Question about setcpu and overclocking

I'm using kings kernel #5 and i currently have its over clocked to 720 (and of course profiles clocked under that) I was wondering would i have significantly shorter battery life if i clocked it up to the highest (1.119) and set it to conservative

You'll most likely freeze up and crash at the highest clock speed, that's what happens to most of us. But that really depends on your hardware... You MAY be able to sustain that, but there's really no guarantees.
What I do (and I have pretty good battery life, it's 9:36 pm here and I just now dipped under 20%) is let the kernel do it's own thing and only set up a screen off profile that maxes out at 460.
But yeah, higher clock = more battery drain.

I cannot get over 1.113, reboots constantly over that. I get amazing battery life and performance with what I am running below.

Oh I can run it sustained i have my charging profile of 1.119 and interactive. Its 11:15 and my battery just dropped under 50% (i like bragging) But i figure it i put it to conservative it probably wont ever need to really run at max will it? Im not 100% sure on how everything works just yet

The word of the King
When King released #5, he was specific in saying that if using SetCPU w/ #5, only use it to overclock, as the composition of the kernel handles battery life.
That doesn't mean you can't, obviously, but I'm just conveying what I read when it was released.

just sayin'

Oh well thank you i had no idea. I actually messaged him on here about the kernels

I honestly dont even know what kernel i should be using... I dont even know the difference between bfs and cfs

King's notes and his d/l site go into uber-geek detail on the differences - take a look. Short version (to my understanding and probably way oversimplified) is they do different things - battery preservation or speed or a blend of the two.
That said, the kernel you should use depends on the ROM and what's important to you [speed/battery/both] - certain kernels won't/don't/shouldn't work w/ certain ROMs.Take a read thru the development section, and read thru the 2 threads for King's kernels. He's got 5? (or more) kernels out in the wild. Between those two threads, you'll see where one set is for AOSP ROMs only, the other for Sense and/or vanilla, whatever.
I've made the error of bootlooping myself by putting the inappropriate kernel into a Sense ROM - fortunately I did no permanent harm - actually it was good learning. Why? Now I look for, and use, kernels specific to the type of ROM I'm using.
They aren't one-size fits all - don't make the mistake I did - read up on what's there and you'll see what I mean.
Kind regards.

Yea I learned that not all roms work... I have virtuous 3.0.1 and want performance but mainly battery life can you suggest a kernel for me?

Lee - best suggestion I can offer is for you to read up on the kernels available and choose the one that works with the ROM you are running, that gives you what you want.
The reading/learning will do as much for you as a super-speedy or battery-sipping kernel.
Good luck.

I've been reading but just can't find any real information

The Kernels King post are defined by whether they can be used in Sense or Vanilla. His AOSP/CM are for Vanilla Roms only, and will more than likely cause bootloops if applied to a Sense Rom. The HAVS kernels are for Sense only. I change out between 2 and 5 and can't decide which is better. I also never run above 1.15 or I get constant reboots. 1.15 still reboots, but not as often.

1.5 or 1.6 ghz kernel?

Is this able to be done and if so how do u go about compiling a kernel??
Sent from my SPH-D700 using XDA App

Yes it is able to be done.
Sent From My Evo Killer!!!

I've seen the 1.8mhz custom kernels over on the EVO SHIFT 4G thread and the stock speed of that kernel is only 800mhz...and if they can push that a whole ghz past its regular operating speed...then I don't think 1.5 or 1.6 would be out of the question...id love to see that (HINT HINT TO OUR DEVELOPERS!! ;-)).

The problem that needs to be overcome with the current 1.4 kernels is that we're already at the top of the voltage specifications for the CPU (per manufacturers dox anyway) to keep the phone stable at 1.4. All chips are a little different - some phones might be stable with less voltage at this freq or others might be able to handle a little more juice. But, we're already at a 40% overclock... How fast do you really need this thing to be?

I personally would not use it if it was overclocked that high. That is to much for it. And the Shift has a different chip in it so it can be different overclock.

Moved to Q&A. And it can be done if you want to fry your phone

Some phones can't even handle 1.2ghz cause of the ****ty silicone on there chips. This includes my phone .
Thomasskull666 as a 1.4ghz kernel released to the public but he has a private kernel at 1.48ghz. He's trying to get a 1.5 for the public. The 1.6ghz we had on eclair was found out to be a placebo cause of error in the coding. With the phone clocked at 1.6ghz it actually ran at 1.0 and the rest of the phone slowed down. It was like those cartoons and you see a man walking at a steady pace but the background was moving at warp speed.

That just seems too fast for this phone. Personally 1.2 GHz seems fast enough while 1.3 GHz is just a nice little cherry on top in terms of speed.

[Q] Overclocking the Evo past 1.19

So, Im sure this was answered somewhere, and I searched all over.
With that said, why cant the Evo be overclocked past the standard 1.19 or 1.2? I know stability is an issue, but there are other ARM processors that can OC almost double. Is the Evo ARM processor just not able to handle anything past that?
Does anyone know?
Thank you for the insite

You cannot compare the processor in teh Evo to other similar processors. Every single processor is different, and overclocking the evo past those speeds could brick it.

Why would you want to overclock that far? The Evo has no ventilation and crappy power management, even with an extended battery. You're taking an already unstable system and pushing it to the edge. Not only will your phone overheat and freeze, but you can permanently damage the hardware.

I know every processor is different and each one has their own limits.
There is always a risk of bricking and damaging the actual hardware, but what im asking is, in theory, and a practical test, can you push the evo processor past the 1.19 that seems to be the limit (im not talking about going huge, but is there a possibility of being able to hit the 1.5Ghz?). Because there are certain frequencies that are not stable, but ones slightly past that could be stable.
Just throwing it out there.

A car traveling at 120 MPH is not as easy to control as a car doing the speed limit.

try it out n see what happens n then report back ur findings for others that have the same question and cannot find an answer anywhere

I would, but all the kernels that the Devs have developed have either a limit put on them, or they havent been able to allow it to OC that far

I was wondering this too. It would be nice to have the option to push it over 1.19ghz, I'll be the test dummy.

My Evo can handle 1228 fairly well but can tell its not as stable as say 1190. 1190 MHz is no prob...1267 usually crashes after a run or 3 in quadrant. 1113 runs niiiice for me and my 0004 evo

I can run 1190 just fine. Can a Dev possibly create a kernel that allows us to go past 1.2whatever.

I can't go up to 1.19 stabley
Gimme a couple a days to come up with a new sig that is cool.

if I pass 1190 endless bootloop.... then ya gotta be fast and turn that damn thing down

I can go to 1228 MHz with Tiamat but it will crash and reboot once you do a couple of things.

despite the meriad of answers you have gotten, I have been running my Evo on Sprint lovers Rom, and KiNgxKernel-Evo-12-BFS357-2.6.32.25-Flashable.zip for kernal.
I have been overclocked at 1267 since the day the kernal came out. it is singularly the only kernal that has allowed me to do this without ever crashing. OH, and I'm using
SetCPU 1267 on both min and max and scaling set to performance.

Not going too big? Going from 1.0 ghz to 1.5ghz on a phone is like going from a civic to a v8. Alot of computer cpu's dont even overclock 500 mhz. I think you're expecting a little too much from a phone. If you want more, go buy a dual-core cpu atrix 4g or something. I'm a speed freak myself when it comes to cpu overclocking (mainly on computers) but 1.113 is plenty for a phone. It even runs fine at 600mhz. Dont get me wrong, it would be cool to get it that high, but your phone would hate you lol

Until HTC drops source codes you will lose camera and other things.

How did you overclock the CPU? I have tried the setCPU and it does not work, I have my Phone rooted, installed the crazy UNleashed rom (since uninstalled) and could not get the setCPU to overclock. Even though UNleashed is made to do that, and I have read others getting over clocked. I am running Synergy now, which I do not think it can Overclock the EVO, but I would like to know how you fine folks are accomplishing this. I would love to go 1.1 right now.

If you're using a stock HTC kernel, hit menu inside SetCPU -> Perflock Disabler. Disable Perflock -> Set On Boot. Ta da.

OC'ing

What's a safe level to overclock my phone to? I'm running the latest MIUI (1.9.16) with the lastest Tiamat kernel (1.1.3) I'm at about 1344 MHz right now. Can I go much highter?
Sent from my rooted, MIUI DInc2

From my testing, I've found there isn't to much to be gained going over 1.6ghz.
For a safe level I keep mine at 1.2 ghz. This has worked out well for me. Try different frequencies and see what works out for your needs.

I'm running JDKernel with the max set at 1.5 ghz, using the smartass governor. When I look at the "time in state" info, it usually shows about 75% of my time spent at 768 mhz. Seems to be working great.
Sent from my Incredible 2 using XDA App

Well, I tried bumping it up to 1.6, and I locked my phone and the screen turned off, but the keys stayed on, and it wouldn't come back up. So I pulled the battery and went back to 1.3 like it was before. Now its working great. I'm on smartass v2

If your having lockups, try installing Incredicontrol from the market and bump up the voltage on the higher frequencies 25-50mv, this should keep you from locking up. I do this when I use the performance governor and want to run Quadrant or Linpack .

I've been using SetCPU, cuz I couldn't understand Incredicontrol..... What's ideal if I'm running around 1.6 for voltage?

On the Jd Kernal, I'll bump it up to 1450 and go from there.

So, you don't know about for Tiamat? I'm using that one.
Plus, would anyone recommend using his Incredikernel as well?

I'll go about the same on the Tiamat. I usually will start at 50 mv over whatever the stock setting is on the kernel when running performance runs.
I didn't know that Chad had done a Kernel for Aosp romed Dinc2's. I know his Dinc1 Kernels were great.

I accidently had my phone at 1.9 for a day running jdkernel, no crashes or anything
Atm when my phone is charging, it gets bumped up to 1.4 and i have no issues at that speed.

When are we likely to see OC of Tegra'3?

Dev's are super awesome, don't get me wrong.

Android Revolution HD 1.2.1 using SetCPU, it also works on stock rooted ROM.
P.S. I also set governor from on-demand to interactive to give better battery life.

exactly I've been thinking UC would solve heat issues, 200-300mhz will not cause a major effect

But does setcpu support 4 core control? You may have underclocked 1/2 of the cores but probably not all of them
