How far is your Galaxy s stable?
mine just hits the 1.1GHZ, beyond that only crashes no matter which voltage i Use. please Use the poll so we have a good picture of what the average galaxy s is capable of..
also comment which version of SGS you are using and 8gb/ 16 Gb etc..
i9000m
PS this thread should be moved to General
had mine at 1.54ghz running MIUI with tk glitch kernel.
was amazingly fast, but my phone got hot quick, i dont like OC'ing i feel it may do more harm than good in the long run.
others may and will disagree but thats my opinion on it
Mine with 1.3GHz OC and some Undervolt is perfectly stable.....

Agree with the chef ...
Although I can overclock to 1540MHz it does get hot and Im sure it will do damage in time ..
1300MHz is a great overclock ...
It will be interesting to see what my SGS 2 can be safely overclocked to
1.2 GHz seems ok for me - with UV
Doesn't really get hot.
Running mine @ 1440 MHz with MIUI but i think I can go higher if I want . I have the 8 GB version
1.3 and very stable and with great performance both q score caffiene mark and in daily use
Which voltage are you using?
Mine seems to freeze on voltages above the 1.3V,
above the 1.2 GHZ always freezes. I,m using darkeys 9.5 Rom.
someone some advice which rom is the best for OC, (just for benchmarking) for once.

Mine can handle up to 1.3-1.4ghz
Im getting stable speeds of 1.7ghz. Im on watercooling though..

1.4ghz is my max for full stability. 1.5ghz works fine (no reboots), but the CPU occasionally gives an invalid result during calculations, e.g. during benchmarks like linpack, results can sometimes be inaccurate; 1.44ghz also seemed to work, but I picked 1.4ghz max for longevity/reliability.
UV Values are:
100mhz - 200mV UV (750mV)
200mhz - 150mV UV (800mV)
400mhz - 100mV UV (950mV)
800mhz - 75mV UV (1125mV)
1ghz - 50mV UV (1200mV)
1.2ghz - 50mV UV (1300mV)
1.3ghz - 0mv UV (1400mV)
1.4ghz - 50mV UV (1400mV)
Max UV were found by starting from 100mhz Max frequency, decreasing UV until stable for 5 minutes of software decoding of 720p MKV, and then increasing Max frequency one step. Occasionally the previous step UV needed to be decreased by 25mV to obtain a stability at the next frequency step.

Guys, if you wanna push your phones to their full stability limits- play on Shadow Guardian game...)

I can run my SGS stable at 1540 MHz with glitch kernel in MIUI 1.5.20 ROM.
Total stability in a 48 hours stress test.

Mine is stable at 1.5 Ghz with a 200mv undervolt, but only if I select it as a single frequency.
For multiple frequencies, I was stable at 1.4Ghz on an earlier kernel, but it's slightly unstable now... I'll probably try tweaking the governor.
I'm on a i9000m using tk-glitch's V9D-VC and CM7 #11 build.
By the way, shouldn't this thread be in general?
I am on MIUI v3 and CM7_SGSMTD_platypus-kernel_20110522_r0_quorra-prer11_test4-r2 kernel.
I don't use undervolt settings and 1.2 Ghz is fine for me; above values generally don't work stable.
By the way, 1.2 ghz is almost enough for all games and operations, I did not run into that pushing apps for high oc's.
Regards.
1.44GHz, extremely smooth and stable!
Never seen an option to go above 1.54, but 1.54 works flawlessly so I've chosen 1.5 in the poll. (16gb i9000)
1.3-1.4 GHz tkglitch kernel Miui v3

It's not the ROm it's the KERNEL who can oc, i adviise using XAN, hardcore kernels in 2.2. or gto's ginger kernel at 2.3 they are stable and 1280 i guess it's the limit not to warm up
But a questin what send me an undervoltage config, to 1300 if the gpu games work for someone at 1300mhz

I'm running Overcome Hermes 2.0.1 on an AT&T GSM Galaxy Tab, and I'm using SetCPU for both overclocking and voltage control. Seems like everyone has a Galaxy Tab that can be overclocked to 1.4Ghz except me. I want to join the party.
When I overclock to 1.4Ghz, for the most part everything runs fine, but when the CPU really gets stressed I get crashes. This has forced me to disable the 1.4Ghz step. This is despite the fact that my CPU performs like a champ otherwise, and I've managed to undervolt all the steps except for 1.2Ghz by quite a bit.
Is there a way for me to give the 1.4Ghz step a slight voltage bump to improve stability? SetCPU doesn't seem to offer an overvolt option, is there a way to edit a file and manually change the voltage? Where are these voltages for the overclock steps being read from in the first place?

If you do a quick search, there's a voltage control app floating around these forums.. voltage_control_gt.apk i think..
Donate version of voltage control supports over volting. Bear in mind increasing boltage doesnt necessarily mean more stabilty at certain clock speed.
But it does mean a higher chance of ruining your motherboard.
while i was searching the internet i came across to that...

these phones uses the same processor but on different frequencies.
so my question is: is it safe to use daily the cpu at 1.5ghz of DHD ?
Some phones can handle a higher o/c than others. I've been running mine at 1.2ghz for months now with no issues. I can increase that but I've never felt the need, although many others do ;-)
Yeah, i think 1.5ghz wouldnt be any problem for most/all devices.
With my Milestone back then, which had 550 mhz, i personally was running between 800-1000 mhz, alot others were running even 1200 mhz there.
But on DHD; i personally would do (max!) 1.2 or 1.3 ghz, because this is absolutely enough for most Roms to be smooth.

the max i overclock for daily basis is 1.2Ghz but when i tried 1.8Ghz back when lee released his nutter kernel my phone froze.
But i did read somewhere the cpu can be overclocked to 1.5Ghz without any issues but over that people do get some problems.
No!
Using any CPU frequency that is not default ( underclocked or overclocked ) requires testing and manipulating the various variables. The CPU needs to be in sync with the GPU and the other parameters. Needs modifications in the kernel itself. The device is not made to run at those frequencies. You will burn your device, sooner or later.
Hi, Now I want to get performance and smooth running games. Right now I get 20-30FPS on GTA VC on JellyBAM rom. I want to undervolt GPU. Now is 400mhz at 1100mV it is safe to add more mV? Like +50 or +100? and do I feel any difference?
Its rooted, of course. And when I load it it says its working, checks stability, etc. but the phone doesn't get any hotter. I can raise the GPu speed to 400 MHz and it doesn't get hot. Benchmarks stay the same. The phone feels the same.
Does Tegrak work with jb?
usually OC doesnot show a lot of differences. Bechmarks stay almost same
It works perfectly on cm10.1 for me

It will works only if the kernel suppport overclock function.
Actualy there is no overclockable kernel for any TW based rom.
you can overclock on Stock JB kernel using this app.. CPU can run at higher frequencies
