I already postet this in the Atrix 4G section, because they have a thread there about this topic. But they are discussing more about the locked bootloader than about overclocking and as we don't have such a thread here, I will start this one.
Perhaps you think overclocking actually does not make much sense on this device atm, as it is really fast, but I always like to get most out of my hardware that is possible.
I dont think, I would enable overclocking for everyday use now, but it would be cool to be able to do so if needed. At 1200 MHz as Nvidia had planned for the Tegra2 3D the Phone would for sure even beat the Omap 4 in Optimus 3D.
I am totaly new to Android and also to Linux, so I am not sure if this is helpful, but I have seen something very interesting in the Optimus 2x review at Anandtech.
I dont know where these variables are stored and what is needed to, but for me it looks as if we are able to change them, overclocking should be possible on the Optimus 2X.
It would be great if some oft the developers here could look into this when the Optimus Speed finally has been shipped…
I was wondering the same thing. So i checked other Tegra2 powered devices. And as far as i know none has been overclocked yet. Correct me if am wrong.
So far no overclock is needed since this phone is reaaaaaaalllly fast.
But I am sure as soon as it needs some extra power developers will figure out how to do it
Michael Huang (author of SetCPU) has just overclocked the Xoom tablet today. Now, while the Xoom is a Tegra2 device, its kernel is (apparently) Google based whereas others are nVidia based.
In overclocking the Xoom from 1GHz to 1.5GHz though, he saw about a 1/3rd increase in performance on Linpack and Quadrant. Looks promising so far.
Watch the video here http://www.youtube.com/watch?v=cLNjHyAi8BI and follow Michael on Twitter here: http://twitter.com/coolbho3k
The Reason to Overclock the Atrix in my opinion is as follows
The Linux Based Webtop is slow in reviews
So when pluged into mains power it would be very usful to overclock the device to make the most of the webtop with less lag issues making the device far more usful if you need/want that feature.
Maby possible to make a custom dock (stick fan on it) and clock higher
I'm more interested in underclocking, especially when screen is off with a screen off profile in SetCPU. What do you think is the lowest possible frequency I could set it at?
You can put all the way down. I use the same settings in both my N1 and the 2x. Saves some juice. What I really want to see is custom kernels, pref undervolted if its possible.

According to the SetCPU changelog, overclocking/underclocking is now possible:
2.1.1 - Fixed an issue with profiles backup in CM7.
- Added support for the Motorola Xoom, Atrix 4G, and other Tegra 2 devices.
- Fixed various bugs.
- Tablet optimized UI and more profiles coming soon!
2.1.1a - Fixed the 0 MHz display issue on some devices.

How can you overclock with SetCPU then on o2x? Believe only the powersaving underclocking on demand is working.. overclock needs more work i believe.
The Xoom has been overclocked, but apparently the kernels are from google, which made it easier.
If anybody knows more about this, please correct me
The kernel must be adjusted to make overclock work. I got to read myself into this, but perhaps someone else knows already everything to it .
GPU
i wonder if the gpu can be overclocked, would be nice if it was possible too just OC the gpu and compare the results. Or do you think that the CPU and GPU clock speeds are somehow linked???
Any thoughts?
bumping cause im curious. Can any one please answer ?
well this is arm so id day they are linked
are we able to read the clock speed of hte gpu. does is change?
Look at the date mate
The GPU is not linked with the CPU. The GPU is overclocked in different kernels. Spica's kernel allows on the fly overclocking of the GPU.
After having this device for over a year, the only time i needed OC is for 720P Youtube or Youtube HD app. No OC on the GPU has ever been needed. Yes i have been playing around with 1.2 and 1.4, but they just consumed battery more than giving a better experience. I would go so far and say undervolt it and put it on 900Mhz.
Cyanogen 8? Is this next? Or is this in the works? Also is 2.3.5 next and would it be numbered a different version when Ice Cream comes out? Also is anything coming from the devs to overclock to 800 yet?

It's been done. So very very few phones are even stable at 800, and those that could generally performed worse in benches at 800 than at lower clocks. Many of these devices bootloop above 700.
Cyanogen 8 will not come out yet since will most likely be ice cream sandwich. I am not even sure is 2.3.5 will even come out and no the devs can not overclock this device to 800mhz because is 768 is the limit of the processor. Most people's phones do not even run that smoothly at 768 anyways. If somehow the dev found a way to overclock it to 800 (impossible btw but this is just a what if kind of statement) since the processor can not handle 800 it would just overheat the thing and cause crashes.
Also, on a side note, this should not be in the Development section. This should be in general or Q&A
This belongs in Q&A for future reference.
CM8 will be next, obviously. It will be based on Ice Cream Sandwich, so no, it won't be in development until ICS is released to AOSP so that the CM team can start using that code. 2.3.5 is an update coming out soon for the Nexus S 4G that fixes wifi and network speed, as well as adding more secure NFC for Google Wallet. It won't really affect us when it is merged into CM7. ICS is expected to be Android 4.0, but it could be 3.5 if Google decides.
There is a kernel that goes over 800Mhz, but anything over 768Mhz can be unstable on some phones. I tried it and there were no real performance gains, but battery life was a lot worse. Performance was actually worse at the highest CPU clock, in my experience. Just stick with 768Mhz. It's stable and chances are that you can get even better performance at a lower clock. I get better battery and performance at 633Mhz. It all depends on each unique phone.

I can confirm that the Godmode kernel was able to push some phones, such as mine, past 800Mhz. Although I had a faster processor speed, my battery would drain incredibly fast as well as overheat. Even though I never hit a bootloop with the kernel, the battery life, overheating, and loss of performance kept me away. Sacrificing too much for having a faster processor speed. Normally I overclock to about 729Mhz and have great battery life, speed and performance in conjunction with a min of 19Mhz and a smartass governor.

Yup, I'm at 806 - 19 ondemand while posting this and I can already feel it slowing down a little. 729 - 19 on demand is my best setup. I've tested a lot with trying higher setups than that but so far 729 seems to be the best for battery life and performance on every rom I've ever tried

Correct me if I'm wrong, but from what I've noticed is that newer Hero's that were sold with Eclair as opposed to the original Donut, when I bought mine, are not able to reach those higher processor speeds past 691Mhz.

i bought mine at radio shack back in september and it was still on 1.5 and ive never been able to get over 768mhz without it freezing and bootlooping its different with every hero.
i stay at 352-691 ondemand and thats plenty fast for me
Mine was running 1.5 also and it will run fine at 768 but battery life suffers so I usually run at 352/710 and battery and performance are good (depends on rom kernel)
Where can I get the godmode kernel ....

Hey rubyknight,
just wondering why 19? Ive seen people do that but can the processor really ever do anything at 19? if so, doesnt it affect stuff like wake. Im trying it now just to see for myself. Ive been playing with a really high min value between 480 and 576 with the high at 748 and it actually doesnt only seems to affect battery life a little, both on the .29 and .35 kernels on jaybobs roms and on OMFGB.
Thanks

so update, ive run it at 19/768 on demand all day and after 11hrs 13 min its at 60% thats not bad for my phone! and there was almost no performance difference. Just the slightest UI lag... this is on jaybobs 7/8 with the .29 kernel, with background data off. And my regular usage which is not a lot. but for me its good. i wish I had tried it ages ago.

I believe that you can set the ramp up frequency and that may help with the lag. Setcpu, advanced settings, I think?

As the thread title, when will we see kernel modules to allow overclocking/undervolting to locked bootloader devices? Im surprised I've not seen any mention yet!
I'm working on something similar to the Milestone overclocking module that could be loaded at boot time. Currently it is possible to overclock the OMAP4430 present in our phone but it doesn't persist through a reboot and to be honest, is not very "noob-friendly" or robust as it involves calling kernel functions in userspace and requires the throttling to be set to "performance", basically running at full-bore. I just haven't had time to devote a full day to it yet but will share my findings as soon as I can.

I thought I'd replied to this! Damn Opera Mini I did ask about VSEL settings? Would that be a possibility? The major bonus of clock tweaking/voltage tweaking would surely come in the form of battery life since at 1ghz dual core the power is probably meaty enough.
when i use 729 or above my Cpu stops working and its Reboot automaticaly any way to fix
Unfortunately you can't fix it. The overclock ability of the cpu is different in each phone. Some x8 can run on 800+ MHz, some can't reach frequencies over 700MHz. Basically the SoC (the cpu, gpu, dsp and some other device) contains millions of transistors, but the whole chip is only ONE small piece of silicium, the transistors made by litographic and other complex (and expensive) procedures. The overclock ability depends on the material quality (damages in the silicium structure), soldering quality between the core and the casing, etc. So, no existing rules to the overclock, if you lucky you can reach high frequencies, if you unlucky you can't overclock.
Note: under the manufacturing procedure the chips get a selection after testing, the highest quality 7x27 chips marked and sold as 7x27T with default 800MHz.
There is an app in the market called No Frills CPU Control: https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
It will automatically change your CPU frequencies during boot to save your phone from hard bricking.
Anyway CPU gets overheated by overclocking as more amount of power comes in to it than what is required. So as a long term effect your CPU will die out and also your Battery too. So I would say to use a faster rom and dont overclock the CPU to very high frequencies.

You are using stock kernel?
Overclocking more than 729 is not possible for stock kernel...

governer also matters, I always use smartassv2
As someone wise already stated, better using something like FroyoPro which is blazing fast compared to any GB rom instead of overclocking.
I can do more with FroyoPro than anyone running GB, ICS or JB roms.
It's just simple - lighter code takes less cpu cycles therefore it is quicker.
GB, ICS and JB roms really are a waste of time once you've tried FroyoPro.
The other roms are really only good for proof of concept - not for everyday usage.

I compared it with iXperia 8s rom before, froyopro is better @ one of 3d tests(just 2 fps better)
Other test were like iXpera & minicm7
Remember it's froyo & they are ginger ,they can run newer apps .

It also depends on the kernel you are using..Alfs is better in this aspect..but too much overclocking is not recommended.
if you are using custom kernel ,under CPU settings, select the frequencies you desire and do NOT select "Set on boot" . Even if your phone gets rebooted due to overclocking the default values will be applied at boot. This way you can avoid problems.

please read 2nd post by pilu. that's the best explanation. it's a hardware limitation, and it does NOT depend on the kernel.
[cAs]
Partially depends from the kernel too. The cpu clock is not only a simple value: xyz mhz. In the kernel this is a little bit complicated (pll frequencies, dividers, multipliers, voltage level, etc). Different kernels use different frequency tables, the results can be different, this the developer choice who can set different bus speeds (axi, ahb), base pll, voltage to every clock speed. You only see the frequencies in the different kernels, what is same, but the same speed maybe generated with different method.
So, the cpu overclock ability is 90% hardware limitation and 10% other things. Usually if you reach your own max speed with a kernel, the probability of higher speed with another kernel is small, the typical difference is nothing more than +/- 1 multiplier (+/- 19,2 mhz).

Hi guys,
OUYA need some good developers or really good one developer. Where are the times when I had HTC Wildfire and with this phone was everything possible a lot of developers. OUYA kernel looks quiet bad. 720p doesn't work and gamming at 1080p isn't smooth. So we need overclock GPU (600MHz+) or make working switch to 720p. If you think you have had 720p already, check this at CPU-Z or Nenamark 2.
Goddamn my MK802+ with ****ty overheating Allwinner A10 is switchable to 1080p and 720p!
If is anybody here what can improve kernel or resolution please do it. I think we the OUYA users can donate good developers.
I'm still at it, but very little time to get into custom kernels

why don't you use forced resolution mod in Mod Collection for Xposed Framework? should do at least the resolution part.
and for CPU/GPU:
I know for sure that tegra3 is build to be able to operate at higher temps and should be safe until ~75-80 degrees celcius.
With that in mind and the fact that we have active cooling i think oc should be possible, but would it be useful?
Stock CPU speed is maxed at 4 cores @1700Mhz, GPU is set to max 520 Mhz.
In theory it sould be possible to get a safe max for gpu at about 650Mhz, but you would notice the difference only a bit. Pumping it up to lets say 700-750 (technically possible but might become unstable) will bring just heat, noise of the fan and almost no noticable difference.
I started the kernel and did try some tweaks to get better IO-speeds and also tried to implent gpu-oc, but back then this kernel renderd my ouya useless and i had to order a second one. Since then and given the fact that this year had a couple of bad suprises for me and my family i still got lot of other stuff to deal with, whenever i got time and feeling like i want to, i get back to kernel development and try to a) unbrick my first ouya and b) read, learn and test some stuff. (i'm ne to all of this as well)
to this point i have nothing i would want to share, since it doenst give any pracital improvements to existing kernel

With this Mod app you can't get 720p your TV say that but if you run benchmark you will see 1080p a score like 1080p even your TV say 720p. Only way is use Tegra Overclock Ouya, you will get 720p but not fullscreen. In becnhmark you will see 720p and much better result than with 720p in this mod app.
Possible max for this GPU should be about 650MHz as you sad, I think it will give you few more fps at 1080p even more at 720p. But max cpu clock is 1.6Ghz for all cores only for first it is 1.7GHz. Check it with CPU-Z.
So first goal should be 1,7 on all cores. Shouldn't be to hard to accomplish.
