SetCPU and screen not turning on... - Epic 4G Q&A, Help & Troubleshooting

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.

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

SetCPU Issues

I'm having problems with the so called "sleep of death".
I make all my profiles and leave the defaults for conservative. Minimum is set to 200mhz and max for screen off is 600.
It seems like no matter what I set the clocks to my phone never wakes up from sleep. I have to pull the battery to turn it back on.
Running SFR1.1.1.

Edit
Is it the screen off profile?
If you're using the included kernel for SRF 1.1.1 don't use a screen off profile, set it to conservative, and minimum cpu at 200mhz. It should be fine with those settings.
Its on the first page of the SRF thread.

Switch to paid version of Voltage Control. It's optimized for us now.
Having issues with setcpu freezing up my phone even with no profiles.
If voltage control is optimized for epics I may buy it. Underclocking really boosts battery life.

What was your lowest freq set to? Some phones don't like 200 at all
Sent from my armed and operational battle station.
Wasn't Conservative deemed buggy for the Epic? And ondemand was the better option?
The new twilight kernel, which is included in SRF 1.1.1 is fine with conservative.
There is a free version of voltage control too. Uninstall set cpu and try that first and see how that works for you... if that doesn't help, maybe you should flash a different kernel.

Yup. I believe this is posted a few times on the ACS thread. Go with Genocide or Vision. Now on demand will drop below 200 even if its set at your minimum but may very well still work.

Someone correct me if I am wrong, but I thbought there were also problems by using profiles at all.
Have you tried getting rid of the profiles? (After backing them up, of course)
Sent from my SPH-D700 using XDA Premium App
I use the Vision kernel with SetCPU to ondemand with NO issues at all I had profiles enabled at one point but it seemed redundant because I had it set to ondemand. If you have it set to anything other than ondemand then I can see using profiles.

Undervolting, Overclocking and random freezes.

I'm running back into the problem of custom Roms freezing on me, no FC's, just the phone freezing and requiring a battery pull to re-boot. I odin EC05 plus, let it boot and sit for a few minutes, reboot, let it convert, flash cwm purple, wipe, then flash whatever rom, and eventualy they all freeze.
The only roms to never give me that problem is CM7, MIUI and true stock.
Tried everything, except for not using the stock cable, but even still, cm7 and miui have no problem.

I've had the same problem with SRF 1.2...and I linked the problem to certain SetCPU settings like on demand and userspace and to undervolting to much in the higher OC'd frequency ranges...even though I've experimented wih these settings and found a somewhat stable medium...I still get the random freezes once in a blue...I don't know what else it could be.

Right now I'm on SRF with the 1.1.1 Kernel, using setCPU 200-1000, cfq, and no undervolting at all. I was on the 1.1.0 Kernel using voltage control when I had it freeze. I've uninstalled voltage control and galaxy tuner. Oddly enough setcpu dosent fc when I go into the voltages, which it did a few flashes back.

What problems do you think Galaxy tuner was giving you...I'm using it right now?
Sent from my rooted, suited, & booted Epic 4G kno dat!
I wasn't sure, but I figured with using setcpu it would be best to uninstall it so there wasn't any sort of conflicts between the two.
Sent from my SPH-D700 using XDA App
I'm not sure I follow where the conflict btwn those 2 apps would be...once controls cpu speed, governing, and voltage...and the other controls screen brightness and sound attributes...not trynna be a smart ass I'm just trynna make the connection?

In galaxy tuner there is some options for overclocking, as well as IO scheduling.

You didn't read my OP, I have no problems at all with FC's, my problem is the phone freezes and I have to pull the battery to restart.

At any rate. Sounds like your phone is garbage. Make sure you enable journaling to help mend the fc's.

If you aren't undervolting and are having this issue on multiple ROMs, it sounds like a conflict between some apps like you suspected. That or something is not right with your phone. Freezes happen to me when undervolting too much but you aren't doing that....edit...maybe your phone just doesn't like the 200 minimum that well. If I remember right, stock values are 1000 max and 400 min.
Sent from my SPH-D700 using XDA Premium App
I'm wondering if maybe the 200mhz is whats doing it then, I always figured 200-1000 was stock, and the phone would only freeze when the screen was off. Right now I'm using setCPU with it set at 200-1000 with cfq IO scheduling. If I have more freezes I will try bumping up to 400-1000.

im currently undervolted with the aosp rom from dub with genocide's final kernel...200mhz is perfectly fine...if 200 is underclocked too low or other frequencies are too low...sod or freezes will happen with the frequency with the wrong voltage is reached..i have setcpu and voltage control together but mainly use the new setcpu...when idling, i see a 1 percent draw in 2 hours and 6 minutes...and use stability test whenever you underclock to see if it safe to use...just my 2 cents...

Synergy and SetCPU

Just wondering if anyone is running setcpu with Synergy and what there setting are. I have never used this app before and am having a hard time finding out how to use it. Any help will be greatly appreciated!
I have it and they say the best thing to do is leave the main screen alone but make one profile. "screen off" set it to the lowest on both maximum and the minimum, and the % to 100.

I didn't think it worked on 2.3 either, downloading now....
setcpu wont set the max on the synergy rom (RC2)
EDIT: fixed it.. you need to do perflock.. then you can set the max on synergy

[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.

Franco Kernel Updater Questions

I'm new to the Galaxy Nexus and I'm coming from an OG Evo that I was using SetCPU with....
I wanted to see if anyone could recommend settings for the Kernel Updater...I'm looking to keep the battery going as long as possible in between charges.
also, if I use this app then I don't need to use SetCPU, correct?
no you dont need set cpu.. everything u need is within that app.

I personally use 192 to ~1200 MHz. With SmartReflex on (disable it if you want to do custom UV).
Play around with Generic Hotplug. It may be good for you and it may not.
I have my governor set to ondemand (it was on interactive but Franco recently changed it back to ondemand as default)
TO EVERYONE WHO USES franco.kernel updater
Please be aware that the "Turn off Thermal Throttling" feature in the latest franco.kernel updater app actually Turns on Throttling down CPU frequency when it reaches more than 70 degree C.. So just remind it that it is Vice Versa
I use ondemand governor, 384 min 1420 Max. Battery life is quite gd for me
