I installed the webtop over hdmi mod on my Atrix and while testing it out, it got very warm in my hand. I opened the setcpu app and noticed that while overclocked to 1.3GHz, the CPU was running at 75C! I lowered it back down to the stock 1GHz and the temp slowly went down and settled at 63C.
It seems that while in webtop mode, the CPU is taxed at 100% all the time so I'm wondering if it's safe to stay overclocked when using webtop.
Everyone has different opinions of what is too hot around here.
IMO the cooler the better. IMI No Atrix should have a temp above 60c and I'm not even comfortable with above 50c either...

I have experienced the same problem and worried that something may fry.... I have had mine overclocked at 1.45 using debian linux and all of a suddent he phone freezes and restarts.... Since it did it to me the second time I have kept my phone at 1Ghz... I am new at this so please don't beat me up too bad for being a noob... Just want to see if maybe undervolting it a little might help or hurt it?
Thanks in advance
Here are some tips I can offer
1.Try re-flashing your custom kernel and see if that fixes the web-top thing and over heating
Whenever the phone is plugged to the web-top it will naturally overheat so it's kinda expected remember now it's gotta work harder since its displaying on lap-dock or TV,but if you can cook an egg on it it might be too hot...lol
2.Set profile for temperature on setcpu so this way once you reach for example 100F your phone will clock down a little and so it might help the heat issue.You can set even more than one temp profile so this way when it reaches 96 it goes down a little then when it reaches 100 it will clock down a little more and such.
3.If that doesn't help,which in my situation it did.Flash a different kernel mayb it's just the one you're using that is causing funny stuff to happen.
Edit: not sure but i think undervolting helps battery but causes more heat,I myself don't undervolt I just created litterally a bunch of setcpu profiles for battery level,screen off,incall,charging,temp,and time and I'm getting 13 hour days at 1.3Ghz and temp profiles have been helping by clocking down when it's too hot therefore saving battery and drastic overheating.I dontlike my phone going anything over 104F it gets me paranoid,but that's just me.
I tried reflashing the kernel but it didn't change anything. I'm using Faux's 1.3GHz overclock kernel for Gingerbread (2.6.32.9). Is there something else I should be using?

Do what sktrix said in rest of his post.
I use the stopgap 1.0GHz kernel, and UV does lower temperatures. I would definitely try UV'ing a wee bit. You don't need to go crazy. I am using the following with great results for both temp and battery life:
-50
-50
-75
-75
-75
-100
-100
My setcpu profile clocks it back if I reach 60C, (I idle in the low to mid 30's). Under heavy load I reach around 52C max which is quite acceptable.
Now, granted I am not using Webtop, but the end result for UV should be the same. Lower temps and better battery life. You may also want to try just using 1.0GHz when on Webtop. The phone has more than enough power at this clock speed.
There is a bug with faux's kernel that causes the webtop to clock the phone at max speeds until restart.
Sent from my MB860 using xda premium
I know I'm straying from my correct forums here, however I have an LG Optimus 2X which like the Atrix, is a Tegra 2 CPU.
Our phones get VERY hot, I have had my CPU up to 86C before I decided to back off the stress test. CPUs are very good at handling high temperatures, and IMO you will see no ill effects from doing so, I am unsure of whether or not the Tegra 2 has thermal throttling/shut down, but in my experience they should be fine to around 80C.
The only issue I can forsee is the battery, batteries HATE high temperatures and it is awful for their life span, this is why your laptop batteries turn to crap after 1-2 years, even if low charge cycles, because they are always hot.
I would not be concerned about anything in the 70C realm, at all.

Experienced this countless times. More with the latest 1.45Ghz, but it did happen on the previous release. When I dopped the mhz with setcpu, it wont scale but stay at max cpu. It even did it a few times without using the webtop.

So which overclocked kernel is best for webtop? I too have noticed where the CPU hangs at 100% at 1.45Ghz for a while when disconnected but it is always there when im in webtop mode.... How is Faux 1.3Ghz kernel with webtop?

It will still hang at 1.3ghz, though it's a known bug. I just stick with the 1.0 enhanced, there's no noticeable real-world difference from going over 1.0ghz anyway, it's just a benchmark gimmick. Right now, the software that's out there is optimized to run on existing hardware w/o overclocks. I've run Shadowgun at 1.45ghz and didn't see any difference over the 1.0 enhanced.
Now, if we were trying to run games that were coded specifically or faster-paced chipsets then we'd need overclocking to catch up much like you would in the PC arena. That, however, is not happening in the cell phone market just yet.

You will see a lot more optimization than just upping the clock speed. One of the reasons the 1.0GHz kernel works much better than the stock kernel. Also, the ability to undervolt saving battery life.
IMO there is no need for 1.3GHz or 1.45GHz in everyday use of a phone. The only benefit is for OC'ing bragging rights. Until we can control phone temperatures better, it's pointless to risk the substantial heat increase on ALL internal components for extended periods of time which results from much increased CPU temperatures.

I see... guess that explains why the phone doesn't really feel any faster when it's overclocked. I'll flash the 1GHz kernel then.
Thanks for the info.
Not sure if this is the same with phones but normally a CPU should stay at 40C idle and 50C load. Maximum would be 60C while benching or something.
If it goes above that I would definitely underclock/undervolt.

Samsung Fascinate CDMA
Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Neh4pres,
Yeah, I kind of feel like a heel. For some reason, I had a brain fart when looking in the 'General' section of Voltage Control. I see now how to overclock.
Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.
mkropf,
I see that now, and thought as such earlier, but needed some clarification.
Having so many issues with Glitch and 1.9.9, I'm hesitant to install Glitch, but interested to see if it runs better on the newer MIUI...

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.

OP even if you crank it up to 1.6GHz, unless your isolating that step, your phones not using that clock speed unless your doing sh*t on your phone.

The benefits of overclocking you ask? Let me tell you just a few.
1. For every overclocked phone, one dollar is anonymously donated to poor and starving children, families, and college students across the world [citation needed].
2. Overclocking your phone emits a low frequency gamma wave inhibitor which in some cases, tested by prestigious scientists, has proven to protect you from harmful UV rays from the sun, nuclear fallout, increases neural synapse action in the brain, lowers bad cholesterol AND blood pressure, increases lifespan up to a minimum of three years, and is a natural antimicrobial agent that also interacts with your white blood cells to not only increase output and strength, but also breaks down the DNA rebuilding process by inhibiting protein synthesis in a wide variety of foreign microbes in your body.
3. Overclocking has been used to successfully treat sever depression, obesity, dementia, and AIDS.
4. With an overclocked phone, it's been observed waiting times for and inside elevators is severely decreased.
5. Bad driver? Accident prone? Overclocking has been shown to heighten driver awareness and overall skill.
6. It speeds up your phone on a day to day basis, with some, but not terribly noticeable battery drain [citation needed].
Sent from my SAMSUNG-SGH-I777 using xda premium
Overclocking is entertaining. But I'm running the Unnamed rom on my device and have it UNDER clocked to 800mhz. Crazy good battery life and zero lag.
Overclocking is pointless as it runs everything great already. I'm waiting to overclock until my phone is outdated and my contracts about to expire.
While its rather easy to do there really isn't any benefit to overclocking the SGSII. Yes, it'll run a little faster and your Angry Birds might run smoother (really? ), but it'll also mean a little more heat and more battery drain all to accomplish something you really won't be able to get any real advantage from.

On the other hand, if it was a snapdragon processor, you'd need 1.5 GHz just to be marketable next to this phone (and 1.8GHz to perform as well in day to day usage.)

Most people overclock for a smoother/snappier experience. I notice that roughly 20% increase in scrolling/tabbing around. Also you can think of it like this:
1.4ghz will finish tasks faster then 1.2, that way taking less battery. You could also undervolt that 1.4 to 1.2 (1275mV), so your finishing tasks quicker while draining no more then stock.
I switch between 1.4 and 1.0 every other day it seems. 2 months later, still looking for the right one for me. 1.6 should only be for benchmarking imo, epeen.

It's not that simple.
There are dozens of bottlenecks in these devices (and any other computer), and 9 times out of 10, it's NOT the processor. Persistant storage, RAM, bus speeds, etc - all those things will ensure that a 10% bump in processor speed will NOT give you a 10% decrease in run time for a given typical application. In many cases, you'll see no speed increase at all, as it takes the same amount of time to flush to persistant storage no matter how fast the write cache fills.
I'm not suggesting that a person shouldn't O/C, but don't be surprised when going from 1200MHz to 1400MHz makes no visible difference other than the battery draining slightly quicker.
I know someone is going to respond that the processor will bump back down to a slower speed and therefore it runs at the higher speed for less time, etc. However, unless you have the governor set to poll for usage so often that the governer is driving your clocks up to max, it's not going to poll often enough to make much (if any) difference.
Think of it this way: We both own a mustang, but mine is a V6 at 220HP and yours is a V8 at 300HP. In theory, yours can accel faster and maintain a higher top speed. In reality, neither one of us can go faster than the car in front of us (but you'll burn more gas doing it.) (Of course, you'll have more fun in yours.)
I hope this helps with a very common misconception.
Take care

Very true. Also I am guessing in gaming, that OC will drain your battery quite well.
Consider I mostly do Web browsing on my phone (I need a tablet), 1.4 is a much better browser experience imo. Worth the 100mV.

I run it at 1400MHZ Though with the gpu forced at 267mhz.
ive tried every rom/kernal combination and with each i get lock ups when doing intensive cpu work such as a game or benchmark overclocked to 1.6 any ideas? Thanks
Just means your processor was built a little weak. Its only built to run at 1.2ghz so anything above that is pushing it hard... some phones can be oc'd that much, some can't. Just take it down to 1.4. I can't even get mine to 1.4 so he thankful

What voltage do you have it at? Try raising it 25mV at a time stressing you cpu at each step until you're stable. That is if you are determined to run 1.6 and i would not push more than +100mV personally.

Have you considered there is a reason that your phone was only sold as capable of 1.2 GHz?

Wow... You got real issues man..The OP is just looking for some tips from others that have succeeded in getting their phones to 1.6.. You need some help buddy...
If youve nothing nice to say..
But then I guess youd never speak would you?

I do not think entropy is the one who has issues...
This has been discussed in 10 different threads already and in great detail. If the OP did as much as search he would of have found the answer himself. That is why they call it research
the only question left is...... You mad bro?
Keep all voltages stock, then use voltage congrol and click on 1400 and increment the slider+ 25, then do the same for 1600. This is what i had to do to get my phone stable at 1.6 Some phones may need EXTRA voltage and others need less. It takes some testing to get your particular phone stable at anything over 1.2Ghz. I only did it to see if I saw any gains. Actually for me and my phone I found as far as MY SETUP and testing many different benchmark style apps at 1.4Ghz i got better benchmarks than i did at 1.6Ghz. Now everyones phones will act sligbtly different so your mileage may vary.

At 1.6 ghz... your phone will be discharging your battery ON your charger... I personally wouldn't recommend doing it as it gets the phone really hot, and causes the chip lots of stress due to high heat. Personally if you need more performance (this phones pretty damn fast anyways) go to 1.4ghz.
Most of our phones can be overclocked to 1.4 and some can go to 1.6 but not all. If you change the voltages and it still craps out, then take it down a notch to 1.4 and see how that works for you.

Now now. Since when do we encourage keeping things stock.
My point is - if it were guaranteed to hit 1.6, it would be sold as 1.6.
Being able to hit 1.6 is luck of the draw, pure and simple.
There's a reason:
1) OC is not default on my kernel
2) I held off on providing OC support for a while here, and NEVER released it on Infuse (users weren't mature enough to handle it over there)
3) I have a warning in GIANT RED LETTERS not to complain about OC stability issues on my kernel thread.

This is all true... but the OP was simply asking a question now lets all play nice.
We should have an OC that allows n00bs to melt their cpu.... 2.5ghz ftw
No no no.... We have too many "I tried to load the ICS in the I9100 forums, and I bricked my phone, please help!" threads. we don't need "I OC'ed my phone to 8ghz and melted my cpu" threads too
Tegrak allows you to go past 1.6. I thought these CPU were locked @ 1.6 but i had to up my voltage at 1.7 and i got a small bump in my benches though i probably did run my test enough to confirm the bump. At so.e point, when i get some time ill beat on my CPU some more

I ran my phone at 1.6 for days just to see performance. No UV at all.. battery certainly drained faster, but not while charging. It charged just fine.. and stayed cool even when stressing. Like many have stated, all CPU's are slightly different .. just cause yours melts at 1.6 and wont charge doesn't mean this will happen for anyone trying to run 1.6GHz.
sent from my SGSII... suckas
Try bumpin' up the voltage 1-2 notches.
Just to add to the stats...
I've been able to run @ 1.4 with the same voltage as 1.2, but my phone will freeze once in a while when running apps like camera or navigation. Had to bump the voltage up slightly to get it stable, though I will likely just run 1.2.
I cannot run at 1.6.

Try changing or updating your kernel. Im the OP and had the same problems. with the new siyah kernel at 1.6 even if i try i cant make it lock up or freeze.
Your processor was made from a different silicon wafer than other people's phones and was rated for 1.2ghz.
Since each wafer is different, some processors take voltage better than others as well as speed. It happens.

Opinions from people who really know? I can't imagine that overclocking increases battery life.
It doesn't. At least from my understanding. In fact as I understand it running at higher clock speeds would decrease your battery life no? I usually under clock, so...

The theory is that overclocking allows you to complete processes quicker, which in turn allows the processor to go back to a idle/deep sleep faster. In practice it doesn't really work that way though.

doesn't the increase in voltage also come into effect?
They did talk a little about undervolting to increase battery life. Personally I don't worry about it. I'm not using my phone to sort out heavy algorithims at the moment, so running how it does is fast enough for what I use it at. Just found the article interesting.

They say the undervolting on lower clocks should balance out the higher voltage on overclocks.

Undervolting rarely makes a difference on mobile SoC's, but on the desktop/laptop CPUs you can really save a ton of power with undervolting and underclocking.
Why to overclock and understand it?
Here is a good reason to know what you are doing..
and the battery avg's lasting at least through the day, but most of the time, I have a charger near me...

The article says its not the actual overclocking that is saving battery life. When you put SetCPU on your phone not only can you overlock but you can underclock and set different voltages. I'm not 100% sure how the voltages play into it but you can set the processor to run at really low speeds during certain acts ei. when the screen is off, or any other time you don't necessarily need alot of power. That's and I changed all the voltages (I got them from a post where the guy knew what he was doing and tested them). I get almost 2 days moderate browsing, apps and text. If I talk alot or use my hotspot I only get 1.5 days. It is a little time consuming to get everything just right but when you do you really see it.

This isn't a SetCpu feature there are other programs that can do this as well. It just so happens SetCpu has it built into the program. I bought SetCpu back in my Atrix days and loved it so it does work great for a simple tuning program.

Many of the kernels these days have their own tweaks and mod apps as well

I'm running a kernerl and a custom ROM that allows me to underclock and overclock.
I tried it out both ways and the battery lasted for almost the same amount as on the stock option. As I tend to play games a lot on my phone, the underclocking ran into some issues with stuttering and sometimes force close of a couple of games.
Personally, I've never been a big fan of either .
now hat we're unlocked lets overclock and undervolt and see if we can get 10k quadrant and a week out of the battery..lol
no but seriously how much do you guys think we can turn this thing up (overclock) and it be stable? (like its really needed..i cant get it to lag now as it is) once we get a kernel that is

1800 is a VERY good starting point.... I ran a kernel when I had the International variant and it was FAST!! I think it was called "Bullet" kernel...?

I was looking stuff up on that today. The highest I could find documented was 1900 on the cpu and 800 on the gpu.
For everyday usage, overclocking is useless, even for gaming. Undervolting can be beneficial, but from what I've seen, the latest processors get approximately the same battery life on stock voltage as they do undervolted.

hey thats good to know...like i stated though. if there ever was a phone that needed over clock this one IS NOT it. i cant bog it down right now and believe me ive tried. someone out there might can but i cant.

I just like to play around with different kernels but the kernel I was using def made the device snappier and I had some killer benchmarks! But you are right though! Custom kernels on this device is not really necessary...
I plan on building a custom kernel then, hopefully tomorrow night or possibly Saturday. I do have some plans to improve it, but nothing related to the CPU or GPU going faster, just having other stuff operate better and getting rid of anything not needed.

I hope I don't get another lemon CPU... my TBolt's would only overclock to 1.4G, anything above and it locked up.

That's better than me. I could run 1200 for weeks but at 1400 about every other day it would restart randomly.

HA. My TBolt stayed stable at 1200, but ANYTHING higher than that and it would crap out on me.
I could run my bolt stable at 1700 all day. Kept it at 14 for a month no issues. Stayed at 13 the rest of the time. Course at 17 it was like it was running on a watch battery with the amount of time it would last. Lol
Eh I ran 1.6Ghz on my Thunderbolt 24/7 and with the 2750mah battery it lasted me days.
On a phone like that there was a significant improvement to the end user that justified the overclock. Now on the Note 2 I'd expect there to be very few who would want an overclock at all. I am part of the very few however. I play a lot of emulators on my phone and for N64 and Playstation I need all the raw CPU power I can get. Yep, even on this beast of a phone I still get some lag and stuttering on those emulators. The reason being is the same as PC gaming. AMD thinks that by adding more and more cores to their processors they can win the performance arena. Unfortunately they are wrong. Intel has the right idea, 4 cores is plenty now let's improve the efficiency and performance of those specific cores.
Same goes for our phones. Quad core is the most I'd ever want in my computers, anymore is just a waste. Now let's get better architecture for the processor to maximize clock-for-clock performance. And overclocking those cores helps it in apps that don't support more than one or two cores, because the baseline performance for each core is boosted.
So yeah, can't wait for a 1.8Ghz kernel
