Morning all, I am wondering settings people use with setcpu on their phones. Mine has always been set to ondemand, but wondered what the other ones do and are there any benefits?

Depends on the kernel actually... current trend is leaning towards ondemand, and so am I... I tend to put it to performance for Quadrant tests to eliminate lag, but that seems to be it...
Loving smartass governor since my battery stays generally the same when screen is off. Kernel has to support it though.

Is it worth creating a profile on my Setcpu for charging? I've heard that it can improve charging but I have also heard that it can effect charging negatively?
Thoughts?

I wouldn't bother mate, I just use screen off and in call profiles. Min 128 max 384 on both.

I use one for charging , one for screen off... my batt last for two days on normal use .. love it !!
I have only one profile:
Screen off min 245 max 245 ondemand governor.

How to make two cores working for better performance?

You can use CPU Editor, It's a script that allows you to force dual core and allows a lot of customization. For instance you can run different frequencies on each core along with different govenors and so on, could be great for saving battery life too.
If you have a dual core processor in your Windows 7 computer and one of the processing cores is disabled, you have the ability to make both cores work again. Utilizing both processing cores instead of just one will substantially increase the processing performance of your computer, which will translate into faster operations.

Root your phone. Download system tuner pro from the app store got to Cpu and change the governor to performance instead of on demand... This will use a lot more battery tho.

I actually wouldn't recommend that, in some cases performance is the better govenor for performance but I heard the S3 or the S4 processor is actually optimized for the ondemand govenor. I did some tests and I noticed that they scored pretty close to the same in the benchmarks department, I noticed that the S3 gets hot when using the performance govenor and then it starts to lag here and there but I did not experience this with the ondemand govenor.
OnDemand:
Scales CPU according to the processing needs of the programs running which saves power and is still snappy as ever.
Performance:
Locks the CPU at the top frequency regardless of processing needs which drains battery and can make the S3 insanely hot.

If you read ops request... He wants to know how to make both the cores work at the same time... And I gave him the right answer regardless of what it does to the phone he wanted to know how to do it and I answered.
Now would I recommend having both cores on at all times absolutely not... Phone drains the batter and gets pretty hot.

I never said you didn't give him the right answer I was just trying to give him a bit more info on the performance govenor.

Naturally the second core will come on when it needs to based off the type of governor set. As said before performance governor locks at Max. SmartassV2 does not have smp so the second core never goes offline. Simply turning on the second core really won't give you a noticeable difference in performance.
But using root explorer or terminal emulator, setting
/sys/devices/system/CPU/CPU1/online to 1
Then change same files permission to read only will yield an always active second core.

I only get 3300ish same as wife's. I see a lot of people around 5000ish. I close all apps and clear ram. I am on Rogers. Just curious what score others get on Canadian phones
Sent from my SGH-I747M using xda app-developers app
are you running stock rom/kernel? I just got a tad under 5000 without closing apps or overclocking so what your running will make a big difference.
BTW gotta say hi to a fellow Brantfordian
As stated above, you could overclock your phone.
ON stock tw I normally hover around 5000'ish. 3300 is wayyyy low. Something def going on not right

Stock Rogers 4.0.4, CPU OnDemand 384-1512mhz, /settings/developer options/Force GPU Rendering (unchecked), did not clear ram either.
Quadrant Standard = 4990
Quadrant Pro = 4350
Not that the numbers mean much to me, but these are the numbers you can expect. Perhaps your CPU governor/scaling is set low or deifferent than mine....or also, do you have POWER SAVE enabled?
Yes stock. I rooted and tried various rooms same score. I'm not bothered by the score just checking if others get dame score. I do have power saving on so will try tonight without it. Thanks for all the input guys. I'm trying to get a good base for comparison to jb whenever Rogers gives it to us

Power saving might be throttling the CPU so that its not running its fastest to save power. Definitely try without power saving and let us know.
I'm on CM10 with the ktoonsez kernel not overclocked and I average about 5000, give or take maybe 500. I really can't remember what I got on stock, its been so long
You guys nailed it. I went into power saving screen and turned off the cpu part and got 4955

Great to hear that RegBuckly.
You should FEEL a noticeable difference with certain apps, games or launcher now that you have full speed CPU scaling.
(don't for get to press the thank you button)
I'm getting 3866 in Quadrant (Normal: 5325) and 9586 in AnTuTu (Normal: 16301). Something's wrong, those are almost half what they should be.
I'm running ParanoidKANGDroid and set the CPU to "Performance" in case it was doing some powersaving stuff... is there another powersaving setting I'm missing? I turned off GPS and Sync. I even put it in the damned freezer. I've run both benchmarks multiple times after reboots and all of that and it's pretty consistent with those scores.

My S3 was getting really hot after rooting so I decided to try undervolting. I was able to under volt each clock speed by -100mv, and my device hasn't seen any performance issues, runs cool, and battery lasts way longer! What do you guys keep you voltage settings at?

It doesn't matter what other people UV since all devices are different. I can reach -125 all steps (haven't tried farther) but some others can barely do -25. It's just how their device is built.

I understand. I'm just wondering what people are running at

The reason I personally don't do both under clocking and over clocking is that the phone itself isn't made for that. I personally don't know what this phone can handle. I have seen people under clock and over clock phones and have it work while some people have phones that can't handle much at all especially the refurbished ones. My S3 handles it well but I only tried it out once. That's my feeling on the subject. If you do do either undervolting, under clocking or over clocking just remember to do it responsibly and not put it to highest power and leave it there.

I have lyapota kernel with undervolt but get this cpu temp. Is this normal?
Sent from my HTC One X using XDA Premium 4 mobile app
That looks extremely hot my friend, I have never seen mine that hot.
What was your phone doing to reach those temperatures?
What are your settings?
Which version of kernel?
Governor?
Voltages?
here's my temps
Using lm#17 pre aroma
-75 cpu undervolt
Even under full load I'm only seeing a maximum of around 50-55

Highest at 81°C is normal...it won't go pass that. Stock kernel capped at 85°C. When reach at that temp, CPU will be throttled to maintain below capped temp.
Just don't play heavy games while charging. Almost can fried egg with this phone. [emoji39]
