I have noticed that most kernels are overclockable to 1863mhz and higher. Are some phones actually stable at these clock speeds? I ask because mine will only stay stable at 1736mhz. This is with any ROM/kernel combination. Are all phones a little different in the aspect of what they can handle?
What are you guys stable at?

Yeah each cot core is a little different as to how much it can be overclocked. I was only stable at 1.7 something.
I always have it at max. 1836 (highest possible with my kernel) with scaling ondemand. No unstability so far....

Definitely changes from phone to phone, I've had 4 ThreeVOs and each one had its own tolerance. My latest can only get up to 1.7 before becoming unstable, the first one I got could only go up to 1.5(!) and the last one I had got to 2.0 before it crashed altogether (wish I still had it D: ).
Unfortunately because of a less than perfect manufacturing process and a few different revision numbers each phone is different. So far I haven't been able to go past stock and never get a crash. Even one crash a week is unacceptable to me.
It also will depend on a few other factors though, like kernel, firmware, OS, voltage and temperature, so I personally haven't had the time to play around with the variables you can manipulate to increase stability. It can be done though, without getting a new phone.
So there is something that I'm trying to figure out.
I am currently running Virus' Infected Eternity 1.5 r31 and using RCMIX 3D v11 kernel. Regardless whether it is overclocked (which I usually run 1.51 ghz) or standard and regardless of whether running a govenor like lagfree or a SetCPU one like performance, when I open the app SystemPanel Monitor it shows only one core running. According to Freeza's thread, his kernel has "dual cores active" and it shows SystemPanel Monitor with two cores running. I switched to Freeza's kernel with Eternity ROM and and checked again and it only shows one core running.
So what I'm trying to figure out is, is this ROM related or am I really only running one core and the other is not used, or otherwise how do I know if both cores are running?
My phone with Eternity ROM is smooth and runs games and videos well with no choppiness so I think it is ok. I just want to know how we can know that both cores are running.
I would also like an answer to this question..
Its because of SetCPU if you remove it and install say CPU Master your second core will be activated.
I thought the latest SetCPU was setup for dual cores?

Download stability test...run the first, classic test...hit the home button..not the back button...open your system app and it will show you that both cores work, when needed, on the rom you think is only using one core.

This Worked!! Thanks cruecu. Seems as though if the demand is not there the second core is idle for these particular govenors.
So this begs the questions.....Which is better (for speed and/or battery life), running mostly one core at full speed and then the second when only necessary, or running both simultaneously at half speed? I've seen some discussion on this but it's not real clear.

I'm not sure one has been proven more effective. I personally don't want both cores running all the time...I don't notice a speed increase since clock speed is still the same. Not sure it matters either way, but I will only run a rom that uses second core only when needed

For the most part I agree with this statement. The reality is the device feels faster and will benchmark better. The better benchmarking is what sold a lot of people. The question still remains is if the device finishes processing the data in half the time is it using more battery? I personally have not noticed a drain on the battery and it may even be a little better. If you let the device decide when to use the second core it may never use it.
Also on some ROMs like my Fresh ROM you can just delete the dual core script in the init.d folder and it will return to single core mode.
Ok, I have side questions that pertains to this topic.
If we can enable the second core in init.d when the phone boots, AND it actually does useful work then HTC would have had to have put effort into supporting that in their kernel because ASOP Gingerbread does not naively support dual core, right? So that makes me wonder why HTC shipped the 3D with dual core inactive! Unless I'm flat out wrong somewhere HTC must have had a reason, and the only things I can think of are race conditions and battery life.

Our CPU was not designed to run this way (asynchronous CPU). That is why it is not active all the time. Now Nvidia Tegra processors (synchronous CPU) are designed to run dual core all the time. That also seem to produce better benchmarks.
HTC kernel is designed to run the way the processor was designed. HTC would not override the CPU specs like we would just to make the benchmark better. The theory is that asynchronous CPU would have better battery life. Reality is most XDA members only care about benchmarks so they can show their friends.

While I agree with you in principle, I do have both cores active at all times. I have not noticed any difference in battery life. Yet I have noticed a difference of quite a bit less lag while loading applications and flipping through screens than when CPU1 is idle.
Does it really matter in the long run daily use? Not really. It's a fun tweak and I learned something new by utilizing it.
I did not get a truly noticeable difference in benchmark though.

First I am aware that overclocking is not "safe" and all that kind of stuff
However for some reason I am unable to OC my SGS2 and run the phone on a steady way.
I have tried several ROMs (stock and custom) with different kernels and OCing apps with no avail.
I am not even able to run at 1.4Ghz or 1.6Ghz without having my phone reboot or hard lock on me.
Is there a particular or recommended setting (most successful combination) that anyone out there can suggest me trying?
Sometimes it will hang under heavy gaming but sometimes even browsing app and regular stuff will cause the phone to reboot or lock. If I work with no OCing at all then everything is fine and dandy.
Thanks, you can see my current configuration @ my signature.
Sounds like a very temperamental cpu. Currently I have the same setup you do and have never had issue with 1400mhz or 1600mhz. Though I usually leave mine at 1200mhz. What app are you running when it hangs?
And just as important, do you have alot running in the background? The modified touchwiz launcher unnamed comes with can be enabled to show a red dot next to the apps that have been opened and are in the background.
If you could list the apps with the red dots.

Not all CPUs can overclock - there's a reason it was sold as a 1.2 GHz chip.
Well as I've mentioned before, it could even hand when browsing through my apps menu, browsing the gallery, playing a game (non in particular) and the funny part is that the phone is not even hot to touch.
What I know for sure if that if no OC = no hangs, no reboots.
I do have the App monitor widget that comes with the stock ROM and currently using it on UnNamed 1.3.1 and I only have Widget Locker App. However I have try closing it and still will happen.
Not sure if maybe this CPU is somehow having an issue that makes it unstable as soon as I OC it.

Now that is new to me, I thought that all of them were OCable. Is there anyway to identify which can be or not OCed?
nope.. just by testing. it does have to do a little bit with the kernel and rom. the roms didnt originally have stable OC. i would assume that all of them do now. one thing you might try is giving them a little more voltage (just a little) at the higher clocks, but be careful. if you increase the voltage that means that you will sink more enery through the cpu and it will get hot quick. make sure you watch the temp.
i find that setcpu is less stable than the built in cm7 oc menu but cm7 doesnt have a voltage menu.
but on the same token... why OC? i can and i did but i dont need to... everything is like butter and i didnt see that huge a gain by OCing it anyways

have you ever overclocked PC CPUs? if you have spent much time doing that, then you would know that not every chip, even within the same model/family, will clock the same. take 2 CPUs, from the same batch, same model, with identical hardware tied to them. you will probably find that one clocks higher stable speeds than the other.
its very likely the proc in your phone just cannot handle the overclocks that the next person's could.
Like pirate said, no two pieces of hardware are identical. Sort of shows how much variance there can be in a manufacturing process. Id guess theres a few chips that come off the same line that arent stable at 1.2 ghz, but they dont make it to the devices, whereas one that can handle a higher clock will. (No sense tossing one that exceeds minimum requirements, thatd just be throwing good hardware away)
You could try nudgin the voltage up and seeing how it behaves, just use caution.

To get mine to overclock to 1.4 and 1.6Ghz I had to actually INCREASE the voltage settings via Voltage control app. So my settings are: 1.6Ghz= 1475mV and 1.4Ghz=1325mV
Try those out and see if is better for you. I tried undervolting the higher voltages and would either lockup or reboot instantly until I tried adding voltages. So you may need to play with your settings to get it to work for you.

Yup, or if they want to sell a "premium" device with a higher clock rate, they will take the parts that test well at 1.4 and sell them as such - meaning parts rated 1.2 will be LESS likely to be overclockable if a device comes out with CPUs rated at 1.4 - like the Galaxy Note did.
Before, anything that could meet the requirements of stable at 1.2 was sold to any Galaxy S II - but now, the premium parts are going into the Note.

I am having the same issue as the original poster on my new GS2. I will have to try the settings you mention but would it be possible to do this and also apply /UV to the remaining lower (1000ghz to 200ghz) processor speeds and maintain stability?
So I installed SetCPU today. Been testing the kernels ability to work underclocked at the max of 918mhz. Also set the scaling to conservative. After a days use it's been as good as normal full speed, 1512mhz
The battery lasted throughout the day, compared to my first two days of stock settings with only 6 hours of good use.
I'll keep playing. Still want to do some testing and benchmarks to make sure it's not under performing. But at least at the user level it seems to react the same.no lag.
I did confirm the clock speed out side of SetCPU using system panel.

Don't bother using benchmarks to rate a phones performance that is a fatal error there. Benchmarks never effectively rate a phones performance. I just go by how smooth the phone runs and it does it run everything I throw at it. If so gg pz end of story.

Well whatever works for you. Just saying Quadrant is a poor tool to use to bench for many reasons which I won't go over. Antutu is nice for SD speed testing I think, oter than that meh. Benches are just for numbers for people to flex their epeens with. They just really don't truly gauge a devices performance.

Benchmarks do have a some good uses... while comparing different phone models with benchmarks can be iffy, it can give an overall insight, (things like graphics capabilities with very GPU extensive games) but in the end user experience and daily use are the real judges.
Where benchmarks can be of the most use, is when comparing changes to the same phone model.
E.G. Comparing performance impacts of AOSP vs Sense, overclocking and under-clocking, and de-sensing/bloat removal.
When used for these reasons, you can get a really good feel for how changes are affecting your device overall. Even then, benchmarks are not the be all end all, and user experience is still important. As you may introduce lag or other performance issues that do not show up in benchmarks.
Which temp root method are you using? Mine isn't staying rooted long enough for me to justify using setCPU at all...
The new version and the one that comes with the newest clean tool stays until reboot.

Please let us know what settings you use that work for you.
I generally stay temprooted unless I'm going to be away from a charger for a bit and need BT (since you can't turn BT back on after temproot). I wouldn't have SetCPU autostart on boot (since it won't ever be able to get root access immediately after boot).
Meanwhile, I also set it to conservative and will see what that accomplishes.
A kernel needs to support setcpu, stock kernels do not. You need to flash a custom kernel, so you need a development phone or s-off.
Sent from my ADR6400L using XDA App
This kernel apparently does work with SetCPU. I've confirmed using other cpu monitoring apps that the clock speed changes are capped.
I own 7 android phones, and have been rooting, overclocking, undervolting each and every single one of them (well one I still cant get rooted). I know when the cpu is under clocked and when it is not. Been doing these tweaks for 4 years now. If you use a tool like System Panel, at stock settings you can see the max cpu around 1500 on our little bad boy. When it peaks out the clock speed is shown. When you under clock it, then check again it won't go beyond the max cpu set in my testing I put a ceiling at 918mhz. System Panel reported full CPU usage (100%) at clock speed 918mhz. Typically with stock kernels, your absolutely right, changes to SetCPU do nothing at all to the real cpu. Which is confirmed, when I reboot and dont have root, if I attempt to use SetCPU and make the changes, System Panel reports 1500mhz (roughly) at full load regardless of what I set it to in SetCPU. If I did this to any of my other phones with stock kernels, you are correct it makes no difference as SystemPanel reports the stock max setting.
No I'm not being mean or aggressive, just saying. =-) And no don't believe me, but test it yourself and confirm or prove me wrong some other way and I admit error. Either way, half the fun is messing with the phone and trying to get it to do things it should not do.

In my view, the "benchmarks" would be an OK measurement if you were comparing apples to apples.
I tried running both Linpack and Quadrant on the very recently and dearly departed Incredible right after a fresh reboot and having charged the battery overnight...when the thing should have been at it's freshest.
I got wildly different scores each time I ran it after a reboot...knowing that on both programs the scores would improve the more times you ran the test.
It didn't seem to me that either program was a reliable indicator of what my phone was capable of. I didn't even trust them to tell me whether something I'd done...cleared cache or deleted bloatware...had any real effect.
It simply boils down to how the phone feels. That's not scientific, but it works for me.

Linpack and Quadrant are not reliable benchmarks. TBH I don't take any of the benchmarks seriously, they are more for entertainment for me. But to each their own right?
Yeah some of the benchmark apps are a bit unreliable to say the least...
If I use one, I try to use ones that Anandtech uses. I trust them to find the better benchmark tools.
I have been messing with Antutu CPU and SetCPU just to see how well each is working. (never installed at the same time)
Been using System Tuner Pro and System Panel to watch the CPU.
With no CPU app installed, STP shows that the 2nd core is "offline" and SP shows no activity at all on the 2nd core either.
With Antutu CPU installed the 2nd core shows offline/no activity as well.
When SetCPU is installed, the 2nd core shows activity.
Sometimes it scales even with the 1st core and sometimes not. It scales both higher and lower than the 1st core, I am guessing the OS is issuing separate threads to each core and each thread's demands dictates the load of the individual cores.
I know that the 2 cores can scale Independent of each other, the 2nd core does not need to scale with the 1st core like some other current CPUs.
So what is going on to cause this? Is the kernel set to only use one core by default? I never seen any load for the 2nd core, even when running a graphically intensive game, and checking the load history.
And why does the 2nd core start working when SetCPU is installed? What does it change that Antutu does not? Seems we can get much better performance if SetCPU really does enable the 2nd core over what is default in the kernel.
So anyone have any thoughts on this?
Edit:
Antutu bench shows no improvement.
Glbench... Need to test more.
Linpack... Stock it shows an avg score of 48 and when using multithread option avg score of 43.
When SetCPU is installed, the scores are 48 and 75 respectfully.
I'm not 100% sure but I think I read somewhere that this is normal.The 2nd core remains inactive until it is actually needed.
the problem is that gingerbread is not designed to utilize a multi-core cpu. if you want to see both cores operational you'll have to move up to ics... that and i think they are still working out the bugs in that.

I am running scott's ICS cleanROM...
There is definatly no second core activity, but there is after installing and using SetCPU.
Funny, I was just going to ask about the second core. I have been keeping an eye on it in System Panel. Never shows any activity.. Seems inactive... Even when I checked history while running N64oid... I was surprised to see that emulator wasn't utilizing the second core. Although the emulator does run very well, it could definitely benefit from additional core..ks this all because of Gingerbread? It would seem like an app should be able to make use out of it... After all, it was shipped this way.

that being the case it can be dependent on the build/settings. the setcpu thing makes sense due to the nature of the app. even then, depending on rom/kernal, setcpu allows not only for under/overclocking but also voltage control.

Antutu cpu doesn't cause any activity in the second core, only setcpu. Seems both would work the same.
I don't play with these apps very often, but because some of the kernels jump around, I tried CPU tweaker. It shows both cores, and temp, and load. You might check it out just for fun. It seems to show both kernels, and their frequencies. I wish I could be of more help, but this is my first dual core.

If u want them both on, remove the mdprecision file, or copy it and move it out of the folder, or just rename it, and then reboot and the second core will be on. I usually copy mine to the system folder and rename the original by adding .bak onto the end
I think its located in /system/bin
It does making a difference having them both on, battery life will be a little less but not much. But it goes faster during app switching and such.. it gives it an edge I think. I leave my second core standard on demand, because its fast enough for me like that and battery life is a little better.
Edit: also, generally my phone benches a little higher with both cores active, instead of the stock way and the second one being on demand. Anyway. Try it, xD
Edit 2: Oh also, if you want to revert back, place the mdpresicion file back in the /system/bin folder and reboot. I assumed that was self explanatory, but just in case lulz
I guess its never safe to assume though
I would think leaving it offline unless it's actually needed is a smarter bet unless you're a benchmark whore.

It does making a difference having them both on, battery life will be a little less but not much. But it goes faster during app switching and such.. it gives it an edge I think. I leave my second core standard on demand, because its fast enough for me like that and battery life is a little better.
Edit: also, generally my phone benches a little higher with both cores active, instead of the stock way and the second one being on demand. Anyway. Try it, xD

Mm I've actually scored higher w/ benches w/ leaving the file intact. 6,500 on Antutu on ics and 5,800 - 5,900 w/ the file renamed/removed. But tbh I could care less about benches since they mean jack to me, I'll play around with this and see the batterylife/performance.

how do you change the settings of both cores separately as in leave one core ON DEMAND and the second on INTERACTIVE..is there an app that can do that or is that something done on a different level.

Lol maybe u can do that eventually with ICS but I'm not aware of a way to do that now though. That would be pretty sweet though.

Yea, I'm not saying it was always higher but they were usually. I definitely had some that were lower too though. I never tested that with ICS either. Only GB. But I did notice that UI interactions were a little snappier for the most part
That's why Benchmarks are silly

Edit 2: Oh also, if you want to revert back, place the mdpresicion file back in the /system/bin folder and reboot. I assumed that was self explanatory, but just in case lulz
I guess its never safe to assume though

Are you talking about mdprecision or mpdecision?

I'd,edit my posts but that's just too funny
I just found it odd that even in ICS the second core was offline when ICS is supposed to be optimized for dual core.
It wasn't that it came on sometimes under very heavy load... it just never comes on.
And like I said, SetCPU is the only way I have found that enables the second core.
Hopefully people with more knowledge about this than I can figure out what is actually going on.

lol i just wanted to make sure
Maybe only the Gnex is designed in a way to use ICS' dual core optimizations until actual OEM releases of ICS come out where it somehow enables it.

How do you mean enable it via setcpu?
