x10 uses ondemand cpu scaling 245 - 998 mhz stock, do not use setcpu

just wanted to let everyone know this, as there are still plenty of threads out there that suggest setcpu, and it's a waste of time

Thanks dan, where you been stranger?

so what does it mean? it's doing what setcpu does? what about battery and temperature profiles? what if i want to force the cpu to use a lower clock speed to conserve battery?

I never understood SetCPU myself. The CPU is only used when required, so creating all these settings likely does nothing.
I'd consider it for overclocking, if that was possible.

I was also informed that our phones should do this anyway but I was suspicious of how well it does, being on 1.6 and butchered by SE after all.. it made a good deal of difference before the update.
Trying it without the update now and we'll see how it goes. Completely removed it and power cycled. Will bump in a few days with my results.

I found android got extremely laggy on 1.6 with setcpu. and I use a temp/cpu widget to keep tabs on stock behavior, my cpu sits at 245 most of the time, except when I'm using the phone

What widget do you use?
I took a quick look on the Market and AppBrain, and couldn't find anything to track/plot CPU clock to see what the phone's doing while in standby.
I do use SystemPanel, but it doesn't plot CPU clock over time, only usage.

Try advanced task manager it shows cpu speed...

I'm not looking for a way to see the speed. SystemPanel will do that. I'm looking for a plot that shows the cpu speed over time, so I can see how and when it changes.

Try Usage Timelines Free or seepu++ (not free and dev seems to have abandoned it)
Edit: sorry I see you want clock speed not usage. I have yet to find an app for that as well.

so what is SetCPU doing then? draining the battery? or is it affecting the charging process?
and what about the app CoolS? its almost the same thing as SetCPU but the only thing you can do is slow the CPU down

You can use SetCPU to:
1. Overclock (but not on X10)
2. Underclock (you know you go somewhere for 2 days and forgot the charger at home)
3. Make profiles to lower CPU freq when temp is too high
For day by day use, i'm ok with android's ondemand scaling.

use android hackers apk. thereu can see theCPU over time...

i use setcpu to underclock my X10 to 5xx mhz when the screen is off.
my batt usage is better, from 3-5% per hour to below 2%.

I've been using overclock widget to keep it to 998mhz to see if it would make a difference in quadrant. Recently i uninstalled it and i still get about the same benchmark score.

anyone tried undervolting xperia play

Has anyone treid undervolting I used the setxperia its pretty useful i dnt know if it does undervolt or not does anyone know im using doomkernel latest

If you mean underclock then yes you can underclock using even the stock kernel. The only advantages you will get with underclocking is slightly better battery life but your phone will be slower.
I dont recommend underclocking your phone any lower than 800mhz, If you clock it any lower than that you will start to notice the slowness.

I'm undervolted pretty good, my 1.5 GHz runs at the stock 1GHz voltage (1200) it does help a little. The lower frequencies are where you're going to see better battery while your screens off.

Yea, I notice the most battery gain from when its sleeping with a setcpu profile to keep it at minimum mhz when the screen is off.

I think your all mixing underCLOCK and underVOLT, underCLOCK means you lower the clock speed below the stock clock making the phone consume less power, you can use SetCPU to do that
http://www.appbrain.com/app/setcpu-for-root-users/com.mhuang.overclocking
underVOLT is when you reduce the power to the CPU at various frequencies an app such as setxperia like the OP said or myrt undervolt can do that for you,
http://www.appbrain.com/app/myrt-undervolt-gui/com.myrt.myrtundervoltgui
This helps you save more power but can lead to shutdowns if you really reduce the power too much. So yeah, stop confusing the two, it's annoying

also you can use system tuner pro !
it can do all the options at once .

Me? No I'm not confused. I notice the most battery savings when I undervolt the lowest frequency and set the profile in setcpu to keep the frequency at the lowest possible. This is because your phone is sitting with the screen off 80%-90% of the time. I don't notice as much of a battery savings by undervolting higher frequencies but I'm sure its there.

My bad at least I learned something new

Undervolting's great, I've actually got my 1Ghz frequency running stable at voltage of 975 instead of 1200. In fact, that's the farthest drop I could get with any of the frequencies though (voltage of 950 almost works, but it's not friendly when booting)

It will definitely shorten the life of the battery. As for the phone itself I can't really say. I used to use my vibrant @ 1200mhz daily while running bionix 1.3.1. I never really noticed any wear and tear from the overclocking. If your phone runs warm while overclocking you should really consider running the stock voltages. Your phone may overheat and fry your cpu gpu with the high temperatures. So be careful when overclocking.

Meh i dont completely agree...
It will only shorter the life of your battery because the processor will draw about 20% more power which is very small compared to the like 20x more power the lcd takes up.. i dont think youll feel the difference.
The heating up i disagree with too since ive seen processors reach boiling point of water and continue to work.. thats not to say they all will but ive oced my phone to 1.6ghz to benchmark for several minutes and it never got above 41*... the battery heats up alot more when its charging than the processor does most of the time so i wouldnt worry tooo much about that.
Now as to whether the phones llife will lower... yes probably.. youre putting more stress on the processor than if you dont oc.. honestly tho, processors dont die very often so i oc all day as my daily runner, usually to 1.4ghz if my kernel will do it..
Up to you and honestly all of this is my opinion based on my available info etc.. hope this helps

Everything I have read says 1200 is completely safe. I run mine at 1460 with no issues. It obviously draws more battery but using Voltage control app you can adjust the level of battery.

You would be fine with 1.2Ghz, but look into a kernel that supports some slick CPU scalers (smartass is a good, easy choice). You can set that (1.2Ghz) as a max clock and you can let the scaler determine how it gets there (if need be). Running only 2 clocks (OC and deep sleep) seems a bit overkill to me, but to each their own.

Like everyone else said, you ought to be perfectly fine with that value.
The highest I would go is 1500 though

Lol, running an overclock on a phone seems a bit overkill to me...
Think about this.. How much copper is strapped up to your phones cpu?
Would you overclock your desktop on a stock cooler?

Galaxy S3 overclocking

Hello guys. I just want to take information that there are many tweaks to overclock galaxy s3 to max 1.8 ghz. If we set to maximum overclocking then is there any risk for damage hardware? Because 2 months before i had nokia n8 & i set this device to overclock & it damaged all board,now its totally destroyed. According to my point of view,sometime i think that nokia n8 has only 680 ghz & due to overclock it run on higher clock speed & so that due to low processor it could not manage or handle the higher clock speed & it ran on heavy clock speed continuesly then overload of processor it got damaged. It is my fear for s3. And i think for s3 that it has higher processor with 1.4 ghz,if i set it to 1.8 ghz then there is no risk bcoz of there are cpu governor. With this,the s3 does not run continues on 1.8 ghz higher speed, governor takes control over the cpu to run on higher clock speed according to their high usage like 200 ghz, 500ghz, 800 ghz, 1.4ghz & so on. So i think i can overclock my galaxy s3 with kernel but I'm still confused & I'm not expert. So plz suggest me to do overclock without any damage fear. Thanx a lot.

If i don't but you know then u can tell me about any risk.

NOTHING is without risk, but a good place to start is just to install the latest Siyah S3 Kernel and run it it at 1.6ghz for the CPU and default settings for the GPU. I tried running my CPU at 1.7 and 1.8 and the it wasn't 100% stable and the temps were to high for my liking. Be moderate in your settings and you shouln't encounter any issues.
http://www.gokhanmoral.com/ latest version is 1.7rc1
That will give you a good performance bump with the minimum of risk (in my opinion).
Other than that installing a bloatware free ROM will also give a nice bump. I personally run Omega V29 with the above 1.6 overclock settings and it lightning fast. :good:

There is always a risk involved in overclocking.
1.8ghz isn't stable for most people but 1.7 is quite stable.
How well your device handles overclocking depends on the quality of the chip you got.
This is down to the manufacturing process, you may get a good chip from the middle of the wafer or a not so good one from nearer the edge.
if you want to reduce heat them you should undervolt the CPU, less current means less heat.
Obviously it isn't good for the hardware in the long run but that's what you gotta take into account when you overclock, I've overclocked every phone I've ever had and haven't had any problems but YMMV.

could u plz tell me that what is the process of undervolt if i undervolt the cpu then it is related to only heat or performence also?

If you use siyah kernel then in the stweaks app that comes with it you can choose how much you want to undervolt.
I suggest starting with -25mv or -50mv and check stability.
I use -100mv without problems but like in said earlier YMMV.
It doesn't give a performance boost per se, but less heat in the chip will mean that it doesn't hit the temperature throttle threshold as easily and that means more performance.
The CPU will begin to throttle (limit clock speed) at around 75c until the temp drops and the CPU is allowed to run at max clock speed again.
Usually you will only hit the temp throttle threshold under very heavy loads, for example repeated benchmarks.

1.7ghz should be alright for a 32nm chip like the exynos 4412 on our s3. HTC has had their One S (with a 45 nm chip) clocked at 1.7 ghz. The lower the nanoneter, the more ambitious you can be with clock speeds. Try 1.6 or 1.7 ghz with default voltage settings and see how that goes

You are using -100 undervolt, that mean its high current & mean if i select 25 to 50 then its less current than 100??? & is there any battery improvement if i select less current mean less heat.?

I am using -100mv, as in minus 100mv, 100mv less than stock.
Less current is less heat and *maybe* battery savings.
-100mv is less current than -50mv.

Antutu and Quadrant, all are just bull****. Just to see their manipulated scores, overclocking does not make any sense.
At ground level, applications do not run anything faster as overclocking alone does not work here. Even if you get milli milli milli second improvement which is just nothing against damage of CPU.
Got it?? now start using your phone as it should be and made for.

Before overclocking you should ask yourself Why you want to overclock. If it's because the phone have some lags there is other(safer) way to solve this problem. Honestly I overclock mine for a while (just because I'm a tester) but the S3 is fast enough for everything. You should see my S3. The app drawer appears (almost) instantaneously. Any games play smoothly etc...
On this phone overclocking is possible but useless. If you want to learn how to overclock just to learn how, search in the stickies for the overclocking guide.

I have tried overclocking and undervolting for the last week now and I can say that overclocking has not made any visible difference to my S3. Overclocking seems to be a nice option to have, but the S3 does not need it. Undervolting on the other hand reduces lag considerably when playing games for long periods. Usually my S3 started to get laggy after about 1 hour of Asphalt, but now it does not get laggy at all. I have undervolted by (-)125.
Hope that helps.

When I play pokemon black 2 on nds4droid without overclocking it gives me 20 to 30 fps and when I overclock it to 1.7 GHz i get 28 to 35 fps

Firstly you need a kernel supporting overclocking... Secondly its fine if u wanna play around with your device... Lastly I would suggest u to overclock it to 1704 MHz max (avoiding any boot loops )....
I would recommend Siyah 1.9.1 (as your Kernel) and "Noop" as your I/O Scheduler... In case ure using Siyah as your Kernel, try using "Lulzactiveq" as your governer...
Furthermore u can tweak the governer if u want more juice out of it....
Try it.....

To undervolt you mean to make the cpu frequencies lower? I am doing that with a program called Kernel Tuner. You can set the CPU and GPU speed and set the CPU governor from there.
The phone it has to be rooted.

what i mean is to lower the CPU or GPU voltage.

I don't know how to do that. As I said, I use Kernel Tuner to set the maximum cpu/gpu speed the phone can go. It's not the same thing. But is better than nothing. The phone works really good even with lower frequencies and I don't need top speed except some greedy games. Now I can reach a sot of over 6 hours with 4-5 hours of heavy gaming.
If you can find a way do undervolt please post it.

thanks for confirming, time to return the pro 3 or sell it at a loss. was just hoping that out there somewhere there would be a kernel that has the feature to undervolt.

I still don't see the point of undervolting the CPU/GPU on a phone. As long as it works fine and the battery last long enough (and honestly this phone have plenty of battery, I recharge every 2 or 3 days), why?

Because he used to do that on older device, and thinks this is some kind of a must function lol. I also have no clue why on earth you would need to underclock pro 3, it doesnt overheat, and it has probably best battery life of all snapdragon 821 devices. Undervolting this device would gain you absolutely nothing, nonsense.
