Last I heard OCing of ICS is not possible yet, so since you mentioned that, ICS is out for a good while.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Ah, yeah that would put that off for a little while. Think I might try it out before returning the phone so at least I know if I am interested in it but just gonna stick with the most stable gingerbread rom for now.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] xcrazydx:
Yeah there are a number of stable GB roms. nexusmod4, mhx superlite, seanz skyics, tpcv3, silver ROM. Read through the threads and see what people think. I prefer nexusmod as my daily, but all those are good

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Thanks, out of those the MHX, nexus and silver rom look to be the most up my alley, should at least give me a good idea if an aftermarket rom is for me.

One question I have is they all mention needing new Modem files flashed? This is different then the radios? Anything I should know about that aspect of it?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
agreed, all those x listed have proven to be extrememly stable. For best battery life with OC'ing and undervolting support use any of those roms with faux's 010m kernel. I was getting 1% battery almost every two hours with that, fauxclock app undervolt -100mV, and tpc v3, before i switched to ics
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] xcrazydx:
No, modern = radio. I always flash the radio before the ROM

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I just flashed the 010m kernel on the stock rom to play with that first and ran into something I am not sure about.

I tried both system tuner and fauxclock, at first everything was working as it should then I noticed that the 2nd core said "offline" and it won't seem to come on no matter what even while running stress tests. Any ideas?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Frogacuda:
It's more than that. It's a lot smoother and faster, better performance in everything, hardware accelerated UI, better multitasking.

It's the biggest update the OS has ever gotten, period. Yeah, it's still Android at the end of the day, but it's a pretty big refinement.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Yeah, I am starting to see that.

Back to the issue of the 2nd core going offline, After some playing around the only way I could seem to get it to come back online was to install SetCPU along with fauxclock. This seems to make the 2nd core come online but I am worried that running both apps will cause issues with them fighting over who has control?

I much prefer setCPU for the clock speed controls due to the profiles I can create but no voltage control. Is it possible to use the faux for voltage and the setCPU for clock speed control? Or am I asking for problems?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
Definately asking for problems. Only use ONE cpu controlling app. SetCPU does have better profiles but fauxclock has a few. Which rom were u using it with? It does disable the 2nd core by default to save battery, but enabled it as soon as it is required (i.e. games and/or benchmark.) TO check run a force close setcpu and run a benchmark, then home back to menu and run setcpu, it will show 2nd core as active.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I tried that, the 2nd core stays offline no matter what I do unless I run setcpu.

I would just run setCPU but then I would not be able to undervolt. I wounder if I could use one of these scripts http://xdaforums.com/showpost.php?p=20946429&postcount=574

That would take care of the undervolt and then use setcpu to handle the clock speeds? That would seem to be the best of both worlds.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
not recommended. Use system tuner instead. It has almost as much profile control as setcpu, but the voltage control of fauxclock. It also has an option to force both cores online.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I tried it but didn't care for it. Still didn't have the profiling options I want. I like the setcpu since I can set it to have different CPU speeds at different times/situations. Maybe that is not worth the power savings. Whats wrong with setcpu?

I also had the same problem with system tuner as well, it would not bring the 2nd core online.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Kagenui:
Im unable to find that option.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tomtommy306:
Just try faux clock to OC and undervolt....

http://rootzwiki.com/topic/4550-app09-beta-snapdragon-dual-core-oc-control/

Forcing both cores online kills battery and doesn't even stick on boot. There is no reason for needing both cores at the same time. It will show higher benchmarks, but nothing in real usage.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
Since you've installed system tuner, force stop system tuner and run antutu benchmark again and then load up system tuner, it should show 2nd core as active.

Which rom are you using by the way?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Ditto.

I am using the fauxclock but it would still not bring the second core online no matter what I did except for running setcpu.

I am on the stock rom for now, wanted to play with the kernel first. Using the faux 010m kernel.

I tried reinstalling the kernel for the heck of it and now it seems like the 2nd core is working as it should. The 2nd core stays offline till it is needed and then comes online. Maybe it was just a bad flash.

I just wish it had the ability to have profiles like setcpu. No reason to have it setup for full power all the time, I like being able to throttle it back in setcpu when not needed.

I like fauxclock due to how simple it is but with System tuner I am able to undervolt more without it locking up at 192 clock since I can up the voltage there only and leave the rest fully undervolted.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tomtommy306:
Setcpu was all I used until I got a samsung. The problem we have with the skyrocket is that setcpu will not hold the clock speed. For some reason they reset. That's when I switched to system tuner, then i found faux clock. I find faux clock to be just fine for OC and UV without having all the nonsense settings. Others swear by system tuner. User preference.

By the way: Faux clock will not force both cpus online. System tuner will under boot settings... its the 6th line down.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
If it didn't work after system tuner, i was going to recommend you reflash and check the init.qcom_post-boot.sh file located under /system, but since you got it sorted that's good. I personally used fauxclock under gb. I missed the profile control of setcpu, but the simplicity of undervolt was good.

Told you it was there ;) As for setcpu holding settings, which rom were you on? I've never had a problem with it, im actually using it right now, as it's the only one of the three that really plays nice with ics. And too be honest i hate system tuner, but I recommend options and let the user decide.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I never had a problem with setcpu resetting, worked great for me, just no undervolting option.

I agree I like fauxclock better then system tuner due to the simplicity, plus system tuner is just kinda clunky IMO.

Now that the second core is coming online as it should I have no interest in forcing it online.

Thanks for the tip, Maybe there will be an update with profiles down the road. For now I figure the fauxclock undervolted to -100mv (yes it is stable, tested for 45mins and gonna leave it on all night later) is better then full voltage with a lower clock speed. Be nice to have both options though.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tomtommy306:
I was on skyics with an old faux kernel. It's been months ago. I just tried setcpu again and it seems to have been updated and holding clocks well..... I just may have to go back. As for system tuner - I hate it too.... seems like way too much useless things there. Also... I knew about the force cpus online. Just don't recommend it.

Be careful undervolting... you can cook a cpu from lack of working voltage.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Ok, well turns out that the reflash didn't fix it. I uninstalled setcpu and suddenly everything was back to the way it was before with the 2nd core not coming online. This could also clearly be seen in the antutu tests as well, dropping the CPU only scores from ~4500 to ~2200. Clearly only running on 1 core.

Tried playing around with it and without setcpu installed the 2nd core will not come online no matter what. If setcpu is just installed it will work normally, offline till needed. I am at a loss as even after force closing setcpu the effect still hangs around but if I uninstall the 2nd core stops working.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
Actually this isn't really true. You can cook a cpu from overvolting and overclocking, but there are safety mechanisms still set in place for undervolt. Phone will simply reset. This are of coursed bypassed for OC.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Never had that happen in all my years of overclocking but then never done much underclocking. Has this actually happened to someone?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] icenight89:
nope, see my post above yours
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I figured as much.

Well last update before bed. After a lot of testing the only way that things will work as they are supposed to is if I open setcpu and have it set whatever settings I want and then close it. Then fauxclock will work as it should with whatever settings I closed setcpu with. If I adjust the settings in fauxclock though it will rever back to the second core never coming online.

If I leave setcpu running then the 2nd core will never shut off. Very lost at this point as to what is going on. Anyone have any ideas? Tomorrow I will try flashing some CPU scripts/reflashing the kernel again to see what I can figure out.

EDIT: last tidbit, If I click the clear memory button in task manager then everything reverts back to no 2nd core coming online.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Is there any app that allows me to only view the CPU clock speeds for both cores? Cpuspy doesn't tell me anything about both cores or even what the active clock speed is.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Ok, found an app that only monitors the core speeds and does not effect them in any way. It is not the best app around as it only updates once a second but it seems to work.

I uninstalled all the cpu apps, setcpu, system tuner, fauxclock. So I am now running purely on the kernel speeds.

Everything is now working as it should, the 2nd core is offline until it is needed and then comes online. Benchmark scores also say it is working properly.

The only problem now is lack of control over voltage and speeds. If I install system tuner or fauxclock I loose the 2nd core.

I tried just installing setcpu and low and behold I think it is working as it should. I can set whatever speed I want and according to the app the 2nd core still goes offline as it should.

Wish there was a better app monitoring though, not sure how much I trust this one as it says the 1st core never really drops down to idle speeds, course it could just be it's own interface causing the load that is keeping the speed up since cpuspy does say the speeds drop down properly but doesn't show me if the 2nd core goes offline.

The apps I am using to check the cpu core speeds are CPU info and cpu gauge. Anyone got a better app for only checking the core speeds?

So with these developments I am thinking that I would be best off just using setcpu to control speeds and then using a script for voltage control. Anyone see any problems with this?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Well, After a lot of reflashing, troubleshooting and overall just playing with it I finally got it working. Ended up useing the CPU scripts with a clean replash of the faux kernel and that got system tuner working at least. Fauxclock still locked the 2nd core no matter what.

With some tweaking of the scripts I think I finally got it the way I want it, I am forced to use system tuner but there are worse things.

Have it set to undervolt by 75mv for now although it took -100mv earlier without a problem.

So now that I have the kernel figured out time to start playing with roms. Think I will try the MHX first.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Well, I was just flashing the MHX rom and I noticed when reflashing the kernel that there are 2 versions of the 010m file. Both are same size and the files inside were modified about 10 mins apart.

I was using the file found here: http://rootzwiki.com/topic/14570-skyrocket263514010oc173ghzgpu-ocotguvslqbblnmar-09/

No Idea where I got it actually as I don't remember going to that site.

Then you have this file from here: http://xdaforums.com/showthread.php?t=1372690

I tried both back to back and the sky which I was using earlier works fine like before, the herc file adds a loading bar during the first screen during boot but also causes everything on the phone to be off by 90 degrees (it thinks the phone is being held 90 degrees off from where it is).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tomtommy306:

no one mention quickwiz rom with dag kernal?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I will take a look at those as well, now that I am getting the hang of all this flashing it is really not as bad as it is made out to be with all the panic over bricking the phone. If you know what you are doing and take your time seems pretty straight forward.

Gonna try a few roms over the next few days, might try some other kernels as well although the faux has been working pretty good so far.

Brings me to the current setup of mhx/faux.

Having 2 skyrockets side by side has allowed me to do some direct comparisons, figured I would give you are few that I can quantify.

My "stock" skyrocket is rooted and debloated via titanium backup with everything unneeded frozen (even more then on the mhx rom actually).

The MHX is currently underclocked to 1ghz and undervolted by -75mv. During normal use the performance difference between the clock speeds is almost unnoticeable except for high end games, for that I simply fire up system tuner.

Both phones have the same basic apps installed/running.

I have used both phones identically, side by side for just over 3 hours now, just basic phone usage, some sleeping, a few performance tests ect, no calls or games though as I could not do that on both phones at the same time.

The stock debloated phone is down to 81% battery and the mhx rom is at 91%. The estimates of battery left have always been a lot longer then the stock phone as well. The stock phone now says about 16hr left and the mhx about 1 day 1hr left.

The MHX phone seems to sleep a lot better as before I started using it a lot it was a lot further ahead, that is due to the underclock/volt I am sure.

The performance tests on both phones are ~6000 for the stock phone and ~4600 for the MHX while underclocked (about 7000+ when at full speed).

Overall I am really liking the MHX rom, stable so far and I think I am about ready to try a new rom if the storm doesn't knock the power out here.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] xxsicknessxx:
ICS seems pretty cool does the leak being used now come with all the featurels in that article
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I tried the MHX ICS rom earlier today, it was a little nicer and seemed like it would run a little smoother then GB but it also had some bugs. Combined with not being able to adjust the clocks I am just gonna wait awhile before moving to ICS.

Figure I might as well post the conclusion I came to for anyone else that comes across this thread. After playing with a handful of ROMs I decided on the MHX rom / Faux kernel combo for my needs. These fit what I want almost perfect, lightweight, power saving, overclockable and customizable.

Gonna flash it to my phone tomorrow, thinking about running the Antutu battery test on my phone tonight with the stock rom to get a baseline, not sure how good that test is though.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] xxsicknessxx:
Quickwiz is still imo faster more stable anything else i on silver now gb ice rom which seems sweet but its slowrr by 500 compaired quickwiz. mx rom is next one i plan flash its more complicated but looks best. you like it? what i wonder is you can nandroid like Any rom just switch when ever correct? no down side plus you can nandroid apps too which better then flashing imo.. any down side
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I could not find the download for quickwiz so I was not able to try it out. I also didn't like that is had not been updated since december, the phone had only been out for a little while at that point and I have got to think that improvements have been found since then.

Of all the roms I did try the MHX was the best for me, it was the lightest and fastest also the best battery life.

I do have a nandriod backup of my stock rom in case I want to go back and will make one of the MHX after flashing it but I honestly don't see me going back except for possibly to try the official ICS release when it comes out.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
Got a question, after a lot of playing around I have come to the conclusion that I do not like system tuner and do not want it installed if at all possible. I do still want to be able to adjust my CPU max speed depending on what I am doing though, have it underclocked for most things and overclocked for games.

I have been messing with Terminal emulator and realized I could change the max speed via a simple command line there. This got me thinking, there has got to be a way to have a shortcut on my desktop that will run whatever command line I tell it to with a simple touch thus giving me exactly what I want.

I have been searching through script programs though and have not found anything that has a 1 button shortcut/widget I can put on the desktop that will not bother me with another window I have to close/mess with. I would like it to do everything in the background.

This is such a simple task I have got to believe there is a way to do it. Anyone know of a way?

nothing is faster... or cleaner. However the creator isn't around anymore for some reason. i think got sick of trolls so I havn't seen a update for awhile. That alone means ... dead in the water which sucks because man that was a good rom. No issues

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] rojov123:
I've used the stock GB, ICS Perfection, Bonesketeer, Skyrocketeer and Alien roms. I'd suggest Skyrocketeer and then customising everthing until you have it just the way you want.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I might try that after I finish getting the MHX rom setup and tweaked and make a nandroid backup of it. I am really liking it so far.

Been playing with undervolting/clocking. Looks like I can undervolt it by -125mv at the 1ghz and lower clock speeds without a hiccup. It ran like that for 10 hours on stability test last night and was still running when I got up.

Gonna try going a little lower as well and then start playing with voltages at higher clock speeds. I know at 1.7ghz it doesn't like much more then -75mv.

Once I get that setup I will edit a script to set the clock speeds like I want on boot. During the test last night the undervolt and underclock meant that it didn't even get warn. Peak temp was only around ~30c IIRC.

Still looking for a simple way to run a script for a home page shortcut/widget without it bothering me, just click it and it runs it in the background. Anyone have a suggestion?

This should be q&a
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
That it is, I have now finished setting up my phone with the MHX rom and Faux Kernel. I am 100% happy. After a lot of playing around I finally got all the CPU issues sorted and setup how I want (still would like a way to run scripts in the background though).

After a lot of testing I settled on 918mhz as the best all around speed, handles everything but some high end games without a hitch. I then wrote a few basic scripts that I can launch with gscript that will change the cpu speed on command. Works great.

Also after a lot of testing I found that I was able to undervolt it by -125mv for everything under 1.5ghz. Above that I undervolt by -75mv. Took me awhile to get the script setup (modded version of the Gideon script) but I got it. Tested stable overnight for 10 hours solid and 20 mins each on all the intermediate speeds.

It now runs cool and MUCH improved battery life (heat is the enemy of battery life due to it being wasted energy).

Here are some before/after numbers for you.

Stock rom Idle power drain before debloating: ~10%/Hour

Stock rom debloated via TB:

idle power drain: ~6-8%/hour

running full tilt via Stability test: ~25% battery drain/~40mins

Antutu full benchmark: ~6000

MHX Rom/Faux kernel/My modded CPU scripts:

Idle drain: ~1%/Hour

Full tilt: ~25% drain/~1 hour 45 mins

Antutu Benchmark at 1.7ghz: ~7200

Antutu benchmark at 918mhz: ~4700

I tried the script on the other skyrocket I have and it took it as well with the same results.

MUCH prefer this setup over stock and it has been rock solid so far as well.

Sorry, first post, was not sure where to put it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] xxsicknessxx:
Did you flash that kernal or that's the roms. yes i cant see using ics with the possible bugs. not worth your phone bricking when try calling for help
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Texas_Ace:
I used the MHX rom and the Faux kernel with my modded version of the Gideon CPU scripts.

I am completely happy with the results over stock. Battery life is now what I think it should have been all along and it just runs a lot better.

At this moment I officially have 1 solid day on the phone, most of it idle admittedly but it has some use in there as well and I am only down to 67% on the battery life. It should now have no problem making it through a full day even with heavy use, on the stock rom it would hardly make it through a day at idle.

Only thing I wounder is if it is possible to undervolt below 800mv? With the current voltages I am stuck at 800mv for the lowest 5 settings, I think they would take a lower voltage.

Oh and last note, Those 2250mh "extended life" batteries you can get for the skyrocket, they are worse then stock. I tried side by side tests on both phones with an otherwise identical setup and while very close the "extended" battery did drain slightly faster. By 50% battery the stock was about 8-10% ahead, I am now back on the stock battery and battery life is the same between them.
