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

Hey guys, I just lost my ability to adjust my setcpu over 516mhz. This happen to anyone else?
Says something along the lines like it cant find my setcpu config.

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.

I just overclocked my droid using the tazkern 1.1 Besides being miserably slower than before when I boot up, It doesn't even give me the option to go up to 1.1 ghz. Any suggestions?
suggestion:
and don't take this wrongly in any way..
Stop overclocking so much!! It's a damn phone, not a gaming rig. That and also you really risk of damaging of your CPU and other internals...
My Milestone is running stock. It stays cool and is fast enough. This is after i tried some weeks running it on 800 Mhz. It gets too hot and that also during conversations.
I get where you're coming from but still, I was just getting a lil tired of the the thing lagging every time i opened the app drawer or market. I actually fiddled with it a little after I posted that and got it to run perfectly. And I think Im fixing to try out a 1.2ghz kernel just to see what happens. So far there's been no overheating or crashing.
ECC is kicking in and making your phone slower. Use a lower clock, your phone doesn't support it.
Actually its running quite smoothly so far. Ive been running it for around 30 mins now and its super fats, smooth, and appears stable. Ive tested it on youtube tho and its getting pretty warm.
Mines runs all day, every day at 1.2ghz. The quirks are not from the overclock. Thbey were always there.
Thats what Im on now. I think Im using the slayher 1.2ghz kernel.
Droid or Milestone?
If Droid, you're in the wrong forum. This is the Milestone one.
I have mine at 720mhz overclocked and it works fine,i dont have any heat problems,i always check the battery tempeture via SETCPU app,always is at 30C to 32C,not more than 32C!!!
I love it more tha my iphone
I think people need to learn the risks of overclocking.
You may say its stable and running fine and "just a little warm" but you are infact destroying your CPU.
If you touched your computer case and "it was a little warm" you would be worried.
Consistently hot systems aren't expected to last anywhere near as long a cooler systems. Thermal fatigue in silicon results in cracks in transistors, and transistor mounting failures, in particular. Of course, just one transistor failure on a complex system such as a motherboard or graphics card can result in the entire system failing. And a replacement board being an appropriate fix.

Oh dont worry. I turn my phone by the time it burstsinto flames. And btw i apologize but i did post this in the wrong forum. Oops.
droid doesnt equal milestone. development is different due to locked kernel / bootloader..
but saying that. i use 1.2ghz with 70 vsel, or 1ghz with 60 vsel.
its a little lower voltage, but i assume it saves battery.
might not be stable for you, but i've been running it for 8 days straight now..
i dont use a lower voltage cuz i heard it damages the cpu. i stay within safe tested voltages

milestone users have to rely on a kernel module to overclock.

overclocking damaging the phone? please.. the omap 3430 has the same CPU as the 3630
3630 is upclocked to 1.2ghz and is in the droid 2. i suggest you checking out T.I.'s website. our cpu is clearly capable of reaching these speeds without damage.
Besides. i've had my milestone ever since it came out. I've been overclocking it since it became an option and my phone has never died.
but saying all that. an inexperienced user playing with voltages can seriously damage their phones if they dont know what they're doing. too high or low of voltage or speed can result in a brick.

The OMAP 3430 is a 65nm chip while the 3630 is a 45nm chip. Newer smaller manufacturing processes = cooler chips. They are NOT the same chips by far.
Furthermore, you realize that many memory chips are made equally. Then the memory manufacturers go and test out different batches. The ones that clock higher can be stamped as higher clocking or faster timing memory. They may be made the same, but usually the better made batches go to the higher end parts. The same goes when Intel makes CPUs. The crappy CPUs with some problems become Celerons. It might've been a Core 2 Duo or i7 or whatever, but Intel goes and disables cores/cuts off memory if it was not a good batch.
You can't look at models and go "well that CPU can do it, why can't mine."
If people have knowledge of CPU overclocking here where you understand that people look for certain serials/batches of Core i7s for best overclockability. Even though to Intel they all meet i7 930 specifications, there's still separation within the i7 930 crowd. Certain batches are better. Maybe not good enough to be an i7 950, but still better than the worst i7 930.
The other question is: What is stability? How do YOU determine what is stable? apps not crashing? In the overclocking world we run Linpack tests for like 24 hours before calling computers stable. Just because you can boot into Windows or Android or play Angry Birds for 3 hours doesn't mean much. It doesn't mean you don't suffer from bugs from overclocking. It's hard to say unless you do a full stress test on your CPU.
The 3600 OMAP is clearly superior to the 3400 series, but I do think that the latter is more overclockable.
I've had no overheating issues at 900MHz, 56 vsel, don't feel the need for higher frequency.
Will, this is all starting to go over my head. I'll just sit in the corner n twiddle my thumbs.
Just think of the 3600 as a 2010 Intel i7 chip and the 3400 as last year's i7 CPU...same platform and architecture but smaller manufacturing process and (probably) a bit faster at the same clock speeds, with the same features.

I was just trying to get at the same idea
I might have been too exact in my words but this is what i meant
and something fyi is that the OC capability of both chips are "capped" at 1.2ghz ... its just dangerous and unstable after that.
heat wise ? I'm inclined to believe that heavy wifi / 3g usage provides a higher source of heat than our petty oc-ing. Our cpus are clearly capable of this. true you make a good point. smaller architecture = cooler and less power. but the heat is probably out of the question. i use setcpu to display my temp. it never goes past the rated temperature. in fact it always stays at around 35c
when using wifi/3g on the other hand.. no need to say. the fact that these chips have no thermal barrier between them and the fact that the heat is able to be felt on the surface on your phone... in such close proximity to the radio chips, the cpu is not going to be heated by oc but by these other factors.
its safe to say you should lower your 3g / wifi usage to reduce thermal stress on your phone
stability wise... I'm not the one to stress test or w.e for long periods of time, but the link i've attached to my previous post shows a lot of people who have.
maybe you should check that out. I'm just here to relay information.
I have mine overclocked to 800 and it stable and quicker than stock its not all cpu its the amount of free memory you have at any given time
here is another very interesting page. this time regarding the droid
http://www.droidforums.net/forum/droid-hacks/20406-max-temp-while-overclocking-12.html
be aware that a lot of the temperatures are in fahrenheit.
highest temps of these guys average around 40-50 Celsius, way below the rated temp
Actually, mine has been running smooth this past week or so with no abnormal heat or crashes.

I'm not sure if the app just doesnt know how to read the cpu speed on the streak 7 but I installed CPU gauge on my streak 7 (with DJ Steves perf mods) and it's only showing my cpu speed as 598Mhz.. Is this right or is the app just reading it wrong since it's a T2? something doesnt seem right.. either the app is wrong or this baby is severely underclocked

What it is reading from, is probably /proc/cpuinfo
In that file, the BogoMIPS = 598
BogoMIPS is a kind of way of measuring CPU speed, but it is very different from what we normally understand as how fast it is.
So the best way to measure, is to assign some task (which utilize CPU intensively) and record to time. Do several times and get average messure.
Current market place there is no (to my best knowledge) apps that can correctly measure this Tegra 2 Dual Core yet.
Please let me know if anyone here found one that ACTUALLY measures correctly.
Many claims so, but what they are doing is just cat /proc/cpuinfo, which is incorrect/inaccurate.
Cheers,
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
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.

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...

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).
