How can i overlock my htc evo? Is it safe?

I've had my phone overclocked 15% for months now...I pre-ordered and picked it up on June 4th (the day they were released to the public) and it's never been replaced. I rooted it right away using the engineering hboot method, and I immediately went to a rooted stock rom with a kernel that'd allow overclocking the very first time I saw one posted on this forum. I've never been able to run it at anything higher than 1152 mhz, but I've also never had any stability issues at 1152 mhz. I also allow it to go as low as 128 mhz all the time.
Since then I've played with various roms, and various kernels, but the first thing I've done when changing any rom or kernel, is always set the min and max CPU speeds again, and decide which governor to use. I've also always played with the undervolting strategies, from static to HAVS, and I've always been able to get away with the most agressive stuff posted without any stability issues.
Your mileage may vary, but thats been my experience with an overclocked Evo. I will admit I can barely notice the performance difference from 998 mhz to 1152 mhz, but I actually notice a battery life improvement...get it done faster so the CPU can go back to idling at a low frequency as soon as possible mentality I guess.

please watch what you say here. its not going to get you any help to curse and swear at other members. last warning

@MikeOD, which governor and what governor parameters have you found to work best for you?
I think the whole overclock boils down to what you do with your phone. If nothing overly cpu intensive, then there's likely to be little gain in the amount of saved time.
I actually have mine under clocked at 921 Mhz (came that way in the rom initially). UI was fluid enough and everything still seemed to work well/responsive. I get slightly better battery life too. Noticeable in the rate the batt % declines during active tasks (web browsing).

Overclocking question, stability?

Okay, so my question is basically how stable is overclocking your g2? I typically keep it at 800 when I use my phone normally, than 1.5ghz for games. I wante d to keep my g2 at 1.5ghz forever.. is that bad?
My battery obviously increases in temp..

I just use 1GH. It's enough for all game now. and didn't see any bad to battery or phone

I've had my DZ for about three weeks now and all this time I've had it consistently overclocked to 1843MHz. At that high of a speed, I had to let the phone cool down after 20 minutes of use.
Just today I flashed pershoot's 1516MHz kernel and noticed no heat issues after ~45 minutes of consistent use (temps < 40C).

I have had my g2 for.... However long they been out. I have always been overclock to at least 1.5 with zero heat issues. I ran 1.8 and even 1.9 for a good long time as well. Those speeds have heat issues ones that required a battery pull a few times because it started heating up faster then i could shut down the phone. If your going to OC at those speeds makes sure you set temp profiles with alarms.

ARM processors, like our snapdragons, are a lot more forgiving on the overclocking front than what you might find in your desktop, for instance.
I still treat overclocking on my phone like I do my computers, though... setcpu has a stress test built in that you can use if you're curious how "stable" your overclock is. but in my experience, I've found that you can get away with just playing around with it and using the phone normally and seeing how it reacts to different clockspeeds.
right now, I run it at 1.1ghz (24/7). I have run it at 1.5ghz (24/7) in the past for PSX/N64 emulators, but I've found with my new setup (pretty light; no widgets, very few things going on in the background, stripped as many unnecessary apps as possible, and not using any animations or fancy bits) that 1.1ghz is more than enough to be able to play the games I play on any emulator smoothly.
you should be fine at any speed that is currently available in the overclocking kernels we have with the exception of flippy's 1.9ghz kernel, which does require some monitoring to keep things cool and stable. but it still does vary from phone to phone. if you're running at 1.5ghz and the phone isn't doing anything wonky, then you shouldn't worry about it. if you're running it at 1.5ghz and you're experiencing stability issues, random force closes that aren't fixable through conventional methods, or heat issues, you should probably back off a bit.
some people have problems at 1.2ghz, some people are running at 1.9ghz all the time and never have problems... just find what works best for normal usage with your device and go with it.. it's not like we keep these things for more than a couple of years anyway, and the processor will be capable of handling the [stable] overclock for that period of time.

im always at 1.2ghz. 768 as min, interactive gov (when i use CM7) and battery has been fine, havent noticed any major issues. hard to tell if it was the rom bugs or OC being the issue but from what i read all my issues others have at various speeds so im guessing it was rom related

i think it depends on the rom.
when i use the Pyromod rom i dont need overclock but for other roms like sense roms those I require OC. I always keep it at 1400 when needed.

[Q] Decks or Cm7's best kernel (SVZ vs Tiamat vs Godmode)

Hi guys, i've been looking into many threads and reading a lot of posts and asking a lot of questions. however i know that their is not for sure answer to this but i would like to see what you guys believe to be your best kernel for battery and performance. i have seen people say it is Godmode (v9), Tiamat v4.1.0, Tiamat v3.3.7, and Savaged-zen v2.2.1. (ALL of these ARE with SBC-OFF). i just want to know what is you best kernel at the moment for your evo with decks or cm7.
Side Question: what is the difference between the governors: (Interactive, InteractiveX, Smartass, SmartassV2, Savaged-zen, and Lag Free)?
- Thank You

I like Tiamat 4.1.0, but I can't help you for your side question. I'm still new to development and rooting

i know you said your new but im just wondering have you tried any other kernels?
and what is your battery life with Tiamat 4.1.0

I've used damn near every kernel available for CM7. And by far the BEST kernel for battery life is Savaged Zen. I'm on a stock battery and it just seems to last forever. Add to that the fact that the battery lasts all day without sacrificing performance at all. Every phone is different and you may or may not see the same results. This is just what has worked for my phone. Honestly, your best bet is to get flash happy with various kernels until you find one that gives you the performance and battery life that you're looking for. By the way, I use SVZ Manager with my kernel so that I can toggle SBC on and off as I please. It's a nice apk that gives you some flexibility.

I've tried Tiamat 4.0.8 and a Savaged Zen kernel (can't remember which version). They both gave me about 12 hours of battery life on an average day(for me). But an average day for me is going to school, so I'm not on my phone as much. I haven't gotten to really test the battery life because I haven't looked at it on the weekend when I'm not at school. But like Concordium said, every phone is different! Try them all!

at the moment i am using the latest svz kernel with the svz manager as well. i have been flashing many kernels and for a while i was happy when i used the godmode kernel my phone lasted me 1 day and 6 hours, however he is no longer updating his kernels =( i'm hoping to find another kernel such as that one that will give me around the same results ^_^

I liked Godmode. But it didn't seem to give me as good battery life as savaged zen has given me. Each phone is different though.

well im testing this one out at the moment and it has given me so far 17 hours and 20 mins, still at 31% battery, im just not sure if it'll do better than godmode did, at the moment im running it on the smartass kernel and i ran godmode on interactive so maybe that is the prob... however another issue is i've heard that svz is no longer updating as well... do u know if this is true? and one random thing that only a few people have told me is that they run on performance and overclock their phone and get the best battery from it, is that possible or a lie?
Edit: it lasted 20 hours and 53 mins, so since it didn't do as good as GodMode did then im gonna try the tiamat 4.1.0 now cause it has first place in the poll atm.

Its true that its not being updated anymore. It sucks but I plan to ride it out as long as the kernel functions properly with CM. Once it starts screwing up then I'll switch.
Those who say they get the best battery life by overclocking and putting their phone on performance are full of crap. Performance governor is basically the polar opposite of Powersave. Performance keeps your cpu constantly running at a high frequency. Logic states that overclocking to 1.13 ghz and perpetually running at that frequency requires more power than running at 245 mhz. The more power required the less time your battery will stay alive. Powersave gives you best battery life but gives you crap performance. Interactive, Smartass, and Ondemand give you a balance of performance and battery life. Performance gives you the best performance but crap battery life.
By the way, do you really need a phone that can stay off the charger for more than 21 hours? :-x

no i do not but! 3 days of the week im at school doing nothing for 8-10 hours so... i think if my phone can run longer than a day w/o charging then it mean i can play games on my phone while waiting and by the end of the day i'll still have battery. and does it make sense for someone to get better battery life on interactive than on smartass?

Well Smartass, as I've heard it described, is sort of like Interactive 2.0. It's basically the interactive governor but better. Unfortunately, I do not know enough of the exact specifics of the governors to tell you which SHOULD be getting better battery. I would just run each of those governors and see which one works better for you.
And I thought your phone already lasted 21 hours with a decent amount of usage. You need to test the governors/kernels in the exact situation you are going to be using the phone. Interactive, Ondemand, and Smartass would all manage the phone pretty much the same if you just leave it alone and let it sit till the battery drains. but they each manage the power allocation supplied to the cpu very differently during actual use. One ramps up the voltage quickly while one scales it up more gradually. So take your charger with you to school, in case you run into trouble, and use the phone as you believe you will be using it in the future. Then you'll have a more accurate idea of which setup works best for you.

just wondering what do you keep your cpu settings at: the governor, cpu min & max?

When I am plugged into my wall charger I keep it at 1113/245. I use Performance for benchmarking and testing since I don't need to worry about battery life and Smartass when doing everything else. For normal every day use I have it at 1036/245/Smartass, Interactive, or Ondemand. I don't really have a preference between the three governors since they all make my battery last more than long enough. So it usually comes down to whichever my clumsy finger happens to accidentally select first. If I happen to not go home and need more life then I'll drop to 729/245/Conservative or Powersave. I use conservative if I still need to be able to use the phone a bit and powersave if I want my phone to just sit there and look pretty till I get back home.

You're not bugging me man. This place exists so people can ask questions and get help.
I keep my min at 245 because I've read, in multiple places, that allowing it to go any lower is not something your cpu really appreciates. Just like there is such thing as too high with your clock speed there is also a too low. And everywhere I have seen 245 is the preferred low end. I am not 100% sure as to why but I would assume that it is because your cpu needs at least a certain amount of power to run the basic processes required to keep your phone functional. Similar to a computer. Lower the cpu too much and it just can't do what it needs to.

I don't remember there being a thread dedicated to this. I just remember it from posts I saw within different OC/UV threads. Do a Google search for it and see if that returns any results. Like I said, I doubt you'll find a full dedicated thread. But you may be able to find the individual posts where it's mentioned.

[Q] Overclock

Well i have a phone, and in that forum members says that Overclock the cpu shorts the motherboard life, is that true? and for those who are using Overclock, do u really feel something diferent with the performance of the tablet? or do u see something wrong with Overclock? like random reeboots or makes the tablet hot? Im thinking in OC or not my tab, so i wanna see the experience from other members, thx in advance. :good:

I cover this in the guide I wrote in general (which has been pushed down quite a ways) but anyways here goes another version.
Overclocking varies from device to device, even of the same model. Variances in tolerance is on a per chip basis, as long as they pass within a certain range they are sent out for production in devices. Overclocking in general is within means of the chip's abilities, if it isn't, you'll know it. Generally speaking, 1.4 GHz is perfectly fine on our devices. 1.5 GHz is also usually ok, but is the upper end of what the Tegra2 can usually tolerate. Few an go past 1.58 GHz, my old G2x's tegra2 could hit 1.7 GHz,but that's well beyond "normal" range.
Overclocking a device is the same as overclocking a PC, you need to be careful with it. Don't just ramp it to 65% overclock and expect it to run fine. Every chip is different. Do it in steps, and test each step before moving on. Test it in normal usage, test it in heavy usage, gaming, etc.
An overclocked device will certainly run hotter then normal, it's running faster, drawing more power, and that creates a hotter running core, no way around it. Keeping in mind there is no airflow in these things, that makes the biggest enemy to CPUs even more dangerous.Does it run so hot that it can shorten component life? Sure it can. Will you still have the device when it happens? I doubt it. Likely, we'll be on Tegra5 before it even begins to show signs of stress.
One of the nice things, though, is our CPUs range so much in speed according to load that just because your Max is 1.5 GHz, it doesn't always run there. Most times, it won't even be in the overclocked speeds. Does it run faster? Sure does. Benchmarks will raise nicely, and games that maybe got choppy before will smooth out, movies that couldn't play well will be fluid, the heavens will align, mankind will discover world peace and I'll win the lottery.
All that being said, I don't usually overclock, in fact I tend to underclock a little to 800MHz. Its usually sufficient to do normal tablet stuff, and I adjust the speed according to what I require. If my movie is lagging, I'll bump it up until it smooths out. Same for a game if it needs it.
In the end, its all personal choice, really. Just because you CAN overclock, doesn't mean you NEED to. IMO a well tuned governor will give as good a result as overclocking in normal usage, and a good I/O Scheduler will also help alot, without adding anymore heat or stress to your device.
TL;DNR:
Overclocking is fun. It causes more heat. It likely won't explode within the time you own it. Or your children. Your battery will suck.

thanks pio for the answer, thats what i needed to read, cuz usually when u talk about OC its like "yeah dude, OC its "tha greeeeeat doi it dude" or something like "dont do it!!! u will decrease your tablet life" and yes, i know that devices are way to diferent even if they are the same model, and also im agree with u, governors and I/O works better than OC but we dont have many for our device, i miss the smartass v2 governor,or the brazzilianwax too, but well, hope someone can port it for us someday.

[Q] Decent CPU Temp (Heavy Load) For Nexus 7 2013 with Root & Stock 4.4

Hello everyone! I am very, very happy because i bought a Nexus 7 2013 a week ago. That same night I got home from the shop I knew it was getting root permissions. So i did the rooting method with WugFreshes toolkit and it worked like a dream I must admit. TWRP and Superuser installed in a flash.
After root permissions the fun started - Custom Rom's, Mods, Tweaks you name it. I am currently using Stock Kitkat 4.4 ROM with many tweaks:
PureGraphic HD
PurePeformances
AwesomeBeats
PureAudio
I have the Franco Kernel and it's great. I have had no issues what so ever so far. It's smooth, fast and responsive. Games run extraordinary fast, I can amp up the graphics without to much frame drops, this includes games like GTA SA, GTA VC, Modern Combat 4 and N64/PS1 Emulators (and yes i own the roms :highfive. Back to the Kernel. All Wireless adapters are working (bluetooth, wifi, nfc etc), and wifi seems faster. Battery doesn't drain very fast at all, even with intensive load. But here is where my question actually is ...
I do understand that this question has been answered somewhere else in the Nexus 7 2013 forum, however can someone tell me my question in more detail? Thanks. :good:
Q. My question is, between what cpu temperatures is safe for my nexus 7 2013 to play intensive games at (etc emualtors, gta series, MC4)? What temperatures should i be alerted at. I am currently running GTA Sandreas and emulators at around 50-65 Degrese celcius (yes that's right celcius us auzzies use the metric system :silly: . )
Also if i overclocked it to 1.7GHZ then what would a stable temp be while idling and heavy load? (thanks!)
(last minute edit... Also what CPU is really used in this? People say it's an undercloked s4 pro or something? So if overcloked back to 1.7GHZ it'll be fine? Right?...)
Other information consist of:
.All the mods i said i have, stated earlier
.Franco Kernal
.Wireless devices faster tweaks
.Use 4x MSSA
.Warn at 65 Degrees Celcius
.Other small mods i can not think of...
.Stock GPU & CPU clock speeds
If anyone can ask my question A.S.A.P it would be greatly appreciated, i am currently new to XDA but not the the Android OS. And to all of you whom think Android is a terrible OS go get one of the most biggest fails since Apple Newton the iPad.
P.S The XDA forums is great, and everyone on here deserves a good old beer. If this thread violates any T&C please go right ahead and delete it. Thanks so much,

How come nobody has said nothing to this question?
Btw, my cpu hit 91º C this morning while I was playing nova 3 and I was using an overlay to see my gpu frequencies and usage. I think is too much.

I personally wouldn't worry about cpu temp that much. All the developers of custom kernels will set the thermal limits to whatever they think is appropriate. A much bigger concern than the cpu temp is heat being conducted to the battery. I would make a point of keeping the battery below 120F and I personally don't want to see over 110F (around 45C).

The overlay thing I was talking about earlier was the cause for that cpu temp, it used like 2 entire cores to function, without it, temps are more stable, can you believe that the tablet actually kinda burned my fingers if I pressed too hard? That's insane.
Now, I understand that the battery's temperature is something important, so you don't ruin your battery lifespan, but how come cpu temps don't matter as much as battery's does? What's the max temp for these devices?

I'm going to "guess" and say somewhere around 100C for the cpu. Just a guess. 60C for the battery would absolutely be bad news. 50C would make me nervous. Also the cpu will start to get throttled (underclocked) once it gets up to a certain temp, And once it reaches the max temp the cpu will get shut down and you will have to wait for it to cool down before it will boot back up. I would worry about the heat affecting the motherboard and the components on that before I would worry about heat damaging the cpu.

I am currently running GTA Sandreas and emulators at around 50-65 Degrese celcius (yes that's right celcius us auzzies use the metric system :silly: . )
Also if i overclocked it to 1.7GHZ then what would a stable temp be while idling and heavy load? (thanks!)
(last minute edit... Also what CPU is really used in this? People say it's an undercloked s4 pro or something? So if overcloked back to 1.7GHZ it'll be fine? Right?...)
Other information consist of:
.All the mods i said i have, stated earlier
.Franco Kernal
.Wireless devices faster tweaks
.Use 4x MSSA
.Warn at 65 Degrees Celcius
.Other small mods i can not think of...
.Stock GPU & CPU clock speeds
If anyone can ask my question A.S.A.P it would be greatly appreciated, i am currently new to XDA but not the the Android OS. And to all of you whom think Android is a terrible OS go get one of the most biggest fails since Apple Newton the iPad.
P.S The XDA forums is great, and everyone on here deserves a good old beer. If this thread violates any T&C please go right ahead and delete it. Thanks so much,

Theorically speaking, the safe working temperatures would be the where the thermal limit is which is around 105ºC.
However, it doesn't work like this because heat spreads to other components and more importantly, it spreads to the battery and we all know batteries don't like hot temperatures since it drastically reduces their life span and charge capability.
On practice, I would say keeping your CPU below 70ºC which will result in a colder battery aswell is the sweet spot.
On the Overclock matter, I have mine at 1900'ish Mhz and my GPU is at 490'ish Mhz and I haven't experienced any abnormal temperatures while runing benchmarks. Infact, the temps were kept below 50ºC which is more than fine.

I'm going to "guess" and say somewhere around 100C for the cpu. Just a guess. 60C for the battery would absolutely be bad news. 50C would make me nervous. Also the cpu will start to get throttled (underclocked) once it gets up to a certain temp, And once it reaches the max temp the cpu will get shut down and you will have to wait for it to cool down before it will boot back up. I would worry about the heat affecting the motherboard and the components on that before I would worry about heat damaging the cpu.

I think the battery burns like hell when you're playing and charging it at the same time, am I right? I wonder, if the cpu and gpu are underload, the battery will drain quickly, does this mean that this produces more heat to the battery? How does that work.

The overlay thing I was talking about earlier was the cause for that cpu temp, it used like 2 entire cores to function, without it, temps are more stable, can you believe that the tablet actually kinda burned my fingers if I pressed too hard? That's insane.
Now, I understand that the battery's temperature is something important, so you don't ruin your battery lifespan, but how come cpu temps don't matter as much as battery's does? What's the max temp for these devices?

Thanks m8. I don't have to worrie about it anymore... The Nexus came to a screen smashing end...
