How do you overclock your EVO

Still learning in the scene but I rooted my phone sometime 1 month ago and now using MikFroyo custom rom. Now I hear you can overclock the device to get a better benchmark on the device. My question is how ??
Please be easy on me lol. I am coming from a iPhone which is pretty pampered over there.
Thanks.

Then what I am setting ? Like I see the max @ 998400 min 245000..... Should I change the scaling ?
thanks.

You need a custom kernel first. Developement section's got a nice selection, with tons of posts showing peoples set-ups.

Don't get too caught up in benchmarks. A better score doesn't necessarily mean it is faster in real world usage. More for braggin rights than anything else.
Welcome to the EVO forum.

Its a great way to heat up, shorten battery life and cause more force closures. Good Luck!

You can't overclock with a stock kernel. Like chris66 said you gotta go with a custom one.

Check out netarchys kernels, great work he does.

What is a safe range for battery temp.? I'm running in the mid 90s F. Sometimes it even gets up to 104 or so....... ?

cpu settings are built into CM7 now, thats how i manage it

That's normal. Basically, if you get to 50C (122F), then it's time to shut off your phone and yank the battery then stick them both by the window. Android will start *****ing at you that it's too hot at that point.

SetCPU

Okay, so I'm generally new to using SetCPU but I feel it could greatly help improve the performance of my device. That being said, I want to create a few profiles and was wondering if I could get a little help doing so. I'm not sure if this matters or not, but I'm running the Legendary ERA 2.2 rom + the latest Samurai SEPPUKU kernel.
Basically, these are the kind of profile's i'd like to setup:
- General profile, just for the usual facebooking and texting.
- General profile for just listening to music via last.fm/Winamp
- General profile for just for playing games
And finally... A profile to do all of the above without murdering my battery TOO much. As well as a profile for when my phone is not in use, to conserve battery.
I'd like to save as much battery as possible in the process of these things. The last time I tried to screw with SetCPU I ended up getting tons of random reboots, which completely made me change my mind about the app. With help on figuring these things out, I'll be able to come to a general understanding of what my settings should be for certain things and I'll be able to setup my own profiles for anything else I may need. Sorry for the long post, and for being such a newbie, but I hope I can get a little help here
Side-note: Also, I was wondering how you guys like the Shadow Kernel, as opposed to Samurai. So far, my ROM and kernel have been doing all that I've been needing them to do, so I haven't really felt the need to try it out. So any feedback regarding it would be nice, because I might be willing to give it a shot.
Really sorry if this is asking too much.

I'm sorry but your thread title is not in the form of a question. Thanks for playing our game though.
LOL.
But to answer your question, if you want to conserve as much battery as possible set each profile for the least max frequency you can stand.

I know that listening to music the cpu usually sticks to 200-400 mhz so if your not using the touchscreen and just shuffling id make your music profile 100-400 and when your on facebook or the screen is on id use 100-800 1000 if you need some extra speed . And for gaming id keep it around 1.2-1.5 if you need that much like emulators use a lot of cpu power I know cuz I still get lag at 1.4-.15 on n64oid. Also if you do go with emulatora sixaxis control app will be a must allows you to reconfigure your bluetooth stack as a address and you can then change ur ps3 controllers bt address to pair with ur phone. As for a general profile id use just the typical 100/1000 and undervolt as low as possible for example I do this
100 -200
200 -175
400 -150
800 -100
1000 -75
1100 -75
1200 -50
1400 -25
1500 none
Notice I don't use 600, 900, and 1300 cuz those crap my phone up for some reason don't follow these exactly as each phone is different just an example just test em and see how you fair.
Btw Voltage Control is WAY better

Thank you Biggoron, I'm going to get rid of SetCPU and grab voltage control now
And thank you for the suggestions, I just want to make my battery last as long as possible without having to go charge it every 5 minutes xD I'll give your suggestions a shot!
Also, I tried to read up on the undervolting/overclocking thread and ended up getting really lost. I'll have at it again, but for the most part could you give me a brief explanation of on demand, powersave, conservative, etc.. and which would be best for the ways I use my phone (stated in first post). Sorry for the hassle, I'm still learning! Haha x)
Sent from the one and only Legendary Samurai ;]

Govenros are basically how the cpu runs frequencies and depending on the gov it varies like ondemand it may ramp it up to the top when touch input is applied but drop down when its not needed. Conservative will keep it as low as possible unless you start using it and then it will slowly move up and the others are vairants of the two really there's a thread some where if you google it.
Id say lagfree if your gaming, ondemand for facebook, and conservative for music

Ahhhh dude your such a lifesaver, seriously. Thank you so much =)
Also, are virus protection programs worth having on my phone? I always considered them a waste of time, but nowadays I'm hearing a lot about them. What's your personal opinion on that? And also are there anymore apps you'd reccomend?
Edit: Also, what voltage should I use for when I'm asleep (phone inactive), or asleep (downloading stuff (like ROMs, etc.)?
Sorry for all the hassle haha, you've been such a help.

As for virus protection unless you watch an extended amount of pron then I wouldn't worry
For the most part if you stay away from black markets for apps you should be good especially those in which require root access.

Why is the default voltage so damn high?

I get having it be higher than necessary to avoid bugs... but the 153mhz CORE slot can go to 90mV down from 8-900. That's 1/10th of the original voltage. Why would Google/Samsung ship it using so much more than what it needs?

Those are MAX voltages...and I call hogwash on the 90mV, unless you are disabling smart reflex. Then I would want to see some actual proof.

Lower than 70mV is unstable. I didn't disable smartreflex, but even if I do it makes no difference. Maybe someone else can share their lowest voltage for this. I'm sure I'm undervolting it as it becomes quite unstable if I input 60mV, so obviously something's happening.
Yes, they're max voltages, but even with SR it doesn't go below 886 or something.

I find that tough to swallow. Did you actually verify the voltage with a kernel log?

What's the easiest way to do that? I'd like to confirm it myself. Like I said, I know it's doing something because at 50-60mV there are instant issues.

If memory serves, dmesg will log it.

Yikes. A lot of output and no 'grep'. Give me a minute.

You have to disable smart reflex for your voltage settings to work. It isn't going down to 90mv. Disable smart reflex and then set that, I doubt your phone will run.

Voltage Nominal=75000, Calib=75---, margin=38000
Seems to be the most relevant. And yeah, I've got it at 75 right now.
And I've disabled SR as well, it doesn't change anything. And the voltage settings definitely do work witohut disabling it as, like I said, going too far down will cause a crash. So obviously it's doing something.
Have you guys tried undervolting that far?
And I'm doing this with franco kernel updater. The widget is showing the Core voltage to be 75.

thats 900mV and 750mV. and there is a large variation between individual devices. some can handle much less and some cant handle a tiny bit less. but undervolting too much will end up using more battery to achieve what it needs to achieve from working longer/harder to get there. 90mV without or even with smart relex will cause your phone to freeze then reboot.

Why? I know that underclocking would do this - the time to finish a task at a lower clockspeed is longer.
I don't see how lowering the mV can possibly increase battery usage.

But mine isn't freezing until I put it at 60-70,V.

no, you are right. i didnt see that you mentioned core. after looking at the original post i see the core now. anyways, at that low a voltage it will operate, but wont be fully functional.
---------- Post added at 11:11 PM ---------- Previous post was at 10:53 PM ----------
anyways, i dont know what that app is reporting, but franco kernel can only be set to a minimum of 830mV. looks like a mistake or a bug in his app. im gonna email him.. https://bitbucket.org/franciscofran...e9aa9b26/arch/arm/mach-omap2/voltage.h#cl-184

It seems functional... I mean, clearly the GPU is working (and at that voltage according to the app) because the screen is on/ not artifacting.
Is it just incorrectly reporting it? Is there another way to confirm it? Dmesg was not clear.

check the link out that i just posted. franco kernel can only be set to a minimum of 830mV, the app is reporting wrong. its setting, but not actually setting https://bitbucket.org/franciscofran...e9aa9b26/arch/arm/mach-omap2/voltage.h#cl-184

So what is it actually setting it to? Because if I set it *too* low it still does give me errors... so how can it be both?

i think it gets set to 830. i let francisco know, we'll see what he says.

Alright. It's just weird. Because if anything under 830 is setting it to 830, and 830 is stable (because 95 shows stable) than how would 830 be unstable when the UI shows it as 40.
I mean, 90mV is kinda insane. It would definitely make sense if it were more like 830. It's just confusing.
Hopefully francisco can explain.

Hmm, then why does setting an absurd voltage like 200mV cause an instant reboot while I can set it to 830mV and it runs fine?

Yeah I can set it to 830mV and it runes fine. No issues until I drop to 60mV. I haven't reached a limit for any of them.

Downclocking to save battery live?

Hi,
I am running a wicked v2 rom, had an idea yesterday to try to downclock cpu to potentially increase battery live. Used SetCpu, set ut to ~1.4ghz, governor is powersave. No performace hit that i can notice, outside benchmarks. On my first day now, will see how it works out. Anyone done that, any statistics?

ive been doing this since the first custom kernel was released. you get a few more hours depending on how much you downclock

downclocking always worked on my nexus 4
On a side note doesn't the powersafe governer set your phones cpu to the lowest clock speed at ALL times. As in if your minimum clock speed is 300mhz then its going to set your phone there forever?

just curious why you would buy a phone with 4 cores clocked at 1.9 ghz and dropping it???
thats like buying a 500 horsepower car, and detuning it minus 200 hp... whats the point?? Im not cracking a joke, its a serious question

Well, the plan is to get a zerolemon battery when it comes out. And i really cant see and performance hit, otherwise i would not really sacrifice... Assuming performance doesnt suffer, why not squeeze some battery life out and run a phone cooler?

Cpu battery saving Freq?

Hello I am wanting to see the best cpu app for tuning plus what governor is best. All for the sake of battery save. Thanks I appreciate.

"For the sake of battery save", powersave is the best governor. And you hopefully just understood why questions like these are frowned upon.

i've messed around with ondemand and powersave, problem is whatever program/app u use will change the values but simply wont stick as theres something forcing the cores to jump to max freq when under load
so i quit and am waiting on a kernel or rom that will allow this type of customization.

But that's the thing if you read the other reply you will then see why I asked. Since there seems to be that the root cpu commands doubt stick and get overidden

try use 3C Toolbox
https://play.google.com/store/apps/details?id=ccc71.at.free&hl=en
this app can control frequency and governor for each core. use it on my late z1 compact. i havent root my g4 yet.
but speaking of battery saving, I dont see any big difference compared to untouched processor frequency/governor.
for underclocking the frequency, I can see theres no overheating issue on the phone (when heavy gaming or heavy photography, the phone will still heat up but not too much)
I believe custom kernel will help much in terms of battery saving.
you wont see much different with stock kernel tweaking. imo

@negeri: and, moreover, tweaking (customization+ powersaving) seems to kill the battery life.
Have to flash the new 10e and Xposed framework, I won't try to optimize things as all I get is a slow and laggy device.

Haha sure thing. Now everything's fine, I bet ot was a mistake to install Gravitybox + XuiMod.

What has helped was putting min freq to lowest and leaving highest in Max and setting on interactive.
