I have miui le 5.1 with glitch v12 and i tried all 3 versions of it but cant oc past 1500 everytime i goto 1600-1700 it freezes or i get a black screen
any help?
That's not unusual at all. Most Galaxy S phones are unstable past 1440, much less 1600 and above. I can't get past 1300mhz unless I'm using Glitch ML.
If you followed the instructions in the Glitch Kernel developer thread, specifically with attempting to undervolt for stability, and you still can't get anything over 1500mhz stable, then it's likely your CPU isn't capable of being stable above 1500mhz. Heck, I can't get 1500mhz stable myself, but I can get 1400mhz stable with 75uv to boot.
Just out of curiosity, but why do you want to Overclock that far? Can't imagine any games built for the Galaxy S would lag above 1ghz. Just want to see if you can, perhaps?
Consider yourself lucky. Oh, and drinks are on the house!
thanks! i got 1600 stable its just i want to play ff8 on psx4droid and everything is perfect but it lags at certain spots but thanks soo much for your reply! its truly appreciated
Bah! Forget using a PSX Emulator on your phone. Do what I did when I played FF8 for the first time. Plug your computer into your TV, plug a Logitech Rumblepad 2 into your computer, load up the emulator with all the enhancing effects like Shaders and HQ4, set up a quicksave and quickload button, and go to town

hi there
i am a noob i just brought vibrant previously using htc hero...
i tried to flash bionix and bionix fusion with the new 1.2 ghz oc...
phone works well except when i play games like asphalt, neocore my phone freezes then i have to remove the battery and insert again...
what could be the problem
i am using J12 RADIO....
PLEASE HELP ....
VIBRANT IS 100% AN IPHONE KILLER ... LOVE IT....
mine does the same thing not really sure why yet but if your using setcpu just put the speed at 1000 on both the proformance is unnoticable

i had kept setcpu max 1000 and min 200 still it freezes when running heavy graphics games
Your phone might not play nice with that kernel. Try flashing core 1.0 instead and see if that helps.
Yes, not all phones are stable when overclocked. Use the stock kernel and you should be fine.

^^^ this, but I'm sure you knew that since it says so every where.
My phone runs great at 1.2Ghz with JAC's XMOD Voodoo kernel, but locks up constantly with Core, OCed or not. Try swapping kernels, but don't give up on the OC yet.
I'm having the same exact issue, mine will just lock up for no reason sometimes as well. I'm not sure what it is, I kind of feel like it's the rom. I had problems originally with fusion to begin with. Maybe I'm not doing a proper procedure to install it?
Is it because I'm wiping and going straight to fusion? Please anyone else are you having this issue, I'm getting frustrated and feel my phone is slightly useless like this. I HATE stock.
Edit: Setcpu doesn't let me set to 1000 with Core 1.2Ghz, I can only get 1000 if I use Core 1.0Ghz (obviously). Again though, same issue regardless.
Core is still in beta status and not all the bugs have been worked out yet. The issue the OP is having has been mentioned before in the Core thread in the Dev section and on the TeamWhiskey.com forums as well.
OP: To alleviate the freezing issue you're having, flash the 1.0GHz CoreV1 instead of the 1.2GHz CoreV1

I have been using the franco.Kernel from the first release..... And lately I've been having a couple of problems.
The first problem is with random crashes. This occur when I'm playing a game or browsing. I didn't experience this problem before and I have the phone for 6 months now.
I've OC'd the CPU to 787/245 MHz with Smartass governor. The problem is recent (since v11 onwards). Although v13h was stable under heavy usage. I've tried other kernels, re-flashed the ROM (void.ECHO) and the problems never occurred. It seems that it has something to do with Franco's Kernel. On DookMatt's kernel I was even able to keep the phone stable on 806 Mhz using performance governor; tried just to make sure it wasn't a hardware problem.
The other problem with the kernel since v12 is during file transfer on USB storage mode. The files take a long time to copy on to the SDcard and the Writing/Pasting speed drops to 0 kB/s and again speeds up. Then slows down again, speeds up again and so on.
I've tried transferring files using a standalone USB card reader. On another phone, different ROMs and kernels and it seems that the problem is with the kernel.
I could've posted this on the Franco.Kernel thread but it seems that I can't cause I don't have 10 posts yet.
I'm not a n00b and neither am I a genius. So before anyone points out that it's this or it's that, I've told you about what I've tried and what I've found.
Don't get me wrong, I love the work that Francisco has put into making the Kernel and I really appreciate the time and effort he's put into it. Also I love the constant updates he releases to make our phones ever more faster and responsive. This is just a little problem/bug I found and would really love if Francisco would solve it on the next release.
If anyone have this problem or could help me with this, then I'll be very grateful. And if anyone could post this on Franco's thread then may be he'd help us out.
I would say the problem might be 787 oc. When you say the phone was stable at 806 MHz in other roms does it mean that it was stable at standby? Or were you able to play heavy games at 806 MHz? Try reducing the OC.
As for the fluctuating sd card speeds, I have noticed this happening with all the roms I've used, don't know why you are facing this in franco kernel only.
748 MHz is ur answer
Yup... I've played NOVA and Assassin's Creed on 806 MHz on DookMatt kernel....
And also the stuttering while writing onto the SD card has only been experienced since v12 of Franco's kernel.
I hope he fixes it..... because it takes ages to copy stuff onto it.
The random crashes during gaming have disappeared since installing ChainFire 3D drivers.... It's also increased the performance quite a bit!!!

As for the original thread from Chainfire himself....... http://forum.xda-developers.com/showthread.php?t=1087427
He does say that it requires Open GL ES2.0 and in my testing the Electopia Benchmark which makes use of Open GL "PROPERLY" does work on P500.
My benchmark scores on 729/245 MHz is 17 FPS on 320*480. Chainfire doesn't increase this score, but the use of QUALCOMM (ATI) plug-in does increase real world performance in games such as NOVA and Assassin's creed. By this I mean that they render more smoothly, which otherwise would be stuttering.
The Link to the API for the plug-ins is........... http://www.mediafire.com/?bit1zhjplxygh4g I've attached it on my post as well!!
BTW.... Thanks for all the effort Francisco. Appreciate all the work.
You should share what speed and voltages you are running at, I figured it would be helpful to give other people ideas of where to begin trying their voltages at for undervolting purposes. So, what's your lowest voltages at the highest clock speeds?
I'm using SetCPU's standard voltages. 1.8/.38 normal, .87/.38 screen off and over 130F, 1.2/.38 battery less than 50%, 1.8/1.2 plugged in. Getting 4-5 more hours per charge!

Here's the values I've currently got in my Permatemp Root .bat file (thanks Eugene!): scpll_l_val=24 vdd_uv=1060000
That gives me 1.296 ghz at 1.06 volts. I know 1.3 ghz isn't much of an overclock, but this phone is already so fast (especially compared to my old Hero, lol) that I'm not really craving any more speed ... what I'm most interested in is undervolting for max battery life. From what I've read the stock voltage at 1.2 ghz is 1.18 volts, so I'm a little under that right now. I tried 1.00 and 1.03 volts and got reboots every time, but 1.06 volts runs rock-solid reliable for me at 1.3 ghz.
is that really even noticable? the LCD draw most of the power typically

Someone in the OC topic was asking about UV at stock speeds. You're close enough to stock that you should qualify. You should go post your results in that thread too. They'd be happy to see them.
I'm running @ 1.78GHz with a vdd of 1300000. I'm going to try and go lower... maybe 12800000.
I have it overclock to 1728mhz but dint know where to adjust the voltage. Does setcpu does this or i need a different program to read voltage/change voltage?

You adjust the voltage when you type the ADB command to OC. If you're using a script that does it for you, you will need to edit that script and look for the vdd_uv= line.

What do you mean by "is that really even noticable"? It's certainly calculatable ... it's an 11.3 percent improvement in battery usage by the CPU. If you're saying that's not very much, well, it's all relative. If you're saying you're not interested in saving a little battery when it won't cost you anything to do so, that's fine with me. If you're saying that no power-saving effort is worth any consideration because the LCD is the biggest power draw of all and that's the only one that matters, then why did Qualcomm bother to develop asynchronous cores and low-power audio modules and low-power GPS modules? I mean, hey, the screen is all that matters, right?
Or did I misread your statement?
Edit: Sorry for coming across as so argumentative, I just don't understand why you're taking the position you are.

+1! Would have thanked you, except I'm at my limit.
I'm at 35 @1450000. I know I can go lower, but if I overclock, I want stability not battery life
On another note: I can't wait until we have source, custom kernels, and I finish up the viperMOD app to get support for the E3D. Will be one awesome beast undervolted!
I'm at 1.56ghz and 120000 voltage.
Runs stable, get a nice speed boost without killing my battery. Am going to try a lower voltage. I've read the could will default to stock speed if you go too low though. Guess I'll find out.

No, if your voltage is too low, your phone will freeze or instanly reboot on you.

I am currently testing scpll_l_val=22 vdd_uv=1010000 for undervolting purposes, 1000000 caused a reboot, 1010000 has been holding up well under stress tests..
If one of you guys who are overclocking could test this video clip and either diceplayer or the diceplayer free trial in the market - I would appreciate it:
http://www.movie-list.com/forum/showthread.php?t=27232
Supposedly - the Samsung Galaxy S2 can play 1080P + AC3 MKV's smoothly. But the Evo3D and Sensation lag a bit according to the developer. I tested this file with my evo3D and it looked like my Evo3D stuttered every 3 seconds or so. I'm just wondering if an overclock would smooth out playback - but I haven't installed temproot.
For those of you overclocking just for battery savings, I am currently testing
adb shell insmod /data/local/tmp/8x60_oc.ko scpll_l_val=22 vdd_uv=1003100 and have been stable so far, this is the absolute lowest I can push it at 1.2Ghz on my phone, can anyone else match this or go lower? I think it will be helpful to start establishing these values now so kernel makers will have some ideas of how far they can push our phones.

Speed = 1.5GHz.
The default gallery player plays it perfectly, but there's no sound.
RockPlayer plays it very choppily, but has sound.
Dice player plays somewhat smoothly and has sound, but there are lag moments every 3-6 seconds as you said.
It's a software issue.

Right noe I'm sitting at 29 (1.56ghz) with a UV of 1170000. Tried 1150000 but phone immediately restarted. And 1160000 restarted after a while. This seems stable so far. Haven't totally stressed it yet though.

Thanks for the check! I was wondering if there would still be lag with an overclock - that's disappointing. Supposedly the SGS2 handles files like it with no problem.
OC Script
Here is a batch file I created to make it easier to OC. Basically just the Rooting script with a menu to select the speed with delays built in.
Rename from oc.txt to oc.bat if you wish to run the file.
You will most likely need to change the voltages to match your phone. My phone has been very OC friendly.
Currently running 1188mhz @ .97 Volts with no issues. I have been able to OC up to 1890mhz @ 1.32 volts.
Have not tried to go lower on the voltage at 1188mhz yet...

Yep, slow the overclock to 1.5 your phone can't handle it, neither can mine. Some can and some can't but other than running a nice CPU test to show off to your buddies you don't want to push your TB like that on a daily basis. I have mine set to 368/1.02 and happy as can be with the extra battery life I get from my phone.
If I helped you in any way please use the thank you button
Alrighty i have mine set to 1.4 extremely undervolted and i get 9-10 hours battery life with heavy use thank you

Hello,
I have a few issues with IMO's lean kernel that someone might can help with. 1) Extreme settings 2 and 4 cause instant phone freeze and reboot. 2) Option 3 works for the first minute or two after boot but then freezes (CPU spy shows 1.92 GHz runs smooth through boot). I believe it to be caused by the ramp up/down of the governor or possibly a script/setting messing with my system.
I am able to run very stably and smooth with a top CPU speed of 1.6 GHZ( 1.593 GHz on A05P). Any ideas on what I can do to increase the CPU speed so that the system stays stable? Your input is much appreciated. Thank you again for helping this poor noob.

Don't OC that high, simple as that. There is no need to run the phone constantly at 1.9ghz.
Just curious is most people who root/use custom ROMs overclock, and if so, what settings do you typically use in SetCPU?
I'm using a S2, rooted with latest Unnamed ROM and find myself contemplating if I should make any changes with SetCPU. Lots of options, and Unnamed has all the different governor options, etc. just really looking for some best practices that people who overclock often.
Would appreciate seeing what you consider to be stable overclock options that give a good boost without causing excessive heat/stability issues.
I'm coming at SetCPU with limited experience so I do appreciate any tips that might see rudimentary, or if there are better resources that teach about this I'd appreciate any links as would like to get a better technical understanding of all this. Thanks in advance.
I use No Frills CPU, and I just set it to 1.6 max/ondemand. Absolutely no heat issues or stability issues, so I just stuck with it. Battery life is good.
most maybe but only by a little bit. a good number of people underclock and undervolt their devices to try and get better battery life. to be honest, the newer phones dont need overclocking to handle the current apps and stuff. the older phones like the nexus one and older need overclocking tho. i leave my gs2 stock. what we really need is dual core support before OC becomes worth it on my phone. ymmv
I have never overclocked mine, phone runs smooth as butter at 1.2 so I don't see the need to go farther. Plus I like my battery lasting more than 24 hours...
I overclock my s2. im running unamed 1.3.0. I like run different speeds at different at different battery percents. 1.6 till 75% 1.4 till 50% 1.2 till 25% 1000 till 15% 800mhz till dead. i had some problems with 1.4 ghz but i tweeked the voltage and that did solved my problem. I'm at 50% battery with normal usage. display 1hr 25mn phone calls for 47min and android os for 56min. my phone doesn't get any hotter then it did before i overclocked. I just did it to say i did. It will prolly help a little unless you like emulators then it will help alot. i have to overclock my iconia a500 to 1.6 if i want to play n64 games.
I'm on UnNamed 1.3.1 with the latest entropy dd kernel and am very happy with the stock CPU speed
