SetCpu Settings?

Mine is
Performance
Min/Max 1.2 ghz
Auto dectect
Whats yours?

Really auto detect? After every kernel dev says that auto detect isn't stable?
Really?

what should i put?

you have to use auto-detect for setcpu to detect your availble clock speeds
on-demand is BROKEN
performance will drain your battery abnormally
running at 100 min / whatever max on conservative is the most stable option for this device at the current time

Leave the advanced settings alone also?

not to contradict, but you dont have to use it, you can use the setCPU.txt file and i recommend it
here is the one i use currently with the D02 1250LV kernel, it is nothing more than a simple text file which tells the setCPU app what are valid steppings/scaling so it cannot auto-detect incorrectly as it often does
http://dl.dropbox.com/u/12311939/setcpu.txt
all you have to do is edit it to the steps that match the kernel you load and drop it in the root of the sd card, then go into setCPU, hit softmenu to go to device selection, scroll down and choose custom or manual...i forget what its called...then scroll down to the bottom and tell it to use the setcpu.txt file option and restart....done, no more problems at boot with setCPU
I only use performance when benchmarking. I use on-demand day to day. Set to 1250 max 100 min. I actually read the entire setCPU dev page, I suggest you do also, keeping in mind the limitations of the kernel you choose to load. I do not use on-demand scaling. I do not use profiles either. I do however, after testing my own device, use "set at boot". Two things on that. 1. setCPU now has a safe mode feature to get out of a problem and 2. I also use the setcpu.txt option instead of auto-detect which is hit or miss. Using the setcpu.txt file method (be sure to go to device selection and choose the bottom custom option) setCPU cannot accidentally set itself to the wrong frequency, it gets it's allowed steppings from the file you create.
if you read the setCPU dev page you (not directed at you jt ) will learn all of this and also about the advanced settings....but they work fine as they are for my device/kernel/usage

Nice find there james
Im wondering what would happen if you didnt match the increments in your txt file to the kernels native ones?

Lol, I only speak of what I know to be true you guys have far more knowledge but I tested this on my own device and also used it on the ally I had so I know its good

Id say probably either fc or nothing. Either it would try to hit something it cant and fc or it would discard the step, but then the large jump sau from 200 to 600 skipping 400 may cause an issue

Well, if I can keep mine running stable for a couple of days, with no "permasleeps" then I will give start on boot a try. So far I'm having excellent luck with 1100 max 100 min with conservative. Set to auto, it brought the right figures up immediately. So far the thing is really running great with the 1100 LV kernal and the settings I mentioned above. I'm sure my quadrant will be lower than 1200, but for some reason the 1200 kernal was only stable when I was placing load on the device, actually using it. When it was idle the screen would "permasleep". Very odd. Stress testing on the 1200 LV kernal threw no errors, but I still had idle issues.

Sorry if it is a noob question but
I have the jt's voodoo kernel and just restored my setcpu from the titanium back up...
the max that it gives me is only 1000000....
I thought It should change to 1200000
how can I change it?
if not what should I do to OC this bad boy?
btw I Used the recommended speed...
Thanks

Download the 1200 w/ boot animation. This happened to me last night when updating my wife's fascinate. I first downloaded the one without boot animation, which was fine, but only would clock to 1000 and was getting the battery not connected error. So I flashed the 1200 w/boot animation and fixed everything.

Think about it for a second... Has it sunk in yet? Didn't think so.
You changed speeds so you need to redetect your speed. Either do that or uninstall the app and reinstall it.

Set CPU Not Functioning

So, I guess I'll just C+P my post from the SetCPU thread since no one was able to answer the question there. I figure I might get some help from the EVO crowd since this might be specific to the device.
'So I have a wee bit of an issue with 2.0.4 I think... I just rooted my EVO 4G, installed SetCPU, AutoDetect, main Profile 768/460 set on boot. However, I rebooted and it says in the Notification bar that that's the profile it's running, however when I open up SetCPU the speeds jump between 245 and 998...Is SetCPU not throtleing the CPU correctly?'
Also, the only options for SetCPU I'm getting are userspace, ondemand and performance.
Is there something I did wrong when I rooted it?

What kernel are you using? The reason I ask is because I had the king #12 installed and setcpu didn't seem to be doing anything. Based on the the scaling options it sounds like a Toast kernel. Different kernels get different options. King kernels have about 5 different scaling options. I think for $29.95 he will add a 6th option.

Stock kernel. I haven't gotten around to messing with the kernel or ROM yet. Do I have to be running a modded kernel for SetCPU to function at all?

Well this is very simple then you can't OC the stock kernel. I also don't think that SetCPU can govern a stock kernel. You must flash either Toast or Kings..

SetCPU will govern a stock ROM, just hit menu on its main screen and select Disable Perflock. Disable the perflock and tell it to do so on boot. Then you can change the clock speeds around and profiles will work. Only downside is it still won't overclock, but if you are looking for power savings, this is the way to do it.

Ya I didn't think you could use setcpu with a stock kernel so that's some good info right there.. thanks.

Thanks! That did it! I wasn't really liking the idea of flashing a custom ROM or kernel to my device just yet, so this is great. I had my fair share of issues with HD2 running custom ROMS and kernels and for now I want something that just works until I get more familiar with the process.

[Q] setcpu not working

I am using an hd2, and i have noticed something that may be causing a lot of battery drain, that is consistent among every build that I have used. When I use setcpu, and give it root access, and whether i select auto detect or manually put in nexus one/snap dragon, it does not listen to the cpu cap that i put. i will exit the app, and go back to it, and the cpu clock speed with almost always exceed the cpu cap that i set, and many times, it will be running at the full 998 mhz. why is this, and how can i fix it?

I uninstalled SetCPU the other day as a little experiment. It makes f-all difference to me. In fact it makes things worse.

no longer needed with the latest kernels

This problem seems to relate to a kernel feature called perflock .. disabling this in-kernel allows the cpu cap in setcpu to be adhered to .. Unfortunately this is done at compile time and has no userland interface to use. I dont think its relating to all the battery drain you see but for sure if you limit cpu speeds with profiles like screen off it will have an effect.

try updateing super user libraries.

Whats that then ?

how would i go about updating the su libraries? does anybody have an actual fix to this, because i would think my battery would be a lot better if the set cpu app was actaully working. and no, the latest kernels dont seem to be doing their job, because they all burn through juice like theres no tomorrow.

u have 2.04 installed ? it fc'd for me , now im using 2.02 no problems , try that

You don't update the su libraries .. su is either a static file or a link to busybox .. i cba looking right now .. probably a binary compiled statically ..
To have your issue resolved have a word with your friendly neighborhood kernel builder and ask him to disable perflock .. Its not needed for normal operation.

I'm having the same problem. Does anyone know how to get setcpu to work?! I have an HD2 running darkstone Froyo.

[Q] cpufreq parameters without using 3rd party apps

Hello.
I've got a stock Android 3.2.1 (A501 4.066.29 COM GEN1) rooted with Stock/HV/Taboonay V3.7 for HC 3.2 16-10 - 1.64Ghz/UV control kernel.
The question is:
how to set cpufreq parameters (governor, max_freq,..) WITHOUT using 3rd party apps so that the parameters were restored after reboot.
Thank you for reading this.

Either the kernel needs to support init.d scripts or a service needs to execute on boot.
That kernel doesn't support init.d and Voltage Control has a startup service.

Forgive my ignorance but I can't put to use your answer.
I don't get where is Voltage Control and what I have to do.

Get Voltage Control from the market, make adjustments, save as boot. You'll be given the option to save as init.d script or startup service.

Well.. I tested it. Odd app.
First of all it can see only one core. It's funny. After reboot cpu0 works in conservative mode, max_freq 1.4 GHz and cpu1 in ondemand mode, 1.0 GHz.
I tried to edit init.d script and add the 2nd core but after reboot cpu worked with the default kernel values - script didn't work at all.
Moreover Voltage Control shows voltages turned upside down - the less cpu frequency the bigger voltage values. I fear to use this app

Download setcpu or antutu cpu master it recognizes dualcore , has the boot option

More education would be advised To you PLEASE DONT BREAK YOUR TABLET
Please do not take this the wrong way..
it does sound like you do not know what your doing.. I suggest you read more about over clocking./under voltage of a TEGRA 2 DEVICE.. That will get you more understanding about what you need to do. And maybe even help you decide if you really want to do this or not.. There is alot of resources online about this subject. I have tried custom kernel with set cpu.. I use it on my 650 mhz phone. clock it to 768. but it has a huge battry issue when running at that speed.Not to mention It would be dangerous to leave it on my purse with something running might be a fire bug.. GOOD LUCK .

Basically lower voltage at higher frequencies keeps the CPU stable. Leaving it linear would increase temperature exponentially.
Script Manager can run scripts on startup but I don't know how you could disable them if they keep it from starting up.
I didn't know about VC and dual core though. My bad.

I don't understand? You want something that does the same thing but you don't want to know it's there?
I found one app called System Tuner that lets you adjust CPU frequencies individually. I don't know why though.

Actually I don't like how these apps work. And I thought that setting up a few parameters would't be difficult. It seems I was wrong.

Yep. Code has to execute to do stuff, otherwise that stuff doesn't get done.

System Tuner Pro allows voltage adjustments on overclock settings. If you're interested. Also, has a lot of packages integrated into one (task manager, app freezer, etc). They have a free version in the Market if you're interested. It's nice to have several apps, in one nice package.

It's because the 3.7 kernel you used, is really not compatible with the a501. The ultra-low voltage causes "screen freeze" and the "sleep of death" when under 3g only. It's a known issue with the 501 and 3.6 and 3.7 kernels also. I would reccommend RTrips 3.4+. Probably his best for for a501.
I ship it with my own Alexandra II and III rom. No issues with it, and none ever reported.
Had I noticed when I woke this morning, you had an a501, I could have given this advice. Sorry, didn't have enough coffee

The problem, is that a lot of dev's, don't have a501's, only a500's. So they really can't test a lot on it. And sometimes, the issue doesn't happen for 2 or 3 days. Sometimes less. I'm going to experiment a little this weekend, with some of the newer kernels, and mess with the voltage's and see if I can get it stabilized where it doesn't freeze on 3g only.

Moscow Desire ,
Thanks for clearing it up and the advise. I'll try either 3.4 kernel or your ROM.

If you go to RichardTrips kernel thread, you will see a link to his older kernels.
You will find the 3.4 listed on his server. I think you just need to flash it, although I usually dump Dalvak cache.
Alex II is an easy install. Alex III (3.2.1) is a little more ... interesting to install, but not difficult. If you run into an issue, post it in my thread. Everybody else has got it installed, so I think you'll have no issues either.
It's the only "certified" 3.2.1 for the Acer a501 that I know if. Not that the other roms are bad, because they really are good, but, the 3.2.1 they advertise, are from system dumps after running an update, or adding missing files to a 500 rom. The TMPL is an Acer release.

[Q] Change Default CPU Speed On Boot Permanently - CM7

Like the title says, I was just wondering if there was a way to change the default CPU speed on boot permanently? I know I can use SetCPU, but sometimes that hasn't held through a boot and I had to set the speed manually. So, I was hoping there was just some script somewhere I would have to change. But then I got to wondering, would that be possible from my phone? Would I have to build my own kernel? Or would I just be able to decompile the rom in dsixda's kitchen to change a kernel script? Any help is greatly appreciated!

I use ROM Toolbox. It has a ton of stuff including CPU Control and CPU Profiles (like to make it 691MHz max when the screen is off). And you get a lot of other stuff with ROM Toolbox. But you could say the CPU part is like Set CPU. Don't really know if this answered your question. Hope I helped though.

I'm pretty sure CM7 has a built in CPU setting feature in its Cyanogenmod Settings -> Performance menu. It gives you the option to set on boot as well. I've never played around with it so I'm not sure if it'll give you the same problems you're describing now, but it's worth a shot if you don't want the separate app.

Is your phone rooted?
