I installed CM10.1 nightly on my fascinate a few days back and it has been working pretty good. I had to install a memory manager to kill tasks more often for me. Then I remembered an old app I purchased a couple years back. set cpu, I went ahead and installed that and overclocked 1200/400 and it made the phone come to life. things seem to run really smooth. Not an advertisement as much of helpful hint in case you were not aware.
Thanks for all your guys help this week setting me strait on getting my phone working.

Your not suppose to use a task killer it hurts the phone very badly if you enable KSM in performance menu and zram you will notice it works the best. And set CPU has problems with jb like it could boot loop your device its better to use the built in performance menu

Yes, the stock Performance menu options are your better choice for over-clocking and memory management.
If you don't see the Performance menu under system settings, you need to enable developer mode by selecting About Phone, then tapping on the android version info about a dozen times.
Regarding zram, I'll need to give it another try... Definitely go with ksm enabled.

The reason task-killers don't work well is because android changed the way it handles multi-tasking so that once you kill a process, it will bring it back anyway, so that if you keep trying to kill things you will actually waste more battery because it will constantly be coming back. Android is actually very good at managing memory and doesn't need your help to do it.
I only use KSM myself because I was getting lag after a while using zram, but maybe it was something I was doing wrong with the settings. My other settings as of now are Interactive governor (min 200 - max 1200) and noop scheduler.

I usually use SIO but since I'm on the default kernel it's not an option. I tried ROW for a few days but it was making my music skip sometimes for some reason (especially while mutli-tasking while playing music), and noop doesn't seem to give me as many problems like that... so I'm not really sure. CFQ didn't seem to be that great either, so I'm hoping SIO will be added soon

I just gave zRam a spin and experienced noticeable lag with what I do as a result. I have "Allow purging of assets" and KSM checked.
For the I/O Scheduler, ROW seems better than the CFQ I had been running. Running the interactive CPU governor. 1200/100 CPU speeds.
Seems good.

Ditto, except with purging checked I'm pretty sure I was getting lag from that too after a while, so on mine I only left KSM on. ROW also does seem the best, however lately it seems no matter what scheduler I choose I get music that skips every couple of minutes or so, but I think that's a rom issue and not so much a scheduler issue. I've always used 200 minimum so that my phone is snappier when waking up, but that's just a personal preference.

I simply said that Helly is based upon CM10.1, and it is. Anyway, I just did a dirty flash (cache+dalvik wipe only) from the 02/22 build of CM10.1 to the latest HellyBean and it works fine. Actually, with the 1400mHz overclocking it was working really smoothly - although the rate of battery drain was apparent...
My hesitation in sticking with hellybean is based on my lack of understanding on how/if all of JT1134's ongoing fascinate-specific kernel/framework efforts, that are going into the CM10 nightlies, are being merged into the hellybean kernel... I guess I should go over to DT's thread and ask . Perhaps he's got all that happening whenever he merges the CM10 source updates...

Well I decided to try Helly Bean and so far so good, on SmartassV2 and ROW - no skipping music and everything is really snappy. Battery life seems noticeably worse than pure CM 10.1 but nothing that still can't get me through the day. I wish the Devil settings were baked into the rom settings like they used to be, it's annoying to have to use 3rd party apps to control it. I really like the standalone AOKP performance settings apk but settings don't stick after reboot

This is an undervolt test version of my new StupidFast Kernel v1.2.3. This is a TEST release (NO VOODOO). This kernel aims to be fast, compatible, stable, and have good battery life. It is based on my StupidFast v1.0.36.
Code:
Changes since 1.2.2:
Fix for the 0.5-1.0 second pause/lag opening apps/drawer
Scheduling Tweaks
I/O Tweaks
Changes since 1.1.23:
Stock 1ghz @ 1225mV
Changes since 1.1.14:
Tweaked minfree settings
tweaked io scheduler
more compiler flags for cortex/hummingbird cpu
tweaked wifi scan interval to help with battery life
Changes since 1.0.36:
removed custom boot animation to trim size.
using kernel jhash3 instead of jhash2.
optimized compiler flags for the hummingbird cpu.
changed some kernel scheduling timings.
BLN disabled by default (configurable with [url=http://forum.xda-developers.com/showthread.php?t=823922]this app[/url])
You will see that the custom boot animation was removed. It's okay. If you already have v1.0.36, 1.1.4 or 1.1.23 installed on your phone, the animation will stay. If you're new to my kernels with v1.2.3, your old boot animation will be there.
I'm not seeing any lag on the phone. Gallery opens pretty much instantly. Settings->Applications->Manage opens pretty much instantly. Launcher Pro+ pretty much instantly appears when the phone starts up.
Testers could NOT find any audio problems with this kernel using the media player in JT's Clean ROM. I've tested Youtube and Pandora and have had no audio issues. Also, we couldn't find any issues with USB mount/unmount, settings changes, etc.
As always, if you find a bug or what you think might be a bug, let me know. This is NOT the final stable release of the 1.2 kernel. Stay tuned to #samsung-fascinate on FreeNode or @geeknik on Twitter!
Download:
http://dl.dropbox.com/u/6088006/stupidfast-test-v1.2.3.zip
saps from #samsung-fascinate said that v1.0.36 was "far and away the fastest real world kernels I've ever seen, period"
If you like my kernel, show me some love. Donate today!
Thanks to saps, jt1134 my beta testers and the kind folks that donated cash to the cause! Keep fighting the good fight!
sweet. dowlloading now.
Downloading also.
I like your kernels, but I just noticed I am getting a super weird output in ADB when I try using that. I also have superdark ROM so it could be either one.
Ok, I just rebooted and checked again and all is running fine with 1.2.2 in recovery, but not in running android system, must mean its the rom.
Downloading now.. went with full full wipe with jts clean, and still getting popping, on asop player, double twist, pandora
Besides the battery life which is supposed to be increased, is there any other benefit to UV ???? Longer processor life, runs cooler, etc.
What are the drawbacks, if any ???? Does performance take a big hit, etc.
I'm asking more in general terms. Obviously I will observe first hand with this kernel, which I'm downloading now.

In theory, as I know computer not cell phone, UV will allow it to run cooler, which does mean last longer (but is that really a problem?) and use less juice while still being as fast as before. If it runs stable you will not see a performance hit and it will better with the battery. It will just freeze your phone if its too low and requires more juice, really no harm can be done, overvolting is more dangerous as that burns up cpus, but you overvolt to make the higher frequency stable. Simple overclocking principals apply, you want the lowest voltage for your cpu frequency.

are you upping the CPU to 200mhz to run those? I am doing that and its just fine, although I never had a popping problem at 100mhz either. I just set the min to 200 because that cleans up a little bit of the lag too.
Possibly related, every once and a while my phone will just decide to press a soft key on its own, what is that? (that causes a slight skip in the music when I am playing it)

see if listening to it while hooked to power recreates the problem... i noticed for me atleast its only when plugged in...
I have it up to USB and its not skipping or popping right now, I am also using mixzing
v1.2.2 is the least fastest of all the geeknik kernels for me. There is 1 almost 2 second pause loading and exiting apps unless it was already in memory.
Still faster then everyone elses kernel. And so far battery life looks to be way better on this one but I haven't had it long enough to say for sure.
Nothing has changed on my audio popping issues so I am still using SetCPU at 200min still. I am short 6 hours of battery life like this by my best guestimate... which isn't a big concern for me- just reporting for those who need to make it thru a day without a charger nearby.
Never had any FC's with USB.
Touchwiz/JT's Super Clean ROM
And a thank you to geeknik for all your efforts! love how your pumping these out!
Kernal runs great! No unwanted sounds from the stock music player in jt's rom. USB works just fine. Thanks for your hard work!
are you using setcpu? if so that helped me fix it bumping min to 200... any one else having the problem might try that...
Interestingly enough, this kernel does seem a touch slower than the 1.2.23 regular voltage kernel. Hangs just the slightest bit when firing up and exiting dolphin browser and xda app. Still, appears to be MUCH better with battery life, as the previous geeknik kernels were ravaging my battery.
Definite progress but not quite perfect imho. Still thanks for all your work geeknik, you're killing it with these.
Also fyi, running custom blackhole, with sns and lp

This kernel is running fairly smooth, like the other 2. I can deal with the extra 0.5 second delay when first opening an app, as long as BLN is optional and battery life is extended. Thank you very much for taking the time to come up with these kernels for us. Other kernel providers tend to make their products less accessible for us XDA users, but you take the stress out of the search. Thank you again.

The uv kernel is a winner of course. I test these kernels for geeknik before he throws them up for the masses. Not just running quadrant [although I do that too] but going thru the real phone stuff itself. The manage applications load, replacing new dock shortcuts, gallery, apps and stuff everything we actually want to see improve with.
I for one never had battery issues with previous stupidfast kernels but I know some did, same this music crackling. It seems to me most of you that do are either running blackhold or deodexed rom though and quite humbly I'd look their for your culprit moreso than the kernel. If there was a music skipping issue from the kernel itself it would manifest itself across the boards but it doesnt.
Anyway, battery life is going to be stellar trust me, under light-moderate use Im only using like 2% per hour here swyping 8-10 texts per hour here, very good indeed
Hey Saps- I see ya on all the forums and your contributions have really helped me out...
That being said I keep seeing an overlook of real world usage in these testings. Can you guys test beyond stock apps? I mean checking stock should be the first thing you do obviously but how many people use the stock music player or the stock browser, etc? I am betting most the people that have the knowledge enough to test these kernels and ROMs aren't using stock functionality and apps.
Please test this kernel with the PowerAMP or Music PlayerPro music apps before writing off the issue.
Use Dolphin to check the internet, etc. Use K-9 to check email, etc.. ya know- use the popular apps during testing also if you could?
Audio cracking, FC's with the USB settings, and I even heard mention of live wallpapers having issues. These reports coming from 3 reported different ROMs.
How are you missing this?
I myself have had great success with battery life on the Stupid Fast kernels. Better then stock kernel for sure. But I've been having to run my battery faster by using my workaround to avoid the music crackling.
JT's Super Clean ROM using TouchWiz
Just suggestions so we can all get on the same page and enjoy these badass mods.
P.S. What ROM are you using during testing of this kernel? I'll gladly switch to fix the issues
I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?
Just try clearing app data rebooting and reinstalling the app. That problem has happened to me every once in a blue moon and that fixed it for me.

Thanks, I'll try reinstalling the kernel.
Which app are you referring to? because I had this problem no matter which app I used to change the governor (Extweaks, voltage control, setcpu).

Hi Guys,
My first post here. I am total noob. I rooted and installed the newest ShoStock2 on my at&t galaxy s2. Everything works perfectly. I couldn't be happier. I also went bought the setCPU for overclocking it. That too seem to be working fine.
My question is. I didn't set up any voltage requirements. The only thing I did was to set it to 1600 MHZ and 200 min and change the governor on the bottom to Lulzcrative. Will this work? Do I need to actually do something with the voltage? am I really on 1600 right now? I cannot tell.
I ran a quad test (I now it is meaningless in real world) it came 2818 yesterday. I ran it again this morning ..... It froze and took my battery from 45 to 9 in less than 3 mins!!!!!! The phone got really hot. I took out the battery right of way. The battery life showed 23 percent this time.
I got little afraid of the quadrant testing ... The phone seems to run good without that but I am not sure if it is set up how it is suppose to.
Could someone help me out please? I tried reading the forums and that is where I got the idea in the first place to overclock it.
So to summarize it, I guess phone is fine right now but I am not sure if I set up setcpu out properly.
I am on the newest shostock2. I have galaxy s2 on att. I am pretty good with computers and phones but not sure about voltage and other problems with relating to setCPU.
Thank you advance for helping me out.

Lots of questions there. Phone overclocking is the same and at the same time different than PC overclocking. I too bought SetCPU and due to bugs and problems have completely abandoned it. Honestly with the exception of running an epeen benchmark there is little incentive to overclock. Find a newer Kernel (I use NEAK which has no overclocking ability) and install it, performance is stellar. You really have to ask yourself, is my phone slow enough that I need more CPU power to make it faster?
To see what time your CPU is spending at a given clock speed, download CPUSpyhttps://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&feature=nav_result#?t=W251bGwsMSwyLDNd, you will be surprised to see your phone spend very little time at it's max clockspeed.
Due to the immaturity of the fab process for our CPU's (well SoC), what is a stable overclock for one person might not even load for another. These CPU's are not like an Intel Sandy Bridge, with 1Ghz of free overclocking, nearly guaranteed. You can certainly play with voltages to try and attain a higher overclock, but at the expense of CPU lifetime, as well as battery.
Additionally, it takes a new Kernel 3 or so full charge, discharge cycles on a phone to really 'settle in' and 'learn' a particular phones battery, while yours got hot, which to me indicates an endless loop of some kind running in the background.
My advice would be as follows: Choose a ROM you like, feel free to play with different Kernels, again, I use NEAK, which does not work for some folks, or crashes or whatever. Give it several days to 'settle in' and if your still not happy with performance or have stability problems, try a different governor/scheduler. You really need to establish a good, solid baseline of your phones performance and make small changes and give them long enough to establish any changes to your phones overall stability. Basically running cowboy through your phone and making changes will have a negative overall outcome. Make small, documented changes, test and see what overall effect this has to your phone's stability and battery life, and make another change.

I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?

Thank you so much for the information. Could I simply uninstall the setcpu and go back to normal? Simply reflash the rom and/or kernel? I really like shostock2 with the cherry picker kernel for now. I want to give them a week of try to make my mind. Before the setcpu I think.I was better off
Thanks for the help by the way. I appreciate it.
Thanks for the update about the new siyah kernel. Glad it wasn't just me with the issue. I was going to post this question in the siyah thread but am new to the site so didn't have permission so thanks for finding me all the way over here

Lol what exactly have u heard? If it was causing problems it would get pulled. The only thing I can foresee happening is someone flashing it and then not flashing a kernel or something. Which would be user error.

I'm just going off what I've seen in the Siyah/NEAK threads. Most of the lock-ups/random reboots I've heard people having had used the cleaning script. Either that or its just coincidence.
I may be wrong but I think that using the kernel cleaning script actually solved most of the lockups. Perhaps I misunderstood the threads.

Hmm, well I've just manually wiped cache and dalvik and have never had problems between roms/kernels.

What I'm running:
Latest NEAK kernel + AOKP build 36.
Issue also occurred in Phonebricker + NEAK (sammy version).
My issue:
Occasionally the OS will get extremely slow, like you would expect if the phone were running at 100mhz or something. Everything continues to work, just reeaaallly slow. For instance, music playback gets very electronic-y as sounds are stretched out, tapping one of the capacitive buttons takes 5-10 seconds before vibration/feedback, and another 5-10 seconds before a menu pops up. I managed to get the NEAK configurator open and scrolled to the CPU tab, and it claimed I was at 1200mhz - though the phone didn't even get warm so I'm skeptical.
I'm guessing since I've done a full wipe between phone bricker + NEAK and AOKP + NEAK, the only thing in common are my apps and the NEAK kernel, so it stands to reason it would be one or the other causing this. My wife's GS2 is running AOKP + NEAK as well though and we haven't experienced this problem on it yet (but it's intermittent so it might be there, just hasn't happened yet). I'm currently running conservative governor + SIO, but it has also happened on conservative + NOOP.
While I could just change a bunch of sh!t and hope it goes away, I'm more interested in figuring out what's causing it, and fixing it properly. How can I figure out what's going on? What will log this kind of thing? What do you guys recommend?
Thanks!
this is really easy/simple. flash a different kernel. all devices are not created equally so you need to just try everything that we have and see which best fits your device.
if you had this issue on 2 different roms with the same kernel then you've answered this question in your post for yourself. it wasnt even necessary to post this dude. change kernels. done.
some phone like neak kernel, some phones dont. some phones like siyah, some phones dont. you cant "fix" that unless you get a different phone and try neak again. but even then it my not "fix" this issue because nothing is broken.
Well, what if it's something as simple as the governor I'm using or an undervolt setting? I'll probably flash back to your kernel though, but again it'd be nice if I could figure out exactly what the phone is doing when it's "super-lagging".

If you're undervolting when this issue is happening, change it back to regular voltage.
I can attest to the slow downs and the screen lock ups. I have been using Tasks kernel for the past week and a half. Going back to try NEAK one last time. If it gives the same results I'll have to give up on it. I don't under volt hardly at all by the way. Like maybe -25 per step so it isn't that, and when I first experienced the issue I tried Evey possible io scheduler / governor combo under the sun. All yielded same darn results.

I've only used Task's (CM9) kernel and NEAK, and I haven't yet experienced any slowdowns with Task's, but I really have no idea what kind of optimizations his has, haven't found any information on it published so I can't say what's different between his and the NEAK kernel.
What kernels have you had problems on?

Stock & Siyah. My issue with it wasn't major; it just isn't as polished as GB. The difference is noticeable.

When mine gets laggy, I usually pull out the battery and put it back after 10 min or so. If you are leaving the phone on more than 2-3 days at a time, that could really hurt the memory and phone performance. The phone usually runs on 300 mb but it will run about 700mb ram after 3 days (even force closing everything).
It is not mentioned so I just wanted to cover all bases
After posting about giving NEAK another try, I did. And within 10 minutes got an extreme lag slow down while typing. Didn't touch any settings kernel side. So I flashed siyah kernel and so far no problems. Sux too. I liked NEAK.

I have been running Siyah with Task's AOKP and have had zero lag and great battery. No UV or OC.

Posted this in NEAK thread but also posting it here:
I just installed the new AOKP, used kernel clean script and installed NEAK 2.0.5x, then went into the NEAK Pro config and changed my governor to Conservative and sched to SIO. Rebooted, opened Scramble with Friends and immediately got superlag.
Turning off the screen and waiting 20-30 seconds fixes it (long enough for the phone to go to sleep), but nothing else short of a reboot will help. I can leave it like that for an hour (if I don't let it sleep) and it'll still be uberslow.
Here is my project that I have been working on for a few weeks now. It is currently for Testing Only in its present condition.
My goal is to adjust the settings of the Kernel to squeeze out as much battery life as I can without sacrificing performance to our phones.
It is initially based on the DSC Kernel.
I have added I/O Schedulers as well as numerous Governors. I intend to narrow down the ones to just maybe 2 or 3 of the best ones. as well as adjust the CPU settings and speeds to give the most optimum configurations.
Here is the list so far, but will be reduced with further testing.
I/O Schedulers
cfq
deadline
noop
sio
vr
Governors
brazilianwax
conservative
interactive
interactivex
lagfree
lazy
liionheart
minmax
ondemand
performance
powersave
savagedzen
scary
smartassv2
smoothass
userspace
The biggest hurdle to get through right now, since it is my main focus, is the the screen is rotated which makes it NOT useable yet. Once I get past that, I can adjust settings and make other modifications.
Any suggestions or help will be greatly appreciated. I created a Github account and will try to figure out how to use it. I have also attached a Test5 Kernel as well as a reset Kernel.
I am reserving this section just in case I need it
Until the attachments are working again on XDA, I will post links to files shortly.
Does those kernel can patch to MIUI / Longhorn / DSC / CM ?

if i not mistaken.. the kernel is being optimized for longhorn ROM... and it is based on DSC kernel...
if my understanding is correct...
Actually it is based on the Phoenix Kernel. I intend on it it being a universal kernel. Once the base is setup and working, then I can test and tweak it further.
i have always felt droid does too much in the background causing quite an effect on battery life.
Too many processes auto loaded.
This may not be at linux kernel level, but rather above it on the droid's scheduler etc.,
Basically what i would like is to do is disable auto starting apps.
for eg., i dont want yahoo messenger ever to be in process list if i have not started it. and when killed should stay killed.
I guess that should improve the battery life quite a bit.

oh... we have apps called autostarts though (search for it).... but becareful... you might accidentally disabled key apps for the phone to function properly... last time i disabled so many to the point that i need to reflash the ROM back... lol.. silly me...

Yes. I use it in my Streak. But it kind of feels useless at times. Sometimes apps on reinstalling, get reset from autostarts..
its just no where close to 100% effective.
And it doesnt retain state. TI backup and full restore doesnt return it back to previous settings.
But actually to launch or not should be a user control, not a forced sarcastic maybe that droid is given me. Hence a deeper level of control is required.
sad to say but that how android works unfortunately... and since i cant afford iphone and also i pretty much hate symbian, well... had to stick to android at the moment.. lol...
Thanks Ten,
Do you think Bluetooth driver update?
That is a possibility. But that will be later down the road. The Kernel itself is a lot of come to go through, so baby steps right now.
Hey.!Ten just an idea .!!! Can u add drivers or edit kernel for (10 point multitouch screen)

Hello
I'm using the Ultima rom and I need help undervolting. In Stweaks there are only sliders per frequency but on stock with Siyah kernel, there was a drop down list with -25 and -50 on it.
I don't know how to edit using the sliders. How can I get the drop down list back?

check for boeffla kernel it has drop down list but make sure it works for ur Rom or ull screw it up
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.

I've been undervolting for about 3 years but I have noticed no effects by ceasing this activity. I have noticed improved stability though. I actually notice more effects by tweaking things like CPU sample times etc
I use SetCPU

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 see. Thank you very much for all this.
But I ran into a problem. Screen flickering. When the screen is off and I press the home button, a bright flash appears then the lock screen turns on. That's the only problem I've been having and it's scaring me like crazy. I've seen some flickering issues but none like this one. Do you think it has to do with the volting? 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.
