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.

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?

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.

I wanted to know some more about undervolting and was hoping someone could help and explain a bit. Basically, what I'm seeing is when I undervolt my device on the max side of things, eventually the device freezes and needs a battery pull or reboots. When I don't touch the max voltage values and only drop the min values the phone seems more stable and doesn't reboot. Can someone explain if my thinking of only undervolting the min values is correct and why this may be happening. Also, what would be the proper way to undervolt the phone? I have been using system tuner to do so on deck's 1.3 ROM using the Lee +sbc kernel. Thanks for taking the time to read this and for all the helpful responses.
Sent from my Decked Evo running Lee+sbc... It's easier this way.
I have this same question! I was trying to figure this out becuase the freedom kernels have something to do with under and over voltage to allow better OC? not sure on why the you would need and over voltage to over clock?...
What is your ROM/Kernel setup?
Remember that undervolting and underclocking are two different things. Over/underclocking, via apps like setcpu, raise/lower the frequency at which your processor operates. Over/undervolting raises/lowers the power voltage available to your processor at any given frequency. This can potentially cause problems if you have a kernel set to undervolt your processor while running an app like setcpu to overclock it. This may be why you are seeing issues with your phone.

OP clearly states he's running Deck's 1.3 and Tiamat 3.3.7 (aka LEE kernel)
OP should also state Deck's ROM version but I'm assuming 1.3d as it's most popular next to 1.3 Stable.
I'm running the same setup - Deck's 1.3d with LEE SBC. I'd like someone to explain (as the OP also asked) the difference between the MIN and MAX sides of the undervolting equation please.
(I do understand underclocking AND that it is a separate and different animal and for the record, my EVO is UC'd to 128/499MHz and using Smartass governor)
I'm just not sure what I'm looking at in the ST interface (what's the first number and what's the number in [] brackets?) and also not sure just why there is both a min and max voltage for each frequency and how it affects performance.
Thanks much for any inputs.

I use vipermod and terminal emulator for aosp roms its much more stable than using system tuner and you can drop all voltages with a single command it all depends on your particular hardware but typically around -100 the phone will lag or freeze i usually stick to -50 at stock voltages and -25 on overclock i never overclock over 1075mhz as anything higher and my phone tries to cook my fingers however now im oc to 1.6ghz on my et4g with a 200mhz min and it stays nice and cool like it was clocked at 1.2ghz stock the exynos is capable of clock speeds up to 2 ghz but the phone doesnt handle those speeds well similar to the evo not liking anything over 1.19 at 1.2 on the evo theres a good chance of frying the logic board or bursting the battery from heat if you overclock dont undervolt too much as it makes the processor get really really hot due to it having to work harder from lack of energy to power it

To answer the min/max at each freq min is the lowest voltage that freq will run while idle max is the highest voltage the freq will run while in use the voltages are depenedant on the load running at the particular freq ie how many process' are running the more process' the higher the voltage required to power the processor

I had a similar issue with undervolting and underclocking. I was setting my CPU min/max to 128-499 MHz and undervolting to -75 or -100 using Lee with Smartass v1. But I was getting too many random reboots and freezes on each ASOP rom I tried (e.g. Deck 1.3d, CM7).
I've been playing around with these settings. I changed my CPU to 128-576, no undervolting, and SZ 2.2.1 with SavagedZen governor. I haven't had any random reboots and my batter life is about the same...plus my phone is MUCH snappier. I'm still getting a little screen on lag but not nearly as much as I was at 128-499 and undervolted.
As a note, I normally run Deck 1.3d as my daily driver but for the last couple days I've been running KWIQ. It's definitely giving 1.3d a run for its money as becoming my daily driver.
Anywho, are there any rules of thumb with undervolting and underclocking? Like is 128 MHz is too low with -100 undervolting? Or are these things pretty much phone dependent? I know each phone seems to respond different to these things.

Thank you. That made good sense to me. Question then: is it suggested/typical to drop min and max by equal amounts or is it typical to drop min more (so there's juice for the proc under load but maybe being more aggressive with the sleeping/idle side of things or can the proc run at a given frequency at different voltages)?

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

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.

1.4 Ghz run stable down to 1.075 V for me.
With 1.050 V, is freezes after some seconds of the AnTuTu stability test.
I guess that stock voltage for 1.4 Ghz is 1.250 V, as it can be seen in arcos repo.
Nice under voltage
Yes, i am satisfied with the result.
Guess that 1.4 Ghz might be some kind of sweet spot, as my lowest voltage with 1.0 Ghz is something about 0.925 V.
Depends on the scenario, but the energy-per-cpu-cycle-ratio might be better with 1.4 Ghz after all, plus full calculation-thrust
Also had it running at 1.8 Ghz, and at one point with 2 Ghz, but i do not remmeber the voltages exactly.
Might have been something around 1.275 V for thw 1.8 Ghz one, also a good result.
By the way, there are quite big differences:
My Intel Core 2 Duo T6500 runs at its full 2.1 Ghz with the lowest possible voltage, 0.9250V, normal is 1.150V
On the other side, i had a desktop E6600, which needed much additional voltage for little OC, and was also bad for UV.
(seems as it was an exception, as they were known for excellent oc capabilities).

My suggestion is to use the numbers in the table I've posted. Use the phone for 2-3 days and see if it becomes wonky (random reboots, hangs, etc). Then try reducing the voltages to the "extreme undervolt" values in the graph I attached to that posting. Then lower the voltage for the 'sleep' frequencies first (369 and less), and slowly work your way to your maxfreq.

For me it´s a bit different. At the upper frequencies (1000-1400MHz) I´m at the extreme UV voltages. But for the lower frequencies I need to be +25mV above the extreme UV settings.
So there is noone who can tell what the sweet spots for all the frequencies are. Each CPU is different and everyone has to find out his sweet spots himself.
For stability tests there are even some apps at the play store, though I found the facebook app to be the best stability test app at all. Where all the stability tests passed the facebook app crashed if I undervolted a little bit to much.

As you can see in the table I've posted there, the undervolting varies according to frequency. I've undervolted by 175 on 1 GHz, and perhaps can still go 25 lower.

My suggestion is to use the numbers in the table I've posted. Use the phone for 2-3 days and see if it becomes wonky (random reboots, hangs, etc). Then try reducing the voltages to the "extreme undervolt" values in the graph I attached to that posting. Then lower the voltage for the 'sleep' frequencies first (369 and less), and slowly work your way to your maxfreq.

alright i'm trying with the extreme UV settings now (with +25mV for freq <1000mhz, will reduce later if stable) but i'm not sure if its the new Queen Anne's Revenge v2.3 rom, hurtsky's 2.1 kernel, or the usage of smartassH3 + sio that is causing my phone to feel less responsive (like takes 2-3x longer time to launch apps like whatsapp, boat browser, also launching incredicontrol twice in a row crashes incredicontrol lol). Is this a sign that I am undervolting too much? because I've tried raising all values by up to 50 from the extreme UV but doesn't really help. also tried changing smartassH3 to smartassv2 (my previous governor)

Undervolting doesn't affect performance, at least not directly.
What it affects are power consumption (i.e., battery life) and stability; some components within don't perform reliably with too low a voltage, and may internally reset themselves. This causes the kernel to go into panic (because the state in the kernel no longer matches the state of the hardware), and as a result, crashes.

ok. i used CWM to clear cache and dalvik cache, which forced the rom to "upgrade" again. The lag is significantly less noticable =)! Perhaps when upgrading rom (non-pristine), it is better to clear cahces
how sorry i'm a newbie here may i ask how to undervolt (or a link)? i've been having problem with battery life so perhaps this will prolong it further..
Download incredicontrol and u can use that app to set voltages. Follow graph given by pepo . Make sure u do not set as boot first. Test for like a day and if no phone hanging or restart then u can set as boot
Freq-voltage(mV)
122-775
245-775
368-850
768-900
806-950
1 02-975
1,11-1000
1,2-1025
1,3-1050
1,4-1100
1,5-1150
1,6-1200
1,7-1250
1,8-1325
I use these for my daily use, and it seems no problem at all.

Did anyone experience random Shutdowns or reboots after undervolting?

So, I was wondering if it is possible at all to overclock the Nexus 7 (2013). When I go to the app to overclock it (Yes, already rooted and installed busy box) I am unable to change max CPU's frequency higher than the default 1.5ghz. I also can't change the GPU's frequency over 400. Was wondering if there's like a limit to it or something. I was hoping I could overclock to 2ghz. Please help, thanks

Not to be mean or anything. But you really should not be overclocking your device at all when you don't even know what is required to over clock in the first place'. Let alone 2ghz.

Everybody has to start somewhere.
The kernel linked above should work fine. I would recommend backing up in TWRP/CWM before installing in case something goes wrong.
Why would you need to overclock this device? It already runs amazingly smooth with no lag whatsoever. What is it that you need the overclock for?

Most Stable Simple Kernel Tweaks (GPU, CPU, I/O, GPU Governor, CPU Governor, Voltages
Hey guys, I got really bored tonight and decided to do a lot of kernel tests and this is what i found to be the most stable...
CPU- 1.944 GHz with Intellidemand
GPU- 504 MHz with Ondemand Governor
I/O- Deadline with Read Ahead Buffer Size at 4096
Voltages- 12500 DOWN on every frequency
I'm running my Nexus 7 (2013) on the 4.4 KitKat
Build Number- KRT16S

So let me get this right, you oc your CPU to 2ghz yet you use a battery saving (read low performance) CPU governor?

Intellidemand is (for me) the fastest and smoothest overall with decent battery life as well...
Goes to show not all devices are the same, with Faux kernel on stock 4.4.1, intellidemand makes the device laggy in games whereas interactive is smooth as for me

I haven't found one game that has made this tab lag yet. Maybe next year there will be a reason to over clock the n7 2013. It's a great device that just purrs.

Well Beach Buggy Blitz would lag at times when there was a lot on screen (like the cave full of coins would kill my fps), This was on stock Kitkat, with custom kernels works fine with no drop in fps.
On a funny side note, cm11 runs everything lag free without needing oc or custom kernels, so maybe it's the stock kernel that's crap

ppsspp lags whilst it has better performance on Mali-400 & 450 and PowerVR SGX, what's a safe gpu overclocking speed 450Mhz is the Samsung GT-I9505G Galaxy S4 Google Edition
Nexus 7 frame drops
I have a Nexus 7 2gen and i hace notice a frame drop playing Shadowgun Kik Kat 4.4.2. I was so frustraded that I was starting to dislike the nexus 7, but searching I found this threat and read a comment were said about installing a different kernel so I installed ElementalX 2.6, since then I haven't expirience any frame drop playing shadowgun I really enjoy it now, maybe is bad stock kernel. I hope this threat help others
Sent from my Nexus 7 using Tapatalk[/QUOTE]
The only game I've played that managed to drop my frames substantially that I would notice was Real Racing 3.
Now, I have CleanRom and ElementalX onboard but haven't played anything to test the performance. 2.1Ghz and GPU at 500Mhz.
I am currently using stock rom with elementax kernel, cpu @1,72ghz and gpu @450mhz. When i tried 2ghz oc, everything worked fine, but it got really hot while gaming. So i´m asking me how dangerous it is to use such high oc values in daily life. How much could it decrease the lifespan of the components?

We can only guess. Keep it at 2ghz, and let us know how long from now before your CPU is baked, then we'll all know for future reference.
Also there is an inductive charging coil on the inside for wireless charging some day when they come out with the chargers, sweet ****

Actually it is an underclocked snapdragon 600, but i didn't know that this cpu supports a clock speed until 1.9ghz (thought 1.7ghz would be standard clock). So i think up to 2ghz there shouldn't be any problems and it's okay for everyday use. I've also heard of some rumors that our nexus 7 2013 contains a "second choice" snapdragon 600 chipset, which didn't fullfill the predetermined requirements and that's why it was rebranded as an s4 pro... but this is really unimportant and just speculation.

omg you certainly shouldn't overclock it because the SOC architecture is designed to run at optimal clock speeds... by overclocking it, you might shorten the lifespan of your device and you might even damage it permanently as well
