Undervolting, Overclocking and random freezes.

I'm running back into the problem of custom Roms freezing on me, no FC's, just the phone freezing and requiring a battery pull to re-boot. I odin EC05 plus, let it boot and sit for a few minutes, reboot, let it convert, flash cwm purple, wipe, then flash whatever rom, and eventualy they all freeze.
The only roms to never give me that problem is CM7, MIUI and true stock.
Tried everything, except for not using the stock cable, but even still, cm7 and miui have no problem.

I've had the same problem with SRF 1.2...and I linked the problem to certain SetCPU settings like on demand and userspace and to undervolting to much in the higher OC'd frequency ranges...even though I've experimented wih these settings and found a somewhat stable medium...I still get the random freezes once in a blue...I don't know what else it could be.

Right now I'm on SRF with the 1.1.1 Kernel, using setCPU 200-1000, cfq, and no undervolting at all. I was on the 1.1.0 Kernel using voltage control when I had it freeze. I've uninstalled voltage control and galaxy tuner. Oddly enough setcpu dosent fc when I go into the voltages, which it did a few flashes back.

What problems do you think Galaxy tuner was giving you...I'm using it right now?
Sent from my rooted, suited, & booted Epic 4G kno dat!

I wasn't sure, but I figured with using setcpu it would be best to uninstall it so there wasn't any sort of conflicts between the two.
Sent from my SPH-D700 using XDA App

I'm not sure I follow where the conflict btwn those 2 apps would be...once controls cpu speed, governing, and voltage...and the other controls screen brightness and sound attributes...not trynna be a smart ass I'm just trynna make the connection?

In galaxy tuner there is some options for overclocking, as well as IO scheduling.

You didn't read my OP, I have no problems at all with FC's, my problem is the phone freezes and I have to pull the battery to restart.

At any rate. Sounds like your phone is garbage. Make sure you enable journaling to help mend the fc's.

If you aren't undervolting and are having this issue on multiple ROMs, it sounds like a conflict between some apps like you suspected. That or something is not right with your phone. Freezes happen to me when undervolting too much but you aren't doing that....edit...maybe your phone just doesn't like the 200 minimum that well. If I remember right, stock values are 1000 max and 400 min.
Sent from my SPH-D700 using XDA Premium App

I'm wondering if maybe the 200mhz is whats doing it then, I always figured 200-1000 was stock, and the phone would only freeze when the screen was off. Right now I'm using setCPU with it set at 200-1000 with cfq IO scheduling. If I have more freezes I will try bumping up to 400-1000.

im currently undervolted with the aosp rom from dub with genocide's final kernel...200mhz is perfectly fine...if 200 is underclocked too low or other frequencies are too low...sod or freezes will happen with the frequency with the wrong voltage is reached..i have setcpu and voltage control together but mainly use the new setcpu...when idling, i see a 1 percent draw in 2 hours and 6 minutes...and use stability test whenever you underclock to see if it safe to use...just my 2 cents...

CPU apps

I'm having trouble finding a CPU app that works perfectly with this phone. I've tried setcpu, CPU master, system tuner, and nstools. What's everyone using to oc this thing?
Sent from my SGH-T989 using xda premium

Depends on which rom your running but in general...you should use none. Most roms already uv and oc and if u use an app it'll butt heads.

My issue is that it seems like my phone is skipping steps all over the place. I'm using cpuspy and the usage jumps between Max/min clocks. I'm kinda not digging that. Its the same with every rom i flash.

That's not an issue with your cpu app. It has to do with your governor (the thing that controls how your CPU scales). Most ROMs come with ondemand by default which pretty much does exactly that, which is jump from min to max as needed. If you want something that scales more, you should look at conservative (for better battery life) or lagfree/interactive (for better performance). Lagfree/interactive are only available on select kernels though (whereas conservative is almost universally available). Streamline definitely has them and I think synergy does too.
Also CPU apps don't butt heads with the ROM/kernel default settings, it just overrides the default settings.

Yea I figured that but this is the first phone I've had where on demand performs that way. I've had a nexus s, epic 4g, evo, and a g2 and they all scaled across the steps ondemand. Ondemand on this phone works like the min/max governor. But your right conservative scales across the steps well. Just a bit choppier. About to install nstools and mess with the threshholds and whatnot.

Gta 3 lags badly

Does anyone have suggestions on how to run gta 3 more smoothly on my wonder?
Sent from my GT-I8150 using xda premium

Did you use a custom rom or stock rom?
Sent from my GT-I8150 using xda premium

I agree, it always chrashes on my phone, havent tried to solve it though. V6 supercharger might help, also Gamebooster Root (paid app) might help. Im not sure because i havent tried. Please report if you get some improvement
Sent from my bananaphone.

i played gta 3 with no lags

Maybe you can try to set cpu governor to perfomance (means it will run at 1.4Ghz all the time). This helped me with other games, but I haven't played gta 3.

Will that cost battery?
Sent from my bananaphone.

Of course it will cost you battery. More than "ondemand"
Cause the CPU Speed is always at 1,4GhZ; which is alot.
And your device may get very hot..

I also couldn't remove ultra gaming mode from game booster. Have removed the app, now my phone seems like it is out of ultra gaming mode because its not as hot as it used to be

(Q) CHUNKENESS (LAG) on all roms and stock....why?

I just did a full unroot twice and being on stock seems somewhat smoother and less "chunky" than any of thr custom roms I have tried. All clean installs. I would appreciate any idea why I still have stutters and not fluid motions on anything.

Truthfully...it's not.

This rom when installed correctly blows stock out of the water. Add the Nova launcher..and tweak the settings...and you will see exactly what I mean.Use the latest TWRP..and wipe correctly...and you won't want to go back to stock...ever.
He has a new update coming soon...which will add even more to it.
No need to go full unroot if you have Triangle away & TWRP

Whatever im on, scrolling is just chunky and switching between apps even with jelly thunder....it is much less on stock but still there

Don't know what to tell ya...mine doesn't. Are you using Nova ? In it..you can change the settings to increase the speed for what your wanting..
Mine even without it isn't chunky or stutter..but is much much faster with the tweaks enabled in Nova.

Im on the same side. Been a flashaholic for years and noticed stock ROM always equal or better. Maybe not about performance But MOST Are Battery Life which I need the most. Enjoying stock 4.12 int S. Africa ROM now and no need to flash anything else.

No issues here with any of 3 different roms. What apps are you running or is it like this immediately after flashing? sounds like something is running in the background causing your problem. Is media scan running constantly? Need more info on what is going on in the background to diagnose.

He is meaning thishttp:// http://www.thefreedictionary.com/_/dict.aspx?word=clunky
The stock rom is chunky. ..it's full of bloat. ..
Most custom roms are de-bloated already.
Sounds like he had a bad install. ..and flashed a stock rooted rom...

Maybe try to reduce the Animated Scale setting under Settings - Developer Options from 1x to 0.5x or below? Toggle GPU rendering setting in there as well.
I also agree that a lot is dependent on your launcher. Nova is good to compare too *only* if you optimize it's settings to set all to "Faster than light"

haha...I am meaning the phone stutters and lags durring scrolling and moving between windows and applications even when using nova and faster than light settings with the transitions to 0.5. It does not seem smooth as it is supposed to be.

I agree. Rooted doesn't scroll as well.

I'm on the newest version of CleanRom. I much prefer it to stock. There are a lot of features I can't live without. Still, the price you pay is with scrolling. It's jerky compared to stock, especially when you are slow scrolling. Fast scrolling is not an issue.

Yeah, I don't know what you talking about. I'm running Jedi X6.1.2 and I don't feel a performance difference, but I do have a lot of nice goodies stock doesn't have.

OP should make a video to show people his problem
I experience none of that with jedi or cleanrom

I know what he means. I also started a thread about jerky scrolling. Some people seem to have decent eyes they just dont realize or never seen a fluid scrolling capable samsung rom. My stock browser is buttery smooth even with heavy picture loaded wep pages. However tapatalk and facebook and some apps are super jerky. Even setting menu of phone is very jerky. Unbelievable. They are jerky when u scroll only with medium speed. If you scroll very slow or very fast its smooth.
This is very annoying for me. So I flashed every available rom and kernel and tried every rom/kernel combo. I think I found the solution.
Seems like The problem is caused by cpu governer + rom type. So I tried some stock roms that are very smooth and that are jerky.
I got the best scrolling with note2core kernel and ONLY IF you select iNTERACTIVE governer. Perseus and other kernels only have pegasusq governer. Once I made it interactive they all became super smooth.
If you are running perseus kernel or such u can also test this by selecting "performance" governer. It basically keeps your cpu in highest level. And your scrolling becomes buttery smooth.
It has something to do with cpu levels I guess. With pegasusq there is not much load to trigger higher cpu levels so it uses low levels.
I suggest you to try note2core with interactive governer.

the lag should be enough, i did it on my galaxy s3 i had one that seemed to have alot of micro lag......if they can see it they should replace it. Most likely they will ask you to show them the problem, tell them you have a friend with the note 2 and you dont see any of this on his phone and think that it must be a bad unit. they should just replace it if its within the alotted time. just keep complaining you didnt pay that much money for a device to be as laggy as a last years gen phone and so on blah blah blah.....they should give you a new one.

Gaming performance - The Amazing Spider-Man 2

Hi all,
Anyone else tried this game? I'm experiencing a fair bit of lag especially on maxed settings.
Running AR HD 7, stock Rom, playing in performance mode with background apps cleared.
Bit disheartening to see lag on a flagship device, but I'm assuming it's most likely **** optimisation with the game.
Running Dalvik, 4x msaa turned off.
I've even got seeder installed.
