What is the highest MHz that i can go up to without risking my phone too much? My ROM and Kernal lets me go up to 1920 but thats probably not the best idea.

you have reason.... NO GOOD IDEA lol
in a kernel thread (a lot of time ago...) i was read... that was not recomended overclock avobe of 1600 Mhz... And atention important!!! don´t underclock down 170Mhz more or less (because can be the devece cannot exit from standby mode when you unlock the screen....) i cannot remember what was be the thread but i really believe that there is not a concret limit for overclock....
sure that it´s not good any tipe of overclock for improve the performance...
but i have a hero overclocked at 714 mhz (factory stock at 525 mhz) since 2009 and NO PROBLEM never,,,,
and my DHD overclocked at 1200 mhz (with a quality kernel in mode smartass)
and underclocked at 245 mhz more or less and no problem....
judge by your self but use the common sense... cheeeers
At the moment i have it on smartass to 1459 max and 230 min and it seems fine. Do i just judge it on the CPU temp, and if it stays quite low (Around 30c) then im fine?

it depends buddy...
maybe its well.... the normal temp. of my batt. in use is 33-35º (but here in spain we are now at 30º !)
but my question is... are you really sure about its neccesary overclock our DHD?
I think that still DHD supports well all kinds of software with 1 GHZ of power...
maybe for a future thinks....or for gamming but always u can overclock for use a game and then return to 1ghz...
it´s only a suggestion... maybe another OP uses the processor of different mode...
The overclocking limit differs from device to device, so there is no general answer.
As a rule of thumb, when you start getting random revolts or crashes, you have gone too far.
If you want a more professional way, just slowly turn the clock of your CPU up and run a stress test after each time. It takes a bit more time but should get you pretty good results.
How long should i leave the stress test running for?
The reason i want to overclock it a little is that it just runs a bit more smoothly with it over clocked a bit. Just everything in general seems a bit better to use, its not really for gaming etc.
is it possible to overclock above 768mhz? my phone never gets warm and battery lasts 2+ days, completely stable at this speed, i want to learn how i can edit a kernel and increase the cpu voltage ever so slightly and increase max cpu clock and see whats stable, could you help me?
i think you will just start to get kernel panics if you try to go much higher .
i have another phone (lg 500) also with the same arm6 cpu that comes clocked at 600 from factory. i have the option to oc to 825 with custom kernel but it always panics at 806 and is stable at 787.
So i think if you want a faster phone go buy one

lol the chipset for the wildfire is MSM7225 but the cpu is arm6/11? on half of the sites is arm6 the other arm11..
Hi I have mine set to 710 and any higher starts getting random reboots.
But overclocking any higher than 768, your risking a chip melt or definitely shorting its life.
Can someone tell me where I can find over-clock able kernel for my international One X? And what is the biggest clock speed on ONE X?
At present faux kernel can oc depending on what variant CPU you have but max at 1.6ghz

I suggest you flash faux's kernel.
It can oc to 1.6GHZ for most user~
and it support s2W!
I expect many users will be aware of this information, but just in case you aren't.
Anyone overclocking should be aware that this will usually lead to higher power consumption which leads to more heat produced and lower battery life.
Especially if it is necessary to overvolt to acheive higher clock frequencies with stability.
Power consumption is proportional to Voltage squared, so small increases in core coltage can result in larger increases in power consumption than mught be thought.
Needless to say this can have negative impacts on battery discharge time and overall life (due to higher temperatures).
Plus there may be some throttling back of frequency if high temperatures are reached. Also possible that frequency may be reduced to 1Ghz maximum when battery voltage is low (i.e when discharged)
Hope this is helpful (first post here)

CPU throttle starts at 85c with thermal TJ-max of 99c.
also there is many debates about this, higher speed need more power which drains battery, but that said it means work gets faster meaning it can idle faster saving power, same the other side slower speeds save power but take longer to get work done using more power.

Go to Faux123 and read the opening post

it will teach you about Tegra 3 variants.
Flash Faux123 latest kernel to know what variant you have.
You can have 1.5ghz quadcore minimum, except if you have the poor variant0 of the Tegra 3, and 1.6ghz quadcore max if you have variant 3
So the overclocking you can achieve depends on your Tegra 3 variant, whatever the kernel, don't trust the figures in kernel threads titles, they just give the max if you have variant 3. And the majority of people have variant 1 so limited to 1.5ghz quadcore and there's nothing to do about it, no future kernel can change the way your CPU was manufactured.
Just, SetCPU can display 1.6ghz or more, but if you have variant 0 or 1 it will never use it (CPUspy will say 1550 and 1600 are unused frequencies)
Variant 1 can go upt to 1550mhz but not for quadcore, so who cares....! Same for kernels claiming up to 1.7ghz, it's in single/dual core, so once more, who cares?
What is important is what max speed you can achieve in quadcore, nothing else, and the limits are clearly defined by your Tegra3 variant
"all chips are not created equal" was a silly bull**** invented more than one year ago as an easy answer to noobs claiming they couldn't overclock their dual core at their max. Now, on the One-X and because of Nvidia unstable quality"all chips are not created equal" is sadly the truth.
PS: wrong=> to say that overclocking means more voltage, undervolting a custom kernel a little can surprisingly reduce heat when you push your CPU to its max,I can have both 1500mhz quadcore and less voltage than stock, as well as less heat (I was surprised, really, on the Sensation I had always found undervolting kinda useless)
PPS: true=> thermal throttle will always come pretty soon and reduce your max speed......

Your argument makes sense, but unless the governor is very efficient at controlling the CPU speed very quickly, in most cases your argument doesn’t hold true. For example when playing a game or running a CPU intensive application (where overclocking has any use) the processor works at full speed for the duration of the application.
EDIT: Frankly I don’t see any point in overclocking a phone like One X. I don’t play many games, but the few games I have played ran very smoothly. And if people are overclocking because of the (barely noticeable) laggy UI then overclocking is not a real fix anyway. Installing a custom ROM (perhaps JB), a different launcher, tweaking background apps/services are some of the more sensible and effective things to do instead.
No disrespect to the devs who are working on overclocking, but IMO HTC and nVidia must have spent a considerable amount of time and effort designing the CPU and deciding the optimal operational parameters to maximize performance while minimizing battery drain. Therefore anything out of those parameters (in theory at least) should impact either stability, or battery life. Perhaps the values HTC has decided are not the maximum possible values , because I assume they would have designed the phone to handle few exceptional conditions (i.e: extremely hot weathers). But I think over clocking would probably cause more problems in the long run than whatever the little gains you experience in short term. Just my 2c.

I tried faux 007b5, so overclock free too, I had 1.55ghz indeed, but never for quadcore, just for single or dual. Sadly I wasn't able to reach 1.5ghz quadcore but 1.4

Can you check, with tegrastats, if you reach 1.55ghz quadcore or only for 1,2 (or3??) cores?

So I installed the Perseus kernel and with Stweaks I overclocked the CPU at 1800Mhz.
Antatu = over 19000 points
Then I oced the GPU only to 800Mhz = 18400 Points
But when I decide to overclock both at maximum (1800/800Mhz) I get low score.
Even overclocking the CPU @ 800Mhz and CPU @ 1700Mhz = lower score than just CPU @ 1800Mhz
Is it because the CPU is throttling? What's wrong?
Dear cyber.bg,
Yes probably your cpu is throttling to 800 mhz from 1800 mhz because it reaches the temp of 80c...
To avoid throttling, you have to undervolt cpu when overclocking...
According to me , overclocking gpu over 533 is useless and also makes a lot of heat which push cpu to throttle ... Even gpu @640 mhz with higher voltages you will face freezes and lags...
So just overclock your cpu to 1800 mhz but with lower voltages... Most note 2 cpus can do 1800 mhz @ 1250mV... You can try to give -25 to other values from 1250 mV... 200 mhz @ 775 mv is also fine and no deep sleeps for me.
Dont overclock your gpu but you can undervolt it a little bit... gpu @533 is fine with 1050 mV...
With the right frequency and voltages for both cpu and gpu there will be no throttling so u can get real antutu scores... cpu @1800 and [email protected] with lower voltages, u can expect an antutu score between 19300 and 19800 depending on your rom, kernel and tweaks...
You can use stweaks app to overclock and undervolt...
You can use system tuner pro app to observe cpu temp and other data...
Hope all these helps...
Kind regards.

Thank you for your reply, it was very informative
Currently I am with Note2Core AS (the 1.92Ghz kernel) and I still have the throttling problem, even though my CPU temp doesn't go beyond 50C in Quadrant. But it is till throttling.
I've tried to edit voltage with SetCPU, Voltage Control Extreme and System Tuner Pro, but they don't stick - they just revert back to their original values (1425mV for 1.92Ghz) Stweaks says Sorry, no kernel support.
The interesting part is that in the beginning I managed to run 1-2 benchmarks without Throttling, but anything after that is throttled. Best scores so far:
Antutu: 19868
Quadrant - 7941
Do you know why I can't edit voltages and why it throttles even when CPU temperature is low?
Maybe it has to be plugged in and charging from the Wall?
Dear cyber.bg,
I am using perseus v29.1 kernel and it supports stweaks app... Also i can use voltage control or setcpu with this kernel but i prefer stweak since it has native support in the kernel.
First, 1.9 mhz @1425 mV is really high and thats why your cpu throttles...
I do max 1.8 mhz @ 1250 mV to avoid throttling... I did many test and voltages above 1250-1300 will bring throttling back. My cpu is stable @1250mV...
With quadrant cpu may not throttle because it is an outdated benchmark and i am sure it doesnt use all the cpu cores @100 percent...
Antutu is the solution to observe for throttling...
To observe temps and throttling, run both antutu and sytem tuner pro in split view...
Also i use a 4k video to push all the cpus to max and view video in floating windows so u can see all the data in system tuner pro while video is playing in floating window.
Lastly, my advice is dont go over 1.8 mhz @1250 mV for cpu and 533 mhz @1050mV for gpu... i am sure with these settings, u will have a stable note2 with no throttling and at its max performance...
Hope all these helps...
Kind regards.

Thank you again for this very knowledgeable post
I've used Perseus too. I even switch them daily while experimenting.
I put the Note2Core because I want to push the phone to its limits and get a really high benchmark scores. I've seen people reaching almost 9000 in Quadrant. And for Antutu I already got a really high score (19548), but if I manage to stabilize it at 1920Mhz I can get higher. But it throttles
And I still can't understand why it throttles? Some people say it's because of the high temperature, but how high is high? When I finish with a benchmark and go to look for the temp the highest I've seen is 50C. Is that high?
Also how do I run Antutu and System Tuner Pro in dual view? Their icons are not in the side menu that I open when holding the back button. How do I put them there?
Have you tested with more than 1800Mhz for the CPU? or more than 533Mhz for the GPU only? Can you post some Quadrant and Antutu screenshots so I can compare.
Thank you again
Dear cyber.bg,
Here is my antutu and quadrant results...
Wanamlite v2.1
Perseus v29.1
Cpu 1.8 mhz @1250mV
Gpu 533 mhz @ 1050 mV
Antutu ~19300
Quadrant ~7300
I have run both antutu and quadrant only one time...
By the way, cpu begins throttling when its temp reaches 80c so i am sure you hit this limit...
I have also tried 1920 and 2000 mhz with angelom kernel but because of throttling and so much heat, i had to return back to 1800 mhz with perseus kernel...
Kind regards.

Dear cyber.bg,
1- The only way AFAIK is to use system tuner pro app... Be aware that apps like setcpu reports the BATTERY TEMP not the CPU TEMP...
2- Unfortunately NO since these speeds need min 1400 mV to be stable but throttling occurs immediately so no meaning to overclock...
Steps to observe throttling...
1- Download and install system tuner pro...
2- Download and install super video app and set it for software decoding not hardware decoding.
3- Grap a 4k video (life in the garden) from you tube with the tube mate app... i use this 4k video because it pushes all the cores to max with nearly full load in software decoding mode...
3a- Alternatively you can use antutu and system tuner pro app in split view to observe data... You have to flash this mod in able to add these app to multi windows list... http://forum.xda-developers.com/showthread.php?t=1953705
4- Play 4k video with super video app in a floating window...
5- While video is playing run system tuner pro app and touch to cpu button...
6- Now u should be able to see cpu data like temp,core speeds,load and also video in floating window all together
7- Observe the cpu temp and core speed... if the temp reaches 80c then core speeds down to 800 mhz which mean cpu is throttling... Try to undervolt some more to keep cpu under 80c but with stability of course...
As i said before, the max i can go without throttling is cpu 1800 [email protected] mV and gpu 533 mhz @1050mV... With these settings i can maintain stability, and full benefit from overclocking without throttling...
Hope all these helps...
Kind regards.

Dear cyber.bg,
Nice scores... Well done... Which rom ?
During my observations with system tuner pro, i have realized the throttling temp is 80c..
I think the throttling level can be configured via kernel so this is up to the kernel developers... i remember from note1 that there was thor kernel and with this kernel cpu was throttling @85c and to 1.4 ghz not 800 mhz if i am not wrong...
Kind regards.

Scores were with stock 4.1.1. I haven't installed any modified ROMs so far, cause I like the stock
Btw I'm afraid to use System Tuner Pro now, because last time I tried to uninstall it my phone froze, but I pressed the power button for 5 seconds and restarted. On the 2nd attempt to uninstall it the same thing happened, but after restarting the OS didn't want to load. I didn't have a backup or anything and had to reinstall everything. At least I put 4.1.2, so I'm making a Nandroid backup through CWM recovery now. That was a good lesson.
Have you tried 1.8Ghz @ 1200mV for daily use?
Dear cyber.bg,
Yes, i tried 1.8 @ 1200mV but i got frezees while playing some 2k and 4k videos so i decided to be safe and push it to 1250 mV even 1225 mV seemes stable for my cpu...

Hi PROTOCHIP,
Can you send image files of your's STweaks settings? (for oc and for battery life)
Your experience is so reliable.
Thanks a lot.
Why can't I see any difference between the 533Mhz GPU and 800Mhz GPU on the GLBenchmark? I don't OC the CPU, I even tried to lock it to 1200Mhz to avoid thermal problems however I couldn't reach above 18 FPS in Egypt test. Normally it is 17, with 600 or 700Mhz it goes to 18 and then stays there.
When I compare the GPUs of the SGS3 and Note 2 there is %10 overclock on the Note 2 side and the results exactly indicates this. SGS3 scores 15 FPS, Note 2 scores 17 apprx %10 higher. From this comparison i take it as the results are linear with the clock speeds. I was also proving this theory by OCing the Note 1 to 400 Mhz and reacing a few FPS below SGS3 on GLBenchmark. So, without any problem Note 2 should score 30-31 FPS on 800 Mhz but that is not the case in real life. So I guess it is either never goes to 800 Mhz or thermal throttling happens during the test. Orrrr, maybe 1080p offscreen is not a good option to push-test our Mali-400s? But there is no other GPU benchmarks to push our devices like offscreen because of the 60 FPS lock.
What do you think about this? Is it possible to reach the 30 FPS level?
Can you guys tell if this is ok? Or can I still go lower.. I just eant fair speed with battery saving..
Thanks in advance

Why can't I see any difference between the 533Mhz GPU and 800Mhz GPU on the GLBenchmark? I don't OC the CPU, I even tried to lock it to 1200Mhz to avoid thermal problems however I couldn't reach above 18 FPS in Egypt test. Normally it is 17, with 600 or 700Mhz it goes to 18 and then stays there.
When I compare the GPUs of the SGS3 and Note 2 there is %10 overclock on the Note 2 side and the results exactly indicates this. SGS3 scores 15 FPS, Note 2 scores 17 apprx %10 higher. From this comparison i take it as the results are linear with the clock speeds. I was also proving this theory by OCing the Note 1 to 400 Mhz and reacing a few FPS below SGS3 on GLBenchmark. So, without any problem Note 2 should score 30-31 FPS on 800 Mhz but that is not the case in real life. So I guess it is either never goes to 800 Mhz or thermal throttling happens during the test. Orrrr, maybe 1080p offscreen is not a good option to push-test our Mali-400s? But there is no other GPU benchmarks to push our devices like offscreen because of the 60 FPS lock.
What do you think about this? Is it possible to reach the 30 FPS level?

Dear _delice_doluca_,
Same here and never had the chance to go over 18 fps with my note2 too... Overclocking over 533 doesnt help because of gpu throttling... In theory as you stated , we should go over 30 fps easily but in reality, this seems so far...
Kind Regards...
On behalf of the people who found this thread to discover your great insight and findings Protochip, thank you.
my cpu is running at 1.3ghz 1025mv however my phone reaches 67c true temp and throttles very easily any idea if this normal i cant play any 3d games unless im sitting near a fan or ac. Everyone says they throttle at 80c, i came to this thread from another post i had made. Im mostly playing
Nova 3 and mc4 .

i found that the real throttling problem is a security protocol that Samsung roms have. When the battery reach 41C the cpu throttles (no matter if its only at 60C cpu temp)
i dont know how to deactivate that protocol...but if you want, try CM10.1 or any other AOKP or AOSP roms and you´ll se that there is no cpu throttling unless the cpu reach 80C.
you´ll need "stability test" app (cpu stress testing, and you can watch battery temp), and "system tuner" app (to watch live cpu temp during the stress test)
I am using ElementalX kernel on stock 4.4.4 android. I have to OC set to 1.944GHz currently. AnTuTu bench at 1.944GHz and 450MHz GPU gives me between 24-25k result. Now if I lower the CPU to 1.89GHz it drops to 21k. And if I go back to stock freq I get 19k. Something does not seem right in the test results as related to the frequencies. Question is this: Are there sweet spots in the frequency range for the CPU?
P.S. I know many people dislike benchmarks...I'm using it for comparative purposes...

It states it in the thread, having cpu at 1.9ghz is not economical with battery consumption and performance, it Is best at 1.7ghz

You should monitor your CPU temp and frequency while benching.
You would see that your CPU's temp probably goes above 70°C if not higher and so the kernel thermal throttling policies would downclock your CPU's max freq. in order to keep your CPU "cool".
If you first bench @ 1944MHz then bench @ a litle lower frequency and have very lower score then its not because of the lower freq. but because you did first heat up your CPU @ 1944 and when you re-run @ lower freq. your CPU is already very hot and so does a severe thermal throttling.
Last point : running your CPU @ 1944MHz is not good since thermal throttling while happen every now and then.
Not convinced?
Then simply launch the camera app and try to take a video of 5 mins...your CPU will become so hot that it will downclock to something ridiculously low and your recording will become jerky.
