Overclocking/Undervolting Not Working - T-Mobile Samsung Galaxy S II SGH-T989

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.

I searched "Faux" in that thread and couldn't find anything. Am I missing something?
*just kidding, found the link in the changelog. giving it a shot. Thanks a lot!!!!

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.
Rooted using the one-click method.
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
Try this to hit 1.4.

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] 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.

CPU apps

I'm having trouble finding a CPU app that works perfectly with this phone. I've tried setcpu, CPU master, system tuner, and nstools. What's everyone using to oc this thing?
Sent from my SGH-T989 using xda premium
Depends on which rom your running but in general...you should use none. Most roms already uv and oc and if u use an app it'll butt heads.

My issue is that it seems like my phone is skipping steps all over the place. I'm using cpuspy and the usage jumps between Max/min clocks. I'm kinda not digging that. Its the same with every rom i flash.

That's not an issue with your cpu app. It has to do with your governor (the thing that controls how your CPU scales). Most ROMs come with ondemand by default which pretty much does exactly that, which is jump from min to max as needed. If you want something that scales more, you should look at conservative (for better battery life) or lagfree/interactive (for better performance). Lagfree/interactive are only available on select kernels though (whereas conservative is almost universally available). Streamline definitely has them and I think synergy does too.
Also CPU apps don't butt heads with the ROM/kernel default settings, it just overrides the default settings.
Yea I figured that but this is the first phone I've had where on demand performs that way. I've had a nexus s, epic 4g, evo, and a g2 and they all scaled across the steps ondemand. Ondemand on this phone works like the min/max governor. But your right conservative scales across the steps well. Just a bit choppier. About to install nstools and mess with the threshholds and whatnot.

Cant UC phone...doesnt save

Im currently on JMT v9, and want to lower my max CPU to 1512Mhz. Ive tried using the included Voltage Control Lite...slide my max freq down to 1512, then hit apply changes. Ive also tried using AnTuTu CPU Master Free...again, slide max down to 1512 and hit Apply. Also set it to apply upon reboot, which I have done, and it goes back to 1728.
Any ideas?
Faux kernel? Download CPU spy. I'm on clones drones, although set CPU doesn't show the changed Max freq, CPU spy shows the phone never goes above what I've set. If that makes sense

Your thread title says under volt but it appears you want to underclock. Try system tuner or ROM toolbox.

Yes underclock my bad.
Tried system tuner, pulled the slider down to 1512 and it pops right back to 1728 lol

Well i just read in the jmt thread this may be an issue with the kernel...others can't set at 1510 either. 1458 works tho

[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.
