How would i go about changing the cpu speed tht the rom has set it at. Like if cyan's rom is at 528 n i want max to be 328...how would i do tht ? wht file to mod ?
Instead of touching mods, better off using either SetCPU or the Open Overclocker widget, both available on the market or here. Just run a search.
The open overclocker widget in the market is fantastic. On cupcake I have mine set to 128-384 and set to 128 constant when the screen is turned off to conserve power.
Not just to hijack the thread, but AdrianK, at those settings do you find wake up too slow? For example when you get a phone call? I used to do the same as you, now I have it as 245 constant when screen is off and 384-528 when on.
Hey guys i appreciate ur replies but i wanted a way to implement it in the rom itself so i dont have to run a widget...thnx though..
SetCPU isn't a widget, its an app that you only need to run once and that's it. However I'm not sure if SetCPU also allows you to set the screen off frequency though which saves you even more battery life.
As for editing the ROM yourself to set the CPU speed, I can't help you there I'm afraid. Not sure if it has been posted on the forum or not too but try a search.

Yes, SetCPU will allow you to have a screen off profile so you can set the speed while the screen is off, and when it is on. It does need to run in the background tho I think...

yes i searched first
Ive heard that hero beta 4 works best with overclock at 528.
I have open overclock app and it enables me to set min and max frequency, which i dont fully understand the logistics of just that it pushes the hardware to function faster (maybe not?). How do i achieve 528? What do i set min and max on, thanks?
A general overview of overclock would be nice too, like when what settings are appropriate. thanks again
So I'm new to phone hacking, but an experienced software developer with a pretty strong Linux background... Anyway, I was rooting around the filesystem and found /sys/devices/system/cpu/cpu0/cpufreq/
I checked the values in scaling_max_freq and scaling_min_freq and they were both set to 528000. After doing some forum searching I see that some people mention using setCPU to let their CPU throttle down to 245 MHz when the screen is off, but when I tried to do echo 245000 > scaling_min_freq it doesn't ever change from 528000
I'm using Fresh 1.1, do I need to install a different kernel if I want my CPU to scale, and why can't I edit this file manually? I assumed that all setCPU was doing was editing /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and scaling_max_freq and scaling_min_freq

I dont know alot about linux or the kernel stuff but I do know that those of us that have been using SetCPU to adjust freqency have been installing a seperate kernel. Its Gumbo Kernel. Ill get you a link.

Looks like there's a script in there that fiddles with the memory freer and sets the scaling_governor to performance instead of ondemand or msm7k.
Changes /sys/module/lowmemorykiller/parameters/minfree 1536,2048,4096,5120,5632,6144
to 1536,3072,4096,21000,23000,25000 that's interesting.
edit: I'm not sure how useful that really is. Memory that isn't storing anything isn't doing anything, and so while it might make you feel better to say "Look! I have 90 mb free!" that really isn't as great as you'd think. If you run low on memory (ie the active process is needing more), then it's already going to kill and free up empty apps and content providers with no clients attached, so not really sure how useful that particular part really is.
edit2: So returning to my original question. If I want to change how low my CPU will scale down to, I need to install a new kernel?

Yes. Try the gumbo kernel. try scaling it to 160 just for fun. You'll see how slow it is, and it will prove that the cpu scaling works. try it at 528 also.
Hi all, I'm AWOL from the EVO forum while I get my wife's Hero set up.
I just loaded up DC 2.09 (latest / final release) and I'm working through SetCPU, but I saw one user at least who said DC automatically scales the CPU all by itself. So do I need SetCPU to get some battery benefits? The phone is screen-off a lot, mostly used for just calls, texts, and camera other than that, so if it will kick down to 245 automatically, that should save a lot of watts.
So do I need SetCPU, or will DC underclock out-of-the-box?
(Edit: I guess SetCPU gives me the OVERclock, doesn't it? Still, I'd like to know about DC's background so I know how to set up profiles, or even if I should.)
I haven't used DC in a while, but I'm fairly certain it doesn't come with the ability to underclock by default....I'm pretty sure it comes with a stock or very-similar-to-stock kernel that wouldn't have any different cpu speed settings. I could be wrong but nothing in the main OP of his post (here: http://forum.xda-developers.com/showthread.php?t=656690) suggests otherwise. That ability might be available in the DConfig settings somewhere, but I haven't used/seen it in a couple months to remember. Check there first.
If you don't see anything, you probably will want to use SetCPU or the OC widget to scale down. I'd also recommend using the Screen Off profile in SetCPU, to lower the max speed when the screen is off. Sounds like it would be a useful one for you.
This may not work with the included kernel, so if you don't see any results try a different kernel built specifically for use with OC/setcpu:
This one: http://forum.xda-developers.com/showthread.php?t=750170
or one of these: http://forum.xda-developers.com/showthread.php?t=705074 for DC.
Hope this helps.
I searched but couldnt find a clear answer. Is there any reason my set cpu only goes up to 998 max?
That's the native clock speed of the CPU? I don't get your point
SetCPU isn't an over-clocking app, you want a higher speed, you have to flash a kernel that supports the speed you want.
I figured out my problem..I was running a sense rom on my G2 which let me overclock. Its been a while just got my nexus repaired and back from htc i just need a custom rom to overclock..sorry guys
Hello all, today I will be showing you how to speed up your Nook Color a bit... these methods should work for CM9/CM10/CM10.1/Paranoid Android/etc., but I personally found these out while running PA ICS. The apps you may need to make your phone faster are Ram Manager (Free OR Pro) and No Frills CPU Control (In the case that your ROM doesn't have overclocking in settings). Basically, using these "tweaks" (minus overclock, as whenever I flash a ROM the first thing I do is overclock it), I went from a painfully slow (as in, I was ready to go back to Gingerbread) device to a somewhat faster device. I've seen huge differences in launching games and apps especially, and opening to app drawer seems to be smoother also.
CPU Overclock
Either using No Frills CPU Control or the built-in overclock, set your max CPU speed to the highest on the list (not exceeding 1200, but it shouldn't show anything above that anyhow). Change your governor to either Ondemand or Performance (I personally use Ondemand and have no problems with it). Most of you are probably already overclocked though, so please don't look at me like I'm stupid.
Swap Space
Open up RAM Manager and there should be an option to change your swap space at the bottom. I changed mine to about 48 and am content with that, although I must add it may make your SD card's life shorter. This will increase your RAM, thus allowing you to have more apps open at once.
Force GPU rendering
Open Developer Options in your settings app and check "Force GPU Rendering"... I'm guessing this is one of the biggest factors to my tablet becoming smoother, as from research it helps lower end devices achieve a better framerate, although it may decrease your battery life. Also, I cannot guarantee every app will run great with this. I tested a game (Dynamite Jack) with this setting enabled and it wasn't too shabby at all! But yes, I can definitely see a difference in the overall speed of my Nook Color.
Please tell me how these work for you
I tried these settings, but unfortunately didn't perceive any performance improvement.
Good call on RAM manager. Hadn't seen that before, its going on my NC and RAZR now
Can anyone tell me a good reason for that RAM Manager app to have the permissions it does? Location, Identity, and full network access?
Does NOT work. All this app " no frills CPU" does is provide a GUI front end for the settings already found for our nook color using CM 10+ in its "performace" settings. Also this app does not provide over clocking above our set 1100 MHz. You will need a custom over clocking kernel for the encore for this. Check over on the CM 10 kernel thread n the development section.
