[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] CamFlawless:
Be sure that you have it selected to apply on on boot. While it should save your desired settings, they won't be applied after a reboot unless you have specified it to. You can also choose when after a reboot it is applied (whether it be immediately, 5 second delay, etc.)

Performance governor is not an option.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] RobbieL811:
What kernel are you using?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] CamFlawless:
I would assume KT747 seeing as he is in this thread.

I have zero complaints with my setup, which is Ktoonservative/Noop. I get easily 3.5 hours screen time and haven't experienced any lack of performance. However, every device handles each governor and i/o scheduler differently, so your best bet is to test a few and see what gives you the best results for your device and own personal needs.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] RobbieL811:
Lol. Good point...I also use Ktoonservative/Noop normally. I am currently trying out a few others. I also like the zen scheduler. I'm also using liltitiz voltages from page 2 of this thread.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DarthDerron:
From what I heard OnDemand governor is supposed to be good for battery life. Again, differs from every device but you may want to try that.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Heisenberg420:
Pretty similar to noop but io schedulers can only make so much of a difference :p
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mw86:
I was finding Zen good but isn't free of issue as the onky one i found was it can get stuttery on long term i/o transfers like prioritizing foreground process is causing slow down when backround important tasks are not finishing fast enough to support the foreground task enough under a fully utilized i/o state. Under less utilization like everday light use it likely will save juice due to it being of the Simple Scheduler family known to be good for solid state storage like our phones storage.

Using ROW which i need to find info on i clearly see the best read and write rates i have and repeatable consistent results. It may have to do with an algorithm much like ram is accessed in a matrix. Atleast thats what the tunables for ROW remind me of.

Edit: i found this info after search. ROW is similar to Zen that read is prioritized over write but Zen uses foreground and backround to decifer priority where ROW attempts to take on any read requedt made but filter in writes before they cause too much latency. All i/o have their uses and none are superior to all others especially since everyone is looking for a different feel or use of changing from default i/o.

http://permalink.gmane.org/gmane.linux.ports.arm.msm/2911

*the following is the info posted at the link.

ROW scheduling algorithm will be used in mobile devices as default

block layer IO scheduling algorithm. ROW stands for "READ Over WRITE"

which is the main requests dispatch policy of this algorithm.

The ROW IO scheduler was developed with the mobile devices needs in

mind. In mobile devices we favor user experience upon everything else,

thus we want to give READ IO requests as much priority as possible.

In mobile devices we won’t have AS much parallel threads as on desktops.

Usually it’s a single thread or at most 2 simultaneous working threads

for read & write. Favoring READ requests over WRITEs decreases the READ

latency greatly.

The main idea of the ROW scheduling policy is:

If there are READ requests in pipe - dispatch them but don't starve

the WRITE requests too much.

Bellow you’ll find a small comparison of ROW to existing schedulers.

The test that was run for these measurements is parallel lmdd read and write.

The tests were performed on:

kernel version: 3.4

Underline device driver: mmc

Host controller: msm-sdcc

Card:standard emmc NAND flash

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mw86:
Thats the latest Ktweaker version. If you mean to have the two additional i/o schedulers this is on and only for AOSP 4.2.1 Android version like CM10.1. This mentioned kernel update was posted by Ktoonsez around the 20th. I have a feeling row and zen will be added to the touchwiz and other aosp rom kernel next update ie for android 4.1.1 and 4.1.2. If your not on CM10.1 or similar you have the latest kernel version most likely.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mw86:
Well that reboot could of been from the undervolt. Or you reached shutdown temp of your cpu and since it was a game the gpu was adding plenty heat so in any case likely your max speed mad it hit shutdown temp or the lack of volts as temps rised caused it. As temps go higher the voltage requirements raise too.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Heisenberg420:
Too much undervolting can cause any number of problems. That could be your problem. I've never heard of simple io schedulers like sio and noop causing stability problems. Don't worry too much if your phone can't uv. The main benefit is reducing heat which reduces unnecessary battery drain. Start with -50 maybe -75 all steps.

Also I like ondemand on touchwiz Roms. Ktoonservative I find better on aosp Roms. Personal preference I guess. If you do choose ktoonservative make sure you delete gsiff_daemon and qosmgr from /system/bin.

Well let me rephrase; it's actually an issue with the ktweaker app...

I'm running stock rooted 4.1.1 touchwiz with the touchwiz kernel. Noop scheduler and ktoonservative gov. Almost every time I start the ktweaker app to check on things, the "your saved governor settings do not match current governor settings" warning appears. Whether or not I reapply from tthe popup, the general settings still show the ktoonservative governor in play when I check it out.

Any thoughts???
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] procco13:
Not that it helps your situation but I have a similar problem with my min/max frequencies. I set my max to 1512 and each time I open ktweaker it says my current settings don't match my saved settings. It appears the settings don't stick when exiting the app.

I'm on stock touchwiz with ondemand/cfq.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kofrad:
I had the same issue as both of you. Certain settings would refuse to stick. It hasn't happened in a few days over here and I'm not sure what remedied it - but it's gone.

My first thought is a conflict between two apps trying to set the governor and such. TouchWiz doesn't include any UI to set CPU speed that I know of so I wonder if it messes around in there on its own..
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Swiftks:
Clear app data & uninstall ktweaker. Then reinstall kernel, making sure to wipe caches before and after install. Should be fine after that.

Check to make sure that power saving mode is off, otherwise Touchwiz will try to modify your max/min.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] baconatorXVI:
Just dropping in to say I've been fighting this issue across many aosp based roms for the last few months. I'm going to try swift's fix next time I encounter this issue, for me it would happen during screen off when I would watch my frequencies using cool tool. Oh and of course I didn't have any CPU screwing up apps installed.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mw86:
Hello two solutions to two different inquiry.

Min max if not power saving mode on and no other app setting min max its likely because some roms have script in initd folder of system/etc/initd for example Freezas script nithing wrong with it but it will override what you try to set. If you have a script there with name like 70tweaks cant remember... delete or move to another folder as a backup.

Governor settings not applied

Well if not in powersaving mode and not using other apps that are effecting it i would say try the following.

Find an app that sets governor not ktweaker. My example will be Rom Toolbox.. Now set everything in ktweaker go through all menus multiple ytimes be sure all is correct. Have set at boot immediately. Now make a backup in ktweaker. Go to rom toolbox and slide menu to the right one. Click kernel settings. Scroll top heading over to governor. Make sure what you set is exactly what is displayed. Now check apply at boot on top right. Hit back till on home screen, reboot. Wait till ktweaker says settings applied. Then wait longer about 5-10 more seconds rom toolbox says it was granted super user. You may see rom toolbox while ktweaker is applying stuff but still wait till ktweaker says its done and then more time till you see rom toolbox message. More than 50% of the time it solves this. Enter ktweaker and hope that it says no such message. The idea behind it is ktweaker applies all but something in system gets in way of one or two of the governor tunables being applied and the second app fixes the one or two that got reset in a automated way.

I've tried everything to get frequency settings to stick and absolutely nothing works. It persists across all Roms. I think we just have to live with it. Sometimes I'll set it in the ktweaker and hit back to get out of the app and then I re open the app and it already wants to reset the frequencies...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Swiftks:
Stupid question, but you have lock frequencies checked right?

Also, I'd try going into Tibackup, clear data of ktweaker, then uninstall. Go to /system/etc/int, and remove the two .sh scripts the kernel puts in there. Reboot to recovery, wipe both caches, install kernel, wipe caches again, fix permissions, reboot. Go back into ktweaker and redo your settings from scratch... DO NOT restore your settings from a saved file, but totally redo them. Report back.

Delete .sh scripts in system/etc/init

Uninstall KTweaker through Titanium Backup

Reboot Recovery

Reflash Kernel

Wipe Cache/Dalvik

Fix Permissions

Its a 4.2 thing. Ktoonsez explains it in his thread
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mw86:
If on 4.1.1/4.1.2 just renaming the app is enough and the reason its necessary is only if you use Ktoonservative or a governor with hotplug built in. Disabling mpdecision keeps second core from turning on unless the governor said to. Otherwise mpdecision will enable and disable it anytime it is programmed to.

For 4.2.1. rename the file but futher more you need to edit you postboot.sh to prevent the system from having logcat errors over and over from disabling it. So folliw here where i posted how to stop mpdecision on 4.2.1 if one of you are on that. http://xdaforums.com/showthread.php?p=35102460
