set cpu

uhm. not sure if its working or not to underclock for screen off profile
do we need a custom kernel?

I tried it as i bought it when I had a g1 and the sliders are grayed out.. guess we have to wait for a kernel. Shouldn't be long though LG released the source already..

that's what I was thinking ... I bought setcpu when I had my mt4g
ugh I can't waot til we can reallt have control over our dual core!

I was able to use setcpu without an issue for screen off. Are you sure you guys gave root permission?

yep... I have profiles set.
but if u can't put scaling on demand then how is it working.
sent from my G2X with no regrets

Correct me if I'm wrong. All scaling does is how the CPU scales itself(to a given formula depending on the profile) for example if using a conservative scale the CPU scales itself by 15mhz depending on the task so if your min is 218 it would go up or down by 15 until it reaches the maximum or min. Since no kernals are available yet for our device it will use the default scaling profile built in. my screen off profile is a Max 218 Min 218 with a priority of 100. Regardless of the scaling profile selected I am forcing the CPU to down clock to that set of perimeters

thats how I have mine set up, but usually when I set up profiles woth notifications and I turn the screen I see it switch but I just realized as I'm typing that I only have one profile lol
so
your probably right and I'm lame for npt realizing tjat befpore I posted haha
regardless
thanx for ur replies and input

You are correct in that CPU scales itself based on the parameters Nvidia gave it. In this particular kernel there is only one governer by default (this is why you cannot alter the governor settings) and it's set to Performance Powersave. The scaling driver used according to the source code is tegra_cpufreq. I haven't dug far enough through the code to figure out what that means but it appears most frequencies are in intervals of 24mhz.

so i've been hesitant to use my setcpu. just wondering what everyone set their profiles to. lol

Overclock? Dualcore! WTF? lol its like ocing my mt4g to 2ghz... Cool to show off but really worth the risk? As well as side effects?

I only have one profile which is the screen off profile
Max : 218
Min : 218
Priority 100
thats all I have ever used, been getting really great battery went from 11am - 4am on a single charge and could of gone further but I needed to sleep

good to know! thanks.

I dont know why, but my SetCpu comes to the main screen and giving me option to what phone to choose.. then it Force Closes each time.
Cant seem to do anything...
Any help?

Are you positive your rooted?
Sent from my LG-P999 using XDA Premium App

Yes positive am rooted. I used and use titanium backup and terminal.
Does any One have the link to the free copy of the app on this site, maybe can try that before contacting the developer for support.

I would attempt three things before seeking any further escalation. First I would try running fix permissions using rom manager /cwm if that doesn't work delete the apk using root explorer and reinstall the software if that doesn't work create a nand backup of your device and start from scratch. Setcpu should work with the tegra2 plus the developer you reach out to regarding this will ask you to do this regardless.
Sent from my LG-P999 using XDA Premium App

Ok when you guys first start SetCpu (after clean install), what screen do you guys get? And what selection do you make?

When i first boot the phone I have a whole bunch of options to select on which device I use. The first one should be tegra2.

Overclocking

Hey guys will overclocking drain the battery quicker even with stock voltages?
Sent from my Nexus S using XDA Premium App

Different voltages are specified as stock for different frequencies. As the frequency changes, the voltage does too. Running 1200mhz with the stock 1000mhz voltage will probably cause instability and crashing.

Harrb, great post.

And if increase voltage, the power consumption should also increase.

i haven't played with voltages yet but in my experience the benefits of overclocking are minimal anyway, and they make nexus reboot often and other bad things :/

With the right settings you can get a fully stable and functional overclock, but it is on a per-phone basis due to varying quality of the same CPU during manufacture.

Currently I'm using icup kernel speedy 5 clocked at 1.4 and its been extremely stable. So what your saying is that the voltages automatically increase when I select a higher frequency, because I did not change them manually.

Open NSTools and select Voltage tab. That's the list of "stock" voltages for each frequency.

A CPU governor such as on demand, lulzactive and lazy tells the CPU what clock to be at and automatically change. While reading, it will be at 100 or 200mhz, while playing a game it will be at the maximum clock you tell it to. Saves power this way.

yes, usually 1 GHz is enough , UV or OC also may reduce hardware's physical life

SetCpu Files.

Ok so I want to start using setcpu because I have heard it helps save the heck out of your battery. Is there anyone with a killer battery saving set up backup file that I could maybe restore on my phone? Also if I'm using nstool for CPU settings should I stop if I'm using setcpu? Please though, if you have a killer battery profile, please upload it and share with the world! Thanks.

Setcpu and nstools work around the same way. Use nstools and lower your CPU clock speed to you desired amount where performance is balanced.

You use setCPU instead of NStools. The battery saving is in the screen off profiles. I have found that it doesn't help all that much on this phone. Just use SmartassV2 and you should be set

What's the best screen off profile?
Sent using Tapatalk, you know, the free version.

lowest safe cpu speed for screen off and in call?

trying to make some custom setcpu profiles and curious if anyone knows what the lowest safe cpu speed for when the screen is off and also while in a call and the screen is off?

Right now I'm on VI and I'm running 368 max and 245 min which is the lowest min for this rom. I always run the lowest on min and 1 higher for max on sleep settings. I don't encounter any issues.

Don't go below 200 when screen is off. You'll get the "sleep of death" at the most inconvenient times.

OP, you may want to look into andrev_oc or virtuous oc daemon. Both are superior to setcpu profiles.

I have already gone under 200mhz for sleep frequencies. Android revolution goes under 200 and I would run it under 200 always till now that I'm on VI.

I run lowest at 187MHz @ 700mV without any problem. I also set my screen off freq to that. Never tried one below that freq.

Here's a little info on using an overclocking daemon vs setcpu taken from the virtuous unity thread.
Introduction to the new Overclocking Daemon
This ROM features a completelynew wayof Overclocking and managing screen states.
The History But before explaining it further, let's talk about previous solutions. There are several different approaches to achieve "screen-state-scaling". That means basically thatthegovernor changes if you turn the screen off and changesbackto normal when turning the screen on.
This is mainly used to restrict the amount of CPU usage (the frequency in fact) during screen off. This can lead to a major battery life increase.
The solutions so far were:
Apps likeSetCPU,which changeautomaticallythe governor based on profiles Integrated solutions in the governor itself
Both these solutions have major problems.
The one with a tuner app is always a little laggy right after turning on the screen because SetCPU (or any other CPU tuner) needs some time to change the governors (up to 7 seconds). This leads mostly to major lag in the lockscreen.
The second solution is the smartass governor. It has already a screen-state-scalingincluded,so it reduces the frequency when the screen turn off. This could be a really nice solution but it has some problems too. Smartass most of the time is not really stable and has problems with its frequency scaling.
Be aware that the daemon only works if all CPU tuner apps are deinstalled. Otherwise it deactivates itself.

Thats very low. Surprised you do not get any issues.

Wish I could find the thread, but I was on a custom ROM that set the minimum CPU frequency to something below 200 by default, and I couldn't send text or MMS messages. Really weird.

System Tuner CPU governor question.

So I have been successful in using system tuner to set my CPU speeds and have them stick after reboot/shutdown. However my governor always falls back to on demand instead of my last selection. Is there any way to get this to stick?
Currently setting the startup as init.d. running synergy with their custom kernal.
Thank you!

Im in a similar pinch. If I want to make the on-demand governor remain permanent vs. the performance governor how can I make that happen?

You do have the "Set at boot" option ticked correct?
If that's not working you may need to use setCPU to do the "basics" for you and have System Tuner just do the rest. Here's a link to a free copy for XDA Members, http://forum.xda-developers.com/showthread.php?t=505419
