Hey guys,
i know that there was an overclocked kernel for GB, just curious if any developers are planning on coming out with an updated kernel for the View Honeycomb that will support overclocking....now with HC we can really push these things to the limit and get the most out of them.

LeeDroid's ROM has a kernel which allows overclocking.

The CPU usable limit is about 1.8 vs. stock 1.5 Ghz. So you can get a little more, but you have to remember for most of the intensive tasks, its not the CPU.... but the GPU that does the brunt of the work, therefore you might not even notice the difference when the CPU is overclocked. For example your Gt3 game won't frame any faster because the video is rendered by the GPU, not the CPU. The custom kernels also enable some difference CPU governor schemes, which might improve observed performance for some things. All of these things factor into battery usage. In general increased performance means more aggressive use of battery power.

Hey, what about our bragging rights?
We already have the fastest CPU on the market. Do you want to crush and disenfranchise the competition?
I actually would prefer under clocking, undervolting better process management. I want better battery life.
Leedroids, custom kernel , and others, allow for under or over and also for precise voltage adjustments at each speed. Other ways to get better battery are various governors that are less aggressive than the performance governor. Check the Leedroid and other treads for more info. Of course the biggest power eaters are the display and the GPU, if you are doing video or games the GPU will consume a lot and there is not much to can do with that. Display on eats battery, you can reduce brightness to help.

call me a noob but i gotta ask, just what does the kernals do to the phone thats so special, and all the ghz talk means what. i rooted my device for the teather and customizing, and now i see all this talk of kernal this, overclock that, and different ghz people are getting can someone explain to me what this does for your phone, should i be interested???
popcorn kernals?
the higher your ghz the faster your phone is.
overclocking is making your ghz higher
and kernals is what allows you to overclock(sorta)
lol dude...you should prob. take your time with customization but ghz is in reference to the speed of the processor. So...theoretically the higher the number the better your phone should perform...t, eoretically lol. Note that with a higher ghz value the worse your battery life will be unless the kernel is written really well. Also the kernel is the code that controls the devices hardware. (brain)
The nice thing is that you can generally play with different kernels without having to wipe and redo your phone. Also, if you really want to play with the various kernels out there you should get setcpu from the market. It let's you set your phone to make use of the processor in an over clocked (OC) application but it can also let you under clock your phone when your not using it, such as when the screen is off. This will help you conserve battery life. But be careful, over clocking can lead to over heating and other problems if you''re not careful
sounds very interesting, hmmm. so in the coming months people could create kernals to acheive speeds to challenge dual core phones
the kernels already are challenging dual core phones. The thunderbolt currently has a 2ghz kernel. The motorola atrix is a 1 ghz dual core... Thunderbolt definately rivals it with overclock kernel

A "kernel" is the OS layer that sits between the applications and hardware. So, when an application says "light up LED" it eventually goes through the kernel to do this, most likely by a request/system call.
The speed of a CPU is measured in hertz (frequency). So, a 1 Ghz CPU can perform over 1 billion operations in one second. The frequency can be increased (overclocked). When you do so, this can damage the CPU (most likely due to heat). Heat can also cause the CPU to run efficiently. So, if you overclock too high, you COULD end up running slower than if you had just left it at 1 Ghz. Changing the frequency can also hinder stability.
so with it being so dangerous how do u know what kernal to trust and whats a safe limit in hertz, do u stop at 1.5, because 2ghz sounds like pushing it
This thread is so full of misinformation it is comical. To start, higher clock speed does not always result in better performance.
Secondly, everyone has their own preference. The best bet is to find the perfect balance for your needs. For many people, overclocking the CPU is not very beneficial... since the device is already plenty fast at stock 1GHz speeds. A lot of users would rather use custom kernels to make their device more power efficient and use SMARTASS governors and lower voltages.
Mess around with kernels and see what you like the best! (always remember to create a backup before flashing... this allows you to easily revert back if something goes awry).
You mean they're not popcorn kernels?? Lol

It should be noted that most phones are definitely capable of being overclocked to a reasonable extent.
the majority of kernels we nexus one users play with, is undervolting the and playing with teh voltage tables to maximize standby battery life, at the same time overclocking the high end to improve performance. but really its about lowering voltage to improve battery life.
Hi im thinking of doing a overclock to 1.5 ghz is it safe for the processor and the battery life witch already sucks. has anyone on here whos done it using setcpu and the rom had any problems after doing so ? and how much faster is 1.5 ghz compared to 1.2 ghz on the galaxy s2 ? and is it safe in general for the hardware of the phone will the phone get hotter or have over heating problems ? also what should my settings be for minimum maximum and the voltages ?
Of course oc is going to make ur battery life a lot worse.

I haven' used Setcpu in a while but I believe it's got a feature to stress test the settings to see if it can handle it. Generally the worst that happens is it'll crash. So long as it doesn't get hot. Heat=death for electronics :')
I'm using tegrak (from market) to overclock to 1.4. I found 1.5 was too unstable. Noticeable difference between 1.2 & 1.4 is almost none. Also voltage increase of 50mv was needed to gain stability. There is not much point of overclocking the device IMO unless like me u just get some satisfaction out of knowing its running faster!

This is true. I see no difference between 1.2 & 1.5ghz. But that doesn't keep me from running it at 1.5 when I'm playing a game anyway :'D

Well it's not safe, that I can say. Nothing is safe when you don't know what other things are changing with the clock rate. But still you could do that. You just have to make sure that the temperature is within limit, it will be definitely high, but make sure it's not that high.
And upping the clock rate to 1.5 GHz won't drain any extra battery than 1.2 GHz.
Regards.

I tried the overclocking and each phone is different, increase then test, there are many benchmarking apps out there, I was stable at 1.4, my kernel does not include 1.5 GHz, and irregardless of what people may say, running the phone at higher clock speeds consistently DOES drain the battery more than 1.2GHz, unless you have found a way to manipulate the laws of physics. I don't see how one can fathom the thought that you can get a faster CPU at absolutely no cost.
Many people think when the CPU running faster means you complete tasks faster, hence 1.5 would complete a task faster than 1.2 and hence save battery, but I believe we use this phone as more than a calculator, so when you are performing a task that causes the CPU to run at 1.5 for a period of time e.g playing a game, browsing or whatever you do with your phone, then the CPU has to draw more power to keep the frequency at 1.5 as compared to the CPU running at 1.2
All in all, I dialed back because I was doing fine without it and I did not need it, other people may need it, and I wasn't gaining anything. to answer your question directly, it all depends on what you do with your phone, I'm not a huge gamer or anything and the 1.2GHz has proven to be more than enough for me to have a very pleasant experience using this device
Using it occasionally is safe, unless you stress your mobile at 1.5+ ghz for more than an hour or so.
The cpu governor will only make use of higher frequencies when there is a need, so mostly you will see your mobile idling at 200 mhz.

Not necessarily a lot worse. It depends on how you are using your phone, and what is causing it to run fast. If overclocking allows the phone to spend longer in deep sleep state, your battery will win. If its games, and by OC you achieve a higher frame rate, then the phone is doing more work, and this will be reflected in the battery life going down.
Most of the time, screen on is going to dominate. If you are a low screen-on user, I guess there is more chance for a higher max_cpu to be beneficial (it won't be used unless there is a task that requires it). More accurately, it helps some of the time, so the net result is not always obvious to predict.
How about undervolting?
Any danger in doing so- other than crashing when voltage is too low?
Before over clocking it might be worth downloading cpuspy from the market and seeing what time you spend in each speed.
Chances are most of the time you won't even hit 1.2 so might not have anything to gain by over clocking.
Then again I dont know how you use your device but I do know I was surprised when I found out.

I've played with the SuperSonic version of this phone (which has a 1.5Ghz core) and the results from photos/video are much better, I'm pretty sure the cameras are exactly the same but the SuperSonic benefits from the higher CPU.
I think it would be cool if somebody could write an app that states
IF user opens Camera application voltage + clock speed is increased to allow stable 1.5GHz speed
WHEN user closes camera application overclock turns off.
Thoughts?
You have a smartphone! Not a pc!
I didnt see any advantage if you oc to 1.5
Btw In normal use your phone keep in 200mhz not 1.2.
I think i only hit 1.2 two or 3 times for 3 seconds in a full battery cycle.
Sent from my GT-I9100 using xda premium
oc dosnt make sense ,there no noticeable diff,an yes very few times i hit 1.2 mostly its on 800 or few times on 1000....using a device with 1.5ghz proccesor an oc a device to 1.5 ghz which has 1ghz processor is very diff in nature....
Fair enough.
Well I wouldn't mind an app that mazes out at 1.2GHz with camera app open, as it can lag when shooting HD.
oc upto 1.4 ghz is fair enough, anything more than that is a waste. though you cant find any visible difference between 1,1.2 and 1.4 it does helps in maintaining smoothness on some situations.
yes very true i had oc my sgs1 at 1.2ghz and sgs2 at 1.4ghz but frankly i dint see the diff so after few days use i turnd to orignal settings....but many use oc an phone works fine,but depends on personel use......an yes as bala_gammer says its fine on 1.4ghz......cheeeerz

I also noted that gameloft games are makes more over heat for phone..
Which is the best and safe voltage level for 1.4 ghz 1250mv or 1275mv or 1300mv

Hello, I have an HTC thunderbolt, rooted with CM7, and installed setcpu and used autodetect and I put the CPU govern to "conservative" with minimum GHz 245 and maximum 1.8GHz and I am just wondering if this is safe? because I read some threads about Compatible kernels and I jave no idea what that means, they were also talkimg about undervolting, which agaim I do not know means, anyways thanks for reading

If your device will run reliably at 1.8GHz, then there's not much to worry about as long as the voltage isn't too high. High voltages and heat can shorten the SoC's life or kill it altogether. Generally, I don't recommend running that fast because the performance increase isn't as great from 1.6GHz to 1.8GHz as it is from 1.41GHz to 1.6GHz. These cores weren't meant to run any faster than 1.5GHz really, and anything past that doesn't increase the performance as much as the numbers might suggest.
Also, a conservative governor probably isn't ideal if you're willing to run a device that fast. That governor would seldom, if ever, use that kind of speed. I'd suggest smartass, smartassV2, ondemand, or interactive if you're looking to see a good boost in performance.
If you're looking for an app to view and adjust voltages, IncrediControl works well. For all the nitty-gritty of overclocking, I'd recommend reading my OC guide. It's in the "Second Post" of my Q&A thread. If you've got any questions, feel free to hit me up.
So does over clocking just speed things up? What are the real benefits

I look at it like this. My screen eats up most of my battery. The less time it's on, the better. Overclocking uses more power for the CPU, but the display spends less time telling you it's waiting. It doesn't really add functionality, just speed and efficiency.
How can I have both cores run at the same speed all the time? I think this is the reason my phone's performance suffers when I overclock it or just even using the stock frequency.
Currently, I have it OC'd to 1.83ghz but I can see a drop in performance. Ive tried to increase voltages, but it makes it worse in some cases. However, Ive noticed that when both cores are on and operating at the same speed the phone becomes fast.

First off, what kernel and ROM are you using?
Second, generally speaking at speeds above 1.56 to 1.62, the L2 Cache doesn't sync with the processor speed and they kind of fight against each other. On a good kernel overclocked to just 1.62ghz you can beat a poor kernel at 1.8+ all day. I would suggest only overclocking to 1.62 max.
Third, if you install Kernel Tuner it has an option to link the two cores together so they run at the same frequency.

I am using Coolexe's rom with his latest kernel. Can't I force them to synchronize? Ive tried that and system tuner. They do not work all the time. I think it has to do more with scripts.

Hi there,
I (probablu) ran into the same problem as you did: whilst playing demanding games (like GTA 3/Vicy City) the device stutters and is having difficulty producing a smooth framerate. On an HTC Sense rom whilst playing GTA:VC I had like 13 FPS @ low settings (18% draw distance, 70% screen resolution, medium GFX settings and dynamic shadows OFF) and it was just awful. Then I decided to put CM10 on my device. In the settings menu there is an option called 'Performance' and you can change the profile there. The default profile is 'ondemand' but I changed it to 'performance' to let the quad-cores work at full capacity. Now, all of a sudden, I can run GTA:VC on the highest settings possible at a steady 30+ FPS.
If tl;dr: don't bother with 'game boosters', they will just terminate proccesses running in the background. Instead flash your device with a nice ROM: CM10. It has A) better battery life because there are no unnecessary processes running in the background and B) overall better performance due to the fact there is no SENSE interfering.
Just my two cents.

Actually this app is no joke and was made specifically for the one x, with this app you will achieve greater performance than with cm10 or forcing the performance governor which will just overheat your phone, the tegra 3 processor couples the gpu to the cpu, for example when the game uses only two cpus the gpu is limited to half speed which is why gameloft games lag, gaming boost decouples the gpu, optimizes the cpu governor and sets the minfrees to aggressive so that the game receives enough ram to maintain a stable framerate.
