kernels are, because it isn't very clear in reading the descriptions/OP's,
They wouldn't co-exist if they were exactly the same.
I'm not too interested in tweaking the hell out of my device nor do I care too much about overclocking...I just want a lot of screen time and the ability to play games and SMS with little lag.
I have tried out both kernels and didn't really notice much difference because I didn't really know what to look for.
Like, okay or example, it seems to me that your kernel is less for tweaking and isn't for overclocking (max 1.6GHz or something?) while KToons can go to 2.1.

I'm not giving you are hard time. I'm just telling you the facts here. If you're not into tweaking and messing with things then this is simple and really shouldn't make a difference to you which one you use other than battery life, less lag, ect... Which no one can tell you one is better than the other for. Flash one and don't touch the settings for it and use it how you normally would for a day or two. Then do the same for the other kernel. See which one gets you the best results. Its the only way to find out. Not quite sure why you're refusing to take my advice here. Its pretty straight forward.
There's kernel source in both threads that explain in DETAIL all the DIFFERENCES between the two. It literally only takes seconds to flash and see for yourself. This shouldn't be a big deal at all.

I think they re two of the same.Task just doesnt want KT to know he borrowed his kernel...lol jk. But seriously,they're pretty similar.KT seems better on the performance end but I never got the exceptional battery stats that ppl keep posting,IdK it may be something on my end. On the other hand, task's seemed better on my battery as I could not noticeably see my battery drain during use as I did on Kt's. Furthermore my phone does get hot really fast on task kernel,I'm guessing its cuz we use performance control and can't really play in the voltages as much.

I have flashed both kernels. And I don't mean that I am not planning on doing ANY tweaking whatsoever, I just don't mean like messing with voltages adding or subtracting 25 at a time until my CPU crashes so I can find the under/overclock limit...that's the kind of tweaking I have no interest in trying. I'm not gonna look through he sources of both kernels, come on dude you know I'm not a dev and that level of detail is un-necessary.
Your kernel being capped at 1.6GHz probably is better on battery but I also have a sixaxis controller and like to game, does it affect 3D performance at all?

This is the kind of posts I'm looking for in this thread. Do you personally find task's kernel's performance to be any worse than KT's? Cause you said bettery life seemed better.
Also, are the same governers and I/O schedules available between both kernels? The only settings I'm used to using is ktoonservative and row, I wouldn't really know what to do in performance control to emulate what I've done in KTweaker.

He cannot answer this question honestly. He doesn't have your device. You're not understanding. He can have the best battery life possible on my kernel but if you use it, you could have the worst battery life possible. IT'S DEVICE DEPENDENT. Will you please just do yourself a favor and take 3 seconds, flash the kernel, and see. You say you've tried them both, but you are also asking about playing games and what not with them? You would know if you had tried them dude. Same goes for the governors & schedulers. You would also know that if you had actually tried them both. I need to ask you this. Why won't you just try them and see for yourself. Are you really the type of person to flash what people tell you to your expensive device?
Look dude. I'm only trying to help you here. I'm not quite sure why you wouldn't just take my advice here. I have quite a bit of experience with this stuff and I'm trying to help you get the best experience possible. But it seems as though you think that personal opinions of others are whats best for your device when in all reality they are not. Real life testing is what will prove to be best for your device. Trust me.

What You won't have on underwear kernel vs kt747: ktoonservative gov, vibration strength control, screen off max freq control, screen off gov control, fast charge, MHz range from 96 to 2106, undervolting capabilities and adjustments to governors and schedulers.
If you don't want to undervolt or tweak anything, I recommend you use underwear kernel. It is stable fast and oc to 1674mhz is alright for any gaming and it doesn't affect 3d performance.
If you wanna use ktoonservative governor then you will have no choice but to use kt747.
But anyway, what you really need is to try both and familiarize yourself with their features.

Thanks everybody for their input, if anyone else has anything to say then please go for it!
Wiping cache + dalvik and flashing underwear kernel then fixing permissions and rebooting and gonna take a look around performance control to see whats up.
