[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.

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] Overcome-Hermes, 1.4GHZ OC stable only when in UV -75mv

I was using stock for my gtab and lately installed Overcome-Hermes.
I noticed that the 1.4ghz oc using setcpu is unstable and often hangs in games especially "Dungeon Defenders" using the default assigned voltage of 1500mv
I played with the voltages for a while and found out that the 1.4ghz OC is stable when i set it at -75mv which is about 1425mv.
Is this normal? Aint the higher clock supposed to require more voltage?
Device does not freeze up, not even once so far, when i undervolt 1.4ghz to 1425mv.

i think its normal since it states here: http://overcome.mimzo.com/?page_id=68
"THOUGH FOR HERMES, BEST STABLE SETTINGS SO FAR: -100mV AND BELOW."

My experience with gingerbread UV/OC states that the higher the OC the lower the UV. However, seems that some UV is necessary for OC; especially for 1.4Ghz.
My setting for that frequency is the same; -75Mv and seems stable for a couple of days.
And yes and no, although higher frequencies need more power higher voltage is not a must.
Last note and 2 cents; if it is stable do not bother )

Something is not right here, with Froyo I had -200mV at all speeds - stable withouth problems, but with GB and -100mV the tab already unstable at higher speeds...

[Q] OC/UV settings for battery life

hi guys,
does anyone have a tried and working UV values for best battery life? I don't want any more performance, so I'm not looking for OC, but perhaps any idea what UV stays stable?

Well, it's easy the higher you OC, the more it will drain your battery. As for UV, I can't tell because the voltages are different for every device, Rom and kernel...

Usually undervolting -50mv for each speed will work for most devices, although its not recommended to decrease that much for speeds below 800mhz since it will affect your phone's wake up speed.
And tegra 2 cpu controller only supports minimum of 770mv, going anyway lower than this value will not have any effect.
My advice, try UV -25mv for 500mhz, and the rest above is -50mv. Some o2x can go -100mv, but you need to be lucky to own such device.
Cheers!

Mine is working perfectly on -75.
But when i go to -100, soemtime freezes device, so i use -75 regularly.

trying -50 across the board now, seems to run stable.
brw, how does lower voltage hurt the speed?

I can't really explain clearly since I do not know the technicals, but from what I read in xda, it will affect your speed, meaning 1.2ghz running at undervolted setting will not run the same as at stock voltage. Maybe its an efficiency issue, I do not know.
I thing that i experience, If you undervolt too much the few lowest clock steppings, you sometimes might not able to wake the phone from sleep because there is not enough power to wake it up.
I hope my explanation help you a little, and hopefully someone with more experience can give you a better explanation.

using -25mv ate 1.1ghz and 1ghz, -50mv at 800 Mhz, and -100mhz (750Mhz so its 770mhz because hardware limitations) on all other frequencies!

-50 mv is the limit for the device don't use below -50mv. but it dependes on your device. mine cannot UV it always gives me SOD i think my hardware phone is crap

When did you buy your phone?
I have one of the 10 first phones sold in Sweden and I cannot undervolt mine at all.
Just wondering if there's any correlation between manufacturing time and UVability (yeah I just made that word up).

I run with 1100.. good compromise between speed and battery life i think

[Q] Overclocking the Tab

Hey does someone know the overclock configuration that was posted on the Overcome page once? I'm running on Overcome 4.1 with the belonging Kernel which allows me to get to 1.6ghz (theoretically) and I'd like to overclock to 1.2ghz.
I'd be very grateful if you could help me
Edit: I found this http://forum.xda-developers.com/showthread.php?t=1036020 but does this guide also apply to Overcome 4.1?

Just use Voltage Control or SetCPU. It's really not that hard at all. Just be careful with your voltages-overvolting will eat your battery more but may allow you to reach higher frequencies, and undervolting may get you better battery life but may make your tab unstable.
As a reference, I have my Tab running at 100-1.4 with smartassv2 and stock voltages on the Overcome 4.0 kernel.

thanks ;-) but which sheduler do you use?
for those who also have problems with overclocking and for
the newbies (like me =-D) I found this page which describes the usage of shedulers
and governors http://forum.xda-developers.com/showthread.php?p=19846297

IO Scheduler: CFQ
Governor: Smartassv2
At least that's what I use on my phone. I just left everything alone on my tab.
Sent from my SCH-I510 using xda premium

thanks, you helped me a lot ;-)
I'm using Voltage Control on 1.3ghz with stock voltages on smartassv2 and deadline and it runs pretty stable

Thanks, useful tip for me too.

I use SetCPU
OC max 1.3GHz, min 100MHz
-75mV from 100Mhz --> 1.0GHz and then -50 from 1.0GHz to 1.3GHz
PLUS various profiles to set max to 800MHz whilst screen off etc etc

that's exactly the same that I did =-D=-D=-D

That's pretty much what I have. OP, sorry I couldn't answer your PM, my tab is currently bricked and I haven't had the chance to recover it.

yea I have time =-D that's not so important, just make sure your tab runs again ;-)

This is what worked for me as well, just don't check"set at boot" option till you've tried that speed for a few days and you config proves stable.

Haha, I did check that option when I foolishly set the OC max to 1.6GHz
...I was just able to uninstall between one of the many lopping reboots
Anyway all, sorted now. In fact I have reverted to stock voltage for 1GHz up to 1.3GHz because playing Trial Xtreme2 would cause a reboot when I'd exited the game - seem's all ok now *touches wood*

[Q] Is LiveOC just crap?

Anyone else found this?
I was on CM7.2 with Glitch 13.1 and was able to OC safely to 1.7Ghz STABLE!!! And further more I NEVER had to touch the voltages.
But now I'm on CM9.1 with Devil3 1.4.1 I cannot OC past go 1.2Ghz with LiveOC at 110% giving me a determined CPU clock of 1.3 and a bit Ghz, if you push LiveOC to 111% at 1.2Ghz it reboots and you have to clear NSTool Settings from recovery.
Is it just me or is LiveOC a much poorer idea then the methods for overclocking used by Gingerbread...? Should I try Glitch v14 Beta 6? Even though it looks as though the Glitch kernel project has been abandoned :'(
This is just leaving me with a very s**t taste in my mouth as I was looking forward to Ice Cream Sandwich... anyone else having this issue?

You have to increase the voltages. When you set 120%liveOC, 1000Mhz are now 1200Mhz and you should set the same voltage for it as you get automatically on 1200Mhz normal OC. And you should mind that liveOC doesn't only OC the CPU, so it makes your device faster than normal OC, but it's more unstable. The maximum liveOC you can get are 130%, most users can't put in more than 120%.

Thank you dark_knight35, I will have yet another look at the LiveOC guides kicking about (Glitch's one for example) and see if I can make more sense of it.
But what you say about the voltages on a step after LiveOC is truer than true... can't believe I didn't see it! But I was getting proper annoyed :/
Do you (or anyone) know if there is a kernel out there for ICS that doesn't use LiveOC? And instead just OC's the CPU and or GPU like Glitch 13.1 did for CM7?
Again, thank you
