I need an expert advice o n thee isuue of OverClocking, please state some advantages and disadvantages of OC kernel??
When one is sensible enough not to oc cpu to much,
Advantages are:
-more fluid device performance
Disadvantages:
-the higher the cpu clock speed- the more heat it produces,
and the heat is a silent killer
By overclocking, one can shorten central procesing units' s live
-oc above sensible limits, causes freezes, random reboots,
unstable device performance
To prevent the above mentioned disadvantages from happening,
it is advised to undervolt the cpu- while overclocked...
Oc to 1.2 is enough

So I rooted my Droid X2 and installed Set CPU. I had problems running set CPU, I couldn't use the drop down menu for setting CPU governors, I also couldn't over clock my CPU, just under clock. Does set CPU work with the nvidia tegra 2 dual core processor in the X2? If not, which app will let me overclock and change CPU governors?
You have to have a custom kernel that allows overclocking.

I'm really new to Android, i've been using iOS for years, and finally jumped the fence. I just rooted my Droid X2, used Titanium Backup Pro to freeze all the bloated apps, and I wanted to get more control of my CPU, as well as overclock a little. I thought I could just install SetCPU and I would be able to Overclock.
So in order to have a custom kernel I would have to install a custom ROM? Such as Cyanogenmod? As I said, I am pretty new to Android, but if I am correct, Cyanogenmod is not available yet for the Droid X2 is it? Are there any other custom ROMs that are available or would work with my X2?
Is it really even all that necessary to overclock what is already a pretty powerful device? Nvidia Tegra 2 dual-core processor is powerful in its stock form isn't it? I would almost think I would gain more by dialing the CPU down at certain times, at least I would gain battery life. I think I am able to set up profiles with SetCPU without having a custom kernel, right?
This is a useless app made by Vietnamese people (I'm Vietnamese). It cannot overclock which many people mistakenly believe, and it only has the task of limiting the CPU speed, the CPU speed is managed by the OS and limiting it is a bad way because no matter what task it does it will be slowed down. When idle the CPU will automatically reduce its voltage and speed by OS. Any process no matter how big or small with high CPU speed it will be processed very fast even with small tasks that are reported not to use up CPU but it will still be faster than a slower CPU. Kernel Auditor is also useless.
it's not you install a custom kernel to manage cpu to overclock by some app but you're going to overclock into kernel using a custom kernel
OK guys. After much searching i've just become confused as to which is the best overclock app/ROM for the HTC sensation z710e. I used SetCPU but it couldn't actually take my processors above 1.188GHZ and I tried the sense-o-maniac ROM and also the android revolution 6.0.3 ROM, both of which say the processors are overclocked to 1.5GHZ but there is absolutely no difference to me, no they are not slower, and I just want a clear straight up ROM or app that OVERclocks.
Thanks,
Sensation lover
I under clocked my cpu to 1 ghz and I see no difference in speed.... From 1.2 to 1.5 its 20% increase in cpu speed.... Speed of the phone doesn't depend on cpu alone... So thats around 7-10% increase in speed overall (because there is gpu, ROM, sd card, memory)... And thats maybe... Do you really think you can see 7% in speed? Try some synthetic cpu benchmark with 1.2 and 1.5 and only then will you see....
This is my five cents ;-)

Well the app that controls the CPU clocking is limited in what it can do by the Kernel you're running.
If you're Kernel only supports 1.18 Ghz, Set CPU can't do anything about it.
So you need a Kernel that supports overclocking. The Kernel also controls what kind of governors who can put on the CPU (Conservative, performance, battery saving, etc...)
As far as the controller apps go though, I like the ones that can set the screen off speeds at a different rate than the screen on speeds. That makes sure I don't drain battery at alarming rates when the phone is in my pocket because a rogue app decided it wanted to get funky.
As Skipjacks mentioned, the overclocking speed is due to the kernel you have flashed.
If you are unsure on which kernel to use,
Always use the kernels suggested by the ROM developer.
Of course, you could try various Kernels but do keep in mind that not all ROM's support different kernels.
Normally the current roms has CPU clocking apps built into it,
one widely used is the Daemon control. It usually comes with an app that you can control the overclocking speed.
The current app i'm using, I use System Tuner Pro (yes I support app developers)
It enables me to force cpu2 online, which ultimately makes my phone faster.
hi all,
i want to root and overclock my TF300T
for the overclocking:
-Can i use setcpu ? What other tool is good for OC ?
- Do i need a Costum ROM for overclocking to 1.5Ghz (MAX!)
-Will the performance be a lot better ? or just better ? or no diffrence ?
-What is the highest possible OC ?
Thank you
If you are on ICS you can over clock to 1.5 no problem. I don't know about Setcpu on ICS, but I do know EzOverclock works.
If you upgraded to Jellybean, I don't know of anyway to overclock as of yet. EzOverclock won't work on Jellybean and reportedly causes boot loops. I tried setcpu on my Jellybean Tf300 and found the CPU to be maxed at 1.3.

It really depends on how you use the tablet, and where your bottleneck is. My feel is that I/O is the biggest bottleneck on the ASUS pads and the effects are felt across the board. I believe ASUS is working on a fix, though. Fingers crossed.
I/O notwithstanding, day-to-day tasks like email and web browsing don't need a 1 Ghz. Even video playback won't be affected by the difference between 1.2 Ghz (the ASUS performance mode) and 1.5 Ghz (typical max OC). Rendering graphics, I'm not sure how much is offloaded to the GPU, so games or graphic heavy applications may be where you'll see the most gains.
EZoverclock don't work on JB it will keeps restarting your tablet when EZoverclock starts.
And other apps work but can only be set to 1.3 so no overclock on JB with this kernel.
I think in graphically intense applications, such as games, would offer the most notable difference even with gpu offloading since not all instructions are graphics related. That being said just know that battery life will take a hit.
Remember...... as of now EzOverclock will not work in Jellybean.....

[APP] - EZOverClock to 1.6 ghz

Dear XDA people,
Im currently working with Max's V4 RC2 kernel in combination with Cromi-X 4.6.9 (still need to update to the latest), which gives me a pretty smooth working tablet.
Now, im running the cpu at 1900mhz, 1225mV (still testing if i can go lower), and I can adjust speed and voltage nicely with Trickster Mod.
But, I would wan't to crank up the gpu speed (which is currently 666mhz I think?) and have the same "options/settings" available to do so. For example, a rom limitation of 750/800mhz on the gpu, with a variation of voltages to choose from. This way I can get as much gpu power as possible, since i find gaming on the tf700 pretty disappointing in terms of performance (of course a lot of games are not optimized for tegra).
Do you guys know what would be the best possible solution to overclock/adjust the gpu speed+voltage?
Thanks!

I think 666mhz GPU setting is probably reserved for Satans minions. At the moment the only way to control GPU speed is by adjusting the voltage. This is easiest using hunds kernel (3.1 if you have problems with 3.2) and his app. Together, you can crank the GPU all the way up to 775MHz and fry some eggs on the back of your TF700 and waiting for it to go into nuclear meltdown.
I know the gpu runs hot, thats why I want to see what speeds can be achieved with limited voltage. So you‘re saying the only way to change gpu speed is by setting a higher voltage for it? Why is that exactly?

You've posted this in the wrong forum, so it will be deleted, in the mean time there is really no reason to use 1900mhz even less so while gaming. 1700mhz at max (it can go higher but you wont see much change/ if at all in benchmarks/ games but u'll see the difference in battery life)
As for gpu i run 750 mhz but again the difference between 650 - 750 mhz is hardly noticeable, gaming performance isn't great on the tf700, the tf300t doesn't look as good but its noticeably smoother with 3d
Moral of the story the tegra 3 gpu isn't powerful enough for 1920x1200 the tegra 4 wont be much better, the tegra 5 is the interesting one

Yes, that's what I'm saying. Unless you want to learn to create kernels and do all the magical voodoo these wizards do to bring us OC kernels!

I have no idea, been wondering that myself. I even posted the question somewhere about a week ago, but no one enlightened me. I really reccomend using hunds kernel and app though. There is a "gaming" option in his app that works very well, good speed without the ominous red glow of molten metal on your TF700's back panel.

Are you saying increasing gpu voltage will subsequently increase gpu frequency? (i have no idea how it works, ive never bothered to look into it but now im interested) _that or Hunds will know but im guessing if thats the case freq and voltage must be linked in a voltage table but i would have thought freq could be changed independently to voltage

I know the tf700 isnt much of a gaming tablet unfortunately, but then again, why not setting it up so that it runs games as smooth as the hardware will allow ? Every small improvement is an improvement if you ask me.
For 750mhz gpu, what kernel are you using?
Sent from my ASUS Transformer Pad TF700T using xda app-developers app
I'm using hundsbuahs latest kernel, the problem with tegra CPUs is thermal throttling, it starts around 72c on a lot of devices (not sure about the tf700) at 1900 you could find worse gaming performance than a lower cpu / GPU clock speed. Its completely up to you, hundsbuahs kernels give users a lot of flexibility as they can push the devices to the limit, I like _that's kernels personally they suited to my usage (what ever that means)
Hi all, Today I am goin' to introduce the terms OverClockin' and UnderClockin' for newbies . Overclocking and underclocking are opposite processes .
OverClock
________________
Overclocking*is the process of making a*device*operate faster than the clock frequency specified by the manufacturer by modifying system parameters (hence the name "overclocking").
| ¤ ¤ ¤ ¤ ¤ ¤ ¤ ¤ |
Over clocking of android device may increase the speed (speed of cpu) of device by using more voltage at higher freequencies .
Consequences
|i!i!i!i!i!i!i!i!i!i!i!i!i|
¤ Increase the speed of device
¤ More battery consume .
¤ More Heat produce .
¤ Risk of damage of hardware due to more heat .
Some manufacturers overclock devices to improve the speed of devuce .
Underclocking
___________________
It is the reverse process of overclocking .
Consequences
|i!i!i!i!i!i!i!i!i!i!i!i!i!i|
¤ Increase battery life .
¤ Decrease speed (system becomes too laggy) .
¤ Decrease the Heat of device .
|i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i|
Note :- Installing process of New/Custom Kernals may change the Freequency .

How about default, wouldn't it be considered a mix of two. i wonder how the manufacturers determines what should be the default value. maybe they measure it based on temps?
Ever thought about overclocking + undervolting and selecting the right scheduler/governour for your needs???!!
