With the console being easy to tinker with are there any plans to release improved air coolers to allow overclockers to push the boundaries further.

I have previously gone to great lengths to get the best from my PC systems - I lapped (fine sanded the top) off my q6600 and 1055T CPU's and did the same to a Gellid Tranquillo and Tuniq Tower CPU Cooler. This resulted in the chips running at around 10 degrees cooler when overclocked due to the improved heat transfer from a perfectly flat surface.

I would really like to know more about the Tegra 3 chips limits - methods to use to overclock it and also hardware tricks - adding extra fans, changing the thermal paste and modding the cooler,etc

Has anyone risked tinkering with any of this yet and if so what results have you had??

I found this link regarding a Tegra 3 equipped Nexus 7 being pushed to 2Ghz so I think that would probably be a good first target - as the Ouya is not as tightly enclosed it may go further 2.2 - 2.5ghz may be possible with improvements to the cooling.

I also wondered this :P Yes the nexus 7 got to 2.0GHz but the HTC one can only manage 1.8 I believe

If you could make hit even 2.1ghz that would be amazing, also if you're going to give the CPU a try, try the GPU as well :p

Has anyone been working on overclocking this thing? I would love to see what we can get this baby to do! I might even buy a 2nd one to try and do oil cooling on it to really squeeze every last drop of performance out of it.

Yes. There is no "dev kit" for OUYA. The OUYA itself is used to develop.

I wish OUYA had kinda pushed the chip further, maybe overclocked it to 2.0ghz, although I suppose its not too badly powered at the minute. To be honest I'll probably have to wait till I get my unit to see how it fairs.

Can you not shimm the cpu and gpu with copper plates and thermal paste?And even if it can't be done with the current design then surely there is a way to manipulate this to accompany them,also using a higher rpm fan that is silent would work as a good combo to this,then you can overclock the f@ck out of it without heat being a worry,obviously the silicon would be the biggest worry then as in would it take to the changes of the overclock being high and stressing it,would it stay operational at all?As i hear that pc cpu's tend to fail silicon wise at times as the silicon can't handle the stress,the shimming is a laptop overheat prevention trick i use at times on repairs.I commonly use an average of 1mm down to minimum of 0.8mm if that helps.I have yet to recieve my ouya i only ordered it from game yesterday as i live in the uk the release date pending is 25th of june all going to plan and schedule.But i shall certainly take a gander at the idea i just threw out there to see if a mod could be advantageous in the future when my warranty expires i shall give that a go then.Good paste and neatness is the key to a successfull shimm job though so make it neat and tidy if your trying,the cooling plate must be perfectly even to the shimm positioning and paste applied between chip/shimm and shimm/cooler.

I have a Asus TF700 that has the same Tegra 3 t33 proceesor as the Ouya. We have a custom kernel which can be installed along with a custom stock rom. The kernel allows for the cpu to be oc'ed to 1.9 but after about 30 min of intensive game play it gets very hot to the touch (154F +). Of course the Asus does not have a fan. Just a fyi.

A copper shim...I'm definitely going to try that on my old GTX 560ti that started overheating after I installed a factory backplate. I bet it wouldn't be hard at all to apply a slightly modified cpu hydrocooler to the Ouya. It would require a custom case, but I bet it would work quite well for overclocking the little bugger. one of the smaller ones would probably be fine. http://www.gizbot.com/files/2012/11/corsair_Hydro-Series-H60-liquid-CPU-cooler-1.jpg.


I wonder how long it will be before we see a tiny liquid nitrogen pot on an Ouya...

Today I rooted mine and made some tests with Tegra Overclock (https://play.google.com/store/apps/details?id=com.tegraoverclock&hl=de)

I noticed it is far from the trottling Temperature limit with a peak around 61C where as throttling starts at 75C.
EDIT: I managed to force it up to 70C. Maybe there is not too much potential before running into thermal throttling!
(fyi you can see the temperature in /sys/class/thermal/thermal_zone0/temp)

So then I started the tool and it works allright.
The CPU speed you can set with this is 1.7GHz -> stock clock
The Voltage can not be changed with the stock kernel -> stock voltage
The GPU clock can be changed with the tool but above 520MHz mine immediately froze -> stock clock

So what is the conclusion for my unit:
I'd need a custom kernel with overvolting and overclocking ability. Right now overclocking makes no sense, but maybe something will surface on xda soon!

Thanks for that information, sounds like we need a few custom pieces of software before we can OC then.

If at some point we can get an ouya to OC at 2.0 safely on stock fans then I would be all for it, the little ouya needs extra juice.

That is because you run into thermal throttling. It is quite common in mobile devices.
Also makes me doubt it is worth it for Ouya, since i hit a 70C already without any OC and it starts throttling at 75C.
But I think I will try to limit the CPU and overclock the GPU, maybe it helps with some games.

Doesn't matter. With no power off to recovery boot or fastboot, you can't adb to the unit to upload an update.zip file. If anything at all happens to the kernal, the darn little thing just has a hiccup, then you may as well just add the Ouya to the landfill, unless by some miracle you manage to get support to respond, AND they agree to an RMA.

Bad design. Just Bad, Bad design.

Then i will be assuming with this,then why not us es file manager to export or copy the entire ouya file system and simply copy it back like for like if it still is readable as a bunch of folders (file tree)

Because it won't boot, you can't. The only way to use ES File Manager is while the ouya is completely up and 100% functional, after passing the required usable internet access and credit card entry checks. You can't boot into fastboot and upload a system image. You can't boot into recovery and use ADB to push and pull files. You can't add these because the bootloader is locked. You can't use the test pins to talk binary to the flash because it's encrypted and they won't give us the keys.

Basically, OTA update goes bad, say hello to my little brick. That's why there are no custom ROMs for it yet and development is so slow. The console is anything but open. In fact, is the single most closed Android device in existence.

Hi guys i am back and have managed to shimm the ouya whilst breaking a leg on the heatsink plate in the process but it is stable enough without it now although i tied it off with a plastic coated wire cable tie so i could twist for shape and tightness where it is missing the leg and it does the job,to be fair i realize that these ouya's run pretty high temps on load,but can vary on idle if background tasks are not properly closed making huge differences in temp change in a nano second.I used a 1.5mm deep copper shimm and i have also got superuser loaded but not in a fully rooted way making it useable none the less.I cannot bench test the unit as i have not found anything allowing tests like prime95 for pc.I have been tryng to load cwm for it but it does'nt load it when it does a reboot there is ouya followed by ! symbol under it ,so that's a major bummer realy.And also it will not load google play store but will run apps like cpu master pro. Antutu benchmark works but won't complete a full graphics test though, it just crashes part way which is another bench testing obstacle,also it appears a special kernel must be used to clock a tegra 3 using the manufacture overlcock app,unless someone finds a way around it for the ouya? Also in the cpu master app the mhz are set to maximum which is 1.7ghz each core and i would not know what to do in setcpu application to alter freqency and other features to give more out, if it even can at all and/or with my root type, although the cpu can not go higher in apps so far it is adjustable in that app,i have never in my life overclocked anything and would love to know how the whole thing works in layman's terms for android if anyone can assist me here would be appreciated, i'll drop a load of picture links eventually when i can get some results from the temperature checks i plan on performing during stress testing the ouya.As far as the shimming goes though the temp stays absolute max of 51c i have seen after being on for 24hrs and it now seems lag free in every game i play no mild stammer ever and it does'nt glitch ever in the ouya menu now either when scrolling it is extremely fluent , all seems improved performance wise as a result of the shimm so far so good.Oh almost forgot the legs of the heatsink are soldered to the board (b@stard) and is going to need some temps to remove it a good iron (variable) should suffice. I would just like to add,remember the day you touch the side of the ouya when it has been on for a couple of hours and you think to your self how is it running still because you could damn near fry an egg on it,well after the shimming it no longer gives any heat on idle what so ever and has'nt done sat left on for 24hrs :)

Right guys i had a look on youtube on and off at times yesterday and found this (http://www.youtube.com/watch?v=weNtKFtE6Nk) benchmark for ouya using antutu benchmark and the users results are 13961,so i made a youtube channel with a video of the results and here's my results guys http://youtu.be/ox8JKyNuzVA as you can see mine seem higher since shimming the cpu, i am sorry for the reflection that looks like a ufo it's the lounge light shade reflecting on the tv screen. :)

Not really sure its a good idea. Im too lazy to find the article...but about a year ago in August someone used a Nexus 7 and an experimental custom kernel to blow away some benchmarks with the Tegra 3 overclocked to 2.0 Ghz. But it was extremely unstable. We are already operating at 1.7 Ghz. A GPU overclock might be more feasible to get additional frame rates/performance. Assuming the system doesn't fry and you end up with a $99 ball to play catch with the kids.

On my tegra 3 t33(same as Ouya) Asus Tf700 tablet I have installed a custom kernel that can oc to 1.9 for use with some graphic intensive games but I can only use it for about 30 minutes before it gets hot and then I have to shut it down so it can cool down. The Asus does not have a internal fan like the Ouya though I have read the fan does not do a very good job with heat control at 1.7 on some units.

I can not even recommend looking into OC due to horrible issues with ouya and cooling...

Great example would be of downloading Order & Chaos... I was pulling temps while it was downloading ( due to it locking up all the time ) and saw I was hitting thermal peak before the ouya locks up in order to try to save itself from bascially thermal damage.

I really wonder how they failed so bad at cooling design.... It's almost as if they looked at the design on paper and said "Looks good to me! LETS DO THIS!" without actually testing.

This simply means applying copper plates to the cpu and or gpu to make it/them withstand heat better
