I've been experimenting with several new ROMs and have found in every case that when I install SetCPU (either choosing automatic/HTC Hero profiles) it causes dramatic slowdown on my device to the point where I just can't bear to use it. On some screens it takes 5-10 seconds to load and when I am typing a message it is often an entire WORD behind my pace and constantly trying to catch up - for the record I am no champion speed texter!
With SetCPU uninstalled my device goes back to normal.
I purchased SetCPU last year and have always enjoyed it, but it seems with the new 2.1 ROMs, it causes more bad than good. I was in the sprint store the other day looking at the EVO and I happened to use one of their stock Hero's and the difference in speed between that and mine was STAGGERING.
So is it SetCPU by itself or both it and 2.1 ROMs?
Are you using it on an oc'd rom? id not reccomend using a oc tool, manually throttle ot to where you want
this doesnt belong in dev
From what I understand is that you don't even have to use an OC tools such as OC Widget and SetCPU with Toast's kernel. I may have read this wrong so I'd ask someone else. It is built with the On Demand throttling, I believe. Therefore, if you use a 710Mhz one it will scale from it's lowest freq to it's highest when needed. But again I am not sure. Ask someone else.
Yeah Ive been using the 710 dam ker and I was fine for a week then all of a sudden lock ups and crashes when answering the phone etc I wiped and started over and its good I do want to clock it a bit though so any good recomendations would be great
(I figured to post this in Android Development as it wasn't really a fit for any other forum; and made its own thread since multiple ROMs and threads use non-stock kernels.)
I ran into an issue running JAC's OC/UV kernel, as detailed at http://forum.xda-developers.com/showthread.php?t=806116 . Essentially, whenever any kind of audio was playing, whether through headphones or the speaker, local media (i.e. mp3 player) or remote (i.e., Pandora), at some point the phone would just.. die. Capacitive buttons wouldn't light up, no unlock; music would die; and basically a battery pull was required to turn the phone back on. adb logcat reports nothing - you can see the audio streaming, then the logcat shut off with the phone.
Based on the thread above (and searching the Bionix thread), it seems that a non-stock kernel does this. (There are only a couple of posts out of the thousands on Bionix's thread.) I have not tested KingKlick's kernel, only JAC's; perhaps KK doesn't suffer from this. This issue is independent of overclocking/underclocking the phone (verified by setting JAC kernel to 1000/200, then uninstalling setcpu); Voodoo lagfix (verified by disabling lagfix and running audio for about an hour); and ROM (tested using multiple versions of Franken-Twiz and Hybrid - maybe there's an inherent issue with eugene's mods, but I haven't seen any other posts.)
I suppose this thread serves as a warning/bug report for anyone that might encounter this issue if running a non-stock kernel. The best way to resolve AFAIK is to revert to a stock kernel.
Thank you for posting this! My phone had suffered from this at random times since I started using JAC's kernel. I asked about it in a couple of threads but never got a single reply. Glad to know it's not only me
I'm running the same kernal and about 20 minutes ago running pandora my phone just turned off too and had to pull the battery to restart

Had that issue at the Gym the other day, not even on Bionix.
I had similar issues, also with the KK Kernel, its not just JAC's kernel. You don't have to pull the battery either to get out of the freeze, you can hold the power button for several seconds and it does a hard reset.
I have found though that the KK Kernel is less likely to do it if you set your setcpu to 400 min and 1000 max before using pandora. Those settings seems to have worked for me every time..also after setting up pandora make sure to fix permissions with rom manager.
Just a little work around, try it to see if it works for you.

Actually this is a known problem since even the G1.
If you have anything like setCPU, which I do, and you set the idle or lowest speed lower then 400 Mhz the phone will more then likely freeze up when playing music or when going to idle.
I don't remember off the top of my head what causes it to do this when it goes below that certain Mhz, but Im sure I or someone here can dig the old thread up.
Man without this thread I could never get pandora to work with a custom kernal. I setcpu at 400 min and 1000 max and not a single freeze. Thanks so much for posting that tip, you made my day.

Ive had this problem to.... but it was ONLY with Jacs 1.1, I revert every ROM back to his 1.0 and have no problems. Everytime I dont, I get a phone freeze.
I was having this problem with jac's newest kernel so I went back to his first OC/UV, it is a known problem and he's working on it according to his twitter. how I got around this is I used his OC script and got rid of setcpu, from what Quadrant says I'm still running 100/1200. Hope that helps you guys

Interesting. I'll try installing JAC OC/UV/Voodoo again and see if this observation is consistent.

Yeah, I think the problem only exists when you use the OC kernel with setCPU, and setup setCPU under 400Mhz, other wise the kernel with out setCPU works just fine when it goes below 400Mhz.
Once again I don't remember why it does that but it has something to do with setCPU not being able to initialize properly after the phone goes idle and falls below 400Mhz.
Would have to agree. There's a bug somewhere. Not sure if its limited to jacs though.
Currently on masters rom kk. Only problem is pandora.
i had this problem too. kinda disappointed cause the kernels make everything run so much better. so i had to go back to using stock cause i listen to music a lot :/
There's definitely some hardware variability, because I can't recreate this bug. I listen to music all day long (MixZing, Slacker, Pandora) running 1.8 w/ JAC's OC/UV Voodoo. Never seen this.
Likewise with Jacs 1.1, had a couple other weird issues running that specific kernel too, not a single problem when I flashed back to 1.0

i get this same thing. ive had it happen with SetCPU both installed and not. right in the middle of a good song bam phone just shuts up. walk over to my toolbox and sure enough the phone is in a state of being divided by zero and only a battery pull lets it return to the world of the living. not greally a good thing when i have sevearl iphone dorks in the shop and they pop on over to my speakers and they say out of the way lets plug in a REAL phone. makes me want to scream LOL. ****ing iphone >_<
i retort with soooo when you get it out of the box....thats it right? nothing can be changed right? oh look that program sucks....what you cant make your own? ...yea...i thought so. hey look im making a call in the scrap room surrounded by 4ft thick concrete walls.... i got full bars lol. they got nothing in the empty parking lot cuz there holding it wrong LOL

I tried that though, as you can see in the thread I linked to above. Uninstalling SetCPU didn't help..
I think it's hardware.... One of the unlucky ones....
Try with a stock kernel. Jac and kk kernels do uv by default, which is like overclocking in reverse. It has the same possible stability issues.
Alright so over the past few months with my Captivate Ive come across a few things that i havnt really been able to find a definitive answer to.
Lets start off with my biggest question, Ive noticed with this phone vs other phones (especially the evo and the iphone even) that the volume coming out of the headphone jack for music is pretty darn quiet. Are there any programs that can change volume output or dialer numbers I can enter to bring up a debug menu to change this?
Next question is which is the best overclock kernel(s) out there for the captivate? And if im using a rom like Cognition can I flash it through CWM? Also if there is one that exists...is there an overclock kernel that doesnt cause Charge of Death?
While im on the subject of Overclocking and Kernels, I havnt really found a great explanation on how to use Voltage control and what exactly what it is youre doing when you are changing the sliders around. And vs. other android phones with custom kernels, what makes ours different to where setcpu is advised NOT to be used?
Audio boost is an app that is supposed to improve volume, it is not free but not expensive.
You can use oc kernel with cog. Glitterballs appears to have fixed charging death on his kernel, should work with cog, sentiro kernel works with cog but I think there is a chance for charging death. Either way do not use ak kernel that hours over 1200ghz
Use sgs kernel flasher app free on market to flash kernel
Voltage control app is easy but unless you are looking at it , it is hard to explain

Thanks! i got Audioboost and that works pretty well. As far as glitterballs kernel...in the thread he said he removed it for now for some reason?
and what did you mean when u said "Either way do not use ak kernel that hours over 1200ghz". Also can you atleast tell me what the sliders are doing when you are changing them from 100-75-50 and so on?
Man I suck at swype.
Ok glitterballs had removed later versions of his kernel because of some bug reports. I am on version released on 12/23 #7 and it is very stable. It is linked in the op but if you were going to use it I would suggest posting in the thread and making sure you get the right version
I meant to say either way I would not use a kernel that oc past 1200ghz
The sliders in voltage app is to under volt. So at the different frequencies you can reduce the juice the phone uses. Can save battery life, but depending on your settings could freeze up phone. I personally do not play with under volt

So i download a kernel off of the kernel manager from the market, I think its called thiamets? But anyways it has the option to go up to 1228Mhz and i think even 1256Mhz but my phone always freezes up at 1228Mhz. Is there anyway to get this stable or is that asking for to much. I just want to do it keep in mind I usually run my phone underclocked except when playing games...
It was noted many times that most Nexus Ones will exhibit instability over 1150 MHz. You can find warnings in most kernel threads.
Try the phone stability mod here: http://forum.xda-developers.com/showthread.php?t=1059423
I haven't tried it myself, but it could work.
Why do you want to overclock your phone that much?
Hello all,
so in the effort to make my O4X last like a normal smartphone when not in use iv'e rooted it,unlocked the b/l and flashed custom kerenal.
i did managed to go from an avg. -10%/hr battery drain to 5%/hr but still even if i dont use the phone it will go down alot.
i've tried setcpu,trickster,no frills cpu and none of them could really keep the cpu in the freq. i want. it shos sucess in appling the values but then it jumps below and above the value's iv'e set.
what can be done?
thank you
Have you tried no-frills cpu setting to prevent system for making changes to the cpu frequences?
Yes.. Still not sticking and ignore the freq. I set
@genia.m which kernel are you using ?
Currently I'm on the latest Werewolfjb.
It happened with stock kerenal too..
Might be the rom's fault?
Well it can be, I believe it is the kernel but still, try to change your rom to one which has been reported to not having the baseband wakelock and similar wakelocks . It is the Nvidia Tegra 3 which overrides the definitions and sets them to default. It used to happen with me in stock and on cm too, but I changed to another stock rom , a modified one, and is working like a charm, no stupid wakes.
Try and post the result if you want !
