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.

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.

Read the history at the following:

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.

also has other fixes besides overclocking you can go read them in the kernel threads
hey guys i install custom karnel on my xpera mini...now i can overclock up to 2 ghz..i just wanted to know pros and cons of overclocking..
pros- increased speed and less lagging,
cons- short battery time, increased temprature.
Is it possible to underclock it to get more battery or shelf life from the phone?
we can overclock and underclock if we install custom karnel..

Yeah. Root your phone, and install SetCpu, and you can Underclock freely and thus save lots of battery

Overclock will give you temporary boosts and lets you to showoff, and to get super high benchmark scores , but its not for regular use
Overclocking reduces battery performance and increases heating of device, which might cause your device to get unstable
and of course high temp = bad for the hardware so be careful
My SE mini works very well at 1610 Mhz.No crash,no instability but I use high frequency for max 2-3 hours or when I want to play without lagging
Pros
Immensely fast speed
Massive score on Quadrant
No lag or crashes
Cons
Battery life goes down fast
Phone temp goes up - Massive problem
Phone might get bricked if the phone gets unstable (Happened to my friend)
I only overclock my phone whenever I play games or need to switch between apps constantly. Though I always keep on 1024 as that is the default setting
Recently I overclocked to 2ghz was chkin stability and gosh I burned my battery, its workin but fone keeps restarting n I had to buy new one!! Dis is d con
Pro: faster n better performance!!
Overclock can cuz serious damage too!! But its fine to showoff a lil but in controlled envionment for a short tym!

Overclocking is not actually advisable because there are chances that it will affect your phone and might screw it up in the long run .
Battery drain is inevitable and you will experience it .
Phone will heat up
It may not be good for the other internal components because of the over heat-unlike computers a mobile is not actually equipped with much of cooling system.
There is a good reason why the manufacturer has set a clock speed ,otherwise isn't it better for them to just overclock a phone and sell it for a higher price ?
People who design the custom kernels are just telling the maximum possible value they could overclock to.
Pros-
Bigger numbers
Little more faster performance
it recommended to not overclock always..just overclock when you really need it..
What are peoples thoughts on a modest overclock to bring me back up to the performance I am used to?
Say taking an ACTIVE up to 1300 or so.
With these new NON-OC kernels, are they undervolted? I have seen claims of absolutely massive battery life and I'm reasonably sure some of those were using cpu throttling and an overclock.
So confused at this point. Also heard some of the newer ACTIVE handsets cannot even be rooted.

As in most things if you not overdo it you can enjoy the benefits of better performance without risking your phone.My xperia mini is running up to 1200 (1024 stock). Also minimum speed 122 instead of 245.So better performance when you need it and lower consumption when phone is sleeping.Overall i got the same battery life, 2-3 days as with stock rom.The best thing to do is get an app that lets you make profiles.Like when screen is off min cpu 122 - max cpu 384 etc...
I don't know about these new kernels you're talking about but cpu throttling is something stock kernels do also (if by cpu throttling you mean cpu speed adjustment)

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.

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 .
What settings are best for optimal performance and battery life? I don't have any experience with this, and I don't want to screw anything up. I just got tired of my games always lagging, but I don't want a battery drainer. I dont believe I have a custom ROM. Thanks for any and all help.

SetCPU probably won't work very well unless you flash a custom KERNEL. You can mess around with it if you like and you'll probably won't mess things up. One thing I discovered before custom kernels came out is that you can enable the second core by enabling profiles in setcpu. YOu can see that in the menu option of setcpu for "cpu". That may help you in your games. If you set max at 1500 and min 192 initially, you'll see that next time you start setcpu, the max and min are both at 1500. I used another app like cpu monitor widget to see what was happening and low and behold the cpu was scaling 'properly', so I left the setting in setcpu at 1500 and 1500.
In the end...it doesn't work quite the way it was designed for and even with custom kernels we're seeing some issues with it, but mess with it, you may find that enabling the 2nd core will produce less laggy games. You'll have to judge the affect on battery.

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

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.

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.

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
