When are we likely to see OC of Tegra'3?

Dev's are super awesome, don't get me wrong.
When are we likely to see OC'd tegra3'?
What needs to happen before we see that?

When it stops crapping itself as it is. lol

How do you mean?
I've not really encountered any problems with it. I have seen Dual Core clocked at 2.0Ghz.
My general question was, are we likely to oc'd tegra3's..

This is the 1st Android phone I don't feel like overclocking. I've underclocked my One X to 1.2GHz so the phone will run cooler and longer, so far have not seen any slow down.

Which ROM are you running?

Android Revolution HD 1.2.1 using SetCPU, it also works on stock rooted ROM.
P.S. I also set governor from on-demand to interactive to give better battery life.

exactly I've been thinking UC would solve heat issues, 200-300mhz will not cause a major effect
what app did you use?

But does setcpu support 4 core control? You may have underclocked 1/2 of the cores but probably not all of them

I have no idea, let me run some benchmark tests at different speed set with SetCPU.

[Q] SetCPU - Extra Info?

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

Thanks man

How much battery life can you save using setCPU?

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

I have set the governor to powersave. Is there anything else? How would I undervolt using this app?

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough

Overheating

I've OC 1,8 GHz... I know that when playing games, phone's temperature raises, but when I'm playing NFS HP it almost burns me. What can I do with that? Does custom ROM may reduce the overheating?
And which ROM is the best?

reduce your overclock to 1.4ghz...really no need to go above 1.4ghz currently

yeah, but with 1,8 GHz is the best score in Antutu...

So in the end its just about benchmark score..

Antutu means nothing......im not understanding this recent fad in basing your phone on Antutu etc etc maybe im just old school i dunno.....you asked about overheating and i gave you an answer......benchmark scores mean nothing at the end of the day....

Ok... and what about the best ROM?

search for it and install which u find its best for you

Overhaeting at 1.8ghz while you are playin a game that stresses the RAM? Are you serious??? that is your phone's way of telling you that it cant take it, reduce the OC before it blows up...!

sorry i should be straight forward and not scare people like that...

I'm running the Titanium Kernel build#4 and occasionally take it up to 1.7GHz; the handset does get extremely hot (battery temps were somewhere in the range of 50C-60C, I think) so I never OC that high anymore. It probably cant be very good for it
As for "best" ROMs, it really does depend on what you prefer, but flashing the Titanium Kernel and running the Lionheart governor seems to give the best performance and battery life at a 1.4GHz OC, for me anyways.

That is true. The CPU can withstand ~100°C but not your hand. Standard phones has plastick fascia, so you are not sensing the heat that much as in our aluminium V. The phone can withstand that much, the question is how long...
As for me, I use the phone at stock 1Ghz, and for me it is more than enough.

Overheating is a big problem even without overclocking, imagine it running on 1,6ghz...
Sent from my Renovated HTC One X using Tapatalk 2

Can't really see why you would want to overclock the One X, the phone is blazing fast anyway, 4 cores at 1.5 is enough..
But like everybody else said, the phone would probably burn up..

I wouldnt overclock my device - at least not at the stage we reached now.
Why?
a) As long as there is no way to lower the voltage this might toast your device - its a unibody, keep that in mind!
b) 100 MHZ more would have literally no effect - its a 6 GHZ device, even if you boost it up to 6,4 - you wont notice, it will just drain your battery.
6 GHZ is WAY enough...this is smartphone...I mean...seriously...its got more power than my 4 years old 1K €uro notebook...

well first of all you can't just multiply the frequency by the number of cores. I'd much prefer an actual 6Ghz single core processor over 4x1.5Ghz because it won't have any compatibility and efficiency issues. Assuming they are of the same architecture and power usage of course.
Also the ARM low power SOCs probably don't have comparable number of commands per clock cycle as an x86 high performance CPU, even if it's 4 years old.

i agree.. when the multi-core CPUs first came out intel said doubling the core number would give as 47% boost in total performance (not x2 like apple says as they do not know it) lets assume that to be %50 to make the math a little bit easier..
so basically we can make the math here as; 4 cores at 1.2Ghz (when the all 4 active the clock is 1.2Ghz) gives us 1.2 x 3/2 x 3/2= 2.7 Ghz single core performance.. this value for SGS3 is; 1.4 x 3/2 x 3/2= 3.15Ghz
and here we can say dual core at (X) Ghz gives us (X) x 3/2=2.7 thus the (X) = 1.8 Ghz.. so, if you overclock any arm9 based Dual CPU to 1.8 Ghz you get the same performance "on paper".. if you want to catch up with SGS3 we need to OC it to 2.1 Ghz which is impossible at the moment i guess..
what makes the difference here is the lower loads or multiple loads on the CPU.. corecontrol users probably would have noticed; sometimes when the all 4 core are active the clock is only 480 or 640 Mhz (even 320 sometimes if i remember correctly) .. the same amount of load could be taken care of by a dual core at about 720 or 960Mhz.. but here the quad core system stays cooler with a little less energy consumed (or wasted) (as long as all the cores are in one uni-body structure, putting 2 or 4 single cores phsically together is not the case for our smartphones) this is how apple made sure about the smoothness of the ipad 2, new ipad and the iphone 4s.. they used lower clocked 2 power vr 543 GPUs.. when the load is little they can clock down to very low speeds and share the load..
and also you can always find an emtpy core waiting for new task when the others are busy..
so, long story for short; if we were dealing with a little amount but hard processes, having a single core at 2.7Ghz would be good since the quad core design would not cut one task into 4 pieces... as long as we were not thinking about the battery life and the heat.. but since we are dealing with lots of tasks which all could be handled by 1.2Ghz power having 4 cores is better for battery saving and having an empty core for a new task to run parallel with the other running tasks in the background..

It is OC out of the box I think Nvidia OC them for us and it's already pushing itself at the very edge of what is possible for it to do based on temperature, I seem to remember Hamdir saying something along those lines once upon a time...
Why bother to OC it's fast enough as it is.
---EDIT---
hamdir said:
only faux kernel betas allow OC
big warning OC is bad for the HOX given the thermal envelope
you are risking both you battery and processor if you OC
i know you are used to OC from other devices but those had headroom, it is not the case this time, T3 is operating at its max thermal capabilities on the HOX

the snapdragon 2 on the Arc had a lot of headroom
the chipset is rated @ 1.5ghz stable!
not the case with T3 its milking the very maximum of the 40nm process
in other words Nvidia is OCing its T3 out of box because their chips are designed to survive massive amount of heat (sadly it doesnt mean the battery or other components would survive)
it is already Overclocked lol
sometimes you have to listen to the "science" of it and surrender

Depends on what you plan to do with the device. If you are going to use it for some high end gaming (Gameloft, Ubisoft, etc.) then yes, the extra .5Ghz will help increase the frame rate.
For normal use (web browsing, flappy bird, etc) there wont be much performance difference.

The 1.8Ghz should work fine for you then. It can run the simple stuff with no problem.
Sent from my ASUS_Z00AD using XDA Free mobile app

The 1.8GHz version might even have better battery life because of that and because it powers half the RAM.
The cpu is quite powerful so most the time the phone runs at lowest frequency step of 500MHz anyway.
I have the 2.3GHz version but I'm actually running my phone capped at 1.8GHz anyway to see if battery life difference is significant.

I have the the ze551ml variant with 1.8 cpu and 4gb ram. I think that the device run smoothly also with heavy games.. and you have the advantage of lower consumption of battery...

You need a custom kernel only for overclocking. The stock kernel has limits built in. As long as you stay in these (usually stock clock is max), you don't need one. The actual clock speed limits are written in a file which you can even change manually (needs obviously root). For example:
Code:
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
cpu0/cpu1/cpu2/... are the different cores.

No, not really. The CPU is pretty beastly and usually runs at the lowest frequency step of 500MHz or the next step up (583MHz) anyways.
It rarely goes above the minimum speed except for touch events (when frequency will be temporarily boosted in anticipation of activity) and heavy usage like Web video streaming, gaming etc.
I haven't seen any performance degradation with my games and emulators at 1.8GHz vs 2.3GHz.
So overall the battery savings aren't dramatic and really not so noticeable except for heavy usage anyway like gaming. I also have the touchboost capped at 1GHz from the stock speed of 1.33GHz. Again, not huge differences but just little things that add up.
As I said, the CPU is already beastly and efficient. It's really the older screen tech used for display sourcing that has the most impact to battery life.
