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.

Enviado desde mi GT-I9000 usando XDA Premium App
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

Hi, I'm tempted to push CPU beyond current 1200MHz, no Undervolting. I want to do a survey on what CPU frequency settings and UV hold you for daily use. :silly:
I'm currently using 1.3GHz/368MHz with smartassV2 governor. Good performance and good battery life on IceColdSandwich 8.2. At 1.4GHz or higher, it's unstable and the phone freezes while the screen is powered off sometimes.
I'm currently running 1420MHz with Ondemand governor, no UV, with no problems.

[GUIDE] *19/8 UPDATE!* 4.3 RESULTS! N7 'Best' Kernel (Performance & Battery Tests)
A lot of people have been posting in these forums, "Which kernel is the best"?
I was intrigued and decided to work this out for myself and share it with the rest of the community.
This is not meant to hurt the makers of these kernels.
But FIRST, it is not a fact that there is a 'best' kernel. 'Best' is an opinion and everyone has a different opinion.
On the Nexus 7, I personally believe there is no 'bad' kernel and none of these kernels I have tested perform badly or lag heaps.
People still like to push their N7's as hard as they can though.
The Main 2 Features people look for in a kernel are:
Performance & Battery Life
Some people prefer performance over Battery, or vice versa, or an all-round kernel.

Nice! This should be a sticky to help reduce unnecessary threads about kernels. My only suggestion would be to run Quadrant 3 times and take the average number. Only because 3 runs will have different results every time

I am testing several kernels here. The fastest for me so far is trinity, but the battery is draining really fast. I then tried the 1400 MHz trinity and things got a little better with a good performance in quadrant.
I am testing motley now and seems good but a little slower than trinity. Home screen doesn't look as buttery as in trinity. I will keep testing a little longer.

Crap...i just had a reboot while using motley and started playing dead trigger. I returned to trinity 111 and it is definitely smoother than the others for me. Maybe it is because it is the first one i flashed and now when i try others, even wiping, something remains and the other kernels don't work right. Who knows....

Can't wait for the battery life results!

I posted about the so called battery life screen shot thread in there thread.
the only way to really test battery life is to start with ful ly charged battery each day. 1 TEST PER DAY or charge cycle.
you will have to get a mathematical equation figured out first .it would have to be something like
cpu cycles x screen brightness x memory usage and s on divided by then another equation to determined battery pull watts im guessing
you would have to keep the first exact on each test device to determine the battery life ..
ok while typing this i have decided its way over my head and quite honestly not sure it can be done ..
HELP My brain now hurts ..
The best way to test CPU performance would be to make sure that all kernels are at the same exact core frequency max, and all cores enabled, on performance governor. Performance governor alone doesn't enable all cores, and benchmarks sometimes don't trigger all 4 cores as on either (it can, but not always, and that can lead to totally different numbers on different kernels).
Some kernels have higher max frequencies then others, some use the new CPU quiet driver and some don't (although this wouldn't really matter if all cores are forced on for testing).
Some kernels have higher GPU clocks then others, some have higher refresh rates then others, some have both higher refresh rates and clocks, etc.
Personally, the best way to judge a kernel is by what features are implemented in it for example, is it linaro compiled? Does it use the old hotplug method for CPU cores, or the new quiet driver? Updated WiFi driver? fsync toggle? Was it built with RNDIS drivers?
Quadrant isn't a stable means of benchmarking (run it 3 times in a row and watch those numbers change), but generally speaking, if the same kernel is compiled with linaro, vs no linaro, the linaro build would be faster (don't quote me on this). Not all those kernels are linaro that I'm aware of.
Also, Jay's buttery smooth tweaks, his fsync doesn't work on franco.Kernel. That kernel specifically uses a different command to toggle fsync, and unless that method was used, any I/O results would be void (basically comparing fsync kernels to non-fsync, where fsync would obviously dominate). And there is even the possibility the ROM you were using may interfere with CPU clocks and voltages unknowingly.
So with all that said, trying to find the "best" kernel, is going to take a bit more effort then just benching with Quadrant
And for my own personal opinion (no hard-testing done) I like franco.Kernel Stock clocks and voltage, fsync toggle, new CPU quiet driver and WiFi driver, works awesomely faux's kernel would be my second preferred kernel, only because lack of fsync control, and getting rid of the CPU quiet driver.

Used Motleys 520 at first, probably still my favorite. Used trinity and both of clemsyns latest. Clemsyns elite 1.8 got too hot for my liking, I'm using the 1.5 UV right now and batteries not too great, but its very smooth. Trinity is smooth as well but Motleys 520 seemed to both perform better and give better battery life at comparable clock speeds to the rest.
So Motleys will be my daily, but I refuse to stop flashing!
this is very helpfully

You can't tell which is best if they are not under the same circumstances. Obviously Franco is top because his only goes to 1.3 which is stock. While others are over clocked... thats unreliable.

I had the most fluid and lagg- free experience with your kernel, only problem is the phone would freeze every now and than.. I tryed the semi extreme version on Anono Rom v19. I couldent say if the battery life is good, because i had to reflash perseus again for stability, but im very pleased with the smoothness and the general absence of lagg. I'll try the medium version now and report back...
Could you post pictures for stwaeks showing how can i put kernel confgratin

Nice try but do you have any plans for an aosp kernel?i like overclock and the extra features but it is too tough to say goodbye to pac rom

Will do but it may be done in the next month, Thanks for your suggestion.
First of all THANK YOU for spending your time on this and sharing your result with us!
Just flashed the kernel! Good news...nothing is bricked
CPU Spy Plus indeed shows 1836 Mhz used! I did´t do anything for that.
You might re-think this. Using 1512Mhz instead by default and let the users choose that high speed CPU mode themselves as it may not be stable on all devices.
That 324Mhz added is a huge step...there is no step in between possible?
What about voltages. Did you modify anything? Is the voltage raised to achieve the high cpu frequency? Please post some more information about what happens here...
In fact I´m just running Antutu to see general stability on my device.
VERY BAD score. Before your kenel there were 20300 points. Now with OC only 19746.
=====================================================================
EDIT: Just recognized.... several questions are being answered by Antutu CPU Master.
1512 IS USED by default!
1620Mhz and 1728 Mhz are there to choose and of course finally the 1836Mhz.
Scaling is interactive by default (changed to my fav ondemand)
I/O Scheduler is cfq by default (changed to my fav noop)
Antutu Score @ 1836Mhz: 16077Mhz ???
Lower than without OC? Needs retesting (14230 point when setting max to 1836Mhz and Min to 1512Mhz(!!!???)...maybe the benchmark is wrong...Will give it some time to see if I myself feel a speedup.
After Restart Antutu Score ends up @ 19761 points...not bad. but clearyl not enough looking at the massice OC done. REBOOT! Tab just rebooted! So 1836Mhz is not stable at mine! Trying 1728Mhz now instead.
18139 points....this kernel lacks some serious power if we can believe the scores of antutu. This is a V0.1 so nothing to worry too soon. You´ll make it find it´s power
Switched back to kernel from pulser_g2 (http://forum.xda-developers.com/showthread.php?t=2444452) and 19908 points without any OC! You may look into it.
But please answer the other questiones I wasn´t able to clear myself.
Greetings

Sorry for my late,
I've tested Antutu with 1512MHz and 1836MHz. For my Tablet Z, I got ~20000 (1512MHz) and ~23000 (1836MHz).
My Tablet Z has fast binning CPU. Can you please tell me which binning your CPU is? Thank you!
hard to tell...did taht thing in Terminal emulator....it tells me "1".
Not fast or slow or anything...

Don´t know....after the disastrous performance of the first release I of course switched back to stock.
Now there is the new version which does not cut performance in stock mode.
I´ll OC now to 1728 Mhz and see how it performs with that....battery life is not really good with stock so if you are already asking...FORGET ABOUT alternative kernels not optimized for battery.
That is why I don´t use CM oder AOKP on my Note1. I just eats the battery for breakfast....
OK OC just seemed to scale...20300 points (ca. 19300 at stock speed)...trying 1836 Mhz now.
17389 points....clear drawback....possibly because my device seems to have a bad CPU from what I´ve learned....wanted to use the 17xx Mhz anyway....oops....device just rebooted....my device just isn´t capable of the max cpu setting. :crying:
Anyway the working 1728 Mhz working is great news!
Will give it further testing...
I have two APQ8064 devices, Nexus 4 and Tablet Z. Nexus 4 is 0 (slow), it will reboot sometimes even on [email protected], the Antutu would force close and red light of death would happen if you ignore it and attempt to run again. While my Tablet Z is 2 (fast), this can run at [email protected] and got 23XXX in Antutu.
I don't have an idea which frequency can the 1 (nominal) APQ8064 clock at, but I think [email protected] will be OK. Also, keep eyes on the CPU float-point section in Antutu. At 1512Mhz, it is around 2000. At 1836MHz, it is around 2200. If this drop lower, just pull up the voltage BUT NOT TOO MUCH!!!

Raising voltage is not an option to me. But anyway...which app do you use for that on tablet Z?
What App do you use for cou control?
I use No-frills. Do you change "interactive" and or "cfq"?
Numbers right after reboot and stopping some unused apps...just stock apps running...
2729 / 930 / 1112 / 1050 / 511 / 927 / 1436 / 5278 / 696 / 600
>>> 15269 points @ stock !!!
switching back to stock....

I would like to know this as well. Also, how do you check to see which processor you have? (0,1,2; slow, nominal, fast)

What is the terminal command to find out? I also considered custom retelling to add some processing oomph. On a per app basis, but reading this... Stock SGP311 on 4.2.2 is chugging fine just north of 20000 points on Antutu. Can we compare Versions? Mine is 3.3.1. I faintly recall reading they mixed up some benchmarking internals because some corporations found loopholes to cheat / inflate scores on new to market devices, maybe that's the discrepancy there?
Another wild thought, could there maybe be, aside from different CPU Models, different kinds of cache / memory scattered through the devices? Would not be the first time a sub par. Cache/Memory bottleneck severely strangled a nominally and factually quicker CPU into much lower overall results. Much depends on weighting within Antutu
Man, what happened with your kernel? We need some stock kernels for 4.3
