Hi guys. I looking forward to ROM with can work at 1.2GHz. I think most of XDA users have modified ROM working at 1.2GHz, so everything fine? It's save to run Galxy Tab at 1.2GHz?
1.2 has been stable for me for well over a month now. I run 1.4 from time to time when I want to play games or just show off. Some tabs report overheating, but use setCPU profiles to alert you if that happens and you wont run into any problems. I have setCPU to warn me at 40 degrees and at 41 it goes down to 800mhz. Just keep your eyes on the temperature to be safe.
Its a popular misconception that the tab runs at overclock frequency ALL THE time. Unless the kernel (which I seriously doubt coz that would be stupid) is programmed to run at maximum clock frequency or you have set it up yourself (with setCPU or voltage control or w/e overclocking utility you use) which is basically an explosion waiting to happen (or at least crash). The tab runs at a RANGE of frequencies it runs at max frequency (1.2 or 1.4) on demand like playing a game or an HD movie or anything stressful.

You want to say, like PC CPU, that Tab ARM Cortex A8 chip working on range of frequencies? It's possible because of battery save, but I think Tab's Cortex A8 is designed to work at 1GHz all the time without any problems.

DarkPal is right.
While you're theoretically correct too, in the sense that the Tab's Hummingbird is designed to be able to work at 1Ghz all the time, by why would you want to do that? It'll kill your battery if you set it to run at 1Ghz all the time, much less at the higher frequencies that these CPU were not rated to run. Not to mention the heat issues.
There's a reason these ARM-based chips scale up and down the frequency scale according to the CPU governors' settings and load demand, and that's why ARM-based chips are known for their battery savings.

I've been running mine at 1.4 for about a month now but undervolted too. Perfectly stable. If you are using SetCPU app you'll be able to see how much time your tab spends at each level.

Bit of a noob question but apart from games in what other areas does overclocking help?
I notice the difference with video. Crisper and smoother. It's not a big thing, but why not do it if you can?

Because it does run your battery faster and hotter, as well as the processor itself...
Force a sprinter to run 5 miles, they can do it, but I bet they tear something along the way...
Oh yeah, thanks to the illustrious Rotohammer that's not a problem...
Ever since I upgraded to Roto's JMI ROM and a few other tweaks [ see my post: http://forum.xda-developers.com/showthread.php?p=12786456*** Galaxy Tab Master Tweak Thread*** ] the battery life on the galaxy tab has been absolutely insane. Even though the phone is overclocked to 1.4 Mhz.
I used to come home at the end of the day (before overclocking) and my battery would be approximately 15 percent, now it's always over 50 percent. I don't know what the black magic is, but it is good...

So i have been able to clock my captivate to a stable 1300 using suckerpunch #57. I'm wondering though how often do you think are phones actually use this frequency? i know when i'm running a psx emulator im sure that it probably has the cpu maxed out, which runs tekken 3 beautifully now at no lower then 48 fps, but i hope on not much else (would be nice to find an app that would put the cpu used clock speed on taskbar). Only reason i wonder is because of course phones don't have cooling systems like computers so i worry about cpu life.

i have never seen the cpu get hot in my phone. it gets unstable before any heat is detected, but my phone is not very overclockable, i can get 1.3 with much care to the uv settings. i wouldnt worry about heat until the 1.4 mark, even then you are probably fine. the newer qualcom chips have been set to run at 1.9ghz and dont burn up they are on the same size architecture as ours. these arm chips run at such low voltages that heat is not really a big problem. i dont think anyone on the board has killed a hummingbird from overclocking it.
I think your speaking pre-emptively about not burning up.
Just because the chip doesn't instantly melt doesn't mean your not risking electro migration.

this chip has a built in fail safe and can run as long as it can handle it automatically freezes or reboot your phone above its capable limit. If you want real time monitoring of your cpu clock speed/usage, ram usage and battery temp download Temp+CPU V2 widget from the market pretty good app. enjoy
so, i am using the Fear Rom and with the OC karnel. i played around the max sittings to 1.4 and tried quadarant. amazing score of 4150. nice... but what will happen if i keep it at 1.4 ?
will it over heat the phone / burn the GPU/CPU when playing games for example ?
i understand the battery life will be shorter. but what other disdvantages ?

You could dmg ur cpu. But Tegra is known to run 1.8Ghz stable. So with 1.4 you should be good.
Sent from my LG-P990 using XDA App
Oh!! Great 1.8Ghz but only 1.4Ghz is very drain my battery to much.
In the long run, your cpu might get affected but its shouldn't happen so soon.
That said, in my honest opinion, don't need to OC the chip.
The same OCing rules apply from the PC World. The same batch of chips have varying maximum OCing capabilities and thus different stabilities. Although you can stably run a chip at a higher clock, it will definitely shorten its life (Sometimes it could kill it in a year, sometimes beyond what we can measure.). Chip makers purposefully OC chips during tests to simulate the stress effects of using the chip over a long period of time (OCing that makes it seem like the chip is being used for months or years.). Nvidia sticks the Tegra at 1 GHz half because it's cheaper to do so (don't need to ensure higher clock rates which would mean a larger percentage of their chips won't last doing it.) and half because of marketing (At the time, no one has 1.2 GHz like we do now. From what I've seen, Tegra 2 can do 1.2 GHz easy.).
So what it comes down to is how long you plan on keeping the phone and how lucky you are. =)
Imo, in the interest of power savings (P = (V^2)/R), the gains of OCing having an exponentially worse effect on battery life.
imho theres currently no point in oc'ing the Tegra2 in Optimus at all.
Theres no real life benefit, only theoretical benefit when running benchmark apps for show off.
Theres not a single application or game out there today that require more processing power than what the Tegra delivers at 1ghz - and not a single one out there that will run any better or faster by oc'ing because the demand for processing power to run the application or game at its maximum capacity are allready met at 1ghz
Basically there are only negatives in terms of decreased battery and cpu life for nothing but a screenshot of a higher quadrant (or whatever) score
If at some time in the future you should run into a game that would not run smoothly unless the cpu are oc'ed then it would make sence to do so - but for now not.
The games available today either do run perfectly smooth at 1ghz or if they dont, then they dont because of poor programming or other factors and they would still run poorly even if the cpu are oc'ed
Actually there are real life benefits until you find a game which really lags when you run it. Meaning, you should leave it as it is until next year.
It may damage the CPU like what others say but since lower clocks are undervolt it might last as long as a non OC (Stock).
But it will kill the battery faster as you will have to charge more often due to the higher power draws.
Soon, I am getting a Wi-Fi only Streak 7. I have read on several sites that, despite having a Tegra 2, the CPU is clocked to 800mhz per core, to save battery life, rather than 1ghz.
I recall having an old Palm that came underclocked, and hearing that it used the "throwaway" CPUs. When a batch of CPU cores was not able to perform during the QA testing, they would sell it to Palm, who underclocked it. Basically, overclocking to the max clock rate of the processor would be more than it was intended to handle, similar to overclocking a Tegra 2 higher than the rated 1ghz.
Before I set 1ghz as my constant clock rate, I would like to make sure that the CPU is a good Tegra 2, and not a "throwaway" that was underclocked to prevent damage.
Basically, my question is, can the processor on the Streak 7 safely run as fast as another device running the Tegra 2 processor, or are these the processors that didn't make it into another device because they failed QA testing? I plan on setting 1ghz for most uses, but overclocking to 1.2 or so for emulators and certain games.
Thank you
bump. Same question here. I have the wifi version also and it has been getting a little laggy.
Well me personally, I have been running at 1Ghz for several weeks. Seems fine, gets warm when I play specific games. But for random work and internet usage it runs great.
Thats a myth. Cpu is 1ghz for both cores.. You can downclock if u wish though I doubt its gonna make.much diff to battery

I ran it at 800MHz for a bit to see if it would help conserve battery. It didn't, but it also didn't negatively affect performance. The Tegra2 is really a great SoC.

So, the Streak 7 is NOT underclocked from the factory?
And on a related note, I've heard some programs allow you to overclock and underclock without a custom kernel. Which of these, if any, work on the Streak 7? I can undo rooting it, but I'd rather not flash over it with a custom kernel, in case I need to send it in for repair.'
EDIT: If you search for "Dell Streak 7 800mhz", you find a few reviews stating that Dell underclocked it. Figured I should show the link, so people don't think I'm crazy. I've also found an article saying that it auto-downclocks, running 1ghz as needed, 800mhz when not neeed. That seems to make more sense.
It absolutely is not underclocked by default tho by the design of the core it does not run at full tilt all the time and drops back to 216mhz when idle -goolge cpufreq for info bout that

Never happened to me. I was always under the impression that, unless you are using a custom config file, it'll just use the settings that your kernel lets you use.

The stability is dependant on your hardware; some chips can only overclock to 1500Mhz and some can overclock all the way to 1900Mhz. It is not something the kernel has a say over.
Don't all of the notes have the same cpu? Why can some be overclocked and others not?

They all can be overclocked, but how much is a different thing altogether. It's quite simple really, not every chip manufactured is of equal quality; some chips have more imperfections. The more imperfections the less it can be overclocked before it becomes unstable. It's the same thing as on PCs, too.
Stable is it when you do nothing and use it in originally form. Overcklocking need more Power more power is less time you enjoj your note!
Generally these chips are made to tolerate a certain speed, and because of variability, the manufacturer drops the speed tolerance to ensure overall quality. Some will still be able to manage 1500, 1700, or even 1900 (although rarely, I'd say). Just about all of them tolerate 1400, so very few are defective at the stated tolerance. With 5 million, you will get a few, however.
This is one of those rare occasions when statistics have a benefit in the real world!

There are many out there that will let you overclock. Search the Android development forum.
Like most, I have flashed heaps of times, probably at least four or five times a week when I first got this wonderful Note, but in the last month or so have only been tempted to stray three or four times. Personally Franco 6 is best for me, because I favour battery life and stability rather than overclocking (1400MHz is not bad as a standard!!)
I would encourage you to try a few for a few days, as long as you backup often you should have a great experience!
Are all kernels capable of overclocking?
Is there one that overclocks the best?
How do you tell how high you can go?
Do you jusy keep overclocking until the NOte stops working?
If so, there must be a fine line.

Stock kernel isn't capable of overclocking.
One way to tell is to download things like SetCPU which detects the range of the clockspeed. Another way is to simply read the description of the kernel thread.
How high your phone can go is an individual thing. You need to overclock in slight increments (say 50mhz at a time) and run a stability test to see if the phone crashes or not.
You DO NOT pull the slider all the way to 1.9 ghz and "see" if anything happens. If you fry your CPU, do not come to us for help.
This is why I don't like overclocking, it's a waste of time to run the stability tests, etc.
In summary, you need to raise it a little bit, and run stability tests and repeat the process until your phone crashes. At that point, you'd know the last safe-stable clockspeed that your CPU can take.

What do you recommend for a good stability test?
I'm on franco.kernel v10 and OC to 1600 using Tegrak. Tegrak runs the stability tests automatically and reverts to stock 1400 if unstable or a reboot occurs.
I tried 1700 but Note rebooted after about 2 minutes. Booted right back up at 1400 with no problems. Re-set to 1600 and running smoothly.

Both seem to have the S3 APQ8060 CPU, which is 1.2-1.5ghz. Does this mean the touchpad is technically overclocked..ie..100% safe to OC to 1.5?

To save battery life mostly, Apple underclocks the iPhone processor IIRC for the same reason.
Also while manufacturing chips for same speed, not every chip will achieve the same clocking...keeping everything same one chip can go to 1.9 while other can just go 1.5...so most manufacturer sets at stable frequency..so that every chip can achieve that
Almost all devices are under clocked in some way.
just make sure you use a cpu tuning app like setcpu or whatever to tune your frequencies
Most Touchpads can easily do 1.5 since that's the rated speed of the chip.
1.7 or higher is not within specifications and not all TP's can do it. I have one that runs 1.7 right now without issue, but the last two I had refused to go above 1.5.
The reason has something to do with the nature of the cpu making process. Just to let you know, there are some variants of desktop cpu even though they have same architecture, take i7 for example, why do you think one sells more expensive than the other? The reason being the most expensive one (9 series) has least defect in the cpu, enable it to utilize the most transistors and this is pretty rare, therefore they priced higher.
All cpu were made in the same process, the one that have more defects will priced lower, they in fact shut down the defective part and mark them 'more energy efficient' while they are effectively running less transistor.
The same thing happened here, not all cpu is perfect, so not all cpu can be clocked high. So they decided to take 1.2ghz, as it is probably where most manufactured cpu able to cope with. i.e. if you device can run 2ghz or more that mean you get the almost perfect cpu, as simple as that.
My Touchpad overclocked in WebOS @ 1.7 but can't get higher without it crashing. In Android however, using Bricked Kernel on CM Official Nightlies I can reach 2.02 Ghz (not stable without vcore changes but could be stable, just keep in mind of how warm the Touchpad's getting) and 2.157 Ghz (with unsafe voltages for benchmark suicide runs).
