I know that you can change the governor speed in the settings, and its set at minimum 216 and maximum at 1000. What is the risk of increasing the minimum to say over three or four hundred? At what point will it become unstable or crash? I know it is different for every kernel, I'm just looking for a good, safe setting. Thanks for any input.
Sent from my MB870 using Tapatalk
It won't crash from increasing the minimum speed, because there is no overclocking occurring. Increasing the minimum speed is safe; however, you will notice a decrease in battery life from increasing the minimum speed.
I tried to increase it, but it won't come off of 216. Do I have to change another setting to make it take?

You can't overclock it because our kernel doesn't support it. Nothing you can do will change it. The only way we'll ever be able to make use of those settings is if we get an unlocked bootloader. Then a custom kernel.

You must have done what 7 billion i7 3960x's would take 103,227,037,000,000,000,000,000,000,000,000,000,00 0,000,000,000,000,000,000,000,000,000 years to do, and accidentally cracked your bootloader and accidentally wrote and flashed a custom kernel, all without realizing it.
I don't appreciate the sarcasm. I never said I cracked anything, nor did I EVER say I unlocked a kernel that devs with a million times more ability than me could bot do. If I was able to accomplish such things, why would I even be on here asking for help? My phone does perform better with minimum set up, but I NEVER said it was like a new phone. I am a relative noob to this, and I know my limitations. So, if all you have is a smarta** comment, keep it your self.

Hello everyone, I just had one quick question (I'm also very new to Android in general so I don't want to do anything to make my phone un-useable). Does Setcpu work with samsung fascinate root and clockwork mod? I heard some people say theres a seperate application to underclock and overclock the fascinate, but then again i do not think they knew what they were talking about. Is there a better program than setcpu?
Sorry if this has already been posted. I know its been posted in other forums for different phones, but didn't find one for the fascinate.

SetCPU is the most popular one. You'll need root to even use SetCPU. And you'll need CWM to flash the OC Kernels. If you dont OC SetCPU is pointless
On that note.
SetCPU must be ran on conservative and with no profiles and no load on boot.
If you do reboot your phone, mine reverts back to 800, so I need to manually change it to 1200.
Do u have to set both min & Max to 1200???
no just the max

Yes, of course you are right. Actually the other day I forgot to slide sliders up from 800 to 1200 and I was getting really good battery life for like 2 hours my % only dropped 1% and I was like wow.
Im just pleased as punch that there are OC/UV kernels out, its the best of both worlds.
Actually my battery life is above average it seems; either that or my usage is below average so Im not draining it as much. I'd gladly mildly overvolt to something like 1350mV if it meant I'd be rock solid stable at say 1.4Ghz
BTW, jt I heard you might be getting out the kernel speed chase after these 1.2Ghz's? Just don't feel like chasing 1.3 or 1.4?
I am running Dirrk's D012 LV 1200 Kernel with SetCPU
Luckily, the LV runs EXTREMELY smooth on my phone..
So smooth, that for the past day now I have been able to run with "set on boot" and constant restarts on my phone..and with Profiles for Screen Off, Temp (probably wont get there), and Charging. I can say that I have had no problems with my profiles and set on boot. Then again, I don't want to contribute to hurting anyone's phone
Just thought I'd let everyone know how my phone (and potentially others) can seem to handle profiles and set on boot.

I was hoping to get some help. I have installed jt's 1200 voodoo kernal, and I can't seem to get Setcpu to clock at 1200. It still says that the max is 800, however, on the slide it is only giving me the option to goto 528. Bellow are my facts, any help would be great!
Facts:
1. flashed jt's overclocked voodoo use clockwork, but did it through "install ROM from sd card". I am not sure if this is correct, but it seems to be running voodoo.
2. I have no idea how I need to have Setcpu set up.
I feel like I am blindfolded and I am trying to wack at a pinata.

In my neverending attempt to extend my battery life, I installed SetCPU. The underclocking with profiles has extended my battery some, but Id like more.
I know very little about undervolting, its a new concept to me. Could someone elaborate on it, and may've suggest voltages for each speed setting? I hear it can do wonders for battery life.
Sent from my MB860 using XDA App
just experiment, start with small increments (don't save your settings!!!) see if it reboots, if its stable for a day or two, increase it, when it starts crashing dial it back a notch.
Just like overclocking except in reverse and with voltage basically.
note I'm not sure re: kernel requirements, I haven't tried it yet with my atrix, and my current ROM runs stock kernel I think.
its hit and miss, for example on my SGTab I can't undervolt at all or else it crashes all the time, others get away with -100mAh across the board (bastards), but mine is happy on 1.1OC.

Yes, start conservative.
Another way to use setcpu to improve your battery life is to set a screen off profile to restrict the CPU speed to minimum when the screen is off.
I tried that one, but it kept stalling my phone when turning the screen back on when it was at the bare minimum.
EDIT: For anyone wondering, -75 seems to cause frequent freezes.

Any overclocking or underclocking is always trial and error. Rule of thumb is to only ever change one thing at a time in small increments, then test before adjusting again. Your approach should be methodical and not haphazard, i.e. in a PC change cpu clock speed in small increments until you fail to boot or BSOD, then change voltage in small increments until you boot and are stable again. Monitor temperatures all the time, and add cooling if necessary. If you take a methodical approach, and don't rush things, you can achieve surprising results with hardware/software tweaking.
What would be a good way to test once I increment a voltage?

A good test is to just use it as you normally would. If the phone doesn't reboot, you're good to go.

So, I had checked off set at boot on the voltage screen. Unfortunately, this has rendered my phone to continually reboot and freeze, as one voltage is too low.
I do have a nandroid backup from right before installing SetCPU, and backups of working voltages, but I can't get the working ones restored before SetCPU starts and freezes my phone.
Is there a way I can default or disable the SetCPU settings without having to reflash the ROM or a backup of it?

Do something CPU intensive also to see if it crashes, like play a game. You want to stretch the phone to the limits to test it at the most extreme condition you will use it under.

Maybe a factory/data wipe?

ddddddddddddd
you may try to use default stock kernel, on wich overcloking do not work.
re: setcpu, sorry I think you have to reflash... thats why you don't save the settings until you're sure
there is no shortcut way.... you may be fine for a day but next day it keeps crashing. Happened to me on my SG tab when I went to 1.2 for example, I thought it was hunky dory then a few days later crashing galore.
the longer you leave it for the better you are, its really your call to make. Some people prefer the extra speed and will live with a crash or two a week (not me, its my phone not gaming pc lol).
not sure how much stress testing you can/should do. Back when I was OCing PCs I would leave stress tests running overnight, but probably not a good idea to 100% CPU a phone overnight lol
Is it worth the hassle of flashing the new ics leak and roms? ive been running clean rom 1.7 ics and its been fine does the new leak and roms based off of it have a performace boost worthy of the hassle of relocking and unlocking again?
I was very hesitant at first weather or not to do it. Now that I've done it and am running cleanrom 4.0 its performance is better and i, myself, am getting way better battery life. Go ahead and do it! Look for Scotts tut on how to do it. Follow it and its really easy.
Its def worth it and its rather easy if u just follow the directions.

It's got some nice things in it that I like, but I have to mention this -- my phone's running a lot hotter. And it doesn't seem like any of the usual tricks (airplane mode, CDMA, etc.) are taking any of the load off the battery. Power settings say the juice is all going to the display, but I seriously doubt that -- it's staying plenty hot even when I keep the screen off.
Also, I've never liked the fact that this phone discharges while on even when connected to a power source. They really need to keep consumption inside USB's ability to charge. If you leave it on all day even while plugged in to power you'll have a low batt after a few hours. That's ridiculous.
Did you change your CPU governor to conservative? That is one of the things on my check list to do when flashing. It really keeps it alot cooler.
Also know that if you flash back to a gb Rom you probably won't have access to external memory

You should stop what you are doing and flash right now... If you follow the steps, you can be done in an hour. ICS is worth it.
Sent from my highly modified ICS Rezound.
Many have complained about issues with the kernel in ICS. On any build, it is vital that you not use setcpu or any other cpu scaling app. Don't change the max/min freq, don't change the governer, nothing. Perflock will constantly reset any changes and cause the cpu to run at either full throttle or full min - no in between. Until we get kernel source and custom kernels, this will always be the case. It's something HTC does.
Many cpu monitor apps will do the same. The link in my sig has more info, and a link to a cpu monitor app that is safe to use with our kernel.
Actually when I was on the second ics leak, and setcpu worked fine. I know this because I benchmarked before and after setting frequencies
Sent from my ADR6425LVW using XDA
benchmarking doesn't mean it wasn't running at full tilt when you didn't need it to. unless your kernel magically doesn't include perflock, it was.
also, there are some combinations of setcpu and monitoring that will work. at one point if i used setcpu, cpu monitor, and one other which i forget now, it would work, kind of. definitely not recommended.
Thats why I deaded mine. Phone was constantly overheating
Sent from my ADR6425LVW using xda premium
since i stop fighting with the kernel i've had nothing but great battery life and performance since the first ICS leak.
tsp, what i don't understand is why something like system panel, which shows you scaling (but doesn't let you change it) showed the proper correct scaling between 384 and 1512 and hardly EVER hit full throttle on GB, but on ICS, it's always showing full throttle.
then i installed your widget you showed me, and it showed constantly chagning like system panel used to on GB.
any idea why? which one is rgiht??

Agreed. I had set CPU try to disable perflock and limit to 1200mhz on conservative and it ended up being worse battery and slower overall.
You're exactly right I advise everyone I discuss the topic with to make sure and avoid trying to over ride perflock with a CPU management app. It causes a conflict in my opinion which is a huge battery drain and also causes excessive heat due to the process of fighting for its life.

the widget i posted is what you want. it should be scaling up and down, and settling eventually when nothing is really going on. the system panel that you tried clearly affected the perflock in some way. from what i understand, some apps/widgets look at the cpu itself, while others hit up the kernel for status. the ones that hit up the kernel are the issue. i'm not 100% on this, that's just what i've been told. all i know is my experience seems to match this.

Hmm, that's weird, cause I've been using setCPU with ICS on the Rezound for months and it works great! My CPU scales fine and hits all the frequencies its supposed to. The min and max frequencies do change around seemingly randomly, but anyone can see by watching the current frequency display that it is always somewhere in between the range I selected, and always appropriate for the system load.
I've always had CPU Master installed. I just removed it, we'll see how it goes.

No offense but if you can't figure out a slider, perhaps you shouldn't be undervolting.
Besides, most devs don't believe it saves battery anyway. After stopping undervolting recently myself, I'm inclined to agree

Nah, I finally learned how to do it using System Tuner. I was confused because when I moved the slider a bit, all the numbers changed and I couldn't figure out where the -25 was gonna be at. But I got it now.
Are you sure it doesn't attribute to battery life? I went a whole -100mV in general and for me it seems to have improved a bit. Not by much but it is noticeable.
Anything else you recommend? I'm completely new to the device, but I familiarize with tweaking very quickly.

You mean better stability after or during the undervolting? And what's your stand on OC? Do you also think UC saves battery as well?
Lol sorry, I just like asking people that know about these things before I try messing with them.
Yeah its more stable at stock voltages.
I recently stopped overclocking. I don't have any particular reason not to overclock. I was troubleshooting an issue and overclocking and undervolting should be the first to go when doing this. Just didn't have a need to re-overclock.
One thing I would say though... if you're overclocking, don't add more voltage than 1400 MHz is set as stock... that adds heat. Heat + clock = damage

I've restored normal voltages and hasn't happened so far. It's happened twice since last night and today. Both after undervoltage. I hope that was the cause.
