[POLL] Overclocking, How far does you galaxy Go and S stay stable? without rebooting

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)

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

[Q] Why use UV or OV?

Hello all,
I've a question since some day, I try to find the answer with search but with no success.
Which benefit you can receive with UV or OV?
I think that:
The UV is better for battery life but with less performance.
The OV give a better performance but consume more battery.
If so... why you find many overclock setup with more Mhz but less Volts?
I cannot understand that... it's look like a no sense for me.
I've a Galaxy S with NEO 17 Kernel.
Actually use:
Governor: conservative
Force Minimal freq when screen off: OFF
1200 Mhz -25
1000 Mhz -50
800 Mhz -50
400 Mhz -50
200 Mhz -75
100 Mhz -100
I try this setup coping from other post, because I want the better life battery for "office use" but a good performance when I do gaming... but I cannot understad why of this setting
PS: sorry for my poor english.

How come you think that UV means "less performance"? Core voltage has nothing to do with performance (at least not in the way, you mentioned it)
I think you can found some good tutorials about OC/UV, somewhere in sgs section..so check those out to learn more about this subject.
It isn't always very easy to figure out these things, but it's good that everybody can found lots of information from xda

First of all thanks for your reply.
I "suppose" that under voltage is mean less performance, but I really don't konw.
I want to understand why I have the possibility to under or over voltage and what does mean...
In order to make an example, which different are there if I put 1.200 Mhz with voltage -50 or 1.200 Mhz with +100 voltage?
Sorry I'm newbe in overclocking!

I was using oc for few days and I didnt find a better performance except the quadrant score. Anyway oc is a risk process. If we are not getting that much performance then why should we take risk. Try Darky ROM v10.2RE and flash semaphore kernel you will get a better performance without OC.

oc kernels

can we make a rom for ur mini with a kernel which can make ur mini work on a higher frequency above 800mhz i'm asking this because i saw that galaxy 3 which have almost the same specs can be overclocked to 1ghz?
and somthing else i found there how to make rom for odin from cwm and viceversa here is the link:
http://forum.xda-developers.com/showthread.php?t=1405041

even though it has same specs the kernels are different and currently mini roms are stable with 800 mhz frequency

If you can OC to 900 MHz and keep it running in that freq for daily use, sooner or later your CPU will be toasted since it will be too hot. 800 MHz should be high enough for most games.

i think 800 mhz is good for galaxy mini
don't try to overlock it over 800 mhz or else your sgm will don't work properly
sorry for bad english

i don't wanna overclock it more than 806 ii'm just asking is even possible

My mini doesn't even work properly over the 700 mhz, I think 900 mhz would be the killer of our mini's...
I'm sorry for my bad english...

You reall want to toast your Mini Board do ya?
Its dangerous ... the OC kernels ..

what for oc if you have problem with the battery, you know it that i think make you phone healthy is better

theres a thread that has stock rom with OC kernel..
just view this thread..http://forum.xda-developers.com/showthread.php?t=1464896

????Help me...will ya???

My x8 getting freeze + reboot at 729 MHz ..
I am using gdx + Alfs v08
..
on stock kernel also I use to get this ... changing kernel wont help increase frequency? ??

Try reducing your overclock MHz until it becomes stable.

dude with custom kernel people get 800+ MHz stable and for me its 691... can I do something to Inc MHz frequency ....

In case you missed it... just because "people get 800+ MHz" doesn't mean YOUR chip is able to reach that frequency. It all depends on the quality of the silicone out of which your chip was made and some luck getting a really great one.

Is there any Kernel with CPU OC functionality available?

Hello,
as mentioned in the headline, is there any CPU OC kernel available? I have only found GPU OC kernels but non with CPU OC capability.
Thank you for answer.

Kholks kernel has cpu OC

Whow, what a fast answer
Do you know how high the maximum CPU OC is?

OK, I´ve found it.
Overclocked. GPU @ 584MHz -- CPU @ 1.65GHz(x4)

There is an update coming very soon, possibly today as he's announced everything's working. This new one will be fast as hell and everything will work as it should. The current alpha for stock is OK, just YouTube freezes and reboot just gets stuck so you need to pull battery, other than that its a solid kernel

Realy OC for this Kernel?? I can set to max. 1700 Mhz with different tools, but max. reached Mhz is 1500,same as stock...

1.7 is overkill, no app needs it. What is really needed is a kernel that uses cores better and doesn't cut the frequency when full quad is used. This one for example: http://forum.xda-developers.com/showthread.php?t=2270308

well mine did actually set to 1.7 ghz and the result was very visible in bencmarks

Lol, isn't that a battery drainer? I underclock mine to 1Ghz.

nah, my signature lies as i flashed back to normal stock CM kernel due to the fact that Kholks current release doesnt have wifi, i will wait for his new (or the next werewolf) that has both GPU and CPU overclocked, and then my battery would be F****** XD
and yes, it was a battery drainer
