I've just rooted my Vivid and was disappointed to find that I can't overclock it. SetCPU has it as 1.2GHz and no option to increase it.
Why is this?

Overclocking may cause instability which is likely why it isn't enabled. In other words, stock kernel had that function locked. To get overclocking ability, you need to flash a custom kernel that has overclocking function

Thanks. However, the HTC Velocity, which is the Vivid, but in Asia/Pacific, comes as 1.4GHz stock. Surely that would mean it's stable to go to 1.4GHz?

I think Korean version Raider comes natively at 1.5 GHz, but... since the Vivid's manufacturing only needs to hit the spec of 1.2GHz, it is likely that quality control does not check for stability at 1.5. This is not to say that it cannot do 1.5ghz, just that there may be a few that might have some issues because it is only guaranteed for 1.2ghz.
I personally have no issues running 1.5 and slightly beyond, but I've also seen an user or two not doing well at 1.5, so it is a case of your mileage may vary.

I am using Setcpu on my motorola droid with rooted FRG22. Why wont it let me overclock it higher than 800mhz??? I'm kinda new to doing this and wondering if I'm doing anything wrong. Thank you
[A] Overclock answer
Yes you have SetCPU and your phone is rooted. However, you're missing one more piece to the puzzle. In order for you to clock over 800Hz you have to install a kernal cooresponding to the voltage and what you want to overclock it to. I recommend you googling(haha) p3designs and choose a kernal you want to try. Instructions are on the site as to how to install. I currently have a low voltage of 125Mhz overclocked at 1Ghz. Hope that helps
Question for you Stephen, with you running 1.2Ghz on your droid, has there been any istances of freezing thus far? I was tempted to go higher, though I stuck with 1Ghz to be safe.

The right approach to overclocking is not how fast can you go, but how low can you tolerate? Most Droids are stable to 1.2 ghz. Some can go higher, some can't. I'm running the "stock" 1ghz kernel that comes with Sapphire rom. However, I have it choked back to 800mhz. This gives me 36 hours of battery life on light-moderate use, (3G off, wifi on) but also lag-free performance.
This is chevys 1.25 medium voltage, only reboots were with watching movies online.

I understand what you mean. I've done the trial between 800Mhz and 1Ghz. I have emulators now and I liked the performance on the 1Ghz more because of the speed, so I kept it on 1Ghz. I haven't had any battery drainage issue and all. I liked my low voltage 1Ghz kernal.

Is this the site you tried accessing the kernals? I did a test and downloaded the kernal zip fine.
That does sound impressive. I'm curious to try that out even more so now.
Thanks for all the info on here that I used to root my NC and sideload apps. I was wondering since we have seen that an OC is possible during the root process, what is needed to make an overclocked kernel for the NC?
The stock kernel isn't going to allow it, but it should be possible on custom kernels.
Then again I may be completely talking out of my ass.
Well we were waiting on the source but thats been released sp now we need someone to build a custom kernel ...and ofcourse i can and probably am talking out of my ass but i think that sounds right

See this post. I tried it one more time and I think the touch sensitivity is just my imagination. As far as performance is concerned, it doesn't seem to make any appreciable difference.
The 3630 and 3621 voltages in the power profiles probably need to be mixed and matched since the normal 3621 profile is at a lower voltage at the same speeds as the 3630.
Why has nobody overclocked the Droid 3 yet? Is anyone working on this?
This phone has so much potential with the duel core processor.

From what I understand, we have limited access to kernel modifications. I don't think the bootstrap circumvents these problems.
I'm still hopeful though.
With the locked bootloader, custom kernels aren't possible. However, it can be overclocked, through the injection of a module. I'm not quite sure how it works, but once someone does that, we can OC. They got the Droid 2 and X to 2 ghz.

With kernel modules is possible, was already done on milestone 1
I would be more interested in undervolting. Can this be done with the injected module or is direct access to the kernel required?

You can do it now with SetCPU. Be very careful though, Moto used a weird governor on this called moto_hotplug, when root was first available and people undervolted some reported going too low and not having enough power to turn on the screen. I wouldn't set the max below 600MHz until more is known about this governor, and even 600 has been a little low for me at times.

Usually Motorola phones are power hungry because the 3G, not because the cpu consumption, the gain in battery life available trough undervolt is usually limited.

I appreciate your response, but I think you misunderstood my question. I want to undervolt, not cap the frequency. For example, if the SoC operates at 1.3v at a clock speed of 1Ghz, then I would like to try and drop the voltage to 1.2V at 1Ghz (higher or lower voltage if viable). I don't think this can be done through setcpu, can it?
It's possible to overclock right now but the process is not user-friendly. I've been trying to write a kernel module to simplify it and make the changes appear to survuve a reboot but haven't had enough spare time to figure it out entirely. Check out this post by yang.felix, he found the proper register to manipulate on the XT862 but it isn't easy for the average user; I'm trying to see if a similar approach to how the original Milestone was overclocked can be applied to the XT862/XT860:

Is there any gpu overclocking app for captivate.
Sent from my SAMSUNG-SGH-I897 using XDA App
Not for the stock kernel. You would need to change to a different kernel that supports overclocking.
No, there is not a way to oc the gpu, just the cpu.

Doesn't MIUI allow this with glitch? or is it that glitch has the gpu already oc'd by default... Dont remember

I'm far from an OC expert, but kernels supporting Live OC allow you to OC the bus, which affects RAM and GPU. However, I thought that it was really just increasing RAM speeds, which in turn helped the GPU a bit since it uses the same RAM. That's why if you overclock the BUS you start getting visual artifacts: because the data was getting corrupted in RAM on it's way to the GPU.
Or I'm out in left field, which is never out of the realm of possibility.
I have no clue. I just remember reading something on glitch v13 on gpu oc and MIUI. Never tried it, don't know the theory. Was just asking couse i remember reading it xD

How do you know which kernel supports OC CPU \ GPU?
Also, I guess there are some apps which let you OC your CPU \ GPU, aren't they independent of the kernel? (I might be completely off-track here, but I had to ask)
I recently flashed OneCosmic's ICS ROM and Nushor's kernel (v3189) to my Captivate.

A custom kernel is required to OC anything. GPU over clock that is user control able requires a kernel that supports live OC.

I've been a reader of this forum for a while. I've finally regained root after losing it during the update. Thanks Marty for the root exploit. The main thing I like to do with root is overclock. Has anyone achieved this? I see benchmarks that show it has been done on the Bionic running JB. Thanks!
Anyone? No one? Will the method they're using for the Razr work?
Has anyone here overclocked a Bionic on Jelly Bean? If you have, please point me in the right direction. Thank you.
As far as I recall, 1250mhz is as high as you can get on this hardware. You should be @ 1200 already, so I imagine the difference would be negligible.

I was running 1370 stable on ics. Just need a kernel I think.
Have you tried this?
http://www.droidrzr.com/index.php?/topic/16813-[KEXEC]-Code-Kernel-4/24/13
I couldn't get it to show the higher frequencies but maybe you'll have better luck with it
It lagged for me, it defaults the min to 100 and couldn't get 300 to stick.
Others have had better luck

Overclocked at 1300 right now
Currently I am overclocked at around 1300, 1400 made the device freeze. I achieved this by installing a custom ROM, if you go to Motorola Droid Bionic > Droid Bionic Development > Blurry 2.4 and install that rom, it has built in kernels that allow overclocking.
Sorry for being a noob, but how do you overclock it? And is their a difference when its overclocked?
Sent from my DROID BIONIC using xda app-developers app
Over clocking to my understanding is a feature that some kernels have along with additional scripts added. I personally use Motomizer Expert to set the CPU values to above normal (my values originally were 300, 600, 800 and then 1000) I have it overclocked to where my processor runs at 1300. I then set the value to the maximum using SetCPU. All it does is make your processor run faster than normal, making the phone snappier and faster overall, not by much, but enough to notice. I hope this helps, and keep in mind I am also a n00b, so if I am wrong, I'm sorry and maybe someone more knowledgeable can help you.
Thanks for all the responses. I'll try changing the kernel first, if that doesn't work; I'll consider the rom. I like the way everything runs with Jelly Bean, I just love to tweak.

The kernel is difficult to change till the boot loader is unlocked (most likely will never happen). Of coarse kexec kernel is the only way for now.
More Input
I have tried the Kexec Kernel, unfortunately, it allowed me to underclock to 100, but it wouldnt allow me to set any values about 1000. That is when I started looking into OC'able ROMS. and Blurry is the one I liked best. AOKP is nice, but it didn't have the kernel built in. I have not tried Liquid Smooth and CM 10.1 was just not for me. Hope this helps.
