Clocking: Do you OC or UC? What are your thoughts?

Do you overclock or underclock? If so, to what point? If not, why not? What clocking profiles/situations do you have set up? Share your thoughts and experiences.

EDIT:
Below is the setup that has worked best for me, in terms of performance and battery life. I seem to have found a good balance.
1.2 GHz/245 MHz (Conservative)
Profiles
Screen Off - 768/245 MHz (Conservative)
Charging - 1.2 GHz/245 MHz (On Demand)
In Call - 1 GHz/245 MHz (Conservative)
*Profiles are ordered in terms of priority (e.g., if I am on a phone call and my phone is charging, the charging profile is activated).
*I'm also undervolted.

I keep my phone at ~.7GHz (underclocked) when on battery, 1GHz when on charger, and have profiles for medium (~1.3GHz) and max OC (~1.7GHz), as the kernel will allow, in case I need the extra power for something (like FPSe, chainfire, etc).

I keep mine at 500Mhz...gingerbeast is so beastly it can run decently even at about 200Mhz, I only use maximum...1900Mhz when I am showing off.

Damn if it doesn't. Never tried it but since you said it I figured I'd test it. Typing this this at 245mhz, and it actually functions decently, even scrolling this page. I tried this with my captivate and it wouldn't even swipe screens. I'm kinda amazed right now.

I keep mine at 768 Mhz when on battery. Just to save some power. But i could even go down to 368 Mhz (which i have <50% battery) and it runs decently. I'm using CM7.

i use LeeDroid's GB rom setting smartass setcpu at 245-1036 MHZ
battery can last long time

is there a free version because the only one i see a paid version

Im at 1344mhz daily with absurdly outstanding battery life on leedroid 3.1.1. And I'm using antutu CPU master cause setcpu wouldn't let me adjust the slider. No problems whatsoever.
sent from my Inspire 4g - hacked and slashed - Leedroid_3.1.1 - 1344mhz

Before my phone got jacked "another on the way" i run TPGB with ~1.5ghz top and .232ghz low. Smartass govener, and i use my phone alot. I easily got over a day. Thats with tethering-games-email-calls-messaging,
Sent from my VEGAn-TAB using Tapatalk

I was running at max OC (1.8Ghz with LeeDroid's kernel) for a little bit, but realized I didn't need the speed. Since I'm a PC overclocker as well, I couldn't just let things be at stock, so now I'm at 1.267Mhz max, and .245Mhz min. I'm doing my best not to bump it up more, and going to see how much I get out of my phone. I'm a very light user most of the time, so it's sometimes hard to gauge.

I overclocked for the same reason I OC'd my PC, because I could. That said, I'm running MDJ's kernel on Inspired Ace with the smarta** governor set at 245 min and 1400 max.

Seeing several people using smartass governor. I've been using ondemand....I'm gonna run smartass today and see what happens....
Sent from my Inspire 4G

Mine is at 768 all time, with just one profile that kicks when battery heat crosses 46 C that sets max speed at 537.
Adjusted both to 614 and 384 respectively after looking at above posts.

OC'd and [email protected]
using setCPU and being on CM7, i overclock to 1.7 ghz while the screen is on, using the interactive gov. i also set up a "screen off" profile that is underclocked to 247? mhz so that while my phone sits in my pocket for the majority of the day or on my desk, etc, etc.... it conserves quite a bit of power.
ive been using this set up since i got my inspire on cm7 (whenever that had its first RC) and im getting anywhere from 48-60 hours of usage.
my daily usage includes: tethering, streaming audiogalaxy, ghosttown, pandora. camera stuffs, calls, texts, 2 email accounts syncing, twitter, facebook, calendar, palmary weather updates, and much more stuff. so im going to stick to this set up until someone says they can get more usage with all that going on.

I run min(250 IIRC) and max(1.5) using on-demand.

I was overclocked at 1800 but my phone would freeze sometimes to where i had to pull my battery. So I tried 1000 but 2 days and then 1500. I noticed little difference in battery us and speed. I stuck with 1500 but after reading this thread i am gonna try 750. I never used any battery monitoring widgets. Im gonna try that. I use Leedroid GB btw.

I'm running at 1.2ghz with Coredroid and am happy.

Undervolting pros vs cons

What are the benefits/downfalls to undervolting? Does it save battery life or make the CPU work even harder? I'm using AlienMinds latest 1.2 with the -50 UV mod. Just flashed the volt mod this morning and haven't really had time to monitor the results.
I'm a noob to most of this stuff so if anyone has an answer or insight that would be awesome.
Sent from my Inspire 4G using XDA Premium App

From my experience with it, it helps. Before I did the tweak I was running CM7 stable and my battery would brain very quickly. After I flashed LorDModUE v3.1 with killersloth's UV my battery lasts way more than it used it. I think with a combo of undervolting and SetCPU profiles makes for a good experience.

What is Killersloth's UV?
I use vipermod to adjust voltage. Using Lordmod UE 3.1 with -50.

Im running Gingerbeast OC'd to about 1250 off charger and Using Pinky's undervolt script and I get nice battery if I am not "using" the phone as a Laptop/PSP. lol else it dies no matter what you do.
If I just used it for text here and there and a few calls It would last 2 days easy.

So you tried undervolting and now you are stuck in boot loop? Did you take a nandroid?

Yea i fixed it but I still have the same problem with signal. Before undervolting I have great signal. Just wish that I could have the best of both worlds

I would try consulting some other users that use the latest MIUI. See what they are using that works. That what I did with to get my CM7 up to speed.

Using SetCPU and the profiles works wonders for battery life.

I think undervolting will give you less heat? (well on computer stuffs it does)...
and saves battery, but undervoltting too much can cause unstableness..
DOes anyone know what happens if you undervolt too low?will the phone crash and will it revert back to the previous working settings??( its like this on pc).

1.9 GHz

I recently overclocked my inspire 4g to 1.9GHz on the virtuous unity ROM its quite stable and can be used on a daily basis.
I've been getting a average of about 3000 on quadrant professional.
Sent from my Inspire 4G using XDA App.

Just because you can doesn't mean you should. You're talking a 90% OC w/ ZERO added ability to dissipate heat generated by the processor and that equals a short life.

This. I mean I can understand a modest overclock, like 1.15 or 1.2, but 1.9? Asking for problems..1.9 OC sounds like you're fixing up a small grenade over there ..to each their own though..

I don't run it at 1.9 but it can be done, I runt it at 1.1 regular.

i can't imagine battery life is great running it at that speed either lol. i set my max at 1.2, i'll see if i even want to keep it at that.

I have to agree with you here. If it can't run well without OC then there is a prob.

i average 2500 quadrant on absolution at 998mhz. so i dont see where doubling the clock speed is worth the 500 quadrant.

Would it make sense to determine your max stable overclock and then tweak a governor (like ondemandx) to only kick in in extreme circumstances? I don't know the exact settings for something like this, but I image that it would be possible. Does anyone know for sure?
---------- Post added at 10:34 AM ---------- Previous post was at 10:29 AM ----------
Forgot to ask, what is the best indicator of temperature? I've seen the battery temperature. Is there a way to actually check the CPU temp?

I don't over clock, at least not intentionally. I guess some roms may do this. Phone gets damn hot in the car if on the charger and I will get a random reboot occasionally, so overclocking us just going to make that worse and I have no problems running any apps speedwise.

Set cpu

Whats the best scaling for set CPU. I am running MIKrunny rom.
Sent from my PG06100 using XDA

Well there are a lot of variables. Also, weather you want to lean towards performance, battery life. I'd say a good starting point is the default settings on MikRunny. 245mHz Min and 1.2gHz ( 1200mHz ) Max. Interactive and Ondemand are both good choices. Just bump it up a little at a time if you want a little more performance. Also, on MikRunny you have the option of setting the Battery Performance Levels to.

Your going to have to experiment a bit to figure out what's best for you. Because of the variables involved, there isn't just one setting that is going to work for everyone. I prefer SetCPU as an OC control.

No frills is the boss cpu adjusting app i.m.o... Setcpu has been known to drain the battery and also doesnt let you change your i/o scheduler... No frills has everything but voltage adjustment options, and if you want voltage adjustment options, antutu has a cpu app that also includes that feature...

It depends what kernel. X99percent has his on deadline but cfq works ok. Most sense kernels don't include bfq but bfq tends to drain battery more.

yeah honestly man its better to just start playing with numbers, i have 2 EVO Shifts right this second and one on 1.5 ghz runs just as good as the one clocked to 1.7 its all in how the phone decides to use that kernel, also the difference in my shifts is one HATES Dodges ext4 with a passion the other HATES X99 with a passion, its nothing against either dev because their both great, its just a limitation of phone, these processors wasnt meant to be cracked up by more than 125% id say a safe max speed would be 1.2 like the Kingdom since it rocks the same hardware as the shift just clocked faster. but i dunno man thats my 2 cents ive taken a big break in android and xda so maybe my thought process is off just a bit

I have a rev 0004 so I'm guessing you have two shifts that are different revisions like one is a 0004 and one is a 0005. And what do you mean they hate the kernels? You get lockups or something?

luck of the draw
Mines revision 4 runs great on either kernel. Lucky I guess.

so what exactly does this do for the performance of your phone? Is it just apps opening up faster and games a little better?
I understand the performance gains in cpu overclocking for computers in that you get faster encoding for videos, maybe a few more fps in gaming etc but how noticeable is doing an overclock for your phone?
Is it more of a just because you can or is there a real benefit to the user that they can notice?
A 30% overclock on your PC might give you 10-15% better performance but does that equate to similar improvements with a moving to 1.5 or 1.78ghz on your phone?

It's a balance there is only so much you can get out of the CPU in anything once it passes the threshold you get less from it more heat less life we are at 1.2 default I would say after 2.0 we won't get much more but a dead battery is 3 hrs I got mine at 1.1 I am good with battery vs power consumption
