SetCPU and screen not turning on...

Now I am not blaming the app I am just wondering... everynow and then, when I wake my phone up, it doesn't want to wake up or when I turn it on and try to unlock it freezes... was wondering if anyone else was getting the same thing.

Screen off setting is min 400 max 400.

SetCPU issues
I have been having the same issues myself. Mine was set low to 100min/max: screen off just as a test today and it did that to me a on a few seperate occasions. Not sure why, just ended up battery pulling after 10-15 seconds of no response from the phone.

The cpu is set too low on screen off, go for 245 or so

setcpu does not play nice with r phones. i had problems witth it on every kernal i played with. right now im using the mix up kernal. i used setcpu to 1.2ghz max and 100mhz min. conservative governore. i have yet to find a set up to use while the screen is locked with no issues. what i do know is galaxy s phones only like the conservative setting. maybe a 400mhz max 100mhz min with conservastive governore would work?

Make sure setcpu is set to conservative. I set my lowest to 200mhz and max at 1200. No issues here other than sometimes the notification pull down bar is laggy but it does that stock anyway.

I'll try out those settings tomorrow. Thanks guys =)

Any1 know how to get to 1.4 ghz? my max is 1.2 on setCPU and i have voodoo kernel flashed

There's a kernal that allows you to hit 1.4ghz its the overclocked one from baked snacks

The rom don't control the cpu speeds. The kernal does. You cab run any rom kernal combo you would like. In order to hit the 1.4ghz you want you need to run a kernal that is capable of doing so

Is SetCPU really necessary anymore? If you run a kernel that's not locked into performance mode it will scale on it's own even without SetCPU. I haven't installed it on my Epic yet and when monitoring the phone with SystemPanel I see my CPU go down to 200mhz when idle and scale up when processes are running.

Where is the kernel for 1.4? I have baked snack rom max is 1.2 i know kernel is the part that "controlls" speed but I'm stuck. Any help

[Q]How to go under voltage?

I keep hearing people say they uv -xx number to save battery, how do you do that?

You can check the kernel thread you installed from. Usually use echo command and point to vdd_table. If you don't understand what undervolting is, you may not want to do it. It can cause issues if you undervolt too much. It can save battery life, but i would suggest using setcpu, you can find a free copy on xda, and setting profiles, like screen off, in call, etc., to lower values. I would say, stay above 300MHz for min. and clock down the max. Min are: 384-540 for screen off; 384-540 for in call. also, with some roms, you can set the main value, on the first tab, to a lower figure in the max column. I don't charge my phone everyday anymore.

Thanks for the detailed info. But I heard there's an app that does uv?

But... you need to have Bullet, Juggs or Faux's kernel for this to be useable

Luckily, I do use Juggernaut.

I installed fauxclock but I don't see a way to under voltage? I only see the interface to set CPU clock. Am I missing something here?

Ah ha!!! I see!!! Thanks!!
I've used up my "thanks" for today but I'll definitely come back tomorrow.

What is the uv number I should generally set to save battery but not have the phone freeze?
If I set it to negative too much and the phone freezes, I just reboot the phone and re-set the number to a higher (less uv) value?

it's different from phone to phone, you just gotta try it out and see.. i UV mine about 100mv under stock at 1.51ghz

Mine can do 100 also

I can only go -62.5. Anything over that will freeze the phone...

How come every phone is different in this regard, does this mean my phone is "born" to consume more battery?

Thought I saw posted somewhere here not to use SetCpu on our phone? FauxClock always FC's on me. Running Jugs overclock on rooted/flashed T-Mo SGS2.

Overclocking/Undervolting Not Working

I've been trying to UV my phone to save some battery. I generally keep:
Max: 1080 MHz
Min: 384 MHz
smartass or on demand
However every time I reopen SetCPU it's actually at:
Max: 1080 MHz
Min: 1080 MHz
The governor is sometimes what I save it as...sometimes something else.
I'm currently on Juggernaut (Bullet kernel) but The same problem occurred on Bombadier (Synergy kernel) also.
Any help please?
*Edit
I used to have an SGS Vibrant but never had this sort of problem so I'm a bit confused

Don't use SetCpu. Use the Faux clock listed in the juggernaut thread. It does a great job both with clock speeds and undervolting.
Still have about 20% left after 17hours using 384-1512 lagfree with 384-384 offscreen and -25mv

i ran into this issue and discovered that busybox was no installed properly thus causing this problem.
grab from the market "busybox installer" and make sure you have it installed properly.

Did this, just rebooted. Fingers crossed.

[Q] set cpu

Just bought it but I don't really get it. Both the max and the min. Are at 1.5 set on on demand but at the top it says 384 mhz (I'm guessing that's the current clock speed since I'm not doing anything) don't know which one to trust. should I set the min. at 384 ?
Sent from my SGH-T989 using XDA App

Set the min at 384 and the max where ever you want. Stock is 1.5. You can underclock or overclock (if your kernel supports it). If you overclock dont check set on boot til you have played around with your phone and are sure that your phone can handle it. You can choose what ever governor works best for you. Conservative is best for battery, performance is the worst. Most people go with on demand, but your results may vary.

I've found that the smartassv2 governor gets me the best results.
But its very unstable and can cause crashes.

thanks man i just dont know why it doesnt say 1.5 at the top since both the max. and the min. are at 1.5 maybe its a bug or something or maybe thats how it is
ps i hit the thanks

Try clearing the data on set CPU and then uninstalling and re -installing. If that doesn't work, but into recovery and wipe data and wipe dalvik .

Or if that doesn't work go into your superuser app and hit menu, then preferences and update your superuser binaries. Sometimes if they are out of date it can cause issues with set CPU.

[Q] Voltage settings

Just curious to see what voltage settings people were using in conjunction with joker's kernel. Screen shots? Post? Whatever. I'm interested!

I'm -50 undervolt a running good. No random reboots or anything. Even played Dead Trigger for an hour and all good. I am also running at 1.62 overclock. All is good.

Running 25 under and still good. I'll probably overclock it to get better performance.

I assume you are -50 on just the highest clock setting?

No -50 on all clock speeds. I use faux123 from the market. I was running -25 then just bumped it down some more. Might try -75 soon.
