I have a og evo I want to know why when I overclock to 1.2ghz it freezes my phone why does it do that ?
Sent from my Nocturnal 4G using xda premium
Each Evo is different. Some of them can't handle that high overclock, or can't be undervolted very low. Each one is different, each has its limits.
I don't understand the big deal with overclocking. It burns your battery faster. I personally underclock, with little to no lag and is good enough for my casual gaming needs
Mine doesn't like a clock much at all. I can get about 1.1 before it starts locking up but even then it hangs a lot. I honestly don't see a difference from 1.0 to 1.2. Get a decent rom, good kernel and try out the v6 script an I almost guarantee you will like that better.

Well for us to be able to help you, you would need to provide us with more details on how you are trying to accomplish this.
I use no frils cpu but have also tried setcpu and viperMOD I know that's the best way to overclock but is very confusing. Have any step by step instructions to of to 1.2 I know having higher voltages helps as well.

Overclocking is overrated. If you need to overclock for every day usage, then something is wrong - at least in my opinion. Resource intensive gaming is different, but you shouldn't need to overclock for browsing, texting, casual games, etc.
Try out the V6 Supercharger script. I'm not currently using it, but have in the past and it seemed to make my phone more snappy. A lot of people swear by it and it's a great script, definitely worth a shot. There are other things you can do to speed up your phone without overclocking. I'd try other options first since overclocking will chew through your battery. Increase the dalvik vm heap size, there are plenty of free apps on the market to help with this task. Uninstall apps you don't use, I'll bet that you never use some of the apps on your phone. Back them up with Titanium Backup and you can restore them if you ever need them again.
In case you didn't already know, the Evo can't overclock past 1.2, I'm not 100% sure why - it has something to do with the processor.

I never oc over 1075 and only when plugged in if i play a game I need to oc.for I just activate my charging profile and plug up and play 1.2 ghz is a good chance of doing serious.damage as these older scorpion processors get very very hot at that clock speed so they lock up to try and protect themselves from heat damage or they shut down the phone 1075 is as high as you should need to go for any games the evo can handle on the subpar gpu

I'm pretty sure viperMOD is more for undervolting than overclocking, which are not suppose to be combined together. I am running vipermod with max voltages - 50. Other nite was playing snes9x and was getting some lag with a game so I bumped max CPU up to 1.2. Phone went into a bootloop and had to superwipe and reflash everything. Don't know if its b/c vipermod + 1.2 CPU or just bumping up CPU. Didn't try it again.

Get a shift. Mine runs fine at 1.9. But usually run it art 254-1200 on demand.

You can overclock and undervolt together just fine. You just need to ensure that every frequency has a high enough voltage to run the processor at that step. My Evo is overclocked and undervolted just fine, although IIRC I can only push it up to 1.1 GHz . My tablet is 1ghz to 1.6ghz and is undervolted as well, though.
merge rls 2.0, iron monkey, Droid overclock because of the profiles options. I set up four profiles including one for temp. sometimes i'm underclocking and sometimes overclocking but only up to 1.19 to prevent freeze and boot loops. Only downside is right at open Droid overclock needs su permission but that is my choice since profile changes at open.
Very snappy afterwards.

When I had the 4G, I was never able to go above 1118, or somewhere around that. It would have freezing issues.
On my evo shift, I was able to do 1.7 gHz (compared to stock 800 mhz) ok. 1.6 pretty reliabily, and I could run 1.5 all day long. Some guys could do 1.9. It just depends on the phone.
Actually overclocking and undervolting is counter-productive. What you should do, is read carhaulers and ropodopes guide over at vaelepak. Its give some good useful info about how to set up a good aosp rom. I'm underclocked, undervolted, and still getting 1400+ benchmarks. Check it out bro. You'll love the results.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all. Just checked my phone, my overclock requires an extra 25 mV for all three steps I've overclocked. 25mV isnt much, and it certainly isn't going to kill my battery that much faster.
Besides, the only time the CPU is going to be entering these high power modes is when it needs to do work, and it's better to do work as fast as possible to go back to sleep. Would you rather wake up, do a mundane task for 5 minutes, then go back to sleep or wake up, do a task at 2x the speed while only consuming 30-50% more energy, then going back to sleep after only 2.5 minutes?
HUGI is real.

First let me say I don't use viper mod or any voltage controlling mod.
On sense 3.0 roms such as mikg I over clock to 1152 and set the minimum to 384 and its smooth as butter. No problem and battery lasts all day.
On aosp however such as decks (I'm on it now) I underclock to 499 and leave the min at 254. Smooth as always and battery lasts forever.
Anything past 1152 is going to cause problems (at least in my experience) also the rom/kernel can effect how much you can overclock.

Its counter productive because it is giving less to something that needs more. (Don't take this post as me trying to be a ****. Just voicing how someone explained it to me a while ago)
Think of this as cars.
Lets say you have a nice fancy v8 mustang. Stock, everything is well, balanced.
If you start adding parts and get it pushing out 1000 horsepower (overclock) your most likely gonna need more feul (voltage) or at least stock amount flowing into the engine just to keep it running.
Now lets say you got that same 1000 horsepower gas destroying mustang and you start to lower the amount of gas flowing into the engine (undervolt (done in vipermod)) cylinders (CPU) wont get enough gas, it wont work, and your stuck going no where.
So if that made sense (did to me) then you can see why they are counter productive. Unless your using vipermod to overvolt (which idk if you can since I don't use it) then you can disregard this whole post

Your car analogy is completely irrelevant. You can look up the exact voltages that the CPU runs on at every frequency, *even when overclocking*. Overclocking an Evo 1ghz to 1.2ghz takes maybe a 5% bump in voltage, and that 5% extra power is only going to be used *when the CPU is running at max speed* (which is only when there is a lot of work to do), and even then, it's *still better to let the CPU run at max speed with a tiny bit more power consumption than to cap the CPU at a slower speed and make it work for even longer*. Intel calls it HUGI, Hurry Up and Get Idle.
I know what I'm talking about, and I wish people would stop trying to argue with me based off of second hand speculation. I do this for a living, after all. There is absolutely nothing wrong with overclocking and undervolting, and it's the best way to get the most battery life *and* performance out of your phone, period.

Hmm, *interesting*. I believe the best answer to the OP was covered rather well earlier. It's all about your rom/kernel/hardware combination. With all the variables to consider as relevant, your best bet is to experiment and find what works for your device. Don't check set on boot untill you are confident the set-up is stable. Higher is not always better with overclocking. My device runs blazingly well underclocked @768max. Gets insanely great battery @499max. However my quadrants are better @ 1036 than at 1190.
Great thing about android is you can experiment and learn through trial and error.

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

How much battery life can you save using setCPU?

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough
Is it worth it?
How do I go about testing the stability of the phone ( I don't want to reduce clock speed )
If you want your phone to work perfectly without loosing speed it's not worth it ( change wouldn't be noticeable )

If you're not sure about what you are doing it won't lower performance it will probably result in a lot of crashing and error messages, I personally think it's not worth it for the amount of battery you could gain ( few minutes )

Well, I have had it undervolted with -150mv in a week or something and I haven't experienced any errors and crashes. I don't have it for the battery, but for the temps.
Sent from my HTC One X using Tapatalk 2
I've been under voting my s3 747m for over two weeks now, between 75 to 300mv lower, at 1.89 I'm running at 1200mv, although I'm only running it at 1.5.
To test it I use Stability Test app, on scaling for 3 hour runs, it will stress all frequencies.
If you find a crash you increase the voltage at that frequency, BUT, the best way to test it, instead of using scaling test, use the burn in one, but manually set your speed and let it stress test XX frequency for a long period, this Is where I found the most of my crashes.
This isn't an easy or a quick job, it'll require a good weekend of mucking around. I have all my speeds down to 5mv increments instead of the stock 25 the apps give you.
But so far, I don't get voltage related crashes, only the random KP caused by cm10 bugs.
If people are interested in the voltages for this phone I could post them

I don't want to have a lot of speed with hardly to no battery life, i need a little speed plus good battery life if possible.

Im not saying there aren't any others as i have only used ktoonez's kernel, http://forum.xda-developers.com/showthread.php?t=1756776 simply because there is, IMHO, no need to. He has versions for each of the available android versions for the i747...obviously you would want to use the AOSP JB based kernel under CM10. Packaged along with the kernel is ktweaker which is an app that gives you control over the clock speeds, under volting, governors, schedulers, plus a bunch of other options. If you overclock your processor you are going to drain the battery faster, you can compensate for this by under volting the frequencies however pushing the CPU too hard can shorten the life expectancy and under volting too far will cause severe system instability. Im not sure how much experience you have with OC/UV'ing but its basically trial and error until to find the right balance of speed and stability that is right for you.Just be sure to read and follow his instructions carefully and dont mess with anything in ktweaker you aren't 100% sure what it does, and as always make a backup in your recovery before messing with system files.....happy OC'ing.

There is a thread dedicated to ktweaker settings on the i747 HERE that would be a good place to start and get an idea of what you are doing. There are also several topics that discuss the different governors and schedulers, what the differences are, advantages/disadvantages to each etc. You can also search google for a plethora of information regarding OC/UV'ing, although most of it will pertain to desktop processors and video cards. While the voltages and frequencies will be significantly lower the same principles apply with mobile device chips.

It's actually pretty simple. First off you need a kernel that allows undervolting. Secondly you need an application like an NSTools or STweaks however with STweaks the kernel has to support that application. Once you get in there and it shows your frequencies its going to show your millivolts as in mV. Take for example let's just say that you're 1.6GHz frequency is @1100mV you can take it down to 1075mV. And after make sure its stable if so continue to undervolt and so on and so forth. Now again those aren't real numbers. There just an example for you. Now there is a thing called overvolting which is essentially only used when you have a frequency that is unstable.

Some tips:
Don't make any changes to roms, mods, kernels, etc while testing undervolting. You don't want to introduce other variables during this phase.
Go by steps of -25mV to be conservative. Do -50mV if you want to be aggressive in your testing.
You know if you've undervolted too much if you start noticing laggyness, UI studdering, random reboots, and other unexplained problems. This is why you shouldn't make other changes during the evaluation, since you wouldn't know what caused the problem.
You will need more voltage at higher MHz. It's not uncommon to undervolt more at the lower frequencies.
Once you find a safe undervolt settings, it can be a baseline for other kernels/roms. You'll still need to verify it's stable.
